Title: Improvements in and relating to the production of oxygen-containing organic compounds
Inventor: COFFEY ROBERT STEVENSON
IPC: C07C51/235
Filed: 1962-07-02
Abstract: Oxygen-containing organic compounds, including olefine oxides and carboxylic acids, are produced by contacting a liquid mixture containing an aldehyde having 2 or more carbon atoms and an olefinic compound containing at least 4 carbon atoms, the double bond being in a non-terminal position, at a temperature in the range 30-150 DEG C. with an oxygen-containing gas. Suitable aldehydes are, for example, acetaldehyde, propionaldehyde, n-butyraldehyde and benzaldehyde. Suitable olefinic starting materials are, for example, aliphatic mono-olefines such as cis- and trans-butene-2,2,4,4-trimethyl-pentene-2, n-octene-2; cyclo mono-olefines such as cyclohexene; arylalkenes; open-chain and cyclic dienes and polyenes; and acids, alcohols, ketones and esters containing a carbon-carbon double bond which is in a non-terminal position. An inert diluent, for example acetone, methyl acetate, ethyl acetate or acetic acid or the acid that is being produced, may be present.  The process is advantageously carried out in the presence of one or more organic or inorganic salts of metals of variable valency, e.g. copper, manganese, nickel or cobalt, and/or an imitator which is able to yield free radicals during the course of the reaction such as hydrogen peroxide, alkyl hydroperoxides, dialkylperoxides, diacylperoxides, dialkylperoxy dicarbonates, peroxy esters and azo compounds.  The process may also be carried out under the influence of ultra-violet light. Examples are given of the conversion of a mixture of (a) 2,4,4-trimethyl-pentene-2 and n-butyraldehyde to 2,3-epoxy-2,4,4-trimethyl pentene and butyric acid; (b) cis-butene-2 and acetaldehyde to cis- and trans-2,3-epoxybutane and acetic acid; (c) trans-butene-2 and acetaldehyde to cis- and trans-2,3-epoxybutane and acetic acid and (d) cis- and trans-octene-2 and benzaldehyde to epoxyoctanes and acids.

Title: Improvements in mobile means for compacting soil or a cement and soil agglomerate
IPC: E01C19/34
Filed: 1954-09-02
Abstract: 786,068. Percussive tools. MASSEY, Ltd., B. & S., and WELLS, L. W. Dec. 2, 1955 [Sept. 2, 1954; Dec. 2, 1955], No. 25467/54 and 34511/55. Class 124. A mobile machine having falling weights for compacting soil comprises a trip or a row of trips, each secured to one end of a pivotally mounted beam, the other end of which carries a roller engaging a cam on a driven camshaft causing the trip to be raised and the fall under gravity assisted by fluid pressure, cushioning means to compensate for variations in soil consistency, means for holding the trip up at the end of its upward movement, and means preventing the trip from dropping too far in the event of its reaching a hole in the ground. As shown, a shaft 13 mounted in a frame 14 carries a bell crank lever 11 mounted on a long bearing 12, the bell crank carrying at one end 11a a trip 10, and at the other end 11b a cam roller 15 mounted between two plates 22 pivoted at one end at 23 on a shaft passing through arms of the part 11b, the other ends of the plates being attached to one side of rubber blocks 24 the other sides of which are attached to the part 11b. A cam 16 mounted on a driven camshaft 17 co-operates with the roller 15 to move the bell crank lever 11 and raise the trip. A piston 19 is connected to the part 11a of the bell crank and upward movement of the part 11a moves the piston in its cylinder 18 and compresses a fluid therein. On the cam releasing the roller the piston descends and assists in producing the blow delivered by the trip. Should the trip tend to fall below the normal level due to the presence of a hole in the ground, the roller, which, with the trip in its lower position, is normally at a distance of, say, 1 inch from the cam, is prevented from striking and damaging the cam by a pair of rubber cushions 29, 30, mounted on the plates 22 and the part 11b respectively, which hold the roller so that it rests on the circular portion of the cam. The part 11a carries a plate 31 having a slot 32 which may be engaged by a catch 34 on an arm 33 which is spring urged at will to engage in the slot and hold the trip in the raised position or to disengage therefrom. To allow disengagement to take place easily the height at which the trip is held is such that the cam just engages the roller and allows the disengaging spring to move the catch out of the engaging position. The machine may be provided with, say, six trips each having its own cam, roller, bell crank lever, and catch or there may be a single trip extending over the width of the machine and supported at either end by a long bearing. The trip may have an upwardly sloping part at the front of the striking face and a level portion at the rear.

Title: Improvements in or relating to multiplying machines
IPC: G06F7/46
Filed: 1937-09-23
Abstract: 502,618. Calculating - apparatus. BRITISH TABULATING MACHINE CO., Ltd. Sept. 23, 1937, No. 25784. Convention date, Sept. 25, 1936. [Class 106 (i)] A multiplying machine with means adapted to multiply automatically a multiplicand and multiplier to obtain one product and \ ice versa to obtain a second product is provided with comparing mechanism operable automatically to compare the two products and to give a warning if the products do not agree. In a machine provided with recording or punching mechanism the comparing mechanism may operate to prevent the product being punched when the two products under comparison are unequal. The invention is shown applied to a record card controlled machine as described in Specification 405,031. The machine described includes registers MP-1, MP-2, MC-1, and MC-2, Fig. 1, accumulators RH, LH-1, and LH-2, read-out mechanism for each register and accumulator. and the usual card handling section. Fig. 2, punching unit PU, Fig. 1a, relay sections MPR, CS, and CR, cam contacts CC, FC, impulse emitters 22, 23, 23a, and an impulse distributer 24. When the machine is started and a card is fed from the magazine 25, Fig. 2, it is fed, during the second cycle, passed reading brushes 33 and the multiplier and multiplicand are entered directly into the registers MP-1, MC-1, and into the registers MC-2, MP-2. The machine then proceeds to multiply the factors in the first pair of registers and the product is entered into the accumulators RH, and LH-1. The right-hand part in the accumulator RH is then transferred to the accumulator LH-1 to obtain the final product. The accumulator RH is then reset and a second series of multiplying cycles is initiated with the factors obtained from the second pair of registers, and the result finally entered into the accumulator LH-2. All the registers are then reset. By the resetting of the register MC-1 the comparing mechanism is automatically operative to compare the amounts on the accumulators LH-1, LH-2 ; if the amounts agree a new card cycle is initiated and the accumulator LH-1 is reset. If the amounts do not agree the circuit to the card feed clutch magnet 31, Fig. 1a, is not completed, the card is removed and a feed operation is then initiated by hand. When the amounts agree the punching of one column of the product will occur and means are provided to check the punching against the amount standing in each column of the accumulator LH-2. If a hole is wrongly punched further punching is interrupted and the operator is compelled to release the card by depressing the release key of the punching unit. The accumulator LH-2 is thereupon reset. By means of manually operated switches to vary certain of the electrical circuit arrangements the machine may be operated under rate card control.
