Title: Gluid flow measuring device particularly petrol flow measuring device for motor vehicles
IPC: G01L9/00
Filed: 1975-09-03
Abstract: 1519803 Measuring fluid-pressure electrically LICENTIA PATENT VERWALTUNGS GmbH 3 Sept 1975 [3 Sept 1974] 36305/75 Heading G1N(A) A pressure difference set up between chambers 4 and 8 by fluid e.g. petrol, flowing through a Venturi 6 causes deflection of a metal disc 23 towards an inductance 10 and changes the resonant frequency of an L.C. oscillator, Fig. 2, delivering a D.C. voltage Vosc to an indicator, the voltage Vosc. being inversely proportional to the high frequency current. The chambers 4 and 8 are separated by an elastic non-conducting diaphragm 26 and the low-pressure chamber 8 is provided with concentric steps 64 to provide graded support for the deflecting disc and diaphragm. The inductance 10 may alternatively be located adjacent the high-pressure chamber. To provide a measure of, for example, litres per hundred kilometres travelled by a motor vehicle the output Vosc is applied via a linearizer (46), Figs. 20 and 27 (not shown) to an integrator (47), the capacitor (49) of which is periodically discharged by a switch (50) comprising drum contacts (53), Fig. 21 (not shown) rotating with the tacho drive-shaft. An instrument (35) displays the mean value of the time-integral curve. In an alternative embodiment the rotary switch (55), Fig. 23 (not shown) has changeover contacts connected such that the integrator output is applied to the instrument (35) only during a short period (t2) Fig. 26 (not shown) of each charging cycle. The linearizer (46) comprises two transistor amplifier stages (T r , Fig. 27) each with variable negative feedback. Charging of capacitance (49) is accomplished via a constant current source (67). Alternative linearizing circuits utilize the characteristic curve of a transistor (38), Fig. 15 (not shown) or that of serially connected diodes (41), Fig. 17 (not shown). A Zener diode (45), Fig. 18 (not shown) may be connected at the output of the linearizer to compress the upper end of the instrument scale.

Title: Keyboard terminals
IPC: G06K1/06
Filed: 1970-07-30
Abstract: 1317756 Keyboard terminals INTERNATIONAL BUSINESS MACHINES CORP 30 July 1970 [29 Sept 1969] 36885/70 Heading G4H A keyboard terminal comprises keys 10 each of which when actuated causes a respective trigger circuit 42 to generate a trigger signal, latch circuits 44 each associated with a respective one of the trigger circuits and effective to provide an output signal when triggered by the associated trigger circuit and encoders 45 which are capable of encoding a succession of the output signals despite an overlap in the timing of the corresponding trigger signals. The circuit shown in Fig. 5 is incorporated in each module 15 associated with a respective key 10 and each encoder comprises an array of pins connected to an etched wire pattern, Fig. 6 (not shown), which forms a bus 11. The depression of a key moves a magnet (58), Fig. 11 (not shown), towards a piece of indium antimonide (59) thereby changing its resistivity and supplying a voltage change to the pin connections thereby providing a unique 8-bit coded signal for each key. The coded signals address a data store 12 which supplies a B.C.D., ASCII or EBCDIC coded signal representative of the actuated key. Control timing and interlock circuits 14 transfer the coded signal to a register 17 for temporary storage and for connection to a printer (not shown) via a bus 18. If a high speed display is used instead of a printer, the bus 16 is connected directly to the display. The provision of the latch circuits 44, the output pulses from which do not overlap in spite of overlap of the output signals from trigger circuits 42, ensures that characters are not lost. Instead of using a magneto resistive effect in the encoders, a capacitative bridge, inductive coil, Hall effect or light emitting circuits may be used.

Abstract: 433,360. Electric signalling systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 28, 1934, No. 37198. Convention date, June 7. [Class 40 (i)] The re-active torque in an induction alternating-current transmitter is eliminated by displacing the phase of the induced current through 90 electrical degrees. As shown in the Figure the stator of the transmitter is fed withalternating current through a voltage regulator K. The rotor is moved by the meter M, the reading of which is to be transmitted, so that a current proportional to the position of the meter is transmitted through mechanical rectifier G to indicating, recording and metering instruments A, S, Z. A condenser C shunted by a resistance R is provided in the circuit of the rotating coil W2, the capacity of which is proportioned so that the phase displacement between the field in the air gap and the induced current flowing through the rotating coil amounts to 90‹. Under these conditions the coil W2 cannot develop active torque and consequently exerts no reactive torque on the transmitter instrument M. The capacity of the condenser can be calculated or can be obtained experimentally by adjusting the circuit until no reactive effect on the meter is produced. A system using an induction - type receiving instrument is also described and details of suitable values of the various components are given in the Specification.

Abstract: 816,938. Counting-apparatus. ENGLISH NUMBERING MACHINES Ltd. Jan. 22, 1958 [Dec. 9, 1957], No. 38257/57. Class 106 (1). In counting apparatus, the means for rotating the units numeral wheel comprise three ratchet wheels mounted coaxially with one another and with the units wheel, to which the intermediate ratchet wheel is keyed. As described, a driving spindle 16 oscillates through 36 degrees between two positions defined by stops 26, 27, engageable by a pin 30 fixed to the spindle. A driving ratchet wheel 14 bearing ratchet teeth 13 on one of its faces moves with the spindle 16, the teeth 13 engaging with teeth 12 on one side of an intermediate ratchet wheel 6, rotatable on the hub 15 of the wheel 14, so that rotation of the spindle 16 in one direction effects an operative drive of the intermediate wheel 6, thereby rotating the units numeral wheel 1 by means of projections 7 engaging with axial slots 2. in the numeral wheel. Rotation of the spindle 16 in the other direction is inoperative due to the engagement of ratchet teeth 11 on the other side of the intermediate wheel 6 with the teeth 5 of a third, stationary, ratchet wheel 4. The three ratchet wheels 4, 6, 14 are urged together by a spring 22 arranged in the gap between the ratchet wheel 14 and a cover-plate 21. The spindle 16 is restrained from axial movement by clips 24 which engage in grooves 25, and its return rotational movement may be effected by external mechanical means or by a spring 31. Overtravel of the numeral wheel 1 is prevented by ensuring that the gap 23 between the wheel 14 and the cover-plate 21 is sufficiently narrow to prevent the intermediate ratchet wheel 6 sliding over the crests of the other two ratchet wheels simultaneously. By omitting the stops 26, 27, the pin 30, and the spring 31, the counter may be used for continuous rotary movement, with each digit position indexed by the ratchet mechanism.
