Abstract: 1,197,670. Sewing machines. AMERICAN MACHINE & FOUNDRY CO. 17 Oct., 1968 [9 Oct., 1968], No. 49219/68. Heading D1G. A sewing machine comprises a curved needle 13 and chucks 10, 11 for passing it right through work material, the machine comprising means 21 for gripping the thread whilst the trailing end of the thread is pulled through the work to prevent punching of the stitch. In operation the chuck 10 passes the needle to chucks 11 through the work and at this point the thread clamp 21 grips the thread between the first formed stitch and the needle. The thread clamp 21 then moves to pull the stitch taut. A looper 18 subsequently takes the loop 17 formed by the trailing end of the thread between the needle and the work and pulls it to a hook 20', during which movement it is also gripped by a second clamp 22. It is then hooked onto a hook 20' and finger 20 comes around to transfer the thread to the thread puller 19. Once the gripper 22 has the thread it is released by the grippers 21.

Title: Dyeing keratin with reactive dyes
Inventor: EGLI HERMANN
Filed: 1963-12-20
Abstract: Keratin containing substances especially wool are dyed using reactive dyes and a water soluble amine sulphite in aqueous solution which may be applied before, during or after the dyeing with the reactive dye. The amine sulphite is applied at temperatures of 50-110 DEG C and if applied before the dye, acids inorganic or organic or their salts are used.  On completion of the dyeing the pH of the dyebath may be adjusted to pH 7-7.5 by adding alkali, ammonia or hexamethylene tetramine or a mixture of salts as a buffer.  The water soluble amine sulphites are for example those of substituted or unsubstituted mono, di, or tri alkyl amines with 1-4 carbon atoms preferably substituted with hydroxy or amino groups especially tri-ethanolamine, ethylene diamine or diethylene triamine, also those of aromatic, araliphatic, amines and of substituted or unsubstituted mono or di cycloalkyl amines or amines which are heterocyclic and mononuclear.

Abstract: 1399163 Semi-conductor devices FERRANTI Ltd 7 Nov 1973 [8 Nov 1972] 51566/72 Heading H1K An ohmic contact 50 comprising a polycrystalline silicon layer 20 and a tungsten or molybdenum layer 21 is formed over an apertured silicon oxide passivating layer 14 on a monocrystalline silicon body 11 by consecutive deposition in the same deposition apparatus, the polycrystalline silicon being deposited from an atmosphere of silane at 700-750 C. and the metal layer 21 then being deposited by modifying the atmosphere by introducing therein a vapour of a compound of the metal which is reduced by the silane, the atmosphere being maintained at the same temperature. A second polycrystalline silicon layer 40 may be deposited over the metal layer 21 by stopping the supply of the metal compound, which may be the hexafluoride of tungsten or molybdenum, to the deposition chamber, still maintaining the temperature within the same range. The polycrystalline layers 20, 40 may be doped with a conductivity-type determining impurity, e.g. phosphorus, and may provide a resistance within the ohmic contact required for operation of the device, e.g. a transistor. The doping of the first polycrystalline layer 20 may be such that its deposition produces a P-N junction in the semiconductor body, Fig. 3 (not shown). The ohmic contact may be completed by depositing a gold or aluminium layer 41 on to the second polycrystalline layer 40 such that it forms an intermetallic compound therewith. An inert diluent of nitrogen or argon may be included within the atmospheres of the deposition apparatus. In an alternative arrangement the first polycrystalline layer may be doped by the transfer of impurity from the contiguous region of monocrystalline silicon body.

Abstract: 1,191,408. Blasting. CORNING GLASS WORKS. 31 Oct., 1968, No. 51574/68. Heading B3D. [Also in Division H1] A resistor tailoring machine comprises abrasive blast nozzles 18 controlled by valve assembly 24 (Fig. 2) and adjustably positioned to impinge on a metal oxide film resistor(s) deposited on a substrate 28 mounted on a pad 38 adjustably positioned on a table 14 which is itself movable in the perpendicular directions "X" and "Y" (Fig. 8, not shown) and conducting probes 36 which are movable together vertically to engage conductive portions (30, Fig. 7, not shown) on the substrate 28 to monitor the value of the resistance being tailored with respect to a standard set resistance (R8, Fig. 10(c), not shown). The abrasive blasts removing portions of the resistor films in a preset pattern to alter the resistance values continue till a known value is reached, switchoff being initiated early to compensate for the mechanical lag of the system. After a strip (34, Fig. 7, not shown) of the resistor 32 has been removed while the table 14 slowly moves in the direction " X", the blast stops and the nozzles rise; the probes and the table then move together under numerical control from the unit 16, exposing a new column of metallic film resistors to the abrading action of the nozzles. Controlled reciprocating movement of the probe assembly 22 (Fig. 2) is made possible by a motor (164, Fig. 6, not shown) by means of a gear drive, and other moving parts like the abrasive blast nozzles, table 14 &c. are moved by means using compressed air. Limit switches operate at the extreme ends of the linear movement of the abrading nozzles and the probe assembly. Vacuum is utilized to hold down the substrate on to the pad 38 [which is itself mounted on the table by means of fixed pins (40, 41, 42) and movable pins (44, 45, Fig. 3, not shown)] and also to extract through an inlet 68 into the manifold 66 the abrasive particles after they have been used for blasting. The unit 16 for numerical control of the operation is programmed for moving the work-table, probes and nozzle carrier precisely in a preselected pattern and the whole process may be continuous with circuitry to monitor and control the operation (Figs. 10A, 10B and 10C, not shown) and arrangements to sort the " acceptable " and " to be rejected " finished resistors.
