Title: Psychological training device
Inventor: BARTHOL RICHARD P
IPC: A63B69/36
Filed: 1969-04-01
Abstract: 1,216,031. Training device. R. P. BARTHOL. 1 April, 1969 No. 17052/69. Heading A6D. In a training device comprising a bat and ball in combination, the bat has a longitudinal bore 17, one end of which is closed by a screw plug 18. The other end connects to a smaller bore 19 which carries a sleeve and pin type electrical coupling 21 which connects with a cable and thence to a power supply. The components housed in the bore 17 include an impact switch 25 and a flash tube 26. When the bat hits a ball the impact will cause the movable blade 42 of the switch 25 to move into contact with either blade 39 or 40 thereby completing the circuit and causing the flash tube to momentarily flash. A transverse bore 27 extends from the bore 17 adjacent the flashtube and has in it a glass disc 31. Thus if the batter is looking at the glass disc at the moment of impact he will see the flash and his attention will therefore be focused on that spot. In a second embodiment, the invention is applied to a golf tee, comprising a stand (82) for a ball (73) connected to a rotatable blade (81) having a contact finger (95). When the ball is hit off the stand the blade (81) rotates bringing the contact finger (95) into contact with one of two plates (92 or 93) thus completing the electrical circuit and causing the bulb (102) to flash momentarily.

Abstract: 1,147,224. Variable speed gear. ZAHNRADERFABRIK RENK A.G. 22 April, 1966 [24 April, 1965], No. 17819/66. Heading F2D. [Also in Division H2] The ring 5 of a sun-ring planetary gear 3, 4, 5, is controlled by a variable speed electric motor-generator 10 through a one-way clutch 7, a brake 8, and a pinion 6 to adjust the output speed of the gear. With the brake 8 applied and the motor 10 disengaged, the ring 5 is prevented from rotating in the direction of the power take-off sun gear 4 by the clutch 7, giving a fixed reduction ratio. On engaging the motor 10 the clutch releases automatically to allow the ring to be driven, increasing the output speed. On disengaging the brake 8, the ring gear 5 may be braked by the motor 10 acting as a generator to decrease the output speed. Two such trains may be connected in parallel, Fig. 5, power from a single motor (1) driving the trains through power-distributing gear (12). Each motor (10) is connected to its pinion (6) by a disconnecting coupling (13), and brakes (14) are provided between the output sungears (4) and each processing machine (11), to prevent power being transmitted to a defective machine (11) whilst allowing the other machine to be driven. A single processing machine (11), Fig. 6, may be driven by the two superimposed trains, which are followed by a power-collecting gear (15). The planetary gear may drive a boiler-water feed-pump or ventilators.

Title: Improvements in and relating to electric supply meters
IPC: G01R11/56
Filed: 1934-06-18
Abstract: 437,761. Supply meters. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. June 18, 1934, No. 18003. Convention date, June 16, 1933. [Class 37] An electric meter is arranged to cause a current impulse or current interruption in a circuit containing a relay each time a predetermined quantity has been consumed, and if the consumption has taken place in less than a predetermined time a disc, which is normally rotated at a constant speed, co-operates with the relay to operate a recording device. In the arrangement shown in Fig. 1, the meter 1 actuates a contact device 2 each time the predetermined quantity is consumed. A disc 4 carrying a conducting segment 41 is driven at constant speed by clockwork or by a synchronous motor 6 through a friction clutch 11 and resetting device 7. If the impulse due to the closing of the contact 2 arrives while a brush 5 is still on the segment 41, the relay winding 8 is energized and advances a counting mechanism 9, but if the time taken to consume the fixed amount is longer than the predetermined time, the brush 5 will have reached the insulating portion 42 of the disc and the winding 8 is not energized. After each closure of the contact 2, the disc 4 is returned to its zero position by the return device 7, which is released by a winding 10, arranged to have a time delay with respect to the winding 8. In a modified arrangement, Fig. 2 (not shown), the disc has several conducting segments connected through slip rings to windings actuating separate counting mechanisms corresponding to different time intervals. In another construction, Figs. 3<a> and 3<c>, the disc 12 is driven by the movement 6 through a coupling 16 which is disconnected every time an impulse is received by the winding 17, the disc 12 being returned to its initial position by a spring 14. If the impulse arrives during the first part of the revolution of the disc, the return movement is effected in the backward direction, and a striker 121 on the disc actuates the arm 123 of a counting mechanism. If the impulse arrives in the later part of the revolution, the return movement of the disc is effected in the forward direction and the arm 123 is not actuated. The apparatus may be provided with means for giving a signal when the excess counting mechanism is actuated. The periodic succession of impulses may also be recorded on a moving paper strip with time divisions marked by perforations.
