Abstract: 1,257,698. Polarized bi-stable electromagnetic relays. STANDARD TELEPHONES & CABLES Ltd. 18 Sept., 1969, No. 46043/69. Heading H1N. A polarized bi-stable electromagnetic relay has two magnetic contact units 120 disposed at opposite ends of a permanent magnet 121 which is part of two magnetic circuits arranged so that pulse energization of an operating 129 winding changes the amount of flux passing though the contact units by dispersion of flux from one magnetic circuit to the other. The contact units may be any of the types described in Specifications 1,026,564, 1,026,565, 1,026,567, 1,063,145, 1,094,334, 1,098,145, 1,099,081, 1,115,401, 1,119,126, 1,126,869, 1,131,928, 1,142,086, 1,213,699, 1,219,556 and 1,250,930. The first flux path extends from the permanent magnet 121 to an inner magnetic member 2 of one contact unit through its lamina armature or armatures to its outer magnetic member through a magnetic cover 133 then through the other contact unit to the second inner member to the other pole of the permanent magnet. The second flux path extends from the permanent magnet 121 to an inner member 2 across an annular gap set by an insulator 125 then along a magnetic tube 126 on which the coil 129 is wound, about an insulator 127, and across a second insulator 125 to the other inner member 2 adjacent the other magnet pole. The members 2 are separated from the permanent magnet 121 by insulating washers 122.

Abstract: 1,258,126. Colour-recording cartridge; optical filters. RCA CORPORATION. March 31, 1969 [April 4, 1968], No. 16717/69. Headings G2A, G2C and G2J. A colour-encoded record of a coloured subject is made on black and white film by photographing through a polychromatic filter which comprises sets of strips, the sets being disposed at an angle to each other, and each set consisting of alternate coloured and transparent strips, the colour being different in each set. The filter forms part of the film cartridge. The form of filter shown in Fig. 4 has a first horizontal set of strips consisting of alternate yellow and transparent strips Y, T. A second set of strips, inclined upwards at 60 degrees to the first set, consists of alternate magenta and transparent strips M, T. A third set, inclined downwards at 60 degrees to the first set, consists of alternate cyan and transparent strips. The size and spacing of the strips are such that the filter has the characteristics of a diffraction grating. As shown in Fig. 3, the filter 16 mounted on a transparent substrate 21 is built into the film cartridge 15 opposite the exposure window 19. The film 14 winds across from the supply reel 17 to the take-up reel 18, and is actually in contact with the filter, although shown as spaced therefrom for clarity. To reconstitute the picture of the subject, the encoded black and white negative is converted to a positive transparency. Collimated light is passed through this and then focused on to a decoding filter mask (26), Figs. 5 and 6 (not shown), thence on to a viewing screen (28).

Abstract: 1295516 Cathode-ray tube circuits SANDERS ASSOCIATES Inc 16 Feb 1970 [20 Feb 1969] 7415/70 Heading H4T In a magnetically deflected cathode-ray tube pincushion distortion is corrected by controlling the magnitude of the X (horizontal) and Y (vertical) deflection signals as a function of the radial distance of the beam spot from the centre of the screen. The specification includes a mathematical analysis of the problem and shows that a close approximation to the desired control function is a square law function. Thus, a control voltage function E<SP>2</SP> = X<SP>2</SP>+Y<SP>2</SP> is generated and employed to control attenuators, each comprising a variable resistor (which varies as the inverse function of the control input) connected in shunt with the input to the respective X and Y deflection amplifiers. Fig. 5 shows one embodiment in which the absolute values X and | Y | are derived from the deflection signals in circuits 14, 16 and after squaring in circuits 18, 20 are combined in a summing amplifier 22 and supplied to the attenuators 24, 26 which may comprise metal oxide semiconductor field effect transistors (MOSFET) 40, 42 as shown in Fig. 6. Other devices such as junction field effect transistors (JEFT), light controlled resistors and photo optic devices may be employed. These, however do not vary as an inverse function of the control input and E must be raised to some power n. This may be effected by deriving the square root of E and then raising it to the nth power or, as described with reference to Fig. 7 (not shown) the output of summing amplifier 22 (Fig. 5) may be multiplied by E<SP>n-2</SP> before application to the voltage controlled attenuators.

Abstract: 1315917 Plasma spray gun nozzle SEALECTRO CORP 10 Sept 1971 42279/71 Heading B2F A spray nozzle for a plasma spray gun has an axial opening through which the plasma gases are ejected, a flat end face perpendicular to the nozzle axis and a plurality of equally spaced helical grooves 22 formed in the outside surface of the nozzle and terminating at the nozzle face, for providing jets of air which surround and limit the plasma spray. Fluent powder, e.g. polytetrafluoroethyline enters through flexible tubes 15, 16 from a reservoir under pressure, and is forced into conduits 17, 18. Meanwhile gas forced through the one chamber at 13 is given a helical direction causing the plasma to turn on its axis as it passes through and out of the nozzle. The powder is thus mixed evenly with the plasma in the space near the gas surface. Helical grooves 22 control the ejected gas flame by providing a helical path for air drawn from the atmosphere by the reduced pressure near the nozzle face. The grooves are in the same direction as the circular motion given to the plasma gas.
