Title: Improvements in very high gain travelling-wave valves
IPC: H01J25/38
Filed: 1949-08-03
Abstract: 668,334. Travelling-wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Aug. 3, 1949 [Sept. 17, 1948], No. 20265/49. Class 39 (i). A travelling-wave amplifier comprises a plurality of separate systems, each comprising a cathode, an electron beam, and a retardation line, the wave travelling along the retardation line of at least one of the systems interacting with the beam of the next system so that the total gain of the valve is divided between a number of stages operating in cascade. In one form, Fig. 1, electron beam F1 from cathode K1 amplifies the input wave applied to helix H1 and the amplified wave modulates a second beam F2 from cathode K2 which generates a still farther amplified wave in helix H2. The beam F2 passes outside the helices H1, H2 and may or may not be annular. The cathode K2 may be correspondingly annular, broken if necessary by the quartz rod or rods T1. Coatings of high-frequency loss material R1, R2 on the quartz rods T1, T2 or on the wire of the helices H1, H2 terminate the helices non-reflectively and the helix H1 may be provided with further loss material at A. Magnetic focusing is employed. In a modification, Fig. 2 (not shown), beam F2 passes first between helix H1 and the envelope which is of metal and then inside helix H2 and interacts with the transverse field component to produce gain. The collectors C1, C2 of Fig. 1 are combined into a single collector to facilitate cooling of, and D.C. supply to, collector Cl. The devices may have more than two amplifying stages in cascade. The devices may be used as repeaters in transmission systems. Prior art repeaters comprising a number of travelling-wave tubes connected in cascade are referred to.

Title: Improvements in character indicators

Abstract: 951,758. Electric selective signalling systems. J. HANDLEY. Sept. 14, 1960 [June 15, 1959], No. 20334/59. Heading G4H. In a remote display system of the type in which a display unit Fig. 1 hunts for a combination of markings on a plurality of leads and then displays the appropriate character, the different characters being carried on flaps 1,a monitor display device is provided so that the operator having set the remote indicator can operate a switch and cause the remote indicator to transfer its indication to the monitor unit whereby the operator can make a visual check as to whether or not the correct character is being displayed. Control of the remote indicator is effected by keys K1-K6, Fig. 4, lack of agreement between the key settings and contacts 22-27 at the remote indicator energizing a relay R/1 which causes stepping of the remote indicator until agreement is reached. Once the remote indicator is set the operator can actuate a key K7 which causes,via contacts C1-C6, contacts 22-27 to be connected to contacts 30-35 of a monitor indicator instead of to keys K1-K6. The monitor indicator then steps under the control of the remote indicator so that the operator can check the operation of the remote indicator.

Abstract: 425,894. Master control of D.C. motors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and CROFT, E. H., c/o General Electric Co., Witton, Birmingham. July 20, 1933, No. 20493. [Class 38 (iii)] Regenerative braking; field control.-In a control system for a compound - wound traction motor 1 in which forward movement of a master controller 26 effects acceleration of the motor solely by means of armature and field resistance control and in which backward movement of the controller from its full speed position effects strengthening of the shunt field excitation 3 for regenerative braking, the controller is provided with contacts 41, 42 bridged only during the backward movement to effect an increase of shunt excitation such that for various positions of the controller the shunt excitation is then greater than that obtained in the said positions as the result of forward movement, whereby a strong field is obtained notwithstanding the opposing effect of the series winding 2. The controller contacts 41, 42 cut-out a step of the shunt field resistance 13 which is inserted for all positions during forward movement of the controller. This additional step of shunt field resistance may be cut-out in steps governed either by the value of the regenerated current or by the degree of backward movement of the controller. In a modification, the additional increase of shunt excitation during regeneration is effected by a reverse-current relay.

Abstract: 281,010. Stone & Co., Ltd., J., and Honey, A. E. Aug. 24, 1926. Supplying consuming devices from variable-speed generators. - In an AC heating system for railway &c. vehicles each of the heater switches S is associated with a switch and a resistance H in the exciting circuit of the alternator r so that the strength of the field is varied in proportion to the heating demand. Such resistances may be included in a cable extending through the train. Auxiliary resistances r<1> - - r<3> in the exciting circuit may be controlled by relays j<1> - - j<3> adapted to increase the field circuit resistance in accordance with rise of battery voltage, a centrifugally operated switch g may be adapted to increase the resistance y as the speed of the train increases, and a further relay j<4>, operated by the potential drop in a portion of the exciting circuit, may be arranged to insert a resistance r<4> wherein to reduce the excitation drastically when the heating demand is relatively small or the speed of the train high. The circuits of these relays may be interrupted by an electromagnetic switch under the control of the alternator field current so that they are only operative when the alternator is active; waste of power in the relay coils is thus avoided. Where the exciting current is derived from the lighting installation a calibrating resistance w may be included in the field circuit and a switch arrangement u<2>, f<1> associated therewith provide that the current in the field circuit is controlled in accordance with the conditions of the lighting circuit. The centrifugal switch g may operate a contact q shunting the field by a discharge resistance x at lower speeds.

Title: Improvements relating to scrap-baling press
IPC: B30B9/32
Filed: 1956-07-05
Abstract: 794,000. Baling presses. LINDEMANN, W. July 5, 1956 [Feb. 13, 1956], No. 20892/56. Class 94(1). A scrap baling press includes an open charging trough above the press box in which scrap is given a preliminary compression by a plunger prior to discharge into the box. The press inincludes a main plunger 11 in the box 10, the box having a closeable lid 23, and an auxiliary plunger 14 which compresses and then discharges a scrap bale through an aperture 18, the latter being normally closed by a slide 19. The trough 25 has extensions 41, 42 to guide in scrap fed by a conveyer 45. A plunger 26 compresses the scrap against an upward extension 39 of the press box or against a wall 33 carried by the lid. The plungers 11, 14, 26, lid 23 and slide 19 are all operable independently by hydraulic cylinder and piston means. The plungers 11, 26 have rearward extensions 43, 40 to prevent scrap falling behind them. In operation a charge may be fed into the trough while the lid is open and compressed against the extension 39. The lid 23 is then lowered to press down the charge, cutting edges 29, 32 shearing any protruding portions. With the lid closed the plunger 11 and then the plunger 14 compress the charge further and the slide 19 is withdrawn to permit discharge of the bale by the plunger 14. During this period a further charge may have been compressed against the wall 33. The independent controls permit any of the above operations to be carried out in part and repeated if a charge is difficult initially to force into the press box.
