Patent GB-2126564-A (GB)
Title: Turret winder
Inventor: KRIMSKY LEONARD C
IPC: B65H19/22
Filed: 1983-06-29
Abstract: A continuous winder turret carries winding spindles (20, 22) rotatable between an upper core loading/web guiding location and lower winding-unloading location. Each spindle has an associated angle roll (156) and lay-on roll (158) mounted on a support (38) which is adapted to move on rails so as to remain in continuous tangential relationship with the winding roll thereon as it increases in diameter. A web cutter is provided adjacent the lay on rolls to sever the web running to a fully wound roll and initiate winding on the new core. The angle roll (156) guides the web to provide a constant contact angle between the web and the winding roll and the lay-on roll (158) engages the winding roll at the point of contact of the web excluding air from between the wound web layers. During winding, the angle roll associated with the other (e.g. upper) winding spindle acts as a guide roll for the web being wound. <IMAGE>

Title: Anti-collision radar plotting aid
Inventor: JOHANNESSEN DR ROLF
IPC: G01S13/937
Filed: 1983-09-20
Abstract: A radar display in the form of a transparent LCD (14) is overlaid on a navigation chart (13a) so that a navigator can see target and track information obtained by a marine radar (11) in direct relation to the information on the chart, whereby to assist him in determining the best course for his vessel; for instance, the chart No. may indicate that a shipping lane alters course, and so that a ship on a potential collision course can be expected to change course, and so no evasive action is necessary. Hazards (such as shallow water) may also be shown. <IMAGE>

Title: Video processors
Inventor: TAYLOR RICHARD JOHN
IPC: H04N7/01
Filed: 1983-10-25
Abstract: A video signal processor for effecting field or frame rate conversion comprises a number of framestores 30-33 connected in series to receive incoming video signals under the control of a first generator 35, which signals are available from the respective field stores under the control of a second generator 36.

A comparator 52 determines if significant movement is present and modified co-efficients to the multipliers 42-49, made available from a coefficient control 53, so as to allow a single field to pass to the output. Otherwise the output field is generated from a plurality of incoming fields. <IMAGE>

Title: A creel
Inventor: ROBINSON ANTHONY JAMES
IPC: B65H49/10
Filed: 1984-02-27
Abstract: A creel (10) comprises a frame (14) mounted in a C-shaped support structure to be pivotal about its vertical central axis (17). The frame (14) defines four spaces (22) on each of three levels. In each space (22) are pivotally mounted a pair of rigidly spaced package support arms (24, 25) which are together pivotable between two operative positions offset towards each side of the space (22) so that a large diameter reserve package (12) can only be accommodated on one package arm (24) when the in-use package (11) on the other package arm (25) of that pair has been used sufficiently to reduce its diameter significantly. To this end, in each operative position, the median plane (31) between the support arms (24, 25) is spaced to one side or the other of the median plane (32) between the frame members (20) defining the space (22). This enables large packages (12) to be used in a creel (10) of lower height than would otherwise be required, to reduce package handling problems. <IMAGE>

Title: Deposition of gold-copper-zinc alloys
Inventor: SCHULZE-BERGE DR KLAUS
IPC: C25D3/62
Filed: 1984-12-17
Abstract: A process for the deposition of a low carat value gold-copper-zinc alloy from a gold-copper-zinc electrolyte that contains the zinc as alkali-zinc-chelate and also contains alkali cations. The alkali cations are sodium ions and are present in a concentration of 20 g/l<Na<+>< the solubility limit where Na<+> denotes the concentration in g/l of the Na<+> ions in the electrolyte. The chelate-former concentration lies in the range above 20 g/l. With such an electrolyte a gold-copper-zinc deposit is obtained that is resistant to the copper chloride test. The deposition of zinc is controlled by the chelate concentration.

Title: Diffusion bonding
Inventor: BALL MICHAEL JOHN
IPC: B23K20/16
Filed: 1985-11-27
Abstract: In a method of diffusion bonding metal parts, particularly of aluminium or aluminium alloy the parts are subjected to an oxide removing process including ion cleaning, depositing on the surface of the parts a relatively thin layer of material relatively immune to oxidation and then subjecting the parts to a bonding process. The parts are urged together at a temperature and pressure sufficient to allow diffusion bonding and the relatively thin layer is effectively dispersed on each of the parts without significantly affecting the physical properties of the metal. In apparatus for performing the method the coated parts are enclosed in a metal envelope which is evacuated. An adjacent envelope is pressurised, the whole unit being constrained between mould parts 11, 11'. <IMAGE>

Title: Pulverised fuel burner
Inventor: HELYER LAURIE EDWARD
IPC: F23D1/02
Filed: 1986-03-14
Abstract: A pulverised fuel burner comprises three coaxial tubes, an inner tube, an intermediate tube 2, and an outer tube 3. A dense phase mixture of finely pulverised fuel and steam is introduced into the annular passage 5 formed between the inner and intermediate tubes via a scroll type entry connection 4. The fuel/steam emerging from the end of the annular passage 5 is expanded and dissipated in the form of a hollow divergent conical stream by the hollow divergent cone 11. A combustion air supply is admitted to the burner via the air box 7, annular passage 8 and main flame stabiliser 10, which creates a swirling hollow divergent cone of air surrounding and mixing with the divergent cone of dissipated fuel particles and steam. The combustion of this diverging hollow cone of dissipated fuel particles and steam inter-mixed with the swirling matched air stream, is initiated by an igniter 12. After the short ignition period, combustion is continuously propagated by the hot gas recirculation within centre of the combustion zone thus maintaining combustion stability. A fuel oil injector may be inserted in the control passageway 14. <IMAGE>
