Title: Improvements in speed governing apparatus
IPC: F02D1/00
Filed: 1934-10-20
Abstract: 444,710. Speed governors. HERCULES MOTORS CORPORATION, 201, 11th Street, Southeast, Canton, Ohio, U.S.A. Oct. 20, 1934, No. 30134. Convention date, July 3. [Class 57] A speed governor device for an internalcombustion engine comprises a centrifugal governor driven through gearing 28, 33 from the shaft 12 of the fuel injection pump and consists in weights 36 integral with arms having projections 38 engaging a sleeve 41 and projections 39 engaging a boss to limit the outward movement of the weights. A collar 43 is mounted on the sleeve 41 and pins on a ring-shaped lever 48 engage a groove 52 in the collar. The lever 48 surrounds the shaft 29 and is pivoted on an eccentric 45 which may turn about an axis 99. An upper corner of the lever 48 is connected by a link 55, adjustable in length, to a rod 20 which controls the output of the fuel injection pump. The lever 48 is loaded by an adjustable spring 70 which controls the idling speed. Secured to the governor casing is a housing 78 containing a spring 94 which abuts a disc 91 having a flange 92 engaging a flange 74 on the housing. The other end of the spring 94 abuts a member 86 which has tongues 86-1 engaging grooves 77-1 on the housing. The member 86 has a threaded extension 83 co-operating with a sleeve 81 which has teeth upon its circumference so that it may be rotated by a worm 89 to adjust the spring 94. The eccentric is journalled in the governor casing and has a sleeve mounted at one end provided with teeth engaged by a worm secured in the lever 68-2 so that the lever may be adjusted relatively to the eccentric. When the engine is under load the collar 43 engages the disc 91 and movement of the lever 68-2 causes through lever 48 movement of the rod 20. When the speed increases above a predetermined limit the governor overcomes the spring 94 to reduce the fuel. In a modification the spring 94 engages an abutment resting against a collar 134 on the housing and a second weaker spring is arranged between this abutment and the disc 91. Mounted on the other end of the eccentric is a member 119 which is adjustable relatively to the eccentric by a worm 121. The member 119 carries a projection 124 engaged by a detent 125 which limits the movement of the eccentric to reduce the fuel to maintain idle running. To stop the engine the detent is lifted when the eccentric may be moved farther to stop the fuel delivery. Specification 392,345 is referred to.

Title: Passage structure
IPC: H01G9/042
Filed: 1966-07-06
Abstract: 1,142,568. Making wire. BRUNSWICK CORP. 6 July, 1966 [12 July, 1965], No. 30279/66. Heading B3A. [Also in Divisions C7 and H1] A body, e.g. a metal body suitable for use as an electrolytic capacitor anode has its surface area increased by the provision of substantially rectilinear through passages each having a maximum cross-section dimension of under 10 mils and a length to maximum cross-section dimension ratio of over 10. The metal may be tantalum, aluminium, niobium, titanium, hafnium, vanadium, zirconium, stainless steel, iron, nickel or tungsten, uses other than in capacitors being envisaged. To form the body, a bundle of hexagonal cross-sectional wires 14 each sheathed by metal tubes 15 is supported within a can 17 by spacers 15a (Fig. 3a) and the assembly is constricted to reduce its cross-sectional diameter by rolling, extruding and/or drawing and form a body comprising the now elongated wires 14 embedded in a matrix of the metal which formed tubes 15. The material of the wires 14 is now removed, suitably after cutting the constricted body into short lengths, using, e.g. an acid which does not attack the matrix metal. The body thus formed has ninety-one through passages, but bodies having a larger number of passages may be formed by bundling lengths of the originally constricted body as shown in Fig. 9 and carrying out the constricting processes again. Preferably the material of can 17 is first removed. Preferably the passages occupy more than 9% of the cross-sectional area, are spaced apart less than 10 microns and have a variation of cross-section along their length and from passage to passage of less than 10%. The cross-sectional dimension of the passages may be less than 2 microns. For use in electrolytic capacitors (Fig. 1, not shown) the body has an anodic oxide film formed by conventional methods, and the electrolyte may be liquid or solid, e.g. manganese dioxide formed by pyrolysis in situ of manganese nitrate.

Adjoining cupping and wall ironing dies may be used, Fig. 1b (not shown), or a composite cupping and ironing die (60, Fig. 1c), of the work may be an open-ended tube (Fig. 1d) drawn through the die by a punch-mandrel. Aluminium or steel cans and shell bodies for ammunition may be formed with reductions of 85-90% in a single pass. A large portion or the entire drawing force P may be transmitted by the punch to the work in zone II so as to reduce or eliminate the transmission of force by the end of the punch. The desired "m" values may be obtained in part by limiting or omitting lubrication at the punch and more intensively lubricating the area passing through the die and/or by having a rougher surface on the punch than in the die. Strippers.-The punch may include an outer sleeve on a tapering surface which is expanded slightly on forward strokes, by liquid or an elastomer in the interior of the punch, and contracted on reversals. Lubrication.-A formula is included which relates the viscosity and thickness of a film of lubricant at the die to the velocity necessary for hydrodynamic lubrication.
