Abstract: 305,319. Eller, F. Dec. 1, 1927. Ticket printing and like apparatus; delivery of tickets cut from strips.-In an apparatus for printing and delivering tickets comprising a rotary shaft and means for coupling it to the ticket printing and delivering mechanism, an electromagnet and coin-freed mechanism controlling the same are provided for actuating the coupling means. The invention is described as applied to the ticket printing and delivering mechanism and coupling mechanism described in Specification 242,810, [Class 106 (iii), Fares &c.]. The ticken printing and feeding rolls 60 - - 63, Figs. 1 and 3, are driven by a wheel 53 meshing with a wheel 20 fixed to a cam disc 15 which is coupled, after prepayment, for one revolution by a pawl 23 to a toothed member 14 on a rotary shaft 7 driven by an electromotor 3. A knife 49 for cutting off the ticket from a strip 65, allowing it to pass by a shoot 67 to a delivering tray, is actuated from a groove 19 in the cam. The pawl 23 is pivoted at 22 to the disc 15 and is normally held out of engagement with the member 14 against a stop 31 by the nose 27 of a member 28 which is pivoted at 30 and pressed to releasing position by a spring 34. The member 28 is held in engagement. with the pawl 23 by a shouldered arm 37 on a shaft 38 which is provided with an arm 39 carrying a pawl 40. After prepayment, an electromagnet 71, Fig. 1, is energized and its armature is connected to a rod 72 carrying lugs 85, 86. In the upward movement of the rod, the lug 85 moves a lever 77 to press contacts 76 thereon against spring contacts 75 thereby closing the circuit of the motor 3. A roll 78 on the lever 77 is disengaged from a notch in a disc 80 mounted on the shaft of the printing roll 62, and rides on the periphery of the disc thereby keeping the contacts 75, 76 closed for one resolution of the shaft 7. The lug 86 meets the pawl 40 and actuates the shaft 38 to release the member 28 thereby allowing the pawl 23 to engage the member 14 under the action of a spring 25. The member 28 is returned by a roll 32 thereon engaging the periphery of the cam 15.

Spherical nuclear fuel particles are produced by mixing a minor proportion of magnetic non-active particles with a major proportion of active core particles, and coating the mixed particles first with carbon and then with a sealing layer. Particles of carbide or oxide of U, Pu or Th are mixed with magnetic cermet particles containing iron with or without Ni, Co, Mo, V or W. A fluidized bed process may be used for coating the particles with pyrolytic carbon and then with silicon carbide or zirconium carbide. The coated particles are subjected to gas under pressure and then sudden decompression in order to open the coating on imperfectly coated particles. The particles are then allowed to travel down a vibrating inclined table so as to separate the broken from the unbroken particles. For testing the quality of the coatings, the magnetic particles are separated from fissile particles and examined as representative of all the particles in respect of the coating.

Title: Improvements in advertising, display, and signalling apparatus
IPC: G09F11/29
Filed: 1934-11-16
Abstract: 441,572. Moving signs. CARNEGIE, D., The Haven, Seasalter, Whitstable. Nov. 16, 1934, No. 32971. [Class 3 (i)] A non-endless band forming a colour filter is automatically wound on and off two rollers 2, 3. A continuously driving motor 5 rotates a shaft 12 through belt and worm-wheel gearing, and on the shaft 12 is carried a frame 13 furnished with two trains of gear wheels 14, 15, 16 and 17, 18 each meshing with a wheel 19 on the shaft 12. The drive is effected through one or the other of these two trains according to the position of the frame 13, the terminal wheel 16 or 18 engaging one of two pinions 25 on the shaft 20 of the roller 2. The frame 13 is swung from one position to another by a spring toggle 40, 36 pivoted to the casing at 37. A pin 39 on the element 36 bears against the toggle spring 44 when the element 36 is raised by an abutment 32 on a cam 31 striking a roller 35 on the element 36, thus snapping up a pin 42 on the extreme end of the element 40. The pin 42 works in a slot 43 in the frame 13, and its upward movement puts the wheel 16 into mesh with its pinion 25. The downward movement of the pin 42 is effected by abutment of the cam rise 33 against a tail 41 on the element 40, and brings the wheel 18 into mesh with its pinion 25, thus reversing the drive. The wheel 16 drives the roller 2 direct, while the wheel 18 drives the roller 3 through the medium of chain and sprocket-wheels 22, 24. The cam 31 is driven through gearing 27, 28, 29 from the shaft 20, and makes an oscillating movement only. The band may be a single multi-coloured strip, or may be formed of coloured panels attached to a strip. The length of each coloured portion will determine the time for which such colour shows. The strips are readily attachable to the rollers 2, 3 for changing purposes, and the rollers are larger in the middle than toward the ends. The device is applicable to advertising, flood and spot lighting, traffic signalling, and signs. A plurality of coloured sheets may be provided, each driven by its own motor, and the element 40 is made to make and break circuits through the driving motors to stop all which have their sheets in advance till the hindmost sheet catches up, when all the motors are re-started.

The apparatus has four arms 2A, 2B, 2C and 2D carried by hollow shaft 4 and each arm carries cups 10. The drive from chain 24 passes from shaft 23 via bevel gearing 22 to shaft 21 and thus drives cam 25 and 32 and step-by-step Geneva mechanism 18, 19, 20. Cam 25 causes up-and-down movement of shaft 4 via linkage 26, 27, 28, and Geneva mechanism 18, 19, 20 causes step-by-step rotation of the same shaft 4. Cam 32 causes operation of valves 15 of the cups 10 via linkage 34, 37, shaft 38, cam 39, and linkage 42, 43, and operating bar 44. Operation.-Arm 2B descends so that cups 10 fit over a row of eggs in tray 8. At this moment bar 44 descends to operate valves 15 to allow air to escape from the respective cups. The eggs are then held by suction in the respective cups. The apparatus then rotates step-by-step till arm 2B is positioned over discharge conveyer 6. The arm 2B then descends and at the same time bar 44 descends to operate valves 15 to cause the cups 10 to release the respective eggs. The eggs fall on to arms 45 which pivot to push the row of eggs on to conveyer 6. The other arms 2B, 2C, 2B act similarly. Second embodiment.-The cups 10 are supplied with artificially-created suction so that the eggs are both held and released under positive air pressure from a vacuum pump.

Title: Switching arrangements
IPC: H04N5/268
Filed: 1961-09-15
Abstract: 986,930. Transistor switching circuits. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Sept. 15, 1961 [Sept. 15, 1960], No. 33186/61. Heading H3T. In a switching arrangement for connecting one of a number of channels to a common output, change from one channel to another is effected by bistable control circuits, the state of the control circuits being switched only during the coincidence of a switching pulse signal and a voltage signal from a channel selector. One of a number of video channels I, II, III, Fig. 1, may be selectively connected to a common output T by forwardly biasing the appropriate one of the diodes 2, 2<SP>1</SP>, 211 with a positive signal and reverse biasing the other two with negative signals. The control circuit comprises bi-stable circuits 9, 9<SP>1</SP>, 911, each consisting of a pair of cross-coupled transistors, Fig. 2 (not shown), having input terminals 8, 10 and an output 15, and AND gates 16, 16<SP>1</SP>, 16<SP>11</SP> which conduct when appropriate potentials are applied to their emitters and bases to deliver switching signals to the inputs 8, 8<SP>1</SP>, 8<SP>11</SP> of the associated bi-stable circuit. Assuming initially channel II is connected to the output T, then the bi-stable circuit 9<SP>1</SP> is producing a positive output at terminal 15<SP>1</SP> and is in the state which responds to an input at 10<SP>1</SP>, diode 221 is forward biased and determines the potential at point 24 such that transistors 16, 16<SP>1</SP>, 16<SP>11</SP> are cut off, diodes 11, 11<SP>1</SP>, 11<SP>11</SP> are cut off, preventing synchronizing pulses 23 from reaching the inputs 10, 10<SP>1</SP>, 10<SP>11</SP>, and bistable circuits 9, 911 are in their other state in which they respond to inputs at 8, 8<SP>11</SP>. If it is required to switch to channel III, switch 1311 is closed forward biasing diodes 11, 11<SP>1</SP>, 11<SP>11</SP> so that the next synchronizing pulse 23 switches the state of the bi-stable circuit 9<SP>1</SP>, thus cutting off diode 2<SP>1</SP>. Diode 22<SP>1</SP> becomes reverse biased, allowing the potential at the point 24 to change to forward bias the bases of transistor 16, 16<SP>1</SP>, 1611, and the positive potential at the emitter of transistor 1611 due to switch 1311 being closed allows this transistor to conduct on the next synchronizing pulse and pass that pulse to the input 8<SP>11</SP>. Bistable circuit 9<SP>11</SP> now switches to its other state and provides a positive output at 15<SP>11</SP> which forward biases diode 211 thus connecting channel III to the output T, and also forward biases diode 2211 to reset the potential at point 24 to cut off transistors 16, 16<SP>1</SP>, 16<SP>11</SP>. In a modification, Fig. 3 (not shown), the control signal paths are connected to the diodes 2, 2<SP>1</SP>, 2<SP>11</SP> via further diodes which are arranged to be conductive when the associated diodes 2, 2<SP>1</SP>, 2<SP>11</SP> are non-conductive to form a by-pass path for the video signals not being fed to output T.
