Title: Improvements in or relating to the mechanical handling of bottles or other containers
IPC: B65B43/50
Filed: 1954-06-22
Abstract: 769,209. Conveyers. SCHOFIELD, H. P. Sept. 21, 1955 [June 22, 1954], No. 11600/54. Class 78 (1). A rotary turn-table 26 simultaneously loads containers into the input end C and extracts them from the output end B of a conveyer system 11, 12, 13. The turn-table is rotated by either a manually actuated ratchet-and-pawl mechanism or a power drive (not shown), and is provided with spring-loaded feeler means (Figs. 4-6, not shown) which lock the turn-table unless a container of predetermined shape and size is located in the positions A and/or B. The conveyer system which may form part of a heatexchanger of a bottle treating apparatus comprises endless belts 11, 12, 13 moved intermittently in the direction of the arrows under the control of trip mechanism (not shown) which stops the conveyers when a container arrives at B, and restarts them when the turntable has transferred this bottle to position A. Belts 11, 12 are driven respectively by rollers 15, 19, the diameters of which increase from the input end of the system to the other so increasing the speed of the belts and ensuring that when a container is fed into the system another container is at the opposite end ready for extraction. The containers are guided by plates 14 when they are transferred from one conveyer run to the next.

Title: Improvements in or relating to cathode-ray tubes
IPC: H01J29/52
Filed: 1935-04-15
Abstract: 455,237. Cathode-ray tubes. WILSON, J. C., 24, Whitworth Park Mansions, Manchester, and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. April 15, 1935, No. 11636. [Class 39 (i)] The modulated cathode-ray of a tube for television &c. is produced by constructing a cathode 2 so that its emission varies over its surface, forming an electron image of the cathode 2 on an apertured electrode 4 as by a coil 3 and deflecting the image over the electrode 4 to vary the part of the image received by the aperture 5 therein. The aperture 5 forms the effective source of the ray which may subsequently be acted on by fasciculating, accelerating and deflecting electrodes. The cathode 2 is a strip heated by electric current and variably activated so that its emission varies with the distance from one end according to the desired modulation characteristic. The image of the cathode strip 2 is deflected lengthwise over the electrode 4 by plates 6 or magnetically.

Title: Improvements in or relating to Hydrostatic Transmission by Gas Turbine.
IPC: F02C3/113
Filed: 1968-03-11
Abstract: 1,187,162. Gas turbine engines. ALFRED TEVES G.m.b.H. March 11, 1968 [May 24, 1967], No. 11724/68. Addition to 1, 007, 292. Heading F1G. The invention relates to a hydrostatic transmission by a gas turbine engine, the gas turbine being mechanically separate from the compressor of the engine, the turbine shaft and the compressor shaft being hydraulically connected by the relatively rotatable parts of the pressure-medium pump of the hydrostatic transmission. The drive connection between the compressor shaft and the corresponding part of the pump, and the drive connection between the turbine shaft and the corresponding part of the pump, each comprise a gearing stage. In Fig. 1 the compressor 1 supplies air to combustion chamber 6, combustion gases from which pass to turbine 3. The compressor shaft 15 is connected through gearing 11 to shaft 9a of the part 9 of the hydrostatic transmission pump 8 and the turbine shaft 16 is connected through gearing 12 to a shaft 10a of the part 10 of the pump 8. The whole transmission system is shown diagrammatically in Fig. 2 in which the compressor and turbine are indicated at 1, 3, the transmission pump at 9, 10 and the transmission motor at 18. At idling there is no output from the pump 9, 10, the turbine 3 driving the compressor 1 through the pump 9, 10 which acts as a coupling. When the accelerator pedal 24 of the control unit 23 is depressed hydraulic pressure acts through lines 29, 26 to open the valve 22 whereby hydraulic fluid can pass from the pump 9, 10 to the motor 18 the shaft 20 of which is connected to the wheels of a vehicle. At the same time fuel supply to the combustion chamber 6 is increased. The motor 18 is controlled by the device 19 in response to pressure of fluid in the line 25. The speed of output shaft 20 is sensed by the device 27 which is connected to the control unit 23.

Title: Improvements in and relating to apparatus for dispensing measured quantities of liquid
IPC: B67D3/00
Filed: 1930-04-14
Abstract: 352,953. Delivering measured quantities of liquids. FISCHMAN & SONS, I., 10th Street, Philadelphia, U.S.A. April 14, 1930, No. 11811. Convention date, July 31, 1929. [Class 106 (v).] Measured quantities of beverages &c. are delivered by a rotatable drum 50 from a receptacle B, the fluid being kept in circulation by providing passages 43, 43<1> between the receptacle and drum at each end of the latter and by the use of a constantly rotating impeller 61. A transverse partition 68 in the lower part of the receptacle also improves the circulation. Through a door 15 the attendant lifts the handle 107 of a lever 106, releasing a catch 109 from a notch on the shaft 73 of coinfreed mechanism 72 and bridging contacts 116, 1161 by a spring-strip 117. The motor 66 is thus started and drives the impeller 61. The spring-pressed armature 113 of a solenoid 112 prevents the lever 106 from relocking the shaft 73. After prepayment at the mechanism 72, the handle 75 is operated and through bevel-gearing 77, 56 turns the drum 50 to discharging position. The port 59 is brought into register with the air vent 45 which, in conjunction with the impeller 61, causes the discharged fluid to be of a creamy consistency. On the release of the handle 75, a spring 78 returns the drum to its filling position. When the liquid in the receptacle is exhausted the stem 97 of the float 98 by lifting a lever 95 displays the word " Empty through a window in the casing 99 and at the same time closes a circuit through the contacts 102, 102<1> and strip 103. The solenoid 112 is thus energized, the armature 113 withdrawn and the lever 106 relocks the shaft 73 ; the switch 116, 117 is also opened and the motor 66 and impeller 61 stopped. Cooling fluid may be circulated through a coil 80 around the receptacle, there being a motor-driven compresser in the base of the apparatus. A second coil, in series with coil 80, may be lodged within the container B. A thermostat 90 maintains the temperature constant. An electrically-heated coil may be situated in the base of the receptacle, its terminals passing through the wall for connection to a current supply. A cup-dispenser may be arranged at the side of the apparatus, and a receptacle for empty cups mounted beneath. A driptray 18 surrounds the base of the container.

Title: Improvements relating to the introduction of magnesium into molten iron
IPC: C21C1/10
Filed: 1953-05-05
Abstract: Magnesium is introduced into molten iron by bringing a sintered material the pores of which have been impregnated with magnesium into contact with the molten metal.  The sintered material may be made from iron powder, ferro silicon, or a ceramic material and may have a pore volume of 40-60 per cent.  The impregnated material may be introduced into a hollow plunger, the aperture in which should be large enough to allow movement of the body, and then thrust below the surface of the metal, or the body may be fixed to the end of a rod, e.g. by a thread.  After use the sintered body may be again impregnated with magnesium, but with an iron body it should be heated in hydrogen before impregnation.  In a modification the pores in part of the surface, e.g. at the top, may be closed by graphite so that the escape of magnesium is controlled.  Magnesium alloys may be used, e.g. an alloy containing 1.25 per cent aluminium, 0.1 per cent beryllium and the balance magnesium.  Specification 630,070 is referred to.
