Title: Improvements in or relating to fuel vapourising systems for internal combustion engines
IPC: F02M21/10
Filed: 1936-05-15
Abstract: 475,361. Vaporizers; refrigerating. ELECTROLUX, Ltd. May 15, 1936, No. 13864. Convention date, May 16, 1935. [Classes 7 (ii) and 7 (iii)] [Also in Group XIII] A vaporizing system connected to the suction intake of an engine driven by liquid fuel comprises an evaporator wherein liquid fuel vaporizes with the production of useful cold, means to utilize the cold thus produced, an air-fuel vapour heat-exchanger disposed between the evaporator and a vaporizing or atomizing device interposed between the heatexchanger and the intake to vaporize fuel not vaporized at the temperature of the heatexchanger. A carburetter 13 draws its air supply through passages 12, 11 and narrow passages 9 in a heat-exchanger 8 through which the combustible mixture flows to the engine after having traversed an evaporator 14. The cold produced in the evaporator 14 is transferred by a coil 15 to a coil 16 in a refrigerating cabinet 17, and the amount produced is controlled by an air inlet valve 18 which may be actuated by a bellows 19 communicating with a heat-sensitive capsule 20 in the cabinet 17. The heat-exchanger 8 is inclined to permit unvaporized fuel to drain on to baffles 6 in the intake 5 which is surrounded by a heating jacket 7, any remaining liquid fuel being vaporized by falling on to a hot spot on the lower side of the induction manifold. Alternatively, the fuel may be sucked up from the end of the heat-exchanger into the intake 5 if the exchanger is below it. If the fuel drains into a float-controlled chamber, this may be opened to the atmosphere when the throttle is opened and provide fuel for acceleration. As shown in Fig. 5, two stage evaporation is used, the carburetter 13 delivering first to a chamber 40 where evaporation of the more volatile constituents produces cold for making ice and then to an evaporator 42 suitable for cooling a room, e.g. a refrigerator van. The evaporator 42 is flanged at 43 and may be disposed in a stream of warm air to ensure the evaporation. The cold control valve is disposed between the two evaporators 40, 42. The carburetter and evaporators may be disposed in the front of and at the top of the body of refrigerator van &c.

IPC: F02B53/00
Filed: 1918-08-27
Abstract: 131,176. Bergasse, P. H. Aug. 27, 1918. Fixed-abutment type; balancing moving parts; cooting parts; packing drums, vanes, etc.; working-fluid supply.-A rotary internal-combustion engine comprises two or more power cylinders of the type having sliding-rocking vanes and supplied with working fluid from a rotary pump of the same type, which receives fan-compressed air delivered through the centre portion of the engine for cooling. A fan 37 at one end of the casing delivers air through the interior of three rotors to the other end of the casing, where it is conducted through a rotary valve 6 to the right-hand cylinder. Here the air is further compressed and delivered through ports in the rotary valve 6 and an adjustable sleeve 5 to passages 7 and valves 12, where it is carburetted and supplied to the other two cylinders. The compressed air from the valve 6 presses down the stem 11 of the valve 12, thereby opening needle valves N and admitting fuel supplied by a duct 13. Ignition is effected by sparking-plugs 14, and the exhaust passes out through ports 1. The sliding-rocking vanes 21 are balanced by counterweights 74, have packing members 20, 22, and rotate about fixed crank-pins 51; they protrude through rocking members 19 housed in the rotors 3, which are cut away on the explosion side of the vane to expose a greater surface of the vane. Triangular packing- rings 67 are fitted in grooves in the rotor and stator flanges 33, 34, and a ring 0 is clasped round the periphery of the rotor. The engine is started by turning a pinion p gearing with a wheel 65 secured to the rotor shaft, which transmits the drive through gearing 54, 55 to a shaft 60. Surplus air from the valve 6 may be used as a scavenging charge or stored in a reservoir for starting purposes. The portion 28 of the casing where the rotor contacts with it is made of the same curvature as the rotor.

Title: Improvements in or relating to dynamo electric machines
IPC: H02K3/24
Filed: 1950-06-06
Abstract: 682,340. Cooling dynamo-electric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 6,1950 [Aug. 12, 1949], No. 14072/50. Class 35. At least one member of a high voltage machine is cooled by passing gas above atmospheric pressure through ducts disposed axially in the conductor slots and over a cooler. The other member may be gas or liquid cooled. As shown in Fig. 1, hydrogen under pressure leaving the radial duct 7 at the centre of the stator core flows eircumferentially towards one of a pair of axially extending coolers 31 disposed fairly close together in the upper part of the machine, passes circumferentially across one cooler and then in opposite directions axially along the space between the two coolers to the inlet of one of the fans 35 at each end of the machine. Of the gas discharged by these fans, some traverses axial ducts 47 in the stator core and teeth, some through ducts provided in the conductor slots of the stator and some through rotor conductor slots, the rotor conductors 44 being hollow or U-shaped. In Fig. 8, partitions 52, 53 enable different coolants to be used in the stator and rotor. Hydrogen flows axially along the rotor slots as in Fig. 1, but in this instance returns along the airgap after traversing apertures 46 in the slot wedges to one of a pair of vertical coolers 61 placed at each end of the machine. For the stator, gas or a liquid such as transformer oil may be employed, flowing axially from each end of the machine to a central duct as before but then passing to a pump and cooler in the base of the machine before returning to the stator ends. Other coolants mentioned are liquid compounds of fluorine and carbon, also sulphur hexafluoride. The stator end windings have supports 17 as shown in Fig. 1. Reference has been directed by the Comptroller to Specification 667,609.

Title: Improvements in or relating to electrical systems containing x-ray or like apparatus
IPC: H05G1/70
Filed: 1920-05-25
Abstract: 143,865. Pilon, H. Aug. 19, 1915, [Convention date]. Vacuum apparatus, arrangements of.-A thermionic valve is used in the place of an ordinary cathode valve to obtain a unidirectional current supply through an X-ray tube or other apparatus. The valve tube K, Fig. 1, with a cathode e heated by a separate battery P or otherwise may be connected in parallel with the X-ray tube R. As the current through the valve K depends upon the temperature of the cathode e, a number of circuits R', R<2>, R<3>, Fig. 2, containing apparatus for different types of work such as high power tubes and low power tubes may be supplied from the same source S, the current being regulated by thermionic valves K<1>, K<2>, K<3> in series in each circuit. A common shunt valve K can be used. Alternatively, both half waves of the current from the supply S may be utilised and the condensers dispensed with by using opposing valves K<1> - - K<4> in the different parallel circuits R<1> - - R<4> as shown in Fig. 3.

Title: An automatic grinding machine for film resistors
Inventor: BEYER HELMUT
IPC: B24B49/00
Filed: 1965-04-05
Abstract: 1,109,522. Grinding resistors. ELEKTROMAT VEB. 5 April, 1965, No. 14311/65. Heading B3D. In an automatic machine for making resistors by grinding a helical groove in a conductive coating on a non-conductive core, a vibratory feeder 1 delivers blanks into a feeder tube 2 equipped with a photo-electric detector 3. The bottom horizontal end of the tube 2 is attached to a slide 11 traversed, against a spring 22, through gearing 21 comprising rack and magnetic clutch 18 by a Ferraris motor 20 coupled to a tachometer generator 19. Adjacent the end of the tube 2 the slide 11 carries loading mechanism comprising a loading arm with a gripper 4, a tension spring 5 and a thrusting plunger solenoid 6. The loading mechanism places the blank between sockets 8 of spindles 7, 7<1> on the slide 11. The spindle 7<1> is advanced by a spring 9 when the withdrawing solenoid 10 is de-energized, thus gripping the blank. The spindles 7, 7<1> are geared together by a spur gear transmission 13. The spindle 7 is driven by a motor 15 through a change-speed gear-box 17 and a magnetic clutch 16. The spindles 7, 7<1> have electrical contacts 14, 14 for transmitting signals to a unit 12 for measuring the resistance during grinding and for controlling the machine. A grinding unit is adjustable by a milled nut towards the spindles 7, 7<1> in the direction of axis A-A and can be turned about that axis. The grinding unit comprises a support and a rotatable system comprising a motor 24, a deflectable grinding head including a disc 25 and a pressure generating system comprising a compression spring 31, a thrusting plunger and solenoid 23 and a tension spring 26. The spring 31 acts on the grinding head in conjunction with the plunger of solenoid 23 restrained by spring 26, the plunger being linked to a fork member in a slot 32, to swing the grinding head into contact with the blank when the solenoid 23 is energized. Adjustable contacts 27, 28 serve for rejecting after grinding resistors which attain the required resistance value before a certain minimum length of blank has been ground and those which have not attained the required value when the full length has been ground. When the measuring bridge is balanced the unit 12 de-energizes magnetic clutches 16, 18 and solenoid 23 and energizes solenoid 10, so that the spindles 7, 7<1> and the slide 11 cease to be driven, the grinding disc is withdrawn from the workpiece and the spindle 7<1> is retracted. The workpiece falls into a sorting shaft below the grinding disc 25 and is either ejected by a gate. 30 operated by a solenoid 29 or falls down the shaft into a bin or conveyer.

Filed: 1935-05-16
Abstract: 454,454. Photographic roll-film cameras; shutters. KILFITT, H., 28, Markgrafenstrasse, Schwelm, Westphalia, Germany. May 16, 1935, No. 14384. [Class 98 (i)] The film feed and shutter operation are controlled automatically by a spring mechanism, a release slide liberating a mutilated segment under tension so that it actuates the shutter mechanism whilst thespringmechanism is held by a stop lever. The film feed comprises two thin discs 2 mounted on a spindle 2a, one of the discs having a pin 3 which engages a stop plate 4 on a mutilated gear 6 in mesh with a pinion on the spindle of the shutter plate. The spindle 2a is connected to a brake mechanism comprising an escapement 63 and a pallet 64. which may be held stationary by a pivoted lever 66, the other end of which is held in a slot in the release slide 28. The spring mechanism is contained in a detachable housing in the side of the camera. When the driving spring is tensioned, the feed roller is rotated and advances the film, the pin 3 engaging the plate 4 to rotate the gear 6 and tension the shutter disc. A cover flap prevents an exposure being made. When the knob 14 is depressed, the release slide 28 swings away the cover flap, locks the braking mechanism 63 by the lever 66, and moves the stop plate out of engagement with the pin 3 so that the exposure is made as the shutter runs down. Release of the knob 14 removes the brake, and the film is fed forward again and the shutter tensioned. The shutter mechanism, Fig. 5, operates under the control of the release slide 28. When the gear wheel 6 rotates, a pin 58 on its underpart bears against a lever 59, the rounded back of which fits in a recess of a lever 80. The toe 81 of the lever 80 is adjustable on a cam 82 mounted on a spindle 12 which is adjustable from the outside to vary the tension of the spring 11. The pin 58 rotates the toothed segment 83 to tension the spring 88 and rotate an escapement wheel 85 which has been brought out of the range of its pallet 86. The shutter disc is mounted on the spindle of a disc 76 which has a stop pin 73. Upon the release being effected, the pins 8 returns and the spring 11 brings the escapement wheel 85 into engagement with the pallet 86, whilst the pin 73 is brought by the spring 11 into engagement with the arc 89 of the segment 83. The segment 83 slowly slips back under the control of the escapement until the pin 73 slides off the arc 89 and completes the exposure by rotation of the shutter disc.
