Title: System for detecting overheated wheels on railway vehicles
IPC: B61K9/06
Filed: 1960-10-25
Abstract: 906,170. Detecting overheated vehicle wheels. GENERAL RAILWAY SIGNAL CO. Oct. 25, 1960 [Oct. 30, 1959], No. 36591/60. Class 40 (3). [Also in Group XXX] In a system for detecting overheating of the wheels of railway rolling-stock due to friction, two infrared detectors, positioned one on each side of the track, scan each passing wheel and in conjunction with gating circuits controlled by magnetic wheel flange detectors produce signals indicative of the presence of an overheated axle box or a dragging brake, which are recorded. Radiation detectors RD1, RD2 receive radiation from a direction 12 and scan each passing wheel along a line parallel to the track and passing through the wheel hub. Magnetic detectors WD1-WD3, each of which produces an output signal as a wheel flange passes through its magnetic circuit are disposed on the track such that during the period a wheel is between detectors WD1 and WD2 each radiation detector scans its associated wheel hub and when between detectors WD2 and WD3 it scans the wheel web and rim. Two flip-flop circuits are controlled by the magnetic detectors, the first supplies an output to open gates 82, 84 when the wheel hub is scanned and the second FF2 supplies an output to open gates 83, 85 when the wheel web and rim is scanned. The output of each radiation detector, e.g. RD1, is applied via an electronic chopper circuit 78, controlled by square wave generator 79, and A.C. amplifier 80 to gates 82, 83. The signal is then detected and passed via limiting and comparison means (see Group XXX) to recording and signal means 97. Each detector, Fig. 4, comprises an inclined detector assembly D1 including infra-red responsive element 20, reflecting element 18 and infra-red transmission window 19. Radiation is received by the element when the presence of a train detected by the magnetic detectors results in the energizing of a solenoid SS1 which lowers a shutter S1. The shutter is held in its open position until the train has left the detecting section of track or when the train has passed the detectors and before it leaves the detecting section if the light energy passing through the shutter and detected by photo-cell LM1 has an intensity which may damage the infra-red detecting element.

Title: Refrigeration system
IPC: F25B41/06
Filed: 1972-08-04
Abstract: 1352469 Refrigeration systems STATHAM INSTRUMENTS Inc 4 Aug 1972 [12 Aug 1971 18 July 1972] 36598/72 Addition to 1331360 Heading F4H [Also in Division F1] A refrigeration system comprises an evaporator 1 exposed to the air to be cooled, a condenser 5 kept cold for example by solid carbon dioxide, a pipe 16 conveying vapour from the evaporator to the condenser via a turbine motor 8, and a pipe 18 for conveying condensed liquid from the condenser 5 to the evaporator, under the control of a pump 6 driven by motor 7. The exhaust vapour from pump motor 7 and fan motor 8 is returned by pipe 14 to the condenser. A float valve 9 connected between the manifolds 25, 26 of the evaporator opens when the liquid level falls and allows vapour under pressure to pass to the pump motor 7 causing the pump 6 to pump more liquid via pipe 18 to the evaporator until the liquid level reaches a predetermined level. When the temperature of the condenser is made low by dry ice the pressure in it is zero. Vaporization in the condenser causes a pressure difference between pipe 16 and pipe 14 sufficient to overcome the action of a spring in valve 10, which opens and allows vapour to pass to the turbine motor 8 of fan 3. The fan 3 is mounted in a hood surrounding the evaporator 1 and serves to circulate air over the heat exchanger tubes 4 and in the space to be cooled. The operation of the fan can also be controlled by a thermostat bulb in a remote position actuating a valve in line 16.

Abstract: 799,218. Fish, heading. ARENCO AKTIEBOLAGET. Nov. 30, 1956, No. 36741/56. Class 28 (2). A fish to be headed is pushed lengthwise head first up to an automatically adjusted abutment 6 of a rotating helical surface 27, 39, which bears down on the fish body in accordance with its thickness and then adjusts the position of the abutment 6 so that the head is positioned for economical cutting off just behind the branchial arch. Each fish is hand-placed in a container 22 with its head resting in another spaced container 24, the containers comprising seriesmounted on endless chains 18 and 20 which carry the fish to a fixed heading knife located in the space between the containers 22 and 24. In accordance with the rise or fall of the surface 27-29 on the fish thickness a pin 42 on the limb 13 of a bell-crank 36 rocks a lever 11 about its fixed pin 22 whereby a pin 7 rocks a link 21 pivoted at 29 to slide a rod 15 so that its attached abutment 6 slides along 19 to the desirable adjusted position. The abutment 6 is adjusted at a rate of twice the amount of rise or fall of the feeder 27-39. The tip 39 provides a leading edge to pass over the fish body until the helix 27 actually engages and pushes the fish forward. The helix may have ribs 25 to prevent slip over the body. The abutment 6 is provided with a guide 9 to direct the head against 6. The helical surface is rotated by a sprocket chain 40.

A portable pneumatic tapping- machine for re-tapping holes comprises a vane-type motor (not shown) driving the chuck 13 through a reduction gear (not shown) and a non-rotatable sleeve 3 constituting the handle of the machine and which is slidable axially, relatively to the chuck, in both directions against the action of pre-loaded spring means 5 tending to return the sleeve to an intermediate, neutral position, the sleeve controlling, by its forward and rearward movements from the neutral position, the supply of compressed air to effect respectively forward and reverse drive of the motor. A spring unit 5, surrounding the motor, acts on each side of a ring 4 fixed in the bore of the sleeve, and comprises rings 6, 7 joined by pins 8. Plungers 9, guided in holes in the rings 6, bear against the ring 4 and are biased by springs 10 which are located on pins 12 on the rings 7. An axial slot 15 (Fig. 4, not shown) in sleeve 3 is engaged by a key on the body of the machine to prevent rotation of the sleeve. The inclined part of a further slot 16 in the sleeve engages a projection 18 on a valveoperating yoke 17, which is thus rotated in either direction depending upon the direction of movement of the sleeve. A spring 20, Fig. 5, connects the yoke to the rotatable valve sleeve 22.

Abstract: A permanent magnet material having a modified strontium ferrite base and containing 7 to 18% by weight of strontium oxide and from 0.1 to 2% by weight of strontium sulphate is obtained by sintering a strontium component, containing 89-93% by weight of strontium carbonate and 1 to 10% by weight of metal sulphates, with iron oxide. Preferably, 10-25% by weight of said strontium component is mixed with iron oxide, the mixture is calcined in an oxidizing atmosphere at a temperature of 900-1400 DEG  C., the calcined clinker is cooled, ground and compacted into a formed body and the formed body is sintered in an oxidizing atmosphere at a temperature of 900-1350 DEG C. The strontium component may be prepared from the mineral celestite by reducing the sulphates contained therein to sulphides reacting the sulphides so formed with a water-soluble carbonate and separating the precipitate formed. Various impurities in the modified strontium ferrite, especially sulphates, have a beneficial effect on the magnetic properties. In addition, various additives such as flux agents, grain growth inhibitors and certain metal oxides may be added.  The permanent magnet material is preferably made up as follows, all percentages are by weight:- <TABS:0995374/C1/1> Remainder Fe2O3.

Concurrently an execution unit is executing previous instructions. The instruction buffers are refilled as they become empty, unless this conflicts with execution of a previous instruction or operand fetches, which have priority. An exception is when both buffers are empty in which case instruction fetch has priority.

Liquid lubricant L is contained in a reservoir 3 and a liquid supply tube is provided to conduct the lubricant through passages 28, 27 to a nozzle with a conical tip 26 and a Venturi tube 31. As the air passes through the Venturi tube it draws lubricant L through the tip 26 forming an aerosol. The aerosol passes through a converging passage 34 and through passages 38, 39, 40 to a space 12 above the reservoir 3. As the aerosol leaves the passage 34 unpressurized air from a chamber 19 is entrained in the aerosol stream to form a combined aerosol.
