Local authorities have appointed a total of 1,250 delegates to the Congress and Exhibition, which will remain open until July 26. The doors will be open from 10.30 a.m. until 6.30 p.m. each day, and the cost of admission is 2s Many important papers will be submitted to delegates, and reviews of those of special interest to readers of The Commercial Motor" will be published next week. Exhibits related to transport are dealt with in these pages, and include a new 20-ton dump truck and several refuse collectors of recent introduction.
Apart from the exhibits reviewed, road materials will be seen on many stands, and the British Road Federation will stage an exhibition of modern road-building technique. "The Commercial Motor" will be found on Stand 106 of Temple Press Ltd., where visitors will be welcomed.
The new dumper, of 13 cubic yd. capacity, will be shown on Stand 52 by John Blackwood Hodge and Co., Ltd„ Hunsbury Works, Northampton. It comprises a four-wheeled tractor with a General Motors model 6/71 150 b.h.p. oil engine, and a two-wheeled semi-trailer with full-length "bomb doors," through which the load can be discharged. The speed range of the vehicle when laden is said to be from 2.5 m.p.h. to 26 m.p.h. The hopper is wedge shaped and is designed to distribute a large part of the payload over the driven axle. The bottom doors are opened by gravity and closed by pneumatic power.
By way of contrast, lighting fittings of many kinds, including the special Mazdalux equipment for fluorescent lighting in public-service vehicles, will be seen on Stand 5 of the British Thomson-Houston Co., Ltd., Watford.
The need for economizing in manpower has caused close attention to be focused on mechanical handling. One of the most useful items of equipment for this purpose is the fork truck, of which an example will be shown on Stand 18 by Coventry Climax Engines, Ltd., Coventry. The truck is capable of lifting a load of 4,000,1b. to a height of 12 ft., by hydraulic power, and of travelling at speeds up to 91m.p.h., either forward or in reverse.

Probably the most interesting exhibit of Dennis Bros., Ltd., Guildford, will be the new H.R.C. refuse collector, which was seen for the first time at the Public Cleansing Conference at Blackpool. It was described and illustrated in "The Commercial Motor" of June 20, and the outstanding feature of its design is the use of a
hinged rear hopper, which is raised when tipping • to allow the unobstructed passage of refuse. Compression gear enables 16-18 cubic yds. of refuse to be carried.

There are also to be two refuse collectors, one a 11-12 cubic-yd. side-loading Derby type based on an Austin 5-ton long-wheelbase chassis, and the other a 7 cubic-yd. outfit with a Morris-Commercial CVS11/40 chassis. Metal sliding covers in three sections are fitted on each side. The fifth exhibit will be a trailer road sweeper, suitable for towing by a tractor or vehicle.
Except for a 25-ft. three-stage tower wagon based on the Thames 2-ton chassis, the exhibits of the Ford Motor Co., Ltd., Dagenham (Stand 36), will be similar to those seen at Blackpool. They will comprise a Thames 3-ton 7 cubic-yd. refuse collector, a• Thames 5-ton Derby-type 12 cubic-yd. refuse collector, and a Thames 4-ton 500-gallon combined gullyand cesspoolemptier.

Glover, Webb and Liversidge, Ltd., 561, Oki Kent Road, London, S.E.1, intends to repeat the outstanding success that it scored at the Public Cleansing Conference at Blackpool with the new chassisless 12-cubic-yd.
refuse collector. This is entirely different from any refuse vehicle that has been produced in this country before. It has front-wheel drive, and the Meadows engine and gearbox, transmission, etc., are mounted on a sub-frame. The Transport power-driven moving floor serves as a basis for the body. Another advanced feature is the independent suspension system. (Stand 50.)

The Transport moving platform is fitted to the CK3 15-cubic-yd. refuse collector, which also has a six-seater cab. The fourth refuse collector to be shown will be the Karrier-Yorkshire 15-cubic-yd. mechanical loader, in which hydraulic power is used to raise the bins to the top of the vehicle for the discharge of refuse.
