Filed: 1945-08-23
Abstract: 597,616. Feedwater supply systems for steam boilers. TANNER, G. W. Aug. 23, 1945, No. 21660. [Class 123 (ii)] A boiler feedwater system comprises a twoway evaporator discharge valve controlled by an electro-magnetic solenoid 8 whereby when the water salinity is in excess of a pre-determined amount the solenoid 8 is energised, tripping a trigger lever normally restraining a spring loaded valve operating member, whereupon the water is discharged to waste and warning signals indicate that the boiler supply has been cut off. The energising contacts 7 for the circuit including the tripping solenoid 8 are controlled by a relay circuit incorporating a salinity cell 1 having a water inlet pipe 2 and an outlet 3 together with supply electrodes 4. A variable resistance 5 in the relay circuit serves to adjust the current for any required degree of salinity.

Abstract: 784,863. Photo-conductors. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 7, 1955 [July 27, 1954], No. 21832/54. Drawings to Specification. Class 37. [Also in Group XL (a)] Substantially uniform sensitivity and dark resistance is imparted permanently to the photo-conductive target of a discharge tube by scanning it with a defocused beam of high beam current whilst setting up a high voltage across gradient through the thickness of the target and illuminating it uniformly. The voltage across the target and the illumination may both be varied from a high to a low value several times. The material of the photo-conductive target is preferably a solid layer of antimony trisulphide superimposed on a spongy layer of the same material, but it may be zinc or cadmium sulphide. With the cathode at zero potential, 300 volts are applied to the limiter and anode electrodes, a variable 0-150 volts to the signal electrode and 15-200 foot candles illumination to the target. Alternatively the voltage of the signal electrode may be kept constant and the cathode potential varied. The impedance of the photo-conductive layer should not fall below 10 megohms.

Abstract: 531,605. Extracting oils ; fish meal. BURGER, W., and ROSE, DOWNS & THOMPSON, Ltd. July 28, 1939, No. 21914. [Class 91] In the extraction of water and oil from fish, fish offal, or the like, e.g. to obtain fish meal, the cooking or sterilizing of the raw material is effected by passing through it clean air heated by gases of combustion and the cooked material is, after pressing, dried by the combustion gases. For example, fish is fed by a conveyer 15 from an inlet 16 to a conduit 18, a cooker and sterilizer 17, a press 21, a tube 23, and a drier 12, while combustion gases from a furnace 10 flow through an air heater 11, the drier 12, a pipe 14, the conveyer 15, and pipes 24, 25 to condensers 26, a water-separator 27, a pipe 28, and the furnace 10 ; at the same time air from the heater 11 is forced by a fan 19 through a pipe 20 and the cooker 17 to the pipe 25. Oil and water pass from the press 21 by pipe 22 to centrifugal or other separators, from which any residue may be pumped into the drier 12.

Filed: 1975-05-22
Abstract: 1467935 Measuring current XEROX CORP 22 May 1975 [3 Oct 1974] 22044/75 Heading G1U [Also in Division G3] Errors that arise in the prior art method of measuring a corona discharge current between an electrode 3 and a plate 2, Fig. 3, by measuring the voltage across a resistor R 2  in series with the discharge device, the errors arising because of a capacitance C3 that appears parasitically across the discharge device 2, 3 are eliminated by arranging the device X, Fig. 4, which shows the equivalent circuit R 1 , CR 1 , CR 2 , C 1  of the device in full lines, by applying a reduced supply voltage across the bridge of insufficient amplitude to cause a discharge to occur, by balancing the bridge, and then by measuring the diagonal voltage across the bridge when the full supply voltage is applied. In the circuit shown the diagonal voltage is amplified and used retroactively to control the voltage applied across the bridge so that the discharge current remains constant. As described the plate 2 forms part of a photoreceptor in a xerographic printing apparatus and the refinements of the invention over the prior art are especially desirable because of the tendency to use supply voltages in the range 400 to 600 Hz rather than mains frequency, to eliminate the production of strobed charge patterns.
