Title: Deflection start-up control circuit especially for television receivers
IPC: H04N3/16
Filed: 1973-09-12
Abstract: 1469517 Thyristor deflection circuits for TV receivers RCA CORPORATION 30 Aug 1974 [12 Sept 1973] 42812/73 Heading H3T [Also in Division H2] In a deflection circuit for a cathode-ray tube in a TV receiver, a sawtooth current is produced in deflection windings 70 and in transformer 60 from a D.C. supply at 95 under control of switching devices 41, 51, the voltage across a winding 60d, coupled to transformer 60, is rectified by means of a thyristor 104 and is arranged to charge a capacitor 92 so as to boost the D.C. voltage. The boosted voltage is controlled by regulating the conduction angle of thyristor 104 by means of a control voltage derived by rectification of the voltage across a winding of transformer 60. To prevent commutation failure of the deflection stage, a delay is introduced in the regulation of the boosted voltage provided by thyristor rectifier 104. As described, thyristors 41 and 51 together with transformers 60 and 80 provide line deflection and high voltage generating circuits as described in Specification 1,260,375. The A.C. supply is fed via an on-off switch 99 and a circuit breaker 98 to a rectifier 94, the output of which is supplied via a diode 90 to the transformer 60. The transformer 150 provides a supply to the CRT heater 23 and rectifier 160 provides a starting supply for the horizontal oscillator 16. Thyristor 104 rectifies the output across secondary 60d and charges capacitor 92 with a boosted supply. The flyback pulse across secondary winding 60d is clipped by Zener diode 105 and generates a sawtooth waveform across capacitor 109. The boosted supply across capacitor 92 is compared with a Zener diode 118 and controls the conduction of transistors 112 and 113 so as to vary the conduction angle of thyristor 104 to tend to maintain constant boosted voltage. This action is inhibited when first switching on until capacitor 134 has charged via resistors 140, 136 sufficiently to turn on transistor 130. While operating normally, the horizontal oscillator 16 obtains its supply from diode 146 and Zener diode 145.

The undercoat material may be one which either assists or inhibits release of the pressure transferable material. Specified undercoat materials include silicones, cellulosic resins, vinyl acetate/acrylic copolymers, polytetrafluoroethylene, fluorinated ethylene-fluorinated propylene copolymers, and molybdenum disulphide. The base sheet may be made of paper. The pressure transferable pigmented material may include a wax, petroleum jelly, non-drying oils and synthetic resins, and a pigment e.g. carbon.
Patent GB-430539-A (GB)
Abstract: 430,539. Ticket-issuing machines. ELLER, F., 23, Waltharistrasse, Wannsee, Berlin. May 16, 1934, No. 14766. Convention date, May 16, 1933. [Class 106 (iii)] In machines for cutting-off, printing, and issuing strip tickets in which the ticket is fed between a cylindrical drum with adjustable printing blocks and a cylindrical platen, the printing blocks are mounted in radial guides and are moved into the cylindrical printing surface as required by operating members engaging key-controlled stops as the drum rotates. In the railway ticket printing machine shown in Figs. 1, 2 and 3, the strip 1 is led between rollers 3, 4, through the knife 5, between the printing drum 6 and platen 7, between the date printing rollers 22, 22a and out through the opening 80<1>. The printing drum 6 carries for example, five radially adjustable printing blocks 6<a>, 6b, 6<c>, 6d, 6e, each operated by the appropriate key 12 to bring it outwardly into the printing circle. Depression of any one of the keys switches in the motor 27 which turns the printing drum 6 and platen 7 through one revolution. The key also turns one of the levers 10 mounted side by side on the shaft 16 until its hooked lower end projects into the path of one of the sectors, for instance the sector 8<c>, associated with the corresponding printing block 6<c> as shown in dotted lines. This is effected through the links 11 and levers 14. As the drum rotates, the hook catches the edge of the sector 8<c>, thereby causing it to rotate, together with its cam 53, so that the printing block 6<c> may be moved outwards by springs 52. A spring-controlled lever 15 holds each lever 10 in or out. The lever 10 is ultimately returned as the drum rotates by a roller 21 which engages a heel 19 on the lever. The printing block is also returned by a fixed cam 71 which engages a roller 70 at one end of the sector. The depression of any one of the keys also, through levers 38, 36, 39, closes the switch 40 of the motor 27, which, through worm gearing 28, 29 and ratchet mechanism 31, 26, imparts one rotation to the platen 7 which is geared to the printing drum 6. The engagement and disengagement of the ratchet gearing is controlled by a lever 34 which is released by lever 36 when the switch is closed so that its long arm drops and is raised a little later by a roller 41 engaging the platen. Towards the end of the cycle, roller 32 on ratchet arm 31 engages the curved surface of lever 34 and disengages the ratchet gear. Fingers 57<a> on the platen engage the printed ticket and move it between the dating rollers 22, 22<a> and out through the slot 80<1>. The back of the ticket may be printed with invariable matter by a block on the platen 7. Each of the printing blocks carries a toothed sector 43, which, when moved outwardly with the block, operates its appropriate counting mechanism 59 through a pinion 56 and bevel gear.

Title: Improvements relating to machines for inducing flow of fluid, for example, blowers
IPC: F04D17/04
Filed: 1957-07-02
Abstract: 876,614. Transverse-flow blowers and pumps. FIRTH CLEVELAND Ltd. July 2, 1957 [Dec. 7, 1956], No. 44294/60. Divided out of 876,611. Class 110 (1). In a transverse-flow blower or pump comprising means co-operating with a drum-shaped bladed rotor for guiding the whole throughput twice through the rotor, the guide means comprises one or more guide members facing the rotor and extending the length thereof, the member or members being movable from one position to another whereby a free vortex having its core interpenetrating the rotor blades is shifted to an opposite location for the purpose of reversing the flow, the direction of rotation of the rotor remaining the same. In the transverse-flow blower shown in Fig. 1, auxiliary walls 20, 20<SP>1</SP> are pivotally connected at 18, 18<SP>1</SP> respectively to side walls of the casing, and are formed with arms 21, 21<SP>1</SP> which are interconnected by a tension spring 23 so as to bear against a cam 22. When the cam 22 is in the position shown, wall 20 is flush against the adjacent surface of the casing while wall 20<SP>1</SP> fairs smoothly into a curved surface 13 of the casing. When the impeller 1 is rotated in the direction indicated, the flow is in the direction shown, with flow lines F conforming to a free cylindrical vortex having a core V adjacent a curved surface 131 of the casing. If the cam 22 is turned through 180 degrees, wall 201 is retracted into the flush position and wall 20 moves to a position in which it fairs smoothly into the curved surface 13<SP>1</SP>. The vortex core V now occurs adjacent the curved surface 13, and the flow is reversed without reversal of the direction of rotation of the impeller. By setting the cam to intermediate positions the output of the blower can be varied in either direction of flow, zero output being obtained when the cam is at 90 degrees to the position shown. Fig. 3 shows an embodiment in which casing walls 33, 34 are carried by linkages 36 so that they can be moved parallel to themselves from the full-line positions to the dotted positions whereby the direction of flow is reversed. As in the previous embodiment, the output can be varied by setting the walls 33, 34 to intermediate positions. In transverse-flow machines in which stationary guide members are provided within the impeller, as described in Specification 876,612, the guide members may be angularly movable to reverse the direction of flow.

The five sections 52, 53, 54, 55, 56, preferably of equal diameter, have potentials (above cathode) of the first and last equal to that of the tube screen 14, that of the second 53 and fourth 55 being set equal at some intermediate value and the central section 54 at the lowest level, the potentials preferably falling from each end geometrically, e.g. with a common ratio of 2. The inter-section gaps should be only sufficient to prevent arcing, with edges 58 curled to reduce stress. The section lengths need not be symmetrical; if not symmetrical then in a five section lens the second 53 should be shorter than the fourth 55, being eliminated completely in a four section lens. The diameter should be as large as geometry permits; in a multi-gun tube corresponding sections may be combined in multi-aperture elements. The sections may be further subdivided, with minor potential differences between the subdivisions, so long as the monotonic use of potential in each direction from the lowest voltage electrode is maintained.
