Title: Apparatus and method for the production of castings from metal-gas alloys
IPC: B22D17/00

Abstract: 1,269,145. Die-casting. INSTITUT PO METALOZNANIE I TECHNOLOGIA NA METALITE. 3 Oct., 1969 [10 Oct., 1968], No. 48795/69. Heading B3F. [Also in Division C7] To produce a casting containing dissolved or chemically bound gas, molten metal 1 is saturated with gas from a reservoir 6 through a pipe 8 and fed under pressure into a closed mould 11 which contains the same gas under pressure so that the mould gas is raised to a pressure above the saturating pressure to prevent gas separating out of the metal. The shot of melt is raised into a cylinder 14 by feeding more gas into the melt 1 to increase the gas pressure in a chamber 3 (containing the melt receptacle surrounded by a heater and is forced by a piston 15 into the mould 11 against the pressure created by gas supplied through a cock 9 to a chamber 10 containing the mould 11. The gas in the mould is forced into a top member 12 and this is opened after solidification and after the gas from the chamber 10 has been passed through a circulation-regeneration system 16 whence it may be returned to the reservoir 6. The action of the member 12 may be replaced by a compression cylinder 19 by which the mould gas pressure may be controlled, e.g. increased.

Abstract: 1284266 Printing apparatus NATIONAL RESEARCH DEVELOPMENT CORP 19 Nov 1969 [16 Oct 1968] 49020/68 Heading H4F [Also in Division H1] Relates to printing where material is transferred from a carrier to an adjacent surface or vice versa in response to a scanned modulated beam of radiation, e.g. a laser beam. The surface to be printed may comprise a litho or duplicating master or may comprise a textile, ceramic, metal or paper sheet of other article. The transferred material may comprise ink, dye, etching reactant or gelatine from capsules. In Fig. 1 a textile material 10 and a laminate 16 are fed over bed 13 and a printing compound from the laminate is transferred to material 10 in response to the line scanned pulse-width modulated laser-beam. In a second embodiment, Fig. 2, not shown, gelatine filled capsules are broken by the laser beam so that water-repellent areas are formed on a plate i.e. a litho printing plate, the laser being moved in one direction while the beam thereof is scanned at right angles. The article to be printed may be pre-coated, e.g. with water-repellent material, and this coating may be selectively transferred to the laminate by scanning the laser beam across the article. The laser may comprise a carbon dioxide or neodymium laser modulated by an electrooptic shutter or Q-switched by a Pockel's or dye cell or a movable end mirror. Scanning is effected by servo-controlled mirrors the beam being kept in focus on the laminate by means of a Zoom lens or movable mirrors.

Title: Series motor control
IPC: H02P7/292
Filed: 1962-12-31
Abstract: 960,992. Automatic speed control. TEXAS INSTRUMENTS Inc. Dec. 31, 1962 [Sept. 10, 1962], No. 49029/62. Heading G3R. [Also in Divisions H2 and H3] A series motor 14, 15, is connected to a source of full-wave rectified current through controlled rectifier 16 supplied with gating pulses by discharge of capacitor 21 through the emitter and a base of a unijunction transistor 20. The triggering voltage of the transistor 20 is dependent upon the bias between the first and second bases thereof, this bias being established by the voltage across Zener diode 17. The rate of charge of the capacitor is determined by resistors 22, 23, and the back-E.M.F. of the motor. If the resistor 22 is set at a low value and the motor speed is low, firing will occur early in the half cycle, whilst high resistance in the charging path or high speed will retard firing. A diode 24 shunts series field winding 14 to maintain a back-E.M.F. across the armature.

Title: Direct current control circuit
IPC: H02P3/08
Filed: 1970-10-15
Abstract: 1324338 Control of D.C. motors GENERAL ELECTRIC CO 15 Oct 1970 [21 Sept 1970 (2)] 49055/70 Heading H2J [Also in Division H3] In a system for controlling power from a D.C. source to a load, e.g. a series motor 14, 16, by a solid state switch 20, the primary 18 of a transformer is connected in series with the load, a commutating capacitor 34 and a second solid state switch 32 are connected across the first switch, and a third solid state switch 40 and a secondary winding 38 of the transformer are connected across the capacitor. The controlled rectifiers are thyristors; 20 is triggered first to energize the load, closely followed by 40. The capacitor 34 is permanently connected to the supply via a resistor 36 and the voltage on this passes a current through 38 and 40 which saturates the transformer in the negative direction, whereupon the current rises sharply and, by resonance, reverses the charge on 34. The load current will be increasing to tend to saturate the transformer in the other direction and the resulting voltage across secondary 38 increases the reverse charge on 34. At positive saturation the voltage across 38 collapses, 34 tends to discharge through thyristor 40, turning it off, and the momentary reverse current through 38 is detected by a triggering pulse circuit 42 which then triggers the commutating thyristor 32, so allowing 34 to turn off 20. The load current is diverted through 32 to resonantly charge capacitor 34 to a forward voltage higher than that of the supply, thus back biasing 32 and turning it off. A choke 30 limits the rate of rise of current through 32. The cycle is now repeated after a delay determined by a speed control potentiometer in the pulse generator circuit 42, which, if the load is a traction motor, is coupled to a pedal. The motor field 16 is connected via reversing contactors F1, F2, R1, R2 and there are separate flywheel diodes 54, 56 for the armature and field. A full speed contact 28 shorts 18, 20 but 34 remains charged via 36 and so is ready for use when control via 20 is resumed. The motor is braked by reversing the direction of the field, and controlling the average armature current to a substantially constant value by regulating the triggering of thyristor 20 in response to the voltage across the armature, by a braking circuit 52. The pulse generator 42 and braking circuit 52 are described (Fig. 2, not shown). The former comprises a unijunction transistor relaxation oscillator whose output triggers 20 directly and 40 via a delay circuit, while triggering of 32 occurs when a transistor (100) is made conductive by the reversal of voltage across 38. The braking circuit is a transistor voltage comparator which suspends the relaxation oscillator when the armature voltage exceeds a reference set by a variable resistor.

A rotary-piston I.C. engine of trochoidal type includes an axial seal comprising an oilscraper ring 7, Fig. 1, disposed in an annular groove 5 in the end wall 2 of the piston 3 and secured to one limb 9 of a metal bellows 11 whose other limb 10 is secured in the groove 5 non-rotatively with respect to the piston and a preliminary scraper ring 8 bearing against the inner peripheral surface of the ring 7. The rings are pressed independently of each other into sealing contact with the housing side wall 4, the ring 7 by the bellows and spring means 14 and the ring 8 by spring means 18. Oil which passes the ring 8 is collected in chambers formed by bores 16 between the sealing faces 20, 15 of the rings 8, 7 respectively and discharged by inwardly directed acceleration faces through ports 21 in the housing side wall 4. In a modification, the sealing face 15 may be replaced by an insert of ceramic material or by graphite or sintered materials. The bellows 11 may be shaped to act as a spring in which case the spring means 14 are dispensed with. The chambers in which the oil is collected may instead of being formed in the ring 7 may be formed in the ring 8 and comprise annular chambers disposed radially one outside the other and subdivided into separate chambers by radial ribs. The ring 8 is then provided with driving lugs engageable with complementary grooves in the piston so that the ring 8 rotates with the piston and the oil may again be collected by means of ports in the housing side wall.
