Title: Improvements in rotary air pumps or compressors
IPC: F04C29/00
Filed: 1931-12-16
Abstract: 393,977. Lubricating rotary compressors. NICHOLS, T. W., 63, Capel Road, Forest Gate, London. Dec. 16, 1931, No. 34884. Addition to 331,054, [Class 110 (ii), Rotary engines &c.]. [Class 12 (iii).] In a compressor having an eccentric rotor A having teeth meshing with a revoluble ring B in a casing C, and outwardly sliding vanes D, the oil provided for lubricating the compressor is sprayed into the incoming air entering at E by way of a nozzle S under pressure of the delivery air. The air is delivered by the rotor through two ports G into baffle chambers H and through narrow orifices N where the oil is separated out into traps O leading to the oil sump P, and the air passes on through a passage Q to the outlet F. The pressure of the delivery air acts on and forces down a piston valve U, Fig. 4, so that oil from the sump P is forced up a pipe P<1> to a regulator L, which may be a needle valve, and through a sight glass M to the nozzle S. When the compressor stops, the valve U rises under the action of a spring V and shuts off the oil sump from the pipe P<1>. Cooling water enters a port T and circulates above and below the baffle chamber through compartments R, and leaves at an outlet T<1>. When the machine is to be used as an exhauster, air cooling only may be provided, and a non- return valve X may be fitted at the delivery F, and the valve U dispensed with. Strainers for the oil are provided. Extra oil pipes P<1> may be fitted. Each tooth on the rotor A may be split up into a number of teeth, and each slot in the ring correspondingly split up. The apparatus may be fitted to other types of rotary pumps or compressors.

Abstract: 480,667. Valve generating circuits ; electron multipliers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 28, 1936, No. 34920/37. Convention date, Oct. 28, 1935. Divided out of 484,160. [Classes 39 (i) and 40 (v)] In an electron-multiply. ing oscillator having twc cold cathodes (dynodes) C C<1>, arranged on either side of an anode A so con structed that electrons can pass through it, e.g. ring shaped, and with an electromagnetic or electrostatic field for directing the electron paths through the anode, the frequency of oscillation is stabilized by connecting the dynodes to a sharply-resonant line structure or a sharply-resonant electro-mechanical vibratory device. The line structure TL, Fig. 2, of length corresponding to a half-wave length, is mounted at its centre D inside a grounded hollow conductor S serving as a shield. Oscillations corresponding to even harmonics may be taken off from a tuned circuit R<1> in the anode circuit. Another arrangement, Fig. 3 (not shown), employs a piezo-electric crystal shunted by an impedance having its mid-point connected to the anode battery B. A third arrangement, Fig. 4, employs a vibrator MC acting by magneto-striction, the fundamental frequency and odd harmonics being taken off at O<1> and even harmonics as before at O. Since such a vibrator is usually of relatively lower frequency, additional anodes A<1> maintained at a negative potential are provided to increase the time of flight of the electrons. Fig. 5 shows a tube having an electrostatic field produced by applying a potential to guard-rings GR surrounding the dynodes, the anode consisting of a perforated plate P having a solid surface, small compared with the area of the perforations, e.g. an open-mesh network of very fine wire. The oscillators may be used also as detectors, e.g. by applying signals to the guardrings GR, Fig. 5, and adjusting the anode battery to give maximum current, or as amplifiers by adjusting the anode battery to a point where increased voltage causes increased current giving an ordinary amplifier effect or to a point where increased voltage causes decreased current giving a negative-resistance effect.

Abstract: 841,860. Nuclear fuel processing. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 12, 1958 [Nov. 12, 1957], No. 35161/57. Class 39(4). A fissile or fertile oxide is recovered from a dispersion in a metal consisting wholly or predominantly of iron by melting the metal in an inert atmosphere so that the oxide collects on the surface of the molten metal, and separating the oxide mechanically. The metal may be melted in a vessel provided with a spout connected to the bottom of the vessel, so that pure molten metal may be continuously withdrawn, the oxide being removed by vacuum suction. Alternatively the metal may be solidified before separation of the oxide. Oxide of uranium, plutonium, and thorium may be separated from pure iron, cast iron, or mild steel by melting in a graphite vessel in an atmosphere of argon. The Provisional Specification refers to the removal of carbides, silicates, and beryllides of uranium and plutonium, and the range of metals is extended to include aluminium, zirconium and beryllium.

Title: Protective mechanism for doors
IPC: B66B13/26
Filed: 1954-12-07
Abstract: 759,240. Door-operating apparatus. OTIS ELEVATOR CO. Dec. 7, 1954 (Dec. 21, 1953], No. 35386/54. Class 65 (1). In operating mechanism for a door 10 with a protective edge 25 adapted to yield on contact with an obstacle and thus to actuate a switch which stops or reverses the mechanism, means are provided to retract the edge when the door is fully open, to increase the opening, without affecting the protective action. In the arrangement shown in the open position, the edge 25 is supported on the door by two levers 26, 27, the latter having a balancing spring attached to it. The upper lever 26 is pivoted at 32 and has an extension in engagement with the actuating member of a switch 40 carried on a plate 35 which is also mounted on the pivot 32 and which is connected to a link 17 of the dooroperating mechanism by links 60, 62 and a lever 61 on the door. As the door is closed, the link 17 at first swings downwards, raising the link 60 and allowing the edge 25 to swing outwards, while maintaining the switch 40 in the ineffective position ; near the closed position the link 17 swings upwards, forcing down the link 60 and retracting the edge. In both these movements the members 35, 26 move together, but if the edge 25 is pushed in, in any position of the door, the member 26 moves relatively to 35 to allow the switch 40 to move to the position in which closing of the door is stopped or prevented. In a modification, Fig. 1 (not shown), the link 60 is connected to a lever which has a roller for engagement with cams arranged to lift the lever at each end of the door movement, to depress the link 60 and retract the edge; a spring urges the link upwards against an adjustable stop. In other arrangements, the switch may be engaged, instead of released, by actuation of the edge; it may be mounted on the lever 26; and the retraction of the edge in the closed position may be omitted. In a further modification, the edge 25 may be formed with a separate edge portion which operates the switch when it is moved relatively to the main portion, and the switch is thus unaffected when the two portions are retracted together.

Title: Improved circuit arrangement for capacitor motors
IPC: H02P1/44
Filed: 1955-12-09
Abstract: 774,369. Control of A.C. motors. GENERAL ELECTRIC CO. Dec. 9, 1955. [Dec. 9, 1954], No. 35442/55. Class 38(3) Relates to a control system involving the use of two capacitor motors 1, 2, wherein a common capacitor 32 is provided for series connection with the auxiliary windings 4, 6, of the two motors. To operate both motors, switch 9 is closed as well as the ganged switches 34, 37 and 27, the main winding 3 of the motor 1 being connected directly across the single-phase supply-lines and the auxiliary winding 4 in series with the parallel-combination of the capacitors 32 and 26. As the motor reaches full speed, the voltage across winding 4 and relay coil 24 increases sufficiently to open contact 22 and disconnect the capacitor 26. A relay 12, which opens when the motor 1 is started, closes contact 13 when the current decreases as the motor reaches normal running conditions, so that windings 5, 6, are energized to start the motor 2. The auxiliary winding 6 is then connected in series with the capacitor 32. To operate the motor 2 alone, the switch 9 only is closed provided that the starting current of the motor is not sufficient to operate the relay 12. If, however, the motor current is large enough to cause the relay to open, the closure of switch 45 will ensure proper connection of the motor. In another arrangement, the parallel-combination of capacitors 51 and 67 and are connected in series with the auxiliary winding 4 for starting the motor 1, whilst capacitor 63 is connected in series with auxiliary winding 6 for starting the motor 2. When the motor 1 approaches full-speed, the capacitor 67 is disconnected and capacitors 51 63, are connected in parallel. In a further modification, the motor 1. is operated at full speed with a parallel-combination of two capacitors (or a single split capacitor) connected in series with its auxiliary winding, whereas, when the motor 2 is operated alone, it utilizes only part of this capacitance, Fig. 3 (not shown). The motor 2 may have two auxiliary windings which are connected in series with each other for starting when the first motor is operative, and in parallel when the motor 2 is running alone, Fig. 4 (not shown). The two motors may drive respectively a compressor 'and a fan of an air-conditioning pliant.
