Title: Improvements in or relating to multiplex data transmission systems
IPC: G09G3/00
Filed: 1966-04-18
Abstract: 1,104,269. Display apparatus. GENERAL ELECTRIC CO. 18 April, 1966 [19 April, 1965], No. 16864/66. Heading G5C. [Also in Division G1] Control information for remote apparatus in parallel pulse form is converted into serial pulse form, transmitted along a light beam and reconverted at the remote location to parallel pulse form by a receiver comprising a photo-electric device. The invention is applied to the transmission of control signals between illuminated display panels comprising seven rows of lamps each coupled to a shift register so that a message may be made to pass along the panels. Transmitter.-The seven-bit output from one display panel corresponding to the states of one column of lamps is applied to a parallel to serial converter 51, Fig. 3a. On receiving a pulse from a 7.25 mS one shot 46, the 1 kc. pulse generator 47 sends pulses delayed by a one shot 50 to read out from the converter a serial pulse train which is applied, interlaced with synchronising pulses, to a driving circuit 48 for a light-emitting diode in the optical transmitter circuit 42. Receiver.-The 0À2 mS one-shot 81, Fig. 4a, responds to the first synchronising pulse in the output of the photo-electric detector 43, to send two signals, one direct and the other delayed 0À8 mS by one shot 83 to a bi-stable circuit 84. A gating signal is thus produced by bi-stable circuit 84 to select the information pulses and pass them to a serial to parallel converter 86. Synchronising pulses from bi-stable circuit 84 advance the converter 86 as information pulses are fed in and the parallel signal is read out the output of a 10 mS one shot 86 which is set by the first synchronising signal from one shot 81.

Convention date, June 15, 1931. [Class 38 (iii).] Varying E.M.F.-A strip rolling mill motor 13, and a winding motor 14 are fed from a single Ward-Leonard generator 23, and means are provided for interrupting the field circuit 25 of the generator, and disconnecting the mill motor 13, leaving the winding motor 14 still connected and supplied by the residual voltage of the generator, to maintain tension in the working material. The generator 23 is connected to busses 22 by closing a, button 33 to energize a self-maintaining contactor 31. By then closing a button 41, a self-maintaining contactor 39 is energized, and acts. to close a contactor 37 to connect the mill motor 13 to the busses 22. The contactor 37 closes. an energizing circuit of a contactor 45 which excludes a resistance .44 in the. armature circuit of the winding motor 14, and also energizes a contactor 36 which closes the field circuit of the generator 23. The closing of the contactor 36 initiates the sequential closing of contactors 35, 34 to exclude resistance from the generator field and a button 42 is closed to connect the winding motor 14 to the busses 22. When a " stop " button 40 is depressed, the contactor 39 drops out and is followed by the dropping out of the contactors 34, 35, 36, 37, 45 in the order mentioned, so that the generator field is first reduced and then opened, the mill motor is disconnected, and the resistance 44 is put in circuit with the winding motor 14, which remains connected. A contactor 50 controlling the field of the motor 14, is energized in accordance with the load current of that motor and maintains constant tension in the wound strip.

Abstract: 865,505. Indicating liquid levels. FEIGENBAUM, H. May 19, 1959, No. 17028/59. Class 123(1) A liquid-level indicating device comprises two electric coils 22, 23 disposed within a casing 1.1 around a vertical through-pipe 15 which slidingly receives, with slight friction, a float rod formed of a part 17 of high permeability magnetic metal or alloy which is secured, e.g. by screwing 19, to a part 18 made of non- magnetic material, e.g. brass. The casing 11, open to the outside and sealed within an opening in a side wall of a container 10 by screws 14, has an internal lining of thermo-plastic insulating material 32 and, as with the pipe 15, is made of non-magnetic material. The coils 22, 23 acting as primary and secondary windings of a transformer, are connected respectively by conductors 24, 25 and 26, 27 to a low voltage source of alternating current 29 and an amplifier relay 30 designed to control a warning, pump, or valve circuit, not shown. When the float rod 17, 18 is raised sufficiently, in response to a rise in the level of liquid 20 in the container 10, the high-permeability part 17 of the rod increases the mutual conductance between the coils 22, 23 and a voltage of corresponding magnitude is induced in the secondary winding 23 to operate the relay 30. The device may be mounted in the lower part, to limit the draining of a container, the parts 17, 18 of the rod in this case being made respectively of non-magnetic and magnetic material. Alternatively the float 20 and its rod 17, 18 as shown could be arranged above the casing 11. In the case of a container having a moving cover the casing 11 is provided with a chimney which carries the electric wires 24- 27 and passes in a liquid-tight manner through the cover. When a moving roof can act as a float the lower end of the rod 17, 18 rests upon the upper face of the roof. The chimney may pass through a stuffing box in the cover and be graduated to enable the height of the casing 11 in the container to be adjusted as required. The casing may contain three windings, one primary and two secondaries, preferably arranged in opposition to actuate a differential relay.

Title: Packaging of cheese
IPC: A23C19/14
Filed: 1955-06-15
Abstract: The curing of cheeses which can be cured in the absence of air, e.g. Swiss and American Cheddar types, is effected by storing the cheese at an appropriate temperature in a gas-tight container in which the initial oxygen concentration exceeds that for development of visible mould, the amount of cheese in relation to the amount of oxygen being such that the oxygen is utilized to a concentration at which mould will not grow in a period less than that necessary for visible mould to appear.  The amount of cheese should be sufficient to reduce the oxygen level to below 0,5 per cent by volume for Swiss type cheese or below 5,0 per cent for Cheddar type cheese for holding periods equivalent to less than 3 days at 65 DEG F., e.g. less than 5 days at 55 DEG F. and less than 7 days at 45 DEG F.  For 60-day old Cheddar type and Swiss type cheeses cured at 45 DEG F., a ratio of at least 0,4 g. of cheese per ml. of air is suitable.  The surface area of the cheese to be stored may be increased by preliminary reduction of its particle size.  Cheese packaged in accordance with the method has a greatly extended shelf life.  The method may be practised at any stage after the curd is made, in order to allow flavour development without mould growth, e.g. the curd may be aged in drums.
