Abstract: 283,386. Shimizu, S. April 23, 1927. Dynamometers, rotary - transmission. - Comprises a particular construction of the type in which the torsion of a shaft is measured by the variation in an electrical resistance. Inner and outer casings Q, P are secured to a shaft S at sections S1, S2 at some distance from one another. V-shaped conductors E arranged in a series of axial rods are secured to the outer surface of the casing Q and connected as shown to slip rings C1, C2 insulated from the shaft. To the inner surface of the casing P, insulated therefrom, and immediately over the conductors E are secured conductive bridge pieces D each of which engages one row of the conductors E with a suitable pressure. An electric circuit is connected to the brushes B1, B2 and the change in the resistance of the conductors when the shaft is under and not under torsion is measured by a bridge method. A correction for temperature will have to be made unless the conductors are made of material rendering this unnecessary. In a modification two rows of resistances are used reversely and the ends connected to four slip rings so that each row is in one arm of the bridge.

Filed: 1972-03-09
Abstract: 1390041 Measuring pressure electrically REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 9 March 1972 [19 March 1971] 11068/72 Heading G1N The mean pressure of a fluid undergoing  cyclical pressure variations, for example the  pressure in the induction manifold of an I.C. engine, is determined by integration over a period whose start and finish are determined by a pick-up device responding to a member mechanically associated with the means causing the cyclical pressure variations. As shown, a rapidly responsive pick-up P, which may be of the quartz or strain gauge type, senses the induction manifold pressure in an I.C. engine and provides a signal e 2  which is fed through a resistor r 3  and F.E.T. switch 7 to one input of an operational amplifier 8 to which input is also connected to a capacitor C i . The output of the amplifier 8 is fed through a F.E.T. switch 9 to a capacitor C m  whose output P m , which is a measure of the desired mean pressure, is fed to a computer C. A boss on the flywheel of the engine is sensed each half revolution (which is the period of cyclical variation of pressure for a four cylinder engine) by electrostatic or electromagnetic pick-ups C 1 , C 2  providing a pulse train Q Fig. 2 (not shown). This signal is applied to monostable multi-vibrator 13 controlling F.E.T. 9 for a time sufficient to permit the output of the integration capacitor C 1  to be transferred to C m . Pulse train Q also operates through a monostable multi-vibrator 14 to discharge also reset the capacitor C i  by controlling an F.E.T. 10. Integration is then performed for a time controlled by the operation of F.E.T. 7 under the control of a signal S 3  derived through an ORNO gate 12. This gate prevents integration during the above-mentioned resetting period. The computer C may be of analogue or digital type. The measuring system is applicable to fuel injection systems and determination of ignition point and injection times in engine control.

Abstract: 332,650. Smith, N. W. Jan. 11, 1930. Latches, sliding.-A latch bolt c of a fastening particularly for the doors of motor vehicles is held retracted by a spring f and is shot, upon closing the door, by pressure of a spring m housed in a plunger k which is engaged and forced inwards by the striking plate, not shown. Plunger k carries an antifriction ball n. A lever h, pivoted at i, extends through a slot in the plunger k and has disc and socket articulation at g with bolt c, so that when bolt c is retracted, plunger k is shot. When the door is closed, the striking plate moves the plunger inwards, putting the spring m in compression until bolt c registers with its aperture in the striking plate, when it is shot by the action of spring m. The distance of pivot i from bolt c is two or more times its distance from plunger k so that movement of bolt c is correspondingly greater than that of the plunger. Spring f is tethered at one end to a fixed pin r and at the other to the arm q of a follower operable by the spindle o of an outside handle. The tension of spring f is thus applied to hold bolt c retracted through the follower q and lever h. Lever h extends upwards and forms an inside handle j. Pivoted on pin r is a cam s operable to bear against lever h and prevent withdrawal of bolt c. A slidable detent x may be provided to engage bolt c to hold it in either its shot or retracted position. The position of pivot i is adjustable in a slot in plate a to vary the throw of the bolt &c. and corresponding adjustment of plunger k may be effected by a screw w.
