Patent GB-1582556-A (GB)
Title: Arrangement in liquid sprayer containers
IPC: B05B7/04
Filed: 1977-05-03
Abstract: The nebuliser has a hand-operable valve mechanism (11, 12), consisting of a seal (11) which is placed against a membrane (12) in the neutral position, as well as a hood (17). The pressure occurring when the hood is fitted onto the nebuliser head (8) is passed through the spray nozzle (9) and a duct (14) up to the seal (11), raises the latter and thus passes into the interior of the container (1), whereupon the seal (11) immediately closes again. It is only raised again when the nozzle (9) is pressed down after removal of the hood (17) and, in doing so, pushes the tubular section (10) connected to the seal (11) downwards. The pressure in the container (1) can then propel the liquid (2) into a tube (7) and through the latter to the spray nozzle (9) where it is nebulised. In this way, with only one pumping movement a nebulisation is obtained which is maintained until the pressure in the container (1) is reduced. <IMAGE>

Heading F2Q. In a planetary type gear train using straight or single helically toothed spur gears, the non- planetary elements are flexibly coupled to their respective torque transmitting or reacting members and only one element of the train is axially located relative to its torque transmitting or reacting member, the other elements being axially located by pressure rings 17-20, rigid with both ends of the non-planetary elements, which engage the end faces of the planet teeth and plain annular areas 24 within the dedendum circles thereof. As shown, an annulus gear 6 and a sun gear 11 are coupled to a fixed casing 1 and a shaft 12 respectively by splined coupling sleeves 7, 13 for limited universal movement relative thereto. Circlips 16 axially locate the annulus 6. Ring 20 is shrunk on to the hub of sun 11 and rings 17-19 are secured to the gear ends by screws 27. The ring bearing faces and the areas 24 are frustoconical, while the tooth ends 26 of the planets are convex and, in plan, rounded at their corners 29. The planet carrier may be the fixed gear element.

Title: Improvements in or relating to digital synchronisation arrangements for time multiplex transmission system receivers
IPC: H04L7/08
Filed: 1965-05-04
Abstract: 1,102,715. Multiplex pulse signalling. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 4 May, 1965 [8 May, 1964], No. 18781/65. Addition to 1,069,650. Heading H4L. The system for synchronizing a receiver in the time division multiplex system disclosed in the parent Specification is modified by the inclusion of an improved pulse regenerating arrangement. An incoming pulse applied at E sets a trigger ST which starts a counter TZ, controlled by pulses such that n pulses occur for each incoming pulse from a local clock pulse generator (not shown) and also changes over a bi-stable FF. The counter operates until it reaches a n preset position - when if the trigger ST has in 2 the meantime been returned it changes back the bi-stable FF and any character which has been stored by a shift register SR is erased. The counter also is returned to its zero position in order to prevent the identification of an extended pulse as two pulses. If the trigger ST has not been returned when the counter TZ reaches position n/2 the counter begins a further   count up to n/2 without changing back FF and the received pulse will be evaluated as correct. The shift register SR is stepped by a counter BZ controlled by the local clock pulses.

Abstract: 907,040. Electron beam apparatus. BUSH & RANK CINTEL Ltd. May 29, 1961 [May 27, 1960], No. 18789/60. Class 39 (1). An electronic switching tube comprises a planar electron source 2, Fig. 4, disposed perpendicular to an axis, a plurality of electronpermeable control electrodes 5 disposed symmetrically about the axis in a plane perpendicular thereto, an anode 7 opposed to the electron source and control electrodes and coextensive therewith, an output electrode 6 disposed to receive electrons passing through any of the control electrodes, and a collector electrode 8 disposed to receive electrons rejected by the control electrodes. Within the space bounded by the electron source, control electrodes and anode there is provided a magnetic field perpendicular to the axis, the direction of this field being variable so as to cause electrons to impinge upon the control electrodes in a desired sequence, whereby signals applied to the control electrodes appear in this sequence at the output electrode. Alternatively, the control electrodes 5 may be replaced by a single annular, electron-permeable control electrode and the output electrode 6 by a plurality of output electrodes disposed to receive electrons passing through different parts of the annular control electrode so that variation of the direction of the magnetic field causes signals applied to the control electrode to appear in a desired sequence at the output electrodes. As shown, the electron source is surrounded by a guard ring 4 which may be planar, or parttoroidal, Fig. 5, the latter in conjunction with a centrally-protuberant anode 7, providing a focusing effect, Fig. 6 (not shown). The magnetic field may be produced by a rotatable permanent magnet, Fig. 3 (not shown), or by a multipolar yoke carrying windings fed with dephased currents.

Abstract: 165,668. Knight, A. B. July 6, 1920. Disc apparatus; driving-devices; supplying fluids; work-holders; spindle-mountings. - A machine for grinding glassware, especially the cracked-off ends of tumblers &c., comprises a number of similar units, all the grinders being driven by a single belt. The machine shown has three units, each of which comprises a grinding- wheel 43, Fig. 5, and a holder 63 for the drinking-glass 45 being ground. Each grinder 43 is carried by a chuck 42 on the end of a tubular spindle 19, which is supported in bearings 17 and is rotated by a pulley 20 between ball bearings 22. Water is supplied through a pipe 32 concentric with the spindle 19, and the waste returns through the spindle, the coned end 23 of it throwing the waste away from the bearings 17 into a housing 26. The ring 63 is lined with leather or other fibrous material and forms part of a chuck 62 on a carriage 56, which is carried by a pair of rods 46. These rods are slidable.in sleeves 48, Fig. 2, carried by one of the bearings 17, and in sleeves 51 on a bracket 52. The carriage 56 is moved towards the grinder by weights 111, and away therefrom by a. treadle 100. The levers connecting each treadle to its corresponding carriage are so proportioned that equal depressions of the treadles produce equal movements of the carriages. The forward movement of the carriage 56 is limited by an adjustable nut 71 on a rod 67 sliding through an aperture in the bracket 52 and attached to the carriage 56. A latch 74 on the bracket 52 can be turned to engage a. flattened portion 72 of the rod 67 and hold the carriage 56 in its inoperative position. The bracket 52 carries an adjustable rod 64, Fig. 5, which passes through the carriage 56 and contacts with the rear of the work as the carriage is withdrawn, thereby ejecting the work. The several units are driven from a motor 105, Fig. 3, by a belt 21 passing over the pulleys 20 and under idler pulleys 109. Openings 106 in the support 10 allow the belt to pass therethrough, and are provided with upstanding edges 107 to prevent overflow of water.
