Title: Improvements in or relating to the wrapping of meat
IPC: B65D65/40
Filed: 1950-09-04
Abstract: A composite sheet wrapper for preserving uncooked meat, especially freshly-skinned carcasses, during storage and shipment comprises absorbent fibres adhered to at least one layer of a flexible, extensible, water-resistant film of organic film-forming material having a multiplicity of minute perforations therein, such that the wrapper has a permeability to water vapour of between 0.25 and 2.75 g. per 50 sq. cm. per 24 hr. at room temperature and 100 per cent relative humidity.  The water retention of the wrapper is preferably at least 30 per cent of its dry weight.  The absorbent fibres may be paper, woven, knitted or netted cotton or rayon, a nonwoven fabric such as a felt, web or bat.  The film-forming material may comprise a natural or synthetic elastomer, chlorinated rubber, a cellulose ester or ether, a nylon, polyethylene, or a synthetic resin, especially a polyvinyl resin.  Examples of the wrappers relate to films of polyvinyl butyral and polyvinyl chloride-polyvinyl acetate copolymer of 0.001 inch and 0.002 inch thickness on cotton sheeting, woven cotton cloth, and cotton scrim.  The absorbent fibres may contain dye, a mould-inhibiting agent, a reducing agent such as sodium sulphite to prevent discoloration of the meat surface.  The wrapper may be applied to the meat dry or wetted with sodium chloride solution; the wrapper is applied smoothly and is then fastened with pins, string stitches, or self-binding tapes.  The wrapped meat may be chilled to shrink the wrapper about the meat.

Abstract: 1,272,422. Pulse oscillator. INDUCTOSYN Ltd. 1 May, 1969 [14 May, 1968; 24 March, 1969], No. 22155/69. Heading H3P. [Also in Division G4] In a 4Mc/s pulse oscillator 1, Fig. 2, for a digital measuring system, (see Division G4), with the output of an inverter 35 high a capacitor 26 charges towards + V until the potential across it reaches ¢V causing an inverter 30 to switch and provide a low output which allows a capacitor 31 to discharge until the potential across it reaches such a low level that a further inverter 34 switches to provide a high output, which in turn, causes the first inverter 35 to switch and provide a low output. Thus the output of inverter 35 remained high whilst capacitor 26 was charging to ¢V and whilst capacitor 31 was discharging. With the output of inverter 35 low, capacitor 26 discharges; eventually the output of inverter 30 goes high whereupon capacitor 31 charges towards + V and when its potential reaches ¢V the inverter switches and provides a low output which, in turn, causes inverter 35 to produce a high output. The cycle then repeats.

Title: Improvements in or relating to telegraph transmission by phase reversals
Inventor: PRIOR HECTOR THOMAS
IPC: H04L27/20
Filed: 1950-09-08
Abstract: 693,704. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd. Aug. 31, 1951 [Sept. 8, 1950], No. 22173/50. Class 40 (iii). In a phase-reversal telegraph system employing elements of two kinds, the phase of an alternating current is reversed to signify each element of one kind, e.g. space, and the phase is left unchanged to signify an element or elements of the opposite kind. The transmitter, Fig. 1, includes a timing arrangement as described in Specification 692,411, comprising three ten-gap cold-cathode discharge tubes C1, C2, C3 to which pulses P - are applied from a 5 kilocycle source through gating circuits G2, G3, G4. The numerals within the circles indicate the number of pulses required to open the corresponding gate. Pulses P+, synchronized with the pulses P -, are applied to a gate G1 to which a pulse is also applied in the rest or normal position from the stop tube SP of the flip-flop F1. When a start element is received, the gate G1, which may be of the type described in Specification 636,700, is opened and the start tube ST is fired so that the counting chain is set into operation. Assuming that phase A was being transmitted by the transmitter TR at the beginning of the start element, i.e. tube PA fired, pulses are applied over the space lead and output of the tube PA to the gate G6 which is opened at 10 ms. to fire the tube PB. If the first and subsequent code elements are marks the gates G5, G6 cannot be opened and no change of phase can take place. When the next space element is received the gate G5 is opened and the tube PA is fired to send the phase A. At 138 ms. the tube SP is fired and a transient pulse from the tube ST passes through a gate G7 to reset the multigap devices C2, C3, the units gap being at the zero position, since the number of pulses counted is 690. Receiver arrangement. The first pulse received, corresponding to a transition from stop to start, in combination with pulses P+ and the fired tube SP of F3, opens a gate G8 and fires the start tube ST so that the time scale circuit is brought into operation. The first pulse also changes over the flip-flop F4 from NC to PC, and at 10 ms. a gate G9 is opened to fire the space tube S of the flip-flop F5. One pulse later, i.e. at 10.2 ms. the no-change tube NC is fired. At 30 ms. the condition of the flip-flop F4 is again examined and if the tube PC has not been fired, indicating the reception of a mark, the gate G10 is opened, and the mark tube M of flip-flop F5 is fired transmitting a mark element. At 30.2 ms. a pulse is applied to the tube NC, but this has no effect as NC is fired. At 40 ms. a phase reversal is detected, tube PC is fired and at 50 ms. the gate G9 opens to fire the space tube S of the output flip-flop F5. At 130.2 ms. the no-change tube NC of the flip-flop F4 is fired, and at 138 ms. stop tube SP of flip-flop F3 is fired, extinguishing the tube ST which applies a transient pulse through a gate G11 to restore the time scale circuit to its zero position.
