Patent GB-299830-A (GB)
Title: Improvements in or connected with toothed gearing
IPC: F16H57/02
Filed: 1927-08-02
Abstract: 299,830. Saccaggio, P. C. Aug. 2, 1927. Movements of vehicles, utilizing. - In toothed gearing for transmitting power between a railway or like vehicle axle b &c. and the shaft e of a traction motor a lighting-dynamo, air compressor, &c. wherein the motor &c. is suspended from the bogie &c. or is otherwise laterally movable, the axle and shaft are spaced by a universally jointed link l, l<1>, Fig. 1, or v, v<1>, Fig. 4, and the shaft e is connected to its gear-wheel g by a universal joint k, which may be of the kind described in Specification 297,868. The gear-wheels g, f may carry cylindrical extensions h of pitch-circle diameter, as described in Specification 297,141, to ensure correct gear meshing. The link parts l<1>, l are connected by parallel pivots p<1>, p to a sleeve n turning on the casing of the motor a and a sleeve m turning and sliding on the axle b. A collar o turns freely in a slot in the part l and is secured to the part l<1> but may be screwed along the latter to provide adjustment for different spacings of the shaft e and axle b. The link connection thus permits relative universal and axial displacements of the shaft and axle while maintaining their spacing. As shown in Fig. 4, the link parts v are mounted respectively by a ball- and socket joint upon the sliding sleeve m<1> and by a self-aligning bearing w upon the shaft e. The link parts slide axially one in the other, the motion being cushioned by rubber or like pads z. This construction thus tends to maintain gearing engagement but provides for small changes in the spacing of the axle and shaft. This provision is dispensed with in a modification in which the bearing w is replaced by a ball-and-socket joint and the cushioned connection by a rigid connection comprising thin plates or shims for adjusting the total link length.

Title: Improvements in ceramic bodies having substantial electrical conductivity
IPC: H01C17/20
Filed: 1937-07-26
Abstract: Material for electric resistors, having a resistivity between 10 and 10,000 ohms. per cm. cube, is made by heating in a non-oxidizing atmosphere a mixture of finely divided inorganic solid material, e.g. carborundum or precipitated silica and a carbonaceous binder that can be carbonized by heat, to such a temperature, not less than 1200 DEG C., that the solid particles are sintered together to a mass in which carbon is dispersed.  When carborundum is the solid material a ceramic bond is necessary, e.g. aluminium silicate, sillimanite or an aluminium silicate glass comprising for instance 45 per cent of alumina, 45 of silica, 4 of magnesia, 4 of thoria and 2 of beryllia. Suitable carbonaceous binders are starch solution and synthetic resin varnishes.  Metal powder, e.g. molybdenum may be added to the mass to form conducting material, e.g. as leads for the resistors.  In an example, 75 parts of carborundum with a grain size not exceeding 100m , are mixed with 25 parts of finely ground sillimanite, aluminium, silicate, glass, or such glass ingredients, and sufficient starch solution or synthetic resin varnish to render the mass plastic.  The resulting body is fired in dry hydrogen for 5 to 30 minutes.  The resistance may be increased by heating the fired resistor in an oxidizing atmosphere, e.g. wet hydrogen.

Title: Improvements in and relating to missiles
IPC: F42B15/00
Filed: 1963-05-23
Abstract: 990,500. Safety devices. REPUBLIC OF FRANCE, ARMY MINISTER, and NORDAVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. May 23, 1963 [Oct. 18, 1962], No. 20647/63. Heading F3A. Self-propelled missile (not shown) having a warhead, the fuze for which is armed by the pressure of the propellent gases comprises a combustion chamber 6 containing an end burning charge 1, the propellent gases being fed to an arming device through copper tubes 3 when the propellant has burnt sufficiently to expose the inlets to the tubes. The tubes 3 are embedded in heat insulating layers 2, 2a so that the hot gases within them do not ignite the adjacent propellant ahead of the normal combustion surface. By adjusting the depth of the tube ends 3b the required period of delay and corresponding distance travelled by the rocket are selected since these are proportional to the thickness of the layer of propellant to be burnt before the tube ends are exposed. Furthermore, should the propellant not become fully ignited, there will be an insufficient pressure developed to operate the pressure control. Alternative materials for the tubes are other metals and synthetic plastics.

Title: Improvements in or relating to suspension devices for vehicles
IPC: B60G5/053
Filed: 1931-07-20
Abstract: 381,976. Road vehicle suspensions. FLEXION PRODUCTS, Ltd., The Hyde, Hendon, London.-(Automotive Engineering Corporation; Southern Bank Buildings, Macon, Georgia, U.S.A.) July 20, 1931, No. 20744. [Class 108 (ii).] In vehicles in which two axles are connected by inverted equalizing springs one on each side, auxiliary resilient means are provided so as to coact with one or both axles and come into action only when the vehicle is loaded. The equalizing springs may vary the distribution of weight between the two axles when the load attains a predetermined value. One end of an equalizing spring may be connected to the driving axle through a lever formed by extending the radius or torque member. In the construction shown in Figs. 1 and 2, the driving axle 13 and the non-driving rear axle 14 support the frame 11 through inverted equalizing springs 25, 26, the centres of which are clamped to saddles 27 pivoted to the ends of a transverse shaft 28 carried by the main frame. A short spring arm 31 cooperates with the lower spring 25 to resist torque of the axle 14. When the vehicle is lightly loaded only the lower spring 25 is operative, but when the load increases, the upper spring 26 then bears on the axles as shown. The central spring 38 at the same time increases the proportion of the weight of the vehicle applied to the driving axle 13, this spring being pivoted intermediately to the transverse shaft 28, while its ends have sliding connections with a bracket 42 on the driving axle 13 and with a cross member 41 of the frame 11. In the modification shown in Fig. 6, the rear end of each equalizing spring is pivoted at 45 to a bracket 46 fixed to the rear axle. When the load increases sufficiently, the forward end of a box-like extension of the bracket bears on the upper side of the spring and varies the distribution of weight between the two axles. The central spring 53, which also varies the distribution of weight, is fixed to the central part 49 of the driving axle and shackled at 54 to the cross member 58 of the main frame. In a further modification shown in Fig. 8, the front end of each equalizing spring 84 is connected to a short rearward extension 73 of the radius or torque arm 67 of the driving axle.

Abstract: 532,456. Fabrics composed of threads united by adhesives; laminated materials; glass fibres. VERSIL, Ltd., and PALMER, S. July 21, 1939, No. 21210. [Class 140] [Also in Group XXIII] A tape or strip of glass fabric is produced by making a helical cut on a laminated sheet of fibres while it is still on the drum on which it has been formed, the sheet being composed of layers in which the fibres in one layer are at an angle to those of the adjacent layer or layers. The sheet of fibres may be formed by winding a layer 12c on a drum 4, spraying the layer with a binding medium, cutting the layer along a line parallel with the axis of the drum, and then removing the layer and attaching it to the drum again with the fibres at an angle, say, a right angle, to their former direction. A second layer is then wound on the first layer, and the laminated sheet is sprayed with a binder, the drum being heated if a baking varnish is used. A backing of paper, asbestos paper, papier mache, or textile material may be placed around the drum before the first layer of fibres is wound on. The strip or tape may be cut from the laminated sheet by making a helical cut with a cutting wheel 40 mounted on a fixed leading-screw 41 carried by spring controlled arms 42. The wheel 40 is pressed against the drum and is rotated by it, and makes a helical cut along the sheet. The tape or strip may be sprayed with or passed through a bath of baking varnish as it is wound off the drum, and then passed through a heated drying chamber.
