Patent GB-374033-A (GB)
Title: Improvements in or relating to grinding or polishing tools
IPC: B24D3/28
Filed: 1931-02-27
Abstract: A process for the manufacture of grinding and polishing tools comprising an abradent filler and a phenol-aldehyde resin binder, consists in producing the binder by the conversion of a phenol-aldehyde resin in the A state dissolved in a B-resin solvent into the B state while so dissolved.  The conversion into the B-resin may be effected either before or after the solution is applied to the grains.  The initial condensation into the A-resin may also be effected after the solvent and resin ingredients are mixed with the grains.  Suitable B-resin solvents are hexalin, methylhexalin, hexahydro-beta-naphthol, and furfurol.  Solvents which are only effective as B-resin solvents at elevated temperatures and pressures may also be used, such as a mixture in equal proportions of benzol and alcohol.  Liquids which are non-solvents for B-resins may also be added such as tetralin and brombenzol.  In an example, 8 kg. of a powdered phenolaldehyde resin in the A-state is mixed with 2 kg. of methylhexalin and 90 kg. of silicon carbide at a temperature of 110 DEG  C. for one hour. The mixture is moulded under pressure and heated during moulding or afterwards.

Title: Semiconductor circuits
IPC: H03K17/14
Filed: 1963-02-15
Abstract: 1,007,654. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 15, 1963 [March 1, 1962], No. 6275/63. Heading H1K. [Also in Division H3] A semi-conductor switching circuit comprises a semi-conductor wafer with three separate zones of one conductivity type contacting a zone of the opposite type and means for causing minority carrier injection from the middle one of the three zones to provide a low impedance path between the other two of the three zones. Fig. 1 shows a P- type body 20 with three rectifying contacts comprising N- type regions 22, 24 and 26 and an ohmic contact 30. The application of a forward bias between electrode 30 and region 26 by means of switch signal source 12 injects carriers to drive both portions of the device to saturation conditions whereby a low impedance exists between input electrode 22 and output electrode 24. A potential source 33 in series with a resistor 35 provides a bias potential between electrodes 22 and 24; the arrangement operates like two transistors with the switch signal source connected to the two emitters and the two base electrodes as shown in Fig. 2. Under cut-off conditions at least one of the PN junctions associated with regions 22 and 24 is reverse biased. Electrode 30 and region 26 extend over a relatively large area to provide uniform potential over the P-type region 20 and the ohmic electrode 30 may be E- or H-shaped. Fig. 3 shows a modification in which two units, as shown in Fig. 1, are combined with a common output N-type zone 160 to provide in effect a single pole doublethrow switch. Switching may alternatively be effected by electron bombardment of the N- type zone 26 and for this purpose an electron beam may be arranged to scan a plurality of devices of the type shown in Fig. 1. The semiconductor material may consist of silicon, germanium, compounds of gallium, aluminium or indium with arsenic, phosphorus or antimony, silicon carbide or cadmium sulphide, and the structure may be produced by alloying, diffusion or epitaxial deposition. In one example, gold-boron and gold-antimony foils are alloyed to a wafer of P-type silicon containing boron. Specifications 889,058 and 913,674 are referred to.

Abstract: 199,097. British United Shoe Machinery Co., Ltd., and Gouldbourn, J. March 13, 1922. Pulling-over and lasting.-A pulling-over or pulling-over and lasting machine is provided with means which, to deal with differing shoes, automatically and positively drives into different operative positions an element or elements, such as wiping and tacking means. which operate on the margin of the upper. The element is connected to two driving devices in series, the second being yielding. The side clamps 5, 9 described in Specification 9385/10 are connected by a link 16, pivoted arm 17 and link 19 with a slide 20, so that when the clamps are swung into contact with the shoe their position determines that of a cam surface 28 on the slide 20. The slide 20 moves in a way 21 formed on the plunger housing of the slide which moves the tacker arm 2 inward, as described in Specification 7005/00. Perpendicular to the way 21 is a way 23 in which slides a locking piece 24. The construction is such that as a face 29 carried by the tacker arm contacts with a stop 10 on the side clamps, the cam 28 lifts the locking piece 24 and brings an opening 26 therein into alignment with the plunger pin 27, Fig. 3. The plunger is then free to yield if necessary, so that no further movement of the arm 2 takes place. The clamp 5 is provided with serrated adjusting means. The wiper 1 has a hemispherical boss 3 engaging a corresponding cupped seat, so that it can yield universally against its spring 4. Specification 12304/03 also is referred to.

Abstract: 570,375. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd., and BARWICK, E. C. May 12, 1943, No. 7539. [Class 38 (ii)] In an induction regulator particularly suitable for controlling A.C. commutator motors, wherein a variable voltage component in quadrature relation to a constant voltage component is required, the primary and secondary windings are both wound on the stator 1 (or rotor) which has twice as many slots as the co-operating rotor 5 (or stator) and the secondary winding 4, Fig. 2b, has coils such as a, b of the same phase wound about adjacent teeth and in opposition. For the arrangement shown, the coil a is wound on a tooth that is opposite a tooth on the rotor and so is subject to a large flux and has a large induced voltage OA, Fig. 3. The coil h is on a tooth opposite a slot and so has a small voltage AB. The resultant voltage is OB which has a constant component OD and a component DB which would decrease to zero and then increase in the other direction to DB if the rotor were to move through the space of one stator tooth. In a modification, Figs. 4, 5 (not shown), the secondary winding has three coils per phase on three consecutive teeth with the centre coil connected in opposition to the other two coils. With this arrangement the constant voltage component can be made zero or of other desired value by suitably selecting the number of turns on the coils.
