DOOR FURNITURE

Three door handles have been add. ed to the Stirling Suite of matching door and window furniture. Like other items in the suite, they are designed in satin-anodised aluminium.

The handles are of an identical shape, in three sizes, the two larger sizes incorporating an unusual fixing device. Two special screws are first screwed into the door, the handle is fitted on top of these, and two small grub screws, operated by an Alan key provided with the handle, tighten against these door screws to hold the

handle firm. This allows the handles to be fixed in different positions on op. posite sides of the door. The smallest of the three handles is 41⁄2 in. (114 mm.) long and projects 1-9/16 in. (37 mm.) from the door. Sizes of the other two are: 7 in. (178 mm.) long with a projection of 2 in. (51 mm.); and 10 in. (234 mm.) protecting 2-11/16 in. (68 mm.).

LIGHTING FITTING

A suspended light fitting, known as the Wide-Lite Industrial Downliter (HID), has been introduced to provide a sealed, dustproof housing for a mer- cury-vapour lamp. By keeping the lamp and inside reflector free from dirt, and insects, this type of fitting ensures a high level of illumination over a long period of time in locations such as engineering works, garages, and swimming baths, where fittings cannot be reached easily for regular cleaning.

Manufactured in two standard sizes to house 400- and 1000-w. lamps, the HID fitting resembles a truncated

pyramid in shape, its four sides sloping upwards to a sheared-off top. It is made of aluminium and aluminium alloy and comprises an inner reflector,

Wide-Life Downliter

an outer protective housing and a bot- tom panel of shock- and heat-resisting glass set into an aluminium frame which is hinged along one edge of the outer housing.

The specular aluminium reflector inside the fitting directs a high per- centage of light downwards and is claimed to provide a useful light dis- tribution when the fitting is installed with a spacing/height ratio of 1:1. The outer housing, made of heavy-em- bossed aluminium, incorporates ven- tilation slots around its base and at the top so that cooling air enters through the lower slots, passes upwards be- tween it and the reflector and emerges from the top vents. This flow of air, in addition to lowering the temperature inside the fitting, also serves to divert any rising dust or dirt from the front glass which, in turn, is kept firmly pressed against a silicone-gasket seal to maintain the general dust-proof con- struction.

Weighing 15 and 21 lb., the 400- and 1000-w. versions of the HID fit ting have overall dimensions of 1 ft. 3-3/8 in. square by 1 ft. 34 in. high and 1 ft. 7-1/8 in. square by 1 ft. 7 in. high.

GAS DETECTOR

A remote-monitoring gas and va- pour detection system, known as the Becorit RMS4, will give early warning of the

presence of gases and vapours in multi-storey buildings and flats.

The RMS4 is a fully-automatic con- tinuous monitoring-and-action system with visual and audible alarms to suit most applications. It can vary from the simplest single-channel control unit comprising detector head, switching

unit and alarms, to complex multi- channel systems with automatic power-cut-off facilities and standby battery supplies. The illustration shows the control panel of a seven- channel system.

Detectors are located at strategic parts of a building or installation; and if a gas or vapour leak occurs, this in- formation is relayed to the control panel, where visual and audible alarms are fitted. Fans can be provided to clear potentially-dangerous gases; and in certain applications, such as com- mercial or domestic multi-storey build- ings, the RMS4 can cut off the supply of gas or isolate electric power until the gas leak is repaired.

The minute detectors comprise heavy-duty pellistor filaments for con- tinuous operation. Diffusion takes place through a sintered-bronze disc which acts as a flame arrester, and an

·

Becorit gas detector active-carbon filter is incorporated to filter filament poisons. The signal in- put from the detector is fed into a d.c. linear amplifier in a special module which contains amplification, switch- ing circuitry and alarm-level settings.

A meter on the control panel gives direct readings of a percentage of the lower explosive limit, and a test switch gives alarm conditions when pressed. The control panel has a red alarm light which is illuminated if the preset warn- ing level is exceeded. A green light shows when the power is on and an amber light indicates filament failure in any one of the detectors.

MARBLE TILES

Philippine marble tiles in a wide range of colours and in a new 'thin tile' form are now being offered by Marblecraft, Inc., JMT Building, Makati. The tiles are in. thick, in sizes of 12in. x 12in., 8 x 8, 6 x 12 and 8 x 16in.

Called Martiles, the new tiles are suitable for elegant bathrooms and floors. Their cost is approximately P35 a sq. metre, compared with P80 to 120 a sq. metre for marble slabs.
