Abstract: 1,115,009. Hammer mills. A. FOURCADE. 15 Nov., 1965 [13 Nov., 1964], No. 48476/65. Heading B2A. A hammer mill is provided with pneumatic forced circulation and has three air intakes along the path followed by the material to be ground, the first intake, which is in a feed hopper 1, Fig. 1, ensuring a constant admission of air and the other two 23, Fig. 3, and 27, Fig. 4, acting in succession to admit extra air in proportion to the extra suction set up in the circuit, when the flow of material through the device is slowed down below a predetermined level. The extra air intakes are controlled by automatically-operated, adjustable shutters 24, Fig. 3, and 28 so arranged that the downstream valve 28 opens only when the upstream valve 24 is almost entirely open. The hammers of the mill are somewhat triangular, the base 7, Fig. 2, of the triangle being curved and the two sides 8 having in the neighbourhood of the base a concavity giving the ends of the base a pointed shape. This facilitates penetration of the hammer into the material.

IPC: C25B3/29
Filed: 1964-12-07
Abstract: Unsaturated a , b -nitriles e.g. acrylonitrile is hydrodimerized to form adiponitrile in the presence mercury/alkali metal amalgam, electrolytically using an alkali solution containing acrylonitrile and an organic cationic agent, and preferably maintaining pH in the range 6 to 11 by adding alkali salts of poly-basic acids e.g. sodium borate, phosphate, or carbonate.  The cationic agent may be a quaternary ammonium or phosphonium salt or base or a tertiary sulphonium compound e.g. tetraethyl-ammonium-p-toluene sulphonate, tetraethyl ammonium iodide or phosphate, or cetyl trimethyl ammonium bromide.  In examples, an apparatus as described in Specification 1,076,783 is used in which a cylindrical vessel closed at the base by a glass fibre screw and containing a mercury layer is immersed in the alkaline electrolyte which contains acrylonitrile, or methacrylonitrile, and the cationic agent.  A platinum wire cathode dips into the mercury, and a nickel strip in the alkaline anolyte as anode.  A phosphate was added to bring pH to 7, and Co2 is bubbled through the anolyte.  Temperature is maintained at 25 DEG  to 35 DEG C. and a current of 10 amps is applied. After 30 mins., the adiponitrile extracted from the anolyte by distillation, solvent extraction &c. provided a 65% yield. Reference is made to reducing the product to hexamethylene diamine, forming the adipate and condensing to the polymer, all chemical processes.

Title: Apparatus for inverting a sheet moving in a first direction and causing said inverted sheet to move in a second direction

Abstract: 1487954 Inverting sheets XEROX CORP 20 Nov 1974 [28 Dec 1973] 50283/74 Heading B8R A sheet S is inverted by moving a guide 32 into the path of the sheet so that the sheet is deflected around roller 34 and is brought into abutment with resilient stop 44 between guides 46 and 48 and then moving the sheet away from the stop by means of rollers 36 and 50. The described apparatus may be incorporated into a copying machine such that a sheet printed on one side is deflected by guide 32 into the space between guides 46 and 48 and is forwarded past stop 44 (which is in the retracted position, Fig. 3) to a sheet stacker. The sheet is then separated from the stacker, printed on the other side, deflected by guide 32 to a position against stop 44 and then fed out by rollers 36 and 50 to a collator. If guide 32 is kept in the retracted position sheets pass directly to the collator. Movement of stop 44 to its aperture position moves guides 46 and 48 apart and thus separates rollers 38 and 40 to permit reverse movement of the sheet.

A fuel-injection pump for delivering a primary injection and a secondary injection to a compression ignition engine during each working cycle, comprises a piston 10 with annular grooves 11 and 12 communicating with the working chamber of the pump and co-operating with the working chamber inlet port 14 to determine the end of each injection, the piston being reciprocated by a twolobed cam which is shaped such that, after the primary injection, the piston is moved back on part of its return stroke and is then moved forward to perform the secondary injection. The piston is moved back so that it can gain sufficient speed for efficient actuation of the injector by the secondary injection. The primary injection cam lobe LMN has a smaller lift than the secondary injection lobe PSK, the lobes being joined by concentric portions KL, PN of different radii. Cam portion SK, LM, MN and PS are substantially rectilinear.
