ALUMINIUM LEVELLING STAFF
A telescopic, dual-faced levelling staff made of aluminium alloy has combined strength and light weight with efficient operation. The gradua- tions are marked at 80 degrees F (26.7 degrees C), allowing it to be used under most conditions without the need of temperature adjustments. Co- efficient of expansion is 0.000023 per degree C. Both faces can be marked with a selected range of measurements.
Its surface is protected with a tough polyester film. Stainless steel reinforcing plates are fitted to the lower section, giving strength to the shock-proof double plunger system.
The staff is available in 3-piece tele- scopic lengths of 5 m, 4 m, 3 m, 2 m, 16 ft, 14 ft, 12%1⁄2ft, 11ft and 91⁄2ft.
Developed by an Australian firm, Brookeades, the staff has won the "Good Design" award of the Industrial Design Council of Australia. For fur- ther information, please write to Brookeades Pty. Ltd., 10 Boag Road, Morley, Western Australia 6062.

They include a simple double gold border on a white background in the "Gold Line", a gold-on-white "Grecian "Gold Line", a gold-on-white "Grecian Key" pattern (illustrated) and the "Black Gold Line", a double gold border on a black background. All the gold used is 24-carat. All knobs are available with either screwless or Louis XV backplates, gold-plated or floren- tine bronze finish. Special gold-plated key escutcheons are available.
The company also makes a wide range of porcelain knobs with colour- ful peacock, rosebud, sepia, violet and other bird and flower designs. This
range includes fingerplates. The same designs are available on drawer-pulls and triangular cupboard knobs.
Another porcelain product is as- sorted fruit and nuts in convex and triangular cupboard knob sets, designed mainly for use in the kitchen. Each article is treated by a scientific baking process and kiln-fired. This gives the knobs a deep, permanent lustre and the gold and other designs will resist wear, humidity and other climatic con- ditions. Please address inquiries to Perma Trading Co. Pty. Ltd., P.O. Box 11, Hawksburn, Victoria 3142.
WOOD VENEERS
A wide range of natural wood veneers, cut to a variety of standard door sizes so that they can be simply laid on, thus eliminating wastage and considerably reducing door production time, has been introduced by a British firm.
Of particular interest to furniture manufacturers, panellers, cabinet
makers, joiners, shopfitters and other woodworking industries, the new range is produced in Oak, Sapele, Afrormosia, Teak, Walnut, Rio Rose- wood, Cherry, Mahogany, Macassar, Tola and Beech.
The makers maintain a high degree of standardisation and retain the essen- tial characteristics of the natural grain formation. Selected veneers are cut and bonded to form logs; it is these which are then cut to produce the finished product. By this means, not only is consistency of grain and colour ensured, but the veneers are free from common faults such as wild grain, open knots, shakes and open splits, which normally result in costly wast- age.

PATCHING COMPOUND
A chemically-resistant, epoxy resin patching compound for all underwater applications is being marketed by Fosmac Export Ltd., Cleveland Road, Hemel Hempstead, Hertfordshire, U.K.
Known as the "Nitojoint," it is based on solvent-free epoxy resins modified with inert fillers and is a highly effective underwater gap and crack filler. The material, which forms gas and water-tight joints, can also be used to permanently protect submerg ed areas which have spalled due to cor- rosion.
The new patching compound is re- sistant to attack by most inorganic and organic chemicals, including oils, ef- fluent, sewage and other pollution; it may be used in both fresh and sea water.
Nitojoint is extremely simple to mix and apply and has the following physical properties: absorption - neg- ligible, approx. compressive strength - 70MN/m2 (10,000 lb/in2), dry heat resistance up to 60 degrees C, and tensile strength over 9MN/m2 (1,300 lb/in2).

The material has excellent stability in the unmixed stage during storage and, as no solvents are contained in the resin mix, extra ventilation is not required during application to keep working areas free from harmful fumes.
Nitojoint is best applied by trowel or spatula and is available in handy packs containing 2,300 cm3 or indus-
