Title: Tunnel diode sense amplifiers
IPC: H03K17/58
Filed: 1962-08-08
Abstract: 944,791. Tunnel diode bi-stable circuits. NATIONAL CASH REGISTER CO. Aug. 8, 1962 [Dec. 8, 1961], No. 30350/62. Heading H3T. A tunnel diode bi-stable circuit comprising a constant current source and two similar branches, each comprising a series connected resistor and tunnel diode, connected in parallel thereacross, is arranged so that when an input signal is coupled to the two branches in opposite senses and the two branches are both in their low impedance states, one or other of the branches is switched to its high impedance state. As shown in Fig. 1 a sense signal induced in the sense winding 10 threading a plurality of memory elements is applied to points 13, 14 of two parallel branches respectively comprising tunnel diodes 15, 16 and resistors 19 connected across a substantially constant current source provided by resistor 17 and negative supply -Vc. Initially both tunnel diodes are in their low impedance state, Fig. 2 (not shown), but when a sense signal is applied at 13, 14 such that these points have opposite polarity input signals applied thereto, one or other of the diodes is switched to its high impedance state. The output may be taken from the common junction between diodes 15, 16 and the diode which has been switched may be reset for the next cycle of operation by reset pulse VR applied to junction 12, the pulse being applied during all of the read-write cycle of the memory array except at that time when a sense signal is to be received by the tunnel diodes, Fig. 5 (not shown). In the embodiment of Fig. 3 (not shown) the reset pulse is applied to the common junction of the two opposed tunnel diodes by replacing resistor 17 of Fig. 1 with a resistor arrangement and an NPN transistor to the base of which are applied reset pulses: In the circuit of Fig. 4 the sense signal from sense line 30 is applied to the bases of a pair of NPN transistors 32 forming a differential amplifier and thus modulates the current supplied to the tunnel diodes. The operation of this circuit is substantially the same as that of Fig. 1 but the detection of the change of state of the respective tunnel diode is made at junctions 43, 44 by an OR circuit comprising two emitter coupled PNP transistors 37 which convert the tunnel diode output signals to the proper logic level of the computer component receiving the output signal. The circuits of Figs. 1, 3, 4 act as noise discriminators in that the diodes are only switched when the input signal is above a predetermined signal level.

Patent GB-751747-A (GB)
Title: Apparatus for printing or similarly treating sheets
IPC: B41F31/32
Filed: 1953-11-04
Abstract: <PICT:0751747/III/1> Apparatus for coating paper or like material in the form of sheets comprises a single control mechanism adapted to cause the throwing-off, from the other roller, of one of a pair of rollers which normally cooperate to coat the material, whilst simultaneously throwing off the liquid transfer roller from the thrown-of coating roller but leaving it in running contact with the feed source of liquid medium, the control mechanism comprising at least two eccentrics operable by a single control spindle or member so that one of the eccentrics will cause the coating roller to be thrown off its co-operating roller, and the other eccentric will cause the throwing-off of the transfer roller from the coating roller.  The printing roller 17 is mounted on a shaft 10 carried on two arms 8 pivoted on a shaft 4 which is provided with an eccentric 5 and an eccentric 6 at each end.  The pressure of the roller 17 against the impression roller 18 is adjustable by a knob 24 and screwed rod 22.  The eccentrics 5 constitute bearings for the arms 8, and rotation by a hand wheel of the shaft 4 causes the roller 17 to be moved out of contact with the roller 18.  The shaft 10 is adjustable axially by a screwed rod.  A duct roller 28 rotates in a trough 3 of aniline ink.  The inking roller 29 is mounted on a shaft 32 carried on arms 33 pivoted on a shaft 34 mounted between rocking plates 31 pivoted on the shaft 30 carrying the roller 28, so that the roller 29 rests by gravity on the roller 28 with a pressure adjustable by a knob 39 on a spindle 37 bearing against a part 36 of a collar on the shaft 32.  The eccentrics 6 are encircled by straps 40, having arms 41 connected by screwed rods 42 to brackets 46 on the plates 31, whereby rotation of the shaft 4 to trip the roller 17 at the same time trips the roller 29 away from the roller 17, while leaving it in running contact with the roller 28.  Knobs 44 adjust the position of roller 29 with respect to the eccentrics 6 to compensate for any alteration in the position of the roller 17.

Abstract: Spraying-apparatus for painting, varnishing, washing, or disinfecting vehicles comprises a bridge-like structure, into which the vehicle can pass, with spraying units disposed on the structure so as to extend up beside the sides and across the roof of the vehicle, and means for adjusting the units in substantially parallel relation to the said sides and roof.  The unit for spraying the roof may be adapted for spraying the ends also of the vehicle.  Fig. 1 shows uprights 2 carrying sets of spraying nozzles 3 vertically adjustable by means of cables and counterbalance weights, and transversely adjustable, equally and simultaneously, for different widths of vehicles, by means of parallelogram linkage 38 on which they are mounted.  The vertically movable beam 8 carries nozzles for spraying the vehicle roof 7, the nozzles 6 being mounted on supports 10 which are pivoted at 11 so that they can be adjusted to conform with the profile of the roof.  For spraying the ends of the vehicle, the members 10 are brought into alignment with the beam 8, which is then bodily turned about its longitudinal axis until its jets deliver <PICT:0446273/III/1> <PICT:0446273/III/2> an inwardly directed spray, the beam then being moved up and down past the vehicle end.  The valves 55 of the nozzles 3 can be opened and closed singly and successively by vertically slidable cam-bars 57, and by this means the number of nozzles suitable for the depth of side to be painted can be opened as required.  When the apparatus is used for washing vehicles, an additional spraying member may be provided, operating from below the body of the vehicle.  The various movable parts may be operated by electric motors, controlled from a cabin containing paint stores and air-compressing plant.
