Title: Process for the preparation of olefine oxides
Inventor: KRONIG WALTER
IPC: C25B3/23
Filed: 1966-03-03
Abstract: In the manufacture of olefine oxides by passing in an olefine adjacent an anode immersed in an electrolyte containing an alkaline halide and conveying the product electrolyte through a diaphragm to the cathode, where the halo-hydain formed in the anolyte is converted to the oxide, the diaphragm consists of a mesh of polyacrylonitrile fibre.  The mesh may be spun yarn, staple fibre or other form of the polymer and is preferably shrunk by heating and then swelled in an organic solvent before use.  It is mounted in contact with a wire mesh cathode.  The anode may be porous graphite or Pt-plated Ti when a ceramic frit is used to admit the olefine to the anolyte which is preferably NaCl or KCl solution.  In examples, gaseous mono-defines, i.e. up to butylene or their halogenated derivatives e.g. allyl chloride is injected into a porous graphite anode at 25 1. per hour, and the anolyte fed through the cathode diaphragm at 21. per hour. The electrolyte is 3 to 15% solution of salt.  20% of the olefine is converted into the oxide plus small amounts of other products (specified). Electrolysis conditions are, 3 to 5 V, 20 to 90 DEG  C., C.D. 2 to 5 A.S.Dn of electrode surface.

Filed: 1930-03-25
Abstract: A copper phosphorus alloy particularly for use as a solder contains more than 2,5 but less than 6 per cent of phosphorus. In making the alloy phosphorus, or preferably phosphor copper containing about 15 per cent of phosphorus, may be added to molten copper.  Ductile strips are formed by repeatedly rolling the alloy preferably in the form of cast ingots 0,25-1 inch thick between 350 and 650 DEG  C. to a thickness of 0,04 to 0,021 of an inch followed by cold rolling to a thickness of 0,015 to 0,010 of an inch.  The solder may be applied without a flux when brazing copper, brass or bronze to copper.  For brazing copper silicon alloys or other copper alloys the joint should be cleaned with emery cloth and covered with a flux such as microcosmic salt or borax.

Title: Improvements in tensioning devices for transmission chains and the like
IPC: F16H7/08
Filed: 1926-04-12
Abstract: 273,823. Weller, J. April 12, 1926. Tension arrangements. - In tensioning-devices for driving- chains and the like, a curved spring metal or like strip, such as G or L, Fig. 1, bears against the chain between the sprockets and is stressed automatically by a spring, weight, &c. or manually by screw means &c. tending to cause the ends of the strip to approach each other and thus the strip centre to flex, the force exerted on the chain increasing with the flexing. One end of each strip G, L, Fig. 1, is pivoted to a pin H secured in the casing F, to which pin is connected a spring J connected to a pin H<1> on the other end of the strip G and a pair of springs L<3> connected to a pin H<2> on the other end of the strip L. The pins H<1>, H<2> may bear on an inclined plate K and on the casing F, respectively, to modify the action of the strips during their flexure. Both ends of a strip may be movable. A weight may replace the stressing-spring. In the form shown in Fig. 4 the compression spring R<5> acts upon the movable end of the strip Q through a rod R<2>, the end R<6> of which forms the piston of an oil-filled dash-pot R<4>, so that violent movements of the strip due to changes of chain tension are prevented. In a modification, the dash-pot piston is connected directly to the strip end and the spring acts in tension. Fig. 6 shows chains T, X tensioned by strips Y, the free end of which carry sleeves Y<3> engaging manually adjustable screws Y<4>.

Title: Hydrostatic transmission
IPC: F16H61/4017
Filed: 1970-03-02
Abstract: 1281101 Hydrostatic transmission; valves EATON CORP 2 March 1970 [28 Feb 1969] 9834/70 Headings F2C and F2V In a hydrostatic transmission wherein positive displacement pump and motor units 12, 14 are connected by a closed working circuit 24, 26 and a pump 44 supplies make-up liquid through a line 50 and one-way valves 52, 54 to the working circuit, each valve 52, 54 is arranged to open when the pressure in its associated working circuit line 24 or 26 falls below the pressure in the make-up line 50 for a predetermined time. The valves thus prevent make-up fluid being supplied to the working circuit high pressure line during a transient pressure drop and facilitate smooth running during low speed low torque conditions. Each valve comprises a ball 68 slidable in smaller and larger diameter bores 94, 102 of a valve body 64. When the pressure in the working circuit line 24 exceeds the pressure in the make-up line 50, the ball 68 is held against a conical valve seat 74. When the pressure in the make-up line 50 exceeds that in the working circuit line 24, the ball 68 initially slides along the smaller diameter bore 94 without connecting the make-up line to the working circuit line. If the pressure in the make-up line exceeds that in the working circuit line 24 for a period that exceeds the time taken for the ball 68 to travel along the smaller bore 94, the ball 68 passes into the larger bore 102 to interconnect the make-up and working circuit lines. During a transient pressure drop in the working circuit line 24, the ball 68 initially slides along the smaller diameter bore 94 without interconnecting the make-up and working circuit lines and when the pressure in the line 24 rises again the ball 68 is returned to the position shown. During the transient pressure drop the valve acts as an accumulator supplying liquid from the chamber 84 to the working circuit line 24 when the pressure drops and receiving liquid from the line 24 when the pressure rises. As shown, the hydrostatic transmission comprises a variable displacement ball type radial piston pump supplying a fixed displacement ball type radial piston motor. In Fig. 5 (not shown), the ball valves 68 are replaced by slide valve and the two valve elements are interconnected by a rod.

Abstract: In a transmitting system for a small-sized vehicle in which a crankshaft (2) of an engine (E) and an input shaft (10) of a multi-stage transmission (M) are connected to each other through a fluid transmitting device (T), a shifting clutch (Cc) is interposed between the crankshaft (2) of the engine and the multi-stage transmission in a series relation to the fluid transmitting device. A lock-up clutch (Lc) is interposed between a pump impeller and a turbine impeller of the fluid transmitting device (T). Thus, when the multi-stage transmission (M) is to be shifted, the shifting operation can be conducted lightly, in spite of a creep phenomenon of the fluid transmitting device (T), by bringing the shifting clutch (Cc) into an OFF state. Moreover, during cruising of the vehicle, the slipping of the fluid transmitting device (T) can be inhibited by the OFF state of the lock-up clutch (Lc) to enhance the transmitting efficiency.
