Title: Improvements in or relating to enclosed electric switch gear
IPC: H01H21/06
Filed: 1947-09-23
Abstract: 627,682. Switch cases and covers., WALSALL CONDUITS, Ltd., and COURT, R. A. B. Sept. 23, 1947, No. 25782 [Class 38(v)] To eliminate the manufacturing to fine limits of interlocking mechanism provided between the covers of a switch housing and 'the operating means for the switch, a lost-motion connection is incorporated in the operating means. The housing 10 has two compartments containing, respectively, a tumbler switch 11 and fuses 12 and enclosed by covers 13 pivoted at 14. Lugs 16 on the covers 13 co-operate with interlocking quadrants 19 pivoted on spindles 18 to the housing, the spindles having crank arms 20 coupled by a rod 21, such that when the operating handle 22 is moved to the open position, slots 26 in the quadrants 19 come opposite the lugs 16 and the covers 13 can be opened. The engagement of the lugs 16 in the slots 26 prevents closing of the switch 11 by the handle 22 when a cover is open, and when the handle is in the closed position, arcuate peripheries 24 of the quadrants 19 come beneath the lugs 16 and prevent opening of the covers. The spindle 18 associated with the switch compartment has an eccentric 27 co-operating with ears 28 of an arm 29 pivoted at 33 and having a forked end 30 engaging the switch dolly 31. The distance between the ears 28 is greater than the diameter of the eccentric 27, and the eccentric is so positioned on the spindle 18 relatively to the quadrants 19, that, when the handle 22 is moved to the " off " position, the switch is first opened, Fig..4, and then further movement of the handle brings the slots 26 beneath the lugs 16, but due to the lostmotion between the eccentric 27 and ears 28, the dolly 31 is not moved back to close the switch. Specifications 470,191 and 605,521 are referred to.

Title: Arrangements for producing thin bundles of electron rays from large surface cathodes
IPC: A61F13/00
Filed: 1934-09-07
Abstract: 443,844. Cathode-ray tubes. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, and ARDENNE, M. VON, 19 Jungfernstieg, Lichterfelde-Ost, both in Berlin. Sept. 7, 1934, No. 25803. Convention date, Sept. 8, 1933. [Class 39 (i)] Electrons from a large surface cathode are formed into a convergent beam and then into a parallel bundle of rays of small crosssection and the intensity of the rays is controlled by an intermediate electrode arranged in the path of the rays so that the straight lines of the electric field are not disturbed. A protective ring 1 surrounds the emissive cathode surface 2 to keep the lines of force perpendicular to the cathode at its edge. The cathode and ring may be planar with the electrons drawn off in parallel lines before being converged or may be curved convexly or, as shown, concavely to produce directly a convergent beam, the intensity control electrode 3 being curved. The convergent beam, before passing through the deflecting system, is converted into a parallel beam by a dispersing electron lens immediately in front of the focus 5 or by a converging lens after the focus or by shutters which form an acceleration field of parallel lines and the first of which is at or near the focus. The cross-section of the ray is determined by the shape of the cathode or shutters. Magnetic or electrostatic lenses may be used and may be cylindrical and formed by wire networks. Screening electrodes at potentials corresponding to the electron velocity at the electrodes may be used, for example, to screen the electron lenses from the deflecting system. The tube may contain gas fillings below 10<-3> mm. pressure to prevent straying of the rays in the parallel beam, hydrogen or argon or combined fillings at 10<-5> mm. being specified.

Title: Improvements in or relating to electric condenser arrangements
IPC: H01G4/06
Filed: 1925-10-19
Abstract: 246,799. Etablissements Merlin et Gerin, Soc. Anon. Jan. 30, 1925, [Convention date]. Condensers; transformers. - Relates to a condenser having guard rings intended to ensure insulation of the lead-in conductor of high-tension apparatus. A group of main capacities in series, Fig. 1, is used between the insulated conductor A and earthed support, these capacities ensuring uniform radial distribution of the tension. The effect of this is shown in Fig. 2, wherein the curve AB shows variations of the voltage gradient between the conductor A and the outside B when no intermediate armatures are used, and A<1>, B<1> shows the same with intermediate armatures. As the ends of the armatures end on a hyperbola a, b. Fig. 1, the axial distribution of tension is not uniform and the varying voltage gradient may give rise to arcing. To remedy this, there is used a further set of capacities, Fig. 4, in seriesparallel between the conductor and its support, so enabling a higher voltage to be employed on the conductor. The condensers may be incorporated in the terminal during winding, the dielectric being paper in which are inserted aluminium plates at the required intervals.

Filed: 1922-10-02
Abstract: 209,152. Pilkington Bros., Ltd., and Waldron, F. B. Oct. 2, 1922. Flat extended surfaces, surfacing and polishing- -In apparatus for the continuous grinding and polishing of plates of glass, in, which the plates are mounted on a series of tables moving continuously under grinding and polishing discs, the tables being removed after passing the last disc, and a new table added to the series, the tables are frictionally registered to prevent relative movement therebetween and the consequent breakage of the plates which overlap the juncture between two tables. The frictional registering is obtained by moving the tables by a drive applied to the last one added only, and communicated from one table to the next through the abutting ends; thus tables 3, 4 are the first in the series, and table 1 is the last one added, the drive, which is through a pinion 8 and rack 7, being applied to table 1 only. The pressure between the abutting ends of the tables is sufficient to prevent relative movement. The friction between the tables may be increased, to allow for the different grinding pressures at different sets of grinders, by shaping the ends of the tables to give greater intensity of pressure. Registering devices 9 may be provided.
