IPC: A47C27/14
Filed: 1972-02-04
Abstract: 1415852 Foam-fabric laminates; moulding upholstery HAIRLOK Ltd 22 Jan 1973 [4 Feb 1972] 5336/72 Headings B5N and B5A [Also in Divisions A4 and B2] A shaped padding or like article of upholstery includes or consists of a covering in which a polymer foam capable in itself of giving full shape retention to the article is bonded directly or indirectly to an outer textile wear layer, said polymer having been made as a foamed sheet not bonded to a textile and having been shaped by thermoforming before or after application of the textile. The textile may be an extensible woven or knitted fabric of crimped or elastomeric yarn, a bonded or felted non-woven fabric, a loop pile fabric or a fabric deposited by electrostatic flocking, and may be of urethane, cotton, rayon, nylon, wool, acrylics, polyester or cellulose acetate, knitted nylon fabrics being preferred. The foam may be of cross-linked closedcell polyethylene or of polyvinyl chloride. The fabric and foam may be bonded by polyurethane adhesive, by flame-treatment possibly with a polyesterurethane foam interlayer, or by a thermofusible powdered ethylene-vinyl acetate copolymer or polyethylene. The articles may include a backing foam layer which may be formed in situ on the covering, either by applying a cold-cure polyurethane foam to a vacuumthermoformed covering or by expanding the foam in a heated mould in which the unformed covering is disposed, or may be pre-formed. Its adhesion may be assisted by neoprene rubber or polyurethane adhesive, by corona discharge treatment or by flame treatment possibly with a polyesterurethane foam interlayer. The foam of the covering may be perforated to assist sound absorption into an open-cell cushioning layer. In examples, seats, carpets and trim for cars are prepared.

Abstract: 1438243 Dispensing liquids BAR-O-MATIC SALES CO 6 Feb 1974 05434/74 Heading A4T Apparatus e.g. for dispensing drinks comprises a reservoir 12, preferably for receiving liquid from an inverted bottle 11, 11', a delivery chamber 30 from which the liquid may be discharged by gaspressure, a chamber 32 for pressurizing the liquid, a first valve 37 for controlling flow from the reservoir 12 to the pressurizing chamber 32 and a second valve 42 for controlling liquid and gas flow between the chambers 30, 32, the valves 37, 42 being co-operable to pressurize and supply quantities of liquid from the reservoir 12 to the delivery chamber 30. Two similar dispensing apparatus 10, 10' may supply a common handheld nozzle 13 e.g. for producing mixed drinks, and pressure is supplied through manual valves 17, 17 and automatic shut-off valves 18 to inlets 15. On discharging liquid through an outlet 20 under the gas-pressure, a float 43 is lowered, a rod 55 being pulled downwards to engage a portion 54a of a valve-member 54, which is thus pulled out of engagement with a valve seat 52. The gaspressure thus flows through a tube 53 surrounding the rod 55, through the valve seat bore 52a and through an outer tube 56 to pressurize the liquid in the chamber 32. When the pressure in the chamber 32 has thus built up, the valve-member 44 of the valve 42 is no longer held against its seat 46 by the pressure differential so that the member 44 falls, allowing the pressurized liquid to flow through an opening 41 into the chamber 32, and closing the valve 52. Pressure within the chamber 32 retains means 39 on a float 38 of the valve 37 in engagement with a seat 40 as the chamber 32 empties, the float 43 rising on the transferred liquid to close the valve 42, and the pressure within the chamber 32 is vented through a tube 57, so that the float 38 falls, opening the valve 37 to allow liquid from the reservoir 12 to flow into the chamber 32 until the float once more causes the valve 37 to close.  Alternatively, Figs. 7 and 8 (not shown), flow between the reservoir and chambers may be controlled by simultaneously operated liquid and gas flow valves (60l), (60g), (611), (61g), a level sensor (62) in the delivery chamber (30') controlling operation.

Title: Improvements relating to the construction of concrete piles or columns
IPC: E02D15/04
Filed: 1921-02-17
Abstract: 179,689. Hiley, A. Feb. 17, 1921. Piles.-Concrete piles are constructed by means of a tube from which concrete is deposited and tamped and consolidated by vertical vibratory movements of the tube effected by a powerhammer. A tube B, Fig. 4, with a detachable shoe D and a protective tube F, is driven by a steam hammer or by a drop-weight suspended from a structure A. A steam or other hammer C, arranged to strike upwards on an anvil or casing, is then connected to the tube B by arms C' and suspended by springs C' from ropes C<5> passing over pulleys on the structure A to a winch. The tube is then filled with concrete through a shoot B<2>, and the hammer C started, giving a vibratory movement to the tube. Each upward blow of the hammer raises the tube and deposits a quantity of concrete in the hole, while the downward movement due to the weight of the tube tamps and consolidates the concrete. The lower end of the tube is provided with a ring B' to increase the tamping area. An upward pull on the tube is meanwhile maintained by the winch, and the tube gradually rises out of the hole, the shoe D being left at the bottom. The protective tube F is secured to the tube B when the latter has nearly completed its upward movement, and is withdrawn with it. Reinforcing- members may be placed in the tube B before filling in the concrete. Alternatively, the hole may be made by a driving-tube, which is additional to the tube B and which, when withdrawn, may leave a protective casing, between which and the tube B reinforcing-members maybe disposed. The casing and the tube are withdrawn simultaneously. In an alternative construction of the tube B, internal collars B<3>, Fig. 10, either continuous or interrupted, are provided of such form that the concrete can flow downwards during the upward stroke of the tube, but is forced downwards during the downward stroke. When it is desired to retain a charge of concrete in the tube while being lowered, a conical member B<4> is provided, which can be raised by a rod B<5> to act as a valve.

Title: Electrochemical shaping
IPC: B23H9/10
Filed: 1965-02-11
Abstract: A process for electro-erosion of material from an electrically conductive workpiece e.g. to produce a turbine wheel, comprises a first machining operation in which, in this instance, a turbine wheel blank 10 is brought into contact with an electrode tool 32 which moves progressively towards the workpiece 10, whilst the workpiece 10 is rotated in a prearranged manner as by means of a system comprising a cam slot 56 in block <PICT:1062343/C6-C7/1> 58 attached to the workpiece holder 22 and a pin 54 attached by a bracket 52 to the electrode tool 32, the teeth 42 of the electrode tool electrolytically machining corresponding slots in the peripheral edge of the workpiece 10, the shape of the slots depending on the shape of the electrode tool and upon the movement of workpiece and tool relative to one another, as defined by the cam mechanism. This rough shaping operation may then be followed by a second machining operation using a similar type apparatus, in which the electrode tool has a plurality of electrode segments or projections 74 integral therewith which will, on bringing the electrode tool progressively towards the workpiece, enter the slots formed therein by the first machining operation.  Subsequent rotation of the workpiece, controlled by a cam mechanism similar to that described above then brings the electrode segments into contact with the side faces of the corresponding teeth 62 of the workpiece, formed by the slots 60 cut therein, thus machining said teeth to a desired shape, in accordance with shape of the electrode tool segments and the relative motion of workpiece and tool.  This second machining may comprise the consecutive use of two different electrode tools, machining one side of the workpiece teeth with one tool, and the other side with a second tool, each tool being shaped in the required manner. Alternatively a single electrode tool Fig. 7 (not shown) may be used in which two electrode segments pass into each slot in the workpiece, the first electrode segment of each pair being mounted upon one disc and the second electrode segment of each pair being mounted upon a second disc, one disc positioned above the other in such manner that they may be rotated relative to one another, thereby bringing each electrode segment into contact with the side of the adjacent workpiece tooth simultaneously.  Electrolyte is introduced into the electrode tool 32 via the tube 48 and in the case of the second electrode passes to the workfaces via the slots 84. Electric conductors 44 and 46 are connected to electrode tool and workpiece holder respectively.
