[Classes 69 (ii) and 135.] Fluid-operated apparatus for actuating the moving parts of machine tools, the speed-change mechanisms of motor vehicles or machine tools, or operating and controlling any fluid-actuated machinery, of the--kind comprising a piston moved by temporarily stopping free flow of pressure fluid by movement of a control valve, is provided with a valve by which the fluid can be diverted, so that the control valve may be moved without causing an immediate actuation of the piston. Apparatus for controlling the speed-changing mechanism of a drilling machine comprises two cylinders c, Fig. 1, a common control valve h<1>, and a valve o, which is operated to byepass the cylinders when the machine is working, by a lever p connected to the clutch or belt fork. Another form for operating the speed-changing mechanism and clutch of, e.g. a milling machine, comprises single-acting cylinders c, Fig. 2, for actuating the speedchanging-mechanism through a lever q and rod s, and a cylinder c<1> for actuating the clutch or belt fork. The control mechanism consists of valves 1, 2, 3, corresponding to three speed changes, and starting and stopping valves ; the valves 1, 2, 3 may be operated while the machine is at rest or in motion, no change occurring until the starting or stopping valve is actuated. The pistons for actuating the lever q may be telescopic, the outer part serving to actuate a plate 12, Fig. 8, in order to release a catch 8 on the lever from a notch in a quadrant 10, a spring r then causing the inner part to move the lever. The control valves may be selectively actuated by a plate 15, Fig. 10, having recesses 16 ; the plate is set by a rotary motion and then is given axial movement to actuate the desired valves by a piston 18.

Abstract: 1,125,663. Laminates. SOC. RHODIACETA. 21 July, 1966 [27 Aug., 1965], No. 32774/66. Heading B5N. A floor covering material, of total thickness between 1À5 and 5 mm. consists of a film 1 of synthetic polymer of thickness 0À5 to 3 mm. and a base layer 2 consisting of a web of oriented essentially continuous organic filaments arranged at random in a non-parallel manner across the web; the density of the web being less than 0À2 kg./dm.<SP>3</SP> and the film comprising 70 to 85% by weight of the total weight of the material. The film 1 may be produced from a plastisol, e.g. one based on P.V.C., or from resins based on polycondensates, e.g. polyamides or polyesters, or from polyolefines, and may include plasticizers, antioxidants, chalk, and colouring agents. The base layer 2 may be a web of " spunbonded " filaments of polyethylene terephthalate, isotactic polypropylene, polyamide, polyvinyl chloride, pdlyvinylidene chloride, cellulose acetate, or polyacrylonitrile, and may be needle punched. The layer 2 may consist of two or three " spunbonded " webs joined by needle punching. In one described method of making the floor covering polyethylene terephthalate is extruded from a heated spinneret, and the extruded filaments pass to a drawing tube before being deposited by an oscillating deflector on to an endless moving belt. The web so formed is needle punched. A plastisol which comprises P.V.C. and which has been spread by a doctor blade on to a siliconized paper is applied to the " spunbonded " web by pressure and controlled spacing. After passing the assembly through an oven to gell the polymer the siliconized paper is removed. The resultant product is resilient, and wear, abrasion, rot water, moisture and deformation resistant.

Title: Improvements in apparatus for automatic telephone systems
IPC: H04M1/274
Filed: 1945-12-05
Abstract: 603,275. Automatic exchange systems. MACKENZIE, T. W. Dec. 5, 1945, No. 32923. [Class 40 (iv)] In a key-operated 'impulse sender having a key for each complete number, the keys are arranged in two rows 19, 20, Fig. 4, and corresponding to each row there is provided a common rod 30, 31, for tensioning the driving spring 44, 45, Fig. 3, for the impulsing cam 70, Fig. 4, and a common square shaft 51, 52 for splitting up the generated impulses into digits. When a key is depressed, a rack 80 on its stem rotates the rod 30, 31 and a ratchet 37, Fig. 5, thereon turns under its pawl 38. As the key rises, the cam 70, Fig. 4, is driven by the tensioned spring through gearing 35, 74, 73, 72, Fig. 5, under the control of a governor 78 and generates impulses at contacts 69, 71, Fig. 4. For the control of the shaft 51, 52, the stem of the key has a series of surfaces 82 separated by notches 81. During the downward movement, the shaft 51, for example, is turned slightly clockwise without effect. During the upward movement, however, each of the surfaces 82 turns the shaft 51 anti-clockwise. so that a spring-biassed toothed lever 58 draws the rod 62 outwards to close contacts 66, 67, which render effective the impulses generated at contacts 69, 71, while each notch 81 allows the rod 62 to return to mark the end of a digit. When any key in one row is depressed, all keys in the other row are locked in the raised position by means of interlocking cams 84, 85, Fig. 3 (see also Fig. 9, not shown), secured to shafts 40, 41 and so shaped that if one is rotated the other is locked against rotation. In addition, the keys on each side of the depressed key and in the same row are also locked by a spring-loaded ball arrangement (see Fig. 1, not shown) in which the stem of the depressed key displaces a ball on each side so as to enter a recess in the adjacent key and hold it in the unoperated position.

Title: Improvements relating to organic polymer filaments and film
IPC: D02J1/22
Filed: 1966-07-22
Abstract: 1,143,474. Artificial films and filaments. CELANESE CORP. 22 July, 1966 [26 July, 1965; 1 Oct., 1965], No. 33027/66. Heading B5B. An organic polymer exhibiting crystallinity and of lower density than normally obtained by the extrusion of a liquid consisting of or containing the polymer and stretching the solidified extrudate, is obtained by extruding such a liquid and subjecting the extrudate during or after solidification to treatment ensuring the polymer crystallinity of the solidified extrudate is at least 50%, and then stretching and heating it, while holding it against shrinkage, for a sufficient time to reduce or eliminate its tendency to contract on release from tension. Specified polymers are nylon, polyesters, polyolefins, polacetals and polyoxymethylene. The increase in crystallinity is achieved by conventional methods known for the particular type of polymer, e.g. by the action of heat and/or swelling agents. The polymer may be oriented in the as-spun condition by choice of a suitable spinneret; some polymers may also be melt extruded in such a manner that their crystallinity is already 50% or more. The process renders the products microporous and/or voided (pore size about 3000Š.) Filaments having micropores less than 3000Š are claimed per se for the following polymers when the density of the filament is the given percentage of that of non-porous, otherwise similar filaments; polyhexamethylene adipamide* (85-90%), polycaprolactam* (85- 90%), polyethylene terephthalate # (79-85%), isotactic polypropylene # (55-65%) and polyacetal polymers # (55-65%). These polymers are given their high crystallinity; *by treatment in aqueous phenol; #by heating; # by extrusion. The acetal polymer is derived from trioxane and ethylene oxide, stabilized with cyanoguanidine and 2,2<SP>1</SP>-methylene-bis- (4-methyl-6-t-butyl-phenol)

Title: Apparatus for the manufacture of wire netting
IPC: B21F27/06
Filed: 1928-11-12
Abstract: 321,068. Pearson, A. Nov. 12, 1928. Making netting. - In machines for making wire netting by twisting the wires together while they are held at the centre of pinions or between semi-pinions the untwisted sides of the meshes are formed by drawing the wire against raised triangular faces of the same length on a roller. The wires are fed through the machine by an intermittently-operated mesh roller provided with a series of spaced bars 15 having staggered triangular projections 16, the end projections being grooved to engage selvedge wires. The wires are drawn through a pair of guides 36 which are slidable in opposite directions across the mesh to bring together different pairs of wires successively. The pairs of wires are engaged by pairs of half-pinions 28 carried by shrouds 27 which are moved apart so as to free the wires and then across the mesh in the same direction so as to position them opposite the different pairs of wires successively and then moved together. One set of half-pinions has a central projection and the other a corresponding recess, which cooperate to form a double twist when the pinions are rotated. The separating motion is effected' by wedge bars 31 operated by links from a rock shaft and the closing motion by springs 29, 30. The shrouds are moved across the mesh by a cam operated rod 35 and slotted member 34. Oiio of the shrouds contains a rack 26 for rotating the pinions. the rack being operated by a reciprocating rod 21 pivoted to a slidable bar 22 which is connected to an arm 23 capable of sliding in a fork 25 attached to the rack so as to allow the rack to move laterally during the operating and closing motion. The divided pinions may be replaced by pinions with openended slots and projections, in which case a single shroud only is used, slotted to accommodate the pairs of wires.

Title: A process for leaching out protein-containing substances such as fish waste and the like
IPC: A23J1/04
Filed: 1927-12-07
Abstract: 282,068. Chemische Fabrik Schlutup Dr. M. Stern. Dec. 7, 1926, [Convention date]. Albumens.-In the leaching of fish waste and the like containing salt for the removal of the salt, the extraction water is treated so as to render it less capable of dissolving proteins before or during the extraction; or, alternatively, after the extraction, in which case the protein dissolved is precipitated and returned to the leached fish. Substances which precipitate protein, such as metal salts, may be added to the water, or colloids such as glue or protein which diminish the amount of protein dissolved from the fish. If in spite, of the precautions taken protein is still dissolved in considerable quantity, it is precipitated in a suitable manner and returned to the leached fish. Salts of iron, aluminium, zinc or chromium may be used as precipitants. If the same liquor is employed to leach several charges of waste, less protein is dissolved in the later treatments as only a limited quantity will dissolve in the liquor. In an example, salt-containing fish-waste is leached with water, and the liquor is then treated with the requisite quantity of a salt of iron, aluminium, zinc, &c., and the precipitate is filtered, dried, and returned to the leached fish. Some fat may be contained in the precipitate. This may be removed in known manner.

Abstract: 812,869. Portable drilling-machines. CONSTRUCTIONS ELECTRO-MECHANIQUES DE SAINT-ETIENNE, ANCIENNE USINE WAGEOR. Oct. 28,1957 [Oct. 31,1956], No. 33507/57. Class 83 (3). A portable electric drilling-machine comprises a feed screw 26 and a nut 27, one of which is rotated by a main motor M1 rotating the drill 20 and the other of which is rotated by an auxiliary variable-speed motor M2 with two speed ranges. The speed ranges are obtained by providing the motor M2 with two stator windings having respectively four and six poles. Three windings may, however, be provided. The motor M2 is mounted at the rear of twin guides 10 which support the main motor M1, a fixed drill guide 21 and a movable guide 22. The motor M2 has a slip (15 per cent) greater than than that of the motor M1 (5 per cent) and is a squirrel-cage asynchronous motor. Associated with the machine is a control panel 32 having push buttons A-F and a control box 33 containing relays and contactors. The pushbuttons initiate stopping and starting of the motor M1 (A, B), reduction of drill-feed-speed, (C), stopping of drill feed, (D), reversal of drillfeed (E), and increase of drill-feed (F). Switches G, H on the guide members 10 limit forward and rearward travel. In operation, the button B is pressed to start the motor M1, the button C is pressed to start the motor M2 at a low speed and button F to increase the feed speed. The drill is then fed at a fast rate until the load on the motor M1 reaches a given value and an overload relay is actuated to cause the slow feed to again operate. The drill may then be reversed by pressure on the button E, causing the motor M2 to rotate at its high speed in the drill-withdrawing direction. The buttons D, A are then pressed to stop the motors M2, Ml.
