Abstract: 1,231,940. Chargeless electro-photographic processes. RICOH K. K. May 29, 1969 [June 7, 1968], No.27267/69. Heading G2H. A chargeless electro-photographic process comprises firstly determining the boundary exposure Em, of the photo-conductive copy material for a given developer by plotting amount of exposure against density of developed image: Em being defined as the exposure required for maximum image density with the given developer. Exposures greater than Em produce images of the opposite polarity to those formed by exposures below Em and thus, for a given developer, both positives and negatives of an original can be made by exposing to the appropriate quantity of light (visible ultraviolet or infrared) and developing. The developer may comprise a kneaded mixture of a pigment, e. g. carbon black, with an alkyd resin (or octadecylmethacrylate-vinyl diethylaminoethyl ether copolymer, or vinyldodecyl etherdibutylaminoethyl methacrylate copolymer, or dodecyl methacrylate-styrene-diethylaminoethyl methacrylate copolymer), dispersed in a petroleum hydrocarbon carrier or the developer may comprise pigment, an alkyd resin, (or octadecylmethacrylate-vinyl diethylaminoethyl copolymer, or dodecyl methacrylate-styrene-diethylaminoethyl methacrylate copolymer) and a metal salt of a fatty acid (e.g. manganese napthenate, cobalt napthenate, calcium napthenate, zinc stearate), dispersed in a petroleum hydrocarbon carrier.

Abstract: 1,232,114. Laminates. WESTERN ELECTRIC CO. Inc. 22 May, 1968 [29 May, 1967], No. 24449/68. Heading B5N. [Also in Division H2]  A method of sheathing an elongated article 10 comprises conveying the article along a conveying means in an upstanding position relative to the conveying means, covering the article with a plastics sleeve 12 shrinkable by heat into intimate contact therewith, and applying heat progressively up the sheathed article so as to shrink successive portions of the sleeve into intimate contact with the article without entrapment of air. As described, metal wire connectors 10, in the form of tubes closed at one end, are fed at a station 26 on to pins 16 secured to a belt 20. A sleeve 12 cut from tubing 12-1 of heat-shrinkable, dielectric material, e.g. polyolefin, is telescoped over each connector 10 and the assembly so formed is moved past a narrow heating zone 32 obliquely disposed relative to the conveyer so that the sleeve is heated progressively from one end to the other. The heat may be provided from quartz lamps, and focused into the zone 32 by elliptical reflectors. After heating the sheathed connectors are stripped from the belt 20 by wedges 38.

Abstract: 1,234,518. Turbine blades. GENERAL MOTORS CORP. May 2, 1969, [May 22, 1968], No.22488/69. Heading F1T. Gas turbine nozzle guide blades 5 are welded, at least at one end, to a hollow box-section shroud or platform structure 8, the weld being within the respective shroud or platform so as to be shielded from the hot gas flowing past the blades 5. Each of the latter is hollow and has a laminated porous wall including an outer layer 16 of a dispersionstrengthened nickel-chromium alloy containing thoria, and intermediate and inner layers 17, 18 of unstrengthened alloys. A sheet metal baffle 19 guides cooling air within the blade 5. In the embodiment shown there are individual shroud segments at both ends of each blade 5, the radially inner segment having a peripheral flange 23 to which is welded a porous facing 25 to define the box section. The facing 25 has an aerofoil shaped opening through which the blade end extends, the latter being welded at 33 to a flange 30 surrounding the opening and welded to the facing 25. The zone of the blade weakened by the attachment weld 33 is thus shielded from the hot gas flowing past the blade. The latter is welded to the radially outer shroud segment in the same manner. The cooling air is supplied to the interior of the inner shroud segment through a hollow mounting boss 37 and part flows to the chamber defined between baffle 19 and the concave flank 13 of the blade, some then flowing through the baffle 19 to the remainder of the blade interior before exhausting through the porous blade wall into the gas stream. Plugs 40, 41 close the ends of this remaining part of the blade interior. Some cooling air also flows to the outer shroud segment and exhausts through porous facing 24, inner facing 25 being similarly cooled. In modifications, the hollow shrouds or platforms can be annular rather than segmental and may be provided at only one end of the blade.

Abstract: 1,257,078. Shock absorbing bumper. H. GRANIG. 5 Feb., 1969 [5 Feb., 1968], No. 6255/69. Heading B7J. [Also in Division F2] A bumper bar 2 is connected to a vehicle by telescopic cylinders 1 which are extended on actuation of a switch by an occupant immediately prior to a collision by means of compressed gas from a cartridge in a source 20, the telescoping of the cylinders 1 on impact being controlled by a vent 103 and a further supply of gas, so that they act as shock absorbers, lessening the risk of vehicle damage and occupant injury. As the cylinders telescope, slack in a cable 16 attached to the bumper bar 2 will be taken up by a vehicle mounted spring-biased drum 22, Figs. 2, 3, which on rotation moves a finger 26 on a pin 29 from a groove 24 via a helical groove 25 to a groove 24<SP>1</SP>, the pin 29 thus pivoting a bell-crank lever 30 to move an actuator 31 which releases firing pins (57), Fig. 5 (not shown), which fire a number of cartridges, the number being controlled in dependence on the vehicle velocity, to provide the further gas supply. The vent 103 is actuated by a lostmotion means 107, 108, Fig. 8, linked to the bell crank 38 by members 105, 40 and 40<SP>1</SP>. The size of the vent 103 is controlled by the amount of lost-motion, which is varied by rotating the member 105, by means of a shaft 104 linked to the vehicle speedometer. The bumper bar 2  may be retracted by the vehicle engine which is coupled to the drum 22 by means of a gear rim 23, a pinion 49, a shaft 50 and a coupling arm 35 engageable with a V-belt pulley, Figs. 2, 3. The drum 22 is disengaged from the engine when the bumper bar 2 is completely retracted, by a stop 47 on the cable 16 acting through a linkage 44, 46, 43, Fig. 3, to retract the shaft 50 against the force of a spring 42. The bumper bar 2 is pivotally connected to the cylinders 1 with some lateral freedom to accommodate an oblique impact.
