The internal and external teeth 30, 32 of the gear ring 25 are respectively formed by grooves 31, 33, of annular cavity 12a defined by stationary mould parts 11 and 12, 12b. An annular thermoplastics preform, preheated in a furnace to a temperature just below its crystalline melting point, is located in the cavity 12a, and a hydraulic ram 17 descends to sealingly engage a plunger 13, comprising outer annular and inner parts, against the upper surfaces of mould parts 11, 12, 12b, to close the ends of the grooves 31, 33. The plunger 13 is mounted to the ram 17 for lost motion, against springs 18, permitting continued movement of the ram 17 so that an annular plunger 14, carried thereby for sliding movement within an annular groove 19 of ram 13, enters the cavity 12a to displace the preheated blank radially outwardly, and into the grooves 31, 33. Upon raising the ram 17, the gear wheel 25 is ejected by pins 34 displaced by a member 37. The plunger 14 is mounted to the ram 17 by four slides 15 passing through the plunger 13. The die parts may have conduits for passage of oil or water, cooling or heating medium. The gear wheel of the parent Application having external teeth and a central bore, may be moulded in a die heated to specified temperatures, from polymers pre-heated to specified temperatures and comprising a homo- or co-polymer of propylene, nylon 6, and ultrahigh molecular weight polyethylene. The forging pressure is maintained for a dwell time, during which the pressure is reduced for the polyethylene.

Abstract: 935,975. Television. STANDARD TELEPHONES & CABLES Ltd. Dec. 24, 1959 [Dec. 30, 1958], No. 43886/59. Class 40 (3). In a direct current reinsertion circuit for a television system a D.C. signal dependent on the back porch signal level of the video signal is derived across the cathode circuit 54, 55 of a triode 22 which receives the video signal 30 on its anode and is pulsed into conduction during the back porch intervals 29 by keying pulses 50 which are applied to the grid, the keying pulses being derived from an amplifier 44 to which synchronizing pulses 28 separated at 25 and differentiated at 39, 40 are applied via a rectifier 42 which forms part of a circuit 40, 42, 49 to bias the amplifier to saturation whereby an output 50 is produced only in response to the negative differentiation components which occur in the back porch intervals. The D.C. signal from the cathode circuit 54, 55 is resistively coupled to an electrode (the grid, as shown) of the cathode-ray tube 16 in the case of a receiver or an amplifier in the case of a transmitter. The synchronizing pulses 28 are separated by a noise-immune separator circuit which receives video inputs of both positive and negative polarity. Picture mean brightness is adjusted by potentiometer 58 which controls the anode voltage of triode 22. Switches 51 and 52, together with a grounded grid amplifier 61 which is fed from a cathode circuit 7 of the video amplifier 5, are included to permit operation with original television signals corresponding to either positive or negative modulation. Specification 836,217 is referred to.

Abstract: 1,141,419. Crystallization of urea. STAMICARBON N.V. 27 Sept., 1967 [30 Sept., 1966]. No. 44034/67. Heading C2C. A process for the continuous crystallization of urea from a biuret-contaminated solution of urea in water comprises subjecting the urea solution to a first vacuum crystallization at 40-70‹ C. to crystallize and remove from 90 to 95% of the supplied urea in the form of crystals, and subjecting the mother liquor to a second vacuum crystallization at 90-110‹ C. to crystallize and remove further urea crystals, and discharging the final mother liquor containing from 21 to 28% by weight of biuret. The final mother liquor obtained may be recycled to a urea synthesis zone or the final mother liquor may be treated whereby the biuret content therein is lowered, and the thus obtained mother liquor depleted in biuret may be recycled to the first urea crystallization stage. The biuret content of the final mother liquor may be depleted by heating it at 130- 160‹ C. under an ammonia pressure of 1 to 5 atmospheres, or by diluting and cooling it and isolating the biuret crystals thus formed.

Title: High voltage circuit breaker

Filed: 1975-10-27
Abstract: 1522504 Multi-gap circuit breaker LICENTIA PATENT VERWALTUNGS GmbH 27 Oct 1975 [26 Oct 1974] 44186/75 Heading H1N A circuit breaker comprises a plurality of breaker gaps each shunted by a capacitor to provide voltage distribution and at least one being additionally shunted by a resistor in series with a normally-open switch, the operation of the switch being controlled by a device which monitors current through the breaker and closes the switch only when the current exceeds a predetermined value. Thus at lower values of current the circuit is opened by all of the breaker gaps in series, but at high values of short-circuit current one or more gaps are shunted by resistances of about 10 ohms by closure of the series switch thus reducing the amplitude of the current to be broken by the remaining gaps and damping the recovery voltage. The control device comprises a core 2 surrounding the line 1 so that an armature 3 will be attracted when the current exceeds a set value determined by adjustment of a spring 9. Thus a valve 4 is opened to actuate a piston 7 to close switch Tr against a return spring 10.

Abstract: 1277026 Making grommets; forging ARMSTRONG PATENTS CO Ltd 25 Sept 1969 [25 Sept 1968] 45467/68 Headings B3A and B3H [Also in Division F2] An olive 10 comprises a tubular sleeve having tapering, outwardly directed, frusto-conical surfaces 12, 14 for coacting with frusto-conical surfaces 50, 56 of a body member 36 and nut 40 respectively. Adjacent each end of the olive and inwardly spaced therefrom is a single radially inwardly projecting land 32, a pipe 48 being slidingly engageable in these lands when the olive is undeformed. Upon tightening the clamping nut (a) the land at the end of the olive coacting with the long taper 50 of the body bites into the pipe and the end 34 of the olive is bent over to contact the pipe wall (b) the land at the end of the olive coacting with the steep taper 56 of the nut is pressed into contact with the pipe wall (but does not appreciably bite into it), and the end 34 is again pressed into contact with the tube wall. As a result of the action of the steep taper 56 of the nut it is easy to determine when the joint is tight as the nut because suddenly more difficult to turn when the end 34 contacts the pipe wall. Preferably the angle between the external surface 14 of the olive and the taper 50 of the body is between 5 and 15 degrees, while the corresponding angle between tapers 12 and 56 approximates to 45 degrees and exceeds 15 degrees. The olive is preferably centro symmetric and may be machined from tubular stock, but according to one aspect of the invention is made by die stamping (after the machining or otherwise forming the external tapers 12, 14). Two die halves (18, 20) (Fig. 2, not shown) are formed with through holes (22, 24) and are adapted to meet in a radial plane of the olive such that the through holes and the bore of the olive are coaxial, the olive being held in conical recesses in the die halves complementary to tapers 12, 14. A punch is driven in to the bore of the olive via each through hole and displaces material to form the land. There may be two punches applied simultaneously from each end or one punch applied successively to each end. The lands formed by punching have radially planar outwardly facing surfaces and rounded inwardly facing surfaces (Fig. 3, not shown). If the olive is made by machining each land may have a radially planar outwardly facing surface, a right cylindrical axially extending surface and a frusto-conical inwardly facing surface.
