Title: Driving power transmission mechanism
IPC: B23Q5/04
Filed: 1974-02-21
Abstract: 1467265 Toothed gearing MITSUBISHI JUKOGYO KK 21 Feb 1974 [28 Feb 1973] 8015/74 Heading F2Q [Also in Division B8] A final stage drive system for the wrist of an industrial robot or automatic machine such as a milling cutter or indexing machine wherein an output sleeve y, can be turned about longitudinal and transverse axes YY, XX, by rotating respectively first and second input shafts y 2 , y 3 , includes irreversible worm gearing y 4 <SP>111</SP>, x 1 <SP>111</SP> and x 3 <SP>11</SP>y 1 <SP>1</SP> in each respective drive path, whereby output vibration is not transmitted to the input shafts. The output sleeve y 1  is carried in a bearing 13 in a casing part x 1 , which can turn about the X axis in a bearing 5 in a main easing part 2, and is rigidly secured to the worm wheel x 1 <SP>111</SP> for rotation about the X axis when that worm wheel is driven by the input shaft y2 through spur gear pair y 2 <SP>1</SP>, y 4 <SP>1</SP>, parallel shaft y 4 , Fig. 4 (behind the worm wheel) and worm y 4 <SP>111</SP>. The worm wheel y 1 <SP>1</SP>, for rotating the output sleeve y 1  about the Y axis in the casing part x 1 , is driven by the input shaft y 3 , through bevel and spur gears y 3 <SP>1</SP>, x 4 <SP>111</SP>, x 2 <SP>111</SP>, freely mounted sleeve x 2 , spur gears x 2 <SP>1</SP>, x 3 <SP>1</SP> (Fig. 3) and worm x 3 <SP>11</SP>. Although X-axis rotation is independent of Y-axis rotation, the latter causes some X-axis rotation due to planetation of the spur gear x 1 <SP>3</SP> about x 2 <SP>1</SP>, and a correction, not described, may be introduced to compensate for this interdependence.

Title: Improvements in or relating to pulse-timing systems
IPC: G06F5/01
Filed: 1956-03-14
Abstract: 799,691. Pulse delaying circuits. SIEMENS & HALSKE AKT.-GES. March 14, 1956 [April 6, 1955], No. 8016/56. Class 40 (6). A pulse delaying system comprises a delay element to which the pulse signal to be delayed is applied and the output of which controls a gate circuit so that a pulse appears at the gate output only during the duration of a predetermined one of the pulses of an auxiliary pulse train which is also applied to the gate. Fig. 1 shows a delay device in which the pulse signal to be delayed, Fig. 2, l, is applied from terminals K1, K2 to a differentiating circuit C1, W1, R1 which produces an output pulse Fig. 2, m, the leading edge of which decays rapidly due to rectifier R1 conducting. This voltage is applied via rectifier R2 so that only the negative going trailing edge charges capacitor C2 and the waveform as shown in Fig. 2, n, is produced at the grid of discharge tube 1 so that tube 1 conducts only for the duration of the next following pulse in the auxiliary pulse train applied at terminal K3. The inverse of this voltage is applied to the gate R3, R4, W4, W5, W6 and C3, C4, which produces an output pulse at terminal K4 only when both rectifiers R3, R4 are simultaneously non-conductive, i.e. only for the duration of the next following pulse in the auxiliary pulse train at K3. Thus the pulse at K4 is a delayed version of the input pulse at K1 K2. In a modification capacitor C2 discharges through resistors W3, W1 instead of through resistor W2.

[Also in Group XXXVI] In an arrangement for evaluating signal currents of different values such as the characterization of digits in a telephone system, there is provided at the receiver a plurality of magnetic devices EW1, VW1, AW1; EW2, VW2, AW2; EW3, VW3, AW3, in each of which a comparison is made between a magnetic flux of constant value provided from a source U and a magnetic flux generated by the current to be evaluated in line L, the currents being switched on or off by a transistor switch TR1 to effect the comparison and produce an output pulse in one or more output windings AW1, AW2, AW3 according to the current value. The pulses are applied to trigger bi-stable circuits TK1, TK2, TK3, through transistor amplifiers V1, V2, V3, when a second transistor switch TR2 is rendered conductive, a switch T being provided to reset the bi-stable circuits. Rectifiers EG1-EG3 decouple the different current value stages, and rectifiers AG1-AG3 short circuit pulses not required for evaluation so that the bi-stable circuits respond only to one polarity of current difference.

Abstract: 451,490. Vehicle spring-suspensions. PORSCHE GES., DR. ING. H.C.F., 24, Kronenstrasse, Stuttgart, Germany. March 18, 1936, No. 8093. Convention date, April 6, 1935. Addition to 424,452. [Class 108 (ii)] The construction described in the parent Specification, in which a half axle is secured to a torsion spring which is disposed in the theoretical axis of oscillation of the half axle, is modified so that the torsion spring will restrain resiliently the relative horizontal movements of the wheel particularly in the direction of travel. The wheel 1 is carried by a half axle 2 and a rearwardly directed strut 2<1>, the half axle being pinioned to one end of the torsion spring 8 and the strut being rotatably mounted on the other end of the spring 8 by means of a rubber bush 9. The ends 13, 13<1> of the spring are mounted in rubber bushes 19, 19<1> clamped in two-part members 11, 11<1> secured to the central frame member 7. Horizontal shocks H in the direction of travel would transmit stresses to the torsion spring and cause it to bend in directions which would be opposite at opposite ends forming a nodal point intermediately. A third bearing 19<11> is mounted at this point so as to resist shocks in the direction of S. This bearing is adjustable longitudinally in a slot 33 in the central member 7. The end of the spring is anchored by a lever 35 and bolt 36, 37.

Abstract: 574,920. Potter's jiggers. JOHNSON, J. A. May 8, 1944, No. 8664. [Class 87 (i)] [Also in Group XXIV] Consists in connecting and disconnecting arrangement for a friction drive particularly applicable to a potter's jigger. To a motor shaft 11, Fig. 1, is keyed at 11a a sleeve 10 to which is secured by screws 13 a disc 12 the lower face of which serves as a friction surface. A ball bearing 14 is located between a flange 10a of the sleeve 10 and a flange 15a on one half 15 of a split pulley the other half 16 of which has a renewable friction facing 17. A belt lies in the groove 19 and, when it is tightened, it forces the facing 17 against the disc 12 whereby the drive from the motor 20 is transmitted through the shaft 11, disc 12 and pulley to the part to be driven. On slackening the belt the facing 17 is disconnected from the disc by gravity or a spring. In a potter's jigger, Figs. 2, 3, the motor 20 drives through the disc 12, the pulley 15, 16, as before, and a belt 22 drives a pulley 21a on the jigger spindle 21. The motor is mounted on a shaft 23 which can be rotated by an arm 24 actuated by a push-rod 25 against the pull of a spring 27 which serves to return the parts to slacken the belt and stop the drive. A brake shoe 28 on the motor bracket 30 is adapted to engage a disc 29 on the jigger spindle when the parts are returned by the spring 27, and to be released therefrom when the motor is turned to tighten the belt. As an alternative, the V- pulley may be driven by the belt to drive the disc.
