Title: Ball throwing machine
IPC: A63B69/40
Filed: 1963-11-11
Abstract: 984,066. Ball projectors. AMERICAN MACHINE & FOUNDRY CO. (AUST.) PTY Ltd. Nov. 11, 1963 [Nov. 23, 1962], No. 44389/63. Heading A6D. A ball projector comprises a throwing tube 11 mounted at the free end of a shaft 31 extending laterally from the upper end of a pilar 21 on a wheeled frame 16. The shaft 31, together with the tube 11, is rotated by a motor mounted on the frame, the speed of rotation being variable by means of a handle 41, operation of which alters the effective diameter of a variable diameter pulley in the transmission system between the motor and the shaft 31. Balls are fed into the tube via apertures 45 and 44 in the frame and tube respectively, and are retained therein by a rod 47 on one side of the aperture 44, and a pivotally mounted arm 48 mounted on the tube on the other side of said aperture. The arm 48 is normally held by a spring-urged catch 53 (also mounted on the tube 11) in the position shown in Fig. 2, wherein an extension 49 of the arm projects through a slot in the wall of the throwing tube, to retain a ball in place therein. In order to release the catch and thereby free the ball for projection from the tube, an extension 57 of the catch cooperates, as the tube 11 rotates, with a projection 59 which is carried by a cylinder 61 slidably and rotatably mounted on a stub shaft extending laterally from the pillar 21, the cylinder being moved at will relative to the stub shaft by manipulation of the handle 62. Thus by means of the handle 62 the projection 59 may be slid into and out of the path of the catch extension 57, and may be rotated relative to the stub shaft to alter the angle of projection. A finger 77, and adjustable plates 74, 75 are provided at the outlet end of the throwing tube to vary the pin imparted to the projected ball. The pillar 21 preferably comprises two relatively rotatable coaxial tubes so that the direction of projection may be varied, and the coaxial tubes may be telescopic to provide a means of varying the height of the apparatus.

As shown, the tapered end of tube 10 is wedged into a disposable tip 40. The maximum engaging force is that exerted by compression spring 33 when the end of the movable sleeve 37 meets the flange of tip 40. The plunger assembly, comprising piston 21 fitted into a finger actuated cap 22, is depressed until flange 25 strikes shouder 26 expelling a volume of air from tube 10. The tip 40 is then inserted into the liquid and the plunger is released. Compression spring 24 moves the assembly to the position shown drawing a volume of liquid into the tip. After discharge, the tip is removed by holding sleeve member 30 and pushing grip 12 to compress spring 33, retracting tube 10 within sleeve 37 until the tip strikes sleeve 37 and is pushed off.

Title: A demodulator for detecting the envelope of a single-polarity pulsating voltage

Filed: 1969-09-17
Abstract: 1,254,916. Pulse demodulator. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTITUT KRIOGENNOGO MASHINOSTROENIA. 17 Sept., 1969, No. 45791/69. Heading H4L.  A demodulator for a train of amplitude modulated single polarity pulses, comprises a capacitor 1, charging through a transistor 2 and discharging through a transistor 3. The first pulse of the shown train renders transistor 2 conductive whereby capacitor 1 charges up to the pulse's amplitude. Transistor 3 is rendered conductive by a pulse from bi-stable means 5; which is triggered, in its enabled state by pulses from generator 11 synchronous with the pulse train pulses. A transistor 7 is rendered conductive synchronously with transistor 2 and disables bi-stable means 5, whereby capacitor 1 cannot be discharged through transistor 3 when transistor 2 is conductive. The charging up of the capacitor is repeated for the second and third pulses. With the fourth however the pulse amplitude is less than the potential on the capacitor and transistors 2 and 7 do not conduct. Means 5 is thus not disabled and the fourth pulse from generator 11 triggers means 5 to render transistor 3 conductive. Capacitor 1 rapidly discharges such that the voltage of the fourth pulse is rapidly reached and transistor 2 conducts. Capacitor 1 thus charges up to the amplitude of the fourth pulse. This process is repeated for the fifth pulse. The voltage across capacitor 1 thus follows the pulse amplitudes.
