Patent GB-1269677-A (GB)
Title: Bleaching composition
Inventor: JENKINS PETER ANTHONY
IPC: C01B15/08
Filed: 1969-12-11
Abstract: 1,269,677. Bleaching composition. PROCTER & GAMBLE Ltd. 10 Dec., 1970 [11 Dec., 1969], No. 60531/69. Heading DIP. [Also in Division C5] A bleaching composition comprises a mixture of persulphate and an organic peroxycompound, in proportions such that the weight ratio of available oxygen derived from the persulphate to that derived from the peroxy compound is up to 3:1 and preferably 1:10 to 1:1. Fibrous materials are bleached by treating them in an aqueous solution containing from 1 to 100 p.p.m. by weight of available oxygen derived from the mixture of bleaching agents. Preferably the persulphates are alkali metal or ammonium persulphates and particularly the mixed salt MHSO 4 , M 2 SO 4 , 2MHSO 5  wherein M is K or Na. The organic peroxy compound is a percarboxylic acid or an alkali metal or ammonium salt of such e.g. perbenzoic acid or a nuclear substituted perbenzoic, especially those having a m.p.t. above 50‹C., e.g. p-methoxyperbenzoic acid. The bleaching agents may also contain organic detergents, which may also contain other ingredients such as inorganic builder salts and/or organic sequestrant builder salts. Particularly suitable organic detergents are the anionic detergents e.g. soap, alkylaryl sulphonates, alkane sulphonates, olefin sulphonates, fatty acid isothionates, and fatty aryl taurides. Suitable inorganic salts and builder salts include alkali metal ortho-, pyro and tripolyphosphates, carbonates, bicarbonates, silicates, sulphates and borates. Organic alkaline builder salts include nitrilo-triacetates, ethylenediamine tetra acetates, ethane-1-hydroxyl-1,1-diphosphonates and their sodium and potassium salts. Preferably such detergent compositions are particulate, either flowable powders or aggregates or briquettes. It is desirable to take precautions to minimise contact between the bleaching agents and between them and other components of the detergent composition, which is achieved by pelletising or granulating the bleaching agents individually, together, or in admixture with an inert substance on one which has a stabilising effect. Alternatively the bleaching agents, individually or together, or in admixture with inert protective material which is removed by solution, melting or abrasion in the washing process. In conventional type heavy duty household detergents the available oxygen is normally in the range 0.1 to 3% by weight of the composition and especially 0.25 to 1%.

Title: Reducing scouring around legs of marine structures
IPC: E02B17/02
Filed: 1968-12-31
Abstract: 1,200,280. Reducing scouring round legs of marine structures. MOBIL OIL CORP. 31 Dec., 1968 [13 March, 1968], No. 61845/68. Heading E1H. In a marine structure comprising a platform 12 having legs 13 which can be extended to rest upon a marine bottom 17 and support the platform above the water, each leg has a support 25 for anti-scouring material 31 placed thereon before the leg is extended and means on the support to displace the material when the leg is extended and positioned on the marine bottom, the material then aleviating scouring about the legs. As shown on the leg 13 on the left side of Fig. 1 the support 25 is attached to cross bracing 21 on the leg. The support comprises a pallet on which a flexible, extendable member, e.g. of nylon or wire net, or of cloth, canvas or plastics, rests and on which the ante-scouring material, e.g. sandbags 31, is placed. As shown on the leg 13 on the right hand of the Fig, the extendable member 29 is pyramidal with a rope or cable 30 secured at its apex 29 so that a pull on the rope or cable raises the flattened member 29 supporting the material 31 to its extended positioned so that the material 31 falls downward around the foot 23 of the leg.

Title: Facsimile copier with controlled reproduction scale
IPC: G03F1/00
Filed: 1978-06-06
Abstract: A facsimile copier in which an original pattern may be reproduced in a modified scale i.e. enlarged or reduced, but with the same aspect ratio, comprises rolls (1,2) supporting the original and copy respectively and intermittently driven one step after each line scan of a scanning head (SH) and copying head (CH) across the width of the original and copy. The heads are driven along a track (5), their scanning direction being reversed after each line scan simultaneously with the original and copy being moved one line width. The original and copy are thus scanned with a reciprocating line scan pattern. The scanning speed of the heads and the displacement of the original and copy are adjustable to obtain the desired modified scale. An adjustable belt-pulley-clutch drive arrangement is described. The video signal from the scanning head may be stored on a magnetic tape or disc together with scanning control signals for later use with a second copier. The copying head may be electrostatic or electro-dynamic e.g. an ink-writer, and preferably is controlled to mark the copy only at points corresponding to the leading and trailing edges of each feature in the original. To reduce reproduction time the scanning heads may have a dual speed control. The application described is the lay-planning of garment pattern pieces. <IMAGE>

Title: Semiconductor device
IPC: H01L29/8605
Filed: 1978-06-29
Abstract: A P-conductivity type resistor layer 12 is formed in the main surface of a silicon substrate 11, and extends along a crystal axis of [001] where the main surface is a crystal face of (110), or else it extends along a [010] or [001] axis in the case of a (100) face main surface. It has been found that the resistance value of a P-conductivity type resistor layer of such orientation is less affected than other orientations in the same plane by the thermal stresses induced in the layer by the shrinkage of a plastics resin envelope 18 during the moulding thereof. <IMAGE>

Title: Signal-envelope display system for a digital oscilloscope
IPC: G01R13/34
Filed: 1980-08-28
Abstract: A signal-envelope display system for a digital sampling oscilloscope includes a digital memory (16) for storing minimum and maximum signal values measured over a short interval, in adjacent storage locations, an address counter (18) for sequentially addressing the memory, and a control circuit for selecting via switch (22) the least significant bit of the address count signal arriving at the memory. This bit is allowed to alternate high-low to select every location of the memory, or is held high or low to select only the even or only the odd locations. The values retrieved from memory are then converted to analog (24) and a vector generator (26) connects them to provide connected minima and maxima to shade in the waveform, connected maxima, and connected minima to outline upper and lower edges. A full signal- envelope display is provided by superposing the three displays, showing for example a modulated carrier. <IMAGE>

Title: Improvements relating to friction pad assemblies for use in disc brakes
IPC: F16D65/097
Filed: 1982-01-08
Abstract: This specification discloses a friction pad assembly for use in a disc brake and having pad anti-rattle spring with a coiled region (17) intermediate its ends, the coils being axially spaced apart from each other and engaging in a slot in the backing plate, the slot and spring presenting planar surfaces (13, 27) which can interengage with each other. Thus, by virtue of the interengaging planar surfaces (13, 17) the coiled region (17) can only rotate in the slot (7) at most to a limited degree, and should a spring arm (19) be broken, the other spring arm (19) can continue to function. Also, the location of the coiled region (17) in the slot is space saving and the spaced apart coils allows the maximum spring performance to be achieved. <IMAGE>
