Title: Improvements in or relating to the cross-linking of polymers
Inventor: CLABBURN ROBIN JAMES THOMAS
IPC: C08K5/00
Filed: 1964-02-06
Abstract: Homopolymers (other than polyethylacrylate and polybutylacrylate) and copolymers at least some of the monomeric units of which polymers contain a C­N or C=O group, the latter preferably being part of a <FORM:1099492/C3/1> group where X is an electron-attracting atom or radical (e.g. an O atom), and which also contain on a carbon atom a labile hydrogen atom which is activated by the C­N or C=O group, are cross-linked by treating the polymer in substantially anhydrous conditions with a basic reacting agent, which yields a monovalent cation, so as to effect cross-linking at the said carbon atom. Suitable basic agents include potassium ethoxide, sodium ethoxide, sodamide, triphenylmethyl sodium and potassium hydroxide. Polymers specified are ethylene/ethyl acrylate copolymer, polyvinyl chloride/ethyl acrylate graft copolymer, polyvinyl chloride/butyl acrylate graft copolymer and polyvinyl chloride/butadiene/acrylonitrile graft copolymer. In some cases, the ethylene/ethyl acrylate copolymer is compounded with carbon black. The polymer or copolymer may be admixed with other polymers or copolymers.  The cross-linked polymers may be used for forming sheets, heat shrinkable films, elastic memory products, insulation for wires and cables, and hot water pipes.

Filed: 1937-02-24
Abstract: 482,981. Lubricating. WELLCOME, H. Feb. 24, 1937, No. 5584. Convention date, Feb. 24, 1936. [Class 12 (iii)] Engines, pumps, or the like are lubricated at intervals by powdered graphite carried in a detachable container 43. A source of air pressure, independent of the apparatus lubricated, is connected at 30 to the head 44 of the container 43. Some of the air passes through a pipe 31 picks up graphite and carries it to ducts 40 in the engine leading to the bearings to be lubricated. The crank shaft may be grooved to distribute the lubricant. A duct may deliver a stream of graphite into the cylinder. As shown for an internalcombustion engine and outlet 50 leads to the carburetter air inlet and has a screen 51 to permit the passage of fine graphite particles. The connecting pipes at 46, 45, 41 and 42 may be valved. The Specification as open to inspection under Sect. 91 describes also an internalcombustion engine in which the crank-case forms a reservoir for graphite. A stream of air is drawn partly through a screened inlet and partly through the reservoir by an air pump and is delivered to a three-way valve. The latter is operated, manually or automatically, to allow graphite laden air to pass either to the engine bearings or to the chassis bearings of the vehicle. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to fuel systems for gas-turbine engines
Inventor: DAVIES DAVID OMRI
IPC: F02C7/236
Filed: 1953-02-27
Abstract: 743,859. Gas turbine plant. ROLLS-ROYCE, Ltd. Feb. 22, 1954 [Feb. 27, 1953], No, 5645/53 Class 110(3) In a fuel system for a gas turbine engine, a centrifugal pump delivers fuel to fuel injectors in combustion equipment connected between a compressor and a turbine, the centrifugal pump being driven by an air motor which is supplied with air compressed by the compressor, and an engine-driven positive-displacement pump delivers fuel to the same combustion space as the centrifugal pump. In the jet-propulsion engine shown, a cetrifugai pump 18 and a gear pump 25 draw fuel from, preferably, the same source, such as a tank 21 by way, it may be, of a booster pump 22. The pumps discharge to a manifold 23 supplying fuel injectors 12. Pump 18, which may have a single-sided impeller as described in Specification 709.002, is driven by an air turbine 31, which receives air through a pipe 34 from the discharge 32 of the compressor 10 of the engine or, as shown at 134, from an intermediate stage of the compressor or. as shown at 234, from the air casing of the combustion equipment 11. Pump 25 is driven from the engine shaft 17 through a connection 33. Since the pressure of the air supply to the air turbine 31 is, for a given engine speed proportional to the intake pressure of the compressor 10, the pumo 18 is automatically driven at a speed at which its fuel delivery is approximately equal to the engine demand. The gear pump 25, compensates for the too low delivery of the centrifugal pump 18 at low engine speeds, back flow through the pump 18 at low engine speeds from the pump 25 being prevented by a non-return valve 28. Pump 25 has a non-return valve 36 and a relief valve 38 which keeps its pressure constant. Coupled shut-off cocks 39 are provided. A throttle 24 controlling by means 24a which may be as described in Specification 693,429 regulates the supply of fuel to the injectors 12. The throttle may be in the air supply pipe 34 instead. In modifications, the non-return valves are omitted, and the pumps 18 and 25 supply separate fuel injectors. or separate concentric chambers of fuel iniectors, such as those described in Specifications 645,696 and 645,908 [both in Group XI].

Title: Processing and or distributing television signals
IPC: H04N5/91
Filed: 1971-03-04
Abstract: 1356193 Television BRITISH BROADCASTING CORP 14 March 1972 [4 March 1971] 6045/71 Heading H4F An initial step in the processing and/or distributing of a television signal comprises removing the blanking periods from the television signal and "time-stretching" the vision signal periods to take up the time previously occupied by the blanking periods. Frame and/or line blanking periods may be removed, information signals indicative of the timing of the vision signal periods preferably being inserted. The result comprises a reduction in bandwidth when the signal is in analogue form or in the bit rate when in digital form. The above step may be effected using a plurality of storage device, e.g. "bucketbrigade" devices or shift registers, the television signal being applied thereto and read-out therefrom by controlled switches. Alternatively a variable delay device may be used, its delay being gradually increased to stretch the vision signal periods and then suddenly reduced so that the blanking periods are omitted, or a video-tape recorder may be used in which recording is stopped during each blanking period. The blanking periods together with appropriate synchronizing signals may be reinserted into the video signal with the aid of the above storage devices and the information signals, which may comprise signals indicating the timing of the leading edges of the line synchronizing pulses, the phasing of the colour bursts, and the odd and even fields. Reference is included to Specification 1,355,648.

[Also in Group XXXVII] An electric vulcanizer comprises a pivoted arm 5 carrying a heating plate 13 which has (a) a main electrical resistance 16 which is switched off permanently when the plate 13 reaches a predetermined temperature and (b) a "holding" resistance which maintains that temperature and is switched off permanently only when the arm 5 is swung up to remove the work. The two heating resistances are connected in parallel, a bimetallically-operated "cycling" switch 35, 41, 40 being connected in series with the holding resistance. The apparatus operates as follows: When the plate 13 reaches its operating temperature a rod 33 in contact therewith melts to release a lever 31 held by the rod 33 in a forked projection 32 on the plate 13 and hence allow a spring 30 to rock an arm 24 about a support 23 to open contacts 25, 26, Fig. 1, or actuate a mercury switch 34 Fig. 2. Resistance 16 is now de-energized. Contacts 40, 41, controlled by bimetal 35, keep the holding resistance "cycling" until the arm 5 is swung about the pivot 4 to actuate a mercury switch 47 and break that circuit. The resistance. 16 comprises a broad. strip arranged round the periphery of the plate 13, the holding resistance and the bimetal 35 being placed side-by-side in the centre of the plate. Bolts 15 and nuts 21 secure an asbestos sheet 18 and a pressure plate 19 over the resistances, an insulating plate 22 overlying all. The switches are positioned above this heating member within a housing 14 supported by a threaded spindle 10 from the arm 5.
