Title: Radial piston fluid handling devices
IPC: F01B13/06
Filed: 1974-11-28
Abstract: 1495727 Reciprocating pumps K EICKMANN 28 Nov 1974 51658/74 Heading F1A In a radial-piston pump a rotor 9 has pistons 2 with pivoted shoes 12 that engage with a cam, or "guide", ring 33 and lie between annular plates 14 secured to either the rotor or the guide ring, the radial dimensions of the shoes being less than those of fins 23 extending circumferentially of the rotor between the cylinders 10 for the pistons. The shoes when the respective pistons are in the fully retracted position thus lie radially below the outer surfaces of the adjacent fins (as shown on the left-hand sides of Figs. 1 and 2). An annular slot 24 saves the ring 33 from being fouled by the fins. Lubricating and pressure-balancing recesses 16 and passages 21 may be formed in the shoes. Substantially hemi-spherical portions of the shoes are retained in the pistons by virtue of the matching shapes of the seats for these portions. A second embodiment, Figs. 5 and 6 (not shown), differs in that the shoes are free to move both radially and axially relative to the pistons and lubricant is fed to the shoe surfaces through narrow helical passages (63) in the pistons. A third embodiment, Fig. 7 (not shown), has two sets of pistons disposed axially side-by-side in a common rotor and radial projections (75) on the shoes extending into an annular channel (78) in the rotor. In a fourth embodiment, Figs. 8, 9 and 10 (not shown), the shoes pivot about axially-orientated axes only and can move axially between the plates 14.

Abstract: 1396973 Rolling tubular workpieces POLITECHNIKA WARSZAWSKA 16 Nov 1972 [26 Nov 1971 23 May 1972] 52870/72 Heading B3M [Also in Division B5] A tubular workpiece 1 (Fig. 1a), is rolled on to a profiled core 4 by a pair of rolling jaws 2 and 3 each of which follows a circular, but eccentric path around the workpiece axis (Figs. 1c and 1e). The jaws may have smooth or toothed working surfaces in order to form similar surfaces on the outside of the workpiece. During each rotary cycle of the jaws, they come out of contact with the workpiece and allow it to be fed axially. The working may be performed cold or warm. The core may rotate during working but not move axially (Fig. 3, not shown), or may remain stationary except for periodic axial movements (Fig. 4). In the latter case the core produces a helical thread on the interior of the workpiece, and each rotation of the workpiece by the jaws feeds it along the core to a small extent. The spring 5 returns the core to its initial position when the jaws lose contact with the workpiece.

Title: Improvements in or relating to the purification of acrylonitrile and acetonitrile
IPC: C07C/
Filed: 1965-12-22
Abstract: Acrylonitrile and acetonitrile are separated from a mixture containing the two compounds together with impurities, such as propionitrile and other higher nitriles, by submitting the mixture to fractionation in the presence of a countercurrent stream of water in a multiplate distillation column, from which an aqueous mixture containing the impurities (together with some acrylo- and aceto-nitrile) is removed from the 5th to the 15th plate below the point of introduction of the feed mixture into the column.  A vapour mixture of acrylonitrile and water is obtained at the head of the column; and an aqueous solution of acetonitrile is withdrawn from the base of the column.  The vapour mixture from the head of the column is condensed.  The condensate separates into an aqueous phase and an acrylonitrile (saturated with water) phase.  The latter may be dried to obtain pure acrylonitrile as final product.  The aqueous phase may be supplied to the top plate of the column.  The aqueous solution withdrawn from the base of the column may be concentrated by distillation to obtain the acetonitrile/water azeotrope.
