Title: Improvements in pulse signal delay arrangements
Inventor: ASKEW GERALD HAMILTON
IPC: H03K5/13
Filed: 1963-05-30
Abstract: 1,010,135. Transistor pulse delaying circuits. RANK-BUSH MURPHY Ltd. June 1, 1964 [May 30, 1963], No. 21662/63. Heading H3T. In a pulse delaying circuit, pulses at 1 (Fig. 1) are delayed at 8 and used to gate input pulses at 9 so as to provide a set input for a bi-stable circuit 11, the delayed pulses from 8 also being used to gate inverted input pulses at 10 so as to provide a reset input for the bi-stable circuit 11. As described, input pulses A (Fig. 2) at 1 are fed via a phase splitter 2 giving waveforms B, C which are differentiated at 3, 4 giving waveforms D, E, the combination F of which is fed via an auxiliary gate 7 to a mono-stable delaying circuit 8 which provides a negative pulse G following each pulse F, i.e. at twice the frequency of the input wave A. Waveform G is used to gate portions of the normal and inverted input waves B, C giving waves K, L, respectively used to set and reset a bi-stable multivibrator 11 giving waveform M, the onset and offset of which are respectively delayed by a time T from the corresponding transitions of the input waveform A. An auxiliary gate 7 is included to prevent spurious operation by unwanted transients (Fig. 3, not shown). A typical complete circuit is shown in Fig. 4. Monostable circuits.-The normal and inverse input waves are differentiated at 42, 45 and the resulting negative pulses used to turn on transistor 49 which discharges capacitor 51. This capacitor charges negatively at a rate determined by resistors 52, 53 until transistor 54 of a long-tailed pair becomes conductive, turning off transistor 55 and feeding a pulse to transistor 63; commencing at the time when transistor 54 is turned on and terminated by the next differentiated pulse via diode 44 or 47. NPN transistor 94 is conducting during the unstable or timing period, turning on PNP transistor 93 so as to short circuit the input to transistor 69 and prevent spurious operation by transient input signals. Gated bi-stable circuits.-Transistor 63 is connected in the common emitter circuit of the long-tailed pair of transistors 66, 67. The bi-stable circuit comprising transistors 84, 85 is thus set only on coincidence of negative pulses at the bases of transistors 63 and 66 and reset by coincidence of negative pulses at the bases of transistors 63 and 67. Specification 787,956 is referred to.

Title: Improvements in or relating to the production of semi-conductor material
IPC: H01L21/00
Filed: 1959-06-24
Abstract: 877,469. Semi-conductor devices. SIEMENS & HALSKE A.G. June 24, 1959 [June 25, 1958], No. 21686/59. Drawings to Specification. Class 37. In a method for the production of semiconductor diodes, a semi-conductor body is doped with donors or acceptors wherein a substance capable of producing recombination centres is introduced into or deposited on the body and wherein the body is tempered with materials forming recombination centres until it is saturated with such centres and then rapidly quenched. It is stated that the quenching reduces further mobility of the centres thus preventing the centres becoming ineffective and thereby obtaining a high density of such centres in order to obtain an extremely short life for the minority carriers. Examples are given of the treatment of a semi-conductor body of germanium doped with arsenic and in the form of a thin disc provided on either or both faces or its whole surface with a coating of nickel, the tempering being carried out at 760‹ C. and 810‹ C. Specific concentrations of materials are stated.

Abstract: 737,959. Motor vehicle steering gear. PAUTRAT, L. O. L. Aug. 7, 1953 [Aug. 25, 1952], No. 21828/53. Classes 79(3) and 79(5). [Also in Group XXXVII] In a vehicle steering system the steering column is formed by two normally aligned portions 3, 4 articulated together, the upper portion 3 carrying a steering wheel 1 and being connected to the vehicle by a shock absorber adapted under the impact of the driver's body on the steering wheel to yield in a continuously resisting manner. The object of the invention is to minimize injuries to drivers in vehicle crashes. As shewn in Fig. 1, the portions 3, 4 are interconnected by a universal joint 6, the portion 4 being mounted in a bearing 13 carried by a bracket 7. The portion 3 passes through a hole 11 in a rubber block 9, the hole aligning with a split in the block so that under the driver's impact the portion 3 moves up into the split. In another embodiment, Fig. 3, the rubber block is replaced by a spring shock absorber 17 connected to the portion 3 by a rod 16. Movement of the portion 3 under impact causes the ignition circuit to be interrupted. An antitheft device may be combined with the apparatus in the form of a device separating the portions of the column with locking means interposed. The dashboard ahead of the steering column may include a rubber plate permitting a greater angle of movement of the steering column and the shock absorber may be in the form of a hydraulic dash-pot or leaf- or coil-spring means.

In a froth flotation apparatus gas and liquid are delivered to the eye of an impeller through separate pipes, the pipe for the gas being connected to the liquid feeder tank at the level of the liquid surface. As shown, slurry is delivered to the eye of the impeller 12 by a pipe 9 and air by a pipe 14. The slurry is delivered from a tank 15 in which an approximately constant level 20 is maintained by flow over a weir 18. The air supply pipe 14 is also connected to tank 15 at the level 20 so that more slurry or more air is delivered to the impeller 12 according to the level 20 of the slurry surface, thus controlling fluctuations in level. Froth is discharged from the tank 1 by a rotating skimmer 4 into a trough 5, and liquid through a pipe 8. In modifications (see Figs. 3-8, not shown), the end of the pipe 14 may be arranged in the tank 15 as a standpipe, which may be surrounded by a bell the edge of which may be oblique or have a notch therein; the bell may be adjustable. Alternatively the end of the pipe 14 may be a downpipe in the tank 15 with an oblique edge at the level 20.

Title: Improved manufacture of seed disinfectants and their application
Filed: 1932-08-05
Abstract: Dry seed disinfectants, such as phenyl or tolyl mercuri actate mixed with a diluent such as talc, are treated, to prevent dust rising in use, by incorporating therewith a solid fatty or waxy body dissolved in a solvent and then removing the solvent by evaporation.  In a modified process the diluent and the fatty or waxy body may be added to the solvent, such as toluene, in which the mercury compound has been prepared but from which it has not been isolated.  Pigments such as iron oxide may also be added. Mineral wax or jelly, hydrogenated oils, beeswax, stearic acid and various other substances are given as examples of suitable fatty or waxy bodies.  Incorporation of fatty or waxy bodies with dry seed disinfectants by grinding or by adding them in the form of emulsions is stated to be unsatisfactory. Specification 241,568, [Class 81 (i), Disinfecting &c.], is referred to.

Abstract: 856,488. Glass manufacture, enamels and enamalling. GENERAL ELECTRIC CO. Ltd. May 20, 1959 [July 11, 1958], No. 22303/58. Class 56. The process of applying to the internal surface of a cylindrical tube of a fusi glass, a layer of a second glass of lower melting temperature includes the steps of coating the internal surface with a powdered second glass or enamel in a volatile suspending medium, heating the tube to remove the volatile constituents, rotating the tube while applying to the external surface at regions spaced apart along the length of the tube sufficient localised heat to fuse the powdered coating in circumferential regions of the tube and varying the regions of application of the heat axially along the tube until the whole of the powdered coating is fused, the heating, the width and spacing thereof and the rate of axial variation being such that the parts of the tube between the heated parts at any time remain sufficiently rigid to maintain the shape of the tube. The tube 1 is rotated and heated by resting a pair of rotating steel rollers 2, 3, heated from below by gas flames 4 and a current of air, passed through the tube to carry off the volatile constituents. A row of fine painted gas flames 5 are then lit, the flames being about half an inch apart and heating a zone 6 about 4 mm. wide. At intervals of about one minute the flames 5 are moved along the axis of the tube by about 4 mm. until the whole coating is fused. The process may be repeated several times to give a final inner coating of about 0.03 mm. thickness.
