Title: Making continuous filaments of carbon
Inventor: HIGGINS FRANCIS JAMES
IPC: D01F9/28
Filed: 1967-02-22
Abstract: 1,215,005. Carbon fibres. COURTAULDS Ltd. 22 April, 1968 [22 Feb., 1967], No. 8434/67. Heading ClA. Continuous carbon filaments are made by (a) passing a tow of man-made organic filaments through a first zone at 200-300‹ C. in an atmosphere of nitrogen, air, or air enriched with oxygen, the residence time being less than 12 hours; (b) passing the tow through a second zone containing an inert atmosphere, most of which zone is at above 1000‹ C., at such a rate that the maximum temperature is maintained for between 30 mins. and 4 hrs. The filaments may be further heated in an inert atmosphere at below 300‹ C/hr. between 1000‹ C. and 1700‹ C., and the temperature then maintained between 1500‹ C. and 1700‹ C. for not more than 3 hours. Graphitization may be effected by further heating to at least 2000‹ C., preferably at 1000‹ C/hour when above 1700‹ C., and maintaining it at the maximum temperature for from 30 mins. to 3 hrs. The length of the tow is preferably maintained constant in the first heating zone, and controlled in the second so that the ratio of entering: leaving lengths is from 1: 0-8 to 1: 1-2. In the third and fourth heatings, the length ratio may be controlled to from 1:0-9 to 1:1-1. The atmospheres are preferably changed frequently to carry away degradation products. The inert atmosphere may be argon, nitrogen or hydrogen.

Title: Fuel injector for an internal combustion engine
IPC: F02B3/06
Filed: 1976-03-03
Abstract: 1534350 IC engine fuel injectors; fuel injection pumps AMBAC INDUSTRIES Inc 3 March 1976 [4 March 1975] 08452/76 Headings F1A and F1B To terminate injection fuel at injection pressure is directed to the spring chamber 134 to act on the valve 112 and assist closure of the valve by the spring 132 against the fuel at injection pressure in the actuating chamber 122. Prior to a further injection the pressure in the chamber 134 is reduced. Fuel at high pressure from an accumulator is supplied to an inlet 34 and acts on the remote ends of abutting valve pistons 32a, 32b, the end of the piston 32b having the larger cross-sectional area. The chamber at the remote end of the piston 32b is also connected to a drain passage 50 controlled by a valve 52 operated by a solenoid actuator 54 which opens the valve in response to signals generated in response to the speed of an associated engine. Displacement of the pistons 32a, 32b from the postion shown in Fig. 1 to that shown in Fig. 3 connects the inlet 34 to the cylinder 72 of the piston 66 which operates the injection piston 64 to supply fuel to the chamber 122 and open the valve 112. When or immediately before the piston 64 seals its pumping bore 86 from the chamber 122, the bore is connected via passages 146, 148 in the piston to the chamber 134. A metered quantity of fuel from a shuttle metering device is fed via an inlet 76, a passage 78, an annulus 80 of the piston 32b and a passage 84 to the bore 86 when the pistons 32a and 32b are in the position shown in Fig. 1. The pressure of this metered fuel replaces the injection pressure in the chamber 134. The Fig. 1 position of the pistons 32a and 32b connects the cylinder 72 to a drain port 167 to permit the pistons 64 and 66 to be moved against the bias of the spring 74 by the metered fuel.

Title: Improvements relating to windscreen wiper mechanism
IPC: B60S1/08
Filed: 1954-03-24
Abstract: 750,465. Control of motors; switches, partly electromagnetic. GENERAL MOTORS CORPORATION. March 24, 1954 [April 6, 1953], No. 8546/54. Classes 38(3) and 38(5) [Also in Group XXIII] Relates to the control of an electric motor in a windscreen wiper mechanism (see Group XXIII) and an automatically operated switch, the action of which is modified electromagnetically. The motor 10, Fig. 1, drives a motion converting mechanism 11 to oscillate a shaft 12 and thus wiper arms 13, 14 through a predetermined arc, the mechanism 11 being designed so that the wiping arc can be increased automatically to park the wipers outside the normal wiping arc. The wiper arm 14 is connected to an actuator member 45, provided with a head 46 and in slidable engagement with a resilient arm 24 carrying a contact 25 coacting with a fixed contact 27. When the arm 14 is moved to left in Fig. 1 towards its parking position the head 46 engages the arm 24 to separate the contacts 25, 27. The contact 27 is carried by a resilient member 39 and its position is adjustable by a screw 40. An electromagnetic winding 21 arranged in series with the motor circuit causes the magnetization of a core 35 whenever the motor is energized, and thus the attraction of an armature 36 secured to the contact arm 24. Referring to Fig. 2, when a manual switch arm 28 is rotated to bridge contacts 22, 30 and a variable resistor 33, the motor 10 is energized and the contacts 25, 27 when periodically operated have no effect. However when the arm 28 is rotated to bridge the contact 30 and a contact 26 the contacts 25, 27 are included in the motor circuit and the motor continues to rotate until the contacts are opened by the member 45, 46. Opening of the contacts 25, 27 is modified by the current flowing through the winding 21 which is the same as the motor current. If the friction between the wiper blades and the windscreen is light, e.g. when the windscreen is wet, the motor and thus the coil current is small and the contacts 25, 27 open quickly as the wiper arm moves to its parked position and the motor intertia does not then cause overtravel of the blades beyond the parking position. If the friction is high, e.g. when the windscreen is tacky, the motor and coil current is high and the opening of the contacts 25, 27 is retarded but occurs at a time when there is still sufficient motor inertia present to move the blades to the parked position. The member 45 may be controlled from the mechanism 11 in which case it is only operated when the arc of wiping is increased for the purposes of parking.

[Classes 5 (i) and 6 (i)] Apparatus for treating turf and soil by piercing or making holes therein for aeration, killing grubs, &c., comprises a tine-carrying plate or member provided with means for raising it periodically, releasing it quickly, and allowing it to fall freely. A frame 1 mounted on pneumatic or other wheels 6 is provided with four vertical guide bars 7 along which a plate 8 carrying tines 9 is freely movable. The tines 9 may be adjustably mounted in slots. They may be solid, or may be made hollow so as to extract cores of earth. The holes made may be filled with compost. For killing leather jackets shanks carrying plates provided with closely spaced tines may be substituted for the tines 9. Two cross-shafts 10, 11 are driven in unison, but in opposite directions, from an engine 15. Double arms 10c, lie on these shafts_carry antifriction rollers 10d, 11d which engage projections on the plate 8 and so lift it as they are carried round. In the highest position of the plate 8 the arms enter slots in it and thus allow it to fall freely. Springs 7b cushion the plate when it falls and adjustable and interchangeable springs 7c and weights 8c cause it to fall quickly when released. The machine may be moved forward intermittently by the engagement of gear segments 10f on a double arm 10e on the shaft 10 with gear wheels 5a on the front axle 5. The bearings 4a of this axle are movable against the action of springs 4b. A handwheel may be mounted on one of the shafts 10, 11 for the purpose of setting the machine with the plate 8 raised for transport. Handles 1d may be provided for steering and propelling purposes. According to the Provisional Specification the plate may be raised by cams, eccentrics, &c., and the tines may be rotated as they penetrate the ground.

Title: Plasticized polymeric vinyl or vinylidene halide composition and method of making same
IPC: C08L27/04
Filed: 1951-04-16
Abstract: A polymer of a compound of the general formula <FORM:0711853/IV (a)/1> where X is hydrogen, chlorine, fluorine or bromine and Y is chlorine, fluorine or bromine, is plasticized by intimately mixing with a copolymer of a conjugated diolefinic compound of less than seven carbon atoms in a straight chain with a mono-olefinic material having a carbonyl group the carbon of which has only two of its four valency bonds connected to oxygen.  Materials which may be plasticized are polymers and copolymers of vinyl chloride, vinyl fluoride, vinyl bromide and vinylidine chloride.  These may be substituted in part by resins containing polar groups, such as copolymers of acrylonitrile or methacrylonitrile with styrene or substituted styrene and other polymers and copolymers of halogenated and alpha-methyl styrene.  The carbonyl components of the plasticizers include unsaturated ketones and aldehydes, e.g. methyl isopropenyl ketone, methyl vinyl ketone and vinyl phenyl ketone, and acetyl styrene and acetyl alphamethyl styrene having the acetyl group para or meta to the isopropenyl group.  The diolefinic component of the plasticizer may be butadiene, isoprene, chloroprene, cyanoprene or dimethyl butadiene.  The rubber copolymer preferably contains 40-65 per cent. of diolefinic compound and 60-35 per cent. of the carbonyl component which may be substituted in part by another monomer such as acrylonitrile or methacrylonitrile.  The preferred copolymers are almost viscous liquids having a Mooney viscosity of below 30.  The two components are preferably mixed by mixing the copolymer latex with a latex or aqueous slurry of the vinyl polymer, or they may be milled dry. Other plasticizers may be added, as well as stabilizers such as lead stearate and silicate, and antioxidants such as heptylated diphenylamine.  After coagulating, washing and drying, the products may be calendered into films, &c.  The preparation of the diolefinic copolymers with methyl isoproponyl ketone is described, in which an aqueous emulsion of the monomers is maintained at 50 DEG C. in the presence of a soap, potassium persulphate catalyst and a mercaptan.  Specification 644,022 is referred to. Specification 711,843 also is referred to.

Filed: 1946-03-22
Abstract: 618,247. Automatic control systems. GENERAL ELECTRIC CO., Ltd., and DALE, S. H. March 22, 1946, No. 8888. [Classes 38 (ii) and 38 (iv)] Current and voltage.-In a regulating system, the quantity to be regulated controls the output of a rectifier and this output is balanced against the output of a further rectifier, both rectifiers being fed from the same source, variations in which are thus balanced out. Alternatively the rectifiers may be fed from distinct sources which vary in the same way. As shown, the voltage at the output of a gridcontrolled power system controls the value of a saturable choke in series with the input side of a bridge rectifier 2 feeding a resistor 16 and an adjustable choke 41 is connected in the input circuit of a second rectifier 1, the output of which feeds a resistor 15. The resistor 16 and an adjustable part of the resistor 15 are included in series so as to act in opposition in the grid circuit of an amplifier tube controlling a saturable choke 35. When the output voltage of the main rectifier varies a corresponding change occurs in the voltage across resistor 16 and consequently in the value of choke 35 and then causes a phase shift of the input to the power rectifier in such a direction as to correct the voltage variation. The arrangement may be adapted to polyphase systems and the phase-shifting arrangement may be of a rotary type instead of the static type shown. In another arrangement, Fig. 1 (not shown), control is exercised in accordance with the current flowing in a D.C. line.
