Title: Improvements relating to optical systems for use in sound recording or the like
IPC: G11B7/00
Filed: 1935-04-23
Abstract: 455,857. Optical sound recording and reproducing apparatus. GROVES, W. W., 30, Southampton Buildings, Chancery Lane, London.-(I. G. Farbenindustrie Akt.-Ges.; Frankfort-on-Main, Germany) April 23, 1935, No. 12191. [Class 40 (ii)] [See also Group XX] Relates to optical systems for use in making, copying, or reproducing from sound records on photographic material of considerable thickness of layer, the object of the invention being to avoid distortion of the high frequencies due, to great divergence of the rays within the layer when a lens of wide aperture is used to produce the image of a slit on the photographic material. According to the invention, the angle of the pencil of rays producing the slit image is greater in the plane of the length of the slit (i.e. normal to the direction of travel of the film) than in the plane at right angles thereto (i.e. in the direction of travel). For this purpose, between the imageforming lens A and the film D there may be inserted a diaphragm B having a rectangular aperture, the longer side of which is at right angles to the direction of film travel. The Figures are sectional views at right angles to each other, showing the two dimensions of the aperture in the diaphragm B. In place of the diaphragm, a concave cylindrical lens may be inserted, the longitudinal axis of the lens being parallel to the direction of the length of the slit.

Abstract: 494,424. Indica.ting-devices on motor vehicles. CHAMPION, C. H., and COOMBS, F. E. April 29, 1937, No. 12222. [Class 79 (v)] The approach of a motor vehicle to a kerb is indicated to the driver by a device mounted on the vehicle and adapted to control signalling means by its engagement with the kerb. In the Figure, the device comprises a series of flexible metal contact strips 3, 4 and 5 of progressively diminishing length depending from an end of the vehicle bumper 1. As the vehicle draws in to the kerb, strip 3 is bent inwardly by engage ment with the kerb, and electric circuits are completec successively between strips 3 and 4, and strips 4 and 5 The two circuits may operate separate signalling devices, e.g. the first visual and the second audible; or the second circuit may serve to intensify the first signal. The device may be mounted on a pivoted arm by which it can be brought into operative position only when desired, e.g. in a fog. It may also be mounted on a transverse pivot 9 to enable it to ride over obstructions in the road. In the modified construction shown in Fig. 2 (not shown), the strips 3, 4, and 5 are replaced by concentric flexible tubes operating in the same manner. In Figs. 3 and 4 (not shown), a single pivoted rod is employed, engagement of its lower end with the kerb causing it to swing inwardly, and, through a mechanical or hydraulic connection, displace a contact arm over a series of fixed contacts.

Title: Improvements in and relating to methods and machines for the rapid production of ice
IPC: F25C1/06
Filed: 1956-04-20
Abstract: 802,593. Ice making. WILBUSHEWICH, E. April 20, 1956, No. 12247/56. Class 29 In a method for the rapid production of ice blocks, the blocks are formed from liquid in an upright mould B1 having an inner core 6 and jacket 18 evaporators, heat being supplied to the core and jacket during a defrosting cycle for releasing ice blocks from the moulds, the total available refrigerative capacity during the freezing cycle is so controlled between the core and jacket that a substantially greater proportion thereof is supplied to the core, and the heat used to release the block during the defrosting cycle is so distributed between the core and jacket that an ice-block formed during a freezing cycle is freed from the core and jacket at substantially the same time. Preferably the flow of refrigerant to the jacket is controlled by a striction ring or an adjustable obturator. The refrigerant circuit comprises compressor G, condenser H, receiver i, a vessel D with float valve F, and a liquid separator E. The line 1 from the receiver i is connected through expansion, valves 1a to the core evaporators of a group of moulds B1, the outlets of the core evaporators being connected to a suction line 2 leading to the liquid separator through stop valves 2a. Branch lines 21, before the valves 2a and in each of which is situated a striction ring or adjustable obturator, lead to the jacket evaporator. A line 3 from the liquid separator E has branches leading liquid refrigerant through expansion valves 3a to the bottom of the jacket evaporator. Line 4 leads from the compression line, by-passing the expansion valves 1a, through stop valves 4a to the core evaporators and line 5 leads through stop valves 5a, by-passing the expansion valves 3a, to the vessel D and through float valve F to the liquid separator E. For freezing valves 4a and 5a are closed and for defrosting valves 2a are closed, and valves 3a and 4a opened. In a group of moulds as shown in Fig. 1, preferably each mould consists of a number of freezing cells as in Fig. 2a with individual core evaporators 6 and a common jacket evaporator 18. Each mould is at a different stage of production and excess refrigerant arising from defrosting one of the moulds is redistributed to other moulds from the liquid separator E as necessary. Initial defrosting i.e. after the first filling of a mould with liquid, is started by the longitudinal expansion of ice in the cells forcing down the mould cover K and operating a switch. Thereafter a portion of the ice block remains in the bottom of the mould and the whole process is then controlled as by time switches or by a preset programme. Specification 718,240 is referred to.

Title: Improvements in or relating to electric fusible devices
IPC: H01H85/042
Filed: 1957-04-15
Abstract: 811,962. Fusible cut-outs cable couplings. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 15, 1957 [April 26, 1956], No. 12247/57. Class 38 (1). [Also in Group XXXVII] A current-limiting fuse cornprises a cylindrical insulating casing 1 containing an insulating core 3 with a helically grooved surface and a cylindrical fusible foil 9 located between the core and casing and connected at one end to a terminal cap 2 and at the other end to an apertured vent plug 6. The core 3, or both the core and the casing, may be formed of gas-evolving, arc-quenching material. Fig. 2 shows a modification in which a further fuse element 13 which operates on low overload is connected in series with the foil 9 and located in a tube 14 forming an extension of the casing 1. This type of fuse may be used in a tapping connector as shown in Fig. 4. The terminal cap 2 is coupled to a line-clamp 20 and a tapping cable 23 connected to a conductor 19 secured to element 13. Ejection of the conductor 19 on rupture of element 13 gives an indication that the fuse has blown or alternatively a compression spring arranged to separate the element 13 may project an indicator below the bottom of the tube 14. The basic fuse shown in Fig. 1 may be used in cut-outs as shown in Figs. 5 and 7. In Fig. 5 the vent plug has an apertured extension 6a for attachment of the fuse to a terminal 27 and the terminal cap 2a is formed with a terminal 30 which is also used for the attachment of a porcelain housing 29. In Fig. 7 the upper terminal cap 47 is adapted for attachment to an insulating handle 45 by means of which the fuse may be inserted in or withdrawn from an insulator 49 in which are supported coaxial contacts 48, 51, the lower end of the fuse having in this case a cap contact 52 for engagement with contact 51. Other applications of the fuse shown in Fig. 2 are in outdoor types of cut-out (Figs. 6 and 8, not shown), wherein the lower end of the fuse is connected to a pivot through a toggle held set by the conductor 19. On rupture of element 13, the toggle collapses and allows either the door of the casing which carries the fuse in one application, or the fuse itself, to swing down, at the same time disconnecting the fuse from fixed contacts. A handle on the door or on the fuse permits manual operation if desired.
