Title: Improvements in starters for internal-combustion engines
IPC: F02N99/00
Filed: 1942-07-21
Abstract: 564,995. Epicyclic gearing. JACK & HEINTZ, INC. July 21, 1942, No. 10179. Convention date, July 21, 1941. [Class 80 (i)] [Also in Groups XXVII and XXXIV] In an engine starter comprising an inertia wheel 6 connected through toothed and planetary gearing to a clutch member 56 engageable with the engine to be started, interleaved friction plates 44, 45 for normally restraining an internally toothed element of the gearing to effect the transmission of torque to the engine, and spring means 49 controlling the amount of this restraint; cam means are provided which are responsive to torque to reduce the restraining force when the torque exceeds a predetermined value. As shown, the inertia wheel 6 is mounted on the shaft 4 of an electric motor 2 enclosed in a section 5, of the starter housing. The transmission gearing includes a pinion 10 on the shaft 4 .meshing with a gear 13 on a countershaft 14 carrying a pinion 19 in mesh with an internal gear 20 mounted on a shaft 23. The shaft 23 can be driven manually, for setting the inertia wheel 6 in rotation, through bevel and spur gearing 26, 27, 29, 32, 33 from a socket 34 actuated by a cranking handle. A sun gear 38 on the shaft 23 meshes with one or more planet gears 39 carried by a spider 43 and meshing with internal teeth on friction plates 44 interleaved with friction plates 45 splined to a reaction ring 47 capable of slight rotation in the section 21 of the housing. A sleeve extension 43c of the spider 43 is in splined connection at 57 with the clutch member 56. The reaction ring 47 is formed with cam members co-operating with cam members on a pressure ring 48 splined in the housing section 41, springs 49 being interposed between the ring 48 and plate 50 adjusted by means of screws 54. The inclined engaging faces of the cam members are formed to include a series of involute curves evolved from a base circle having a diameter preferably more than .7 and not greater than .9 of the mean diameter of the reaction rings, the starting points of the involutes forming a helix on the base circle. In operation, the friction plates 44, 45 tend to cause the reaction ring 47 to rotate and the cam members to effect axial movement of the pressure plate 48 against the springs, relieving momentarily the friction between the plates 44, 45 when the driving torque is excessive. Specification 550,689 is referred to.

Abstract: 833,532. Controlling nuclear reactors. BRITISH THOMSON-HOUSTON CO. Ltd. March 28, 1958 [March 28, 1957], No. 10197/57. Class 39(4). [Also in Group XXXVII] Equipment for raising and lowering the control rods of a nuclear reactor comprises an electric motor 17 having a permanent magnet rotor 1 and twophase stator windings 2, 3. The motor drives a winding drum 18 which is geared to a double cam 21 for operating switches 11, 12, and 13, 14. Under emergency conditions, the supply to the motor is disconnected and the load is allowed to fall. Initially only permanent braking resistors 5, 6, are connected in circuit and the motor is driven at high speed until switches 11, 12, are closed after a predetermined number of revolutions of the motor. Resistors 7, 8, are thus included in circuit to increase the braking effect. The speed is reduced further by the inclusion of resistors 9, 10 so that the bottom limit of travel is approached at a low speed. The load may be brought finally to rest by mechanical braking.

Abstract: 1459982 Permanent and electromagnets; magnetizing VEEDER INDUSTRIES Inc 12 March 1975 [13 March 1974] 10293/75 Heading H1P [Also in Division G1] An asymmetrical magnet for a rotary pulse generator incorporating a Hall sensor generating a train of electrical signals comprises a spool shaped rotor 10 (Fig. 2) wherein a pair of circular disc permanent magnets 16 are supported on a hub 18 for rotation with a shaft 18 with an axial gap 20 between the discs; co-operating with an assembly 12 positioned within the gap comprising a Hall sensor 24 in a D.C. power supply, to act as a solid state pulsing switch on application of unidirectional magnetic flux. A sensor and amplifier may be incorporated in a single Si integrated circuit. The magnets 16 are of, e.g. barium ferrite ceramic, magnetizable to present plural assymmetric pole pairs 30 having predominant poles 32 and subordinate poles 34 symmetrically and radially orientated round the circumference. The predominant poles occupy twice the areas of the subordinate poles, and the discs are angularly orientated so that predominant and subordinate poles of the respective discs are in confrontation to produce a ring of flux columns in alternating directions in which the predominant poles overcome the subordinate poles. Angular displacement of assembly 10 relative to sensor 12 sinusoidally varies the flux therein without polarity reversal (Figs. 3, 4, not shown). The magnet discs are permanently magnetized by application to a head 28 (Fig. 6) having a cylindrical tubular ferromagnetic core member 40 with plural, e.g. 20 equally spaced axially extending segments 42 at one end defining, e.g. 10 pole pairs 30; alternate segments having a conductive winding 44 over insulant, e.g. epoxy layers 50 enclosed in a protective, e.g. epoxy casing 52; the windings being energized in series over leads 54.

Abstract: 864,141. Indicating liquid levels. CULK, R. March 26, 1959 [April 4, 1958], No. 10581/59. Class 123(1) Means for indicating the level of liquid in the collecting container 1 of a refrigerator comprises at least two shut-off valves 5 the outlets 10 of which are located at the upper and lower limits of liquid level. One or more shut-off valves can be incorporated at intermediate levels and if the container is of irregular cross-sectional shape the intermediate valves are arranged on levels which divide the column of liquid into equal volumes. Each shutoff valve comprises a nipple 5 which is brazed into the wall of the container and has a bore which forms a seat for the coned end of a valve stem 7 which threadedly engages in an enlarged portion of the bore, has transverse and axial bores 9,10, and an externally projecting square end to facilitate axial adjustment. The nipple 5 is externally threaded to receive a cover cap 11. To check the liquid level in the container 1 the valves are opened for a short time, successively from top to bottom, the escape of liquid refrigerant being recognised in the form of a white vapour which subsequently freezes on the valve. Gaseous refrigerant escaping remains invisible and does not freeze on the associated valve. In a modification the valves, brazed into a horizontally disposed container, carry protruding hexagonal heads for axial adjustment, the caps 11 being omitted. A horizonta ly disposed container is also shown having the valves spaced across the top of the container the nipples being extended by small pipes which form outlet openings for the refrigerant at various levels. In a further modification, the valves, disposed in a horizontal centre plane of the container, are extended to various levels by pipes curving upwardly and downwardly. The nipples could also be vertically spaced in the wall of a horizontally disposed container.
