Title: Multichannel information recording and reproducing systems
IPC: H04S3/02
Filed: 1974-06-14
Abstract: 1468179 Quadraphonic systems EMI Ltd 14 June 1974 [5 May 1973] 21523/73 Heading H4R In a matrix encoder for a multichannel record/reproduce system, which can be utilized with an 'SQ' (Registered Trade Mark) decoder and with a decoder providing discrete signal outputs, first, second, and third, input signals are combined to provide first and second output signals, in which at least one of the input signals has a different phase in each of the output signals, and second, third and fourth input signals are combined to provide third and fourth output signals, in which at least one of the input signals has a different phase in each of these two output signals. Preferably two of the total of four output signals are modulated on respective subcarriers which are combined with the other two signals for recording or transmission on two channels. As described the encoding matrix, Fig. 1, comprises combining networks 5, 6, 7, 8, 15, 16, 17, 18, and phase shifters 9 to 14 which produce output signals SLO and SL from the input signals L F , R B  and L B  and output signals SR and SRO from the input signals R F , R B  and L B  with the relations The signals SLO and SRO are both limited to a band width of 3 kHz, modulated on respective carriers of 20 kHz, and added to the respective signals SL and SR for recording on the walls of a record disc groove, tracks of a magnetic tape, it is suggested that the signals could be transmitted by broadcast techniques. The decoder Fig. 3 provides appropriate demodulations, phase shift, and combination, to reproduce the original signal L F , L B , R F  and R B . The signals SL and SR are identical to those produced in the "SQ" (Registered Trade Mark) matrix and can therefore be decoded by an "SQ" decoder.

Abstract: 933,891. Conveyers; bag gripping devices. SOVEX Ltd. May 29, 1962 [June 16, 1961], No. 21854/61. Classes 78 (1) and 78 (4). Loads are released from a conveyer by the action of a release ramp 16 actuated by two electromagnets 18, 19 acting on a toggle mechanism. The magnets 18, 19 respectively act to rotate the ramp 16 to load releasing and inoperative positions. An endless chain 2 guided by rollers 3 running on flanges 4 of a runway 5 has hangers 1 depending from the chain 2 to support mailbags by means of gripping jaws comprising a downwardly forked body 7 and a serrated face 11 of an associated cranked arm 12 pivoted at 13. The weight of arm 12 holds it against the face 9 and the weight of a bag supported between faces 11, 9 tightens the clamp. The ramp 16 is mounted on a shaft 17 which may be rotated so that the ramp occupies either an inoperative position 16a or an operative position 16b. Electromagnets 18, 19 are pivoted at 118, 119 to a base plate 20 and at 27, 28 to a semicircular toggle 29. Pivot 27 is connected by pivoted levers 32, 34 to shaft 17 so that electromagnet 19 being off energizing electromagnet 18 rotates the ramp 16 into the operative position 16b. In this position the ramp 16 is engaged by the upper end 15 of an approaching arm 12 which is thus turned outward about the pivot 13 and releases the suspended bag. Switch means 36 operated by a cam 35 on the toggle 29 ensures that neither of the electromagnets is continuously energized.

[Also in Division E1] A roofing member is formed by applying to roof-decking material, such as wood-wool, asbestos or polystyrene, a layer of an uncured elastomer and a layer of a cured elastomer, and heating and pressing the assembly so that the uncured elastomer bonds the cured elastomer to the decking material. The decking material may be sized with glue size before the other layers are applied. The uncured elastomer may be natural rubber, soft uncured butyl bitumen or butyl coumarone polymer, and the cured elastomer may be neoprene or P.V. nitrile. Pressing preferably takes place at between 100‹ and 200‹ C. for between 1 and 2 minutes. Joints between adjacent roofing members may be sealed by using strips of cured and uncured elastomers and applying heat and pressure, e.g. by a heated roller. Alternatively, at each joint, uncured and cured elastomeric layers are applied to each member and their edges are upturned, pressed together and covered by an inverted U-section metallic strip, which is crimped in position.

Abstract: 799,266. Tanks. WIGGINS, J. H. Aug. 2, 1955, No. 22172/55. Class 69 (1). A method of building a cylindrical metal storage tank such as that described in Specification 799,265 consists of building up two or three stiff ring-shaped members on the bottom of the tank concentrically with a central roof support, securing roof plates to the members to form two concentric surfaces meeting at an angle in radial section, and then raising the roof and securing it to the tank wall and central support so that the circular juncture of the two surfaces forms the lowest line of the roof. Fig. 6 shows the roof, consisting of surfaces A and B between rings D and E and V-section member 4 hoisted to its final position by temporary winches 8 and pulleys 6 and 9. The roof plates of the centre surface may be segmental in shape, and secured by their ends to members 4 and D before the roof is raised; the centre member D is then raised sufficiently to give the surface the necessary curvature and the longitudinal edges of the plates welded together.
