Title: Memory cell
IPC: G11C11/402
Filed: 1968-12-11
Abstract: 1,224,937. Transistor bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORP. 11 Dec., 1968 [15 Jan., 1968], No. 58872/68. Heading H3T. [Also in Division G4] A memory cell comprises a pair of crosscoupled FETs forming a bi-stable circuit, in which the OFF transistor provides a backward biased PN junction in the leakage path between its substrate and the gate electrode of the ON FET. A pair of backward biased PN junction devices are connected to the gate electrode of each FET, having a higher leakage current than the PN junction of the OFF FET. In Fig. 1A the READ and WRITE operations are as described for Specification 1,224,936. However, the charge on the ON FET gate of the bi-stable circuit is maintained during the quiescent period by means of a leakage current path existing, e.g. via the biased substrate 39 and region 16 of the switching FET 14 through region 11 and substrate 8 of OFF FET 3. The resistance of the reverse biased PN junction of the FET 14 is deliberately made much lower than that of FET 3, Figs. 1B, 1C (not shown), such that a voltage of approximately -VS exists at the gate 12 of the ON FET 2 thus maintaining its charge. The leakage path via the other FETs 13 and 2 ensures that FET 3 is kept OFF by maintaining a substantially zero voltage at its gate. The transconductance (gm) of the storage FETs is made greater than that of the switching FETs so that during READ out, the high voltage existing across the switching FET keeps the gate voltage of the OFF FET below threshold value.

Patent GB-670216-A (GB)
Abstract: 670,216. Labelling-machines. CROWN CORK CO., Ltd. Sept. 1, 1950 [Sept. 5, 1949], No. 22932/49. Class 73. A labelling-machine has two arms mounting suction pads which detach a label from a pile pass it through a pair of gumming rollers and apply it to a bottle mounted on a stationary support. Suction pads 20, 21, Fig. 2, are mounted on arms 18, 19 which are separately rotatable about a spindle 25, Fig. 4, which is itself rotatable in a crosshead 16 of a piston rod 15, by engagement of a pinion 26 with a rack 27. The arms 18, 19 are fixed on bosses 33, 34 rotatable on the spindle 25 to allow separation of the pads. The bosses are urged by springs attached to pins 51, 54 to keep the pads together but are also engaged by fixed clutching devices. The clutching devices comprise a ring 35 and a block 36, prevented from rotation relative to the spindle 25 by cotters 37, 38 which extend through slots into a rod 28, which have frictional engagement through rubber rings 42 with the bosses 33, 34. The end of the rod 28 has a thimble 29 extending beyond the spindle 25 and kept in contact with fixed cams 30 and 31 (not shown) on a column 12 by a spring 32. Pins 45, 46 attached to links 47 extend into opposite sides of an arcuate slot 44 concentric with the axis of the spindle 25 in the block 36 to limit the spreading apart of the arms 18, 19. The initial spread of the arms is adjusted and the movement of the arms altered by moving the position of pins 48 also on the links 47 in slots in the bosses 33, 34. In operation at the top position, shown in solid lines Fig. 2 and in Fig. 4, the pads 20, 21 extract a label from a carrier 17 and the piston rod 15 moves down the pads turning through 180 degrees before passing between gumming rollers 23. On reaching a bottle placed on a rest 24 to apply the gummed label the pads spread out and wipe on the label but are prevented from closing under their spring action and thus disturbing the applied label by a cam engaging with the thimble 29 to operate the clutching device. As the piston returns the thimble 29 moves off the cam for a period to allow the pads to close under their spring action before a further cam again engages the clutching device to hold the arms in their closed position against the centrifugal force as the spindle 25 turns on the upward and downward movement of the piston 15. A modified clutching device has spring pressed pawls in the bosses 33, 34 which engage serrated surfaces on the fixed clutch parts. Suction is applied to the pads from passages through the spindle 25 and bosses 33, 34 which are connected to the piston rod 15 which is hollow.

Title: Television horizontal oscillator frequency control arrangement
IPC: H04N5/95
Filed: 1978-12-14
Abstract: A television receiver used in conjunction with a video tape recorder is liable to receive a step change in phase of the horizontal synchronizing pulse occurring prior to the vertical blanking signal and this can produce a distorted video display. The unwanted video distortion results from too slow slewing of the horizontal oscillator phase-locked loop to the new phase. By the invention, to reduce the video distortion, the low- pass filter 40 in a phase locked loop including a phase comparator 20, a horizontal oscillator 50, deflection circuit 52 and integrater 56 is switched to a high gain condition at a time before the end of the vertical scanning interval. Such switching can be accomplished by a monostable multi-vibrator 71, 72 or a threshold arrangement (Figure 3). The invention is not prejudicial and does not require any switching out of the inventive components, when line pulses not liable to said unwanted phase discontinuities are being received, e.g. from conventional received transmissions. <IMAGE>
