Title: Improvements in and relating to capacitor charging circuits
Inventor: BANNER AUBREY EDWARD

Abstract: 1,215,293. Integrators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 27 Nov., 1967 [1 Dec., 1966; 29 Dec., 1966], Nos. 53877/66 and 53220/67. Divided out of 1,167,341. Heading G4. A drift and leakage corrected integrator for use in a mass spectrometer of the kind described in Specification 1,167,341 (Fig. 3, not shown) receives the output of a pick-up coil PC responsive to changes of flux B in the magnetic analyser of the spectrometer to develop current I Fα  dB/dt fed over switch S3 to operational amplifier A1 having a feedback integrating capacitor C, whose output representing change of flux from an initial value is combined with a calibrating voltage from VR1 representing such value, at the input of operational amplifier A2 whose output V B  represents the flux B. Constant input offset currents and voltages are cancelled by adjustment of VR2 and leakage drift current I 2  in the capacitor is cancelled by current I 2 <SP>1</SP> from VR3 in the output of unity gain inversion amplifier A3, energized from the output of amplifier A1. Initially the input of the latter is earthed over S3 and VR2 is adjusted for zero drift; a positive voltage is applied over S3 and VR3 is adjusted for zero leakage drift. The circuit is enclosed in a constant temperature enclosure and temperature variable resistors of e.g. silicon are connected in series with resistors R4 or R5 of amplifier A3 for further compensation. The output of A2, V B αB, and a voltage V A  representing the accelerating voltage of the spectrometer are applied as V X  = V B , V Z  = V B  and V Y  = V A  to a multiplier/divider circuit MDC to produce an output proportional to V X V Z /V Y  = V B <SP>2</SP>/V A . An auxiliary pick-up coil APC (which may be in two symmetrical sections) positioned at the edge of the polepiece of the analyser and between the electromagnet coil and the ion tube (Fig. 3, not shown) is connected in series opposition to pick-up coil PC to compensate for magnetic errors due to eddy currents. In the integrator, resistor VR5 is connected between A1 and A2 in parallel with legs containing diodes D 1 , D 2  in series with VR6, VR4 respectively. At calibration, capacitor C is shorted by S3<SP>1</SP> for a reference peak due to a substance of mass 500, and the pick-up coil is arranged so that the output of A1 swings positive for reduction in scanning field, i.e. decreasing mass number, and vice versa. Thus by adjustment of VR5, VR6, VR4, diodes D 1 , D 2  conduct successively to increase the gain of the system for masses greater than 500, thereby correcting non-linearity errors.

As shown in Fig. 1, a preliminary mould is reciprocable between extrusion station I and first blowing station II and a blowing assembly 9 is rotatable to transfer mandrels 14, 16 between station II and final blowing station III, where there is a stationary final blow-mould 2. A tubular extrudate 3 is continuously extruded from nozzle 5 into mould 1 and severed by knife 12 while a finished moulding 8 cools in mould 2. Mould 1 moves in the direction of arrow a to station II and extrudate 3 is blown therein by mandrel 14 to preform (7) while article 8 drops from opened mould 2 on retraction of mandrel (16). Mould 1 then opens and returns to station I to receive further extrudate while assembly 9 rotates to place preform (7) on mandrel 14 at station III where it is finally blow-moulded in final mould 2. Alternatively (Figs. 4-6, not shown), both blow-moulds are movable and a single, stationary blowing mandrel is used. In a further alternative, the preliminary blow-mould is stationary, extrudate being fed thereto by grippers or by rotating the extruder. A plurality of final moulds may be used per preliminary mould and more than one preliminary mould may be used. A further chilling "mould" and chilling and/or ejection stations may be incorporated.

Abstract: 1285592 Cathode-ray tube circuits; transistor switching circuits MARCONI CO Ltd 25 Aug 1970 [7 Nov 1969] 54560/69 Headings H3T and H4T The voltage between the target and cathode of a photo-conductive type television camera tube (e.g. a Vidicon) is increased during brief intervals which precede and succeed the line and field retrace periods. This arrangement prevents the appearance of bright edges in a television picture reproduced from video signals generated by the tube. The Specification states that such defect is believed to be due to surface electrical leakage across the face of the photoconductive target and a theory is advanced which takes into account surface leakages between four distinct areas on the target, viz., the area from which useful video signals are derived, the area occupied by the scanning raster, the area occupied by the optical image and the area of the target itself, such areas being of successively greater dimensions. Fig. 1 shows a schematic representation of an embodiment in which the target is depicted as comprising a metal signal plate SP the photoconductive layer on which, notionally, comprises a plurality of elements each consisting of a capacitor K1 ... Kn in parallel with a current source J1 ... Jn surface leakage being represented by resistances R1-2, R2-3 &c. and the target being scanned by a cathode-ray beam CR from cathode C which during brief intervals preceding and succeeding the line and field retrace periods is connected to earth by means of switch S to produce the required increase in target-cathode voltage. Fig. 2 shows a preferred embodiment of the switch and comprises PNP transistor T1, NPN transistor T2 and PNP transistor T3 connected in series across the H.T. source of Fig. 1, the junction between T1 and T2 being connected to the cathode C and the base T3 connected to the collector of a further NPN transistor T4. A waveform derived from the line and field deflection circuits and having positive portions during trace intervals and negative portions during fly-back intervals switches T1 and T2 alternately so that the cathode is connected to the tapping on potentiometer P during trace intervals and to the 30 v. supply during fly-back intervals. A waveform also derived from the line and field deflection circuits, switches T4 "on" for intervals slightly longer than the fly-back intervals and thus connects the cathode to earth to increase the target-cathode voltage, during brief intervals preceding and succeeding the fly-back intervals.

Abstract: 1378400 Alarm timepieces DAINI SEIKOSHA K K 30 Nov 1972 [9 Dec 1971 17 Dec 1971] 55297/72 Heading G3T An alarm watch incorporates a Piezo-electric buzzer alarm and a driving circuit therefor which is energized at predetermined times via a switch SW (Fig. 4) operated by the watch timing mechanism. The Piezo-electric element 3 is mounted on an inner back cover-plate 2 and an outer back coverplate 1 is provided with an annular row of holes. DRIVE CIRCUIT OPERATIONWhen a capacitor C 1 charges to a value in excess of the threshold of a diode D, a transistor T r  is caused to conduct current through a coil half La inducing a voltage in Lb which is fed back via C 2  to the base of T r . The circuit begins to oscillate at a resonant frequency determined by L and C 2  and oscillation continues until C 1  is completely discharged so that Tr will turn OFF and the oscillation stops. The cycle is then repeated until switch SW is opened by the timing mechanism. The oscillation frequency preferably conforms to the resonant frequency of the Piezo-electric element 3, the element 3 being driven by the voltage across the coil.

Filed: 1974-12-24
Abstract: 1495759 Digital detecting apparatus GULF & WESTERN INDUSTRIES Inc 24 Dec 1974 55782/74 Heading G1N [Also in Division G4] Digital detecting apparatus for creating an output signal when an electrically conductive object comes within the field of effect of a loop comprises means for creating a pulse train having a frequency controlled primarily by the inductance of the loop; means for counting the pulses of said pulse train during a selected time interval to produce a count generally representative of the frequency of said pulse train during said time interval; means for creating a representative count; means for comparing the representative count with the reference count; and means for creating an output signal when the representative count differs from the reference count by at least a pre-selected amount in a selected numerical direction. The apparatus may be used in detecting vehicles for traffic control purposes, or in a metal detector for security checks. As shown, a digital loop detector system A includes a loop B generally positioned in or adjacent to a road, capacitor C and oscillator D. The latter produces a pulse train the frequency of which is determined by the inductance of loop B and the capacitance of C. The output of oscillator D is amplified by squaring amplifier E to produce a pulse train tL which is fed into a processing circuit F. The pulse train tL is gated to counter 12 via a gate 18 which is controlled by a crystal controlled interval generator 20 through line 22. The counting interval may be selected to be 50, 100; or 200 ms. The sequence control and decision logic circuits 30 are controlled by counter 10, reference counter 12 and comparator 14. Line 32 represents the function of incrementing counter 10 by a unit change. Line 34 represents the function of gating a completely new count into counter 10. Output line 36 controls the output of the detector, which may be a relay, transistor switching circuit, or optical coupled output. The circuit 30 may be controlled externally by a forced drift oscillator 50, the function of which is to enable the detector A to forget a vehicle remaining in the field of loop B for a prolonged time interval. The output of oscillator 50 may be adjusted via line 52. The interval generated by generator 20 may be selected by logic on lines 54. A line 56, controlled by a manually adjusted switch, may be provided to change the system "A" from a pulse mode to a presence mode of operation. In the pulse mode, a uniform pulse is created in output line 36 for each detection, whereas in the presence mode, the output line is activated for the time that a vehicle is being detected and before it is forgotten by the forced drift feature using oscillator 50. Reference has been directed by the Comptroller to Specification 1398937.
