Title: Process for the manufacture of town gas
Inventor: LOWENSTEIN-LOM WALTER GERALD
IPC: C10J1/213
Filed: 1954-08-06
Abstract: 768,718. Gas manufacture. ESSO RESEARCH & ENGINEERING CO., July 26, 1955 [Aug. 6, 1954], No. 22901/54. Class 55 (2). The calorific value of a combustible gas is increased by mixing the gas with not more than 20 per cent, and preferably not more than 14 per cent, by weight of a vaporized, normally liquid, hydrocarbon having a final boiling point not higher than 240‹ F., and preferably not higher than 180‹ F. and not below 90‹ F. The hydrocarbon is preferably a substantially saturated petroleum hydrocarbon, a light virgin naphtha being mentioned. The mixing may be effected by distilling the required hydrocarbon from a pipe still, which has the condensers maintained at a temperature not exceeding 240‹ F., and to mix the hydrocarbon vapours with the gas. Or the combustible gas may be heated and bubbled through the hydrocarbon liquid, or the hot gas may travel up a packed column down which the liquid hydrocarbon trickles. The gas may be passed over a hot plate on which the hydrocarbon is sprayed. When a low end-point naphtha is used, it may be evaporated completely and the vapours allowed to diffuse into a gas-filled container. In the Figure, coal gas from retorts R is purified at 32 and passes to a benzol-extraction plant 2. The gas may then flow through pipes 3, 4 to the consumer line 6, or through pipe 7 to 8 where it is mixed with the hydrocarbon. The enriched gas then passes to the consumer through lines 9, 16, 10, 6. Producer gas from the producer P is used, in part, to heat the retorts in zone 17, and in part passes through pipe 12 to zone 13 where it is enriched with the hydrocarbon and passes to the consumer through pipes 14, 15, 16, 10, 6. Flue gas from the zone 17 is enriched at 19 and passes to the consumer via pipes 20, 10, 6. Water gas from generator W is enriched at 23 and passes to the consumer via 24, 15, 16, 10, 6. Residual heavy hydrocarbons from the zones 19, 8, 13, 23 are collected and transferred by pipes 25-29 to the zone 24 where they are blended with gas oil for carburetting water gas from line 30 which is then passed to the consumer through pipes 5, 6.

Title: Improvements in and related to a lubrication system
IPC: F01M5/04
Filed: 1946-08-06
Abstract: 649,705. Lubricating systems. MARTIN CO., G. L. Aug. 6, 1946, No..23248. Convention date, Oct. 3, 1942. [Class 12 (iii)] In a lubricating system with an oil reservoir and oil cooler and a thermally-operated control valve to direct the oil to different parts of the cooler or to byepass the same and wherein means are provided for introducing a diluent to reduce the viscosity, such diluent is admitted into the lubricant at a point adjacent the thermal element, The resulting reduction in temperature sets the valve to a " cold " position in which the returning lubricant byepasses the cooler and passes to a " warm up " compartment of the reservoir. The oil tank 2, Fig. 1, with an inner warm-up part 6 is supplied through pipe 10 and valve 5 with oil byepassing or from the cooler 4 which is in an air duct 12, the oil being forced by pump 9 which is driven either by the engine 1 or an independent motor 39.

Patent GB-783784-A (GB)
Title: Aminoalkyl cyclopolysiloxanes and their preparation
IPC: C08G77/26
Filed: 1954-08-11
Abstract: An aminoalkylcyclosiloxane is made by reacting a cyclopolysiloxane, having one chlorine atom attached to silicon through aliphatic carbon, with a compound having the formula HNXX1, in which X is hydrogen or an alkyl or aryl radical and X1 is an alkyl or aryl radical, examples of these radicals being given.  Aminating compounds which are anhydrous and are liquid under the reaction conditions are preferred, though solvents, e.g. benzene, toluene, xylene and liquid saturated aliphatic compounds, may be used.  The chlorinated siloxanes used may be those made by the process of Specification 611,494 and may contain besides the chlorinated hydrocarbon radical silicon bonded hydrogen atoms, alkyl, aryl, cycloaliphatic, hydroxyl, halogen, alkoxy, amine, -NCO or -NCS radicals.  The reaction is desirably conducted using an excess of the amino compound as the reaction medium, although an excess of the amino-compound may be reduced by using an inert diluent. Hydrohalide acceptors, e.g. tributylamine, pyridine and quinoline may be substituted in place of some of the excess amino compound. The reaction may be effected under normal or super-atmospheric pressure and at temperatures ranging from -35 DEG  to 150 DEG  C., with subsequent removal of excess amino compound, treatment with alkali and fractional distillation.  In examples, chloromethylheptamethylcyclotetrasiloxane was (1) refluxed with diethylamine and toluene to yield diethylaminomethylheptamethylcyclotetrasiloxane; (2) refluxed with n-butylamine, freed of excess amine and heated to 150 DEG  C. to yield a solid polymer which was depolymerized at 500 DEG  C. into a liquid composed of siloxane tetramers, pentamers and hexamers containing Si - bonded methyl and n - butyl - aminomethyl radicals; (3) reacted with dimethylamine under pressure at room temperature to give a liquid which on fractionation yielded dimethylaminomethylheptamethylcyclotetrasiloxane; (4) refluxed with aniline and toluene to yield anilinomethylheptamethylcyclotetrasiloxane; (5) refluxed with N-methylaniline and toluene to give N,N-phenylmethylaminomethylheptamethylcyclotetrailoxane; (6) refluxed with diethylamine and iso-octane to give N,N-diethylaminomethylheptamethylcyclotetrasiloxane; (7) refluxed with n-butylamine and iso-octane to give n-butylaminomethylheptamethylcyclotetrasiloxane.  The compounds nay be used as intermediates in making ion-exchange resins or for modifying other organopolysiloxanes.  The arylamino compounds are auto-catalytic and on standing for long periods form linear polymers useful in making silicone rubber.  The aliphatic amino compounds are also useful in making rubbers, resins and oils.  The compounds containing aminomethyl and aminophenyl radicals are particularly suitable in electrical applications where arc-extinguishing properties are required.  Salts of the compounds have surface-active properties.

Title: Improvements in or relating to telephone circuits
IPC: H04M1/715
Filed: 1947-08-25
Abstract: 633,520. Telephone extension circuits. ERICSSON TELEPHONES, Ltd., and GUNSON, G. R. Aug. 25, 1947, No. 23407. [Class 40 (iv)] In a circuit in which a main instrument and an extension instrument are connected to the same two-wire exchange line, the extension subscriber can recall the main instrument by means of a vibratory relay or like device after the exchange line has been switched through to the extension. The main instrument TI, which has the usual bell BM, 'communiates with the exchange in the normal manner through line L1, L2. The subscriber at the main instrument operates key KE to connect the extension instrument TE to the exchange line, and an -indicator relay R then gives visual indication of all extension calls and also short-circuitsbell BM at contact rl so that outgoing calls from the extension do not affect the bell BM. Speech currents follow a low impedance path through a condenser QD. Ringing current from the exchange rings both bell BM and the bell at the extension, but does not produce sufficient voltage to operate relay R or a relay A in a rectifier bridge circuit MRB. To recall the main instrument, the extension subscriber operates a key KN, which has make-beforebreak contacts, thus connecting up a vibratory relay RR whose make-before-break contact rrl is provided with a non-linear resistance SS as a spark suppressor. The vibratory relay RR superimposes upon the direct current in the exchange line an alternating component which is rectified by the rectifier bridge MRB and operates the relay A whose contact al completes a circuit to ring a bell MC in the main instrument. The subscriber at the main instrument may then join in the conversation. The subscriber at the other end of the line is prevented from receiving undue noise during the signalling by a shunt circuit comprising rectifiers MRA and a condenser QB.
