Title: Resilient padded items
IPC: A47C7/18
Filed: 1973-01-31
Abstract: 1458664 Vacuum-forming stretchable fabric covers; laminates STOREY BROS & CO Ltd 30 Jan 1974 [31 Jan 1973] 4931/73 Headings B5A and B5N [Also in Division A4] A method of making a resilient fabric-faced upholstered item, e.g. interior trim and seats for cars comprises vacuum forming a laminate of an extensible textile fabric and a thermoplastics sheet to form a cover and holding the cover to shape in a female mould, e.g. by vacuum whilst a resilient foam is formed in situ within the cover. The fabric has an extensibility in at least one direction of at least 25% under a load of 5 lbs. per 2 inch wide strip. The fabric may derive its extensibility from the inherent nature of the yarns and filaments, e.g. crimped or coiled and/or from the fabrication of the fabric, e.g. loop-knitted fabric, e.g. knitted nylon 6, felts, non-woven and twill or sateen woven fabrics. The thermoplastics sheet may be 20- 2000Á thick, may be foam and may be formed of polyurethane, plasticized PVC or polyethylene. The laminate may be formed by joining the two components by adhesive or heat or by applying a paste or melt coating of plastics on to the fabric.

Patent GB-348654-A (GB)
Title: Improvements relating to the treatment of water
IPC: G05D11/13
Filed: 1930-02-15
Abstract: <PICT:0348654/III/1> <PICT:0348654/III/2> The automatic control of the addition of a sterilizing or other reagent to water is effected by adding a suitable indicator to a sample of the treated water and passing a beam of light through the sample on to a photo-electric cell, the resistance of which controls an electrically operated valve controlling the supply of the reagent.  The current passing through the photo-electric cell may be amplified by a thermionic valve.  In the arrangement shown in Fig. 1, two cells 18, 20 are connected in series and the grid of the valve 42 is connected to the point between them.  The lamp 22 irradiates the cell 18 directly and the cell 20 through the vessel 16 containing the sample, a change in the colour of which consequently affects the grid potential of the valve.  The anode circuit of the valve includes a relay 28 supplying current to the dosing valve 26 controlling the supply of reagent.  The liquid may be sampled continuously but the test is applied at intervals controlled by a time switch.  The dosing valve is constructed to open and close slowly and is locked in position between successive tests. Fig. 2 shows a needle valve 24 which opens when the core 50 is attracted by the solenoid 26 and closes under the action of gravity when the solenoid is not energized.  Both movements are retarded by the dashpot 52.  The valve is normally locked in position by the catch 58 which is released by the electromagnet 62 when a test takes place.  The valve then opens or closes according to the presence or absence of current in the plate circuit of the thermionic valve 42 and at the completion of the testing period is again locked by the catch 58.  Another form of valve is provided with two parallel racks arranged on opposite sides of a continuously rotated gear wheel and means are provided for bringing one or the other rack into contact with the gear wheel according to whether the relay 28 is energized or not.  According to the Provisional Specifications the test may be applied to the water before treatment and may give a signal instead of automatically controlling the valve.  This subject-matter does not appear in the complete Specification. Specifications 151,328, 264,237, and 282,168, [all in Class 1 (i), Chemical processes &c.], are referred to.
