Title: Self propelled life saving equipment - has float to pull survivor and controlled pump to remove water from lungs
IPC: B63C9/00
Filed: 1974-10-18
Abstract: The life saving equipment has a float (1) under which is fitted a self contained propulsion unit (2) in a waterproof casing.

Title: Antifreeze compsns. for fuels contg. added water - comprising mixts. of water, glycerol and ether
IPC: C10L1/18
Filed: 1974-11-04
Abstract: Antifreeze compsns. for use in fuels contg. added H2O and sulphonated cpds., comprise mixts. of H2O, glycerol and an ether (ethyl, isopropyl, etc.). The ether component allows the amt. of glycerol used to be reduced and increase the Reid vapour pressure of the product, thereby improving cold-start performance. The fuel can be gasoline, kerosene, gas oil, domestic fuel oil, No. 1 or 2 fuel oil, alcohol (EtOH, MeOH, etc.), or mixts. thereof. The amt. of glycerol used depends on the temp. to be encountered (e.g. 30% for -10 degrees C, 46% for -20 degrees C, 66.7% for -46.5 degrees C). The amt. of ether used is determined by its solubility limit in H2O. The H2O/glycerol/ether mixts. are miscible with hydrocarbons in the presence of sulphonated fatty materials and are soluble in alcohol with or without added fatty material (sulphonated or not).

Title: Regulating the working of a torch burning hydrocarbons - using a selective infrared radiation pyrometer and a thermistor
Inventor: GROUT MICHEL
IPC: F23L7/00
Filed: 1975-03-21
Abstract: The functioning of a torch burning waste gases including hydrocarbons, is improved by an automatic control system for injecting steam into the feed line for the combustible gas. According to the control system, a range of radiation from the flame is selected together with a value of the luminance of this radiation; the luminance value selected being at a level below that corresp. to the appearance of black smoke. The radiation is detected continuously by a device putting out an electrical signal which is a function of the luminance of the radiation, and the signal is used for the automatic control of the injection of steam in amts. which maintain the luminance of the radiation at the value selected. Make full use of the automatic variable feeders available for maintaining constantly the ratio between the feed of the steam and the effective hydrocarbon content of the waste gases delivered. The frequent manual adjustments previously necessary are replaced by automated operation. The consumption of steam is reduced and the accidental emission of black smoke is prevented.

Title: Machining tyre tread moulds by spark erosion - for modifying moulds without causing adjacent damage
IPC: B29C33/42
Filed: 1975-05-07
Abstract: Machining cuts or recessed in tyre mould surfaces, esp. in lamellar inserts for defining small tread channels, involving the use of spark erosion. The method is for coating or modifying tread mould patterns in groups of prefabricated mould shells for defining the tread surface detail, esp. by making cuts of similar dimensions to lamellar widths. Spark erosion machining is localised, does not generate shock waves which could weaken or loosen lamellar mould inserts, and does not generate residual dust or swarf which must be removed from adjacent recesses in the mould tool.

Title: Cooling circuit for vehicle engine - has small separate degassing and expansion tanks with relief valve
IPC: F01P11/02
Filed: 1975-05-26
Abstract: The car engine (1) is cooled by the radiator (2) and is connected to it by pipes (3, 4). The water circulation is maintained by the pump (5). Any gases which are forced out of solution from the: water as the temperature rises flow along the pipe (22) into the de-gassing tank (7). The gases then flow out of the tank (7) along the pipe (14) into the expansion tank (8) and out through the relief valve (27). When the water expands due to heat, it also flows through the de-gassing tank (7) into the expansion tank (8) but returns to the radiator (2) when it cools. The use of separate de-gassing and expansion tanks considerably reduces the sizes of the tanks.

Inventor: OXLEY JOSEPH HUBBERD
IPC: C07C1/00
Filed: 1976-06-17
Abstract: Solid carbonaceous fuels (coal or coke) are converted into synthetic fuels by (a) mixing particles of the solid fuel with an aq. soln. contg. at least one catalytically active cation; (b) heating the mixt. under high pressure at 125-375 degrees C for a time sufficient to modify the structure of the particles and impregnate them with the cation(s); and (c) reacting the particles with one or more of H2, H2O, steam, O2, air, CO, CO2 and organic solvents at a manometric pressure of >10.5 kg/mc2 and a temp. at least equal to the impregnation temp. The process esp. applies to the prodn. of synthesis gas or synthetic natural gas (SNG).
