Patent GB-2050728-A (GB)
Title: Phase Comparators
IPC: G01R25/00
Filed: 1979-05-25
Abstract: Method of, and circuit for, measuring the value of a physical variable such as the degree of fullness of a storage tank represented by the phase shift between two signals applied to a phase comparator. The physical variable is interrogated for a relatively short period (T3-T1) in an overall longer period. The charge on a storage capacitor C1 is increased by connecting it to a source of high voltage (VH) for a period (T2-T1) and is decreased by connecting it to a source of low voltage (VL) for a period (T3-T2), the instant T2 being a variable time determined by the phase displacement between the two input signals 14 and V applied to the comparator. Thereafter the capacitor is disconnected from both sources and the mean value voltage (Vm) remaining is representative of the value of the physical parameter being measured. Vm=VH[(T2-T1)/(T3-T1)]+VL[(T3-T2)/(T3-T1) =VL+(VH-VL)[T2-T1)/(T3-T1)]   <IMAGE>

Patent GB-2056613-A (GB)
Title: Hydropneumatic suspension struts
IPC: F16F9/40
Filed: 1979-08-21
Abstract: A suspension strut of the kind containing liquid and gas has a cylinder 1 which is closed at one end and the other end of which has a seal, and a piston rod 4 extending through the seal and carrying a damping piston 5. In order to prevent leakage of gas past the cylinder seal, the cylinder is completely filled with liquid. The piston rod 4 is hollow and contains a pressurised gas, preferably nitrogen, which is separated from the cylinder interior by a device 10. Thus, compressed gas does not normally leak to the cylinder interior, but liquid can pass to and from the piston rod interior to compensate for changes in volume. The device 10 may comprise a disc or a ball 11 of plastics material which floats on the liquid. When the strut is inoperative e.g. before charging with liquid, or is fully extended the ball closes on to its seat to prevent escape of gas from the piston rod. When liquid enters the piston rod the ball lifts off its seat and floats at the gas-liquid interface, allowing liquid to flow in and out of the piston rod as required. The ball may be a running fit in the piston rod to provide an actual separation between gas and liquid. <IMAGE>

Title: Method and apparatus for the manufacture of milk powder
Inventor: ROBIN MCILRAITH GRAY
IPC: B01D1/26
Filed: 1982-02-23
Abstract: In the manufacture of milk powder an evaporator is normally used to concentrate the milk before being dried in a spray dryer. The evaporator is more efficient in its use of steam for the removal of water from the milk so it is desired to feed the milk to the dryer in as high a state of concentration as possible. The increasing viscosity of the higher concentrate adversely affects the atomising which is necessary for spray drying. It has been found that the milk exhibits a delay of a few seconds in thickening to its full viscosity. Therefore a final finishing stage 3 is mounted so as to discharge into the spray dryer 4 through as little pipe line 5 as possible to maintain a relatively short residence time in the final stage. It is preferred for a plate evaporator 3, forming the final finishing stage, to be mounted directly on top of the spray dryer chamber 4. Refer to Figure 1. <IMAGE>
