Title: Improvements in and relating to Ohmic Contacts.
IPC: H01L21/285
Filed: 1966-07-20
Abstract: 1,157,581. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 20 July, 1966 [22 July, 1965], No. 32506/66. Heading H1K. [Also in Division C7] An ohmic contact is made to a silicon semiconductor body by depositing aluminium and more silicon on to the body and simultaneously or subsequently forming from the deposited materials an Al-Si alloy in which the Si content is 2 to 3%. The deposited alloy is itself alloyed to the body to form the contact. Fig. 2 (not shown) depicts a Si body on which the required Al-Si alloy has been deposited by evaporation of A1 whilst holding a source of Si close to the body. In Fig. 3, layers 25, 26 and 27 of A1, Si, A1 respectively are evaporated on sequentially and a subsequent heat treatment effects alloying. In both forms the body is first oxide masked, using a photo-lithographic technique, and the Al-Si deposited through a hole in the oxide to form the contact material and also over the oxide to form a land for connection of a lead at a point remote from the contact. Subsequently, a protective glaze 23 (Fig. 2, not shown) is applied by depositing fritted glass and heating to its fusion temperature. Fig. 1 (not shown) depicts what would happen in such a glazing step were the contact material pure aluminium; the aluminium of such a contact would migrate considerably into the body with deleterious results. This disadvantage is overcome by the invention's use of Al-Si alloy as the contact material.

Abstract: 1,055,457. Warehouse storage and withdrawal system. S.A.M.E.T.O., (SOC. D'APPLICATIONS MECANIQUES D'ELECTRICITE ET DE TOLERIE). Aug. 12, 1964 [Sept. 3, 1963], No. 32892/64. Heading A4T. In a method for the automatic withdrawal, storage or inventory of articles held in containers occupying predetermined positions in a store, the articles are given a reference and each container a code of two or three co-ordinates according to its position in the storage bays, a memory unit associated with each article records, via an electric accounting machine, the incoming and outgoing quantities of an article typed on a typewriter, both accounting machine and typewriter being capable of receiving or transmitting signals, the number of any article being fed from the accounting machine and the typewriter to a group of four illuminated decade-counter tubes for display to an operator, and initiating for storage or withdrawal the action of a handling device moving according to the coordinates of the article. The operator types out the reference of the article to be stored or withdrawn and the number of pieces, the decade tubes indicate the number available and the accounting machine, via the memory unit for the article, relays and a step-by-step unit, adds to or subtracts from the number available and at the same time the handling device moves according to the coordinates between a loading and unloading position and the position of the selected article container. The handling device is controlled by the memory unit in that it only functions for withdrawal if there are sufficient articles in store. A signal indicates otherwise. By typing out the article reference and operating an inventory key an inventory of the articles is obtained which is shown on the decade tubes and printed on the typewriter via the memory and step-by-step units.

Title: Improvements in cleansing compositions
Filed: 1945-12-11
Abstract: Cleansing compositions, particularly for artificial dentures, comprise an oxygen-liberating compound other than an alkali-metal percarbonate, an activating agent and an alkaline material, the ingredients being so proportioned that a dilute aqueous solution of the composition has a pH of from 9.0 to 10.5.  The alkaline material, e.g. sodium carbonate and sodium bicarbonate may function as a buffer to maintain the pH within the above range and preferably within the range 9.2 to 10.2.  The oxygen liberating compound may be an alkali metal perborate, perpyrophosphate or urea peroxide, and the activating agent may comprise a water-soluble alkali-stable substance coated with a material, e.g. an organic carboxylic acid not more than slightly soluble in water but capable of forming water-soluble salts with alkalis, capable of preventing interaction between the oxidising compound and the activating agent during storage.  The activating agent may be a complex of a hydroxycarboxylic acid, e.g. gluconic acid with a metal, e.g. cobalt which is capable of existing in at least two states of oxidation.  Methods are given for the preparation of cobalto-gluconate and similar complexes and for coating them with higher fatty acids.  The composition may include a wetting agent and a dye, e.g. phenol phthalein, which will become colourless after the composition has been dissolved in water for a predetermined period. One of the compositions exemplified consists of 250 parts by weight sodium perborate monohydrate, 125 p  of sodium carbonate and bicarbonate respectively, 10 of an activating agent, and 0.1 of sodium lauryl sulphate.

Abstract: 1481301 Discharging molten metals BICC Ltd 16 July 1974 [16 July 1973] 33734/73 Heading F4B [Also in Division B3] Molten metal, e.g. Al, Cu or an alloy of one of these metals, flows from a furnace, tundish 1 or other container directly or indirectly into a stationary or a moving-wall mould, such as a wheel-and-band mould, at a rate determined by an alternating magnetic field established about the stream so as to set up an electrodynamic force in the stream, which force (e.g. controlled manually or automatically according to the level of the metal, in the mould and, possibly in the container) compresses the stream to reduce its cross section so that there is little or no contact with the walls of the outlet 2. Since it is necessary to use a control stopper at the start and finish only, there is little wear of the outlet and stopper. The level of the tundish 1 is preferably maintained constant by intermittent feed or continuous feed 4 from a holding furnace. The throat 5 of the silica outlet spout 2 may be shaped more gradually to the bottom of the alumina container 1 so that the induction coil 3 can surround it as well as the spout. The electromagnetic field may tend to drive the stream in the reverse direction as well as to compress it The current frequency may be 7kHz and the voltage may be adjusted to vary the field.

Abstract: 173,953. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Nov. 30, 1920. Systems for continuous-current motors only; braking.-Motors are controlled for high speed and light load, as in lowering after hoisting duty, by opposing part of the field to the remainder, while keeping closed a rheostatic braking-loop which, if called upon, comes into action with the two parts of the field acting cumulatively. According to one arrangement, a motor having an armature a, and two field-windings f, f<1>, which act additively and in series with the armature during hoisting, is, at the full-on lowering stage, changed over from the condition shown in Fig. 4 to that shown in Fig. 5, by means of an extra controller segment 12<b>, and a finger 12 connected to a tap between the winding f, f<1>. The effect is that the winding f is opposed to the winding f<1> as long as the machine is motoring, but combines additively in the rheostatic loops n<9> when the machine is called upon as a brake. In modified arrangements, the change-over is caused to take place at a earlier stage in lowering, and one of the windings is kept short-circuited until the change takes place. The two windings may be the series and shunt windings of a compound motor. Separate electromagnetic contactors may be used for making all the circuit changes, and may be combined with an automatic relay for deferring the field change until the motor has acquired a definite speed.
