Abstract: 1286674 Semi-conductor devices DEFENCE SECRETARY OF STATE FOR 9 June 1970 [10 June 1969] 29476/69 Heading HlK A transferred electron device has an ohmic cathode and a non-ohmic anode giving efficient current carrier extraction. In the GaAs embodiment shown both electrodes include an n+ region 13, 15 diffused or epitaxially deposited in an n type epitaxial layer 1 on a semi-insulating substrate 3. The nn+ junction between the region 13 and the layer 1 provides the non- ohmic anode contact, where as a metal layer 17, e.g. of Sn, In or alloys thereof, is situated across the cathode nn+ junction and provides the necessary ohmic contact. Various surface configurations for the n+ region 15 and metal layer 17 are described, and the region 15 may have a depth less than, equal to or greater than the epitaxial layer 1. In modifications the region 15 is omitted, the cathode contact being made direct to the metal layer 17, and the nn+ anode junction is replaced by a Schottky barrier. A series chain of devices of the type shown may be formed in a single semi-conductor body, the n + anode region of one device constituting part of the cathode of the succeeding device and carrying a shorting metal layer 17 on its trailing edge to provide the requisite ohmic contact.

Title: Method for producing cellular natural or synthetic rubber material
IPC: C08L21/00
Filed: 1954-10-15
Abstract: Cellular rubber is prepared by forming a paste of natural, artificial or reclaim rubber latex by increasing its viscosity and chemical stability by the addition of a natural saponifiable resin and water glass, incorporating into the paste a dispersion containing vulcanizing ingredients and possibly an inert filler, and expanding the mixture and heat-treating it to effect vulcanization.  The expansion may be effected by incorporating a blowing agent into the paste, or by frothing the paste in admixture with frothing and heat sensitizing agents prior to the heat treatment.  In an example the mix to be heat treated consists of 100 parts by weight of chemically stable paste comprising natural, artificial, or reclaim rubber latex incorporating 10 per cent of water glass and 5 per cent of saponifiable natural resin (with or without an inert filler), 2 parts blowing agent, and 12 parts of an aqueous dispersion of vulcanizing ingredients.

Title: Improvements in or relating to electrophotographic apparatus
IPC: G03G15/26
Filed: 1962-08-03
Abstract: 1, 021, 882. Electro-photographic processes. RANK XEROX Ltd. Aug. 3, 1962 [Aug. 11, 1961], No. 29924/62. Heading G2H. [Also in Division H1] An electro-photographic plate is capable of being uniformly changed at its first surface which is insensitive to visible light, and may be selectively discharged to form a developable electrostatic latent image at the first surface by a radiation pattern applied to the second surface. Those plates described which are to be used with visible (or near visible) light have the photo-conductive layer with its second surface in contact with a transparent support. In one process the plate is mounted in a slide holder fitted with a dark slide to cover the light sensitive surface. The plate is corona charged in the holder with the slide in position and then exposed with the dark slide removed in a light-tight camera. The dark slide is replaced and the plate may then be subjected to the further steps of development and image transfer in ordinary daylight. In the apparatus of Figure 4 (not shown) the plate 10 is held within a box 50 with its light-insensitive face exposed through an aperture. An original may be placed on side 52 and swung into position in the box. The plate is charged by a corona discharge from grid 57 and then exposed by means of the optical system 53, 54, 55 in the box. Lips 58 on the box hold developer powder so that cascade development may be achieved by rocking the box. The charging grid 57 is pivoted so that it may be swung clear for the insertion of paper and then swung back for use in transfering the image from plate to paper. In the apparatus of Figure 5 (not shown) the plate 10 may be moved to a position within the box 50 for initial corona charging and then to a position flush with the walls of the box for development, as with the apparatus of Figure 4. In this case, however, a roller 41 connected to a high voltage supply is used for the image transfer process. With both these apparatus the operator may work in ordinary daylight. In xero-radiography using a plate sensitive to X-rays, y-rays, #-rays, or to other high energy radiation the support may be made opaque to visible radiation so that the plate may be used in daylight. Exposure to the high energy radiation may take place at the first surface of the plate or at the second surface if the support is sufficiently transparent to the high energy radiation.

Abstract: 607,614. Loading platforms; fittings for loading vehicles. BLOEMERS, G. F. Nov. 9, 1945, No. 30028. Convention date, Nov. 21, 1940. [Class 78 (iv)] In a system for transferring package freight from long distance means of conveyance to short distance means of conveyance, the freight is trucked from the long distance means of conveyance across a stationary platform and deposited on boards corresponding to various destinations and suitably spaced on a platform adapted to travel parallel to the stationary platform on the side opposite to that on which the long distance means of conveyance is disposed, the loads being conveyed by the platform to the short distance means of conveyance on to which they are loaded. The Figure shows an embodiment in which freight is transferred from railway wagons to motor vehicles 5. It is transported in trucks across the platform 1 from wagons 2b, 2c, 2d and deposited on to one of two platforms 3 in spaces between boards 4 where the packages are sorted according to destination. They are then placed in appropriate positions on the boards and the platform is then drawn along to a position opposite the wagons 2e, 2f, 2g and the freight similarly loaded on to the boards 4. When completely loaded, the platform is drawn along into a parking area A.for motor vehicles, where each board is loaded into a vehicle 5. By reversing the operation goods collected in the vehicle 5 may be transferred to the railway wagons 2. To overcome the difficulty of driving a motor vehicle backwards to position it correctly in alignment with the platforms 3, telescopic channel irons are hinged by universal joints to the outer side of the platform so that when swung into a substantially horizontal position they form extensions of transverse guide-ways on the platform. The boards 4 and platforms 3 may run on wheels or on rollers, or the platforms fitted with shoes and displaced by a winch.
