Title: Improvements in or relating to belt conveyors
Inventor: THOMSON CHARLES
IPC: B65G23/00
Filed: 1964-03-18
Abstract: 1,106,341. Endless conveyers. SOLAR THOMSON ENGINEERING CO. Ltd. 17 March, 1965 [18 March, 1964; 19 June, 1964], Nos. 11518/64 and 25579/64. Heading B8A. An endless conveyer belt 17 wraps, and is driven by frictional engagement with, a plurality of separately driven sections of an endless driving belt 10, each section having a driving belt tension sensitive device 16 which depending on the loading on the conveyer, controls the motor drive to the drive pulley 11 of the drive belt section. The driving belt 10 is passed around pulleys 11 and 15 at each end of each driving section. The downstream pulley 11 of each section is driven from a motor 12 through fluid coupling 13, brake mechanism 14 and gear-box 14a. The tension sensitive device 16 comprises the pulley 15 whose shaft is carried by a pair of arms 21 which are pivoted at 22 to the supporting framework. The arms are sprung into the horizontal position by springs 25, and pivoting motion thereof is damped by dashpots 24. With overtension of a particular drive belt section the associated arm 21 pivots to contact a switch 26 which through a control motor 27 reduces the transmitting power of the fluid coupling 13 associated with the next downstream drive belt section motor and vice versa with undertension, the belt tension being thereby maintained at a predetermined value. The brake mechanism 14 is variably operated in conjunction with its associated fluid coupling. In a further embodiment, Figs. 7, 8 (not shown), the tension sensitive device, which comprises a spring biased pivoted lever mounting a pulley, has its lever linked directly to a fluid coupling of the adjacent upstream drive belt section motor, to effect varying transmission power thereof.

Title: Improvements in or relating to method for the preparation of aryl substituted primary alcohols
Filed: 1951-05-23
Abstract: Aryl substituted primary alcohols are obtained by the reduction and splitting of the ring of 4-aryl-1 : 3 dioxanes, which are formed by the action of formaldehyde with styrene or substituted styrenes. Customary methods for the reduction with hydrogen over catalysts are employed.  In examples, 4-phenyl-1 : 3-dioxane obtainable by the action of aqueous formaldehyde and sulphuric acid on styrene, is treated under pressure with hydrogen and a catalyst under various conditions to give 3-phenylpropanol. Numerous phenyl and naphthyl-1 : 3 dioxanes, substituted by alkyl or phenyl groups in the 5- and/or 6-positions, are also specified as suitable for reduction to the alcohols.  The alcohols give esters with aliphatic and aromatic dibasic acids such as adipic or phthalic, which are useful for compounding with vinyl resins.

Filed: 1929-04-18
Abstract: 332,285. Forwood, G. F., Taplay, J. G., and United Kingdom Oil Co., Ltd. April 18, 1929. Hydrocarbons, cracking.-Oils are cracked by passing them in the vapour phase under low pressure mixed with steam through a conversion chamber containing a heated catalyst consisting of a porous vegetable charcoal impregnated with sodium aluminium silicate. The conversion chamber is kept under a pressure of 30-10 lbs. per sq. inch and is heated to 450-650‹ C. The catalyst is prepared by treating wood charcoal or equivalent calcined cellulose structure of great porosity with a previously boiled mixture of kaolin, water and sodium silicate the charcoal being immersed in the liquid, the mixture boiled and the excess liquid run off. Alternatively the catalyst is prepared by mixing charcoal with 5 per cent of sodium aluminium silicate until a greyish mixture is obtained. Crude oil from a tank 1 is passed through a preheating coil 3 forming a baffle in a separator 4 and is then vapourized in a coil 3<a> in a furnace 5. The vapours are injected by a steam injector 6 having an extension pipe 7 into the catalyst chamber 8 comprising an in clined steel pressure vessel provided with longitudinal fire tubes 12 supplied continuously or intermittently with the catalyst from a hopper 19 and conveyor 20. The products pass through a pipe 22 provided with a reduction valve 23 into the pressure reduction chamber 4 from which the vapours and gases pass off through a pipe 27 and condenser 28, the condensate being collected in a receiver 29 while the gases are led to a holder 30 from which they are passed to a burner 11. The gases may be purified by passage through an oil scrubbler 32 or a purifier containing silica gel &c.
