Patent GB-1266415-A (GB)
IPC: F15C1/00
Filed: 1969-03-07
Abstract: 1,266,415. Fluidic governors. BENDIX CORP. March 7, 1969 [March 14, 1968], No. 12192/69. Heading G3P. [Also in Division F1]  An engine speed governor has a fuel valve 32 positioned by piston 34 under control by a flapper 54 connected to a diaphragm 64 responsive to pressure Px in chamber 66 which varies stepwise at a frequency proportional to the speed error. Flapper 82 established a feedback pressure acting on diaphragm 62. As shown, a two-phase sinusoidal output from switch 166a driven by selfexciting reference frequency oscillator 132 is converted by bi-stable switches 156a-c into a four-phase squarewave signal whose pulse trains A-D are fed to switches 166b-e where they oppose pulse trains from engine-driven pulse generator 108. Pulse trains A, B are 180 degrees out of phase with each other and 90 degrees out of phase with pulse trains C, D which, in turn, are 180 degrees out of phase. The pulse trains A<SP>1</SP>-D<SP>1</SP> obtained at the centre outlets of switches 166b-e have a frequency equal to the beat frequency of the reference pulses and the engine speed generated pulses and are applied in pairs to bi-stable switches 156d, e. The outputs A<SP>11</SP>-D<SP>11</SP> of switches 156d-e are applied to self-switching monostable switches 140a-d having capacitive delays 240, 242, 250, 256. The brief duration outputs A<SP>111</SP>-D<SP>111</SP> of switches 140a-d are applied to the control ports of monostable switches 140e-l whose power jets derive from outputs A<SP>11</SP>-D<SP>11</SP>. During underspeed conditions, the outputs A<SP>11</SP>-D<SP>11</SP> follow a first distinct sequence and the outputs from switches 14Oi-l arrive at OR-NOR switch 174b causing the latter to direct pulses at four times the beat frequency to chamber 66 via check-valve 96. During overspeed conditions, the outputs A<SP>11</SP>-D<SP>11</SP> follow a second distinct sequence and the outputs from switches 140e-h arrive at OR-NOR switch 174a causing the latter to effect step-wise lowering of the pressure in chamber 66 via check-valve 98 at four times the beat frequency. When the speed error increases to the point where the beat period equals the duration of outputs A<SP>111</SP>-D<SP>111</SP> switch 174 a or b provides continuous variation of P x . Switch 140m provides an analog pressure in chamber 68 proportional to engine speed to improve transient response. In a modification Fig. 2 (not shown) the enginedriven pulse generator provides a four-phase squarewave signal whose pulse trains are each compared with a reference frequency in switches 166b-e as above. The roles of switches 174a, b are reversed. The valve 32 could control steam or gas supply to an engine; alternatively, piston 34 could control the engine load.

Abstract: 1304340 Carbon and graphite filaments CELANESE CORP 15 June 1971 27914/71 Heading C1A Continuous lengths of carbonized filamentary material are produced by first stabilizing, i.e. heating at least in part in an oxygen containing atmosphere, whilst retaining the filamentary structure until the filaments are non-combustible in a match flame, continuous filaments of acrylonitrile, either as a homopolymer or a copolymer, and then passing the stabilized filaments continuously into and through a heater which has an inlet temperature not higher than 650‹ C. and a zone where the temperature rises from 900‹ to 1600‹ C. in the direction of travel of the filament or filaments, the feed rate of the material to the heater being such that it reaches said zone in from 3 sees. to 10 mins., and passes through said zone in from 3 sees. to 5 mins. Preferably the material reaches the zone in from 3 sees. to 5 mins. and passes through that part having a temperature of from 1400‹ to 1600‹ C. in from 3 to 70 seconds. The carbonization is preferably performed in an atmos. of nitrogen. The carbonized filaments may subsequently be graphitized by heating at 2400‹ to 3100‹ C. in an inert atmosphere. The graphitization may be effected by passing through a zone in which the filament is heated to 2700‹ to 3000‹ C. in from 30 sees. to 2 mins. If desired, the process may be completed in a heater having two zones, the first having a temperature rising from 900- 1600‹ C. and the second from 2700‹ to at least 2900‹ C., the material travelling from the low to the high temperature zone in from 2-30 secs.

Abstract: 1308828 Copolyamides; curing epoxy resins VICTOR WOLF Ltd 28 May 1971 [5 June 1970] 27135/70 Headings C3B and C3R Copolyamides are obtained by condensing a polyamine with a dimerized fatty acid and phenylindane dicarboxylic acid in the presence of a monocarboxylic acid, the dimer acid providing the major proportion of the carboxyl groups. Various diamines are specified as the polyamine, diaminoalkanes being preferred. Minor proportions of aromatic, cycloaliphatic and polyalkylene polyamines may also be used, e.g. phenylene, xylylene or isophorone diamine or diethylene triamine. The dimer acids may be hydrogenated. Specified monocarboxylic acids include C 2-22  aliphatic acids, aromatic acids and hydroxy acids. The products are stated to have good solubility in propanol with reduced tendency to gel and be suitable for flexographic and gravure inks or coating compositions. If excess diamine and triamine is used reactive polyamides useful for curing epoxy resins are obtained.

Abstract: 1312763 Dial gauge measuring thickness of coating H TINSLEY & CO Ltd 3 March 1972 [8 March 1971] 6317/71 Heading G1M A gauge for measuring the thickness of a non- magnetic film on a ferrous body 25 comprises, a sleeve 2 slidably positioned for datum purposes at locations 3a 3b of a dial gauge casing, and a tube 6 of aluminium or its alloy slidable in the sleeve 2 and carrying a magnet 7 at one end and at its other end having a plug 8 provided with a brass pin 9 sliding in a slot 10 in the sleeve. The tube 6 has a tension spring 11 fixed to the plug 8 and at its other end the spring is tension adjusted by being fixed to a screw in the end of the sleeve 2. An indicating needle 12 counter-balanced at 14 and pivoted at 13 may be moved from the Fig.1 datum position by sliding movement of the abutting pin 9, which movement takes place when the magnet 7 is attracted to the end of the sleeve 2 by placing the gauge with its end 5 against the ferrous body 25. If the gauge is now drawn away from the body 25 the magnet 7 will be held by the attraction and withdrawn slightly from the end 5, and this movement will slide the pin 9 and move the pointer 12 over the gauge markings. Further movement of the apparatus finally breaks the magnet away from the ferrous body 25 and the magnet then retracts into the tube 6 and the pin 9 leaves the balanced pointer behind which remains in position indicating a reading on the gauge, the final pointer position depending on and indicating the thickness of the non- magnetic film on the body 25. A pointer reset mechanism 19, 20 operated by a plunger 23 is also provided.
