Title: Transit-time tubes
IPC: H01J25/38
Filed: 1973-06-08
Abstract: 1439466 Travelling-wave tubes SIEMENS AG 8 June 1973 [10 Aug 1972] 27313/73 Heading H1D The delay line of a travelling-wave tube arranged between an electron gun and a collector has sections exhibiting different values of delay per unit length, one section having a decreased value compared with the section adjacent the gun, whereby phase distortion is reduced, and the resulting decrease in efficiency being compensated for by the addition at the collector end of a further section having an increased value of delay per unit length compared with that adjacent the gun. As described, the delay line is a helix, and the first two sections are joined in a region of attenuation. The sections may. alternatively, taper gradually into one another, and the change of delay value may be produced by a change of cross-section, or by the introduction of dielectric material, rather than by a change of pitch.

Title: Improvements in or relating to a windshield washer
IPC: B60S1/48
Filed: 1953-10-07
Abstract: 734,659. Diaphragm pumps. TRICO PRODUCTS CORPORATION. Oct. 7, 1953 [Oct. 16, 1952], No. 27569/53. Class 102 (1). [Also in Group XXIII] Relates to a pump for a windshield washer (see Group XXIII), in which the pump is in the form of a bellows 14 having an elastic wall 17 distensible under liquid pressure resulting from the application of an external distorting force to the bellows, the wall 17 when so distended serving to maintain pressure on the liquid within the bellows and to provide a continuous delivery of liquid when the elastic wall is distended. The bellows 14, made of natural or synthetic rubber is connected by a conduit 13 to a reservoir (not shown) and to a nozzle (not shown) by conduits through a check valve having the usual non-return ball valves. Referring to Fig. 2, the bellows has a heavy top wall 15, and a thick bottom wall 16, clamped to a tubular member 19 connected to the conduit 13, the top and bottom walls being connected by the thin elastic wall 17. When the bellows is compressed by foot pressure as shown in Fig. 3, the liquid in the bellows is placed under pressure owing to the restricted capacity of a discharge passage 22 in the member 19. This liquid pressure distends the wall 17 to the full line position in Fig. 3. The restoring force of the side wall maintains the pressure and continues to force liquid through the passage 22 as shown in broken line in Fig. 3. Bosses 36 on the wall 15 prevent the wall closing-off the passage 22.

Patent GB-424822-A (GB)
Title: Improvements in or relating to x-ray tubes having an anode adapted to move when in use
IPC: H01J35/24
Filed: 1934-09-28
Abstract: 424,822. R÷ntgen-ray tubes. MULLER AKT.-GES., C. H. F., 24, R÷ntgenstrasse, Hamburg, Germany. Sept. 28, 1934, No. 27849. Convention date, Sept. 30, 1933. [Class 39 (i)] In an X-ray tube having an anode moving relatively to the electron beam, the electron density in the beam is non-uniform so that the specific load on the focal spot decreases in the direction of movement of the anode. The anode 1, Fig. 1, moves in the direction of the arrow and the electron density of the beam from the helical cathode 2 decreases from left to right. Each point of the anode surface is heavily loaded when it first enters the focal spot and its temperature is raised to the maximum permissible temperature more rapidly than would be the case if the electron beam were uniform. The total load is thus increased without overheating the anode. The non- uniform emission may be produced by non- uniform cathode temperatures, the left-hand side of the coils of the filament 2 being kept at a higher temperature than the right-hand side by making the left-hand side 4 of the recess in the focusing device 3 a better heat reflector than the right hand side, which may be spaced away from the filament 2 as shown. In a modification (Fig. 2, not shown), the recess in the focusing device is symmetrical and the non-uniform temperatures are produced by etching or otherwise reducing the diameter of the filament at the left-hand side, the filament being an oval helix or being bent to and fro in loops. In further modifications, (Figs. 3 and 4, not shown), the cathode consists of parallel filaments of different resistance, for example, of the same material and different diameters, the temperature of the thickest filament being the greatest if the filaments are connected in parallel and the least if they are connected in series. In another modification, (Fig. 5, not shown), the non-uniform electron beam is produced by a grid of non-uniform mesh in front of the cathode and at the cathode or a slightly lower potential. The non-uniform beam may also be produced by increasing the emission surface at the left-hand side. A helical or looped filament, Fig. 6, has additional small loops 13, or a small helix is arranged eccentrically in a larger helix, (Figs. 7 and 8, not shown). In a further modification, an additional filament 19, Fig. 9, screened from the anode 1, heats the left-hand side of the filament 18 and also adds its emission to the left-hand part of the beam. The anode may be rotated by a magnetic stator external to the tube, or may be moved with the tube whilst keeping the cathode stationary, or the electron beam may be deflected electrically or magnetically and the anode moved relatively thereto.

Title: Improvements in and relating to flying machines, helicopters and the like
IPC: B64C27/04
Filed: 1927-10-20
Abstract: 279,470. Perrin, E. A. Oct. 22, 1926, [Convention date]. . Screw and like propellers.-A helicopter supported by a single screw is provided with means for cyclically varying the pitch of the screw blades and means for varying the pitch of the screw as a whole. The blades of the propeller are pivoted about a tubular cross-piece 81 on a tubular shaft 54 which is surrounded near its lower end by a sleeve 59 carrying pawls 56 engaging a ratchet on a casing integral with a gear wheel 53 in mesh with a gear wheel 52 on the engine shaft. The sleeve 59 has a ring 60 notches to receive the ends of two levers 66 pivoted about a belt 67 extending through the shaft 54 and the lower ends of the levers engage inclined slots 68 in a sleeve 69 which can slide without relative rotation upon the shaft 54. When. this sleeve 69 is moved by a hand-lever 72 the sleeve 59 is turned relatively to the shaft 54 and this motion is transmitted to a tubular shaft 74 by means of a bolt 73 extending through oval holes in the shaft 54. The upper end of the shaft 74 carries a bail having cranked portions entering a ring 76 which carries arm 77 connected by short links to the under surfaces of the screw blades, so that the rotary movement of the shaft 74 is transmitted to the ring 76 and the pitch of the blades is varied equally. A joystick M is connected bv a link 141 to arm ML on a cross shaft having a lever 119 which moves a rod MLV connected through levers 131, 132 and rod OT to mechanism for moving a, frame 145, Fig. 13. This frame carries rollers 144 bearing on the ring 76 whereby the ring is displaced to cause a cyclical and opposite variation of the pitch of the screw blades which is a maximum as the blades pass through the transverse plane of the machine. This frame is also displaced through a, conection to the upper end of' the lever 131 when the hand-wheel 109 is turned, but at the, same time the bell crank 115 moves the rod MLV nearer to or further from the pivot of the lever 119 so that at high speeds the rod MLV is not movable by the joy-stick M. Lateral movements of the joystick M are transmitted through a rod 140, arm MT, and rod OL to arms 148, Fig. 13, connected to a sleeve 149 through which rods on the frame 145 can slide when moved by the rod OT. Movement of the rod OL moves the frame in a direction at right angles to that caused by the rod OT.
