SPECIALLY DESIGNED
SPEED BOATS
Chasers "To Fight Pirates
And Smugglers
The smuggling and piracy evu round the coast of China is to have a severe check in the form type very fast revolutionary armoured "Chasers," Idily armed and carrying a considerable crew. .The first of these boats, which were thought of and have been Scott- designed by Mr. Hubert Paine, was supplied to the Chinese Maritime Customs by the British Power Boat Company, of Hythe, Southampton.
They are unsinkable because, not only are they armoured, but they are divided into a number of water-tight compartmenta and can be haled in, a number of different places and still proceed at speed.
Tag officers, who, together with the crew, will sometimes be com- pelled to live aboard for several days at a time, are provided with Quarters extremely comfortable
in the armoured section of the vessel.
WELL PROTECTED.. Large opening windows are pro- vided-but these can be complete- ly covered by sliding panels of armour plate thus making the compartment absolutely safe dur- ing a raid. 'The engines are also protected by armour whilsta number of fuel tanks in different parts of the boat are also armour- ed, and remove the possibility of failure from lack of fuel.
The element of surprise will be completely in the hands of these boats, because they can lie in very shallow water, well out of sight, and" when suspicious-looking craft come into view they Can puunce upon them at a speed of half a mile a minute (the actual speed cannot be disclosed for ob-.. vious reasons),
Powerful searchlights will help the craft at night, and the arm- Ing. which has been given the most careful thought by Mr. Scott-Paine, is such as to place ven very large smuggling and pirate craft at their mercy. The most modern wireless transmit- ting and receiving equipment is fitted, enabling the boats to maintain contact with headquar- ters and all other Customs ves- sels in the vicinity.
Laken Precautions have been Rgainst the possibility of the enemy faction mingling with the crew and taking charge of the boat during a rald. Armoured steel doors are fitted each end of the control and citadel compare- ments, also the engine-room. These doors are only openable from inside, and whilst the of- Acers can go forward into the crew's quarters, the crew cannot get into the control compartment. The boats can stay at sea in the very roughest conditions. Recently a trial sea passage was made during terrible conditions. with a 60-70 mile an hour gale blowing and huge seas running. High speed were maintained and the boat's company experienced little or no discomfort.

ELEGANT APPEARANCE
Unlike so many patrol traft, the new "Customs Chaser is of elegant appearance, with
atrik-
difficult targets for aircraft at- tack, that a batch of them will be infinitely more dangerous than large; expensive single ships with very heavy armament and crew, These craft
therefore be considered as a precursor to fu- ture flotillas of "mosquito" fght- ing, craft, and may prove of in- tense interest with regard to ship design in the future.

DAZZLING WHITE LIGHT IN NEW ELECTRIC LAMP
Spectrum With Mercury
Lines
The attempts to increase the light output of the hotcathode mercury-vapour lamps which are now being increasingly used for street lighting, have led to an in- teresting result. For, as an outcome of experiments made in the Re- search Laboratories of Messrs. Philips Lamps Limited, 145, Charing Cross-road, Londen, W.C. 2, it has been possible to obtain a lamp, which not only gives a considerably greater brightness.. but is much smaller in size than those that have been employed - up till the present time. As was quite logical, the investigator first sought to achieve his object by increasing the dimensions of the lamp, but as there were obvious limits to progress in this direc- tion, the alternative of using air. and, subsequently water or oil, cooling was tried. The resulta were highly encouraging, though quartz had to be substituted for glass as the tube material, this being the only substance which is both transparent and capable af with standing the tempera- tures generated.
A lamp embodying these prin- c.ples has now been placed on the market under the
name of Philora. It consists essentially of a quartz tube 10 mm. long with an outside diameter of either 6
or 3 mm.. depending on whether the electrical loading is 600 watts or 1.000 watts. The wu'ls of the tube are compara- tively thick giving an internal gas space with a diameter of Z mm. -or-- 1 --- mm -- respectively Theoretically, the lamp may be of any length, depending on the output required. This little tune is provided at each end with a tungsten wire electrode, which is sealed into the quartz, a ring of special glass. being interposed to allow for the difference between the coeficients of expanion of the two, main materials.
The consumption is about 60 watts per millimetre length of discharge. the current
being and about 1,35 amperes.
the brightness attained is said to be. as high as 450, candle power per square mm. (260,000 candle-power per square inch, the tuminous. efficiency being from 50 lumens to 60 lumens per watt.
Perhaps the most interesting feature of the lamp is the white- mess of the Light emitted. Spect roscopic examination, in fact, reveals à continusus. spectrum with very much broadened mer- cury lines. This continuous back- ground extends throughout the visible spectrum including the réd. The result is that there is relatively Little colour distortion.
LUMINOUS EFFICIENCY A lamp of this pattern but without cooling has also been de- signed. This, of course, has a lower rating and the light emitted - is slightly less white owing to the smaller proportion of red rays.

ENGINEERING FIRM JUBILEE The year 1935 marks the Golden Jubilee as a company of Massrs. Ashmore, Benson, Pease and Com-- pany Limited, Parkfield Works, Stockton-on-Tees, the arm having been incorporated in 1885 as a Imited company. As a' souvenir· of the occasion, a handsome - Justrated brochure, edited by Mr. Benjamin Peat, the secretary of the Company, and containing a briet history of the firm, has been. produced." The activities and achievements of the Arm from "small beginnings in 1876, and, its subsequent substantial growth are briefly recapitulated. A happy feature" of the firm is the long Bervice of many members of the personnel, and it is gratifying to note that some 30 per cent, of the employees Have spent upwards of 25 years with the Company,
Its laminous efficiency is about 40 lumens per watt, the consump- tion being 70 watts, while, the length of the discharge is 20 mm.”

New Speed Records
The first records since the Asso- ciation of International "Recognis- ed Automobile Clubs passed its resolution in Paris to recognize speed records made by compres→ sion ignition engined cars were recently obtained on the Brook- larida truck at Weybridge, Surrey, by, Reg. Munday, driving his Per- kins Diesel-engined Thomas Spe- cial racing car. After covering the flying kilometre at a speed of 94.70 mph. Munday went out to make a series of re- cords from 50 kilometres to 100 miles and for one hour. The car ran most consistently, keeping a steady pace between-88 And 89 mph, for the hour's run.

The 18 h.p. engine ätted to the car is known as the "Wolf", manu- facture i by F. Perkins Ltd., of Peterborough; it is of a type used extensively for commercial vehi- cles, but in this case was specially tuned and its reciprocating parts lightened appreciably from the standard. A noteworthy feature of this engine is its wide speed range -from 300 to 4,000 R.PH
Owing to its high brightness and luminous efficiency." Its small size, and the spectral composition of its light, combined with the absence of thermal inertia, it is claimed that the new lamp is specially suitable for use in cases where it is necessary for a con- centrated beam to be emitted, as in cinema projectors and light houses. This claim is justified by "the fact that the brightness or the carbon-are lamps usually employed for such purposes is not more than 176 candle power per square milimetre. while, as we have said, the brightness of the philera lamp is some two and a half times as great. Moreover, the maintenance will be lesa. The very small dimensions of the new lamp should also enable a considerable reduction in the size The Diesel engine has made of the optical apparatus used for very rapid strides during the last projection to be effected.

The The result is an increase of 100 per cent. in screen illumination. To allow of this being done, the movement of the film and the extinctions of the lamp have to te synchronised, so that the change of pleture occurs when the lamp is out. To do this, however, presents no difficulties. For this application, the presence of cool- ing water s an additional ad- vantage, as the absorption of heat in increased and the re- duction in the size of the lamp housing is facilitated. The. lamp should also be suitable for use in film studios, owing to the highly artistic properties of the light and the absence of heat radis- tion. Finály, it is hoped it will and an
