Title: Improvements in or relating to circular knitting frames with radially disposed needles
IPC: D04B13/02
Filed: 1920-07-06
Abstract: 147,059. Haaga, E. June 3, 1919, [Convention date]. Circular machines. - Difficulties met with in connexion with loop formation on circular frames are overcome bv the provision of two sets of sinkers which are operated independently and not simultaneously. The loops are sunk by sinkers 13, which are mounted in a sinker-wheel, while the sinkers 1, which are mounted round the cylinder 2 like jacks, without resting on the lower flange, perform the landing, knocking-over, locking-in, and holding-down operations and prevent the loops from springing back before being pressed. Cams 9, 11, 16, 17 situated above the fabric act on the upper ends of the sinkers to impart a simultaneous upward and outward movement. Their lower ends are held in position by a spring 4 which rests in notches 3 the lower sides of which may be cut away at 15 to allow the sinkers to move upwards on the cam 16. The sinkers 1 assisted by springs &c. hold the finished loops continuously until the next loop-forming operation takes place.

Abstract: 1388433 Crosslinkable polymers containing urethane groups BAYER AG 25 April 1972 [30 April 1971] 19136/72 Headings C3P and C3R Polymers which are crosslinkable by vinyl polymerization contain per molecule at least two groups of the formula where R is H or C 1 -C 4  alkyl and n is an integer from 1 to 6. The polymers may be prepared by reacting a polymer containing hydroxyl groups with a monomer of the formula where R and n are as defined above. In examples the hydroxyl-containing polymers are (1) a hydroxypropyl methacrylate/methyl methacrylate/methyl acrylate copolymer; (2) as in (1) except that the acrylate component is n-butyl acrylate; and (5) a polyester derived from phthalic acid and trimethylolpropane. Vinyl alcohol polymers are also useful. The polymers of the invention are useful in the production of coatings which can be crosslinked by heat or actinic radiation, optionally in the presence of a free radical initiator.

Abstract: 278,998. Bronander, W. B. July 1, 1926. Cylinders receiving liquid fuel.-In an engine of the kind having a pair of inter-communicating cylinders with pistons 33, 34, which move in the same direction for the greater part of their strokes but out of step, the valve of a fuel injector 50 is opened by the piston 33 when the piston 34 is not at the end of its stroke.

Filed: 1961-06-02
Abstract: 964,178. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 2, 1961 [June 7, 1960], No. 19981/61. Drawings to Specification. Heading H1K. In a method of manufacturing a semiconductive device, a body of gallium arsenide having at least one asymmetrically conductive junction and provided with at least one electrode is subjected to an electrolytic etching treatment in an alkaline bath, the electrode or at least one of the electrodes being used to apply a voltage to the body positive with respect to the etching bath. The etching liquid may comprise an aqueous solution of sodium hydroxide, potassium hydroxide, a mixture of the two, or 30% aqueous ammonia. A highspeed switching alloy diode may be produced by providing a P-type gallium arsenide wafer with an ohmic electrode produced by alloying an indium pellet to the wafer in a hydrogen atmosphere at 550% using ammonium bifluoride as a flux, and with a rectifying contact by similarly alloying a gold/tin/arsenic alloy bead to the opposite surface of the wafer at 500 C. Nickel leads are joined to the electrodes and the device immersed in a 40% potassium hydroxide solution, either one or both of the leads being connected to the positive side of a power supply and the circuit completed through a platinum cathode immersed in the solution. Etching takes place around the PN junction and a shallow groove is etched under the rectifying electrode thus limiting the area of the PN junction, the rate and degree of etching being dependent only on the electrolytic current. A tunnel diode may be produced in a similar way from a heavily zinc-doped body, but in this case uniform etching occurs over most of the body because of its low resistivity although preferential etching still occurs around the PN junction.
