Title: Improvements in system for recording television images motion picture film
IPC: H04N5/84
Filed: 1951-04-30
Abstract: 695,235. Television. RAIBOURN, P. April 30, 1951 [May 18, 1950], No. 10117/51. Drawings to Specification. Class 40 (iii). The invention relates to a modification of the system for producing a record of a television transmission on cinema film described in Specification 672,877, wherein the cine-camera operates at 24 frames per second while the television-picture recurrence frequency is 30 c/s., the television signal being, by means of a blanking waveform derived by means synchronized by the received synchronizing signals, reproduced on the screen of a cathode-ray tube for successive periods of <SP>1/</SP>30 sec. separated by intervals of <SP>1/</SP>120 sec. during which the cathoderay beam is switched off so that the cathode-raytube screen may be photographed directly by the cine-camera to obtain a record which comprises one complete television picture per film frame. In the present invention, the cinecamera and the means for synchronizing the blanking waveform are controlled by an independent 60 c/s. power source, instead of by frequency-division of the horizontal synchronizing pulses, so that the blanking signal and motion-picture frame rate are synchronized with one another while not necessarily bearing any predetermined relationship with the television picture recurrence rate.

Title: Improvements in and relating to hydro-electric servo mechanisms
IPC: F15B9/09
Filed: 1959-03-24
Abstract: 908,347. Automatic control systems. SOC. D'APPLICATIONS DES MACHINES MOTRICES. March 24, 1959 [March 24, 1958], No. 10175/59. Class 38 (4). In a hydro-electric servo-system a torque motor controls the valve distributer of an hydraulic device and voltages are fed back in dependence on the output movement of the hydraulic device and the speed and angular displacement of the torque motor. The invention may be applied to an aircraft automatic pilot in which the control signal is supplied by a gyroscope pick-off. In Fig. 3, a variable inductive pick-off 20E supplies an alternating voltage signal to an amplifier 11, the output of which energizes a torque motor 5 operating the control valve 12 of an hydraulic jack 14. A rate signal developed by a generator 38, operated with pick-off 20E, is also applied to amplifier 11. A variable inductive device 20S, operated by the jack, applies a positional followup signal to the input of amplifier 11. Feedback signals representative of the speed and acceleration of the jack are respectively developed by a variable inductive device 20A and a generator 9 coupled to the control valve. The variable inductive devices may share a common housing with associated rate generators. Duplication of windings for reliability is referred to.

Abstract: 569,942. Punching; dimpling; riveting. MILES AIRCRAFT, Ltd., (formerly PHILLIPS & POWIS AIRCRAFT, Ltd.), McQUE, G. H., RESTALL, J., and NEWMAN, J. W. Aug. 24, 1943, Nos. 10246/43 and 12857/44. [Class 83 (iv)] [Also in Groups XXVI and XXIX] A tool for use in dimpling metal and other sheets, applicable also for use in riveting is operated by fluid pressure applied to a series of pistons arrangec in tandem on a common piston rod. The piston anc cylinders are built-up from a series of connected elements to enable the power of the machine to be adjusted as required and to avoid the use of large dia meter cylinders. Cylinder sections 1 are connected by screwed members 3 serving as ends and provided witl packing 6 for the rods 5 also in sections, each sectior mounting a piston 2 with cup leather packing 7. The cylinder section nearest the work carries an extension, screwed at 31 to carry a yoke 30 secured in position by a lock nut 32, and fitted with a guide 9 for the first section 35 of the piston rod which is tapped to receive the shank 34 of the dimpling punch 33 provided with a locating spigot 38 which may be designed to punch the hole. The die 39 has a screwed mounting in the yoke. The piston rod is hollow to pass pressure fluid and is ported at 8 to supply fluid behind each piston, the cylinder space on the forward side of each piston, except that most remote from the work, being permanently ported to the atmosphere at 8a. The final cylinder section has a double-acting piston and is ported at 22, 25. Fluid is supplied at 13 to a piston valve 11 controlled by a press button 12. In the position shown in Fig. 2 pressure fluid passes by ports 14, 16 to the space between the lands ,18, 23 and thence by ports 19, 21, 22 to the port side of the rear piston, effecting the return stroke of the punch and maintaining it in its rear position. The rear of the piston exhausts via the port 25 to the space 29 below the land 18 ported to atmosphere at 28. Movement of the valve to an intermediate position in which the land 23 closes the port 19 and the land 18 the port 25 causes the pistons to be held in any position to which they may have been moved. Complete depression of the valve exhausts the front of the rear piston by connecting the port 19 to the space between the lands 26, 23 ported at 27 through the valve stem to the space 29. At the same time the space between the lands 23, 18 connects the supply port 16 with the port 25 and pressure is admitted behind all the pistons to effect the working stroke. The punch 34 may be replaced by a rod 41, Fig. 6, to engage the countersunk head of the rivet, the die 39 being replaced by a snap 42.

Filed: 1975-03-13
Abstract: 1500162 Aerials INTERNATIONAL STANDARD ELECTRIC CORP 13 March 1975 [14 March 1974] 10576/75 Heading H4A Radio frequency primary aerials 1a, 1b producing a rotating radiation pattern, such as used in TACAN systems, may be symmetrically and vertically stacked so that the radiation below the horizon is reduced to zero where the side lobe maximum of a single primary aerial would occur and the main beam is maintained at the same elevation as a single primary aerial (Figs. 3a and 3c, not shown), the degree of modulation being maintained approximately constant over the operational elevation range of the system. As claimed, a rotating pattern compound aerial comprises at least two elementary aerials 1a, 1b each having an active antenna 2a, 2b normal to and coaxial with a circular ground plate 3a, 3b and a circular ring of parasitic elements 5a, 5b coaxial with the active antenna; radio frequency energy supply means and control means for switching the parasitic elements in turn, the ground plates of the primary aerials being spaced parallel and coaxial, there being means for equally dividing the radio frequency energy supplied between the active antennas with a phase shift of #/n where n is the number of primary aerials. One embodiment described is a two-tier TACAN system (Fig. 1) in which the radiation pattern is stated to be undisturbed by the feed (Fig. 7). Radio frequency power is equally divided between frusto-conical active antennas 2a, 2b of length #/4 to #/2 where # is the wavelength corresponding to the radio frequency used. The antennas are fed through different lengths la, lb of semi rigid coaxial cable to give the required phase shift. The antennas are insulated from their respective ground plates by dielectric rings 18a, 18b the heights of which provide impedance matching to cables 10a, 10b. Ferrite rings 19 decouple the antenna 2b from tube 13. Parasitic switching circuits located in spaces 15-1, 15-2 are controlled through leads 14-1, 14-2. Other embodiments (not shown) include a three-tier TACAN system.

Title: Recovery of paper fibres from paper-containing refuse
IPC: B07B4/02
Filed: 1975-03-14
Abstract: After separating out the non-reclaimable waste components, the remaining fraction comprising paper and plastics is further separated into paper and plastic particles by air classification. Before this further separation is carried out, the material is moistened, the paper, but not the plastic material, absorbing moisture. The specific weight of the paper, which before moistening corresponded approximately to that of the plastic material, is thereby increased to such an extent that a reliable separation in the air classifier can take place. An optimum separating effect can be obtained at approximately 40-60% moisture content of the paper. The device is designed such that a moistening device (21) is arranged downstream of a first air classifier (11) and of a screen apparatus (18) which sorts out relatively large waste parts and by means of which the aforementioned fraction is sorted out. Downstream of said moistening device (21) there is a second air classifier (24) which effects the paper/plastic separation. <IMAGE>
