Title: Improvements in and relating to luminous indicators for supervising technical plants
IPC: H02B15/00
Filed: 1932-09-19
Abstract: 407,715. Electric signalling systems. AKT.-GES., BROWN, BOVERI, ET CIE. Baden, Switzerland. Sept. 19, 1932, No. 26051. Convention date, Sept. 17, 1931. [Class 40 (i).] A mimic diagram for supervising industrial plants performing operations upon or conveying materials is operated by electrical signalling devices which are provided upon parts of the plant which are traversed by or operate upon the material, and which control light signals in the mimic diagram according to the properties of the materials or events in their production. The invention is particularly described with reference to a combined planing and milling machine, a diagrammatic representation of which is painted on a dark metal sheet 1 with luminous paint, and comprises a frame 2, a movable cross beam 3, a bed 4, and planing table 5, with milling-tool holders 6 and planing- tool holders 7. Openings 8-11 are cut in the sheet 1 and covered with glass, and lamps or the like are situated behind the openings and are controlled by switches carried by or associated with the different parts of the machine. When the lamps are not illuminated the image is dark to indicate that the plant is switched off. When switched on, the lamps behind openings 8 in the frame 2 light up, and if the machine is set for milling, the lamps of the milling-cutter openings 9 light up either green or white, while the symbols of the planing-tools 10 are dark. Blocked tool holders are indicated by a green light, and those which are ready for operation by a white light. During the raising or lowering of the beam 3, the green light at the apertures 8 which indicates that the frame is in its normal working position is changed to a mixed colour by lighting also a red light; the green light is extinguished when the beam is completely removed and only the red light shows. Lamps such as 11 which light only in one colour show when so illuminated that the oil pump, for example, is in operation. The image of the machine &c, can be drawn on a glass plate or be made by scraping away the coating of a coated glass plate, which is then illuminated from the back. Changes in the physical condition, e.g. weight, light, permeability and hardness, may control the signalling devices operating the illuminating means. Application to cement plant is outlined.

Abstract: 463,553. Adapting automatic guns for practise fire. LATKA E. VON LATSCHER-, KOZURIK, O. VON, and RZIKOWSKY, F. G. BECK-. Sept. 28, 1935, No. 26877. Convention date, April 24, 1935. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 2, 1936.] [Classes 92 (ii) and 119] Relates to machine guns and automatic pistols which normally fire live cartridges but which, by the provision in place of the usual breech mechanism of pellet-feeding means and means for controlling a supply of compressed air, are adapted to discharge pellets for practise purposes. According to the invention, the pellets 65 are fed from a tubular magazine 62 by a. pneumatically-operated push-rod 77 which during forward movement pushes the pellets into an auxiliary barrel 54 the compressed air being controlled by a member such as a piston 61 connected to the push-rod andforming part of the pneumatic drive therefor. In the form shown, the push-rod is carried by a frame 71 and has fast therewith the piston 61 and a smaller piston 60, the latter controlling the supply of compressed air through the pipe 67. On pressing the trigger 78 to release the frame 71, air passes to the right of the piston 61 to force the rod 77 forwardly against the action of a spring 56 to load a pellet, the air then passing through ports 76 and passage 59 to discharge the pellet. The parts are returned to the position shown by the spring when the pressure falls after discharge. The Specification as open to inspection under Sect. 91 also describes, with reference to Fig. 4 (Cancelled), a modified form of practise pneumatic gun for attachment to the cartridge chamber 33 of an existing machine gun. The practise barrel 35 is screwed into a plug 31 fitting the chamber 33. The plug has an annular extension supporting a carrier 26 for the pellets 40 which are discharged when aligned with the barrel 35 by compressed air admitted to a chamber 23. The pellet magazine 28 is supplied with compressed air to assist the feed, and the carrier 26 is rotated by a flexible shaft 18 geared to a motor 9 mounted on the stand 7 of the gun as shown in Fig. 1 (Cancelled). The motor through a cam device 11 also serves to reciprocate the gun on the stand 7 to simulate recoil. This subject-matter does not appear in the Specification as accepted.
