Filed: 1962-06-12
Abstract: 974, 376. Fluid-pressure servomotor systems. LITSCHANA Inc. June 12, 1962, No. 22437/62. Heading G3P. The supply of water to a flushing tank 1 is regulated by a main diaphragm-valve 20 under the control of a float-actuated pilot-valve 31. With the tank filled to the level A the parts are in the position shown with both valves seated. Upon emptying the tank a main float 10 falls and, via a cam 46, tilts and lowers the pilot valve 31 to permit the water in a chamber 43 behind the main valve 20 to flow into the tank by an annular space between the walls of chamber 43 and the inner float wall 15; build-up of back pressure is prevented by port 50 in the cam 46 which opens to a chamber in the float cover 52 with a vent 51. Release of pressure in chamber 43 enables the pressure in the inlet 18 to unseat the main closure 20 and urge it against a spider backing member 24 whereupon the inlet water passes through a number of seat ports 26 into the tank after impinging upon a shoulder 57 which reduces the filling noise. As the water level rises the main float is lifted as is an auxiliary float 34 in chamber 43 which thereby seats the pilot valve 31; the chamber 43 is open to the inlet 18 through a member 40 with a passage 41 and a lateral slot 42 so when the chamber pressure is the same as that of the inlet the main valve 20 closes. A surge damper 35 in the chamber acts as a stop for the auxiliary float 34. The main valve seat 19 has inner and outer annular flanges, the latter being contacted first to avoid surging and water hammer. Upstream of the inlet 18 is a filter 58 and a variable throttle 62 comprising an outer slotted member and an adjustable, inner cup-shaped member the position of which determines the flow through the slotted member.

Title: A repetition impulse operator for locks or other purposes
IPC: E05B37/16
Filed: 1948-08-27
Abstract: 656,858. Permutation locks. HOLAN. A. Aug. 27, 1948, No. 22637. [Class 44] Operating means applicable to a permutation lock of the type comprising a number of elements some or all of which have to be actuated, comprises a smaller number of operational parts, such as pushbuttons, keys, or imaginary "fields" on a single element, adapted to be operated by repeated impulses given to one, or jointly to two or more of the operational parts each impulse causing the lock to shift one step relatively to the operating means and simultaneously causing the actuation of one of more elements of the lock, so that after a predetermined number of impulses given to the operational 'parts in the correct order and combination, the elements of the lock have been actuated to release the mechanism. In the form shown in Fig. 1, the lock body b, having pins c, certain of which have to be depressed, is mounted to rotate in a frame a, in the front part of which is mounted a shield e which is normally held against a rim of the frame a by a spring j housed in a sleeve i, externally threaded to engage an internal thread in a ring l. The sleeve is held against rotation by a pin and slot. and the ring l is free to rotate and framed on its periphery with ratchet teeth which engage a pawl d on the lock body. Depression of the shield by finger pressure at any point around its edge causes inward movement of the sleeve, rotation of the ring l and consequent rotation of the lock body through the angle subtended by one tooth of the ratchet. The shield is provided with two, three or four projections f, which when the shield is depressed at the point where the projections are located, actuate the pin or pins c of the lock which are then opposite the projections. In this way, by depressing the shield at various points successively, according to the prearranged coding of the lock, the pins thereof are correctly actuated. In an alternative form, shown in Fig. 2, two, three or four push buttons are used instead of a plain tiltable shield, each push-button having a flat spring f, one part of which engages angularly disposed teeth d on the lock body, while the other part g engages one or other of the pins c of the lock according to the position of the latter.

Abstract: 1,201,837. Phosphoric acid. MIZUSAWA KAGAKU KOGYO K.K. 14 May, 1968 [17 May, 1967], No. 22820/68. Heading C1A. Phosphoric acid and gypsum are produced from calcium phosphate or phosphate rock by mixing with sulphuric acid and at least one alkali metal salt and/or amorphous silica (which term includes some silicates) in an amount which is at most 30% by weight of the dry calcium phosphate or phosphate rock and which satisfies the equation where [M 2 O] is the weight per cent of alkali metal present calculated as oxide, [SiO 2 ] is the weight per cent of amorphous silica (including that as silicate) present, and [CaF 2 ] is the weight per cent of fluorine present calculated as calcium fluoride, all weight per cents being based on the weight of the dry calcium phosphate or phosphate rock; heating the resultant mixture at 100‹ to 300‹ C. and, if necessary, forming it mechanically before, during or after heating to form solid non-disintegrable small masses from which the phosphoric acid is extracted to leave gypsum. The alkali metal salt and/or silica may be added to the phosphate, before it is crushed, before the sulphuric acid is added, or as the sulphuric acid is added. The alkali metal salts named are the halides, sulphates, nitrates, carbonates, phosphates, hydroxides, oxides, sulphides and silicates of lithium, sodium, and potassium, sodium acetate, sodium citrate, and potassium oxalate. Amorphous "silicas" named are silica hydrogel and xerogel, alumina/silica mixture, calcium oxide/silica mixture, calcium silicate, magnesia/silica mixture, magnesium silicate and alkali metal silicate. The recommended amount of sulphuric acid is 0.8 to 1À2 the amount that is equivalent to all the metals present in the reaction mixture. The preferred size of the small masses is to 50 mm. and the phosphoric acid may be extracted by any known method, but it is preferred to extract it with water, or aqueous phosphoric acid which has been formed by extraction with water of pellets that had already been extracted with phosphoric acid to produce more concentrated acid.
