Title: Improvements in and relating to luminous indicators
IPC: H02B15/00
Filed: 1929-08-28
Abstract: 318,158. Akt.-Ges. Brown, Boveri, et Cie, (Assignees of Oesterreichische Brown, Boveri-Werk Akt.-Ges.). Aug. 28, 1928, [Convention date]. Selective signalling, apparatus.-Indicators as used for switchboards comprise an opaque panel with clear parts representing bus-bars 1, disconnecting and oil switches 2, 3, rectifier and transformers 5, 6, &c., and illuminating lamps contained in standard size cases 7. The cases are arranged in horizontal grid members 8, 9 which are made to hold an even or an odd number of cases, so as to allow of cases in adjacent rows being staggered. The grids have interengaging ends and are secured to vertical supports 10 behind which are walls for carrying the leads to the lamps. Each case is formed so that the observer does not see the lamp 12, Fig. 6. The upper surface 19 is white and formed as an Archimedian spiral with its origin in the lamp, the lower convex side is a matt black and the side walls are metallically reflecting. The cases are tapered so that there is sufficient space between them at the rear to accommodate the bars 8 and supports 9 and yet the front edges meet so as to avoid non- illuminated parts of the panel. Any measuring instruments incorporated in the panel are made an integral multiple of the size of the cases.

Title: Energy balanced drive of a rotary system at cyclically repeating continuously varying velocity
IPC: F16H55/08
Filed: 1959-07-30
Abstract: 889,538. Toothed gearing. HALLDEN MACHINE CO. July 30, 1959 [Sept. 16, 1958], No. 26247/59. Class 80 (1). [Also in Group XXII] Relates to a drive for a rotary system for severing, shearing, slotting, embossing, marking or printing, continuously and variably fed metallic, plastic or fabric stock, shown applied to the drive of a rotary shears 22 for severing sheet metal fed by independently driven rolls 28, wherein the rotary system is driven from a uniformly rotating input shaft 37 through means such as eccentric spur or bevel gears 74, 75, 76, which produce a cyclically varying output speed the phase of which can be adjusted to synchronize cutting with feed speed, said means also driving oppositely a counterbalance system including a flywheel 36 for balancing inertia loads. Instead of, as is usual, balancing the instantaneous inertia torques of the two opposed systems 22, 36, this invention designs the gears 74 ... 76 so that the sum of the kinetic energy of the two systems 22, 36 is, at any instant and given input speed, a constant, and the instantaneous torques themselves are unbalanced. The opposed systems thus have an equal rate of change of kinetic energy, and the Specification shows that this results in the application of a balanced torque to the input shaft 37 in spite of the fact that the individual torques of the two systems are unbalanced. The Specification includes a mathematical proof of the above and also of the design criteria for a set of eccentric wheels, together with a specific example. Harmonic kinetic energy and torque curves are also derived, the former being exactly and oppositely phased, the latter not. Specifications 800,307 and 889,537 are referred to.

Void [Published under Sect. 91 of the Acts]. [Class 79 (i).] A locomotive is driven by a Diesel engine which compresses air, the air passing into contact with and evaporating water, and the mixed air and steam thus produced passing to a motor directly coupled to the driving wheels. Fig. 1 shows apparatus in which the compressed air is passed from a perforated pipe 4 into a body of water, the mixed air and steam being collected in and removed from a dome 3 ; evaporating and superheating pipes 10, 11 in and above the water are traversed by the exhaust gases from the Diesel engine or from a burner 12 forming a reserve heat source. Fig. 2 shows a spray evaporator in which air and water pass in contrary directions through vessels 12, 13, only the upper vessel being traversed by the exhaust gas heating pipes. A part only of the compressed air may thus be treated, and afterwards mixed with the untreated part. In engines cooled by superheated water the steam thus generated may be added to the mixture. In normally cooled engines, the compressed air may be passed through the body of cooling water, the radiators being dispensed with.
