Abstract: 819,398. Rocket projectors. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. June 18, 1957 [July 4, 1956], No. 19149/57. Class 92 Rockets 7, Fig. 1, in a magazine 1 of a rocket projector are automatically fed into a loading chamber 4 adjoining the firing tube by means of a uniformly rotating feeder drum 3, the drum having closure faces 15 which in co-operation with a spring-loaded closure flap 45c, Fig. 2, operated by the rockets entering the loading chamber 4, close the loading chamber 4 during firing as shown in Fig. 9, the rockets being fed through the magazine by a carrier 6 arranged behind the last rocket and connected by tension belts 11 which wind themselves upon drums 35 in driving connection with the feeder drum 3. The rockets 7 are pushed by the carrier 6 out of the magazine into a duct 67, Figs. 1, 8 where the foremost rocket is forced by a spring-loaded bolt 73 and by a lever 59 into a recess 17 of the feeder drum 3. The rocket is accelerated by the drum and is guided through the duct 67 at a speed exceeding that of the subsequent rockets, which are left behind, thus permitting the drum 3 to turn into the gap thus formed and convey the rocket completely into the loading chamber 4, the flap 45c being first pushed aside and then swinging back into the duct 67 with the closure face 47 hugging the rocket. Thus the loading chamber is closed by the closure faces 15 and 47 of the drum and flap respectively. The re-loading of the magazine is effected by pushing the rockets into the recesses 17 of the feeder drum 3 through an aperture 74, Fig. 3 (not shown) in the drum casing and by turning the feeder drum by the aid of a hand-crank. A rib 53, Fig. 2, on the flap 45c engages in an annular groove on each rocket to restrain it from longitudinal movement and the same purpose is served by ribs 58 and 61 of spring levers 56 and 59 as well as by U-section rails 62, Fig. 1, in the magazine.

Title: Hydraulic Actuator
IPC: G21C1/30
Filed: 1967-04-27
Abstract: 1,173,025. Hydraulically actuated friction clutches and brakes; change speed control. FORD MOTOR CO. Ltd. 27 April, 1967 [19 May, 1966], No. 19354/67. Headings F2C, F2D, F2E and F2F. A fluid pressure, piston-and-cylinder, actuator effecting friction clutch or brake engagement in a vehicle automatic change speed gear comprises a one-way valve so arranged in the piston head that during the final stage of said engagement a pocket of air is tapped in the cylinder to cushion the force build-up on the piston. As shown, a Reverse and two-way Low multi-disc friction brake 196, 198 is engaged by a presser plate piston 190 slidable in a cylinder 188 and acted on by fluid pressure against springs 192. The piston and cylinder are stepped and sealed to provide a main working chamber 240 and an auxiliary working chamber 242. A restricting orifice 246 and a one-way ball valve 264 in the piston are arranged between the chambers 240, 242, and a further one-way ball valve 252 (Fig. 3) in the piston is arranged between the chamber 240 and the spring chamber. In operation, when fluid pressure from a " front " pump (52) is supplied, via a passage 256, to the auxiliary working chamber 242, the piston intially moves rapidly leftwardly due to pressure in this chamber for slack-taking-up friction disc engagement. Since during this rapid piston movement the capacity of the orifice 246 is insufficient to permit filling of the main working chamber 240 the ball valve 252 opens and admits air into the latter chamber. Eventually as pressure admitted through the orifice 246 builds up in the chamber 240 the ball valve 252 closes and traps air in the latter chamber to cushion force build-up during the final engagement stage. On release of pressure from the passage 256, the springs 192 return the piston rightwardly, the one-way valve 264 opening to by-pass the orifice 246. The hydrodynamic-epicyclic change speed gear described is otherwise substantially that of Specification 1,085,269.

Title: Improvements in the treatment of raw cement materials
IPC: B03B9/00
Filed: 1938-06-30
Abstract: 516,601. Cements. EVERY, C. E. (Smidth & Co. Aktieselskab, F. L.). June 30, 1938, No. 19451. Drawings to Specification. [Class 22] A process for correcting, for cement manufacture, the composition of limestones, marls, chalks and other ores which when ground yield a product the finer particles of which contain a given mineral or minerals in a different proportion from the coarser particles, by reducing the proportion of a mineral or minerals in excess, consists in grinding the ore to such a degree of fineness that slimes are produced and then separating it into two fractions, a fine and a coarse, e.g. by means of a centrifugal separator. Suitable separators are described in Specifications 479,872 and 479,891, [both in Group II]. The fraction containing the unwanted mineral or minerals, which fraction may be either the finer or the coarser, is rejected or used for other purposes and the other fraction is embodied in or forms the final product. Instead of treating the whole ore as described it may be separated into two portions, usually after the grinding, and one of these may be divided into two fractions, the one containing the excess minerals being rejected and the other combined with the untreated portion of the ore. In an example, a soft marl consisting mainly of 'soft clay slate and hard limestone and containing about 50 per cent. of CaCO 3, was ground to such a particle size that 67 per cent. was below 2 microns. A suspension containing 80-85 per cent. of water was separated into two fractions by a centrifugal separator at a speed of about 2,000 revolutions per minute. The fine fraction had a CaC03 content of about 33 per cent. and the coarse fraction a CaCO3 content of 71 per cent. The coarse fraction could be used in the manufacture of cement and if the lime content were too low it could be further enriched e.g. by means of froth flotation.

Title: Process for the preparation of tetraethylenepentamine
Filed: 1953-07-14
Abstract: Tetra-ethylene pentamine is prepared by reacting 2,21-dichloro diethylamine, or a salt thereof, with at least the stoichiometric quantity of ethylene diamine, following which the greater part of any excess ethylene diamine is distilled off from the reaction mixture, the residue is treated with alkali hydroxide to liberate the tetra-ethylene pentamine from its salt and subsequently recovering the pentamine by vacuum distillation. Large excesses of ethylene diamine, e.g. 10-18 times the theoretical two molar proportions, are employed to obtain high yields of the pentamine.  The diamine may be used in the anhydrous form or in solution in water or other solvent, e.g. ethanol or propanol.  The dichloro-diethylamine is preferably used in the form of the hydrogen chloride salt which may be added to the diamine in aqueous or alcoholic solution or portionwise in the solid state.  The reaction is preferably effected at the boiling temperature of the reaction mixture.  An example is given.

Title: Improvements in and relating to flushing cisterns and the like of the injector started syphonic discharge type
IPC: E03D1/08
Filed: 1933-07-12
Abstract: 421,833. Siphon - discharge waterwaste preventers. BOYCE, R. O., 3, Muswell Hill, Glen Iris, LAWRENCE, K. P. H., 392, Richardson Street, Middle Park, POWELL, R. A., Hilary Grove, Malvern, and NEWTON, R. W., Glen Iris Road, Glen Iris, all in Victoria, Australia. July 12, 1933, No. 19737. Convention date, July 12, 1932. [Class 26] [See also Group XXIX] In an injector-started, siphon-discharge waterwaste-preventer, the injector and refill valves are structurally combined in one unit, which comprises a supply inlet 3, Figs. 1, 2, refill and injection outlets 27, 26, Fig. 2, and a hollow piston-valve 7 between the inlet and outlets and disposed in a chamber 6 which communicates with the inlet by a byepass 17 ; the valve 7 is moved from its seating when an auxiliary valve 21 within it is opened to permit passage of water from the chamber, its subsequent return being retarded prior to the actual closing by the covering of the byepass outlet by the piston and by the provision of a depending skirt 12 upon the piston. A stem 24 depending from the starting - valve which may be of the mushroom type normally depends between the faces of manuallyoperable valve 29 which normally closes the injector outlet 26 ; when moved to close the filling outlet 27 and thus open the injector, the valve 29 tilts the valve 21 and allows water to escape from the chamber via apertures 15, whereupon the valve 7 is lifted by the pressure of the supply and water passes to the injector to start the siphon. As the level falls in the cistern, an arm 48 of a bell-crank, the other arm 46 of which constitutes the float-arm, presses upon a spring-pressed lever 49 which thus maintains tilted the stem 24 despite the return of the valve 29 so that water passes to the inlet 37 until the rise of the float permits the valve 21 to return and the valve 7 to fall. In another form, Fig. 4, the float-trip mechanism is dispensed with and the mushroom-valve is manually operated by the push 51, the floatvalve being of ordinary construction and disposed in a chamber associated with the valve chamber.
