Title: Improved Means for Pick-Up Arm Location in an Automatic Record Player.
Inventor: LANE NORMAN
IPC: G11B3/08
Filed: 1967-12-22
Abstract: 1,197,739. Record changer. BSR Ltd. 9 Jan., 1969 [22 Dec., 1967], No. 58323/67. Heading G5B. In an automatic record change mechanism for different size records in which a member 27 controlling pick-up arm movement is oscillated once about its pivot 28 during each change by the usual cam wheel rotation, the pick-up arm is moved horizontally by engagement of a drive pin 43 on a quadrant selector arm 33, which is secured to the pick-up arm, by a lug 44 mounted on the member 27 and tiltable against the action of a spring out of engagement with the drive pin. The oscillating member 27 is driven initially anticlockwise from the cam wheel by roller 26 and is formed with a ramp 32 which co-operates with a pin 30 to lift the pick-up from the record. Leading edge 44b of the tiltable lug 44 now engages pin 43 to swing the quadrant plate and the pick-up arm until the latter reaches its fully outward position at which the quadrant plate engages a stop (not shown). The lug now tilts and passes under the pin 43. As the oscillating member approaches its other extreme position abutment member 57 engages a finger 53 to disengage it from an abutment 58 on a selector bar 36. This enables the bar 36 to pivot under the action of spring 38 to bring its abutment 42a into engagement with a recess 42 on a member 39 which is set in accordance with the size of the record to be played. On the return of the oscillating member the other side of the part 44b of the tiltable member now engages pin 43 on the quardant member thus the member and the pick-up arm are caused to swing inwardly until one of the abutments 35 engages abutment 39a on bar 36 which has been positioned in accord with the record size. The lug then rides over the drive pin 43 and continued movement of the oscillalating member lowers the pick-up on to the table by co-operation of pin 30 with ramp 32 and at the same time abutment 56 moves finger 53 into engagement with abutment 58 on the selector bar 36 and swings the latter out of engagement 58 on the selector bar 36 and swings the latter out of engagement with the quadrant selector plate 33 thus freeing the pick-up arm to play the record.

Title: Automatic brighness control for image intensifier tube
IPC: H02M3/28
Filed: 1973-12-18
Abstract: 1450699 Cathode-ray tube circuits RCA CORPORATION 18 Dec 1973 [30 March 1973] 58559/73 Heading H4T A non-linear impedance comprising, as shown in Fig. 1, diodes 22a-22d (but which may comprise a resistor shunted by a Zener diode) connected in the current path of the photocathode, 12a of the first stage of an image intensifier 12 is connected to input D of a current regulator 18 to control the current supplied by battery 20 to an oscillator 16 the output of which, after rectification and multiplication in voltage multiplier 14, supplies increasing D.C. voltage steps V 1 , V 2 , V 3  to the photo-cathodes 12b-12d of the image intensifier. In the operation of the arrangement, at low light input levels e.g. less than 10<SP>-1</SP> foot candles (see Fig. 2) negligible current flows in the current path of the first stage of the intensifier so that a negligible voltage is developed at point D with respect to ground. Transistor 40 in regulator 18 is therefore cut-off and the current supplied to the oscillator 16 from battery 20 is substantially constant and determined by the setting of resistor 38 which with a negative temperature coefficient thermistor 36a and a positive temperature cofficient sensing element 36b forms a biasing network for transistor 34. When the input light level exceeds 10<SP>-1</SP> foot candles the voltage at the point D increases as a log function of the increase in input light level and when this voltage is sufficient to forward bias the base-emitter junction of transistor 40 the latter starts to conduct and as the light input increases transistor 40 becomes heavily conductive so that transistor 34 saturates. The regulator 18 then exercises no control and the current demand of the intensifier at higher input light levels is satisfied.

Title: Magnetic switching device
IPC: H03K17/97
Filed: 1973-12-19
Abstract: 1413196 Magnetic switching device ILLINOIS TOOL WORKS Inc 19 Dec 1973 [8 Feb 1973] 58927/73 Heading G1N [Also in Division H3]  False switching of a bi-stable circuit 32 under the control of a switching device of the type including a closed magnetic core 36 threaded by drive 38 and sense 43 windings and controlled by movable magnet 37 is avoided. Capacitor 42 is alternately charged and then discharged through drive winding 38 under the control of transistor amplifier 39 which is rendered periodically conducting by clock pulses from generator 31. If permanent magnet 37 is positioned away from core 36 the latter is unsaturated and output pulses induced in sense winding 43 are coupled to the switching input 33 of the bi-stable circuit 32. So that the circuit 32 is not triggered by noise signals on sense winding 43 clock pulses from 31, delayed by circuit 46 so that their positive edges coincide with the peak of the sense winding pulses are applied to clock input terminal 34. Circuit 32 only changes its state if both a positive edge of a clock pulse is present at 34 and a switching input signal above a predetermined level is present at 33. Circuit 32 returns to its initial state at the negative edge of the clock input and no input above a second lower predetermined level is present at 33. The second level being set by feedback resistor 43 which gives the current an hysteresis characteristic. In an alternative arrangement, Fig. 1 (not shown), a sine wave oscillator feeds the drive winding via an amplifier and the delayed clock input is obtained by feeding the oscillator output to terminal 34 via a Schmitt trigger alone or in series with a delay circuit.
