Abstract: 599,677. Velocity-modulation tubes. SPERRY GYROSCOPE CO., Inc. Jan. 4, 1944, No. 153. Convention date. Jan. 6. 1943. [Classes 39 (i) and 40 (iii)] A cavity resonator for use in electron discliarge apparatus has end wall portions with apertures through which an electron stream passes, joined by a generally cylindrical boundary wall having a flexible portion so that the end walls can be moved relatively to each other in a direction parallel to the electron beam for tuning purposes. As shown, the resonator 52 has an annular rib 54 to provide the desired flexibility. The bottom end wall of the resonator is mounted in a support 57 to which the cathode assembly 67 is secured. A reflector 601 for the beam is mounted on a tube 60 passing through the seal 61 in rigid relation to the upper wall 49 of the resonator, this unit being connected to support 57 by a flexible part 72 and moved by tuning screw 66. The annular rib 54 acts as a wave trap and may be open at the ends. In an alternative construction, the side wall of the resonator may have an inwardly projecting rib in concertina fashion. Instead of screw 66, tuning may be effected by the thermal expansion of a strut with controlled heating means. A coaxial line' 68 is shown to remove energy from the oscillator, but a wave-guide with a slot-like orifice in the resonator may be used. Specification 599,733 is referred to.

Title: Improvements in or relating to remote control servo systems
Inventor: ORLOFF GEORGE
IPC: G05D1/00
Filed: 1955-01-05
Abstract: 791,055. Automatic steering control systems. BRITISH MESSIER, Ltd. Jan. 4, 1956 [Jan. 5, 1955], No. 358/55. Class 38 (4). [Also in Groups XXIX and XXXVIII] A remote control servo-system comprises a manually operable lever 1 and an automatic control unit 40 which lever and unit can be selectively connected to a controller 6 in a closed loop including a first servomotor 11 and the controlled element which element is also connected to a second controller 20 in a closed loop including a subsidiary servomotor 25 and a second controlled element 27 having a lost motion or spring connection with the manually operable lever 1. As described applied to an aircraft control, the pilot's stick 1 and the autopilot 40 can be selectively connected by a selector switch 5 to the controller 6 which may be an electronic or electromagnetic amplifier. In the first case a signal corresponding to any movement of the stick 1 is transmitted by a potentiometer 3 to the controller 6 which through a line 7 is connected to an electrohydraulic relay valve 10 which controls an hydraulic servomotor 11 operatively connected via a pair of rods 12, a yoke 13, a shaft 14 and a linkage 15 to the controlled element (not shown), e.g. elevators, ailerons, rudders or fluid jets. The shaft 14 carries a potentiometer 16 by which a signal indicative of the actual position of the controlled element is fed back to the controller 6 via the line 17. The controller 6 compares its two input signals and the arrangement is such that the yoke 13 is moved at a rate proportional to the difference between the signals and in a direction to reduce such difference to zero. A signal indicative of the actual position of the controlled element is also transmitted by a potentiometer 18 to the second controller 20 which also receives, via a potentiometer 29, a signal indicative of the position of the yoke member 27 which is connected by springs 31, 32 to the stick 1. The output of the controller 20 depends on the difference between its two input signals and is transmitted by a line 21 to an electro-hydraulic relay valve 24 which controls the subsidiary servomotor 25 which adjusts the position of the yoke member 27 to follow the stick 1. When the auto-pilot 40 is in use the selector switch 5 is positioned so that the first input signal to the controller comes from the autopilot. The servomotor 11 is operated as before to position the controlled element and the subsidiary servomotor 25 operates to move the yoke 27 which through the springs 31, 32 postions the stick 1 accordingly. There may, as shown, be provided means 42, e.g. gust detecting means, for detecting one or more additional external influences and superimposing signals corresponding thereto on the first input signal to the controller 6. Specification 712,329, [Group XXIX], is referred to.

Abstract: 419,494. Moulding pipes. WHITAKER, D., 26, Buckingham Gate, London. Jan. 5, 1934, No. 466. [Class 87 (ii).] A machine for making pipes from concrete, clinker, or other material, comprises a mould 1 having a core 3 and adapted to be placed in an upright position for filling and moulding, the mould being then moved to a horizontal position wherein the pipe 8 is stripped from the core and carried away by a pallet 4 which has formed part of the mould. A number of moulds each with a core and pallet may be provided. The moulds and cores are rigidly mounted on a carrier 5 pivoted at 6 on a vibrating table 7. The moulds are secured to saddle members 5b and the cores have reduced screwthreaded ends 3<a> which are passed through holes in the carrier 5 and are secured by locknuts. The moulds are provided with a drawplate 9 bored to receive spigot bushes 10 adapted to slide on the cores. The draw-plate is formed at each side with pins 11 moving in slotted guides 12 and is provided with lips 15 which engage the pallets 4. Stirrup straps 14 are pivotally mounted at 39 on a transverse frame 13 which connects the ends of the guides 12, and the pallets 4 are held in position by the straps 14. The bushes 10 are so formed as to mould spigot ends on the pipes and the moulds may be fitted with hammer caps 18 shaped to produce socket ends. In operation, the moulds are placed upright and secured to the table 7 by bolts 34. The table may be vibrated by cams 45, and the hammer caps 18 may also be vibrated by this means, or manually, or mechanically by separate means. The carrier 5 is then swung over by a lever 16 so that the moulds are horizontal and the pallets 4 rest on a trolley 23. The straps 14 are swung up to release the pallets and the pipes are stripped from the cores by drawing the pallets and trolley away by ropes 24 secured to the pins 11 or passed round pulleys 47 thereon and operated by a winch 25. The ropes 24 may be formed from one continuous length wound at each end on drums 49 and passed over a series of intermediate pulleys including the pulleys 47. The draw-ropes then operate with an equalizing action on opposite ends of the draw-plate. The moulds 1 may be of thin steel or sheet metal rolled or bent to shape one half or one side of the pipe, the remainder being shaped by the pallet. Longitudinal lips may be provided on the edges of the mould sections 1 to position and guide the pallets. The trolley may run on rails 28 or be otherwise guided. The cores may be slightly tapered and the bushes and hammer caps may be adapted to form square, tapered or other shaped ends.

IPC: D01G19/16
Filed: 1968-01-03
Abstract: 1,213,583. Combing machines. NITTO SHOJI K.K. 3 Jan., 1968, No 522/68. Heading DIN. In combing fibres two rotatable nipper mechanisms each with a pair of similar grips 13, 15 and 26, 27 are provided with means to rotate them in synchronism so that a first tuft of fibres is held in a grip and is combed at its free end by a combing drum; then its free end is gripped in a grip of the other nipper mechanism and its other end released and combed by the combing drum 1, then the tuft is released. A second tuft is gripped in the other grip of the first nipper mechanism as the first tuft is released and is similarly combed, transferred to the other nipper mechanism and released. As shown, the nipper mechanisms each consist of two similarly shaped plates 6a, 6b (Fig. 6) with co-operable jaws 13, 18 and 13', 18' at each end. As the plates rotate about shaft 12 a pin 43 on a guide lever 40 which is secured to the shaft 12 passes through slots 17 in the plates and engages a grooved cam 45. This causes the jaws 13, 18 to engage during half of the rotation and the other jaws 13', 18' during the other half of the rotation. Both nipper mechanisms rotate at the same speed, together and intenmittently through four positions. When in a first position (Fig. 3) jaws 13, 15 are open to receive the end of a lap 50 fed from rollers 5, 5'. The grip is closed and a tuft is separated from the lap as the nipper device turns into a second position (Fig. 2) Where the tuft is combed by rotating comb 1. The nipper device then moves into a third position 3 (Fig. 1) where the tuft is transferred into the grip 26', 27 of the second nipper mechanism while the first nipper device is receiving another tuft from lap 50. The nipper mechanisms then rotate such that both tufts are combed by comb 1, before tuft 50' is pieced on to the combed fleece 53 at the fourth position (Fig. 3) while the second tuft is transferred to the second nipper device and another tuft received by the first nipper device.

Title: Improvements in methods of colour correction in copying photographic colour pictures
IPC: G03C7/18
Filed: 1940-01-11
Abstract: 539,510. Colour photography. KODAK, Ltd. (Eastman Kodak Co.). Jan. 11, 1940, No. 621. (Class 98 (ii)] In the production of a three-colour photographic record, an original is formed comprising three superposed substractive colour component images of which two are processed to gammas such that their ratio is less than unity (which ratio is preferably less than 0.9), and is printed on to another material having three superposed emulsions, the two images corresponding to the first pair being processed to gammas such that their ratio is greater than unity. The gamma of the blue-green image may be reduced in the original and increased in the print. The magenta image may be treated similarly. The gamma of the yellow image in the original may be increased, with or without simultaneous decrease of the gamma of the blue-green image, and the ratio adjusted in the print. The alteration of gamma may be effected by emulsion or processing changes. Reduction of gamma is obtained by (a) reducing the concentration of colour coupler in the developer, (b) increasing the sulphite concentration in the developer, (c) using an additional colour coupler producing a dye image which is partly soluble in the processing solution, and (d) using a competing non-coupling developer. A preferred formula includes o-hydroxydiphenyl as the colour-coupler. In accordance with method (c), 1-amino-8-naphthol-3:6-disulphonic acid may be added to the preferred formula, and in accordance with method (d), metol may be added. The process may also be applied to the dye destruction process by appropriately adjusting the amounts of the dyes in the various emulsions. The process may be applied to three-layer or mixed grain, including doublelayer, material. The materials may be processed by false colour methods, and the original may be a positive, and the print a positive or negative, or the original may be a negative, and the print a positive or negative. Printing filters or printing light of restricted wave-length may be employed. Specifications 440,032, 440,089, 468,560, 475,784, 475,786, 500,611, 500,613, 500,826, 503,752, 503,821, 524,154, 524,554 and 524,555 are referred to.
