Title: Improvements in propel and repel pencils
IPC: B43K21/12
Filed: 1932-07-05
Abstract: 401,422. Pencil holders. BOWLER & CO., Ltd., A. T. and BOWLER, A. T., Bond Street, Denton, Lancashire. July 5, 1932, No. 18941. [Class 146 (iii).] In screw-propelling pencil holders having means for preventing overwinding of the mechanism, the longitudinally-movable part of the mechanism, consisting of the lead-carrier and push-rod, is actuated by a single projection on the push-rod, a spring surrounding the rod, and a second spring supported by a plug closing a guide-tube for the movable part of the mechanism serving to cause the projection to re-engage with the operating parts. The lead is carried in a tube bl connected to a larger tube b which is slotted to permit the passage of a projection c<1> on the pusher a, the ends of the slot being closed to prevent disconnection of the carrier and pusher. The pusher is normally retained in retracted position relative to the carrier by a spring d. The projection c<1> passes through a longitudinal slot in a tube e, which is secured to the point section a<1> rotatable relative to the barrel a, into engagement with the convolutions of a spiral secured or formed in a tube g fixed in the barrel. The front end of the tube e is closed by a ring b<x> forming a stop for the shoulder on the lead carrier, so that, on feeding the lead forward, the pusher can move relative to the carrier to eject the stump of lead. Further forward movement of the pusher causes the projection c' to leave the spiral against the action of the spring, which causes re-engagement when the movement is reversed. When the pusher and carrier reach the rear end of the spiral, the projection c<1> is again disengaged, and the part b of the carrier engages a spring f secured in the end of the tube e. Specification 368,660 is referred to.

Title: Improvements relating to the Preparation of Photoconductive Recording Materials
Inventor: VERHILLE KAREL EUGEEN
IPC: G03G5/087
Filed: 1967-04-26
Abstract: 1,199,061. Photoconductive composition. GEVAERT-AGFA N.V. 1 April, 1968 [26 April, 1967], No. 19186/67. Heading H1K A photo-conductive recording layer comprises an inorganic photoconductor dispersed in a binder consisting of a mixture of binding agents which are not mutually soluble in the solid state wherein at least one agent is a polymer containing groups having the properties of a Lewis base and wherein at least another agent is a polymer containing gronps having the properties of a Lewis acid or a neutralized Lewis base or acid and wherein the layer has a porous structure. The cavities of the porous structure are not more than 50% of the volume of the layer, randomly distributed, microscopic and interconnected. The photoconductor may be ZnO and the layer is preferably coated on glassine paper to form an electrophotographic plate. In the specific embodiments the Lewis base polymer is polyvinylbutyral, a cellulose ether derivative, ethyl cellulose or copolyvinyl chloride-vinyl acetatemaleic anhydride whilst the other polymer is copolyvinyl acetate-vinyl laurate, but many other polymers of both types are specified. Acid butyl phosphate, tetrachlorophthalic anhydride and various sensitizing dyestuffs may be added. The recording layer is made by dispersing the photoconductor in a solution containing at least one organic solvent having dissolved therein at least polymers, coating the solution on a support and drying the coating at such a rate that at least a part of one of the polymers precipitates from the solvent before the other polymers and that on completion of drying, the dried coating contains randomly interconnected microscopic cavities. The polymers must not be soluble in water at pH 7, must be differentially soluble in the solvent, must form a clear solution and must be mutually insoluble in the solid state, thus giving a layer which has macroscopic heterogeneities that are detectable by the eye. It is preferred to use a mixture of sym.-dichloroethane, ethanol and cyclohexanone or ethyl methyl ketone, and to dry the coating in two stages, the first at a slow evaporation rate and the second at a much faster evaporation rate.

Abstract: 238,537. Junkers, H. Aug. 15, 1924, [Convention date]. Rods and bars.- An apparatus for upsetting metal sheets and plates, particularly in the form of narrow strips, consists of two pairs of jaws, each pair of which is closed independently so as to grip the plate, and the pairs being movable towards one another so as to upset the plate the jaws on each side of the work being provided with interlocking toothed extensions so that alterations in length and edgewise curvature are effected without wrinkling. Two pairs of jaws 1, 2 and 4, 5 are first closed to grip the plate and are then moved rectilinearly towards each other to upset the plate. Interengaging prongs 9, 10 are provided to prevent the plate from shifting and forming wrinkles, the surfaces of the prongs being slightly below the faces of the jaws so as to allow room for thickening during upsetting. In order to bend an angle iron by forming sector-like upsettings 14 on one of the fianges, the jaws are in the form of sectors arranged in a housing 13, Fig. 2. One pair of jaws 12 are rotatably mounted in the housing to effect the upsetting. The angle iron is arranged with its vertical flange passing through the centre of the cylinder. The upper jaws may be axially fixed to engage a capping pin 19 in a housing 16, Fig. 4, and the lower jaws may be raised by a treadle 22. The rotatable jaws are operated by a hand lever 23 on the lower jaw having a pin 24 passing through an eye in a lever 25 connected to the upper jaw. A single treadle may be used to perform both operations through an eccentric which first effects the clamping and has a projection for engaging the upsetting means. The parts are returned by springs. The foot and hand lever arrangements may be replaced by mechanical operating means. The Specification as open to inspection under Sect. 91 (3) (a) states that the plates &c. may be used for aircraft and similar light constructions. This subject-matter does not appear in the Specification as accepted.
