Patent GB-2037255-A (GB)
Title: Metered dispensing of liquids
IPC: G01F11/08
Filed: 1978-12-12
Abstract: A container 1 from which liquid is dispensed has a metering chamber 15 arranged at its mouth. A metering device is arranged to cooperate with the outside of this metering chamber to control the amount of liquid allowed to flow out. The flow can be controlled either by determining the time for which the metering device opens the metering chamber, or by constructing the metering chamber as a pump chamber of a specified volume so that the metering device pumps the liquid out of the chamber and therefore dispenses a predetermined volume. In the second method, the metering chamber includes an axially compressible bellows portion 19 which forms a pump chamber. Non-return valves 18, 22 are provided at both ends of the pump chamber, and the metering device comprises plates on either side of the bellows section which can be drawn towards one another to squeeze the bellows section 19. <IMAGE>

Title: Pulsed current supply for electric fence
IPC: H05C1/04
Filed: 1979-05-12
Abstract: An electric fence is supplied with intermittent pulses by a semi- conductor circuit in which all the active components are non-conducting between pulses.

Patent GB-2089020-A (GB)
Title: Device for use in a cistern containing liquid for the storage of thermal energy
IPC: F24D3/10
Filed: 1980-02-12
Abstract: When storing thermal energy in a storage tank (1) for heated fluids it is advantageous to maintain thermal equilibrium in the fluid when filling and draining the tank. At thermal equilibrium the temperature in the fluid rises continuously from the bottom of the tank (1) to the surface of the fluid. The tank (1) is filled by means of at least one tube (2, 9). To prevent disturbance of the thermal equilibrium when filling the tank the mouth of the tube (2, 9) is arranged within a chamber (6), placed in the tank, which chamber has a length of the order of half the depth of the tank. The side walls of the chamber (10, 11) are perforated to allow the fluid to flow through the said walls. When filling the tank (1) with a fluid having a temperature of less than the average temperature of the fluid in the tank (1) the chamber (6) is arranged in the lower half of the tank. Similarly, when the temperature of the fluid is higher than the average temperature of the fluid in the tank, the chamber (6) is arranged in the upper half of the tank (1).

Title: Fluid flow control apparatus and method
IPC: G05D7/06
Filed: 1981-02-13
Abstract: A method and apparatus for maintaining a constant rate of flow of fluid in a flow line (2) in which an electrically operable valve (1) in the flow line is cycled repeatedly such that it is open during one part of the cycle and closed during the remainder of the cycle. The fluid flow is controlled by varying the opening and closing periods during each cycle and this is achieved either by varying the switching frequency at a constant on/off ratio or by varying the on/off ratio at a constant frequency, or both, in response to electrical signals generated from a fluid flow sensor (5) located in the flow line.

Patent GB-2071999-A (GB)
Title: Brussels sprout stripper
IPC: A23N15/01
Filed: 1981-03-20
Abstract: Apparatus for stripping attached parts, such as Brussels sprouts, from a stalk includes a rotary stripper head (2) with pivoted lever arms (6) carrying respective knives (7). When the stripper head (2) is rotated, the knives (7) are moved towards the stalk, against the action of biassing springs, by the effect of centrifugal forces on movable masses (8) associated with the lever arms (6). The knives (7) project from the leading ends of the lever arms (6) so that the cutting edges of the knives (7) will be closer to the stalk than the trailing edges as the lever arms (6) move towards the stalk, thereby permitting cleaner stripping than is possible with known apparatus in which the knives are carried at the trailing ends of the arms. <IMAGE>

Patent GB-2078197-A (GB)
Title: Load limiting device
IPC: B66C23/90
Filed: 1981-05-14
Abstract: A load-limiting device is provided for hydraulically operated cranes of the kind comprising a lifting arm 3, a rocker arm 4 and, in some cases, an extension arm 5, which are operated by respective hydraulic cylinders 6, 7, 8. A pressure switch 13 senses the pressure in the hydraulic cylinder 6 of the lifting arm 3 and is disconnected when this pressure reaches a predetermined maximum value. The pressure of this cylinder 6 is a function of the moment of load. A means 19 sensing the angle of the rocker arm 4 relative to the horizontal plane cooperates with the pressure-sensing switch 13 and affects a number of blocking valves 15 to 18 so as to assume positions in which they prevent moment-increasing movements of the crane 1. The moment-increasing movements that art thus prevented are lowering of the lifting arm 3, extension of the extension arm 5 and, in the case that the rocker arm 4 is directed upwards, lowering movements of this arm or, in the case that the rocker arm 4 is directed downwards, raising movements of said arm. As alternatives, the blocking valves 15 to 18 may be replaced by inductive switches and an electric system controlling a shunt valve. <IMAGE>
