Title: A method of electrostatic recording
IPC: H04N5/82
Filed: 1961-12-29
Abstract: 1,018,933. Electrophotographic processes. GENERAL ELECTRIC CO. Dec. 29,1961 [Dec. 29, 1960], No. 40102/65. Divided out of 1,018,931. Heading G2H. Information in the form of a pattern of electromagnetic radiation is recorded on a photoconductive thermoplastic medium by applying a uniform electrostatic charge to the medium, producing a pattern of electromagnetic radiation representing the information on the charged medium and heating the medium so that it deforms according to the pattern of charges thereon. The uniformly charged medium may be selectively discharged in strips before exposure and the information on the deformed medium may be read by means of a Schlieren system. As shown, a heat-deformable photoconductive thermoplastic tape 1 is passed under corona discharge 6 of 7500 to 8500 volts and the uniformly charged tape is passed under grid 16 and ultra-violet lamp 12 to discharge the tape into strips. The tape then is exposed to transparency 13 by lamp 12, the tape being grounded by metal rollers 15 on an electrically conductive layer 20 and an electrically insulating support 21. The latent image charge pattern is developed by passing the tape 1 through a heating station 22 comprising electrodes 23 and 24 energized by highfrequency voltage deforming the tape in the charged areas. After heating the tape passes a phase contrast microscope 27 so that the deformations can be studied. The information on the tape is retrieved by a flying spot scanner 32, the spot being projected through the deformed storage medium on to a Schlieren optical system and a photo-cell 35 which produces electrical signals corresponding to the deformations. Alternatively, the charged tape may be electrically grounded after exposure and before heating. Other electromagnetic radiation such as visible light, X-rays, and gamma rays may be used. The thermoplastic photoconductive medium used may be that described in Specification 1,018,932 and the apparatus may be that of Specification 1,018,931.

Abstract: 937,966. Floating roofs for tanks. J. H. WIGGINS. Nov. 10, 1961 [Nov. 21, 1960], No. 40300/61. Class 69 (1). A sealing mechanism for a tank having a floating roof with upstanding peripheral side walls 24 between which and the tank wall 12 an upstanding annular sealing element 40 of composite construction is arranged with its top above the top of the liquid in the tank and its bottom submerged in the liquid 11; which element 40 comprises overlapping segments 41 of steel or reinforced plastic supported on the wall 24 by pantograph linkages 70, connected by clamping elements 50 and urged outwards by resilient cellular blocks 60 to press against the tank wall the upper sealing section 81 of synthetic rubber-like diaphragm 80 whose middle section 82 lies in contact with the surface of the liquid 11. The diaphragm 80 is attached to the element 40 and to the wall 24 as shown in Fig. 2 and conforms with the walls at 82a and 82b due to gravity and fluid pressure respectively. An outlet pipe 98 can relieve pressure and vapour. The diaphragm moves up and down with the liquid as indicated by the dotted lines if the weight is increased by snow &c. on the roof. A weather shield 100 is fixed to the top of the element 40. In an alternative shown in Fig. 7, the segment 141 is shaped to permit interposition of a cushioning layer 143 and an air-space 142. An air space may be provided with a flat segment by relieving the mid-portion of the sealing diaphragm 81 (Fig. 8, not shown). Another alternative assembly of segment, diaphragm and cushion is illustrated in Fig. 9 (not shown).

Title: Improvements relating to multi-aperture magnetic devices

Abstract: 1,117,895. Circuits employing bistable magnetic elements. MULLARD Ltd. 19 Aug., 1965 [14 Oct., 1964], No. 41891/64. Heading H3B. In a laddie two side rails and one of the rungs defining one of the main apertures are each provided with an auxiliary aperture, input windings being wound through the apertures in the other side rail. The core may be used in a binary adder, two carry sections of which are shown in Figs. 1a, 1b. Input windings 10, 11 are supplied in operation with bi-polar pulses, winding 10 being wound round the outer leg of the upper rail through auxiliary aperture 4 and round half of the rung through aperture 8. Winding 11 is wound around the lower leg of the upper rail and around the same half of the rung as winding 10. Output windings are wound through apertures 5, 7 as shown and prime and drive windings 14, 15 are wound as shown in Fig. 1b. A " 1 " state is indicated when the material on either side of any auxiliary aperture has been saturated in the same direction whereas a "0" state is indicated when the material is saturated in different directions. If the flux around any auxiliary aperture is in the "0" state then a prime pulse switches the flux around the aperture but not sufficiently quick to produce a detectable output. Since the flux pattern is now in accordance with that which is caused by the next drive pulse, of the same polarity as the preceding prime pulse, no flux switching will occur and no output will be produced. If a "1" state is stored around the aperture then the prime pulse has no effect on the flux since it is already in a direction in accordance therewith. The next drive pulse of the same polarity as the prime pulse reverses the flux in the outer leg of the lower rail thus producing an output in the carry winding. The carry output winding of each section is connected to one of the input windings 10 or 11 of the following part of the core, the other input winding of each section being supplied with binary signals to be added. In operation input and drive pulses of one polarity are applied simultaneously generating, where the correct conditions occur, a carry pulse of the same polarity. A slow prime pulse of opposite polarity to the drive signal followed by input and drive signals of the same opposite polarity are then applied to the appropriate windings. By using bi-polar pulses information is read-in concurrently with information which was stored in the preceding half cycle, being read out. Flux patterns during various steps are shown in Fig. 2 (not shown). The input windings 10, 11 may be wound in a figure-of-eight manner through the auxiliary aperture around the rung.
