Title: Peak and slope detector
IPC: G11B20/10
Filed: 1964-09-25
Abstract: 1,085,896. Peak detector. GENERAL ELECTRIC CO. Sept. 25, 1964 [Sept. 30, 1963], No. 39289/64. Heading H3T. A transistor circuit for detecting the peak of an input waveform, e.g. from a magnetic tape or drum comprises a transistor stage 10 having a signal input electrode connected via a capacitor 25 to an input terminal 26 and an output electrode connected to an output terminal 30 and a semi-conductor diode 19 connected between the input and output electrodes to form a feedback path the arrangement being such that as an input signal which is generally a smooth curve with a peak intermediate the beginning and end of the signal, increases in magnitude towards the peak, the feedback path passes a feedback current to charge the storage capacitor 25 at a rate sufficient to follow the rate of change of the input signal and maintain the input transistor stage substantially in the same conductive condition, and thereafter when the input signal attains its peak the storage capacitor discharges rapidly through the input electrode initiating transfer of the transistor input stage to a second conductive condition effectively cutting off the feedback path to provide a substantially square wave pulse at the output terminal. Fig. 1 shows a circuit in which initially transistor 10 is biased to conduct slightly. When an input pulse (Fig. 3, not shown) applied at 26 reaches position (B) and increases negatively, a feedback current I 4  flows from the supply terminal 16 through the Zener diode 19 to charge the capacitor 25 to the polarity shown, so maintaining the output voltage (Fig. 4, not shown), between period (AC) approximately constant. As the input pulse reaches a maximum and decreases in period (CD), the capacitor 25 causes a discharge current I 6  to flow to the base 12 which causes the transistor to conduct heavily and so the output point 30 becomes near earth potential as shown in period (CD). The low potential now between points 20, 21 cuts off the Zener diode 19 and prevents feedback current I 4  from flowing. The Zener diode can be replaced by an oppositely poled ordinary diode, biased at a point remote from the vertex of the parabolic curve of the diode where for a small change in voltage a large change in current occurs. An amplification stage using one or more transistors can be connected in the feedback path between the diode 19 and the point 21.

Abstract: 1304136 Resettable counters VEEDER INDUSTRIES Inc 26 Aug 1971 [8 Sept 1970] 40099/71 Heading G4D A counter which can be reset to a variable preset count includes a resetting member which moves in a first direction to cause the counter wheels to be reset. During this motion presetting mechanism for stepping each of the wheels to a desired count is held inoperative. The resetting member now moves in a second direction, allowing the wheels to be stepped to the desired count but preventing resetting cams from being rotated.  The resetting member 64, Figs. 2 and 3, is initially moved horizontally by pushing button 20 to the right. This causes resetting fingers 62 to be brought down on the heart-shaped resetting cams. The cams are on wheels which move with the counter wheels during counting and resetting but which can move independently of the counter wheels during presetting. At the same time the transfer wheels 50 are pulled away from the counter wheels. During horizontal movement of member 64 a lug 122 on button 20 holds arm 116 in the position shown in Fig. 2, the arm preventing each pawl 102 from engaging the teeth 38 of the associated counter wheel, towards which it is urged by eccentrically-mounted spring 108. When member 64 has been pushed sufficiently far to the right it pivots about shaft 74 as eccentric plug 82 enters the vertical slot 84. The plug prevents spring 68 from returning member 64 to its normal position. Because button 20 has moved upwards arm 116 release the pawls 102 so that when any of the presetting buttons 26 is pressed the corresponding counter wheel will be stepped. The cam wheels are prevented from moving by the resetting fingers 62. When button 20 is pressed down, plug 82 is disengaged from the vertical slot, pawls 102 are disengaged, and spring 68 urges member 64 to the left with consequential release of the resetting fingers.

Abstract: 1441660 Automatic control of exhaust gases ROBERT BOSCH GmbH 24 Aug 1973 [29 Aug 1972 1 Aug 1973] 40159/73 Heading G3R [Also in Division F1] In an I.C. engine fuel metering system the fuel/ air ratio is determined by the pressure in a fuel reservoir 7, Fig. 1 connected to an intake pipe 1, and the fuel reservoir air space communicates through conduit 11, 12 with portions of the intake pipe upstream and downstream of throttle 3, the flow throughput of the conduit being variable in dependence on the output signal of a probe measuring the exhaust gas composition to vary the pressure in the fuel reservoir air space. Flow from conduits 11, 12 to conduit 9 (through orifice 18 from conduit 11) is controlled by a solenoidoperated valve-member 14, the solenoid being energized by the current from the exhaust gas measuring probe. The valve member 16 may open or close the ends of conduits 11, 12 in proportion to the excitation of the solenoid 13 or the valvemember may be moved to close the seats 16 or 17 alternately at regular intervals. In another embodiment conduits 11, 12 Fig. 2 (not shown) are opened or closed simultaneously or alternately by solenoid valves 20, 21. An exhaust gas measuring probe 23 of solid electrolyte e.g. sintered zirconium dioxide coated on each side with micro-porous platinum, is contacted by exhaust gas and air on opposite sides, the oxygen ions in the exhaust gas being conducted by the solid electrolyte so that a potential difference occurs between the two sides which is dependent on the exhaust gas composition. The probe output is passed via a pulse shaper 28 to produce a rectangular characteristic which is divided by an integrating controller 29 into uniformerly rising and falling curve portions from which high and low voltages are separated by threshold value amplifiers 26, 27 so that solenoid valve 20 is controlled by voltages below a lower threshold and solenoid valve 21 is controlled by voltages above a higher threshold. In a modification a by-pass 35, Fig. 7 (not shown) controlled by a solenoid valve 36 mitigates the effect of slow variations in exhaust gas composition during engine idling. Valve 36 may be controlled by the circuit of the probe 23 by engine speed, ignition frequency or in dependence on load.
