This Rings a Bell
pSTABLISHED. to buy the patent rights of the American registering ticket punch, which had been adopted by certain tramway companies in Britain, the Bell Punch Co., Ltd., had their eightieth birthday last July. The London General Omnibus Co., Ltd., began experimenting with this punch in r891, and eventually used it on all their routes. Since then the Bell concern have developed many instruments for ticket issuing, including the well-known Ultimate, and they claim to be the largest ticket printers in the world, with their own paper mill-at Wraysbury.
Until about 1930 the taxicab trade was dependent upon imported taximeters. However, the Bell Punch Co. took the production of these in their stride and are believed to be now the only manufacturers here of these meters. Adding and calculating machines later took their places in the production line, also receipting instruments for garages and the like.
In the manufacture of these machines and punches, much use is made of the Bonderizing pretreatment for steel parts which are to be painted, and the Pyturnin Process for bonding paint to the aluminium castings which are so much employed, whilst Parkerizing protects those of Unpainted steel against rust.

Strong But Light Steel
ASTEEL alloyed with aluminium. and, manganese
developed in America is said to be 15 per cent. lighter than carbon or stainless steel and up to 25 per cent. below the weight of alloys of cobalt or nickel, whilst having a strength-to-weight ratio higher than most of today's metals.
Change of Oil Not Dangerous
NAANY operators of used vehicles have for long believed "1 that it is unwise, if not 'actually dangerous, to change from a " straight " engine oil to special additive types without thoroughly cleaning the engines concerned. Recently, a lecturer from the Mobil Oil Co., speaking at a meeting of the Southern Centre of the Institute of Road Transport Engineers, stated definitely that this was a misapprehension; that no additive material had yet been found which would remove carbon deposits and cause them to become a danger by possibly blocking oil conduits, or channels, alit-lough they would, of course, help to obviate further "coking," In fact, he added that the oil companies would be very glad if they could find something which would remove hard carbon. Such a statement may relieve the doubts of users who have hesitated to make such ,a change between periods of engine-overhaul.
Bus Map for Rubbernecks
A NEW bus map showing 15 "essential" routes for
visitors has been produced by London Transport. It is of neat pocket size and carries on its cover that somewhat debated phrase, " Hop on a Bus." The purpose is to show those routes which wilt take strangers in London to most of the places of interest in the central parts. For this purpose the map has a lettered and numbered grid and an index covering 37 of • the leading attractions in the West End and City, but actually 72 high spots" are shown. The first printing, in readiness for the tourist season, is of 250,000 copies.
Not so, Asinine
TRADERS in the United Kingdom no doubt think they often have difficult distribution problems. How would they feel, however, if they had to follow the example of an Exide service agent in his efforts to have his batteries delivered to his customers, when transport is limited to the type shown in the accompanying illustration? But it does present several points, donkeys have the advantages of low running costs, need virtually no inspection . and require retuarkably little rgaintenance. Possibly all this could happen only in India, and in this instance the agent is in the Punjab. His battery deliveries often have to be made
by this means when customers are located in comparatively inaccessible districts.
No doubt news concerning other unusual delivery problems, such as by sleigh, elephant or yak will now be brought to the notice of this journal.
