Title: Improvements in or relating to velocity-modulated amplifier tubes
IPC: H01J25/38
Filed: 1966-03-11
Abstract: 1,143,441. Velocity-modulated tubes. SIEMENS A.G. 11 March, 1966 [12 March, 1965], No. 10689/66. Heading H1D. In a hybrid amplifier tube having a delay line input circuit and a cavity resonator output circuit 6 separated by a drift space 5, the delay line is in two sections, in the first of which, l 1 , normal travelling wave tube amplification occurs, with consequent production of a slow space charge wave on the electron beam, while the second section, l 2  is of increased periodic length, to give a phase velocity greater than that of the electron beam, whereby the amplified signal on the delay line, instead of being wasted, produces a fast space charge wave on the electron beam, increasing the density modulation of the latter by the input circuit, and hence the efficiency of the tube. The periodic length of the second section is increased by 20% to 70% of that of the first, and the length of the second section corresponds approximately to the Kompfner dip condition. The two sections of the delay line may be constituted by helices of different pitch, joined by a coupling section of gradually changing pitch to avoid reflections, and the second section may exhibit a periodic variation of pitch (Figs. 2 and 3, not shown). A hollow electron beam (Fig. 4, not shown) is employed, the diameter of which is reduced prior to entry into the cavity resonator, by accelerating the beam by a potential difference applied between an electrode (9) terminating the delay line and the drift tube (10), and by increasing the focusing magnetic field over the same region.

Title: Heat pump
IPC: F25B21/00
Filed: 1957-04-02
Abstract: 808,054. Thermoelectric devices. CARROLL, R. L. April 2, 1957, No. 10721/57. Class 37. [Also in Group XIII] Two conductors 3 and 5, preferably hollow, and the cross-section of the latter being about ten times that of the former, are connected as shown in Fig. 1 and are surrounded by heat insulation 23 leaving chambers 4 and 6 at the junctions of the two conductors. The conductors are cooled to below their transitional temperature (at which they become superconductive) and a direct current generator causes current flow in a clockwise direction in the circuit. In the super-conductive state the electrons forming the current flow in a sheath about the conductors and, on passing from the thin to the thick conductor, slow down in attaining a less dense distribution. It is stated that, since electrons absorb energy when slowing down, cold is generated at the junction 7. Similarly heat is generated at junction 9 and liquid helium is contained in the chamber 6 to cool the junction. The purpose of the type of connection between the conductors 3 and 5 shown in the Figure is to induce the electrons to cross the junctions between the metals while passing from the outside of conductor 3 to the outside of conductor 5, thus causing, in addition to the effect described above, a Peltier effect. A list of suitable conductors is given.

Abstract: 104,458. Wiesengrund, B. Aug. 1, 1916. Tooled gearing. - In toothed reduction gearing for driving a shaft from two or more motors, each high-speed motor shaft drives a separate intermediate shaft which is geared to the driven shaft, the high or low speed gearing, or both, being duplicated. Motors may also be connected to the intermediate shafts. In the form shown in Fig. 4, pinions 1, 2, 1a, 2a on the high-speed shafts gear with wheels 6, 6a, 7, 7a on the intermediate shafts, which carry pinions 9, 8 gearing with the wheel 10 un the driven shaft. The gearing 8, 9, 10 may be duplicated, and, in this case, the high-speed gearing may be either single, or in duplicate as shown. The motors may comprise internal-combustion engines, turbines, or electric motors, and may be all of one type or may be combined in any manner. Each motor may drive through gearing of different ratio. Motors may be connected up to the intermediate shafts, for instance in the case of a submarine, in which oil-engines on the intermediate shafts drive the driven shaft and at the same time drive electric motors on the high-speed shafts as generators. By the use of clutches, the electric motors may be used for driving during submersion. Additional bearings 12, 13 may be arranged between the pinions or wheels on any of the shafts.

Title: Heat sealing plastic film
Inventor: ARSCOTT JOHN ROWLAND
IPC: B29C65/02
Filed: 1965-03-16
Abstract: 1,090,575. Seaming non-metallic sheet material. IMPERIAL CHEMICAL INDUSTRIES Ltd. Feb. 7, 1966 [March 16, 1965], No. 11065/65. Heading B5K. Apparatus for sealing together at least two films 6 of thermoplastic synthetic resin comprises two pairs of jaws 2 capable of clamping the films 6 together in a plane, the jaws of one of the pairs being fitted with sponge-like material, and a metal element 5 with means for electrically heating it to a temperature causing emission of radiant heat and mounted to be moved between the two pairs of jaws 2 towards and away from the central point between the jaws 2. The jaws 2 are formed on two channel-section clamps 1. The limbs of the upper clamp 1 are provided with pads 3 of sponge rubber or flexible foamed plastic material. The element 5 runs along the length of the channel of the lower clamp 1, as shown, or the upper clamp. The element 5 is held taut by springs which will compensate for any expansion thereof as its temperature increases and may comprise a thin high resistance wire heated by passage of current therethrough. In use, the clamps 1 are brought together to close the jaws 2 on to the films 6. The element 5, heated to a temperature sufficient for it to melt the films 6 by radiation, is raised to an upper position, Fig. 2 (not shown), and maintained in this position until the films fuse together and form molten beads 7. The element 5 returns to its initial position, the clamps 1 open and the beads 7 solidify. The current may pass through the element 5 only when the clamps 1 are closed and/or in the process of closing, or the element 5 may be continuously heated. In the latter case, the lower position of the element 5 must be a sufficient distance from the upper position so that the heat being continually emitted does not affect the films 6 whilst the element is in the lower position. In modifications, the element 15 has a triangular cross-section. Figs. 4-6 (all not shown), and the clamp 1 which does not contain the element may contain an anvil 17, Figs. 7-9 (all not shown), biased by a spring 18 towards the central position between the clamps 1. In a further modification, Fig. 3 (not shown), for producing L-shaped seals, the apparatus comprises two channel-section limbs joined together to form an L. The two elements 5 are preferably connected in parallel in the same electrical circuit and the resistivity of the circuit to the point of contact 10 of the elements should be balanced. Compensating resistances 9 are connected to each element 5. Springs 11 mounted in insulated terminal blocks hold the elements 5 taut.
