Title: Unijunction transistor
IPC: H01L29/76
Filed: 1965-03-19
Abstract: 1,100,468. Unijunction transistors. MOTOROLA Inc. 19 March, 1965 [26 March, 1964], No. 11759/65. Heading H1K. In a unijunction transistor, consisting of a semi-conductor body provided with two ohmic base contacts and a rectifying emitter contact, all the contacts are on the same major face of the body but the emitter contact is spaced from the line joining the two base contacts. In Fig. 2, this condition is met by placing the emitter 20 generally in line with the base contacts 18 and 19 but not between them. All the contacts consist of diffused regions surmounted by metallic electrodes. The device is a switching device in which the switch-on voltage VP (applied between the emitter and the first base) is related to the interbase voltage <SP>V</SP>BB and the so-called equivalent diode emitter voltage V D  by the formula in which is termed the stand-off ratio. The location of the emitter contact is chosen such that #=d 2 /(d 1 +d 2 ), where d 1  and d 2  are the respective diameters of the first and second base contacts. As is explained in the Specification with reference to Figs. 4 and 5 (not shown), a suitable location may be determined by applying a known potential difference between the bases. Thus, if V BB  is 10 volts and d 2  = 3d 1 , then the emitter should be located on the chosen major face of the body at a point where potential relative to the first base is about 7¢ volts. The device may be mass produced by dicing a wafer after diffusion, e.g. by photolithographic techniques, of the required contact areas, and an oxide coating may cover at least portions of at least some of the PN junctions-preferably only the actual contact areas are left uncovered. The device is suitable for incorporation in a monolithic integrated circuit or for separate mounting in an enclosed housing 11 (Fig. 1, not shown). The preferred semiconductor is silicon and the diffused-in impurities phosphorus and boron.

Title: Packaging process
Inventor: PICKFORD NIGEL EVANS
IPC: B65B33/00
Filed: 1960-04-05
Abstract: 930,482. Packaging. BRITISH VISQUEEN Ltd. March 29, 1961 [April 5, 1960], No. 12030/60. Class 94(1).  Amanual or mechanised process for packaging objects in a thermoplastic film of polymers or copolymers of olefines, expecially polythene or polypropylene, comprises the steps of supporting across an aperture of any shape a flat film of thermoplastic material having a truly liquid melt, heating the film to bring it to the consistency of a viscous liquid and by relative movement between the object to be packaged and the aperture bringing the object into contact with the film on the side away from the aperture and passing it, covered by the thermoplastic film through the aperture, the package being preferably closed by twisting the thermoplastic film by spinning the object while the film is in the heat sealable state. Alternatively the object may be held in position until the film has solidified and the excess film cut off. In packaging, the film may be held in a horizontal position and the object to be wrapped passed through, either in an upward or downward direction or when packaging objects supported on a tray the film may be held at any angle to the horizontal, including the vertical, and the tray passed sideways in a horizontal plane, through the aperture. Sealing may be carried out by twisting the packages about the vertical axes. In a mechanised process a series of frames comprising the holder and clamping means may be adapted to cut portions of film from a roll, present the portions to a heater or hot air jets and the process may then be completed by hand or mechanical means for dropping or passing the object through the aperture and for holding the wrapped object and finishing the package. The process depends on the rate of heating of the film for packaging of particular objects and for rapid heating of the film the maximum amount of draw obtainable is greater, than can be obtained, for the same amount of sag, when the film has been heated slowly. Specification 838,803 is referred to.
Patent GB-598193-A (GB)
Title: An improved liquid composition for the treatment of the feed water for boilers and its process of preparation
IPC: C02F5/08
Filed: 1945-05-14
Abstract: An aqueous solution for treating boiler feedwater contains an alkali metal carbonate or an alkaline phosphate, a tanning extract or similar organic substance, and caustic alkali, and the preparation of the solution consists in adding the organic substance by instalments to an aqueous solution of the caustic alkali and heating the solution for a time, usually about an hour, before mixing with the alkali metal carbonate or the alkaline phosphate.  The caustic alkali solution contains from 7.5 to 20 per cent by weight of alkali, the number of instalments of organic substance and intervals of time between instalments depend upon the ellagic content thereof, and the heat treatment at a temperature not less than 60 DEG  C. and preferably at or near the boiling point of the solution is for a time sufficient to prevent precipitates forming in the liquid eventually prepared.
