Title: Improvements in or relating to driving gear for swash type engines
IPC: F16H23/08
Filed: 1933-05-24
Abstract: 419,226. Driving-gear. NEVATT, C. G., and KINGSTON, E. G., c/o Bristol Tramways & Carriage Co., Clare Street House, Bristol. May 24, 1933, No. 15051. [Class 7 (ii).] In engines with cylinders parallel to the crank shaft, piston movement is transmitted to an inclined crank pin 10 through an oscillating hollow cylinder 12 mounted around the crank pin and having arms 14 universally-jointed to the connecting rods 16. Rotation of the cylinder 12 is prevented by the engagement of bevel wheels 19, 20, the wheel 19 being secured to the rim 13 of the cylinder and the wheel 20 to a threearmed spider passing through slots 23 and anchored in the casing. The wheel 20 may be mounted on a part of the crank-pin co-axial with the crank-shaft, or both wheels 19, 20 may be external to the cylinder, the wheel 20 being secured to an internal flange in the casing and the wheel 19 to a disc integral with the rim 13. The apices of the pitch cones of both wheels lie on the intersection of the axes of the crank pin and crank shaft. Specification 327,161, [Class 7 (ii)], is referred to.

Title: Improvements in electrodes for discharge tubes
IPC: H01J1/14
Filed: 1924-06-24
Abstract: 219,663. British Thomson-Houston Co., Ltd., (Assignees of Kayko, C. J.). July 24, 1923, [Convention date]. Drawings to Specification. Vacuum tubes.-A cathode is formed by mixing with a binding agent a difficultly vaporizable compound of highly electropositive metal, such as an alkali or alkaline-earth metal, and a finely-divided metal such as nickel or molybdenum or an oxide thereof which is capable of being sintered at a temperature insufficient to vaporize the compound, and forming the mixture into a filament, removing the binder, and sintering at temperatures which are too low to volatilize the compound. The compound may be an oxide or tungstate. In an example 95 parts by weight of finely divided nickel or an equivalent amount of nickel oxide are mixed with 5 to 10 parts of barium or strontium carbonate or sulphate, or sodium tungstate, together with sufficient binder to form a squirtable mass which is subsequently extruded, and the binder removed by a known process. When employing a carbonaceous binder such as nitrated cellulose the filament may be fixed at a temperature high enough to carbonize the binder, and decarbonized in an atmosphere of moist hydrogen. The sintering and other operations should be at a temperature not higher than 1700 C. so as to avoid volatilization of the active material. The cathode may consist of molybdenum containing 10 per cent of barium oxide. The filament is mounted in a bulb which is evacuated and carefully freed from water vapour by a material such as magnesium or calcium introduced for example as a film on the wall of the bulb. Details of the emissivity of the cathodes are given.

An attachment for producing percussive movements in a rotary drill comprises a spindle 13 axially movable in a housing 10 and adapted to be vibrated by co-operating cam means 25, 26, a ring 21 being arranged to cause a thrust member 20 to engage, to a greater or lesser extent, a tapering surface 19 in a thrust collar 17 in order to vary the amplitude of the percussive action. The cam means are in the form of balls 25, 26 located in a flange 23 on the shaft and in a ring 28 located in the housing. The thrust member 20 is also in the form of a ball and is moved into contact with the tapering surface 19 by means of recesses formed on the inner surface of the ring 21, the recesses being of varying depth. By rotating the ring the degree of contact between the balls 25, 26 and thereby the amount of axial movement of the shaft, is varied from zero up to a maximum. Three equispaced balls 20 may be used.

Filed: 1929-05-23
Abstract: 335,526. Franklin, C. S., and Witt, B. J. May 23, 1929. Condensers.-The oscillation circuit of a wavemeter or high-frequency generator has its condenser and/or coil so constructed that the capacity or inductance or their product remains constant in spite of temperature changes. Figs. 1 and 2 show one construction of oscillatory unit, and Fig. 3 shows its arrangement in a valve generator circuit. A cylindrical outer casing A supports a former B for the coil C at its closed end. The other end of the former B carries the fixed element D of a variable condenser, having sector-shaped electrodes D', D<2> projecting from its outer surface. The movable electrode E has inwardly-projecting sectors E<1>, E<2>, and capacity is varied by rotating the electrode E. The external connections L, M are made to arc-shaped plates X, Y which are spaced from the member D to form small capacities. An axial rod G carries an electrode H which is spaced from the end wall K of the member D, thus forming a capacity in parallel with the main condenser D. E. When the temperature rises, the increased capacity between D and E is compensated by a diminution between H and K, owing to the different expansion of the material of which the parts B, G, are composed. In order that the compensation may be effective throughout the tuning-range, the member H, K may be provided with arcuate extensions, and the rod G rotated with the movable electrode E. The casing A is heat-insulated so that temperature changes may be slow and uniform throughout. Parallel plate condensers may have their plate material and their spacing material so chosen that when the plates increase in area their spacing is suitably increased. When concentric cylinders are employed, the outer one is of material whose coefficient of expansion exceeds the inner.
