Patent GB-1256631-A (GB)
IPC: H04N21/2365
Filed: 1969-07-08
Abstract: 1,256,631. Facsimile line transmission. INTERNATIONAL BUSINESS MACHINES CORP. 8 July, 1969 [12 July, 1968], No. 34268/69. Heading H4F. Simultaneous transmission of pictures having two different levels of brightness e.g. black letters on white paper, between a plurality of scanning and receiver stations by way of a single transmission line (or channel) 13, Fig. 1, is effected by applying the respective video signals comprising positive " 1 " signals corresponding to samples below a predetermined threshold, i.e. black picture elements, along input lines 11 to a coder and multiplexer 12. For each " 1 " signal to be transmitted a binary coded address of an associated receiver station is transmitted instead of the " 1 " signal itself. The address signals are decoded in the address decoder 14 and conveyed to the corresponding receiver station in the form of a single " 1 " signal. Since only one address signal may be transmitted during a scanning interval a priority control circuit (described with reference to Figs. 3 and 4, not shown) is included in multiplexer 12 which selects one signal for transmission when more than one video signal is received by the multiplexer simultaneously. As described a predetermined fixed allocation for each scanning station to only one receiver is assumed i.e. signals from scanner 10-1 are always transmitted to receiver 16-1, although with more complex exchange circuitry interchangeable connections would be possible. All the cameras and receivers are operated in synchronism, a frame scan start signal 17 being transmitted along the line 13. To improve picture quality the assigned priorities for the scanner signals are preferably alternated since with a fixed priority assignment if two scanners scan two black horizontal lines simultaneously one receiver would display the undistorted signal sequence 111111 &c. whereas the other receiver would receive the sequence 000000 &c. i.e., the line would be missing. With alternating priority the receivers would receive the sequences 101010 and 010101 with corresponding improved picture quality. Instead of just alternating the priorities the priority control circuit may be controlled by pseudo-random pulse sequences. In addition the elements of each picture may be scanned in pseudo-random sequence (Figs. 6a and 6b, not shown), the elements of the corresponding picture at the receiver being built up synchronously in the same sequence. Different scanning sequences may be used for the pictures, or the same scanning sequences may be employed but displaced with respect to one another in time. To transmit pictures having a plurality of brightness- or grey-levels only those signals derived from picture elements having a defined grey-level are transmitted during one frame scan i.e. the required number of frame scans correspond to the number of grey-levels to be distinguished.

Abstract: 1290520 Automatic gain control S KUDELSKI 23 Dec 1969 [26 Dec 1968] 62710/69 Heading H4R In an automatic gain control circuit the rate at which the gain increases in response to a decrease in output signal level is increased when the output signal level has been below a predetermined level:for more than a predetermined time. As described a variable impedance network 10 controls the signal applied to an amplifier 11 in dependence on a control signal derived from the amplifier output by a full wave rectifier circuit including transistors T1 and T2, fed with antiphase amplifier output signals which charge a capacitor C1, the voltage across which controls the impedance of the network 10. The capacitor C1 has a first discharge path R1 and second discharge path including R3 and transistor T4 which is normally non- conductive, rendering the discharge path inoperative, but is rendered conductive, to lower the discharge time of the capacitor C1, when the signal level has been below a predetermined level for more than a predetermined time. Transistor T4 is normally held non-conductive by the conduction of transistor T3 in response to the signal from amplifier 11 applied to its base. When the amplifier output level falls transistor T3 ceases to conduct allowing capacitor C2 to charge and, after a predetermined time, turns on transistor T4. The variable impedance network as shown in Fig. 3, includes a diode bridge 21 as a variable shunt impedance to earth from the signal path between terminals 23 and 24 with the D.C. control current for the bridge derived from a circuit including a logarithmic network 29 to provide a variation of gain following a logarithmic law relative the control voltage at terminal 25.

Abstract: 1339199 Texturizing protein material GENERAL MILLS Inc 26 July 1971 [27 July 1970] 35023/71 Heading C3H [Also in Divisions A2 and B1] The texturizing of particulate protein material, in which the material is contacted in a texturizing zone with a heated gaseous fluid at a fluid pressure of at least 15 p.s.i.g. for a time sufficient to provide the desired texturizing effect, may be carried out by propelling the particles from a pocket 41, see Fig. 5, of a rotary valve 12, see Fig. 1, by means of superheated steam from a line 26 into tube 14 and out through nozzle 59 into the atmosphere against the back pressure in concentric surge tank 13. In an alternative embodiment (Fig. 7, not shown), the surge tank consists of a small compartment (66) surrounding the tube (14A) and at some distance a larger compartment (67) connected to it by piping. In yet a further embodiment (Fig. 8, not shown), back pressure is produced by injecting water under pressure into tube (14B) through a line (71). The rotational sequence (clockwise) of the rotary valve is depicted in Figs. 4 to 6. Line 27 serves to depressurize the pocket prior to refilling. There may be 4, 6 or 8 pockets in the valve member. Examples are directed to texturizing the following protein materials in particulate form; say protein isolate; blended soybean concentrate and soy protein isolate with, optionally, glycerol monostearate and caramel colour; blended soybean concentrate, soy protein isolate, sugar, onion powder, caramel, hydrolysed protein flavouring (beef flavour) and red colouring; soy bean flour, glycerol monostearate and caramel; soy bean flour and wheat flour; defatted cottonseed flour alone or mixed with soy protein isolate; gluten; yeast flour; and sodium caseinate. The texturized protein material may be impregnated with meat analog serum including binder, flavouring and water, to produce a simulated beef or chicken chunk. The protein material may be ground, hydrated and mixed with ground beef or pork sausage, thus acting as a meat extender. A simulated ground beef may be prepared by mixing the protein material with beef tallow, corn flour, egg albumin, brown sugar, onion powder, salt, beef flavouring and caramel colouring, and heating to set the egg albumin.
