Title: Improvements in or relating to television pick-up cathode ray tubes
Inventor: FRANK KURT JOSEF
IPC: H01J29/45
Filed: 1951-07-09
Abstract: 721,948. Television pick-up tubes. ENGLISH ELECTRIC VALVE CO., Ltd. March 17, 1952 [July 9, 1951]. No. 16273/51. Drawings to Specification. Class 39 (1). The target for a television pick-up tube comprises a transparent signal layer 2 covered by a coating of insulating material applied e.g. through a mesh to form insulating squares or areas, and a layer of photo-conductive material which is only in electrical contact with the signal layer at the gaps between the insulating squares or areas. The insulating material may be SiO 2  applied by evaporation in vacuo. Control of the thickness of the photo conductive layer and of the size of the insulating portions enables the effective resistivity and the time-constant of the target to be adjusted and for photo conductive material of otherwise low resistance to be'used. In a modification the insulating layer is continuous with holes therethrough giving electrical contact between the photo conductive layer and the base.

Title: Improvements in a process and apparatus for regenerating water in aquaria
IPC: A01K63/04
Filed: 1925-06-25
Abstract: 236,227. Beth, E. W. June 26, 1924, [Convention date]. Fish tanks and aquaria.-The water in an aquarium is regenerated by injecting air at about 2 atmospheres pressure by a tube 1 into a tube 3. Water is thus drawn into the tube 3 at the bottom and leaves as a jet by an aperture 6. Carbon dioxide and other noxious gases expelled by the compressed air escape at the top of the tube 4. No filter is used in order not to remove infusoria. The Specification as open to inspection under Sect. 91 (3) (a) also describes a modification in which the air-tube 1 enters near the top of the tube 4 and extends downwardly within it, the tube 4 being straight throughout. This subjectmatter does not appear in the Specification as accepted.

Abstract: 317,163. Hal1oy, A. d'. June 6, 1928. Addition to 285,027. Locking nuts.-The grooved nut of the lock nut device of the parent Specification is replaced by a base ring 5 bored to a larger diameter than a thin sleeve portion 4 of the nut 3 with which it cooperates to form the groove 6 which receives the suitably sectioned split - spring locking ring 7. The locking ring 7 may be arranged axially between the nut 3 and the base ring 5. In a modification, Fig. 5, the base ring 5 is dispensed with and the hole receiving the bolt is countersunk at 9 to co-operate, with the locking ring 7. The locking ring is resilient, in both radial and axial directions. Slits or holes in the sleeve 4 give it resiliency.

Compound roofing-tiles. - Roofing shingles and tiles consist of a base 30 of non-metallic water-resistant material having the lower portion and edge thereof covered by a thin metallic shell 31 which has its central part 32 raised above the surface of the base to provide a space for a filling. The base may be of roofing felt, asbestos or granulated cork held together by a binder, mineral wool, infusorial earth or saw-dust impregnated with asphalt or asbestos-cement, and the shell may be of copper. The filling may be of asphalt or bitumen &c. used either alone or with granulated or fibrous materials, or it may be of cement and asbestos. The lower and side. edges of the shell are inclined as at 37, Fig. 2, and they may end flush with the corresponding edge of the base or be bent around the base, as at 35, Fig. 25. One edge of the shell extends beyond the corresponding edge of the base in the form of a tab 36 which is arranged to lie in the plane of the underside of the base and is cut away at its lower edge at 37, as in Fig. 1. The portion 33 of the shell which lies flat on the' surface of the base extends beyond the normally exposed margin of the element a sufficient distance to produce a good joint and for nailing. The flat part of the shell may be cut away, as in Fig. 1, to conserve metal. The base may be of uniform thickness throughout or its lower portion may be of increased thickness. In the case of shingles, the base has cut-outs 47 formed in its lower portion, as in Fig. 10, and the shell is provided with depressed portions 52 which enter the cut-outs 47.
