Title: Feed control system
IPC: B41J11/44
Filed: 1968-05-24
Abstract: 1,207,032. Selective signalling. R.C.A. CORPORATION. 24 May, 1968 [29 June, 1967], No. 24835/68. Heading G4H. A printer, Fig. 1, in which the paper feed is controlled by one of a plurality of programmes punched in a photo-electrically read tape loop 58, is characterized in that a plurality (eight) of rows of the loop are recorded in image form in a high speed store, whereby when paper feeding has to take place the control circuit can " look ahead " and if the paper has to be moved a sufficient number of lines (e.g. more than nine lines) the drive can be at high speed reverting to low speed just before the desired position is reached. Each track on the programme loop of tape, Fig. 2, relates to a different programme, and the holes are punched in row positions corresponding to lines on the paper in which printing is to occur. Thus, in the example shown, programme No. 4 will cause the paper to stop at lines N+2, and N+3. In prior arrangements, the position of the programme loop read station corresponds to the line of paper under the print hammer-the " print line "- and paper feeding continued until a hole was sensed in the operative programme. In the present arrangement, the programme loop read station is positioned eight rows in advance of the print line, and an image of the intervening eight rows of the programme loop is retained in a high speed core store arranged so that the eight bits relating to any one of the twelve programmes on the programme loop can be addressed by a single number. For example, as shown, address 84 in the store corresponds to programme No. 4 on the loop. As the rows on the programme loop are successively read, when paper feed is occurring, the data in the core store is successively shifted to the right so that nine rows. of the programme loop (the one currently being read, and the eight in the core store) are always available fcr use in determining the speed of paper feeding. The control circuit for updating the core store as successive rows of the programme loop are read is shown in Fig. 3. When a row is read 62, Fig. 3, it is entered into a buffer 102 under the control of clock-pulses derived from a photo-electrically sensed disc 42, Figs. 1, 3. Under the control of relatively high frequency clock-pulses 110, Fig. 3, the eight bits (plus possibly a ninth parity bit) in address position 81 of the core store 100 are read into a shift register 172. This register is then shifted to the right taking in one bit from the buffer 102 at the left and losing one bit at the right. The result is then read back to the main core store 100 and updating of address No. 81 is complete. A similar operation is performed for the remaining eleven addresses in the store 100. Control of paper feed speed is effected by logic 174, Fig. 3 (Fig. 4, not shown), which, when that row of the main store 100 that corresponds to the particular programme exercising control has been transferred to the shift register, has available to it nine bits of the programme from which the appropriate speed can be determined.

Title: Single handle mixing valve
IPC: F16K11/078
Filed: 1973-05-25
Abstract: 1402077 Valves SYMMONS INDUSTRIES Inc 25 May 1973 [30 May 1972] 25084/73 Heading F2V A mixing valve for hot and cold water comprises a valve plate 92 sandwiched between a pair of ceramic valve seats 62, 64, the valve plate carrying a pair of ceramic discs (96, 98) (Fig. 7, not shown) with apertures 124 offset from each other and which communicate with passages (108a, 108b, 108c) in the valve plate to allow hot and cold water to pass from their inlet chambers 132, 134 respectively, through their valve seats 62, 64 to a mixing chamber 136 and thence to outlet 36, the valve plate being movable by stem 162 linearly to control the total quantity of water discharged and pivotally to control the proportion of hot water to cold. A guide pin 170 having a flat head co-operates with a channel 176 in the valve operating member 158, 162 to constrain the movement of the stem to and away from the outlet 36 producing the linear movement of the valve plate; but the guide pin may also rotate in its bore 166 to give a rocking motion to the plate. Figure 90 shows in bold lines the plate 96 lifted and rocked to one side to allow only hot water to pass from the valve seat bore 63 through the aperture 124 to the mixing chamber. Progressive rotation of the valve operating stem gives proportionately more cold water until finally only cold water flows to the mixing chamber. If the valve plate is fully lowered, as shown in dotted lines, it remains in the "off" position no matter how the operating member is rotated. An adjustable stop 193 is provided to limit the maximum opening for hot water. The guide pin may be replaced by slotted ring (182A) (Figs. 12, 13, not shown). A spring (230) (Fig. 14, not shown) may be introduced as a throttling device to reduce noise. The valve discs 96, 98 may be made integral with each other.

Title: Color killer and acc circuits
IPC: H04N9/71
Filed: 1969-05-19
Abstract: 1,272,634. Colour television. RCA CORPORATION. 19 May, 1969 [22 May, 1968], No. 25374/69. Heading H4F. In a colour television receiver a common automatic chroma control and colour killer circuit comprises an amplifier circuit, coupled to the receiver's burst amplitude detector, which operates in two modes i.e. in the ACC mode in which the gain of the receiver's chrominance amplifier is controlled when the amplitude of the burst signal is above a certain level, and in the colour killer mode in which the chrominance amplifier is rendered inoperative when the burst amplitude is below this level. In a first embodiment, Fig. 1, the base of transistor 50 is coupled to the output terminal of the burst amplitude detector. In operation  for a first range of burst detector output voltages (zero or low amplitude bursts), the base-collector junction of transistor 51 remains reverse biased, and transistors 50, 51 provide a high gain twostage D.C. amplifier for kill/unkill control of the bandpass amplifier 23. When the burst amplitude rises sufficiently to forward bias the base collector junction of transistor 51, transistor action is lost in transistor 51 with a consequent reduction in gain at the D.C. amplifier for killer control purposes. For the range of detector output voltage above that which produces forward biasing of the base-collector junction of transistor 51, the voltage at the collector of transistor 51 directly follows (without polarity inversion) the changes at the collector of transistor 50. These followed changes are applied to the chrominance amplifier 22 to adjust its gain for automatic chroma control purposes. Increase in burst amplitude produces a gain reduction in the amplifier 22. In a second embodiment, Fig. 3, in which independent ACC threshold adjustment is possible according to the magnitude of resistors 66 and 67. Further, the level at which the mode shift takes place is determined independently of threshold determination for initiation of ACC action. This level is determined by voltage divider 64, 68 which biases the cathode of diode 63, the mode shift taking place when the burst detector output level rises sufficiently to forward bias the diode 63. The bursts are eliminated from the demodulator channel by gating the bandpass amplifier 23 with deflection pulses Diode 63 may be replaced by a transistor (Fig. 4, not shown).
