Title: Motion transmitting mechanism
IPC: F16H27/00
Filed: 1960-05-16
Abstract: 883,647. Gearing. PATRIGNANI, T. May 16, 1960 [May 28, 1959], No. 17139/60. Class 80 (1). [Also in Group XXV] Mechanism for transmitting motion from a rotatably mounted driving cam 5 to a displaceable driven member 1 comprises a ball 7 located in a guideway 2 which extends around the circumference of the cam 5 and also in the direction of displacement of the driven member 1. The driven member 1 is spring-pressed in the direction of the cam 5 and moves in that direction when the ball 7 enters a recess 8 in the cam 5 and is carried around the curved portion of the guideway 2 in a clockwise direction. On reversal of the direction of rotation of the cam 5, the ball 7 acts on the member 1 to return it to its original position. In a modification, shown in Fig. 3, a plurality of balls 7 is located in a guideway having straight portions 2a, 2b connected by a curved portion 2c, a spring-pressed plunger 1a being disposed at the end of the portion 2b, and the cam has two recesses 8, 8a. Thus, the driven member 1 is displaced a distance equivalent to twice the diameter of the balls 7 for every revolution of the cam 5. As shown in Fig. 4, the portion 2a of the guideway is arranged vertically and the balls 7 are maintained in contact with the cam 5 by gravity. In the modification shown in Figs. 5 and 6, the driven member comprises a pivoted arm 13 adapted to be moved incrementally by rollers 17 which engage recesses 18 in a driving cam 15. Fig. 10 shows a similar construction having a driven member 26 which is adapted to move laterally. Fig. 7 shows a modification in which a member 20 is adapted to be moved laterally by balls 17 which are transferred from one side to the other of a driving cam 15. In a further modification, a driven member 24, Fig. 9, is adapted to be rotated incrementally by rollers 17 which are moved intermittently by a driving cam 15. The invention is applied to a door-lock, shown in Fig. 11, in which a bolt 102 is advanced or retracted by rollers 105 which, on rotation of a cam 107, are transferred from one side of the cam to the other. The bolt 102 is integral with parallel spaced shanks 103, 103a which slide upon a raised portion of the casing. In another modification, a bolt 201, Fig. 15, has a recess 205 which is engaged by an arm 204 of a lever 202 having an arcuate surface 208 supporting balls or rollers 206. Rotation of a cam member 207 transfers balls or rollers from one side of the cam to the other and thereby effects pivotal movement of the lever 202 and consequential movement of the bolt 201.

Abstract: A cyclic process for the production of potassium nitrate and soda, with ammonium chloride as a bye-product, comprises the following steps :--(1) Gypsum is reacted with the mother liquor of an ammonia-soda process containing ammonium carbonate and bicarbonate to form a precipitate of calcium carbonate and a solution of ammonium sulphate.  After separation of the calcium carbonate the liquor is treated with sylvinite and ammonia to form a precipitate of glaserite (3K2SO4, Na2SO4) and potassium chloride, which, after separation, is treated with water to form potassium sulphate, together with a solution of sodium chloride which is returned to the process.  (2) The glaserite-potassium chloride mother liquor, containing sodium and ammonium chlorides, is cooled to separate part of its ammonium chloride and is then subjected to the Solvay process to form soda, the mother liquor of which is used in step (1).  (3) The calcium carbonate and potassium sulphate from step (1) are reacted with nitric acid to form gypsum, which is separated and used in step (1), and a solution of potassium nitrate which is evaporated or cooled to yield the solid, the resulting mother liquor being utilized to dissolve further quantities of the potassium sulphate obtained from glaserite in step (1).  The ammonium chloride obtained in step (2) may be used as a source of the ammonia used in step (1).

Abstract: 677,511. Making metal wool by planing. FIELD, C. July 2, 1947 [Sept. 18, 1946], No. 17392/47. Classes 83 (iii) and 83 (iv). Winding and reeling.-Apparatus for making metal wool &c. from coiled strip stock comprises a rotor 24 on which the coiled strip stock S is supported edgewise and cutting tools K for shaving the exposed edges of the stock, the tools being carried on a heavy spider member 44 slidable on a shaft 22 relatively to the rotor. The latter is driven from a motor 28, Fig. 14, through toothed gearing and is provided with a rim 42 to which the coil S is clamped. A detergent compound, e.g. soap, may be disposed between adjacent loops of the coil. Each tool is held in a toolholder 54 attached to a base which is free to turn, against the action of springs 76, on a shaft 58 held in the spider. The machined fibres are gathered together into ribbons W, Fig. 1, which are led over spools 84 and then between pairs of rollers 114, Fig. 14, passing first through a funnel 116, the wool then falling into receptacles or being otherwise dealt with. A blast of air may be supplied between the cutting edge of each tool and the metal strip by nozzles 194, Fig. 3, supplied from a compressor 216, Fig. 14, through a pipe 206. When metal wool is being cut in the absence of a detergent, oil may be used which is supplied from a pump 224 through a feed-pipe 232 to an apertured tube housed in a casting 242. For venting smoke, dust, and wool fragments, a vertically-movable hood 252, Fig. 1, is provided which has a metal screen 256 secured thereto and is connected to an exhaust fan 262 by a flexible sleeve 258 and a duct 260. When a coil of strip has been shaved until only a small fraction remains, the machine is stopped, the hood 252 is lowered and the spider lifted from the shaft 22. The remaining strip is removed from the rim 42 and a fresh coil of strip laid edgewise on the rim and secured in position between clamps 364 and 370, Fig. 11. When it is desired to out metal strip without a detergent, the spider is not removed from the shaft 22 but the hood 252 is lowered and a guide-plate temporarily secured to the rotor rim. In this case, a coil of metal strip is placed on a plate 414, Fig. 18, rotatably supported in a feed-basket 408, which is raised until the top thereof is at the same level as the top of the rotor rim when the end of the strip is clamped on the rotor rim, after which the motor 28 is put into operation to wind the strip under tension on to the rotor rim. Specification 677,596 is referred to. The Specification as open to inspection under Sect. 91, comprises the subject-matter of Specification 677,596.

Title: Improvements in and relating to means for preventing settlements of foundations
IPC: E02D27/34
Filed: 1933-06-20
Abstract: 416,698. Foundations of buildings. GRUN & BILFINGER AKT.-GES., and GRUN, A., Akademiestrasse, Mannheim, Germany. June 20, 1933, No. 17541. [Class 20 (ii).] Relates to a method of compressing the stable foundation soil under building foundations and foundation reinforcements so that it will be capable of bearing the predetermined maximum load. According to the invention, the foundation soil b, Fig. 2, is compressed only, or particularly heavily, under the marginal zones of the foundation, and the foundation soil is connected to the foundation under stresses corresponding to the static conditions at the moment of connection. In the construction shown, the compression is effected by presses f disposed between the building a and blocks d, e. The blocks e are inclined somewhat so that the soil outside the structure is also compressed. After the predetermined pressure has been applied, the pressure is somewhat relieved and the building is connected to the foundation soil by a filling applied under a pressure equivalent to the stresses existing in the structure at the moment of connection. In a modification, the blocks e and the presses therefor are disposed vertically. According to another method, Fig. 4, the compression of the soil is effected in the marginal zones o by a fluid building material d<1> which is applied under pressure through pipes n and which subsequently solidifies under a pressure equivalent to the stresses in the structure. In a further construction, the foundation soil b<2>, Fig. 6, is compressed by presses f<1> bearing against a laminated inverted arch p. Ties q, tensioned by further presses f<2>, are provided to counterbalance the lateral stresses produced by the presses f<1>. The arch and the ties are connected to the structure under a pressure corresponding to the load prevailing at the time of connection, and the ties may subsequently be embedded in a concrete rib p<1> which extends downwards to the arch.

Abstract: 952,261. Gravity-separation apparatus. TECHNICON INSTRUMENTS CORPORATION. May 8, 1962 [May 17, 1961], No. 17617/62. Heading BID. A liquid to be treated is supplied to a pump tube 16, an extracting solvent is supplied to a pump tube 18 and an inert gas (e.g. air) is supplied to a pump tube 17. The pump 12 is of the type where the tubes are resiliently flexible and are compressed along their lengths against a platen 22 by a series of pressure rollers 24 which are moved by sprocket chains 26 longitudinally of the tubes. The three components thus supplied to conduit 28 are mixed by passage through a series of spherical members 50 joined by narrower parts 52 and emerge at 54 into a separating vessel 14. An outlet 36 is connected to a pump tube 20 and an outlet 38 is connected to an adjustably-clamped tube 46. If the internal diameter of tube 20 is selected so that the flow rate of the separated heavier liquid through outlet 36 is less than the flow rate of heavier liquid entering at 30, and if tube 46 is clamped, the lighter liquid plus a little of the heavier liquid overflows at 42 and only the heavier liquid passes through tube 20. If it is desired to collect the lighter liquid, clamp 48 is dispensed with and tube 46 is connected to a further pump tube 54, Fig. 2 (not shown). The internal diameter of tube 20 is now selected so that the flow rate of heavier liquid through outlet 36 is greater than the flow rate of entering heavier liquid so that heavier plus a little lighter liquid flows out at 36 and only lighter liquid flows out at 38. In this latter embodiment the clamp 48 may be re instated and the diameter of tube 20 so choser that by opening the clamp the lighter liquic will be collected and by closing it the heavier liquid will be collected. Also in Fig. 2 the mixing device 50, 52 is dispensed with. Instead [a] the conduit 28 is coiled helically in the region between pump 12 and inlet 30, and the latter connects simply with the top of vessel 14. The pump is of the type shown in Specificatior 817,070. Specification 774,711 also is referred to.
