Title: Improvements in or relating to oscillation mechanisms for irrigation lines
Inventor: HUGGAN JOHN AINSLEY
IPC: B05B3/04
Filed: 1958-07-21
Abstract: 907,291. Crop sprayers; liquid-pressure engines. HUGGAN & CO. Ltd., JOHN. July 20, 1959 [July 21, 1958], No.23268/58. Classes 69 (2) and 69 (3). An irrigation pipe-line is angularly oscillated about its axis by an hydraulic motor comprising a piston within a cylinder 15, control valve 17 and valve operating mechanism 18. The motor is pivoted to a base 10 at 21 and to a crank 14 attached to a tubular member 13, Fig. 3, rotatably carried in a fixed bearing 12 supported by a post 11. Pipe-lines 39, 40 with spray nozzles therealong have their one ends received by clamping rings 64, 65 surrounding the member 13. Water from the pipe-lines is fed from an opening 62 and outlet 61, Fig. 3, to a hose 41 leading to the motor control valve, and waste water from the motor is fed from a valve-controlled outlet 25 of the valve via a hose 42 to a discharge nozzle 43. The control valve connects, through tubes 27, 28 to the upper and lower ends of the cylinder, and the arrangement is such that water is alternatively fed to the opposite ends of the cylinder to drive the motor, and exhaust water is fed to the nozzle 43. The valve is automatically operated by a lever 29 operated by a mechanism 18 comprising a rod 30 passing through the lever and pivoted to the reciprocating member 19. Collars 33, 34 are bolted to the rod, and springs 35, 36 are interposed between the collars and the lever 29 and act thereon at the extreme positions of the piston to move the valve lever from one position to another. The lever is held in those positions by a spring-loaded plunger which engages notches in the lever. The amplitude of the oscillation can be adjusted by adjustment of the collars, and the frequency by the valve 26 in the outlet 25. In a modification water is fed to the pipe-line via a main connection on the bearing member, and the latter carries a filter from which a hose leads . to the control valve.

Title: Improvements in or relating to damping arrangements for resisting variations in the speed of a driven member
IPC: G11B15/50
Filed: 1938-08-12
Abstract: 505,738. Damping arrangements for controlling speed. ELECTRICAL RESEARCH PRODUCTS, Inc. Aug. 12, 1938, No. 23795. Convention date, Aug. 31, 1937. [Class 103 (i)] [Also in Group XXXVIII] An arrangement for maintainiug constant the speed of apparatus, such as film or sound recording, comprises stationary and rotating concentric cups containing a viscous liquid which fills part of the space between their adjacent side walls, the level of the liquid between the side walls being raised by centrifugal force and increasing the resistance as the speed increases. The side walls of the cups may be slanted outwardly and also the space between the cups may be reduced in width towards the top to produce a progressive resistance as the speed increases and vice versa. The surface of the liquid is indicated by the parabolic curve 16 for normal speed and by the curve 18 for an overspeed. Modifications are shown and described in which the cups are cylindrical or in which the surface of the outer stationary cup approaches the inner cup in curve or in which the upper walls of both cups curve inwards. Mathematical formulae are given for calculating the dimensions and characteristics of the cups. A flexible air chamber 30 in the reservoir 26 for the liquid maintains the liquid level constant with changes of temperature. The interior of the cup 14 also acts as a reservoir, the liquid passing through ducts 19, 20. Vanes 21 on the shaft 2 of the cup assist the movement of the fluid. Either cup may be rotated. The cup is driven through springs 8. The shaft 2 is mounted on a ball 24 resting on an adjusting pin 25. In Fig. 2, the damper 15 is shown mounted on the shaft 68 of a vertical sound recording roller 67 driven by the film which passes over sprockets 52, 60, 62 driven by an electric motor through gearing 56, 57, 58, 65. The sprocket 62 is driven through a spring 64. A construction is shown which is rendered quicker acting by arranging a flow of hot water around the damper just below the fluid level at normal running speed and a flow of cold water just above this level, but in the opposite direction to the hot water flow.

Title: Apparatus for obtaining a reproduced still picture
IPC: H04N9/11
Filed: 1973-05-21
Abstract: 1431985 Still picture reproduction TOKYO SHIBAURA ELECTRIC CO Ltd 21 May 1973 [19 May 1972 22 May 1972] 24017/73 Heading H4F A control device, for apparatus which obtains a reproduced still picture from a video film having a plurality of frames in which are recorded picture and pilot signals, said frames being separated by frame margins of a predetermined pitch, comprises a device for scanning the film by a light spot raster and photo-electrically converting light from the film to provide a picture reproduction signal, a circuit extracting a frame margin signal from the picture reproduction signal by detecting the pilot signals therein and a control device for positioning the vertical scanning of the raster in response to the frame margin signals so that the raster coincides with a frame on the film. Luminance and colour signals are recorded in separate frames side-byside on an electronic video recording (EVR) film (Fig. 2, not shown). The colour signal (in the NTSC system) includes a 0 : 9 MHz pilot signal whose amplitude falls to zero only at the frame margin intervals and during flyback periods (Fig. 3, not shown). The frame margin signals are detected by applying the pilot signal amplitude to the base of a transistor whose collector is shunted to ground by a capacitor (Fig. 4, not shown). If the pilot signal amplitude is above zero, the capacitor is discharged through the transistor. At the frame margin and flyback however, the transistor is turned off and the capacitor charges through a resistor. The fly-back period being short produces only a small pulse which can be discriminated against. The raster position control operates as shown in Fig. 5. The film is scanned by a CRT flying spot scanner, whose vertical scanning synch. pulses are applied at a to a monostable 22 whose unstable period is slightly greater than n vertical synch, periods. This first monostable triggers a second monostable 23 whose unstable period is slightly less than one vertical synch. period. The monostable 23 output opens a gate 24 whose second input e comes from the frame margin signal detector. Thus every nth vertical synch. period, the frame margin signal is tested to detect whether it is in synchronism with the vertical synch. pulses of the scanning raster. If not a pulse appears at gate 24 output which operates sample and hold 26. The vertical synch. pulses also trigger a positive sawtooth generator 20 whose output is compared in comparator 21 with a reference level i which controls the scanning raster position. The pulse output from the comparator, triggers a negative sawtooth generator 29 which is sampled by sample and hold 26 when an out-of-synch. frame margin pulse is detected. The output of sample and hold 26 is itself sampled and held at the next vertical synch. pulse by sample and hold 27 whose output provides the control and reference signal i. The second sample and hold may be omitted. The picture signal may be generated by reflection or transmission through the video film.
