Patent GB-1264032-A (GB)
Title: Improvements in or relating to semiconductor devices
IPC: H01L23/485
Filed: 1969-04-03
Abstract: 1,264,032. Transistors. FUJITSU Ltd. 3 April, 1969 [4 April, 1968], No. 17672/69. Heading H1K. The planar transistor of Figs. 1 and 8 (and of Figs. 2-7, not shown) has a grid-form emitter region 3 with the apertures in the grid shown having octagonal boundaries. The base region 2 extends to the surface through these apertures. The small circles 2a, 2b, 2g, 2p etc. show areas at which contact is to be made to the base region and circles 3a, 3b, etc. show areas at which contact is to be made to the emitter region. An insulating layer 10 (of silica or silicon nitride) is formed over the surface and apertures formed in the contact areas. An overall deposit of aluminium is applied. This is etched to remove metal around the emitter contact areas and leave a grid-form base electrode 4. Aluminium may be left in the emitter contact apertures. A second insulating film 6 (of siliconmonoxide, silica, or silicon nitride) is applied to cover all except the perimeter of the base electrode and apertures produced in this to correspond with the emitter contact areas. As shown, the emitter electrode is formed by the deposition of a silicon layer 8 and by the provision of a metal layer 9 of Au, Al, Ag, Pt, Ni, Mo, Ti, or Ta. Germanium or gallium arsenide may replace the silicon, or a metal of relatively high resistivity may be used instead. This structure effectively forms a series of emitter resistors in the apertures 8a, 8b, 8c etc. and leads to even distribution of current to the various parts of the emitter region. In variants, only the material in the apertures or only the material in the main sheet 8 need be of resistive material (and parts of the sheet carrying little current may be removed). The construction may be so modified that the emitter electrode lies under the base electrode. Since the exterior surface of the electrode structure is a plane sheet, the transistor may be mounted with its emitter (or base) electrode in contact with the header of its hermetic housing to ensure efficient heat dissipation. Reference has been directed by the Comptroller to Specification 1,193,139.

Title: Improvements in or relating to electron discharge devices, such as television transmitting tubes
IPC: H01J29/41
Filed: 1945-07-12
Abstract: 597,532. Cathode-ray tubes electron image tubes. LUBSZYNSKI, H. G. July 12, 1945, No. 17798. [Class 39 (i)] In a television transmitting tube an electron image corresponding to an optical image on photo-electric cathode 5 is projected through a signal plate film 3 and further through an insulating film 2 on to a sheet 1 of conducting glass or material such as enamel of like resistivity and the other side of the sheet is scanned by an electron beam to restore equilibrium potential and provide signals. The image electrons penetrate the films 1 and 2 for suitable potentials applied to cathode 5, conducting film 3 and conducting glass 1, and the cathode 5 may be so close to the composite screen that no electron image focusing arrangements are required. Sheet 1 has resistivity, e.g. 2 X 10<8> to 10<11> ohm cms., and thickness, e.g. 0.001 inch, less than half the scanning spot diameter so that during a frame scanning period the image electrons may spread through from front to back but not considerably laterally. Insulating film 2, which may be 0.0004 inch thick, may be produced by hydrolising ethyl silicate, or evaporating and oxidising aluminium or magnesium, or evaporating an insulator such as a borate or fluoride. And signal plate film 3 may be evaporated aluminium, beryllium or molybdenum 5 to 60 Angstroms thick.

Abstract: 631,411. Vehicle coupling. SOC. POUR L'UNION DES TRANSPORTS FERROVIARIES ET ROUTIERS SOC. ANON. July 7, 1947, No. 17879. Convention date, July 29, 1946. [Class 103 (v)] In a coupling for a trailer, the tow bar 1, which as shown is of the type designed to run up a ramp on the tractor, is linked with the rear frame 2, 3 of the trailer by connecting rods 5 and 7 in such a way that the tow bar tends to swing to the retracted position shown in Fig. 3, under the action of gravity. In this position the tow bar 1 is secured by the pivoted hook 10 engaging the pin 14. The tow bar is raised to the position shown in Fig. 4, preparatory to its full elevation on engagement with the ramp on the tractor, whereupon the spigot 16 engages the socket 17 on the trailer frame. To obtain increased tilting of the trailer, a cover 17a may be placed over the socket 17 so that the rear of the trailer is elevated as the tow bar runs up the ramp.

Title: Improvements in or relating to the preparation of salts of penicillin
IPC: C07D499/00
Filed: 1947-07-07
Abstract: Salts of penicillin are manufactured by the action of a salt or salts of a suitable primary organic base or bases and a suitable organic acid or acids on penicillin dissolved in a suitable solvent or mixture of solvents, preferably containing a quantity of one or more suitable secondary solvents.  Suitable primary organic bases are compounds of the general formula R.NH2, wherein R represents a hydrocarbon residue containing, in the case of an alkyl or alkenyl group, not more than 4 and in other cases not more than 8 carbon atoms, which compound has a PKH value of not less than 10.2, and, under the conditions of the process, does not rapidly destroy penicillin, e.g. cyclohexylamine, methylcyclohexylamines, ethylamine, isopropylamine and n-butylamine.  Suitable organic acids are aliphatic or substituted aliphatic acids having not more than 8 carbon atoms in the straight chain, e.g. formic, acetic, propionic, butyric, isobutyric, caprylic, phenylacetic, glycollic and malonic acids. Suitable solvents are solvents into which penicillin can readily be extracted, which are relatively inert to penicillin, and in which the primary organic base salts of penicillin are relatively insoluble, e.g. amyl acetate (preferred), diethyl ether, butyl acetate and methyl isobutyl ketone.  Suitable secondary solvents are solvents in which the primary organic base salts of penicillin are relatively insoluble but those of the impurities normally present are soluble, e.g. ethyl alcohol, preferably in the proportion of 2-10 per cent of the main solvent.  The primary organic base salts may be converted into metallic (e.g. sodium or calcium) salts of penicillin. Examples describe the preparation of the cyclohexylamine salt of penicillin.  Specifications 606,482, 610,731 and 622,988 are referred to.  Samples have been furnished under Sect. 2 (5) of the ethylamine and isopropylamine salts of penicillin.

Abstract: 440,262. Escapement mechanism. EYNDE, M. VAN DEN, 30, Rue des Deux- Eglises, Brussels. June 16, 1934, No. 17889. [Class 80 (iv)] [See also Group XXXVIII] Escapement mechanism for imparting stepwise rotation to a shaft 1, driving an element such as a pointer 5, or an astronomical telescope, comprises a detent-pin 36 which is periodically released from notches 38 in a flange 37 secured to the shaft 1, in order to allow the permanent torque of an electric motor 7, acting through an elastic coupling 40, to turn the shaft in steps. The detent-pin 36 is periodically withdrawn from the notches 38 by an electromagnet 29, and such withdrawal breaks the circuit at 31, so that when the next notch 38 underlies the detent-pin the latter is pressed into it by a spring 35, this action being continuous and automatic. The amplitude of the steps a, b, c may be varied by changing the flange 37 or by inclusion of a variable-speed gear 49. The driving motor 7 is reversible under control of a manual commutator switch 9, in the circuit of which is a polarized relay 19, which breaks the independent circuit of the escapement electromagnet 29 when the motor is switched off. The elastic coupling 40 comprises loose rubber rings 44, and the inertia of the driven device is such that it will complete a step even if the motor is reversed during the movement.
