Title: Improvements in lock-nuts
IPC: F16L19/00
Filed: 1962-11-30
Abstract: 987,717. Locking nuts; pipe joints; wire &c. Strainers. FIBORA A.G., and W. ENGELMANN. Nov. 30, 1962 [Dec. 6, 1961; April 17, 1962], No. 45366/62. Headings F2G and F2H. [Also in Division B4] A lock nut 1, for use on bolts, pipes or turnbuckles, has a reduced neck end divided into segments 3 which, after tightening of the nut and by the non-rotary action of a clamp and without further rotation of the nut or bolt &c. are all compressed radially inward to grip the bolt &c. The clamp may be a simple loop of wire 24, Fig. 9, in a groove 21 on the segments 3, with the ends 25 twisted together, in which case there may be transverse slots 26 at the bases of the segments to give them extra resilience. The wire may be replaced by an open ring with a loop and lever connecting the ends and tightened by the lever, Fig. 11 (not shown). The outer surfaces of the segments 3 may form a cone 4, Fig. 3, so that the segments are compressed by axial movement of a closed ring 5 (with a conical inner surface) by levering with screwdrivers or wedge-ended pliers, Figs. 15, 16 (not shown). This form is shown applied to the joining of a pipe to another pipe, Fig. 12 (not shown), or to a tank, Fig. 13 (not shown), or applied to a turnbuckle, Fig. 14 (not shown). The conical surfaces may be grooved to prevent loosening of the ring 5 which may have an external flange at the top, Fig. 1 (not shown); the loosening may be prevented by a cap 7 with tabs, on a rim 8, bent in beneath the ring 5, or the rim may extend to be bent in at least in parts. The ring hole may be small enough to give slight initial tension to the segments 3 before tightening the nut 1. Instead of the thick ring 5, a closed sheet metal band, Fig. 4 (not shown), of conical form may embrace the segments 3. The band is raised axially by pliers with pins for engaging diametrically opposed holes in the band. Tabs at the top of the band are then bent over the tops of the segments 3. The ring 5 or the conical band may be kept raised by wire or a spring ring between it and the nut body. In a form in which the neck formed by the segments 3 is cylindrical or tapered up to a bead end, a clip like a hose clip, with ends drawn together by a screw, compresses the segments or a clip 13, Fig. 6, is tightened by a C-slide 15 pushed down over the inclined ends 14 of the turned-back end portions of the clip band. A tab 17 on the band may be bent over the slide 15, or the latter may have a tab to be bent under the band, to hold the slide on. In Fig. 7 a wire ring 18 open or in halves is located in a groove 21 around the segments 3 and the pair or each pair of turnedback ends 19 is held in an elongated hole in a stirrup 20, so that lowering of the stirrup to one side draws the ends together to tighten the ring 18 and segments 3.

Title: Surface diffused semiconductor devices
Inventor: BROWN DALE MARIUS
IPC: H01L21/331
Filed: 1968-09-27
Abstract: 1,245,765. Semi-conductor devices. GENERAL ELECTRIC CO. 27 Sept., 1968 [13 Oct., 1967], No. 46115/68. Heading H1K. Surface channelling under passivation on a region is prevented by applying a fixed potential opposite in sign to the majority carriers of the region to a capacitative electrode buried in the passivation. The technique is applied to a planar junction, the buried electrode being formed only over that region in which inversion would occur and terminating substantially coextensively with the junction. One embodiment is in the form of a PNP transistor: the buried electrode covers the surface of the collector region and is used during processing (together with the underlying insulation) as a diffusion masking in the formation of the base region. Emitter and base metallization tracks are later applied over the insulation above the buried electrode, capacitance between these and the substrate (collector) being low since the buried electrode is operated at a fixed potential. In a modification the buried electrode is formed in two concentric portions, the gap between them being used as a diffusion aperture for the formation in the collector region of a heavily doped guard ring at the same time as the emitter is diffused. In variants of these, the thicknesses of the buried electrode and its underlying insulation are made so small that during emitter diffusion some impurity can reach the collector region to enhance the conductivity of its surface. A further embodiment is a lateral transistor with concentric emitter and collector planar regions. That part of the base region exposed in the annular gap is covered with passivation containing the buried electrode extending over the whole area.

The discs are made by forging a heated billet or ingot into a solid disc forging the disc into a basic wheel shape, piercing a hole through the disc centre, roll forging the outer rims, and press forging to final shape. Alternatively the discs may be cast. The central bores 62 are machined and a pair of discs is mounted on a pilot shaft for subsequent machining. The discs may be additionally welded at their hubs and they may be joined by friction welding. In an alternative embodiment, Fig. 3 (not shown), hub portions (36<SP>11</SP>) are welded to a length of steel tubing (72) thereby avoiding making an inside weld. The discs are shaped on rotatable forging dies (64) and are provided with apertures (66) to receive pilot drive pins (68) which locate the discs and provide a drive force. An extra tool works the outer periphery of rim sections (12<SP>11</SP>) to form radial flanges (70) and the discs are dished by press forging. The wheel is used as a track idler wheel for earth working vehicles.

Abstract: 1,071,268. Photo-electric guidance systems. OFFICINE GALILEO S.p.A. Dec. 2, 1963 [Dec. 11, 1962], No. 47398/63. Heading H4D. A vehicle is guided by directing an optical radiator beam to a receiver in the vehicle, part of the beam is modulated alternately at a frequency F 1  and a frequency F 2 , the whole beam is amplitude modulated at a reference frequency # 0  and the receiver compares outputs at frequencies F 1  and F 2  and at frequencies F 1  and # 0  to afford control signals which tend to maintain the vehicle on a fixed path with respect to the beam. The embodiment relates to the guidance of a missile by a beam from the ground, frequency F 2  being F 1/2  hereafter termed f. The modulation at frequencies f, 2f is effected by a rotating reticle carrying two series of radial slits one series having twice the number of slits as the other (Fig. 2, not shown); at the receiver the outputs at the two frequencies are compared after amplitude equalization and rectification to give a radial-error signal. The reference signal is produced by a disc which is half transparent and half attenvating, the disc being rotated at a predetermined rate with respect to that of the reticle; at the receiver the reference signal phase is compared with that of the signal of frequency 2f after rectification of the latter to give an angular-error signal. The missile is stabilized against rotation about its own longitudinal axis. Optical and electric frequency filters may be added.

Abstract: 1,079,260. Transistor testing. AMERICAN ELECTRONIC LABORATORIES Inc. Nov. 24, 1964, No. 47734/64. Heading G1U. The beta parameter (Ic/Ib) of a transistor 15 is measured by means of a meter 7 switchable between the base and collector circuits. The transistor is arranged in a common base circuit operating under Class B conditions, with a collector current below its saturation value. When the meter 7 is switched into the collector circuit, a resistor 24 is arranged in shunt with it, and the output from generator 2 is adjusted to give full scale deflection reading on the shunted meter. Switch 6 is then operated to the "beta read" position connecting the meter in the base circuit without a shunt and shorting resistor 24. The base current indicated is then a direct measure of beta. Errors are discussed and a correction curve deduced Fig. 5 (not shown).
