Abstract: 1402007 Vacuum work-holders INTERNATIONAL BUSINESS MACHINES CORP 5 Oct 1972 [21 Oct 1971] 45908/72 Heading B3D [Also in Division F2] A vacuum work-holder comprises a workpiece retaining surface 11 having a plurality of vacuum ports, 13A-13G, and fluidic control means 17A-17G coupled to the ports and to a vacuum source 16 for sensing which ports are covered by a workpiece 12 and for selectively connecting those ports covered by the workpiece to the vacuum source and preventing coupling of the source to those ports not covered by the workpiece. The work-holder may be used for holding semi-conductor wafers for dicing, inspection or testing and has a body 10 formed with the ports 13A-13G in its surface 11, each port being connected by a respective passage 14A-14G and lines 18A-18G to a respective logic circuit 17A-17G. Each logic circuit is connected to the source of vacuum 16 and a pressure supply 22 and consists of a housing 40 formed with chambers 41, 42 having diaphragms 43, 44 interconnected by a rod assembly 45. The port 46 connects the pressure supply to chamber 41, the vacuum source is connected to a port 47, and a port 49 is connected to line 18 which leads to the chuck and is connected by a feedback line 35 and port 48 to the chamber 42. The vacuum source and a pulse of pressure are connected simultaneously to ports 46, 47. The pressure pulse in chamber 41 moves the diaphragms 43,44 to the right so that the vacuum is connected from port 47 through ducts 51, 52, 53 to port 39 and the respective port 13 in the chuck. If the workpiece covers the port, the vacuum applied through feedback line 35 to chamber 42 holds the diaphragms so that the vacuum is maintained connected to the respective port 13. If the port is not covered by the workpiece, the drop in vacuum in chamber 42 permits the diaphragm 44 to close the flow through ducts 51, 52. A further port 50 may be connected to a pressure source to act as a release for the circuit or may be used as part of a feedback circuit.

Title: Hair setting

Filed: 1973-10-02
Abstract: 1429086 Hair setting PROCTER & GAMBLE CO 2 Oct 1973 [2 Oct 1972] 45974/ 73 Heading D1P A process for deforming hair comprises wetting the hair with an aqueous solution from 1% to 20% by weight of an alkali metal monopersulphate oxidant, at a pH of not less than 5, subjecting the moist treated hair to a longitudinal stress, and thereafter drying the hair in the stressed configuration. The longitudinal stress may be achieved by winding the wet hair on a mandrel (e.g. a spiral rod or a Croquignole curler), by winding the hair loosely into pin curls, or by forming it into a straight configuration, e.g. by brushing. Preferably the hair is in contact with the oxidant for 1-30 minutes, after which the latter is removed by rinsing with water-preferably deionised water to prevent a build up of Ca and Mg ions on the hair-or by shampooing. The hair-deforming compositions, which may comprise separately packaged portions of oxidant and a shampoo composition comprising a non- cationic surfactant and water, preferably have a pH in the range of 7.0 to 9.5 and which may be maintained by a buffer. The preferred buffer comprises 0.5 to 10% by weight each of sodium bicarbonate and sodium carbonate. Further components of the composition comprise thickeners, e.g. carboxymethyl cellulose, high molecular weight polyoxyethylenes, MgAl silicate and silica gel. The process may be carried out at room temperature or elevated temperatures up to 150F, and does not substantially bleach the hair.

The tool 30 contains a piston 51 carrying a bore cleaning tool 60 and a plate 49. Before the seat 17 reaches the recess 23, a ball 70 is dropped down the string M to close the central bore of the piston. Hydraulic pressure in the pipe string M can then be used to depress the piston so that the plate 49 presses on the seat to shear the holding screws. The seat can then be pushed to the recess 23.

Abstract: 1,261,604. Welding by pressure. SUMITOMO KINZOKU KOGYO K.K. 23 Sept., 1969 [25 Sept., 1968], No. 46823/69. Heading B3R. In butt welding steel bars of at least 30 mm. diameter the bars are pressed together while being heated to welding temperature with a hydrocarbon-oxygen flame sufficiently reducing to deposit carbon on the faces of gaps between the otherwise abutting steel bars, the reducing frame is switched to become neutral and the pressure is continued at a lower level. Steel bars while abutted under pressure of e.g. 530- 650 kg./cm.<SP>2</SP> are heated by an oxygen-acetylene flame, the flow rate of acetylene to oxygen in the burner being in the range of 1À3 : 1 to 2À0 : 1 preferably 1À5 : 1 to 1À7 : 1 to a temperature of about 1200‹ C. and a carbon film formed by incomplete combustion of acetylene is deposited on the bars. During heating the burner is oscillated to and fro axially to ensure uniform heating. When welding temperature is reached the flame is changed to become neutral to cause the deposited carbon to become diffused into the steel and the pressure is reduced to 180- 280 kg./cm.<SP>2</SP>. The pressure applied while the parts are heated with the reducing flame may vary. In an example two 50 mm. diameter steel bars (0À24% C, 0À15% Si, 0À23% Mn) are heated by a ring burner supplied with acetylene and oxygen in the ratio of 1À6 : 1 and are pressed together at 550 kg./cm.<SP>2</SP>. After heating for 2 minutes the flame is made neutral and pressure is reduced to 250 kg./cm.<SP>2</SP>. In other examples bars of 41 mm. diameter and 50 mm. diameter are welded using the same burner, with an acetylene : oxygen ratio of 1À7 : 1. Instead of acetylene-oxygen flame a propane-oxygen flame may be used.

Abstract: 1452964 Forming bonded yarns HOLLANDSE SIGNAALAPPARATEN BV 12 Oct 1973 [19 Oct 1972] 47897/73 Headings DIF and D1W In the manufacture of bonded yarn, an initial fibre ribbon which includes a fibre component for effecting the bonding is drafted to thinner form which is then brought into contact with a heated surface for a period sufficient to complete activation of the bonding component and to dry the ribbon. The drafted ribbon may be false-twisted (if yarn having little or no twist is to be formed) and wetted and/or preheated (to initiate activation of the bonding fibre) e.g. by hot water, before contacting the heated surface. The final yarn may be formed by "open end" spining and "self-twist" methods. The bonding fibre may be expandable, gelatinisable or soluble in water e.g. unstabilised polyvinyl alcohol or alginate fibres, or soluble in mixtures of water and solvents e.g. acetone, formic acid, acetic acid, such as di- and tri-acetate fibres, or meltable fibres such as polyamides or polyolefines (melting under a relatively low temperature). As shown: a prepared roving 1 (which contains the fibre bonding component) drawn from package 2 passes around guides 3 to serrated and rubber, back and front drafting rollers 4, 5, and 6, 7.
