Title: Improvements in or relating to cathode ray tubes
IPC: H03B13/00
Filed: 1947-12-16
Abstract: 684,590. Cathode-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Dec. 16, 1947 [Oct. 23, 1946], No. 12600/52. Divided out of 684,552, [Group XL(c)]. Class 39(i) A cathode-ray tube is provided with means for deflecting the beam in one dimension only and includes a first collecting electrode and further collecting electrodes which are so shaped and positioned in relation to the first collecting electrode and to the path of the beam during deflection that normally the beam current is distributed between the first collecting electrode and one of the further electrodes, and that the fraction of the beam current reaching the first collecting electrode varies with deflection of the beam so as to pass through a succession of maxima and minima whose values form two monotonic series having the same sense. The first collecting electrode 4, Fig. 3, may be arranged behind the further electrodes 3 and may be connected within the tube to a deflection plate 2 so that the beam can occupy stable position adjacent one'of the electrodes 3. The electrodes 3 are preferably connected together and so shaped and positioned as to produce a curve of the form shown at 11 in Fig. 2 for the current ia flowing to electrode 4 against the deflection voltage V. In another arrangement, Fig. 4, the first electrode 20 and further electrodes 21 are arranged in the same plane. The tube may be provided with a supplementary collecting electrode on which the beam impinges at a certain deflection and which may be used to generate pulses to move the beam to a further position. The collecting electrodes may be secondary electron emitting.

Patent GB-475474-A (GB)
Title: Improvements in or relating to telegraph exchange systems
IPC: H04L25/04
Filed: 1937-05-04
Abstract: 475,474. Telegraph exchange systems. SIEMENS & HALSKE AKT.-GES. May 4, 1937, No. 12711. Convention date, May 4, 1936. [Class 40 (iii)] In a telegraph exchange system, a regenerator for the telegraph signals, equipment for testing the distortion of the signals, and supervisory apparatus for responding to particular combinations of signal elements, are combined in common apparatus located, for example, at a toll position. In the system shown, the operation of relay ER from spacing to marking energizes magnet AM to start the cam-shaft controlling the regenerator and the distortion testing, and a contact Sta on the shaft operates relay SR to marking. Cam contacts k1 ... k5 are then closed in succession in the middle of the signal-element periods and condensers C1 ... C5 are charged in one or other direction over contact er and winding SR(i) which repeats the signals to the outgoing line. At the end of the fifth impulse, contact k6 operates relay U which first closes contact u6 to premagnetize windings (ii) of relays A ... E to a point just short of operation and then closes contacts u1 ... u5 so that condensers Cl ... C5 discharge through windings (i). Certain of the relays operate according to the direction of the charge on the corresponding condenser and for predetermined combinations close circuits such as that shown for relay AR to operate a bell EW and lamp FL. At the end of the rotation of the cam-shaft, contacts Sto close to operate relay SR to spacing. To test the distortion, a neutral relay R co-operates with cams I and II and causes a glow-lamp Gl to light over normal contact r and contacts ku1 or ku2 if the distortion predetermined by cams I, II is exceeded. The supervisory alarm signals may be arranged to operate only after repeated transmission of a particular combination and may also be dependent on the direction of traffic.
Patent GB-635209-A (GB)
Title: Improvements in automatic bottle capping machines
IPC: B67B3/02
Filed: 1946-04-26
Abstract: 635,209. Bottle - capping machines. AKTIEBOLAGET ALKA ALUMINIUMKAPSLAR. April 26, 1946, No. 12712. Convention date, May 3, 1945. [Class 125(ii)] [Also in Group XXII] In a bottle-capping machine comprising a cap punch and die for forming caps from a blank strip the bottles 1, Fig. 2, to be capped are fed by a star-wheel 2 to the capping head, and the cap punch 22, Fig. 1, is reciprocated, and blank strip feed rollers 35 are intermittently rotated, by the mair drive of the machine. The machine is characterised in that in the absence of a bottle passing the star-wheel, the cap punch 22 and its co-operating die 23 reciprocate as a unit and the rollers 35 are disconnected from the main drive When a bottle to be capped passes the star-wheel, a feeler 3 is depressed so actuating mechanisms which lock the die and connect the strip feed rollers 35 to the mair drive to allow a cap to be punched The depressed feeler 3 depresses a cam 5 so rotating through links 6 and 7 a shaft 8. Rotation of the shaft 8 causes movement of a member 11, Fig. 3. The mechanism rotating the rollers 35 comprises a ratchet 15 and pawl 16, the pawl being prevented from co-acting with the ratchet by a split ring element 14 which is rotated by movement of the member 11 so that a gap in the ring comes beneath the pawl to allow it to co-operate with the ratchet and so intermittently driving the strip feed rollers 35. Within the member 11 is cut a helical cam surface 11a, Fig. 1, with which co-operates a pin 11b upon a slide 12. Rotation of the member 11 causes the slide to move to the right in Fig. 1, so that a member 12a thereupon engages and locks a sleeve 27 incorporating the die 23. The blank strip 29 is fed through a slit 25 in the sleeve, and the die 23 is provided with a cutting edge 26. The downward stroke of the punch will cut a cap blank and force it upon a cap forming tool 28. The formed cap is moved by compressed air through a channel 31 to the capping head. In the absence of a bottle, the feeler 3 is not depressed, the cam 5 is spring-urged to its upper position causing return movement of the member 11 which unlocks the sleeve 27 which will reciprocate as a unit with the punch 22 by virtue of the frictional contact between them, and the ring element 14 is returned so that the pawl 16 will ride upon it to prevent co-operation with the ratchet so interrupting the feed of blank strip. A depressed feeler 3 is returned to its former condition by a cam 4. The machine may also comprise mechanisms for inserting sealing discs in the bottle caps, or for making flutes or corrugations in the tearing off tabs or caps, which may also be driven from the main drive of the machine and operated in a similar manner to that described above.

A rotatable shaft sealing arrangement, particularly for steam turbines, comprises a ring formed of abutting carbon segments 4 mounted and retained in a groove 5 in the shaft housing 2 and urged radially inwards by springs 7 to co-operate with labyrinth fins 3 provided on the shaft, rotation of the segments being prevented by stop means, such as a screw 8, located within the groove. The carbon segments and the groove 5 are of T-section so that the carbon ring is retained in the groove substantially concentric with the shaft 1 by cooperation with rims 6 of the groove. Each segment 4 is urged inwardly by a leaf-spring 7 located between it and the bottom of the groove. The labyrinth fins 3 may be of uniform diameter, as shown, or stepped, the inner periphery of the segments 4 being correspondingly shaped. Instead of being T-section, the segments 4 and groove 5 may taper inwardly as a dovetail.

Abstract: 918,789. Regulating. CITROEN S. A., ANDRE. April 13, 1960 [June 23, 1959], No. 13152/60. Class 7(6) [Also in Group XXIX] Fuel from a pump is supplied to the distributer of an engine via valve apparatus Fig. 1, comprising an inlet port 3, a filter 4, a passage 5, a chamber 2, a passage 5, a chamber 2, a passage 6, an orifice 8, a chamber 7 and an outlet port 9 in a body 1. The amount of fuel is determined by a metering valve 11, 12, Figs. 2 and 4 which controls the by-pass leakage of fuel from the chamber 2 to a return line. The rotary cylindrical member 12 has a blind hole 13 from which radial ports 14 extend to co-operate with radial ports 15 in the sleeve member 11, the ports 15 being interconnected by annular duct 16. The member 12 is also reciprocable within the sleeve 11 and is loaded by a spring 29 in a direction to bring the ports 14 and 15 out of alignment but is normally retained, i.e. when the engine is operating, against an adjustable stop 32 by the pressure within the chamber 2. This reciprocation of the valve member 12 on starting and stopping of the engine produces a scraping action which prevents sticking. One end of the member 12 carries an arm 21 which is connected by a rod 22 to a piston 23 subjected on opposite sides to the pressure upstream and downstream of the orifice 8. The other end of the member 12 is connected to a lever 26 connected to a control member responsive to the vacuum produced by the flow of air to the engine.
