Title: Improvements in and relating to multistable switching circuits
Inventor: TODD ROBERT JOHN
IPC: H03K3/29
Filed: 1962-12-14
Abstract: 1,061,404. Electronic counters. SPECTO Ltd. Nov. 21, 1963 [Dec. 14, 1962], No. 47260/62. Heading G4A. [Also in Division H3] A multistable-state circuit comprises three or more two-state switching stages such as transistors VT1, VT2, VT3, arranged by means of a first group of couplings made respectively between each of said stages and each of the respective remaining stages so that one stage assumes a first switching state and all the remaining stages assume the opposite switching state, there being further provided a second group of couplings whereby there is supplied from whichever stage is in said first switching state an inhibiting signal which is applied to each stage (including the stage in said first state) except the next stage in operation sequence thereto whereby only said next stage is able to respond to the next triggering pulse applied in common to all said stages to cause said next stage to assume the first switching state and thereby cause whichever stage had previously assumed said first state to assume said opposite state. In the circuit illustrated, f transistor VT1 is non-conducting the potential of + 8 volts at its collector established by catching diode MR1 is applied through resistors R2, R3 to the bases of transistors VT2, VT3 whereby thse transistors are rendered fully conducting. Corresponding voltages fed back from the collectors of transistors VT2, VT3 through resistors R5, R6 to the base of transistor VT1 maintain that transistor cut off. There is further supplied from the collector of transistor VT1 potentials of approximately +4 volts to the lower electrodes of capacitors C1 and C3 via potential dividers R7, R8 and R11, R12 respectively. Diodes MR2, MR4 are consequently heavily reverse biased. The potential applied to the lower electrode of capacitor C2, however, is in the region of zero volts since potential divider R9, R10 is connected between the collectors of conducting transistors VT2, VT3. Diode MR3 is consequently not reverse biased so that a negative trigger pulse applied in common to capacitors C1, C2, and C3 will be applied to the base of transistor VT2 with greater amplitude than to the other transisters. Transistor VT2 is consequently rendered non-conducting and due to the couplings from its collector to the bases of transistors VT1, VT3, transistor VT1 is made to conduct and transistor VT3 remains conducting. A subsequent trigger pulse causes transistor VT3 to be cut off and restores the conducting condition to transistor VT2 and so on.

Abstract: 952,159. Wire changing in paper machines. DOMINION ENGINEERING WORKS Ltd. Dec. 19, 1962 [Jan. 26, 1962], No. 47979/62. Heading D2A. To facilitate the changing of the wire cloth of a Fourdrinier-type paper-making machine the breast roll is mounted on swinging arms which are pivoted to swing in the horizontal plane in order to retract the breast roll, and thus to slacken the wire cloth. Swinging arms 19 are pivoted by pins 20 to brackets 21 attached to the ends of main beams 22 disposed at either side of the Fourdrinier machine and the arms 19 carry, at their outer ends, intermediate arms 12 which are pivotally attached thereto by pins 18. The intermediate arms 12 carry the bearing housings 11 for a breast roll 10 and in the normal working position overlie the swinging arms 19 and are bolted thereto by bolts 29. A forming board 17 passes across the width of and beneath the wire cloth and is bolted rigidly to the intermediate arms 12. Pins 20 are prevented from rotating in the brackets 21 by dowels 23 and a drive motor 25, flange-mounted on one of the arms 19, has its shaft keyed to the pins 20 so that operation of the motor causes the swinging arm to move around the pin 20. To retract the breast roll for wire-changing, bolts 29 are released, support wedges 30 mounted in support stands 31 are withdrawn and motor 25 is energized to move the breast roll to the retracted position. The parallel relationship of the intermediate arms 12 is maintained during the swing- ing movement of arms 19 due to the rigid attachment thereto of both the forming board and breast roll and thus also the two arms 19 move in unison. Fixed stops 28 on swinging arms 19 limit the return travel of the intermediate arms and ensure that the breast roll takes up its correct working position. The breast roll 10 is provided with a limited measure of vertical and longitudinal adjustment by means of screws 15,16 and wedge 14 and a doctor blade 27 is provided against the breast roll.

Abstract: 1308359 Etching FAIRCHILD CAMERA & INSTRUMENT CORP 14 Oct 1970 [31 Oct 1969] 48844/70 Heading B6J [Also in Division H1] In an integrated circuit comprising several mutually insulated superposed metal interconnection layers on a semi-conductor substrate the interconnections in all save the uppermost layer have sloping sides and ends which blend gradually into their upper surfaces so to avoid sudden changes in elevation of subsequently deposited insulating and interconnecting layers. Standard techniques are employed in the manufacture except that the etchant used in patterning deposited metal to form the interconnections is selected so that it gradually undermines the photoresist masking pattern during etching to appropriately contour the interconnections. In the embodiment where the metal is aluminium or aluminium-silicon alloy (less than 2% silicon) a mixture of, by volume, 20% concentrated acetic, 20% concentrated nitric and 60% concentrated prosphoric acids is used as etchant at 85 C. The effect of varying the composition and temperature of the acid is discussed.

Title: Improvements in or relating to analogue voltage storage apparatus

Filed: 1966-11-02
Abstract: 1,206,934. Analogue storage circuit. MINISTER OF TECHNOLOGY. 31 Oct., 1967 [2 Nov., 1966], No. 49091/66. Heading H3T. An analogue voltage is stored on a capacitor by writing pulses from a low-impedance source applied through a transistor connected to the input and the capacitor via respective unilaterally conducting devices, and is read out by means of pulses from a high-impedance source connected to the capacitor and to an output circuit via respective further unilaterally conductive devices. In Fig. 2 an analogue voltage at V in  is transferred to the capacitor C1 by an enabling pulse on transistor Q4 which turns on Q3 and allows diodes D1 and D2 to conduct. The duration of the enabling pulse should be very much greater than the time-constant C1R1, and the latter should be less than the period of any variations in V in . To read out, a positive pulse is applied to the top of R2 so that diodes D3 and D4 and transistor Q2 are turned on and the voltage on C1 is transferred to V out . The duration of the read-out pulse should be much less than the time-constant of C1R2 (so that the read-out will be non-destructive), but longer than COR2 where CO is the stray capacitance between the base of Q2 and earth. This capacitance is discharged through diodes D6 and D7 and transistor Q6 by turning on the latter immediately before read out. The above circuit may be arranged in multiple to form a matrix, with transistor Q1 and resistor R3 common to all the circuits. Those in one row may be activated in succession by applying a long enabling pulse to transistor Q5 and a succession of shorter pulses to Q4, thus sampling V in  at different instants in time. The bases of Q4 and Q5 in several rows may each be connected to a single stage of two separate ring counters (not shown), one selecting a row and the other a particular circuit in a row. Transistor Q2 may similarly be common to a row of circuits, read-out being enabled by a long positive pulse on the collector of Q2. This and R2 may be connected to ring counters as for Q4 and Q5. To maintain the voltage on C1 for a long time, the read-out voltage may be applied to a voltmeter having an output connected to a digital-to-analogue converter and the next highest voltage step impressed on C1. Transistors of opposite conductivity types may be used, with reversal of polarities of the diodes and supplies. Q2 may be a cathode-follower valve. The arrangement may be used to store information obtained during the ultrasonic testing of metallic objects.

A telescopic umbrella having telescopic ribs 5, 6, a main slider 11 lockable to the stick 1, 2, main struts 9 pivoted to the rib parts 6 and to the main slider, an auxiliary slider 15, auxiliary struts 12 pivoted to the main struts and to the auxiliary slider 15 to which a spring-loaded catch is connected, the catch, during initial opening of the umbrella canopy, temporarily engaging a slot 27 in the stick wall to arrest movement of the auxiliary slider and consisting of a two-armed lever 20 having a nose 22 retained in the slot 27 to produce a torque transmitted by the shoulder 24 to an auxiliary strut 12 to swing the strut to a splayed position so that the ribs do not telescope. The heads 18 of the auxiliary struts 12 are pivoted in recesses 19 in the auxiliary slider 15 by a wire 16, the lever 20 being mounted between two adjacent struts and having a nose 22 to engage the slot 27, a slot 21 in which the wire 16 is engaged, and a hook 23 engaged by a spring ring 25 so as to tend to rotate the lever anti-clockwise but is unable to do so when the strut 12 is parallel to the stick. On arrest of the slider, in opening the umbrella canopy, torque in the lever arm a is transmitted by the lever arm b and abutment by the shoulder 24 swings the strut away from the stick. In closing the canopy the inclined surface 28 slides along the edge of the slot and during telescoping of the stick the presence of the part 2 of the stick behind the slot 27 prevents arrest of the auxiliary slider. In a modification the lever is mounted on the auxiliary strut by a pivot pin remote from the pivotal connection of the strut to the auxiliary slider and a bent wire spring tends to bring the nose of the catch into the slot in the stick. In a further modification, shown in Fig. 10, a spring bar 40 is clamped by notches 41 within one or more of the channel-section auxiliary struts 12a and tends to spring towards the stick axis, the head 42 having a nose 45 engaging a slot 49 in the stick and a slot 43 in which the pivot pin 44 slides. The axis of the torque produced when the edge 46 engages the top of the slot 49 is coincident with the pivot 44 and splays the auxiliary strut 12a until the nose is released from the strut. The head 42 may be riveted to the bar 40 and guides for the catch may be provided. Specification 804,619 is referred to.
