Title: Drying apparatus
IPC: D21G9/00
Filed: 1973-05-10
Abstract: 1430108 Drying webs J & R WALKER PTY Ltd 10 May 1973 [30 May 1972] 22315/73 Heading F4G A drying apparatus comprises a housing 10, rollers 13, 14 each presenting a continuous cylindrical surface, i.e. one which is imperforate and free of protuberances and located within the housing for supporting a length of material, such as paper or board web 20, transported through the housing. There are means to introduce material to be dried into the housing and to guide the material to overlie at least a portion of the rollers while permitting the material during a substantial part of its travel over the rollers, to float on a vapour layer surrounding the rollers and out of direct contact with the rollers, and means for applying heat to the rollers sufficient to vaporize moisture contained within the material to be dried and to create a layer of vapour between the material and the portion of the periphery of the rollers which would otherwise be contacted at any given time by the material while wet. As shown, a feed roll 16 is located within the housing adjacent the inlet 11, and a spring-loaded tension roll 17 positioned at the exit end 12 of the housing maintains a constant tension in the web 20 and endless laterally spaced, driving wires 18 passing around the rolls 16, 17, rollers 13, 14 and wire tensioning rolls 19 are driven by a motor drive unit 21. Burners 22, fed with coal gas or liquid petroleum gas and located in combustion zones 23, 24, are orientated to direct a combustion flame against or towards the periphery of the rollers 13, 14 and hot air is transferred by blowers 29 through ducts 26 into hoods 27, 28; the temperature of the air is detected by sensors 30 and temperature control is effected by regulating gas flow to the burners and by admission of external, pre-heated air via conduits 31. Moisture laden air is extracted from the housing through a duct 32 and by a blower 33 and the hot humid gases expelled may be used to pre-heat air entering the conduits 31; alternatively, the air is removed at a number of spaced points adjacent each of the rollers 13, 14.

Abstract: 1508996 Hot gas engines AUTOMOTIVE PRODUCTS Ltd 15 May 1975 [20 May 1974] 22347/74 Heading F1S [Also in Division F4] In a power-plant including one or more hot gas engines 1, 2 the combustion means 42 and the cooling means 31, 32 of the engine or of one of the engines are inter-connected by conduit means 41 for conveying fluid from those cooling means to the combustion means for participating in combustion in the combustion means, fluid so conveyed having been used as cooling fluid in these cooling means and having had its physical state changed by heat which it absorbed in those cooling means and which had been extracted from working fluid in the second working fluid space 25, 26 of the engine of which those cooling means form part and the combustion means 42 are associated with the heating means 29, 30 of the engine or at least a first of the engines so that when the power-plant is in operation heat generated in the combustion means is supplied to the heating means for heating working fluid in the first working fluid space 23, 24 of the engine or of each of the engines of which the heating means forms a part. As shown the fluid conveyed to the combustion means through the conduit 41 is hydrogen from a tank 38 containing liquid hydrogen 37. The fuel employed may be propane or butane. In a modification (not shown) liquid oxygen is employed for cooling one of the hot gas engines and the oxygen is vapourized by heat exchange with the cooling water and then fed to the combustion means 42. In another modification (not shown) the heater of one hot gas engine is heated by solar energy. Alternatively it is stated that river water may be used instead of fluid heated by solar energy for supply to the engine heater.

Title: Two way communication system
IPC: H04B7/005
Filed: 1958-07-11
Abstract: 889,956. Radio frequency systems. STANDARD TELEPHONES & CABLES Ltd. July 11, 1958 [July 12, 1957], No. 22389/58. Class 40(5). In a system for controlling the receiver bandwidth and the transmitted frequency deviation in a pair of transceivers forming a two - way communication system, first and second control signals f 1 , f 2  and f 3 , f 4  for each direction of transmission provide an indication of the level of signals received and of the frequency deviation of the transmitted signals respectively, and means are provided in the receivers for separating the two control signals and applying them to vary the frequency deviation of the transmitter and to adjust the receiver bandwidth, corresponding adjustments being made at either end of the system. An F.M. signal from the local transceiver, comprising pilot tone f 1 , f 2  and intelligence, is received by aerial 12 of the distant transceiver and fed to filters 17, 16, 18 which separate the respective signal components; the pilot tones f 1 , f 2  being fed to respective detectors 23, 19 and thence respectively to vary the frequency-deviation of the F.M. signal to be transmitted by the distant transceiver, and comprising pilot tones f 4 , f 3  and intelligence, and to vary the bandwidth of the receiver 12; the amplitude of pilot tone f3 being varied in accordance with the level of f 1  to provide an indication of the modulation of the transmitted signals. The amplitude of pilot tone f 4  is varied in accordance with the level of the received signal by means of signal level generator 14. Similarly, in the local transceiver pilot tones f 1 , f 2  analogous to f 4 , f 3  are generated; and the modulation and bandwidth of the local transceiver are varied in accordance with the respective magnitudes of the received pilot tones f 4 , f 3 . In a modification, the indicator 14 samples the amplitude of pilot tone f 2  and varies f 4  accordingly, so that failure of f 2  will cause f 4  to adjust the local transceiver for small frequency deviation transmission, and failure of f 4  will have the same effect. The signal level indicator of the local transceiver may operate analogously with respect to f 3  and f 1 , thereby providing a "fail-safe" control system.

Title: Improvements in or relating to copper coated with silicone resins
IPC: B05D3/10
Filed: 1953-08-17
Abstract: A silico-alkyd resin, suitable as an insulation for copper wire conductors which are oxidized to improve the adhesion between wire and resin, is prepared by condensing 548 grams of a silane mixture, containing 70 mol. per cent of C6H5 CH3Si(OC2H5)2 and 30 mol per cent of C6H5 Si(OC2H5)3, with 1058 grams of anhydrous glycerine and 850 grams of phthalic anhydride.ALSO:Silicone resins are caused to adhere strongly to copper by first forming a strongly adherent film of cupric oxide thereon, then coating the blackened copper with a silicone resin, and finally heating the coated copper to bond the resin to it.  The oxide coating may be formed by the action of aqueous solutions of sodium, potassium or ammonium persulphate together with sodium or potassium hydroxide or with hot solutions of sodium or potassium hydroxide and sodium or potassium chlorate as in United States Specification 2364993, and the silicone resins may be "straight" resins or alkyd-, melamine-, alkyd melamine-, or epoxide-modified silicone resins applied by dipping, brushing, or spraying followed by heating to remove solvent and cure the resin. Preferably the oxide coating on a copper wire is formed by passing the wire first through an oxideremoving bath containing nitric and sulphuric acids with a smaller amount of hydrochloric acid and then through an oxidizing bath containing sodium chlorite, sodium chloride and caustic soda.  The oxide-bearing copper wire is then coated by passage through a solution of a silicoalkyd resin prepared by condensing a silane mixture with anhydrous glycerine and phthalic anhydride.ALSO:Preparatory to bonding a silicone resin to copper, especially a wire, the copper is cleaned to remove oxide in an aqueous bath consisting of nitric, sulphuric, and hydrochloric acids and is then passed through a boiling aqueous oxidising bath consisting of sodium chlorite, sodium hydroxide, and sodium chloride to produce an adherent flexible black oxide coating on the copper which assists bonding of the resin to it.  Reference is also made to oxidizing the copper with solutions of sodium, potassium, or ammonium persulphate together with sodium or potassium hydroxide or with hot solutions of sodium or potassium hydroxide and sodium or potassium chlorite as in U.S.A. Specification 2,364,993.
