IPC: G01P3/48
Filed: 1959-07-16
Abstract: 855,611. Frequency discriminators. DISA ELEKTRONIK AFDELlNG AF DANSK INDUSTRI SYNDIKAT COMPAGNIE MADSEN S. A. July 16,1959, No. 24517/59. Class 40(5). A frequency measuring circuit comprises a limiter for the input voltage including an impedance 3 and a Zener diode 5, the output voltage pulses of which are applied to a counting circuit consisting of a condenser 8, transistor 6 and meter 7, base of the transistor being supplied with a voltage dependent on the input voltage and the discharge of the condenser being controlled by the emitter-collector path of the transistor. The arrangement is such that when the voltage at terminal 1 is positive with respect to that at terminal 2 the condenser 8 is charged, transistor 6 being then cut off. When voltage in terminal 1 becomes less than that in terminal 2, transistor 6 is rendered conducting allowing condenser 8 to discharge. The reading on meter 7 will thus be proportional to the frequency of the input voltage. In Fig. 2, the input is derived from a tacho-generator, the rate of revolution of which it is desired to measure. In another embodiment (Fig. 3, not shown) the transistor base voltage is derived from an auxiliary coil on the tacho, or it may be derived from a transformer connected across the input (Fig. 4, not shown). The meter may alternatively be included in the discharging circuit of the condenser.

Title: Device for converting a rotating motion into a rectilinear reciprocating motion and for producing combined reciprocating and rotary motion
IPC: F16H25/12
Filed: 1935-09-09
Abstract: 462,666. Reciprocating-saw machines. DIRIX, E. Sept. 9, 1935, No. 25015. [Classes 124 and 145 (ii)] [Also in Group XXIV] Consists in means for converting rotary into reciprocat-# ing motion and for producing combined reciprocating and rotary motion. A shaft a, Fig. 1, held against rotation but capable of moving axially, carries an integral eccentric portion b on which is rotatably mounted a sleeve c, a ridge f on the eccentric preventing relative axial movement of the sleeve. The sleeve has inclined faces c<1> which bear against corresponding inclined faces d<1> of relatively massive ends d united by a sleeve e. If this sleeve be rotated, the shaft a is given a reciprocating motion. In a practical form, Fig. 4, applicable to saws and other tools requiring to be reciprocated, the sleeve e is enclosed in a tubular housing h and the sleeve c is mounted on an eccentric member. b on a shaft a which is secured to a tool-holder o. The ends d have extensions i, k running in ball bearings l in members m, n secured to the housing h. In Fig. 6, the shaft a is fixed as regards both rotation and reciprocation and fluid-pressure is adapted to be applied to the outer faces of the ends d which then reciprocate and rotate, this movement being given to a shaft r. In a modification, the shaft a may be rotated to produce a reciprocation of the end pieces d. Further, with the shaft a fixed axially, both this shaft and the sleeve e may be rotated at different relative speeds to produce different rates of reciprocation of the sleeve e. The end pieces d being set 180‹ apart and being of relatively great mass, balance is obtained, and vibration due to reciprocation is greatly reduced.

Title: Disc brake with automatic adjuster mechanism
IPC: F16D65/14
Filed: 1972-05-30
Abstract: 1327558 Automatic wear-adjusters in spottype disc brakes BENDIX CORP 30 May 1972 [25 June 1971] 25297/72 Heading F2E In a spot-type disc brake having a caliper 22, slidably mounted on a torque-taking member 24 and including a housing 28 defining a bore 30, and actuating means located within the bore, the actuating means includes an extensible member having a pair of relatively-movable elements 32, 34, a cam plate 50 rotatably mounted in the bore for sliding the extensible member upon rotation of the cam plate, and a clutch spring 66 between the cam plate and one of the relatively-movable elements (the adjusting screw 34), the clutch spring permitting relative rotation between the cam plate 50 and screw 34 when the brake is actuated, but joining screw 34 for rotation with cam plate 50 if the latter rotates beyond a certain angle when the brake is released. Brake operation.-Cam plate 50 is rotated by a lever attached to it, operated by an air actuator or cable, whereupon balls 56 ride up in recesses 52 in the cam plate 50 and recesses 54 in a partition member 48. Cam plate 50 therefor forces (via bearings 58) nut 34 and piston 32 to the left to apply friction pad 18, and the shaft assembly 44, 64, 62, to which cam plate 50 is secured, twists and compresses a torsion and compression spring 60. Clutch spring 66, in the form of a coiled spring located against shoulder 68 in part of bore 36 of screw 34, has a tab 69, Fig. 2, accommodated in a slot 70 of an annular boss 72 on the left-hand face of cam plate 50, and if cam plate 50 is rotated through an angle no greater than A, Fig. 2, the spring 66 is not affected. Wear-adjusting.-If, owing to friction-pad wear, cam plate 50 is rotated through an angle greater than A during brake application, end 74 of slot 70 contacts tab 69 of clutch spring 66 when angle A has been turned through, and because at this stage the brake is partially applied, the pressure between threads 38 and 40 prevents relative rotation between piston 32 and screw 34, so clutch spring 66 is rotated relative to screw 34 (e.g. through angle B). On brake release, cam plate 50 first rotates through angle A, and because at this stage the brake is partially released, pressure between threads 38 and 40 is relieved, so clutch spring 66, whose outer diameter is slightly increased during the present direction of rotation, frictionally engages screw 34 and entrains it with cam plate 50, so the length of the extensible member 32, 34, is increased, by an amount equivalent to angle B.

[Class 135] A controlling device for internal combustion engines for example the automatic control of the fuel supply in dependence on the density of the combustion air includes a pair of cam surfaces and a follower which can be transferred from one to the other for working with a rich fuel-air mixture or a poor fuel-air mixture. As shown in Fig. 1, a controlling disc 5 has a slot the sides of which provide two cam paths 6, 7 the former corresponding to the rich mixture and the latter to the "poor" mixture. These curves are alternately engaged by a feeling pin 8 carried by a floating lever 2 which is connected to an air-density reservoir capsule at 1 and to the control valve 4 of a servomotor at 3. The servomotor controls the fuel quantity and, for instance by rack and pinion, turns the disc 5. The pin 8 is kept in engagement with one or other of the curves 6, 7 by coil springs 9, 10 alternately compressed by movement of a frame 11 along a guide rod 12 under the control of a lever 13. Outside the range and corresponding to the sustained power range, the slot narrows to the width of the pin 8. The controlling disc may be arranged in the primary impulse to the servomotor instead of in the restoring mechanism as shown. In a modification, the pin 8 is changed over by a double-acting piston controlled by a piston valve. A similar pair of cams may be employed in a control system for controlling the ignition burning in dependence on the changing pressure.
