Title: Improvements in electron multipliers
IPC: H01J25/76
Filed: 1936-05-01
Abstract: 463,514. Electron multipliers. FARNSWORTH TELEVISION, Inc. May 1, 1936, No. 12396. Convention date, May 7, 1935. [Class 39 (i)] An electron multiplier for use as an oscillation generator or for amplifying electrons produced by thermionic or photo-electric means consists of two perforated plates A, B which act as the impact electrodes and are backed by collector plates 5 attached to leads 10. A central anode consists of a spiral 4. The plates A, B, are preferably of silver, oxidized and then caesium coated. The plates 5 are preferably of carbonized nickel to prevent secondary emission but they may be of tantalum, tungsten or molybdenum. The leads 10 are connected to a tuned circuit consisting of the adjustable condenser 16 and inductance 17 earthed at its mid point ; the anode is biassed by a battery 20. Electrons striking the solid part of the perforated plates cause secondary emission, the secondary electrons passing in a cloud between the two plates A, B ; electro-static or electromagnetic control cause longitudinal displacement of the electrons forming the cloud. Some electrons pass through the apertures and are collected by the plates 5, the distance from plates A, B to the plates 5 and the biassing being arranged that the current produced on the plates 5 will be at 180‹ to the potential on the corresponding apertured plate ; a potential is produced thereby to assist the tuned circuit. Specifications 368,721, 450,138, and 451,724 are referred to.

Filed: 1958-04-21
Abstract: 839,531. Pipe couplings. K. A. C. Ltd. Feb. 16, 1959 [April 21, 1958], No. 12646/58. Addition to 809,803. Class 99(1). An end fitting for corrugated metal tubing 1 having an uncorrugated end portion 2 and an external tubular reinforcement 6, e.g. a metallic braid, comprises an annular sleeve 3 having the internal surface 4 thereof configurated to conform with the external corrugations of the tubing and an annular surface 8 thereon located to engage the exterior of the portion 2 and inclined to the axis of the sleeve, a tubular ferrule 9 having a spigot 10 fitting within the bore of the tubing and an annular surface 12 complementary to the surface 8 and located to engage within the bore of the portion 2 to trap that portion between the surfaces 8, 12, and a retaining ring 15 surrounding the reinforcement to trap the latter between the ring and sleeve, there being means for coupling the sleeve and the ferrule against axial relative displacement to release the portion 2, and means for securing the ring 15 to the sleeve in reinforcement trapping relationship thereto. As shown, the ferrule is formed with a shoulder 13 constituting a stop for a ring nut 14 screwed into the skirt 7 of the sleeve 3 to displace the latter and ferrule axially of one another to draw the surfaces 8, 12 together for gripping the tubing portion 2, and the sleeve has an external, tapered, knurled portion 5 complementary to the internal tapered surface of the ring 15, the latter being drawn into a reinforcement-gripping position by a collar 16 screwed on to the skirt 7. When the tubing is provided with helical corrugations the sleeve is screwed on to the tubing; otherwise, the sleeve is in two or more parts fitted around the tubing. The collar 16, sleeve 3 and nut 14 may be drilled and tapped to receive a locking screw. In a modification, the reinforcement-retaining ring is drawn over and secured to the sleeve by a second ring nut. In further modifications, (a) the sleeve and ferrule are coupled together by complementary screw-threads on these parts, (b) the reinforcement-retaining ring and sleeve are secured together by complementary screw-threads thereon in which case, to prevent the transmission of torque to the reinforcement, the ring may be in two parts, one part engaging the reinforcement and the other part being adapted to rotate relatively to the first part and the sleeve, and (c) the ring is swaged on to the sleeve.

Title: Improvements in or relating to toy aeroplanes or like flying appliances
IPC: A63H27/04
Filed: 1947-05-10
Abstract: 633,010. Toy captive aeroplanes and the like. FABRY, R. May 10, 1947, No. 12692. Convention date, Jan. 21. [Class 132 (iii)] A balance arm has a toy aeroplane or the like fixed to one end and a balance weight fixed to the other end and is pivoted about a horizontal fulcrum on a vertical rotatable spindle which spindle has, fixed thereto, a pulley, round which is passed a cable or cord by which the spindle may be rotated. Preferably the aeroplane is of such a weight that the turning moment exerted by the aeroplane, and the part of the arm on its side of the horizontal pivot, exceeds that exerted by the balance weight and the other part of the arm so that, as the speed of rotation of the spindle decreases the aeroplane is lowered towards the ground. There may be a hook under the plane arranged to carry a message or bomb. As shown, the spindle 5, which is rotatably mounted on a base 8 and is held perpendicular thereto by a brace 7, is rotated by the cord 10. When the spindle is rotated uniformly the aeroplane 1 will fly round in a horizontal plane. If, however, the speed is varied abruptly it can be made to describe a circle in a plane which is inclined to the horizontal. The hook 11 on the underside of the aeroplane is arranged transversely with its point inwards. An imitation message or bomb 14 has a hook 15 on top by which it is hung on the hook 11, on which it tends to remain due to centrifugal force. If, however, the aeroplane is stopped abruptly, when above the horizontal plane containing the horizontal pivot 4, the bomb or message slides off the hook.

Title: Improvements in or relating to tracking means for conveyor belts
IPC: B65G39/16
Filed: 1951-05-30
Abstract: 698,974. Endless belt conveyers. HEWITTROBINS, Inc. May 30, 1951. [June 3, 1950] No. 12703/51. Class 78 (i). [Also in Group XXXIV] The tendency for a conveyer belt to wander laterally on its supporting idlers is corrected by providing each idler with a double pivotal support, one pivot axis extending horizontally and at right angles to the roller axis and the other pivot axis extending vertically, and locating stationary shoe means adjacent but spaced from the roller on opposite sides of the horizontally extending pivot axis for engagement by the roller when this moves about this axis due to the belt wandering from its intended path, such engagement causing the roller to rotate bodily about the vertical pivotal axis to advance the end of the roller toward which the belt is wandering whereby the belt is caused to return to its intended path. In the embodiment shown in Figs. 1, 2, the shaft 8 of the roller 3 is supported on the side walls 5 of a frame 4 which is supported by trunnions 9 on a U- shaped yoke 10 rotatable about a vertical pivot 11. When the belt wanders to one side such as to the left as shown in Fig. 1, it rocks the roller into contact with one of a pair of friction shoes 13 mounted on brackets 14. This causes the adjacent end of the roller to walk forward in the direction of the belt travel, the yoke 10 turning about the pivot 11. The roller thus assumes a skew position to direct the belt back towards the centre of the roller. Lugs 12 restrict the turning movement of the yoke 10. In the embodiment shown in Fig. 4. the roller 16 is provided with a bearing 17 the inner race of which is supported by a pin 20 on a shaft 18, the ends of this shaft being secured in brackets 21 on a frame 22 rotatably mounted on a vertical pivot 23. The friction shoes 25 are supported on brackets 26 which straddle the frame 22 and limit its rotation about the pivot 23.
