Title: Improvements in or relating to electron discharge devices
Inventor: GARNETT WILLIAM BIRLEY
IPC: H01J25/08
Filed: 1951-07-24
Abstract: 692,841. Making electric components; soldering. STANDARD TELEPHONES & CABLES, Ltd. July 24, 1951, No. 17512/51. Classes 83 (ii) and 83 (iv). [Also in Group XL (a)] In a velocity-modulated tube of the coaxial line type the outer metal cylinder is formed with diametricallyopposite longitudinal slots for passage of the electron beam and metal plates to form the fins are positioned in the slots to ensure in the completed resonator accurate spacing from the fins on the central conductor, soldered in position and then the excess lengths of fin projecting from the outside of the outer conductor are removed. The fins are assembled with the outer conductor as shown in Fig. 3, together with rings of solder 13, 14. In one method the fins are spaced and aligned by pressing them against the central portion of a jig having a shank fitting in an aperture in the lower (closed) end of the cylinder and a circular flange engaging the cylinder near its open end. The rings of solder are then melted to secure the fins in position and the outwardly projecting portions sheared off flush with the surface. In an alternative method the inner conductor comprising strips 5 and 6, Fig. 2, welded to spacers 7, 8, is inserted in the aperture at the lower end of cylinder 1, the fins 12 are placed loosely in position in the slots and the drift space in the inner conductor aligned with the slots in the outer conductor by inserting a mandrel through them. The inner and outer conductors are then brazed together, removable spacers placed against members 7, 8 and the fins 12 pushed in to rest on the spacers. After the soldering operation the mandrel and spacers are removed. The inner conductor is held in correct spaced relation at its upper end by an insulating washer held between two metal rings, the lower ring 15 being shown in Fig. 3. The device is capacitatively coupled to an external circuit by disc 18, Fig. 6, supported on a short post held between strips 5, 6, Fig. 2. In the final assembly of the tube a metal disc 20 is sealed between envelope portions 21, 22 and the resonator and electrode assembly held between mica spacers 24, 25, 26 and carried by leads sealed through glass base 28 is introduced into the envelope 21, 22 and the glass base 28 sealed to the remainder of the envelope. During processing and exhausting the resonator and disc 20 are raised to such a temperature as to melt a tin ring 29 fitted over the upper end of the resonator to secure it to the disc 20. The cylinder 1 is preferably drawn or spun from sheet-metal or may be machined from a solid block, and is of alloy known under the Registered Trade Mark " Ferry." The strips 5, 6, Fig. 2, are of copper-plated " Ferry," and may have stiffening ridges 11. The beam is of rectangular section. The inner conductor fits in an aperture in a closed end integral with the resonator.

Title: Improvements in supersonic axial-flow compressors
Inventor: SCHWAAR PIERRE GEORGES
IPC: F04D21/00
Filed: 1957-06-04
Abstract: 816,811. Axial-flow compressors. SOC. NATIONALE D' ETUDE ET DE CON- .STRUCTION DE MOTEURS D' AVIATION. June 4, 1957 [June 11, 1956], No. 17761/57. Class 110 (1). A supersonic axial-flow compressor comprises a rotary blade ring in which the axial component of the absolute discharge velocity is supersonic, conversion of kinetic energy into pressure energy taking place in a stationary annular diffuser extending downstream of the ring, the conversion being due to the formation of a shock-wave downstream of which the flow becomes subsonic. The absolute discharge velocity may be purely axial to give a normal shock-wave or may be inclined to give an oblique shock-wave. In the latter case, blades may be provided at the outlet of the diffuser, to remove the whirl. In the compressor shown, the air passes through stationary guide blading 2 and contra-rotating impeller blading 6, 7, and the shock-wave 17 occurs in a bladeless annular diffuser passage 16 at, it may be, the narrowest part 18 of the passage. The convergent part of the passage upstream of the throat 18 forms a supersonic diffuser. The relative velocity at the blades 6 is subsonic at the roots with a Mach number between, say, 0.7 and 1.2, and supersonic at the tips with a Mach number between, say, 1.2 and 1.6, while the relative velocity at the blades 7 is wholly supersonic. Radial struts 5 are provided. The two impellers may be rotated in opposite directions by two oppositely-rotating turbine stages. Alternatively, as shown, the driving-shaft 9 drives the second impeller directly through a splined connection 10 and drives the first. impeller indirectly through a splined connection 11 and reversing gear 13. The boundary layer may be controlled by suction through porous walls of the diffuser 16 or through slots in the walls.

Title: Improvements in multiple unit, or gang, mowing machines
IPC: A01D75/30
Filed: 1922-06-30
Abstract: 207,571. Townsend, S. P. June 30, 1922. Lawn-mowers.-Relates to rotary-cutter lawnmowers of the kind described in Specifications 112,820 and 140,618, in which one of the cutter units is positioned to the rear and mainly at one side of another cutter unit and the driving-shaft extends between the cutter units and is driven from one or both of the ground rollers. The invention consists in the application to a twin rotary-cutter machine, such as shown in Fig. 2, of particular driving gear for driving the cutter units from the shaft 4. This shaft extends through a fixed casing 3 rigid with the loose side plates 1<a>, Fig. 3, of the ground rollers 1, and it is driven by internally-toothed wheels 6 gearing with the pinions 5. Loosely mounted on the shaft 4 are bevel pinions 43 in gear with pinions 44 for driving the front and rear shafts 40, and the pinions 43 are rotatable with the shaft 4 by operating the clutch elements 46, 47 through levers 48, 49. Each shaft 40 is telescopic and has universal joint connections with pinions 36 driving the pinions 35 of the cutter units 20, 21. Attached to the casing 3 is a rear cross-frame member 8, on which are supported two longitudinal frame members 10, 11, 12. Front supporting-wheels are mounted on the members 10, 11, and to the front bar 9 is attached a pair of traction shafts 19. The front bar 22 of each cutter unit is pivotally connected to the frame of the machine by a ball joint 25, Fig. 7, and loose side connections 32 permit each cutter unit to oscillate abount the joint 25. This arrangement of gearing and connections with the frame allows each cutter unit to be swung clear of the ground and rendered inoperative. This movement is effected through levers 61, 66 provided with pawls 62 engaging ratchet segments 63 to secure the parts in an adjusted position. Operation of the lever 61 lifts a roller 55 through links 54 - - 58, the roller engaging a side plate 23 to depress the roller 24 as the front cutter is raised. A similar movement of the rear cutter is effected by the operation of the lever 66 and link connections 67 - - 72. In a modified construction, both of the ground rollers are placed together so as to rotate as a single member, the other end of the shaft 4 being supported by a castor wheel.

Title: A method and device for operating starting-air compressors for marine internal combustion engines
IPC: F02B33/00
Filed: 1928-06-22
Abstract: 311,132. Hansen, P. June 22, 1928. Starling.-Cornpressed air for starting marine engines is supplied by a compressor driven by an auxiliary Diesel engine with solid injection, the compressor being arranged to give a full yield only when the pressure in the starting-air reservoir is below normal, and the compression space being increased by the addition of one or more expansion chambers when the reservoir pressure is restored to normal, so that the compressor then runs light. The auxiliary engine can thus be kept continually running and used to drive an electric generator for the operation of ship's machinery, lighting, &c. In one form, Fig. 1, a three-cylinder auxiliary engine a drives a dynamo c and a two-stage air compressor d, e having an inter-cooler q and supplying starting air to a reservoir p. When the reservoir p is fully charged, the compressor cylinders are connected to expansion chambers h, j by opening valves i, k connected to a lever l actuated by a hand wheel n having a screw spindle. In a modification, Fig. 3, only the lowpressure cylinder d is provided with an expansion chamber h, and the pipe o connecting the highpressure cylinder e to the reservoir p is provided with a double-seated valve r connected to the valve i. When the valve i is closed, the valve s seats at t and the pipe o is connected through a pipe o to the reservoir p; when the valve i is open, the valve s shuts off the pipe o and opens the pipe o to the atmosphere through a check valve u. In a further modification, the expansion chamber h, Fig. 3, is omitted and the inter-cooler q is used as an expansion chamber; when working with reduced yield, a bye-pass valve is opened to connect the low-pressure cylinder to the cooler, or the outlet valve of the low-pressure cylinder is held open. The bye-pass valve may be connected to a blow-off valve such as r, Fig. 3, in the outlet pipe of the high-pressure cylinder.
