Title: Record mode release mechanism
IPC: G11B15/675
Filed: 1972-11-28
Abstract: 1356900 Cassette players/recorders; control of operating function MOTOROLA Inc 28 Nov 1972 [6 Dec 1971] 54916/72 Heading G5R A cassette player/recorder includes a function selector 42 which is automatically released from a record position when, in removing the cassette, an actuator bar 16 is depressed as at 28 to move a cassette-receiving carriage 12 to an inoperative position. A first depression of the bar 16 by knob 26 lowers the cassette on to drive spindles (not shown), and a second depression raises it therefrom. The function selector comprises a shaft 44 and knob 50 rotatable between playback and recordready positions to drive through gears 52, 58 a rotary switch 54 which makes the requisite electrical connections. When in the recordready position, the knob 50 must be depressed as at 100 to reach the record position. In the playback and record positions a cam 60 on the shaft 44 engages a projection 70, Fig. 5, of an interlock arm 66, to pivot the arm 66 out of the path of a projection 84 on the actuator bar 16 and permit depression thereof to lower the cassette. The selector 42 is retained in the depressed record position against spring bias 53 by a lip 64 on the cam 60 engaging the projection 70. In the record position a switch 92 is also actuated by the cam 60 to enable a cassetteeject circuit, Fig. 7 (not shown), to energize a holding solenoid 94 which prevents the cassette being ejected.  Selector release mechanism.-The interlock arm 66 is caused to pivot, so that the projection 70 releases the cam lip 64, by a lever arm 134, Fig. 2, which is itself caused to pivot as the actuator bar 16 is depressed again to raise the cassette. The bar 16 is linked to an arm 18 in such a way that the arm 18 moves in the opposite direction 36 to the bar 16. A slide 112 is connected to the arm 18 and carries a cam projection 128 on a leaf spring 126 for co-operation with a notch 136 of the lever arm 134. When the bar 16 is depressed upon cassette insertion, the arm 18 and slide 112 move forward as at 124 and projection 128 rides over the lever arm 134 into the notch 136. When the bar 16 is depressed again upon cassette withdrawal, the projection 128 moves rearwardly as at 125 and engages the notch 136 causing the lever arm 134 to pivot and engage the interlock arm 66 to release the function selector. With the selector now in the recordready position and the solenoid circuit deenergized by the switch 92, a cassette cannot be retained in the unit without shifting the selector to the record or playback position.

Filed: 1974-12-23
Abstract: 1472319 Infrared gas analysis apparatus BERGWERKSVERBAND GmbH 23 Dec 1974 [3 Jan 1974] 55487/74 Heading G1A Such apparatus comprises emitter 2 radiating modulated infrared through chamber 3 for receiving the gas to receiver 6 with reception chambers 4, 5 producing by absorption a difference signal representative of concentration, which is compensated for phase and amplitude with respect to such a signal produced in the absence of this gas, by pneumatic pressure generator means as 10, 11 in  chambers pneumatically connected to at least one detector chamber 4, 5. Using a squarewave potential of a few Hz from generator 1, radiator 2, which is a thin heat conductive band, is periodically heated, so that its radiation produces in chambers 4, 5 pressure pulses whose difference is measured by membrane capacitor 7 with amplifier 8 and meter 9. Heater coil 10 is connected to generator 1 by delay circuit 12, 13, 14 so that its signal to chamber 4 lags the signal due to radiation via chamber 3 and its amplitude is such as to compensate for the out of phase component of the difference signal, which is produced by the delay of the signal from chamber 5. The in phase difference signal is compensated by a signal from coil 11 of amplitude controlled by resistors 15, 16. The emitter circuits can include further RC members. Electronic switch circuits can be used instead of RC circuits.  In the embodiment of Fig. 2 (not shown) the measuring signal is transmitted via resistors and a diode to heater 11. These resistors and resistors 15 and 16 have a high resistance compared with heater 11. Alternatively the measuring signals can be applied to an extra emitter, and if its signals are in antiphase to the measuring signal, the amplifier is stabilized.

Title: Closed loop proportional plus integral control system
IPC: G05B11/00
Filed: 1966-12-21
Abstract: 1,148,490. Automatic control. INTERNATIONAL BUSINESS MACHINES CORP. Dec. 21, 1966 [Jan.17, 1966 (5)], No.57205/66. Heading G3R. In a closed-loop proportional plus integral control system, the controlled variable is sampled at one rate and compared with a reference value to produce the proportional component which is sampled at a lower rate and the samples integrated to produce the integral component. In Fig. 1, a plurality of variables of a process 20 are measured by separate transducers 22 the outputs of which are applied in succession by a channel selector 25 to an analogue to digital converter 26. Numbers of pulses corresponding to the magnitude of the variable are produced by a ramp generator in the converter during each sampling period and supplied to a register 28. A group of pulses corresponding in number to the appropriate desired value or set point of the variable being sampled is produced from a recirculating memory store 30 by a read circuit 31 and subtracted from the count in register 28 so that the final content of the latter corresponds in magnitude and sense to the error and is supplied through an adjustable divider 33 as a proportional component of control to a register 36. The error pulses are also sampled at very low adjustable frequency by a switch S 2  and supplied through another adjustable divider 39 to a register 35 in which they update the integral of previous error sampling obtained from memory store 30. The updated integral is stored for future use in memory 30 through write circuit 32 and is also supplied to register 36. The output of register 36 thus represents error plus integral of error which is applied through a digital to analogue converter 40 and channel selector 41 to an amplifier 43 in which it is stored capacitatively for a time sufficient to correct the appropriate variable. The Specification describes in detail suitable programming and gating arrangements which include the following additional features:- (a) Adjustable high and low limit detectors associated with the ramp generator so that indication and/or limitation is effected if the magnitude of the variable or its set point tends to exceed predetermined limits during operation or start-up. (b) Disabling of integration sampling whenever the control signal or its proportional component exceeds predetermined limits. (c) Control of one variable by another and automatic control of the set points. (d) A dummy channel selector position and a manually operated channel selector switch to permit manual adjustment of the set points stored in the memory or manual control of the variables with synchronization of the error signals to permit changeover to automatic control without shock. (e) Alarm indicators and decimal display of error and limit values.

Title: Selective dispensing apparatus for bottled products or the like
IPC: G07F11/16
Filed: 1972-12-13
Abstract: 1378416 Dispensing articles VENDO CO 13 Dec 1972 [18 Aug 1972] 57499/72 Heading A4T Dispensing apparatus e.g. for bottled beverages comprises at least one station 32 from which bottles 30 may be released, means 34 for holding a leading bottle 30' against release, means for moving the holding means 34 to allow release, and means 38-56 for locking the means against such movement unless a signal corresponding e.g. to the insertion of an appropriate coin has been generated. Preferably a series of stations 32 is provided, grouped to dispense bottles at two different price levels. On turning a chosen knob 22, a shaft 92 tends to turn the respective means 34 through a pin and groove connection 96, 98, urged by a spring 100. The member 34 includes a portion 86 for engaging the bottle 30' and a portion 124 of a cam 35 engaging within cut outs 118, (120) of adjacent links of a slidably supported link assembly 38 see Fig. 5 (not shown). The cam 35 also includes a pin 140 for location in a cut-out 142 of a price control bar 140 see Fig. 5 (not shown), thus preventing movement of the portion 86 when the bar 140 is locked against rotation. Operation: On insertion of the required coin into a coin-freed mechanism (not shown), a signal is passed to a solenoid 44, Fig. 3, causing retraction of a slidably supported bar 48 to withdraw a locking member 50 from engagement in a recess 148 of the control bar 40, allowing the chosen knob 22 to be turned. Movement under the action of the cam 35 of those links of the assembly 38 to the left of the actuated cam 35 as shown in Fig. 2 causes studs 122 on the links to engage portions 130 of the corresponding cams 35 of the other stations 32, thus preventing simultaneous dispensing from such stations, the stations to the right (as shown) being blocked by engagement of the rotated cam 35 with the adjacent stud 122 to prevent movement of the links to the left. Turning of the portion 86 allows the leading bottle 30' to leave its position on a storage rail assembly 62 under gravity, a secondary retaining element 36 being pivotally actuated by camming means to prevent the next bottle 30 from advancing until the portion 86 has returned to its initial position. A further control bar 42 is associated with some of the stations 32 for vending bottles at a different price, this bar 42 being associated with locking means 54 actuated by a further solenoid 46 to allow dispensing only when the bar 42 is free to move. A slidable bar 52 for unlocking the bar 42 is connected to the bar 48 for actuating the locking member 50 of the first-mentioned control bar 40, so that on freeing the bar 42, the bar 40 is also unlocked.

Title: Improvements in or relating to pulse operated control devices for series wound direct current electric motors
Inventor: WRIGHT JAMES
IPC: H02P7/29
Filed: 1968-12-11
Abstract: 1,242,130. Control of D.C. motors. CONVEYANCER FORK TRUCKS Ltd. 11 March, 1970 [11 Dec., 1968], No. 58781/68. Heading H2J. A D.C. series-motor is supplied with pulses, the motor current flow being maintained during inter-pulse periods, and means are provided for interrupting the current-flow during a part of each inter-pulse period. When a positive feed is applied to switch 4, rectifiers SCR1, SCR2, are switched-on whereby capacitors C1, C3, are charged, while transistor TR1 conducts to charge capacitor C2. When the current through coil 3, field winding 1, armature 2, and rectifier SCR1 reaches a limiting value, the coil 3 responds to change-over the switch 4. Gating signals are removed from rectifiers SCR1, SCR2, and applied to rectifier SCR3, capacitor C1 discharging through rectifier SCR3.to turn-off the rectifier SCR1. The inductive effect of the motor re-charges the capacitor C1 reversely, while capacitor C2 discharges through coil 2, field winding 1, armature 2, resistor R1 and diode D2, and recharges with reversed polarity. The rectifier SCR4 is switched-on, when its gate-potential becomes sufficient, to conduct the motor circulating current. As the circulating current decreases, coil 3 responds to return the switch 4, the gate signal to rectifier SCR3 being removed, and rectifiers SCR1, SCR2, being switched-on again. Rectifier SCR4 is switched-off while capacitor C2 discharges at least in part through components R4, TR1, SCR1, and, at the same time, capacitor C3 is charged through resistor R2. The coil 3 then changes-over the switch 4, any charge on capactor C2 shortening the delay before rectifier SCR4 is switched-on. If the motor current is interrupted when the motor is in the fully-on condition, maximum time delay is imposed before a conducting path is provided for the circualting current. Restoration of the current in the reverse direction through either the armature or the field provides a braking torque. Coil 3 changes over the switch 4, and rectifier SCR4 is turned-on after a delay whereby the motor self-excites until coil 3 responds to a falling current level. Switch 4 returns and braking energy is applied progressively as the firing-delay of rectifier SCR4 decreases. Capacitor C3 is re-charged while the motor is at standstill, to enable restarting to take place at a slow rate. If the motor is being pulsed when reverse-current braking is applied, the capacitor C3 is restored to a fully charged condition to impose maximum delay in firing the rectifier SCR4.
