Title: A new or improved container filling machine
IPC: B67C3/08
Filed: 1940-01-26
Abstract: 540,762. Valves. LIQUID CARBONIC CO., Ltd. (Kantor, J.). Jan. 26, 1940, No. 1644. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 23, 1940. ] [Class 135] [Also in Group XVII] A machine for filling containers with carbonated beverages or with other liquids has " counter-pressure " provided from open-bottom containers 47, 42, 38, Fig. 1, partially immersed in water in a container 2, this pressure being applied at the lower end of the filling tube in the bottle &c. to be filled by introducing it through a filling head shown in Fig. 2 so as to tend to counterbalance the pressure of the incoming liquid. The counter-pressure is introduced at a threaded stem 25 and passes down a slidable tube 21 which, when the bell 30 is pressed upwards by the bottle mouth, leads the counter-pressure air or gas in and around the outside of filling tube 7. Also this counter-pressure reaches the upper side 11 of a diaphragm 10 through which a filling-valve 8 is kept open until removal of the filled bottle releases this pressure and closes valve 8. The connecting at various appropriate times of the " counter-pressure " containers 47, 42, 38 to the filler head thus establishes various filling pressures namely the pressure at which the liquid is delivered from its supply container less the counter-pressure. The height of container 47 is adjustable. Containers 1, 2 and the head 33 rotate together by virtue of being mounted on the same rotating platform. Chambers 47, 42, 38 are fixed, being carried on a fixed sleeve 89, Fig. 3, so that relative movement between valves 85 and 70 and the head 33 is secured. Air is supplied to the chambers through tube 46 ; it leaves cylinder 47 through a tube 59 and valve 70 which consists of a tube 73 spring-pressed against the underjaw of head 33. Thus, the filling-head 3 is connected by pipes 36 first to cylinder 47 through valve 70, then to cylinder 38 directly through passages 35, then to cylinder 42 through valve 85. The counter-pressures are measured by the heights C, B, A<SP>1</SP>, Fig. 1, which are the heights on the columns of water these pressures will support. The filling head proper is measured similarly by the height from the lower end of the filling tube, i.e. valve 8, to the free level A' in tank 1.

Title: Improvements in servo-motor devices applicable particularly to centrifugal speed governors
IPC: G05D13/00
Filed: 1947-01-20
Abstract: 631,816. Fluid pressure servomotors. AKTIEBOLAGET ATLAS DIESEL. Jan. 20, 1947, No. 1805. Convention date, Oct. 29, 1946. [Class 135] [Also in Groups XXVI and XXXIV] A fluid-pressure servomotor comprising a singleacting piston &c. interposed in a spring system, the outer ends of which are in contact with fixed abutments is controlled by a valve including two relatively movable members for controlling the flow of working fluid to and from the piston cylinder, one of said members being actuated by a governor, e.g. a speedgovernor, whilst the other is connected to the spring system between a fixed abutment and the piston. The embodiment shown is applied to an internalcombustion engine for controlling the fuel supply thereto in accordance with its speed and comprises a casing 3, housing an engine-driven cup member 22 formed with a recess carrying a single governor weight 25 loosely mounted between the cup and the lower end of a rod 29 which supports a valve plunger 8 arranged for rotation with the cup and capable of axial movement. The plunger 8 co-operates with a ported sleeve 6 formed with a flange 18 which provides an abutment interposed between springs 20, 21 whose other ends abut the lower end of the servo-cylinder 2 and its spring- loaded piston 13 respectively. Ports 7 in the sleeve 6 communicate with a duct 4 supplied with pressure oil, whilst ports 12 coacting with a land 11 of the plunger control the flow of oil to the underside of the piston and the discharge therefrom through the hollow piston rod 15 which is operatively connected to the fuel valve. The working range of the governor is adjustable by a spring 9 disposed between a fixed collar 33 and an adjustable collar 31 movable by a forked lever 36 secured to a manually-actuated shaft 35. To increase the operational speed of the engine, the shaft 35 is rotated anti-clockwise to increase the loading on the spring 9, and clockwise to decrease the engine speed. In operation, on a fall in the set engine speed, the plunger 8 will move downwardly to uncover the upper edges of the ports 12 to drain the cylinder 2 and hence permit the downward movement of the spring-loaded piston 13 and an increased opening of the fuel valve. Conversely, a rise in the set engine speed uncovers the lower edges of the ports 12 to permit the supply of oil to the cylinder 2 to raise the piston 13 and hence decrease the opening of the fuel valve. The springs 20, 21 operate to move the sleeve 6 to follow up the movements of the plunger 8. The servomotor may be used for controlling the main valves for gas, steam or hydraulic motors and for operating braking devices and is suitable for use with either liquid or gaseous fluids.
