Abstract: 664,883. Test boxes. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Aug. 28, 1950 [Sept. 3, 1949], No. 22884/49. Class 38 (i). [Also in Group XL (c)] Two oscillation generating circuits having their outputs coupled to a common load and having automatic means for transferring an energizing potential from the working to the standby circuit in the event of failure of the working circuit are provided with a mechanical interlocking arrangement which prevents both circuits being energized while they are both connected to the load. A multi-frequency generator has each frequency output coupled to the corresponding load by one of the straps 17 and has a common power supply switch 20 for test and maintenance purposes which is normally protected by a sliding cover 10. Projecting plates on the back of the cover are located opposite the straps so that until the straps are removed the cover cannot be slid to the right to expose the switch. To operate the switch a plunger is withdrawn which then projects sufficiently to prevent the cover being restored to its left-hand position until the plunger is depressed. Testing points 19 are provided beneath the cover and screens 18 are located between each pair of generators.

Title: Improvements in the production of cycloaliphatic ketoximes and their hydrochlorides
Filed: 1956-07-26
Abstract: Cycloaliphatic ketoximes and their hydrochlorides are prepared by the reaction of cycloaliphatic hydrocarbons with nitrosyl chloride in the presence of added hydrogen chloride and/or nitric oxide while irradiating with light to form the hydrochlorides and, if required, treating the hydrochlorides with an inorganic base to form the free ketoximes.  Suitable cycloaliphatic hydrocarbons are cyclopentane, cyclohexane, cycloheptane and cyclo-octane and their alkyl substituted derivatives.  The process may be carried out at a temperature varying from - 50 DEG  C. to 40 DEG  C.  The hydrogen chloride may be dissolved in the hydrocarbon with nitrosyl chloride, or a mixture of nitrosyl chloride and hydrogen chloride may be pumped through the hydrocarbon.  The nitric oxide is preferably pumped with nitrosyl chloride through the hydrocarbon, and hydrogen chloride may be mixed with the nitric oxide.  In the examples cyclopentanone oxime, cyclohexanone oxime, cyclo-octanone oxime and isomeric ketodecahydronaphthalene oximes and their hydrochlorides are prepared.

Title: Method of manufacturing an oriented product of a synthetic crystaline polymer
IPC: B29C55/04
Filed: 1972-05-18
Abstract: 1356081 Oriented films FURUKAWA ELECTRIC CO Ltd 18 May 1972 [22 May 1971 4 Nov 1971] 23355/72 Heading B5B A uniaxially oriented film of a synthetic crystalline polymer is drawn in substantially the direction of the orientation axis of the material to a draw ratio of at least twice the original dimensions in the direction of drawing, at a temperature of more than 30‹ C. below the melting point of the polymer, and soluble portions of the drawn material are extracted in a solvent while applying a tenstile stress to the material in the direction of drawing, the temperature of the solvent being from 2‹C. above to 10‹ C. below the temperature at which the drawn material would be dissolved in the solvent when no tensile stress is applied to the drawn material. The starting material may be made by solidification from molten polymer having a degree of birefringence #n greater than 0À5 x 10<SP>-3</SP>. Polyolefins are preferred, especially a-axis oriented high density polyethylene, but polypropylene, polycaprolactam and polyethylene terephthalate are also exemplified. Films may be made by T-die extrusion, inflation, or calendering, and the extent of their orientation is obtained by X-ray diffraction measurements. Drawing may be effected more than 10‹ C. above the glass transition temperature of the material, and the tensile stress applied may be less than the tensile strength of the drawn material in the solvent and greater than 10% of the yielding stress of the drawn material in the solvent. The extraction step may be accompanied by ultrasonic irradiation, and may be brought to an end when 40 to 95% by weight of the drawn material is extracted. In examples, polyethylene is extracted in xylene or in toluene, polypropylene is extracted in xylene, polyethylene terephthalate in a 50 : 50 by weight phenol : chloroform mixture, and polycaprolactam in 90% by weight aqueous phenol solution. Film so treated shows enhanced tensile properties, compared with film oriented in conventional manner.

Title: Improvements in or relating to printed circuits
IPC: H05K3/20
Filed: 1958-07-22
Abstract: 894,256. Etching. HANLET, J. M. N. July 22, 1958 [July 22, 1957], No. 23494/58. Class 100(2) [Also in Group XXXVI] In a method of making printed circuits (see Group XXXVI), a printing plate is formed of magnesium, chromium or of a ferro-chromium alloy and is coated with a film of nickel oxide Ni 2 0 3  by heating in a vessel in the presence of vapours of nickel bromide, iodide or chloride in ethyl alcohol. A negative of the required circuit pattern is next formed on the oxide-coated surface by applying asphalt or bitumen by the silk screen process to the parts not corresponding to the conductors in the finished circuit. The following photo-etching process is described as an alternative to silk-screening: The oxide coating is sprayed with a photo-sensitive emulsion containing fish glue, erythrosin, ammonium bichromate, and ammonia. After drying, a contact print of a positive transparency of the required circuit is made on the plate using an ultraviolet source. The plate is developed in warm water which removes all the unexposed emulsion. The plate is then heated and the parts of the oxide coatings not protected by emulsion are then etched away by spraying the plate with an aqueous solution of sodium nitrate, sodium pyrophosphate, methyl alcohol and powdered zinc. Hydrochloric acid is then poured over until the zinc is dissolved. This process reduces the oxide to expose the parts of the metal corresponding to the conductors of the finished circuit. The resist is then removed with turpentine or hot water. Alternative materials Complex coatings of iron, bismuth and antimony oxides may be substituted for nickel oxide.

Abstract: 1,272,194. Mechanical data stores. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 15 May, 1970 [20 May, 1969], No. 23692/70. Heading G4B. A device for setting up adjustably variable data, which may subsequently be read, by sensing means and transmitted, comprises a number of plates S, Fig. 1, with holes L, the plates each being movable to a number of positions such that the holes therein, which correspond in size and shape with the holes in a punched card PC also read by the sensing means, occupy positions corresponding to the structure of the rows and columns of the punched card. In the embodiment described the depression of a key on keyboard (T) selectively energizes a number of magnets (H 1 ) to (H 4 ) (Figs. 2a, 3a, not shown) the movements of associated armatures (A 1 ) to (A 4 ) determining the subsequent displacement by crank (14) of a differential driving mechanism, comprising levers (10), (11) and (12) and ties (9), which influences slide 16, through lever (19). A slide 6 carried by slide 16 moves a toothed rack 15 which is held in the set position by lock 13, each rack 15 being associated with a plate 15<SP>1</SP> of the adjustable memory. The value set up is indicated visually by a ciphered extension 20 (see also Fig. 4, not shown). The return of the differential driving mechanism to its normal position by crank (14) unlocks the switching lock 5 to allow slide 6 to move one step into a position in which the next rack may be set. The number of bits of data that must be introduced before the sensing operation is released may be controlled by solenoids S 1 , S 2  and S 3  which selectively rotate cams 27 on shaft 26 into the path of an abutment cam 28 on the slide 6. When a switch 25 is closed by the movement of shaft 26 the sensing operation is released and further introduction of data blocked. To reset the device a solenoid (M 1 ) is energized, acting on lever 23 to return the slide 6 to its initial position. The return of slide 6 may be blocked by a rotatable cam 29 operated by a solenoid F 1  to retain some of the bits of data as a semivariable memory. To erase the semi-variable and variable memories solenoids (M 2 ) and (M 3 ) respectively are energized to free locks 13.
