Abstract: 1430268 Gas discharge display panels FUJITSU Ltd 5 April 1973 [6 April 1972] 16449/73 Heading H1D Dielectric layers 2 and 4 covering crossed electrode arrays mounted on base-plates 1 and 3 of a gas discharge panel have either different thicknesses or different dielectric constants such that wall charges produced by discharges between adjacent electrodes of an array are larger than those produced by discharges between opposite electrodes of the two arrays. Electrodes a 1 , b 1 , c 1 , d 1 , a 2  ... are connected to a four-phase supply so that application of a pulse to a start electrode W causes a surface discharge initiated by a priming discharge maintained continuously between keep-alive electrodes K1 and K2 to step along the array. Application of a write pulse to a selected electrode y 1  to y 4  with suitable timing (Figs. 5 and 6, not shown) causes a discharge to a selected electrode a 1 , b 1  .... Layer 2 is made either thinner or of a higher dielectric constant than layer 4, and the resulting difference in the wall charges prevents spurious operation due to the commoning of electrodes a 1  and a 2 , b 1  and b 2 , &c.

Title: An improved method of and means for effecting combustion in internal combustion engin
IPC: F02B19/00
Filed: 1931-06-08
Abstract: 384,340. Oil engines. RICARDO, H. R., 21, Suffolk Street, Pall Mall, London. June 8, 1931, No. 16659. [Class 7 (iii).] In a compressionignition engine of the type in which substantially the whole of the air charge is forced into a spherical offset combustion chamber F during the compression stroke, the fuel is discharged by an injector H in a compact stream which passes through the centre of the chamber and impinges on an uncooled plug G, which forms the lower portion of the combustion chamber, at a spot adjacent to a tapering passage G<4> through which the air is forced tangentially into the chamber ; the circumferential portions of the rotating air charge are thus brought progressively into contact with the fuel spray as it impinges on the plug so that the air and fuel are thoroughly mixed immediately before the charge reaches the inner end of the passage G<4>, and the tendency for unconsumed air to be driven out of the chamber is reduced. No fuel is injected directly into the end of the passage. The passage may be of circular cross section throughout, or it may change to a crescent or kidney shape towards its inner end, the area of the latter end being preferably three-fifths that at the outer. Instead of the passage traversing the plug, it may be formed by a groove cut in the outer cylindrical surface of the plug, the direction of rotation of the charge thus being opposite to that obtaining in Fig. 1. The plug G is made of a heat-resisting metal of low heat conductivity ; it is fitted loosely in the mouth of a water-cooled pocket so that it is surrounded by a heat insulating air-space F<1>. A retaining ring G<2> may be optionally provided, the off-set of the plug ensuring sufficient overlap between the cylinder end and plug to retain the latter if the ring is omitted. In the modified construction shown in Fig. 3, the upper portion of the combustion chamber is provided with a liner K which is insulated from the watercooled pocket by an air gap ; the liner is supported by an integral boss K<1> which passes through a bore in the wall of the pocket and is secured by a ring K<2>. An electrically heated hot wire J is employed at starting. The injector socket passes through the water jacket chamber of the cylinder head to ensure adequate cooling. Specification 371,025 is referred to.

Title: Photographic type composition
IPC: B41B21/20
Filed: 1958-05-27
Abstract: 891,142. Selective punching apparatus. HARRIS - INTERTYPE CORPORATION. May 27, 1958 [May 27, 1957], No. 16875/58. Class 31(2). [Also in Groups XX, XXIV and XL (c)] In a photographic type-composing machine (see Group XX) in which the composition is recorded longitudinally on a strip film 135, the content of successive lines is divided by punched holes 272 and the interword spaces are indicated by small perforations 1. As shown, the film strip 135 passes from a supply cassette 143 round jockey roller 146, between shoes 158, 160 of a brake held normally released by energization of a solenoid 170, over roller 177, around flanged roller 200 on carriage 202 and over roller 217 to take up cassette 222. When starting a composing operation after the insertion of a film strip, a solenoid 397 is energized from the keyboard to cause a punch 215 to be operated, through pneumatic piston and cylinder means, to dimple the film and so locate it and a solenoid 310 is de-energized to allow pinion 297 on drive shaft 300 to engage gear 295 driving carriage 202. During composition the carriage is moved to the right (Fig. 1) in accordance with the accumulated widths of the characters and spaces. Interword spaces of two picas are produced by operation of the space bar (Fig. 3, not shown), the spacing mechanism also operating, through a pneumatic servomotor, a punch 120 on a pivoted arm 117<SP>1</SP> to make an interword perforation at the exposure gate 140. As the film is carried to the right by the carriage, jockey roller 146 closes switch 145 to energize the film pay-out motor 144 to maintain sufficient film to allow for the carriage movements. When a complete satisfactory line has been composed, an " end of line " key is pressed, momentarily energizing solenoid 400 so that punch 215 is allowed a further travel to perforate the film and then de-energize solenoid 170 so that the brake shoes 158, 160 engage the film and the switch 175 is opened by the end of the solenoid core under spring action. Thereafter follows de-energizing of both solenoids 397 and 400 to retract the punch from the film, energizing of solenoid 310 to disengage pinion 297 from the carriage driving gear, and energizing of the film winding-up motor 224 which also pulls the carriage to the left until lug 406 on the carriage engages a stop 405 on the gear 295. As the punch is retracted, the film is stripped therefrom by a stripper block 208 while the punchings are carried away to a passage 194. Continued winding-up of the film moves the pivoted brake mounting 150 anticlockwise to close switch 408, releasing the brake shoes, stopping motor 224, de-energizing solenoid 310 and energizing solenoid 397 so that punch 215 dimples the film at the start of a fresh line. If the line composed is unsatisfactory, a " reject " key is operated when the punch 215 is withdrawn without perforating the film and the apparatus goes through the rest of the " endof-line " routine to wind-up the film and return the carriage for composition of a fresh line.
