Title: A variable speed rope gearing for transmission of motion
Inventor: NILSMAR NILS OLOF
IPC: F16H9/08
Filed: 1950-04-06
Abstract: 670,924. Variable-speed gearing. FRASTAD, O A. April 6, 1950 [April 13, 1949], No. 8724/50. Class 80 (ii). In variable-speed rope gearing the driving and driven shafts 11, 12 are provided with oppositely arranged pairs of conical pulleys 1, 2 each pair having a separate driving rope or ropes 3 so that a parallel drive is obtained. The ropes are tensioned and guided, and shifted laterally to vary the speed ratio transmitted, by sheaves 4 on shafts 14. When two ropes to each pair of pulleys are used they cross over each other so that one runs on the larger diameter of both pulleys and one on the smaller diameter and the sheaves 4 are arranged to tension them separately.

Title: Improvements in golf-practising devices
IPC: A63B69/36
Filed: 1926-04-07
Abstract: 272,317. Goldsworthy, W. J. April 7, 1926. Measuring the force of a blow.-A device for use in practising golf comprises movable means actuated, through intermediate connections, by the head of the player and adapted to be locked until released by the impact of the player's club against an elongated blow-receiver. The blowreceiver is secured to the ground at one end and is separably connected to a pin projecting from a revolvable spindle which actuated a pointer or a revolution counter to determine the force of the blow. The player's cap 25 is connected to a knotted cord 27 passing over the curved and serrated edge 6 of a pivoted plate 5. A weight 28 keeps the cord taut, and the plate 5 is supported by a rod 7 resting on an abutment 30. A foot 9 on the rod 7 lies beneath a pivoted bar 11 which is normally prevented from rising owing to the presence of the obstructing end of the blow-receiver 14 passing through an eye 13 in a keeper 12. The blow-receiver, in the form of a pliable cord or strap, is anchored to the ground by a pin 15 and has an eye fitting loosely over a pin 17 projecting from a. screw-threaded spindle 16 bearing a fly-wheel 19. A slidable index 22 moves over a scale 23 when the spindle revolves, or some other form of revolution counter may be provided. In using the device, the player strikes a ball 24 of cotton, wool, &c., and is prevented from raising his head during the first part of the stroke owing to the locking action of the knotted cord against the teeth on the plate 5 and to the clamping action of the bar 11. After striking the ball, the club hits the blow-receiver 14 and draws it out of the orifice 13 and off the pin 17 thus liberating the bar 11 and pivoted plate 5 to free the head of the player, and also causing the spindle 16 to rotate and give an indication of the force of the blow.

Abstract: 1374699 Photo-electric apparatus SOC ANON AUTOMOBILES CITROEN 1 March 1972 [2 March 1971] 9454/72 Heading G1A Photo-electric apparatus is arranged to produce an electrical signal when two independent parameters attain a predetermined relationship. The apparatus of Fig. 1 indicates when two angular velocities reach equality and can be adpated to indicate other relationships. The respective angular velocities of two rotating shafts are converted by devices C 1 , C 2  (comprising magnetic drums 5 within spring biased metallic cups 6) into angles A 1 , A 2  of rotation of shafts la, 2a. Mounted on shaft 2a, to rotate therewith, is an arm 8a having a cylindrical sector plate 9a carrying a photo-cell, photo-diode or photoresistor 4a. The other shaft 1 a carries a similar arm 13 with a screen 1la having an aperture 12a. Lamp 3a is mounted on the axis of shafts la, 2a. The arrangement is such that whatever the angular position of photo-cells 4a, when equality between A 1  and A 2  is reached, the aperture 12a allows light to reach the photo-cell to provide an output signal. By arranging a plurality of detectors at different angular positions on the plate 9a, other predetermined relationships between the angles A 1 , and A 2  and thus the velocities of original shafts, may be indicated. A typical application is in the determination of the correct time for coupling of a synchronous motor to a system. Another application envisaged is one in which the two parameters are the speed of rotation of an internal combustion engine and the angle of opening of the throttle, respectively.
