Abstract: 629,572. Automatic exchange systems. WESTERN ELECTRIC CO., Inc. Aug.. 7, 1947, No. 21758. Convention date, Sept. 24, 1938. Drawings to Specification. [Class 40 (iv)] All the digits of a subscriber's number are transmitted simultaneously in a single pulse consisting of a combination of voice frequency currents. As described, 16 frequencies are allocated for the transmission of a 4-digit number, 4 frequencies being allocated to each digital position, the individual digits of which are characterized by different combinations of two out of the four frequencies. The invention is described with reference to the transmission of wanted subscriber's numbers between two exchangers of revertive control type, the V.F. pulse being transmitted from a register at the originating exchange to set 4 sets of 4 storage relays in a register at the receiving exchange, each set being used in turn to determine the point of entry into a relay chain which is then run down by revertive impulses during the setting of the selector switches in the usual manner. Specification 176,889, [Class 40 (iv)], is referred to.

Abstract: 1,140,948. Evaporators; crystallization of sugar. SOC. FIVES LILLE-CAIL. 17 May, 1966 [21 May, 1965], No. 21828/66. Heading BIB. During the concentration and crystallization of solutions, e.g. of sugar, flowing through an evaporator divided by partitions 12 having apertures 16 into a series of cells, encrustation of the lateral walls 22 and the partitions 12 is prevented by directing streams of undersaturated solution through nozzles in pipes 20 into the cells so that the solution flows in film-form, over the surfaces of the lateral walls and partitions. The evaporator is provided with longitudinal heating plates 14. The solution to be crystallized is introduced at A into the first cell of the evaporator, where the solution is concentrated to saturation. The solution is then conveyed by pump 17 to the second cell, seed crystals being added at 21. Crystallization commences in the second cell; and screw conveyor 18 effects the movement of the suspension of crystals through the remaining cells via apertures 16. The final product is removed from the last cell at B. The irrigation pipes may be operated intermittently.

Abstract: 464,317. Utilizing tidal energy; raising water. PROCTOR, C. F. Aug. 13, 1936, No. 22313. [Class 69 (i)] [Also in Group XXVIII] Air, alternately compressed and rarefied in a tidal chamber by the rising and falling tides, is caused to force water upwardly through a series of superposed tanks by simultaneous or alternate exertion of pressure and suction upon it.

Title: Improvements in controlling devices for hydraulic shock absorbers
IPC: F16F9/34
Filed: 1932-08-10
Abstract: 400,382. Vehicle &c. shock-absorbers. SALENIUS, C. G. T., 44, Birger Jarlsgatan, Stockholm. Aug. 10, 1932, No. 22413. Convention date, Sept. 14, 1931. [Class 108 (iii).] Relates to hydraulic shock-absorbers for use on motor vehicles &c. and of the kind in which an operated member such as a piston or vane moves within a pressure chamber filled with liquid and forces the liquid through an escape opening formed of two relatively movable parts, at least one of which is actuated partly in one direction by a spring and partly in the opposite direction by the liquid pressure in the chamber, the latter movement being against the effort of the spring and increasing the resistance at the escape orifice. According to the invention, the movable valve part is connected to a piston so influenced by the pressure in the chamber that a counter-balancing pressure is obtained which assists the efforts of the spring on the movable part, and thereby allows a lighter spring to be employed. The escape opening may be varied by throttling the same or by increasing the length thereof or by both methods in conjunction. In the construction shown in Fig. 1 the valve 5 actuated by the pressure of the liquid in the chamber P is adapted to throttle the escape opening 2 in the wall 1 against the action of the spring 4, and the counter-balancing pressure is derived from an independent piston 17 connected to the valve 5 by a double-armed pivoted lever 15. In another construction, Fig. 2, the valve 34 is made to act as a differential piston by connecting a space 38 at the rear of the valve spindle 37 to the area 36 of reduced pressure by means of a bore 39 in the valve. Other modifications are described in which the valve is formed integral with a cushioned piston, and in which a bore through the valve connects the pressure side of the valve to a chamber in which the pressure so transmitted reacts on a piston integral with the valve. Fig. 5 shows another arrangement similar to that last described, in which the length of a helical passage 72 formed on the valve 71 is increased with increasing pressure in the chamber P, while in a still further construction, Fig. 7, the valve or piston 94 with bore 93 is adapted to regulate the size of a wedge-shaped opening 91 in the cylinder wall 92, the spring 95 being disposed in the counter-pressure chamber.

Abstract: 836,836. Starting gas turbine engines. DE HAVILLAND ENGINE CO. Ltd. Jan. 17, 1958 [July 17, 1957], No. 22692/57. Class 110(3). In a method of starting a gas turbine engine by means of an auxiliary turbine, the auxiliary turbine is actuated by working fluid derived from water and decomposed hydrogen peroxide in such proportions as to maintain the resultant working fluid within a medium temperature range, i.e. within the range between 225‹ C. and 350‹ C. The starter turbine 17 is mounted within a hollow centre body 11 at the inlet end of the engine compressor, the starter turbine shaft 18 driving through epicyclic reduction gearing 19 and a free-wheel coupling 20. The coupling 20 comprises an axially movable sleeve 22 having dog teeth 23 which may engage corresponding teeth on the main compressor rotor shaft 21, the sleeve 22 having an internal quick-pitch screw thread which co-operates with a corresponding thread formed on a spigot driven by the gearing 19. When the starter turbine rotates the inertia of the sleeve 22 causes it to move axially until the dogs 23 engage. Working fluid is supplied to the starter turbine from a catalytic decomposition chamber 32, the chamber being fed with a mixture of hydrogen peroxide and water from a reservoir 30 which is pressurized by air from a cylinder 31. The decomposition products pass through duct 33, an automatic shut-off valve 34, 35 and duct 25 to the starter turbine. The exhaust fluid discharging from the turbine passes through ducts 26 into the engine air intake duct 12. The preferred proportions for the mixture are 73% hydrogen peroxide to 27% water by weight, the water preferably being distilled to remove impurities. Specification 836,835 is referred to.
