Title: Improvements in or relating to circular knitting machines
IPC: D04B15/92
Filed: 1955-12-02
Abstract: 801,449. Knitting-machines. BOOTON, Ltd., W. E., BOOTON, H., and NEAL, H. Nov. 20, 1956 [Dec. 2, 1955], No. 34506/55. Class 74 (2). Pneumatic fabric take-down mechanism is provided in a circular seamless hose machine which draws under suction the fabric as it is produced into a conduit 23 disposed slightly eccentrically within the needle cylinder. On completion of a stocking and after it has been cast off the needles, it is drawn through the conduit 23 and a connecting pipe 22 into a receiving chamber 21 having a perforated bottom which is attached to a control valve 29. During the knitting of a stocking the control valve 29 connects the suction device to the receiving chamber so that the air flow draws the stocking downwardly into the conduit. Just prior to casting off the completed stocking a cylindrical control valve 45 in the chamber 21 is rotated to close the entrance of the pipe 22 into the chamber and thereby stop the takedown action produced by the flow of air being drawn by the suction device. This permits the stocking to be cast off and the yarn to be severed without drawing a long length of yarn from a feeder. On completion of casting off the stocking the valve 45 is returned to open the entrance to the pipe 22 and to permit the stocking to be drawn into the chamber 21. The valve 29 is thereupon reversed so that air is blown into the chamber 21 to eject the stocking out of the end of the chamber into a receptacle 37 from which it may be removed by an operative. The valves 29, 45 are controlled to operate at appropriate times from pattern drums on the machine.

Abstract: 1367632 Vices RABONE CHESTERMAN Ltd 28 Sept 1971 [21 July 1970 22 Oct 1970] 35311/70 and 50253/70 Heading B3B [Also in Divisions F2 B4 and B8] In a screw and "half-nut" mechanism, a screw 10 is mounted in a cylindrical bore 12 and is engaged by a threaded end of a cylindrical plunger 16 slidably mounted in a cylindrical bore 18 having an axis inclined relative to a plane perpendicular to the axis of the screw. The arrangement is such that when the screw is tightened, the thrust which it exerts on the half-nut produces a tendency for the latter to be crowded into engagement with the screw. The screw may have a buttress thread or a square thread. For quick release, the plunger 16 is moved axially out of engagement with the screw. In a screw cramp, quick release of a spring-pressed plunger is obtained by operating a button 42, Fig. 4. A similar arrangement is employed in a woodworkers vice. In a metal workers vice, a half-nut is held in engagment with a screw by a shaft 150 which may be rotated to a position in which a flat 152 on the shaft 150 allows the half-nut to move out of engagement with the screw.

Title: Improvements in or relating to the production of crystalline semiconductor materials
IPC: H01L21/00
Filed: 1963-09-09
Abstract: Gallium phosphide is prepared in the form of blade-shaped crystals by charging one end of an open elongated reaction chamber with metallic gallium in a quantity insufficient to dissolve any gallium phosphide formed, heating the end of the chamber containing the gallium to a temperature in the range 800-1200 DEG  C. to transform the gallium to the vapour phase and contacting the heated element with a halogen compound of phosphorus, thereby to form crystal blades of gallium phosphide in a cooler region having a temperature of 600-900 DEG  C. at the other end of the reaction chamber.  The exit regions of the reaction chamber are preferably heated to 1050 DEG  C. so as to volatilize the by-products of the reaction and assist their removal. The halogen compound of phosphorus is preferably PCl3 and is preferably introduced from a source external to the reaction chamber by passing the gas over liquid PCl3 at 0 DEG  C. at a flow-rate of 70 ml./minute.

Title: Improvements in or relating to mosaic electrodes for use, for example, in cathode ray tubes
IPC: H01J29/43
Filed: 1935-12-23
Abstract: 467,838. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 23, 1935, No. 35627. Convention date, Dec. 21, 1934. [Class 39 (i)] [Also in Groups VIII and IX] A mosaic electrode comprises a wire-mesh screen which is etched in a corrosive bath to enlarge the interstices and is coated with an electrically insulating substance. A, screen, which may consist of nickel, stainless steel, or of the material known under the Registered Trade Mark " MONEL " is rolled to embed the warp within the weft and then etched. For a stainless steel screen, the etching solution consists of 35 per cent to 40 per cent aqua regia in water at a temperature of 30‹C. and for a nickel screen, the solution consists of 60 per cent nitric acid in water at 30‹C. ; iron dust may be added to the solution. The mesh is then cleaned in an alkaline bath, silver- or nickelplated to bond the wires together, and coated with insulating material. An enamel which consists of feldspar, borax and silica and a binder, such as cobalt oxide, may be sprayed on the screen and vitrified. The interstices are filled with a paste of a finely divided metal, e.g. silver, or a reducible oxide thereof, and a binder. The ends of the metal inserts on one side of the screen are photo-sensitized, e.g. by depositing caesium thereon. The screen 34 is mounted through supports 44 within a cathode-ray tube which comprises an electron gun 18 and deflecting systems 30, 32 either of which may be electrostatically or electromagnetically operated. Electrons released from the photo-electric surface are collected by an anode 48 and secondary electrons emitted from the other side of the screen are collected by the accelerating and concentrating anode 35 which consists of a coating on the bulb. Dimensions of the screen are given in the Specification.
Patent GB-1010467-A (GB)
Title: Improvements in or relating to looms
IPC: D03C1/12
Filed: 1962-09-19
Abstract: 1,010,467. Loom dobbies. RUTI MACHINERY WORKS Ltd. Sept 19, 1962 [Sept 26, 1961], No. 35744/62 Addition to 1,004,777 Heading D1E. In a positive single-lift open-shed dobby, the jack levers 116 are actuated by eccentric straps 20, the sheaves of the eccentrics being attached to sun wheels 125 around which planetary gears 133 are oscillated by a cam 139. Each planetary gear rolls idly on its sun wheel except when a gear 142 is locked against rotation, in which case the planetary gear turns the eccentric from one dead centre to the other to operate the jack lever. The gear 142 can be locked by a pin 149 entering a notch 148 in a locking plate 146, the pin being carried by a bell crank lever 152 which is rocked by a cam 156 during every cycle to lift the pin 149 clear of the locking plate 146. Engagement of the pin in a notch 148 is governed jointly by the pattern card and the position of the jack lever by means of a floating lever 170, the lower end of which is pivoted to the jack lever on a spring 171 and can thus occupy two positions corresponding to heald up and heald down; the upper end is linked to the pattern mechanism and can occupy two positions produced by the presence and absence of a hole in the card. The middle of the floating lever is linked to a block 166 sliding in a slot 158 in the bellcrank lever and also slidable in a vertical slot 167 in a fixed bracket. When the cam 156 rocks the bellcrank lever to lift the pin 149, the block 166 emerges from the slot 167 and can then be moved along the slot 158 by the floating lever 170. If the heald is to stay in the same position for the next pick, the upper end of the floating lever will be kept stationary by the pattern mechanism but the lower end will follow the previous movement of the jack lever 116 (the movement of which has been stored as a deflection of the spring 171); as a result, the block 116 comes out of register with the slot 167, so that when the bellcrank lever 152 is released by the cam 156, it is unable to turn owing to contact of the block 166 with the unslotted part of the bracket 168. A subsequent movement of the upper end of the floating lever 170 will change the position of the heald by bringing the block 166 into its mid-position where it can rise up the slot 167 and so allow the locking ping 149 to drop into a notch 148. Instead of providing horizontal and vertical slots 158, 167, the bellcrank lever 152 may have a notch in its upper edge, the block 166 being constrained to move horizontally so that the bellcrank lever can turn only when the block registers with the notch.

Abstract: 731,239. Electric irons. HOOVER, Ltd. Dec. 24, 1953 [Dec. 24, 1952], No. 35857/53. Class 39 (3). [Also in Group VIII] A domestic iron has a sole plate formed with a horizontal groove 22 open along an inner side, and an electric heater 24 of rod type is retained in the groove so as to close its open side, leaving at its opposite side a passage through which steam passes from a boiler 17 to steam outlet ports 29 leading to the ironing surface. The heater is of U-shape and is inserted horizontally from the rear to bear on shoulders 26 of the groove, the upper wall 27 of which is thin and is swaged down to lock the heater in place. The rear parts of the element are outwardly offset, and the ends of the steam passage are completely sealed thereby. A cavity 17 in the thickened toe of the plate forms a flash boiler closed at the rear by the heater 24 and communicates by a port 18 with a semicircular steam passage 19 leading through ports to the steam passage 22. A boiler cover-plate 35 extends over the boiler and the steam passage 19 and is removable to allow cleaning of the ports. Water is poured at 46 into a reservoir 11 whence it passes by a metered orifice 31 of a valve 38 with a valve stem 39 in an aperture in the cover-plate 36 to the flash boiler 17. A bed-plate 48 is attached to the inner thinner part of the sole-plate by screws at the rear and at the sides has lugs 49 connected by stud bolts 51 attached to lugs projecting inwards from the thick periphery of the sole-plate. The plate 48 cairies a thermostatic switch 14 controlling the heater and attached to terminal strips 55. A cover shell 12 is attached by screws 61 to the front and real pillars of the handle 13 and fits over the reservoir 11, being secured by an assembly bolt 62 to the sole-plate. The valve stem 39 may be moved by an actuator 41 against a spring 44 so as to close the water inlet valve 38 in order to use the iron dry. The lower ends of the steam outlet ports 29 are enlarged to allow steam to pass to shallow grooves extending in herring-bone fashion across the ironing surface of the sole-plate, or the steam may issue through the thick rim of the sole-plate or through its upper surface.
