Title: A stroboscopic or flash-photography system
IPC: H01J17/00
Filed: 1956-11-06
Abstract: 829,022. Discharge lamps. GERMESHAUSEN, K. J. Nov. 6, 1956 [July 17, 1956], No. 33916/56. Class 39(1). [Also in Group XXXV] A cold-cathode gaseous-discharge tube, for use in stroboscopic or flash-photography systems, comprises a plurality of like control or trigger electrodes having operative portions spaced at substantially equal intervals along a straight line between an anode and a cathode, both of which are of the cold-cathode type and are formed of sintered material. In operation anode to cathode discharges are initiated and confined to this line by raising the control electrodes to a potential greater than the potential applied between anode and cathode which latter potential is of itself made insufficient to produce a discharge between anode and cathode. As shown, the trigger electrodes 21, 23, 25, 27 and 29 extend inclinedly into the space between the anode 5 or cathode 7 so that the discharge impedance between successive electrodes is a minimum along the line L, or adjacent electrodes may enter the space from opposite sides, or alternatively the trigger electrodes may be supported by an insulating member extending between the anode and cathode, Fig. 3 (not shown). their lower ends being provided with insulating coverings. Either or both of the electrodes 21, 29 may be provided with insulating coverings 21<SP>1</SP> 29<SP>1</SP> to reduce the initial arc break-down to the adjacent anode or cathode. Particle trapping screens 5<SP>1</SP>, 7<SP>1</SP> may be provided adjacent the anode and cathode as described in Specification 818,505, the anode and cathode preferably being sintered coldcathode type electrodes. The gas filling may be xenon at a pressure of ¢ to 3 atmospheres, adjacent electrodes being spaced # in. apart along the line L. The tube may be disposed in a socket mounted in the focal region of forward or rearward parabolic reflectors to provide directive beams of flashing light, Fig. 5 (not shown). The lead-in connections to the trigger electrodes are each provided with sufficient isolating impedance, such as a capacitor or coaxial-line section, so that successive break-downs occur in series between consecutive electrodes. The outer ends of the lead-in connections are connected together and to a trigger circuit (see Group XXXV).

Filed: 1935-12-16
Abstract: 467,242. Cam mechanism ; engine valve gear. SANDERS, G. A. P., and MIELER, H. P. E. Dec. 16, 1935, No. 34916. [Class 80 (iii)] [Also in Group XXVII] Cam-operated rocker-mechanism, particularly applicable to valve gear of internal-combustion engines, comprises a rocker subjected to the action of two cams which are coupled together so that one cam performs a multiple of the revolutions of the other, the slow-speed cam providing, in its operative position, a stationary or lifting fulcrum about which the high-speed cam can rotate the rocker to move the tappet, the high-speed cam being ineffective to operate the tappet if the slow-speed cam is in its inoperative position. A shaft 1 carries a cam 2 for actuating the inlet, and a cam 3 for the exhaust valve. This shaft is coupled by 2 to 1 gearing 4, 5 with a shaft 5 having cams 7, 8 for the inlet and exhaust. A rocker 9 is pivoted at 10 to an arm 11 pivoted to the housing 17, the end 15 of the rocker actuating the valve stem 16, the other end 13 being in contact with the cam 2. In order that the rocker 9 may lift the valve stem 16, it is necessary that the cam 7 should lift the member 11 into its upper position. In a four-stroke engine, the slower cam could rotate at half engine speed. The high speed shaft would rotate at engine speed and only actuate the tappet at such times as the slower cam came into position of maximum lift. In a modification, Fig. 2, there is only one rocker 25 with pin-and-slot connection 26, 27 with the casing 28, and it is moved both by a high speed cam 23 and by a low speed cam 30. Specification 2121/06, [Class 7], is referred to.

Title: Magnetic switching device
IPC: H03K19/16
Filed: 1961-09-29
Abstract: 992,404. Electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 29, 1961 [Oct. 13, 1960], No. 35315/61. Heading G4H. [Also in Division H3] In order to increase the number of facilities of a magnetic switching device, both the input and output windings are wound in accordance with a combination code, the arrangement being such that a selected combination of input windings produces a set flux change in at least one group of elements and such a change produces a resultant voltage in at least one but not all the associated output windings. Fig. 1 shows the simplest form of a switch of the so-called Constantine type described in Specification 909, 899. The basic matrix pattern for this switch is where each column represents a magnetic element and each row an input winding. The 1 and 0 indicate the sense of the coupling with the core. The particular arrangement shown has two sets of cores 14, 16 and 22, 24, of which the top pair represent the two element Constantine switch and the bottom pair another. The number of windings on each core is doubled so as to avoid using pulses in two directions on a single lead. Hence four conductors link each pair of cores. The present arrangement differs from prior arrangements in that, instead of a single output conductor associated with each magnetic core, a Constantine pattern consisting of windings 32, 34 linking the two cores 14, 22 and windings 36, 38 linking cores 16, 24 is provided. By selecting four input windings, two linking each pair of cores, a positive or negative output may be produced in one of leads 32-38. The magnetic elements should have zero remanence but if they have not, those that are driven in a particular direction are reset by a write-in current on a complimentarily wound winding but may be reset by a D.C. bias winding. A higher order Constantine winding may be used on both the input and output. The Specification describes the application of the invention to a so-called Marcus winding. The winding pattern for a four input, three core switch is and Fig. 2 shows an arrangement in which two such sets of three core, four input switches are interconnected by an output pattern in the Constantine manner. The application of the invention to an arrangement described by Chien in U.S.A.Specification 3,145,306 is also described. In one of the patterns two sets of four windings link each of two sets of three cores and the output windings are again a Constantine pattern. Higher order Constantine and Chien windings may also be combined (Figs. 4 and 5, not shown). It is not necessary that all the input windings couple all the elements in a corresponding row of elements and an arrangement is described with reference to Fig. 9, not shown, where pairs of elements are coupled by a straightforward Constantine output winding but the input windings are arranged in accordance with a standard computer code pattern.
