IPC: G03B21/10
Abstract: 684,477. Coin-freed kinematograph apparatus. MALCOLM, G. D., and DWYER, E. ST. C. March 1, 1949 [Feb. 4, 1949], No. 5529/49. Class 97 (i). [Also in Groups XVIII and XXXVIII] A cabinet contains a housing enclosing an electric lamp and a condenser reflector, one of the walls of the housing having an opening for passage therethrough of a ray of light from said lamp to and through an endless rotatable motion picture film, also to and through a rotatable octagonal prism and to and through a projector lens, the said film, prism and lens also being within the cabinet. As shown, when a coin is inserted at 35, an endless-motion picture sound film 5 is fed by rollers 7 from a spool 4 over guide rollers 8 and past a gate 6. Light from a lamp 10 passes through the sound track of the film to a photo-cell 20 feeding an amplifier 21 which drives a loud-speaker 23. The lamp 10 also provides the projection beam which passes from a reflecting condenser 11 through the film and through a synchronously-rotating prism 13 to the projector lens 14. In the form shown the image is projected by mirrors 15, 16, 17 to be viewed through an aperture 3 in the cabinet. The mirror 17 may, however, be omitted and the image projected through an aperture in the rear of the cabinet on to an external screen.

Abstract: 727,586. Automatic exchange systems. LICENTIA PATENT-VERWALTUNGS GES. April 23, 1952 [April 24, 1951], No. 10219/52. Class 40 (4). In a switching centre receiving all operating current from an associated exchange and having a start circuit common to all the subscribers and normally connected over one wire of the junction to battery in the exchange, the setting up of an outgoing connection is initiated by the operation of a relay in the start circuit when earth is applied over the caller's loop to the start circuit. The start relay D is self-holding and releases a normally operated relay A which disconnects the start circuit from and connects the control circuit RW of a relay selector to the wire a of the junction AL1. In the exchange, the release of a normally operated relay A1 brings up relay W (not shown) which connects an impulse generator J to the wire a to operate the relay selector RW. The contacts 2 are actuated when the relay selector connects up the line of the caller T2.

Patent GB-2030915-A (GB)
Title: Controlling the heating of a pipe end during thickening
IPC: B29C57/00
Filed: 1978-10-07
Abstract: The wall of one end section of a plastics pipe is post thickened by heating a predetermined length of the end of the pipe to its state of thermal deformability and thereafter causing the pipe to deform within and substantially fill a longitudinally extending, circumferential cavity (28). At the same time, heat (34), (36) is applied to the inner and outer surfaces of the cavity, extending from the back end (30) of this cavity towards, but stopping short of, its front end (32), thus defining a transition zone (42), which prevents the remaining portion of the pipe from being heated and thus easily distorted during the thickening operation. <IMAGE>

Patent GB-2038015-A (GB)
Title: Splicing and termination of optical fibres
IPC: G02B6/38
Filed: 1978-12-20
Abstract: To make a splice between two plastics (e.g. silicone) clad optical fibres, or a termination for one such fibre, the cladding is removed from the end region of the or each fibre and replaced by a sleeve of a heat- shrinkable fluorinated or perfluorinated carbon polymer or copolymer, which is heated to shrink it on to the fibres or the fibre. The material used for the sleeve is so chosen as to have a light-guiding function for light in the fibres; an exemplified material is polyvinylidene fluoride. In the case of the termination the end is polished back so that the end face of the sleeve is flush with the end face of the fibre end. In both cases an outer protective sheath is subsequently applied.
