Abstract: 1367741 Compiling NATIONAL CASH REGISTER CO 10 Oct 1972 [12 Oct 1971] 46571/72 Heading G4A A programming means is arranged to cause a computer to translate a program in a high level source language into an intermediate high level language independent of the source language, executable statements specifying operations to be performed on data being separated from non- executable statements, e.g. statements specifying the characteristics of data. The intermediate high level language is then translated into a second intermediate low level language which is independent of any particular computer and the program is then translated into machine language for a particular computer.  The separation of the translation allows the source language or the computer to be changed without requiring a complete redesign of the compiler. For example if the source language is changed only that part of the compiler relating to translation into the high level intermediate language need be changed. The translation into machine language can be performed at run time on the machine which is to execute the program. The translated program may be stored on cards, tape, disc &c. A Metalanguage is described.

Abstract: The binder comprises a solution of a mixture of sodium silicate and/or potassium silicate with lithium silicate. The sodium oxide and/or potassium oxide : lithium oxide : silicon oxide weight ratio is in the range from 0.80 to 0.99 : 0.01 to 0.20 : 2.50 to 4.5. The overall solids content of the solution is between 10 and 50% by weight. The viscosity of the solution is between 10 and 100,000 cP. The binder can be used for paints, adhesive formulations, adhesive cement formulations, concrete impregnations and foundry cores. However, it is preferably used in the production of welding electrodes. Due to its relatively low lithium oxide content, the binder has high binding strength. For this reason, it is also particularly economical.

[Also in Division B2] In a process for adhering an organic thermoplastic material to a metal substrate the surface of the substrate is treated with an aqueous inorganic acid solution containing no more than the usual trace amounts of salts and containing hexavalent chromium and/or a solution containing an aliphatic carboxylic acid, the metal is rinsed with water, the resulting treated metal is dried, a layer of the organic thermoplastic material is placed on the treated metal surface and the resulting assembly subjected to heat and pressure. In one process described an aluminium substrate is immersed in a substantially salt-free aqueous inorganic acid solution containing chromium trioxide, is rinsed, placed in a second solution containing an aliphatic carboxylic acid, rinsed, and dried. A thermoplastic film is then adhered to the substrate using heat and pressure. If desired either the treatment of the substrate with the inorganic acid solution or the second solution may be omitted. The metal substrate is alternatively tinplate, nickel, iron, galvanized metal, magnesium or combinations thereof. The thermoplastic film may be high or low density polyethylene, polypropylene, polybutene-1, copolymers of ethylene and propylene, or a copolymer of ethylene and maleic anhydride and may contain a filler, e.g. carbon black. The inorganic acid may be phosphoric acid and the aliphatic carboxylic acid may be maleic, acrylic, polyacrylic, citraconic, fumaric, methacrylic, crotonic, glutaric, itaconic, or maleamic acid. The thermoplastic layer may be applied by extrusion coating, as a powder, or as a film and in the latter case may be formed by compression moulding in a press where it is first heated and then cooled. The plastic/metal article produced may be used in making wires and cables, pipelinings, corrosion and chemical resistant protective coatings, packaging materials, or printed circuit boards.

Abstract: 1,218,318. Photographic apparatus. POLAROID CORP. Oct.6, 1969 [Oct.7, 1968], No.48930/69. Heading G2A. The exposure control system of photographic apparatus is arranged to take into account the reflectivity of a subject to be photographed, and of its environment, as well as the distance of the subject from the apparatus, before exposing photosensitive material in the apparatus to the subject which is artificially illuminated during the exposure. The exposure control system is generally set in accordance with the subject to apparatus distance, and then a correction applied depending on the reflectivity and also on the distance, a photosensitive metering technique being used to derive an integrated valuation of the reflectivity. The exposure may be controlled by adjusting the aperture, by altering the exposure time, by controlling the light output from the source of artificial light, or by any combination thereof. In the embodiment shown, the inverse square law input to the exposure system is provided by an aperture adjustment, and the reflectivity correction is provided through the use of an optical wedge 48 of varying density. Diaphragm blades 50, 52 are set by manipulating a control knob 56, and are adjusted thereby until an index pointer 74 on the blade 50 is opposite the appropriate range marking on a flanged section 72 of the blade 52. The reflectivity correction factor is obtained by illuminating the subject with a metering flash 76. Reflected light is received by a photodetector 82, is integrated, and a signal is presented to an automatic gain control (A.G.C.) circuit 88, which also receives a signal from a range factor 90 in dependence on the setting of the pointer 74 and section 72. The output of the A.G. C. 88 is fed to the drive 93 of the optical wedge 48. The exposure is then made using light source 100, and the wedge 48 is reset to a position removed from the exposure aperture of the apparatus.

Filed: 1973-10-24
Abstract: 1439217 Microwave transistor GENERAL ELECTRIC CO 24 Oct 1973 [25 Oct 1972] 49553/73 Heading H1K The collector region of a microwave-amplifying transistor has an avalanche portion adjacent the collector junction and a uniformly doped drift portion extending from the avalanche portion to the collector electrode. The distance between the collector junction and the collector electrode is chosen to be half the saturation drift velocity of majority carriers in the collector divided by the centre frequency of the band to be amplified, and the net activator concentration is chosen to vary along the length of the collector region such that when it is depleted along its length an electric field is produced therein which produces a finite value of conduction carrier multiplication. The material of this collector region should have an avalanche multiplication factor for the majority carriers therein significantly greater than that for minority carriers. Over a wide range of field intensities, silicon is useful for NPN transistors and germanium for PNP. A silicon transistor is typically operated with a bias such as to give an electron multiplication factor in the range 5-50. The net activator concentrations in emitter, base, avalanche portion and drift portion may typically differ in a decreasing direction by steps of two orders of magnitude. The particular silicon transistor shown has a collector electrode comprising the N + substrate 51 and a gold-antimony ohmic contact 67 thereto. The drift portion of the collector is formed by an N- epitaxial layer 52 in which the avalanche portion 53 is formed by diffusion. The base region 55 and its peripheral guard portion are also formed by diffusion. The emitter regions 56 are formed by diffusion from epitaxially deposited N-type silicon 57 forming portions of the emitter electrodes which are completed by aluminium 58 deposited as a single layer with the base electrodes 61 and separated therefrom by etching. The emitter and base metallization is interdigitated.
