Title: Improvements in or relating to pressure regulating devices for fluid supply systems
IPC: F15B1/027
Filed: 1940-02-26
Abstract: 539,935. Valves. AUTOMOTIVE PRODUCTS CO., Ltd.. THORNHILL, P. W., and SIMPSON. J. K. Feb. 26, 1940, No. 3556. [Class 135] The spring pressure tending to hold a relief valve closed is caused to exert a lesser force on the valve when the valve is open. As shown, a pump 13 delivers liquid through a pressure regulator having alternative paths leading respectively to an outlet pipe 17 communicating with an accumulator 18, a selector valve 20 controlling a sleeve unit 23, and a return pipe 15 leading to the pump reservoir 16, and to a second outlet pipe 25 leading into the return pipe 15. The relief valve 45 is urged to its closed position by a main spring 53, and also by an auxiliary spring 51 pressing on a piston 52 engaging the flange 43 of the valve, this piston being forced away from the valve flange by the liquid pressure when the valve is open, the liquid then passing round the valve and through ports 81 in the piston to the outlet 25. At low liquid pressures the valve is closed and the liquid flows past a conical head 46 on the valve forcing a sleeve 31 back, and so to the outlet 17.

Title: Magnetic recorder equalization system
IPC: H04N9/793
Filed: 1966-01-27
Abstract: 1,113,640. Video playback. AMPEX CORPORATION. 27 Jan., 1966 [12 March 1965], No. 3764/66. Heading G5R. In an arrangement for automatically equalizing colour television signals played back from a tape 18 by a number of rotating transducers 12-15, the sync. and burst pulses associated with the television signals are used as reference signals, relative to which the equalizer operation is adjusted. The played back signals are passed through equalizers 32-35 and thence via a head switching arrangement 38 to a demodulator 40. After demodulation the near edges of the sync. signals are detected by a sync. stripper and used to open a burst gate 60 to pass the following fixed frequency burst. These signals are passed via gates which are opened in synchronism with those in the switcher 38 and are compared with standard references in the comparators 90-96. The comparator outputs are used to control the equalizers 32-35, so that each television information signal is automatically equalized. The gates in the switcher 38 and in the units 72-78 are controlled by a generator 42 operated by a strobing arrangement associated with the rotating transducer system.

Title: Improvements in or relating to the production of crystalline magnesium hydroxide
IPC: C01F5/22
Filed: 1943-03-12
Abstract: 571,467. Magnesium hydroxide. CHESNEY, H. H. March 12, 1943, No. 4099. Convention date, March 13, 1942. Drawings to Specification. [Class 1 (iii) ] Crystalline magnesium hydroxide is obtained by introducing a solution of a magnesium salt gradually into a solid convertible base with intimate mixing, and separating the spent liquid from the resulting magnesium hydroxide, the magnesium salt solution being added at a suffioient rate to complete the reaction in a period of from 2 to 20 hours. Brine or sea water may thus be reacted with burnt dolomite or lime or a slurry thereof. In continuous operation, the base may be added at one end of a long trough, being moved forward slowly by means of a screw &c. At spaced distances from the point of introduction of the base, streams of magnesium salt solution may be added to the trough, the size of these streams increasing as the distance from the point of introduction increases. The admixture of base with the initial quantity of solution should be especially thorough and is preferably carried out in a separate vessel. Alternatively, the reactants may move in counter-current in the first stage, partially reacted solution from a later stage being slowly added to the base, which is subsequently contacted with unreacted solution passing to the first stage. The above two modifications may also be carried out in a series of troughs, the precipitate being allowed to settle out of the spent mother liquor after leaving one trough before it is passed to the next trough for treatment with a further portion of the magnesium salt solution. According to another modification, the dilute solution is continuously added to the base while the spent brine is being continuously removed. This may be effected by placing the base on a filter and is best conducted in an apparatus in which a structure covered with the filtering medium is submersed in a vessel containing the solution. U.S.A. Specifications 2,089,339, 2,124,002 and 2,224,780 are referred to.
