Patent GB-605454-A (GB)
Title: Improvements in or relating to radio-location systems
IPC: G01S13/53
Filed: 1945-02-28
Abstract: 605,454. Radiolocation. GRAYSON, H., and BROWN, D. E. Feb. 28, 1946, No. 5065. Drawings to Specification. (Class 40 (vii)] In a radar system, wherein the Doppler effect is employed to differentiate between fixed and moving targets, reflected echoes of the exploring pulses of radio frequency are mixed with a locally-generated reference oscillation having a predetermined phase relationship with the oscillation of the transmitted pulse. Either the radio frequency or the reference oscillation is derived, one from the other, by the mixing of one with the output of a stable oscillator. The reference oscillation may either comprise a continuous oscillation or an intermittent oscillation persisting after the transmitted pulse sufficiently long to encompass the received echo pulses. In one embodiment of the invention the reference oscillation is generated from an oscillator, the output of which is periodically amplified to produce the exploring pulses, by mixing the output of saidoscillator with the output from the local oscillator of the superheterodyne receiver of the radar system. The reference oscillation which is thus at the intermediate frequency is mixed with the received signals either in the intermediate frequency amplifier or in the second detector. In a second embodiment the output from an oscillator generating signals at the intermediate frequency is mixed with the output of the local oscillator, the resultant signal, which serves as the reference oscillation, being injected into the pulse transmitter to synchronise the oscillation of each transmitted pulse. The reference signal is also injected into the radio frequency stages or the frequency changer of the receiver. In a third embodiment wherein an intermediate frequency oscillator operates as before to control the oscillations of the transmitted pulses, the output of the oscillator serves as the reference oscillation and is injected into the intermediate frequency amplifier or second detector. When echoes from moving targets are being received, the output from the second detector contains a component at the Doppler beat frequency, which is filtered off, amplified and applied to an indicating device such as a loud speaker, cathode-ray tube or tuned reed indicator. Provision may be made for varying the pulserecurrence frequency since the amplitude of the Doppler beat signal of the any particular frequency depends upon its relationship with the pulse recurrence frequency and might in certain circumstances become zero. Strobing may be provided to select one of a number of echo pulses. Specifications 596,650 and 596,657 are referred to.

Title: Improvements in or relating to refrigerating apparatus
IPC: F25B49/02
Filed: 1937-02-22
Abstract: 480,142. Refrigerating. WESTING- HOUSE ELECTRIC & MANUFACTURING CO. Feb. 22, 1937, No. 5184. Convention date, March 3, 1936. [Class 29] Compression machines and systems.-A refrigerating system having high and low temperature evaporators is provided with a refrigerant liquid flow control device normally disposed in one position in which refrigerant is supplied to, and vaporized in, the high temperature evaporator, and movable by hand to a second position in which the refrigerant is supplied to, and vaporized in, the low temperature evaporator. Means responsive to a predetermined low temperature in the low temperature evaporator is provided to return the control device to its normal position. A system for a refrigerator cabinet includes an enclosed motor-compressor unit 28, condenser 29, and a low temperature evaporator consisting of interconnected hollow shelves for supporting ice trays and connected in series with a high temperature evaporator consisting of interconnected hollow walls 14, 15 which, together with bottom and end plates 43, enclose the shelves. The control device comprises a vessel 36 having an electromagnetically-operated plunger 37 and interposed between the condenser and the floatvalve chamber 34 controlling the flow of refrigerant to the evaporators. The control device is regulated by mechanism comprising a bracket 61 to which is pivoted a lever carrying contacts 53, 54 and urged to the left by a spring 48 and to the right by bellows 49 connected to a thermostat bulb in contact with the lowest shelf of the low temperature evaporator. The bracket also supports a spring arm carrying flexible contact strips 57, 58 and an adjustable armature 63 which coacts with an electromagnet 64. In the normal position shown, in which refrigerant overflows from the low to the high temperature evaporator, the current supply to the compressor motor is controlled by a thermostat 42 in the cabinet. When the temperature of the air in the cabinet reaches a predetermined value, the thermostat closes the circuit through a starting relay 66 and sets the motor in operation. When it is desired to operate the low temperature evaporator the armature 63 is pressed into contact . with the magnet 64 so that the contacts on the strips 57, 58 abut against the contacts 53, 54 thus completing circuits through the solenoid 39 operating the plunger 37, which is moved to its upper position thus trapping refrigerant in the vessel 36, and the starting relay 66. The control of the current supply through the relay is thus independent of the thermostat 42. When the temperature in the low temperature evaporator reaches a predetermined minimum value, the bellows 49 contracts and the circuits are broken so that the plunger 37 returns to its normal or lower position. The armature 63 may be adjusted to such a position to the right that after it has been pressed into contact with the magnet 64, the thermostat is unable to effect rupture of the circuits. Specification 446,599 is referred to.

Repelling magnets 60-63 are provided between the main magnets. A mixture 35 of magnetic and non-magnetic material is directed in close proximity to the faces of the magnets and through magnetic fields produced by the main magnets to separate the material. As described, a non-magnetic cylindrical shell 11 rotates on bearings about a shaft 12, driven by a motor, chain and sprocket 18, 17, 15. The fixed permanent magnet 20 is mounted concentrically with and inside the shell 11. In operation, the shell conveys material through the alternating magnetic field, so that the magnetizable material is rotated and remains attached to the shell until it comes to a portion past the pole 29, when the magnet 20 is no longer effective and the magnetic material falls off. Water is supplied via a conduit 37 to a chamber 36, the separated material is delivered by a chute 55, non- magnetic tailings via a pipe 54 and water via a pipe 48. Instead of separate water and material feeds there may be a direct feed of slurry. A further embodiment employs bucking magnets 206 . . . 209, Fig. 4, fixed to an adjustable magnetic back bar 300, which permits shaping and variation of the magnetic field in accordance with the characteristics of the material to be separated.
