Patent GB-936426-A (GB)
Title: Variable ratio power transmission apparatus
Inventor: HOBBS HOWARD FREDERICK
IPC: F16H61/02
Filed: 1961-05-30
Abstract: 936,426. Change-speed control. HOBBS TRANSMISSION Ltd. May 4, 1962 [May 30, 1961], No. 19463/61. Class 80 (2). [Also in Group XXIX] Relates to a motor vehicle change speed control, such as described in Specification 738,588, wherein automatic actuation of ratio establishing friction engaging devices is controlled by a shift piston 12 loaded in one direction by a spring 50 and in the opposite direction by output speed-responsive fluid-pressure in a space 11. In such an arrangement, to prevent undesired difference between up and downshift speeds, due to shift piston friction from transverse fluid pressure, the shift piston comprises a starter piston 19 which, when pressure in the chamber 11 decreases prior to movement of the shift piston, is moved by an inner spring 24 to exhaust, and thereby reduce pressure in, the space 11, through ports 28, a groove 27, ports 26, and a bore 25, whereupon the shift piston immediately downshifts. On downshift the shift piston covers a duct to a kickdown valve (20, in Specification 738,588) thereby effecting a pressure increase and returning the starter piston to its top position. Identical up and down shift output speeds are achieved when, for a starter piston pressure area of one-quarter of the total bore area, the inner spring 24 is designed to exert between 0.5 and 0.7 pound more than one quarter of the spring load of both springs. The spring rates may be suitably proportioned so that the excess load of the inner spring is constant throughout the range of movement of the shift piston 12 to produce the effect on all shifts. However, for starter piston actuation between, say, 4th and 3rd speeds only the inner spring is suitably adjusted for excess load in the 4-3 shift piston position. By suitable arrangement of the size or form of the appropriate duct in the cylinder in which the piston 12 operates the starter piston may be made to operate only in 4-3 kickdown. In Fig. 2 (not shown), the inner spring is retained in compressed condition by a flanged rod so as to limit the shift piston positions in which the inner spring is operable.

Filed: 1929-06-25
Abstract: 335,598. British Dardelet Threadlock (D.D.G.) Corporation, Ltd. Nov. 27, 1928, [Convention date]. Locking nuts and bolts. - In screw-andnut gearing of the form in which a radially acting wedging grip or pressure results from engagement of the tops of the threads on one member with inclined or like surfaces between the threads on the mating member, there is provided, at the base or foot of such inclines, a recess increasing the latitude of radial clearance, thereby allowing greater tolerance in manufacture. As shown in Fig 2, the recesses e<1>, e<2> provide a clearance T, the top s<1>, s<2> of the threads being deformed by the pressure as the final position, Fig. 3, is reached. The wedging effect may be such that a nut permanently maintains its grip on the bolt through the parts secured thereby may, owing to wear &c., cease to fit. The top of the threads and the recesses may be dissimilarly shaped or they may be, more or less, a close fit in the initial position. The recess may be formed on one member only, the mating members being formed with a plain inclined or cylindrical surface between the threads.

Title: Switch for distributing over a plurality of conveying tracks objects which are fed in one line
IPC: B65G47/71
Filed: 1976-05-12
Abstract: 1522063 Feeding bottles from one conveyer path to a plurality of downstream paths E BAUER 12 May 1976 [12 May 1975 6 June 1975] 19590/76 Heading B8A The apparatus described in Specification 1,477,647 is modified by the provision of a transmission mechanism between the index wheel 1 (rotated by passage of the bottles), and the crank 61 which causes deflection of the pivoting bottle guides 5. In an embodiment in which the bottle guides 5 pivot to feed three downstream channels 35, 36, and 37, a gear 2 rigid with the index wheel 1, meshes with a gear 3 carrying a crank pin 44. The latter forms part of a parallel linkage including links 47 and 53, one side of the linkage being constituted by the fixed frame carrying pivots 9 and 57. A member 48 carried rigidly by the link 47 has opposite ends which engage with cam followers 55 on a disc 54. On a shaft 56 rigid with the latter, is a crank disc 58 which is connected by a link 61 with the fixed frame at 22. The shaft 56 is also rigid with a crank 23 connected to the pivot 24 of the bottle guides 5. Also rigid with the pivot 24 is a crank pivotally connected to a link 17 which is connected at its other end to members 39-42 which define pivotal entry guideways to the three downstream channels 35, 36, and 37. In operation, each deflection of the index wheel 1 by a passing bottle, causes the short crank arms of the parallel linkage to move through 180 degrees relative to the fixed member of this linkage. This causes one or other end of the members 48 to engage one of the cam followers 55 to cause the disc 54 to make one sixth of a revolution. This causes an appropriate movement of the guides 5 and of the members 39-42. In a simpler embodiment (Figs. 1 and 2, not shown), the guides 5 feed only two downstream channels.

Abstract: 1,125,850. Brazing. ELECTRO-MECHANISMS Inc. 5 May, 1966, No. 19979/66. Heading B3R. [Also in Division H1] In bonding an electrical connector to an electrical conductor on an insulating support, an opening is formed in the support, the connector is inserted in the opening with a brazing alloy having a melting point of at least 800‹ F. between the connector and conductor and the alloy is heated for less than 1 sec. to a temperature greater than 800‹ F. In making a stacked module, a number of printed circuits, each an insulating sheet with copper elements applied thereto by electro-deposition, etching &c., are stacked and laminated by heat and pressure and holes are drilled completely through the module where it is desired to connect the circuits. In each hole a connector pin comprising a copper or nickel tube, wire or rod coated with a silver brazing alloy e.g. an alloy of silver and copper with or without indium, tin or phosphorus and melting above 115‹ F., is inserted and the tungsten electrodes of an electric spot welder are pressed against the ends of the pin and a pulse of current lasting for 1/5 second is passed through the pin. The brazing metal melts and forms fillets between the pin and the conductors. The insulating base may be of fibreglass impregnated with polyurethane plastic. In a modification a tubular copper connector 40, Fig. 9, having a shoulder 43 is inserted through a hole 44 drilled in the conductor 41 and base 42 with a disk or strip 45 of brazing alloy between the shoulder and conductor 41. The lower electrode 46 is of copper and receives the connector 40 and the upper electrode 47 is of molybdenum and engages the end of the connector. Current is passed between the electrodes and the molybdenum electrode is heated and melts the brazing alloy by conduction. An alternative form of connector for connecting the conductors of stacked printed circuits comprises a copper disc 51, Fig. 10, coated with silver brazing alloy 52 on its ends and having a laterally projecting arm 54 coated with brazing alloy. The base is drilled to receive the disc and the connector applied so that the arm 54 overlies a conductor. A series of circuits provided with connectors is stacked and the top disc is engaged with one electrode and the bottom disc with the other and current is passed to braze the discs together and their arms to the conductors. The connectors may be formed of strands of copper and brazing alloy or strands of copper wrapped in brazing alloy and the conductors may be plated with brazing alloy to form a brazed or diffusion bonded joint with a bare pin, eyelet, disc &c. It is stated that a polyurethane plastic base serves as a flux.
