Patent GB-2220626-A (GB)
Title: Parachutes
Inventor: KING IAN LESLIE
IPC: B64D17/14
Filed: 1988-06-28
Abstract: A parachute canopy (1) has a skirt (5) extending around its lower peripheral region. The upper portion of the skirt (5) is secured directly to the canopy (1) and its lower free edge portion (6) is connected to the peripheral hem (3) of the canopy (1) by a plurality of tie elements (7). During deployment of the canopy, the skirt (5) inflates to force the lower region of the canopy (1) radially outwardly to aid its opening. The ties (7) may be such that they fail at a critical deployment velocity allowing inversion of the skirt so as to avoid excessive opening shock loads. For example, the ties (7) may be connected to the rigging lines (4) in such a way that they will be snapped by the tension in the rigging lines (4) when this exceeds a critical value. <IMAGE>
Patent GB-2209805-A (GB)
Title: Dispensing valve assembly
Inventor: MCNAIR LEONARD IVOR
IPC: B65D83/14
Filed: 1988-09-14
Abstract: A dispensing valve assembly for an aerosol container is provided in which, when the dispensing button is fully depressed a flow path for propellant is established through inlet 32, chamber 28, hole 14 and passage 12 in the valve stem and at the same time a flow path for product is established from dip tube 24 through recess 36, inlet 34, chamber 28, hole 14 and the passage 12 in the stem. However, when the button is only partly depressed, a sealing flange 30 at the bottom of the valve stem isolates the product inlet 34 and so only the propellant flow path is open. Consequently, for a brief period when the button is being released there is a flow of propellant only through the dispensing passageway which clears it of product. Thus products such as paint which may dry out in this passageway and clog it are not given the opportunity to do so. <IMAGE>

Title: A contact printer
Inventor: CASPERSEN HENRIK
IPC: G03B27/18

Title: Waterproof roofing and lining membranes
Inventor: ADDISON DEREK WILLIAM
IPC: B32B27/32
Filed: 1989-10-09
Abstract: The membrane comprises a layer of Chloro-Sulphonated Polyethylene (CSPE), a reinforcing layer (e.g. scrim, plastics or metal foil), a self adhesive layer applied to the reinforcing layer, and a layer of release backing paper applied to the surface of the adhesive layer which can be peeled off prior to cold bonding the membrane to an underlying surface. The membrane may be produced by feeding a first web (1) of CSPE heated to around 130 to 140 DEG C to heated calender rolls (4, 5), feeding a second web (6) of the reinforcing layer to said calender rolls, bonding these webs together at approximately 120 DEG C, feeding a third web (7) of release backing paper towards the bonded first and second webs via applicator rolls (8 to 10) which apply adhesive compound at around 160 - 180 DEG  C as a coating to one surface of the backing paper, and laminating this coated surface to the adjoining surface of the reinforcing layer of the bonded first and second webs at around 80 - 100 DEG C. <IMAGE>

Title: Mounting bracket for vehicle engine tie-bar
Inventor: JONES JOHN BERNARD
IPC: B60K5/12
Filed: 1989-10-10
Abstract: The mounting bracket consists of a cranked plate (4) and a cranked link (3), attached e.g. to the clutch housing (5), to enable an engine stabiliser tie-rod (1) to be connected to the cylinder block (2) e.g. of an Austin Mini (R.T.M.) by an external nut (7) instead of the threaded hole (8) which may have become stripped after repeated removal and refitting of the tie-rod (1) in order to replace its rubber bush. The bracket (3, 4) allows easy fitting of the tie-rod (1) and isolates the rubber bush from engine heat and oil thus prolonging its life. <IMAGE>

Title: Detecting diamond particles
Inventor: HANSEN JOHN OLAF
IPC: G01N21/41
Filed: 1990-06-12
Abstract: Diamond particles are distinguished from non-diamond, associated particles on the basis of their higher refractive index. The particles are brought to a specific location, typically in a stream of water flowing full in a vertical duct 10, and a beam of collimated electromagnetic radiation (from a source 16) is directed at them. An array of radiation detectors 18 is provided to detect refracted and/or reflected radiation. The array is so configured that the responses of the detectors, considered collectively at 24, will be indicative of the presence of a diamond when a diamond is in fact present. However, when a particle having a substantially lower refractive index is present, the response of the detectors will not be so indicative. The diamond and non-diamond particles can subsequently be sorted from one another at 26. <IMAGE>

Title: Magnetic disc apparatus
Inventor: IKEDA JUNICHI
IPC: G11B21/02
Filed: 1990-06-15
Abstract: The invention is directed to a magnetic-head support structure in a magnetic disc apparatus, in which at least one magnetic head for writing and reading magnetic information with respect to at least one disc is mounted to a forward end of an arm which moves over a side of the disc. A pivot shaft is provided out of a rotational range of the disc, substantially in parallel with the disc. An elastic element in the form of a belt is wound about the pivot shaft. The elastic element is fixedly mounted to a part of the arm at a region except for a range within which the elastic element is wound about the pivot shaft, so that the elastic element is prevented from slipping in a circumferential direction of the pivot shaft. Rotation of the pivot shaft causes the arm, via the elastic element, to move in an angular motion over the disc surface. <IMAGE>

Title: Method for forming triniobium tin superconductor
Inventor: BENZ MARK GILBERT
IPC: C23C2/08
Filed: 1992-06-22
Abstract: A method of forming superconducting triniobium tin tapes by coating a niobium tape in a tin bath and reaction annealing the coated tape to form triniobium tin is improved by coating the niobium tape in a tin bath comprised of about 5 to 25 weight percent copper, about 5 to 25 weight percent lead, and the balance substantially tin. The niobium tape may comprise up to about 5 atomic percent of a solute selected from Zr, Hf, Mo, U, Re or mixtures thereof and up to about 10 atomic percent oxygen. The load, copper, and tin alloy coating promotes rapid formation of a fine grained triniobium tin during reaction annealing of the coated tape. The fine grain size in the triniobium tin provides improved current-carrying capacity in the superconducting tape. The lead, copper, and tin alloy coating that remains on the triniobium tin after reaction annealing also improves the solder bonding of a non-superconducting of copper outer laminae to the triniobium tin. As illustrated in Fig. 3 excess coating of tin alloy 4' covers the triniobium tin on the remaining tape 2'. <IMAGE>

Title: An adjustable-throw crank mechanism
Inventor: PAPIN JEAN-PAUL
IPC: F04B13/00
Filed: 1992-07-03
Abstract: A device for transmitting a rotary motion into a variable reciprocating linear motion incorporates an Oldham coupling 8 having an input 6 with a fixed axis A and an output 10, a disc-shaped plate located between the input and output having projecting keys 12, 13 which are received in respective orthogonal grooves formed in the opposed faces of the input 6 and output 10. The output 10 is mounted for transverse movement on a carriage 16 and a coupling rod 21 with a head 22 coaxially surrounds and is freely rotatable on the disc-shaped plate, which forms a hub, the coupling rod engaging an element 2 which is movable linearly in a reciprocable manner which forms the output of the arrangement. The movement of the axis B of the output 10 of the Oldham coupling, by a screw-and-nut arrangement, relative to the axis A of the input causes variable eccentric motion of the disc-shaped plate, the intermediate member of the coupling, and thus variable reciprocation of the final output 2. <IMAGE>

Title: Manufacture of foamed seat pads
Inventor: CARTER NEIL KEVIN
IPC: B29C44/34
Filed: 1993-08-14
Abstract: Foamed seat pads are manufactured in a female mould 10 by using vacuum applied through a chamber 18 and a series of holes 20 (Fig 1, not shown) in the mould wall to draw a fabric seat covering layer 22 into contact with the mould inner wall closing the mould with a fabric clamping ring 14 (Fig not shown) and a lid 16 and then introducing a foam 26 which fills the internal space in the mould. The clamping ring 14 has vent apertures 25 along one edge where the covering layer extends outside the closed mould, and the mould is arranged so that this edge is uppermost as the foaming reaction takes place. Any foam which escapes from the mould through the vent will then be trimmed off when the covering layer 22 is trimmed. <IMAGE>
