Abstract: 796,270. Dry shavers. SCHICK, Inc. Nov. 8, 1956 [June 28, 1956], No. 34184/56. Class 131 A cutting head for an electric dry shaver comprises a spring yoke having a base and upstanding terminal arms, an outer stationary cutter overlying, and an inner reciprocated cutter between, the arms and means, released by outward or inward flexure, respectively, of the arms, for retaining the cutters relatively to the yoke. As shown, the outer and inner cutters 1, 3 have cooperating toothed flanges 34, 20 and telescoping central channels. A filler block 2 is secured to the base 21 of the inner cutter 3 which has an aperture 43 receiving the drive shaft 14 and projections 22 engaged by compression springs 5 secured to a spring yoke 4 to which the inner cutter is assembled by engagement of the ends of the channel beneath shoulders 18, pressed out from the arms 11 of the yoke, by release of the arms after outward flexure to receive the cutter. The channel of the outer cutter 1 overlies the arms 11 and is provided with bayonet slots 32 in which the arms are engaged after inward flexure, end portions 33 being retained beneath shoulders 17 of the arms 11 on release. Application of the outer cutter to the assembled inner cutter and yoke, compresses springs 5, urging the portions 33 into contact with the shoulders 17 whereas the offset of the shoulders 18 provides a space 36 in which the base of the inner cutter moves without frictional contact. Openings 16 in the arms formed by pressing up the shoulders 17, 18 receive latch members 55 of a retaining spring 6 looped around posts 51 on the motor casing 50.

Title: Improvements in or relating to pressure sensitive adhesives
Inventor: AUBREY DEREK WILFRED
IPC: C09J7/38
Filed: 1959-10-09
Abstract: A pressure-sensitive adhesive comprising a vinyl-addition elastomeric polymer, or tape or sheets coated therewith, is irradiated with electromagnetic radiation with a wave-length between 2,000 and 3,000 . to increase the molecular weight of the polymer.  Specified polymers are natural rubber, a styrene butadiene or acrylonitrile-butadiene copolymer, an isobutylene polymer of copolymer, a low molecular weight polyvinyl ester, and a low molecular weight polyacrylic or polymethacrylic ester.  The adhesive may be irradiated whilst on a backing which is not to be removed before the use of the adhesive.  Access of oxygen to the p  adhesive is restricted during the irradiation, e.g. by displacing air around the adhesive with an inert gas, or by laminating a film, which is transparent or partially transparent to the radiation, on to the adhesive.  An activator may be present during the irradiation, e.g. dispersed or dissolved in the adhesive solution or emulsion, applied to a filler, e.g. polyethylene, dispersed in the adhesive or applied to a surface in contact the adhesive or applied to a surface in contact with the adhesive. Specified activators are benzaldehyde, p-chlorobenzaldehyde, benzophenone and 4-chlorobenzophenone.  In examples, adhesive compositions comprise (1) pale crepe rubber, ester gum, benzophenone and toluene, (2) styrene-butadiene copolymer, hydrogenated ester gum or hydrogenated rosin, petroleum jelly, 2-chlorobenzophenone and toluene, (3) a vinyl acetate-2 ethyl hexyl acrylate copolymer solution containing parachlorobenzaldehyde, (4) a butyl rubber, mineral oil and n-hexane, (5) polyvinyl ethyl ethers (a mixture of low and high molecular weights), benzaldehyde and petroleum ether and (6) polybutyl acrylate, hydrogenated ester gum or hydrogenated rosin, parachlorobenzaldehyde and toluene.

Abstract: 786,772. Storage tubes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 9, 1954 [Dec. 11, 1953], No. 34647/53. Class 39(1). The screen of an electrostatic information storage system comprises areas of insulating material separated by conducting members electrically connected together to form a mesh and a pick-up electrode capacitively coupled to the areas of insulating material and insulated from the mesh and with its conducting elements out of register with the conducting members of the mesh. The mesh may be a number of parallel conducting strips 25, Fig. 3, formed on the insulating material 16, e.g., mica and connected together at one end by a conductor ; or it may be two perpendicular sets of parallel conducting strips 25, 27, Fig. 7. In each case the mesh conductors are applied by the evaporation of a suitable metal, e.g., silver, through a wire mesh, or by a printed circuit technique. The pick-up electrode is either a plate or a discontinuous conductor, e.g., a series of parallel conducting bars opposite the spaces between the bars of the mesh. An alternative form of storage member, Fig. 9, comprises insulated and uninsulated wires 32, 33 disposed alternately in a plane. The insulating material 36 may be of glass, a suitable plastic or aluminium oxide. When the insulating material is thermoplastic, the cylindrical storage members may be heated and flattened as in Fig. 11 (not shown). In another form the coated and uncoated wires are wound spirally.

The percussive element 15 thus has a longer stroke than the cylinder 9. Preferably air is withdrawn from opposite sides of the head 15 simultaneously. The hammer stem 14 has flutes 22 for the passage of air from the space 18 to clear the bore hole. A hole 23 is provided in the cylinder 11 for the admission of air to compensate for leakage.
