A character display panel consists in an array of spaced gas-filling cavities 22, Fig. 2, arranged in spaced parallel planes, conductors 14, 26 at opposite ends of the cavities and fluorescent material 28 exposed to the gas in each cavity; potentials applied to apporpriate pairs of the conductors cause the cavity at the crossing point to glow and to excite the fluorescent material which is visible through transparent end-plate 25. As shown, the cavities are provided in an insulating block 16 and may be tapered away from plate 25. The other end-plate 11 may be metal (Al) with an insulating layer 12; or insulation (BeO, Al 2 O 3 ).

The filling is mercury and argon and is introduced through orifice 29 and distributed by recessed area 19, or by separate channels, Fig. 5 (not shown). The switching of potentials to appropriate conductors may be done by individual switches 35, 38 or by a cathode-ray beam 62, Fig. 4, scanning over individual cathode electrodes 52 projecting into each cavity. In the latter form the discharges, once initiated, are maintained by voltages applied between electrodes 53, 54 and can be erased by switch 56. Colour display can be provided in either the lamp or cathoderay form by providing groups of three cavities exciting differently coloured phosphors and controlled, in the lamp form, by separate ones of triads of conductors, Fig. 7 (not shown). A lens may be incorporated in the front of each group of cavities.

Abstract: 1,236,415. Reciprocating conveyers; shoots. INTERNATIONAL BUSINESS MACHINES CORP. 3 July, 1968 [14 July, 1967], No. 31751/68. Headings B8A and B8S. Carriers of electronic modules are attached to a conveyer chain for passage through a tinning apparatus (not shown) and are then loaded on to the apparatus according to the invention, wherein the electronic modules are removed from the carriers. The carriers 4, which comprise a base 8 with protruding arms 9 mounting pairs of spring clips 10 between which the modules 11 are gripped in two parallel rows, are manually loaded on to a carrier support 5 and locked in position by spring-biased hooks 27. The support 5 is pivotally mounted at 13 to a framework 19. Also mounted on said framework, but for a sliding movement, is a carriage 49 with a plurality of protruding fingers 62 pivotally mounted thereon at 34. In operation, a handle 26 is manually displaced causing a cam 24, attached thereto to move a cam follower 55 which through linkages 50-54, 36, 37, 39-42 moves the carriage 49 forward. As the carriage approaches its foremost position a spigot 66 depending from the fingers engages a stop 70 to pivot the fingers from an upper position, Fig. 3 (not shown), to a position disposed over the electronic modules (Fig. 4, not shown). With further movement of the handle 26 a wheel 23, attached to the cam 24, engages the lower surface 22 of the carrier support 5 and pivot the same about 13 and in so doing raises the arms 9 between the fingers 62 and prises the electronic modules from the spring clips 10. The rows of modules fall on to respective stationary surfaces 6a, 6b sloped outwardly to maintain the rows separate and are then moved along said surfaces towards respective shoots 90, 91 by a manually operated pusher 77. The two shoots 90, 91 feed a common shoot 92 by way of a control gate 80. Each shoot 90, 91 has a photo-electric cell 87, 86 and once a shoot is open it will remain so as long as the modules pass through the respective cell. When the flow of modules from one shoot ceases the gate 81 changes to release the modules from the other shoot. Situated below the control gate 80 in the path of the single shoot 92 is a slidable platform 2 with a straight through path and a path containing a turntable 88 to turn the modules through 180 degrees. The movement of the carriage 49, the support 5 and the pusher 77 may be other than manual, e.g. electric or fluid operated.

Abstract: Acrylonitrile is freed from aldehydes and ketones by a process wherein crude acrylonitrile, which has been obtained by aqueous extraction from acrylonitrile-containing gases of reaction, subsequent separation of the crude acrylonitrile from the main portion of water by distilling in a stripper column, and separation from the distillate of the acrylonitrile-containing organic phase, which process comprises, if necessary, enrichment of the crude acrylonitrile with gaseous hydrocyanic acid, addition of an alkaline reaction medium as a catalyst for the formation of cyanohydrins, subsequent acidification with a mineral acid or an organic acid in a quantity at least sufficient for the neutralization of the previously utilized alkali, removal by distillation of substantially all of the water and, simultaneously at least the major portion of the free hydrocyanic acid, preferably returning the head fraction of the last distillation to the purifying process, especially to the cyanhydrin forming steps.

Title: A load sharing clutch arrangement for use with a plurality of synchronous electric motors driving a single rotary output member
IPC: F16D43/286
Filed: 1967-07-12
Abstract: 1,145,136. Controlling clutches. DOMINION ENG. WORKS Ltd. 12 July, 1967 [18 July, 1966], No. 32102/67. Heading F2L. Load sharing between two or more synchronous electric motors 25 driving a single output member 21, such as a grinding mill, through respective air actuated clutches 24 is achieved by limiting the torque transmitted by each clutch to a predetermined maximum during starting. For each motor, a switch 27 sensitive to motor current energizes a solenoid valve 28 controlling compressed air supply to the clutch 24 associated with that motor. In operation, the motors are run up to synchronous speed with the clutches disengaged. The valves 28 are then opened to admit compressed air for clutch engagement. When the starting current of a motor reaches a predetermined value, e.g. 150% of full load current, the respective switch 27 operates to close its valve 28 to hold the torque transmitted by that motor at a predetermined level. This will occur on all clutches before full speed is reached, so that at full speed the motors will be in balance. The full air pressure is then applied to the clutches. Motors of different capacities can be used together by suitable arrangement of the control values.
