Patent GB-242589-A (GB)
Title: Improvements in and relating to the manufacture of packing rings for pistons and stuffing boxes
IPC: F16J9/00
Filed: 1925-05-28
Abstract: 242,589. Schneider, K. Nov. 8, 1924, [Convention date]. Piston packing.-A split packing ring is made with an excess tension tending to expand the ring, the wearing surface being then treated by hammering or rolling to stretch the metal and thus produce a tension to counteract the excess of tension. As the treated surface wears away, counteracting tension is reduced and the initial excess tension then compensates for the reduction in the radial thickness of the ring. The excess tension may be the inherent tension of the ring alone, or the surface opposite to the wearing surface may also be treated to stretch the metal. In the case) of horizontal engines the treatment may be applied principally to those parts of the rings most subject to wear.

Title: Improvements in Hydraulic Presses for Extruding Metallic Tubes and the like.
IPC: B21C23/21
Filed: 1918-09-02
Abstract: 131,181. Extruded Metals Co., and Ruchholtz, E. C. H. Sept. 2, 1918. Squirting.-A metal extrusion press of the kind described in Specification 1501*/04, in which the mandrel is provided with a stem k which passes through the main hydraulic plunger and is operated independently to pierce the billet by a second plunger o, is constructed so that the mandrel rcd k and an integral rod n can move forwards independently of the piston o, and the wear and tear of the mandrel by friction is thus reduced. The plunger o is integral with a sleeve 1 which normally presses the mandrel forwards by acting on collars 9 fixed to the rod n. The sleeve 1 is attached to a carriage 2 which slides over a rail track 3, and a spring 7, which acts on a hollow piston-rod 5 attached to the rod n, keeps the collars 9 normally in contact with the sleeve 1. When however, the mandrel has pierced the billet and the tube is being extruded, the mandrel is substantiallv stationary, but can yield against the action of spring 7. This movement is limited by the movement of a piston 6 in an apertured cylinder 4, and in some cases the cushioning of the air limits the forward motion of the piston 4 and consequently of the mandrel.

Abstract: 1,012,853. Rolling. LOEWY ENGINEERING CO. Ltd. April 2, 1964 [April 10, 1963], No. 14304/63. Addition to 955,164. Heading B3M. In an improved rolling mill of the kind described in the parent Specification, the housings 10 are prestressed by cylinders 13 which are slidable relative to fixed hydraulic rams 14 to urge rods 27, and hence the upper chocks 20, upwardly. The rods 27 pass through bores in the lower chocks 29. A further ram 18, slidable in each cylinder 13, urges the chock 19 upwardly to set the roll pass. The prestressing force is maintained a fixed amount greater than the rolling force by means of load cells 26, whose outputs activate a servomotor 29 and valve 30 to vary the prestressing force in cylinder 13. The load on the rods 27 and thus the roll pass is thereby kept constant. The pressure in cylinder 17 is adjustable by a motor driven screw 33 on which is mounted a ram 32. The hydraulic rams may be situated at the head of the housing, and-the prestressing and roll pass adjustment rams may be at opposite ends of the housing. The supporting rolls may be dispensed with, the working rolls then being mounted in the chocks 19 and 20.
