Title: Stripping conductive cables
IPC: H01B7/38
Filed: 1980-04-21
Abstract: A conductive cable (10) having a conductive core (11) and a protective jacket (15) of plastics material moulded around the core, also contains a guide member, in particular a plastics guide tube 14, below the jacket and into which a jacket slitting tool can be inserted. By pushing the slitting tool along the tube, the jacket can easily be slit, the tool cutting through the side of the tube adjacent the jacket whereas the side of the tube adjacent the core guides the tool along the cable and protects the core from damage by the tool. If the cable contains metal screening (Fig. 2 not shown), the guide tube is located between the screening and the jacket. <IMAGE>

Title: Dispensing tip
IPC: B65D47/18
Filed: 1980-07-15
Abstract: A dispensing tip for a container of cyanoacrylate adhesive (45) has a stopper initially attached to the tip at a weakened junction which is broken, the stopper inverted and then replaced, whereby a plunger (32) penetrates a passageway (58) to force excess adhesive back into the container, prevent clogging, and close the passageway. The stopper is retained on the tip by engagement of ridge (40) in groove (28). A two phase interlock secures a rotatable cap (60) to the container and includes flanges (84) extending from the cap for releasably engaging lugs (82) located about the mouth of the container. A key extends from the cap (60) into a key way in the container to prevent rotation of the cap relative to the container unless the key is deliberately withdrawn from the key way by flexing of the cap. <IMAGE>

Retaining means e.g. shoes 25 are provided adjacent the trolley wheels, and, as the trolley is pushed onto the escalator, first the front shoes and then the rear shoes are pulled, by the activated magnets down into engagement with the tread plates of the relevant steps to hold the trolley on the escalator. <IMAGE>
Patent GB-2060436-A (GB)
Title: Method of applying a ceramic coating to a metal workpiece
IPC: C23C4/02
Filed: 1980-09-02
Abstract: A method of applying an adherent ceramic coating to a metallic workpiece is proposed in which the workpiece is heated above 500 DEG C and the coating directly plasma sprayed thereon before the workpiece has formed any considerable oxide skin thereon. In this way the use of the conventional bond coat is avoided, while the amount of tensile temperature is reduced by the pre-stressing effect thus induced.
Patent GB-2063626-A (GB)
Title: Improvements in or relating to circuit arrangements for identifying alignment words for use in digital signal transmission systems
IPC: H04J13/00
Filed: 1980-09-18
Abstract: A circuit arrangement is provided for identifying an alignment word of m bits from a demultiplexer DM of a digital communication system having n channels. The circuit arrangement Fig. 2 (not shown) includes a memory comprising n shift registers of length (n + m)/n for receiving n bit flows from the demultiplexer DM. A decoder DC energizes one of its n outputs according to the way in which the bits of the alignment word have been distributed in the shift registers of the memory. A coder CM provides a code q corresponding to the energized output, where n</=2<q>, and supplies this code as a control signal to an exchange matrix MS which reorganizes the n bit flows, if necessary, into n bit flows of the n channels. Thus, the demultiplexer output is aligned by the circuit arrangement, which is only required to operate at 1/n times the speed of the demultiplexer.   <IMAGE>

Title: A check valve
IPC: F16K15/03
Filed: 1980-10-10
Abstract: A check valve has a valve body with a chamber therein, an inlet in the valve body to the chamber and an outlet in the valve body from the chamber. A valve seat is provided on the inlet in the chamber, a valve closure member 16 within the chamber for seating on the valve seat to close the inlet, and means for mounting the closure member above the valve seat so it can move with both linear and curvilinear movement away from the valve seat to open the inlet. A support plate 17 for the closure member 16 includes a pair of laterally extending arms 28, 29 which rest on horizontal bearing surfaces defined by the valve body. A pin 30 extends through the valve body into a slot 31 in the plate 17 and permits limited linear movement of the closure member 16 prior to pivoting thereof. <IMAGE>

Title: Shackles
IPC: F16G15/04
Filed: 1980-11-25
Abstract: A shackle 1 for a chain suspension for a lift-on lift-off skip has a safety flap 7 in the top of the shackle aperture 2. The flap 7 is pivotable against spring 9 around a pivot 8 extending transversely of the shackle aperture axis and, in the locking position, bears by way of side members 10, 11 on the shackle arms 12, 13. The pivot 8 is offset from the shackle aperture centre plane 18; also, the flap 7 has a distal part 19 disposed between the shackle arms 12, 13. The side members 10, 11 lie in a plane offset outwardly from the flat distal part 19 and are so arranged that at least one of the side members of the flap projects laterally beyond the shackle outer periphery (as at 11a). The flap extends closely around the suspension pin in the locking position but cannot jam if the shackle tilts; consequently, if the chain slackens and the shackle becomes inclined, the shackle can be opened and moved past the pin head. <IMAGE>

Title: Joint for conveyor pans
Inventor: TURNER WILLIAM JOHN
IPC: B65G19/28
Filed: 1981-10-07
Abstract: A conveyor, for example a so- called sigma-section chain conveyor, comprises a number of pans connected by one or more flexible links. Each such link comprises a male member 39 having an aperture therein, and a pair of members 61, 62 providing a clevis- form female member each with an aperture therein, and a connecting pin 77 passing through the aligned apertures.

Title: Improvements in or relating to pipes for irrigation and other uses
IPC: B29C53/36
Filed: 1982-02-18
Abstract: A flexible fluid-pervious pipe for use in irrigation and similar applications comprises two tubular members 1, 2 one within the other. The inner tubular member 1 is formed from a sheet of permeable material such as non-woven polyolefinic film- fibril material and the outer tubular member 2 is made from a needled impermeable material such as an unwoven, flocked polyester. The inner tubular member controls the egress of fluid from the pipe and the outer tubular member protects the inner member from attack by insects. The tube may be made by joining the edges of the inner member 1, wrapping the outer member 2 thereabout to leave a gap between its edges and sealing the two members lengthwise by application of welding material 5 in the region of the gap. <IMAGE>

Title: Metal plating compositions and processes
IPC: C25D3/56
Filed: 1982-02-25
Abstract: A bath composition for electroplating a bright alloy deposit of cobalt and tin or cobalt and zinc on a substrate, is characterized by the presence of a brightening amount of a compound having the formula:   <IMAGE>  wherein: R<1> represents an alkyl group having 1 to Y carbon atoms or an alkyl group having from 1 to Y carbon atoms at least one of which is substituted by a hydroxyl group; and R<2> or R<3> or both represent a hydrogen atom or an alkyl group of 1 to Y carbon atoms or an alkyl group of 1 to Y carbon atoms at least one of which is substituted by a hydroxyl group or an amino group and R<2> and R<3> may be the same or different and may be the same as or different to R<1>, Y being an integer from 2 to 6 and preferably 2, 3 or 4. The invention is based on the discovery that addition of the amino alcohol compounds enhances the brightening of deposits incorporating tin and cobalt or zinc and improves the process, rendering it capable of producing good deposits with less careful control on the thickness of the coating being required.
Patent GB-2100710-A (GB)
Title: Amorphous silica-based catalyst and process for its production
Inventor: BARNES DAVID IAN
IPC: C10G3/00
Filed: 1982-04-20
Abstract: The catalyst comprises a highly porous amorphous silica having a monolayer of an amphoteric metal (e.g. Al, Zn, Mg, Zr, Ti) chemically bonded onto up to 90% of the surface area of the silica matrix. The catalyst has a maximum pore diameter of 1.5nm and the metal is preferably aluminium. The catalyst is produced by treating the silica with a solution of a hydrolysable aluminium compound, removing the solvent and causing the silica surface to hydrolyse the compound, thus chemically bonding the aluminium onto the surface of the silica matrix. Optionally, the catalyst is mixed intimately with a Fischer- Tropsch catalyst to enable the direct conversion of synthesis gas to hydrocarbons. The catalyst will be of use in the conversion of synthesis gas or methanol to higher hydrocarbons.
