Title: Method of Making a Blade
IPC: B22D19/00
Filed: 1980-06-19
Abstract: The invention relates to a method of making a cast metal blade for a gas turbine engine with a closure for an internal cooling passage, and to the blade made by this method. According to the method a composite casting core is formed from two materials, the first of which (17) defines a cavity 31 within the metal blade Fig. 5 while the second of which (15) forms a closure for this cavity. The core is used in the conventional lost-wax coating process to provide a shell mould 29, Fig. 4 but only the part (17) of the core made of the first material is leached out after casting. This produces a cavity (31) closed by the piece (15) of the core left in situ. <IMAGE>

Title: Fuel pipes
IPC: F16L57/00
Filed: 1980-07-18
Abstract: A fuel pipe (10) is enclosed by a slightly larger diameter second pipe (16) so that a substantially annular gap (17) is defined between them. The arrangement is such that any fuel leaked from the fuel pipe (10) is contained by the second pipe (16). The fuel pipe (10) is provided with a coating (21) of polytetrafluoroethylene which serves to prevent frettage between the fuel and second pipes (10) and (16) and also reduces distortion of the second pipe during pipe bending as well as generally functioning as a lubricating member between the pipes. Alternatively the coating may be provided on the internal surface of pipe 16. <IMAGE>
Patent GB-2060977-A (GB)
Title: Variable speed tone arm control system
IPC: G11B3/085
Filed: 1980-09-30
Abstract: A tone arm control system includes first and second manually operated keys for providing input signals to a control circuit. The control circuit detects which one of the keys is operated and drives a vertical motor in the tone-arm upward direction and subsequently drives a horizontal motor in a tone-arm horizontal direction depending on which one of the keys is detected as being operated. The control circuit includes a counter which starts counting clock pulses to detect when a predetermined count is reached. During the predetermined count period the horizontal motor is energized at a low voltage to move the tone arm at a relatively low speed. When the clock count exceeds the predetermined value the speed of the tone arm is increased to allow it to speedily approach a desired position located relatively remote from the tone arm. <IMAGE>

Title: Drapery fabric foam backing
IPC: D06N3/00
Filed: 1980-12-10
Abstract: A method of making a foam backed drapery fabric or the like having good textile properties, and the fabric so produced. A wet foam backing is applied to a moving web of fabric, flocking is optionally applied to the wet foam backing, and the backing is at least partially dried without significant curing. The backing is then embossed with a patterned roller, and an aqueous solution containing a release agent and a wetting agent is kiss-coated to the foam backing to penetrate the foam backing without substantial penetration of the fabric, the aqueous solution being applied at about 50 to 80% pickup on dried foam solids weight. Where a curing oven containing rollers is utilized the foam backing is then dried, and then passed to the curing oven. The final fabric has good textile-like feel, softness, drape, abrasion resistance, and appearance characteristics, and the embossed backing is capable of recovering in five seconds to one minute after 3,000 psi has been applied for five minutes.

Title: After Treatment of Printed Matter
IPC: B41M7/00
Filed: 1981-10-28
Abstract: Printed matter is produced by printing onto absorbent, low quality paper, and then to prevent the ink pigments which are left on the surface of the paper after the liquid components have been absorbed into the paper from being rubbed off, a fluid, transparent solvent containing a binding agent is applied to the printed surface to bind the pigments of the ink onto the paper. The binding agent may be a synthetic resin such as an alkyd resin. The same solvents and binding agents may be used as are contained in the ink used for the printing. In a printing machine adapted to produce such printed matter, a coating device is situated sufficiently far downstream of the printing unit to ensure that the ink is dry by the time it reaches this coating device.

Title: Paper manufacture
Inventor: VANES DAVID CLIFFORD
IPC: D21H17/55
Filed: 1982-07-21
Abstract: A method of making paper by depositing cellulose fibres as a layer from an aqueous suspension, and dewatering said layer of cellulose fibres, in which method, to improve the dry strength of the paper product, the cellulose fibres are treated successively with a cationic non- formaldehyde polymer and an anionic polymer which is an aminoplast resin whose repeating unit is anionic. The method can be employed to give paper of usefully improved dry strength, without generating an unacceptable level of free formaldehyde in the working environment. Treatment of the cellulose fibres is preferably carried out by successively adding the cationic polymer and the anionic polymer to the aqueous suspension from which the cellulose fibres are deposited.

Title: Cable joint protection
Inventor: POKOJNY RUDOLF
IPC: H02G15/18
Filed: 1983-05-03
Abstract: This invention relates to the mechanical and environmental protection of cable joints, especially in power or other current-carrying cables. Disclosed is a recoverable sleeve which conforms closely to the cable joint, and a liner which bridges the joint and comprises a plurality of elongate elements assembled into a sheet. Flexible means is provided for holding the elements in a side-by-side arrangement and allowing the separation between the elements to vary to allow the liner to conform to the profile of the cable joint. Such flexible means may extend across the element and provide a water vapour barrier. Disclosed also is a method of protecting a cable joint utilizing the sleeve and liner. Where the cables to be jointed have metal armor, screen and/or shielding, the elements may be fabricated from metal or metal alloy and may then provide both armoring and a fault current path across the joint. Use of these more closely conforming joint case assemblies improves heat transfer and reduces the overall size of the joint.

Title: Optical data retrieval system for multi-characteristic reflective data storage media
Inventor: DREXLER JEROME
IPC: G11B7/24
Filed: 1983-07-26
Abstract: In a system for recovering data, both prerecorded (e.g. servo track) and user data, from a reflective optical data storage medium, with the further capability of distinguishing data from foreign particulate matter on a data disk 65, a pair of detectors 71, 77 measures the fraction of light 73 (e.g. infrared laser light) reflected from and the fraction of light 75 transmitted through the data disk 65 and, knowing the fraction of light absorbed by the disk 65 distinguishes user data from prerecorded data and particulate matter. Third detector T2 samples laser 61 output the data disk 65 has different optical characteristics for prerecorded and user data, the prerecorded information being black, highly absorptive silver, while the user data consists of pits or relatively high transmissivity in a reflective field. Particulate matter is recognized by intermediate reflectivity and transmissivity. The optical characteristics of the material are enhanced or exaggerated so that the two types of data and particulate matter can be distinguished. Record carrier constructions are detailed (Figures 2, 3, 4), as are materials (silver halide emulsion type) and processing thereof. A pattern may be located in layer (29) for security purposes. A quarter wave plate is used in the (Figure 7) system. <IMAGE>

Patent GB-2129408-A (GB)
Title: Feeding fabrics to welting machines
Inventor: WHITEHOUSE STEPHEN
IPC: A41H43/02
Filed: 1983-10-26
Abstract: An apparatus which prevents the edge of a fabric from curling under the fabric before the edge is welted comprises an air jet (16) which forms a cushion of air beneath the fabric edge as the fabric is moved to the welting machine (14) by a conveyor (12). The air jet (16) is switched on and off in response to the fabric workpiece passing sensors (24), (26). A plate (18) with upturned edge (22) helps to contain the cushion of air. The apparatus allows a welt to be stitched on fabric such as single jersey fabric which has a tendency to curl at the fabric edges, without the additional steps which normally have to be taken and which render the welting process highly inefficient. <IMAGE>
