Title: Sterilising and filling bottles
Inventor: BURTON HAROLD
IPC: B67C3/26
Filed: 1964-10-30
Abstract: 1,128,323. Bottling. NATIONAL RESEARCH DEVELOPMENT CORP. 26 Oct., 1965 [30 Oct., 1964], No. 44485/64. Heading B8T. In a bottle &c. sterilizing and filling machine, a bottle 1 is sterilized within a closed container 2 having inlet and outlet passages for steam. First the outside of the bottle 1 is steam-heated, while the inside is subjected to the vacuum of a steam-ejector 6. Then steam is admitted to the inside of the bottle 1. After sterilization, a plunger 21 and a valve head 18 are lowered, so that a spring 17 moves a tube 14 downwards. A floating valve sleeve 22 is thus allowed to move downwards and seat on the seal 8. Continued downward movement of the plunger 18, 21 &c. separates a valve seal 27 from the floating valve sleeve 22. As the plunger 21 moves on downwards, the tube 14 seats on a seal 23 of the now stationary valve sleeve 22, so that its motion is arrested. The valve head 18 moves on downwards, and separates the valve seal 27 from the valve seat 22, so that milk &c. in a container 12 flows through the tube 14 &c. into the bottle 1. Steam in the bottle is condensed, and the bottle is filled. The plunger 18 &c. is drawn upwards again to the position shown. In one modification, the floating valve sleeve (22a) does not contact the seal (8a) but engages directly with the bottle top. Thus, if a bottle is not present, the liquid valve cannot open. In another modification, Fig. 3 (not shown), provision is made for caps (35) to be inserted through a passage (37, 39) into the filler head, which is in two horizontally separated parts. The caps are sterilized before being positioned over the bottle neck, for capping by raising the bottle against the cap. In yet another modification, Fig. 4 (not shown), the floating valve sleeve is omitted. Instead three concentric circular flexible seals (51-53) are provided in the filler head. When the valve head (18) moves downwards, a flange (54) at the top of the tube (14c) engages the filler head (50) to arrest downward movement of the tube, and open the liquid valve (47, 49).

The potentials applied before, at, and after the development "nip" may correspond to less than the background potential, a potential between the back ground and image potentials, and a potential above the image potential respectively, to urge toner particles away from sleeve 22, assist development, and prevent post-development powder clouds respectively.

Title: Internal combustion engine shut off system
IPC: F02M1/00
Filed: 1964-11-03
Abstract: 1,035,640. Starting, stopping I.C. engines. B. WALKER. Nov. 3, 1964, No. 44800/64. Headngs FIB and F1K. [Also in Division H2] A system for stopping an I.C. engine is operable to cut off the fuel supply for idling and, after a time delay, to turn off the engine ignition. The system is actuated by a key 70. Clockwise movement of which from the "off" position shown to the "on" position moves a rod 53 to the right thus closing the ignition circuit through contacts 38, 39 and moving a diaphragm 52 to the right, air being sucked into the chamber housing the diaphragm through an inlet 57. This movement of the key also closes a switch 34 to energize a solenoid 28 which withdraws a needle valve 18 from its seat and opens the engine idling jet 20. On moving the key to the "off" position, switch 34 is immediately opened to de-energize the solenoid 28, valve 18 closing the idling jet under the action of a spring 21. A time delay occurs before the contacts 38, 39 part, since air escapes slowly from the diaphragm chamber through outlet 56 under the control of valve 55. The time delay may be at least two seconds to allow the engine to stop before contacts 38, 39 part. Inlet 57 may communicate with a supply of liquids or a gas other than air. Outlet 56 may communicate with the atmosphere or a source of fluid pressure, for example a compressor driven by the engine. In the latter case, the diaphragm does not move to the left after the key has been moved to the "off" position as long as the engine is running, and so the engine, when installed in a vehicle, can be used as a brake with ignition maintained and the fuel supply turned off.

Abstract: 1,023,289. Blasting. STANDARD TELEPHONES & CABLES Ltd. Nov. 15, 1963, No. 45227/63. Heading B3D. An abrasive blasting machine includes a workpiece mounting member surrounded by an elastic sleeve for locating a mounted workpiece, the sleeve being advanceable along the mounting member to compensate for wear of the sleeve. A semi-conductor cell 5 consisting of a semi-conductor element 6 fastened between metal plates 7, 8 with a lead wire 9 extending from the plate 8 is held to the surface 3 of a pedestal 1 by suction applied through bore 10 in the pedestal. The vacuum is conveniently obtained from the vacuum supply necessary for coupling to a hood for extracting the abrasive. A nozzle 11 directs abrasive on to the semi-conductor element 6 while the pedestal 1 is rotated. The pedestal is protected from abrasion by a closefitting elastic sleeve 2, e.g. of plastic. The sleeve extends proud of the surface 3 to form a locating lip for the workpiece. When the sleeve wears down it is advanced along the pedestal either manually or automatically.

Title: Computer controlled sonic fuel system

Abstract: 1409504 Fuel injection control systems A K THATCHER 28 Sept 1973 [29 Sept 1972] 45591/73 Heading G3N [Also in Divisions F1 and H3] The fuel supply to the carburetter 12, Fig. 1 of an I.C. engine, automatically controlled by a valve 22 in accordance with signals representing the engine speed and the inlet manifold temperature and pressure combined in a computer 24, is atomized by a sonic dispersion unit 32 before entering the carburetter to obtain uniform mixing of fuel and air. The sonic unit consists of a vibrator comprising a horseshoe electromagnet 38, Fig. 2 with drive coils 42 fed from an oscillator network including amplifier 34 with feedback 36, whose frequency is adjusted to the resonant frequency of a horn 46. The active surface 44 of the vibrator is coupled to the horn to concentrate the vibrations on a smaller active surface 48. Fuel is supplied via a tube 98, Fig. 5 resting in a groove on the outside of the narrower cylindrical section 51 of the horn and ending short of the active surface 48, thereby producing a thin film of fuel over this surface. Alternatively the fuel tube 98 is located inside the horn 48 ending in a group of holes on the active surface. The fuel tube may be duplicated with one tube feeding larger holes when the engine is on load and another tube feeding smaller holes for use when the engine is idling, the changeover being effected by an engine speed signal. In an alternative arrangement, Fig. 10 fuel is supplied by two injector nozzles 134 directed on to the active surface 48 of the horn 46, protected from the air stream fed through inlet hole 132 by a shroud 136. The fuel computer 24, Fig. 11 controls the fuel supply by varying the duration of the injection pulse in accordance with engine speed and inlet manifold temperature and pressure. The pressure sensor 30 varies the coupling between the windings of a transformer 138, to produce an A.C. pressure signal from amplifier 150 which is rectified and fed to junction 180. The temperature is sensed by a thermistor 28 and produces a D.C. voltage which is integrated at 166 and also fed to junction 180. The integration process is cyclically reset by pulses from a flip-flop 192 triggered by a pulse train 188 whose frequency is proportional to engine speed: The circuitry produces pulses synchronous with the engine speed, whose width is proportional to the measured pressure and inversely proportional to the measured temperature. These pulses are fed to the solenoid winding 200 of the fuel injection valve 22. Initial adjustment is effected by a potentiometer 178. The latter part of the computer may be duplicated to control two injector nozzles 134, which may be fed with different fuels, the fuel ratio being determined by the settings of potentiometers 178.

Automatic gain control of one stage of a selective transistor amplifier is of a type which reduces the gain of the transistor by reducing its collector current and of an adjacent stage is of a type which reduces the gain of the transistor by increasing its collector current. By this means changes in input and output impedance may be made to cancel so that the bandwidth remains constant or varies in a desired manner. To avoid cross-modulation in a preceding stage it may comprise two transistors (Fig. 2, not shown) having their inputs in antiphase and their outputs in parallel so that the two outputs cancel when the stage is balanced. The gain of one transistor is then controlled to vary the extent of cancellation.
