Title: Improvements in shuttleless weaving looms
IPC: D03D47/40
Filed: 1957-07-12
Abstract: 819,705. Forming selvedges in shuttleless looms. ANCET, V. M. J;, and FAYOLLE, M. July 12, 1957 [July 19, 1956], No. 22098/57. Class 142(2) In a shuttleless loom in which weft is drawn through the shed from a stationary supply by a reciprocating needle 1, a selveedge is formed by a hook 38 which is rotated to engage the weft end, and is withdrawn to draw the end back into the shed and then out between the marginal warp threads. The ends may be cut subsequently or left to form a fringe. The hook is actuated by a cam operated rod 41, via an arm 22, a sector 20, and a pinion 19, a tube 10 and a concentric shaft 12, bevel gears 27 28, an arm 29 and further gears 35, 36. Initial movement of the rod 41 causes rotation of the hook the tube 10 being held stationary by brake shoes on arms 25 (Fig. 2). Further movement of rod 41 causes a face 60 on a plate 18 to engage a pin 17 whereupon the tube 10 turns and the hook, which is not now rotating, passes through the warp threads adjacent the weft end which is lightly held by auxiliary warps 42. The movement of rod 41 is now reversed and the hook rotates one revolution to engage the weft end and then the tube 10 turns and withdraws the hook and the end through the warp. The weft ends are cut by a device 45 containing rotary brushes and cutters connected to a suction pipe. The cutters and brushes are driven by a chain and sprocket 47, 48. The warps 42, which may be nylon, may be endless or may be fed from the warp of an auxiliary beam and pass through the healds, or through additional healds to the take-up roll.

Title: Sealing washer for mechanical seals
IPC: F16J15/34
Filed: 1972-05-11
Abstract: 1373145 End-face seals CRANE PACKING CO 11 May 1972 [6 July 1971] 22159/72 Heading F2B The sealing washer 10 of an end-face seal for a pump is made of frangible material and is compressed radially adjacent one axial end by a band 23 which also serves to transfer heat from the washer to a surrounding fluid adjacent its opposite axial end. The washer may be made of ceramics or carbon and mounted on a rotary shaft 19 by a resilient ring 20. The band 23 is formed with a taper to have an interference fit around the end adjacent the sliding sealing face 11 and is made of a material, such as an alloy of iron and nickel, which has a coefficient of thermal expansion close to that of the washer in order to maintain the washer under a constant state of compression when subject to thermal shock. The band is flanged to provide a cooling fin. Instead of the washer 10 being circular, it may be polygonal.

Abstract: 1,197,878. Dimerizing olefins. IMPERIAL CHEMICAL INDUSTRIES Ltd. 20 Feb., 1969 [4 March, 1968], No. 22271/69. Divided out of 1,195,307. Heading C5E. [Also in Division B1] Olefins are dimerized or co-dimerized using as catalyst a pre-formed SiO 2 -Al 2 O 3  co-precipitate impregnated prior to calcination with a nickel compound wherein the alumina content of the catalyst is 0À1 to 5% by wt. The nickel content of the catalyst may be 2-12% by wt. calculated as metal. Aqueous nickel salts such as sulphate, chloride or nitrate may be used to impregnate the coprecipitate which remain in traces after calcination to form the oxide. The catalyst may also contain up to 10% MgO coprecipitated with the silica-alumina. The dimerization may be effected in the gaseous phase, or preferably, the liquid phase at 0-120 C. Examples describe the dimerization of propylene and the co-dimerization of propylene and isobutylene using catalysts slurried in monomer.

Title: Instrument for the automatic determination of moisture in paper or textiles
IPC: G01N25/00
Filed: 1924-09-22
Abstract: 228,477. Harvey, A. R. Sept. 22, 1924. Drying.-In the automatic determination of moisture in paper or textiles, such as is required in the drying of paper in the process of manufacture, thermo-couples 17 are fitted to the cylinders 15, 16 to indicate the temperature of the paper before and after the drying cylinder 5. The heating of t'he cylinder 5 is effected by a resistance 6, Fig. 2, insulated by asbestos 7, 8, and the current is measured by a watt-meter. The thermo-couples 17 are connected to a milli-voltmeter or potentiometer, which is preferably calibrated to read in terms of per cent moisture in the paper according to the expression (T2- T1) (Ww x Sx + Wp x Sp) = Q where T2 is the temperature at' 16 T1 " " " " 15 Ww " " weight of water Sw " " specific heat of water Wp " " weight of dry paper Sp " " specific heat of the dry paper Ww is the only unknown and can thus be calculated, as also the per cent moisture from the expression Wu / Wp + Ww x 100 The rolls 15, 16 are supported in arms and may be thrown back to facilitate threading of the paper about the drying rolls. A suitable member may be carried by the pointer of the milli-voltmeter to give a graphic record on a recording sheet. Thermo-couples may be spaced along the rolls 15, 16, thus giving the variation in moisture content at' different points across the web. The apparatus may be arranged to work at a fixed rise in temperature, the heat variation being then measured.

Title: Method of manufacturing plastic sheet material with pearl essence incorporated therein
IPC: B29C69/00
Filed: 1955-08-03
Abstract: <PICT:0780458/IV (a)/1> Pearlescent material is produced by introducing a flowable composition of unsaturated polyester, pearl essence and peroxide catalyst into a preheated drum rotatable about a horizontal axis, the catalyst being added shortly before the composition is introduced, rotating the drum, the viscosity and temperature of the composition and the speed of rotation being such as to form a cylindrical layer of polymerized non-flowable material, and then removing the material while still in a flaccid condition, e.g. by cutting parallel to the cylinder axis.  The material may then be formed and allowed to set into a flat sheet, e.g. 1/8 in. thick. In the preferred process an unsaturated polyester/styrene mixture containing hydroquinone inhibitor and of viscosity 1000 to 1100 c.p.s. at 35 DEG  to 40 DEG  C., mixed with synthetic pearl essence or with fish scales in amyl acetate/diallyl phthalate, cobalt naphthenate promoter and a silicone oil lubricant, is heated to 40 DEG  C., a catalyst is added and the whole is agitated for about 3 minutes.  The mixture is then introduced into a 30 in. diameter aluminium drum 34 of a centrifugal casting machine, the inner surface of the drum having been coated with a silicone grease mould release agent, and the drum being rotated on idler and drive wheels 20, 24 to ensure even distribution.  The drum is then rotated at 40 revolutions per minute for 30 minutes while the temperature is maintained at 40 DEG  C. by infra-red lamps 40.  The flanges 38 retain the material in the drum as well as engaging the drive wheels during the operation. Catalysts specified are hydrogen and methyl ethyl ketone peroxides and cyclohexyl hydroperoxide.  The polyester resin preferably contains a film-forming ingredient, such as paraffin, in order to obtain a tack-free surface, but otherwise talcum or corn starch may be spread over a tacky surface obtained.  Pieces, e.g. imitation pearl button blanks, are punched from the flaccid material in the flat sheet stage before it sets completely.

Filed: 1948-08-26
Abstract: 653,137. Machinery guards. PRESS GUARDS, Ltd., and EVANS, F. A. Aug. 26, 1948, No. 22490. [Class 80(iv)] A vertically movable guard I of a power press is adapted to close from the raised position shown by gravity and to be raised by pressure fluid admitted below apiston secured to the guard of a cylinder n through a manually controlled valve r. A switch t in the starting circuit of the machine is adapted to be operated to close by a projection on' the guard only when the guard is in its fully closed position and the guard is held in the closed position, whilst the machine is operating, by air pressure used for actuating the clutch of the machine also acting above the piston of cylinder n through a pipe s. Obstruction of the guard in its closing movement results in a pivotal movement of an auxiliary part u for stop pawls v thereon to engage stationary racks w to arrest further movement. A stationary bottom guard portion x may also be provided and may be adjustable. In a modified arrangement the guard co-operates with a valve controlling the supply of pressure fluid to actuate the machine clutch so that the valve is opened to engage the clutch as the guard reaches its fully closed position.
