THE accompanying illustration shows a Mercedes-Benz 6-7-ton Diesel engined lorry recently supplied to Messrs. Cadman and Ridge through the Brunswick Garage, Ltd., a concern in Derby.
A point of particular interest is that Mr. A. W. Gaedertz, general manager of British MercedesBenz, Ltd., left the Embankment, London, on his car of the same make at 8 a.m. one morning, collected the lorry from the bodybuilders, near Sandbach, Cheshire, and was back in London with the vehicle at 7.55 p.m. the same day, as fresh as if he had driven back in his own car. Mr. Gaedertz is well known in the private-car world as the manager of the Mercedes Benz racing teams in England and Ireland, which met with much success.
MUCH is heard from Ireland concerning the Drumm storage battery, but, so far, it appears to have attracted very little attention elsewhere; yet, according to the claims which are made, it would -seem to have remarkable properties.
ciS Each cell is said to have a considerably higher voltage than any other type, whilst the normal discharge and charging rates are, respectively, four times and twice those of other cells, and, if necessary, the discharge rate can be trebled for acceleration.
The Drumm cell is of the alkaline type with positive plates built up of oxides of nickel, a special electrolyte which contains dissolved zinc oxide, and nickel negatives which become coated with metallic zinc during charging.
IN connection with the publication of our manual, "Compression Ignition Engines for Road Vehicles," it is of interest to mention that during the past few days many orders for this book have been received from nearly a score of foreign countries, including France, Germany, Holland, Spain, Sweden and Belgium, and from places as far distant from each other as America and the Straits Settlements, and Norway and South Africa. Our circulation is world-wide, OPERATORS of express coaches who, in the forth coming summer season, will convey thousands of holiday-makers to and from the coast would find an inexpensive method of obtaining useful publicity if they adopted attractively displayed pictorial labels for passengers' luggage. Such labels have been used by English and foreign air lines for several years and have always aroused interest. As a matter of fact the Great Western Railway Co. is extending its policy in regard to pictorial labels, and coach operators ought to be fully up to date in matters of this kind.
A TRADE dinner at which Mr. Pybus spoke recently was that of the Electrical Contractors' Association, when he gave some interesting figures regarding the remarkable growth of electrical generation and distribution. The output of electrical energy is increasing at the rate of between five and seven hundred million units per year, and in the past 10 years the sales in this country have almost trebled.
IN many factories and other buildings there is a considerable amount of steel work which must be protected from the elements. Bitumen paint is an excellent medium for this purpose, but it presents the disadvantage of being subject to disintegration under the actinic action of sunlight. By mixing aluminium powder with the bitumen this trouble is overcome and a durable and bright metallic finish results. It is also considerably cheaper than aluminium paint. Made up with a varnish media, it is particularly useful for outdoor tanks, pipelines and the protection of galvanized iron.
