Abstract: 894,672. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 27, 1958, No. 20704/58. Drawings to Specification. Class 37. A wire, at least the envelope of which is aluminium, and which is coated with a layer of oxide of sufficient thickness to enable fusion of the aluminium to take place without breakage of the oxide layer, is fused to a semi-conductor material. The oxide layer should have a thickness of from 3 to 40 microns and the semiconductor material and the material inside the aluminium envelope of the wire may be germanium or silicon, and tin may be used to connect the semi-conductor device to a base-plate. The device may be a diode or a transistor and in one embodiment (Fig. 3, not shown) it may be sealed inside an evacuated casing. A device according to the invention may be constructed by degreasing an aluminium wire by washing in caustic soda solution, nitric acid and then water and then oxidizing the surface either by dipping in a solution of H3PO3, CrO3, NH4HF2, and (NH4)2HPO3 in water or by subjecting the wire to anodic treatment at 60 volts D.C. in a solution of oxalic acid in water. The end of the wire may then be cut and polished and held in contact with a silicon body by means of a graphite jig (Fig. 2, not shown), while the whole device is heated in an oven to cause fusion to occur. Copper wire or cable may then be spotwelded to the aluminium wire at a point some distance away from the semi-conductive body.

That part of the collector region 1 of a transistor adjacent to and extending into a recess in the base region 6 immediately opposite the emitter region 8 has a lower resistivity than the rest of the collector region, thus reducing the collector capacity. The low resistivity part 4 is obtained by initially diffusing into a chip of semi-conductor material of the required conductivity type for the collector an impurity of this same conductivity type, to a depth just greater than that to which the base will be diffused, prior to the steps of diffusing the base 6 and emitter 8. The conductivity of the low resistivity area is at least five times greater than that of .the remainder of the collector region. This method also prevents the bulging of the base region due to emitter dip effect.

Abstract: 1,257,738. Abrasive wheels. MERIT PRODUCTS Inc. 15 April, 1969 [14 May, 1968], No. 19211/69. Heading B3D. An abrader for an abrasive drum comprises abrasive means and means for securing the abrasive means to a core of the drum, the securing means being adapted to extend into a peripheral recess in the core and releasably engage radially inwardly facing shoulders in the core. The core 40, Figs. 1 and 3, is of rigid material formed with a plurality of helically arranged slots 46 of substantially keyhole shape having a narrow entrance 48 and inwardly disposed shoulders 50. The core may be constructed from a single piece of material or a plurality of discs each formed with recesses, the discs being staggered to form helically-stepped recesses which may be machined to form smooth helices. The abrader 42, Figs. 1 and 9, consists of a pack of abrasive leaves secured to the wing 55 of securing means 52 having a rodlike portion 54 for engaging a recess 46 in the core. The abrader is helically formed and the rod-like portion may be flexible and formed of a plurality of short lengths to assist engagement with the recesses or be pre-formed to a helical shape. When the securing means is in a number of short lengths, a cable may extend through the hollow rod-like portions. In another embodiment, the slots in the core have a dove-tail crosssection. A securing means 105, Fig. 23, of dovetail shape may be held on the arms 106 of a jig in a helical shape while an adhesive securing the abrasive leaves thereto sets. In a further embodiment, the slots 124, Fig. 24, in the core are straight but at an angle to the axis of the core which thereby has a smaller diameter at its centre than at its ends. The securing means on the abraders are thus straight and the abrasive leaves 120, Fig. 27, may be shaped as shown to compensate for the smaller diameter of the core at its centre so that the assembled drum is of cylindrical configuration. In another arrangement, the core 130, Fig. 24, consists of two series of alternate discs separated by peripheral recesses, one series having keyhole shaped slots 135 and the other series U- shaped slots 138. An abrader comprising a helically formed pack of abrasive leaves 140, Fig. 34, is secured to a central fin 144 which engages the keyhole slots in one series of discs and to a U-shaped loop 148 which engages the U-shaped slots 138 in the other series of discs, the abrader being presented radially to the discs as distinct from axially as in the previously described embodiments. A rod 146 secures the abrader to the drum. In yet another embodiment, the core consists of a number of spaced circumferential ribs defining intervening grooves, each of the ribs having a series of circumferentially spaced circular apertures, the apertures in the ribs being arranged in helical rows. The abraders comprise packs of abrasive leaves secured to U-shaped loops which are engaged in the grooves and by rods passing through the apertures.

Abstract: 1,266,541. Numerical control of machine tools. ALLEN-BRADLEY CO. April 14, 1969 [May 2, 1968], No.18987/69. Heading G3N. A system for numerically controlling the movement of a machine tool from a first to a second position includes, for each co-ordinate axis, a plurality of command counters and an equal plurality of feedback counters. The contents of the counters are compared to generate a signal to control the tool motion. When a desired position is fed as a numerical word into the command counters, these counters are continuously advanced at a clock rate while the feedback counters are advanced at a different rate dependent on the movement of the tool until the counts match. The use of more than one counter, and preferably a number of counters, each of equal capacity, all of which are filled simultaneously, enables a much shorter sampling time to be used compared with a system having only a single counter on each axis. Data input may be devised from paper tape, and includes feedrate data. The feedrate is controlled by the distance of the tool from the final desired position.
