Title: Improvements relating to circuits for counting electrical pulses emitted in the sensing of fluid flow
Inventor: CHAPPELL EDGAR RAYMOND REGINAL
IPC: H03K25/00
Filed: 1957-08-21
Abstract: 832,411. Total flow meters. SIMMONDS AEROCESSORIES Ltd. Aug. 13, 1958 [Aug. 21, 1957], No. 26397/57. Addition to 803,070. Class 40 (1). A " cup and bucket " pulse counting circuit as claimed in the parent Specification, is adapted for metering fluid flow by counting the pulses emitted by a flow sensing unit at a frequency dependent on flow rate. It includes a potentiometer manually adjustable in accordance with the density of the liquid and a thermistor network so that, with the potentiometer set for a given liquid, the count is given in terms of mass flow independently of temperature variations of the fluid. The Figure shows a fluid-flow meter in which pulses from a flow meter sensing unit S of the type described in Specification 803,069 causes pulses to be emitted from a pulse generator 1 in dependence upon the fluid flow. These are fed to a " cup and bucket pulse counter comprising an integrating capacitor 5, the charge upon which increases incrementally with each pulse from generator 1 until at a given charge level tube 7 conducts to trigger device 18 and operate relay 17, the armature of which is connected with a mechanical counter C. The point at which diode 25 conducts is determined by the setting of potentiometer 30 which is coupled to a calibrated dial 32 and set according to the specific gravity of the fluid whose flow is to be measured. The point of conductivity of diode 25 depends also upon the thermistor network 34, 35, the resistance of which depends upon the temperature of the fluid. In this way the count is dependent on the mass of liquid flowing and automatically compensates for changes in density due to temperature variation. The circuit may be combined with a rate of flow meter as described in Specification 832,412. The potentiometer and thermistors may be used to vary the reference voltage applied to terminal 6 by connecting them in series in a bleeder resistance chain connected across the H.T. supply or they may be used to control the amplitude of pulses from the pulse generator 1.

Title: Timing pulse generator
Inventor: DELFOSSE JEAN
IPC: H03K3/315
Filed: 1968-06-06
Abstract: 1,220,505. Transistor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORP. 6 June, 1968 [14 June, 1967], No. 26879/68. Heading H3T. In a pulse generator having input pulses applied to a gate 4 via a delay device 3 and to the set input of a latch or bi-stable circuit 2, the output from the latch circuit is connected to the gate 4, so as to enable the gate to pass signals from the delay device 3, and is also connected to a control circuit including a single-shot multivibrator 6 and/or 7 which is effective when activated to reset the latch and to hold the latch reset for a time at least equal to the period of the multivibrator. As shown input signals (A, Fig. 3, not shown) at E trigger tunnel diode TD1 to produce negative pulses (B) which are inverted and differentiated in circuit 10 which includes a coaxial inverter I.C. to produce positive pulses (C) at the input to the latch or bi-stable circuit 2. This causes the bi-stable circuit 2 to attain the set state in which tunnel diodes TD2 and TD4 are in their high voltage state, diodes D1 and D3 are OFF and transistor Tl is ON. The tunnel diode TD3 of the gate 4 is biased near its peak current and when the delayed signal (G) from delay line 3 occurs it is triggered to produce a negative pulse (R) at the output S which controls a scanning device (5, Fig. 1, not shown), of an oscilloscope. The output (E) of the transistor T1 is passed via a coil H, which introduces a time lag, to the input of a single shot circuit 6 which turns OFF transistor T3. The output (k) of T3 is fed via a delay line 8 and via a further single shot circuit 7 to an OR gate 9. The delayed output (M) from line 8 activates gate 9 causing T6 to conduct and produce a negative output (N) which resets the bistable circuit 2. The tunnel diodes TD2, TD3 and TD4 assume their low voltage state, transistor T1 turns OFF and a positive output pulse (R) is produced. At the end of the unstable period of the single shot circuit 6 the transistor T5 is turned OFF so that the single shot circuit 7 obtains its unstable state. The output (L) of this circuit causes T7 to conduct so that the bi-stable circuit 2 is held in the reset state until the end of the unstable period of circuit 7 when it can be triggered into the set state by the next input pulse.

Title: Improvements in and relating to variable equalisation
IPC: H04B3/06
Filed: 1968-06-06
Abstract: 1,220,877. Line equalizers. MILGO ELECTRONIC CORP. 6 June, 1968 [1 March, 1968], No. 26882/68. Heading H4R. In a system for adjusting equalizers to compensate for distortion in a telephone line test signals comprising bursts of carrier, equal in length to a digit period, with adjacent digit periods or pairs of periods blank are transmitted over the line and at the receiver the incoming signal after passing through an adjustable equalizer is suppressed during the carrier burst but allowed to pass during the adjacent blank periods, to be integrated and indicated on a meter which therefore indicates the value of the error signal. The adjustable equalizer is then adjusted by a series of successive approximations to reduce the meter indication to a minimum. Fig. 1 shows the transmitter in which data is normally applied from terminal 9 via a gate 5 and a series to parallel converter 10, 15 and 20 to data converter of the type of Specification 1,220,879 to provide a phase shift modulated carrier which, after filtering in 55 and converting to the appropriate telephone frequency band is applied to the line at 70. For adjusting the equalizers at the receiver a test control unit is actuated which interrupts the incoming data at gate 5 and enables a test pattern generator to feed a test pattern to the data converter. In addition a squelch circuit 53 is operated to provide a transmitted signal comprising bursts of carrier of digit length with one digit or two digit intervals between. At the receiver, Fig. 2, the received signal is filtered, passed through the equalizer system 75, shifted to a higher frequency to define the envelope with greater precision, and envelope detected in detector 71. A level detector is connected to the envelope detector output and controls a gating device 73 which samples the envelope detector output at the centre of the data pulse periods in which the detector output level is below a threshold value corresponding to the reception of a burst of carrier, i.e. samples are taken of the signal level in the intervals when the carrier signal is blanked off. The samples are integrated in integrator 80, the signal level in which is indicated on the meter 85. The equalizer comprises fixed amplitude and delay sections switched in or out to provide rough equalization together with a number of continuously variable amplitude and delay control devices, providing control at various points across the signal band, which are adjusted successively to reduce the reading on the null detector 85, Fig. 2.

A vehicle change-speed gear is controlled by a set of electric press-buttons M, VR (normal forward drive), E (low speed), N (neutral), R (reverse) and P (parking), each, with the exception of N, having a contact-establishing rod 12 engageable in a vertical column of balls 14, 15 loaded by springs 17, 17<SP>1</SP> and being held when depressed by the engagement of a cam notch 9 with one of a series of lugs projecting from a vertical locking-bar 1 loaded by a spring. The N button is designed to permit operation of only certain of the remaining buttons at any one time, and for this purpose is provided with a plunger 10 formed with longitudinally-spaced upper and lower recesses 11, 11<SP>1</SP>. With button N in its normal position, Fig. 5, the upper surface of plunger 10 locks the balls 14 against spring 17<SP>1</SP>, thus preventing operation of any of the buttons E, R, P, but recess 11<SP>1</SP> permits operation of either of buttons M, VR. When button N is depressed, however, the balls 15 are locked by the lower surface of plunger 10, and recess 11 permits operation of any one, but not more, of buttons E, R, P. The lift of the cam notches for buttons M, VR is greater than that of the notches for buttons E, R, P (Fig. 5) so that any one of the latter buttons, if depressed, may be released from locking-bar 1 by the operation of either of buttons M, VR, independently of button N, but operation of any of buttons E, R, P will not displace the bar 1 sufficiently to release any of buttons M, VR, N, if depressed.
