Title: Improvements in or relating to apparatus for viewing stereoscopic pictures
IPC: G03B35/16
Filed: 1923-01-23
Abstract: 206,056. Marshall, C. W. Jan. 23, 1923. Sterescopic kinematography.-Projected stereoscopic pictures are viewed through apparatus comprising louvres moved to permit of alternate vision with each eye, producing the effect of stereoscopic relief. The louvres are constructed of translucent material stretched on light frames and arranged parallel with one another. In operation, the louvres are oscillated or rotated to change the angle of inclination to the observer and to the screen. Louvres K are hinged vertically to a frame member A placed between the observer O and the screen P, and oscillated about hinges H<1> by tie rods B connected to a crank F on the shaft D rotated in synchronism with the display apparatus. In one modification the set of louvres is rotated about an horizontal axis parallel to the screen, and in a further modification a series of louvres with alternating inclinations are arranged on a disc rotated on an axis normal to the screen. Alternatively, pairs of louvre sets are mounted on the outer surface of an endless band passing over pulleys rotated in synchronism with the display apparatus.

Title: Means for generating reactive power
IPC: G05F1/70
Filed: 1972-01-17
Abstract: 1367571 Reactive current converters ALLMANNA SVENSKA ELEKTRISKA AB 17 Jan 1972 [18 Jan 1971] 2077/72 Heading H2F A reactive current converter comprises a pair of line-commutated converters A, B, connected across an A.C. line RST and having the D.C. sides connected in anti-parallel via a pair of inductors R1, R2. As described, power is supplied to the line RST by an inverter C, having a capacitor battery K. Reactive current is supplied by converters A, B, operating with differing control angles so that they respectively act as rectifier and inverter. Parts of inductors R1 and R2 may be saturable so that the inductance becomes decreased as the current increases. The reactive current may be monitored by transformers ST and converted by unit M into a reactive power signal, which is compared at J with a signal Pref representing desired reactive power, the resultant controlling the conduction angle of converters A, B. The arrangement is stated to result in reduced harmonic content compared with a single reactive current converter. In Fig. 4 (not shown) inductors are included in series with the source C so that automatic voltage regulation is achieved by control of reactive power. Alternatively, the unbalance in the line RST may be corrected by appropriate control of the control angles of converters A, B.

Title: Improvements in vacuum electric tube devices or valves for use in particular gain control circuits
IPC: H03G1/04
Filed: 1932-07-04
Abstract: 408,328. Thermionic valves. ROBINSON, E. Y., Garvary, Dryden Road, Bush Hill Park, Enfield, Middlesex, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. July 4, 1932, Nos. 2402/34 and 2403/34. Divided on 408,256. Drawings to Specification. [Class 39 (i).] For use in the gain-control method and circuits described in Specification 408,256, a thermionic valve has at least four grids consecutively interposed between the cathode and the anode, the second and fourth or the third and fifth grids and no others being connected together within or as part of the manufactured valve, for example, within the valve envelope or cap. The cathode may be connected within the valve to a grid adjacent the anode. In a valve with the third and fifth grids connected together and acting as a self-oscillating, mixing valve in a supersonic heterodyne receiver, the second grid may be replaced by an auxiliary anode which may be formed by the usual grid-supporting rods. In a modified similarly acting valve, the auxiliary anode co-operates only with extensions of the cathode and first grid, the cathode being coated in two parts. The low-potential grid adjacent the cathode and used as input grid, or the gain-control grid, may be non-uniform. Stray field between the input grid and the anode may be reduced by passing their leads through remote parts of the bulb and by extensions of the shielding or other intervening grid. The details described are identical with those in Specification 408,256. Specifications 134,542, [Class 39 (i)], 380,429, 385,968, 407,317, and 408,330 also are referred to.

Filed: 1944-02-09
Abstract: 576,634. Model railways. CERRI, F. DUSCHER-. Feb. 9, 1944, No. 2442. [Class 732 (iii)] [Also in Group XXX] In a toy or model railway a cross-switch with electric remote control is characterised in that it enables travel along four different tracks and is provided with intermediate conductor switch blades which lie between the conductor switch blades co-operating with the track rails, and which are movable simultaneously with, but in the opposite direction to the adjacent conductor switch blades co-operating with the track rails, by means of an electric impulse operating an electric actuating mechanism. Fig. 1 shows a plan view of the crossing, the track rails 2, 3 (in direction VY) co-operate with an intermediate rail 4 and the track rails 2a, 3a (in direction XW) co-operate with an intermediate rail 4a. The conductor switch blades 8s, 9B, 7B and 8a, 9a, 7a co-operate with the track rails 2, 3 and 4 respectively, while the conductor switch blades 8A, 9A, 7A and 8b, 9b, 7b co-operate with the track rails 2a, 3a and 4a respectively. The intermediate conductor switch blades 7A, 7B, 7a, 7b have points 6 and 6a. The parts surrounding the centre piece M and in part lying beneath it are of insulating material and are provided with channels for guiding the wheel flanges to avoid derailment. Platforms N arranged laterally of the centre piece M have guide faces F which are so shaped that they ensure perfect guidance of the flanges of the outer wheels of the train. When the conductor switch blades are in the position shown in Fig. 1, they permit of travel in the direction XY and when in the position shown in Fig. 7, they permit of travel in the direction XW, the position and electrical contacts of the top conductor switch blades having been altered. The mechanical actuation of the individual parts of the switch and simultaneously of the indicators of a signal lamp S (Fig. 1) is effected by a lever system which is controlled by an electricallyoperated actuating mechanism consisting of two parts A and B. Each part A and B comprises a magnet coil 29, Fig. 3, and a fixed laminated core 30 which operates two armatures 31, 32 so interconnected mechanically by means of a link 33 that the forces of attraction are substantially additive. The actuating mechanism A operates the upper conductor switch blades and mechanism B the lower conductor switch blades.
