Title: Improvements in or relating to apparatus for casting
Inventor: STAMP THOMAS BLACKLEDGE
IPC: B22D45/00
Filed: 1967-04-20
Abstract: 1,219,422. Casting machines. T. B. STAMP. 26 April, 1968 [20 April, 1967], No. 19830/68. Divided out of 1,219,421. Heading B3F. An ingot casting machine has a conveyer A, comprising two parallel chains running between sprockets B, carrying a series of equidistantly spaced moulds C between guide rails D. A cooling plate is mounted under the moulds between the guide rails. Melt is stored in an electrically heated vessel E and delivered to the moulds by a valve F, G which is preferably electrically heated. The valve is controlled in dependence of the movement of the moulds on the conveyer. A rotating wheel H has a link I which moves back and forth along the guide rails on rollers J. A knuckle K attached to the link I engages each mould C successively to push it along the conveyer and rises above the next mould on its return stroke. A cam L on the wheel H operates an hydraulic servocylinder M, which is connected to a reversing cylinder N which, in turn, operates the valve gate G. The valve gate G is preferably provided with a velocity spoiler.

Abstract: 1392733 Abrasive tools; tumbling MINNESOTA MINING & MFG CO 28 April 1972 [30 April 1971] 19975/72 Heading B3D An elongated flap-bearing strip comprises a flexible, elongate support sheet 15 having adherently bonded to and covering one major surface thereof a plurality of spaced, parallel, transversely oriented islands of binder 14 each of which is adherently bonded to and holds in erect position a like oriented abrasive flap 11. The sheet 15 is in the form of a strip of fibrous material, such as drills cloth, and the flaps may consist of paper, film or cloth sheets having abrasive 13 on one surface. The binder islands may comprise epoxy resin, hide glue, phenolic resin, silicone resin, polyurethane resin or polyamide resin. The support sheet may be passed along the bottom of a trough into which the binder is poured in liquid form so as to have a thickness equal to the desired height of the islands. The flaps, with a release coating on one side or the other, are placed with their edges in the liquid binder which is then allowed to harden so as to form the islands 14. Preferably the islands are adhered to the non-abrasive sides of the flaps. Alternatively, non-adherent spacers are placed between the flaps and removed after hardening of the binder which is thus formed into islands adhering to both faces of the flap (Fig. 4, not shown). The flap-bearing strip may be formed into an endless belt or an annulus so as to provide a flap wheel, the ends of the strip being butt joined and the annulus being attached to a stretch-resistant support member 22 of glass fibre, metal mesh, polymeric fibre, or the like or, for a small wheel, a wood or chipboard core. Alternatively, the strip may be wound helically on a cylindrical support. In another embodiment, the strip is mounted so that the flaps extend radially inwardly for finishing round workpieces. In another use, the strip is mounted on the interior surface of a tumbling drum.

[Also in Division B8] Apparatus for pressing voluminous fibrous material such as wood shavings into bales and packaging the bales into bags, comprises a vertical shaft 7 the bottom of which is provided with a tubular outlet 12 opposite which is disposed a reciprocable tool 11. The end of the outlet is covered by a bag 14, of e.g., polythene. In operation, the shaft is fed with a predetermined amount of material from a side mounted box 2 having a pivotable bottom and the material is compressed to the level shown in the Figure by a vertical tool. The bale 16, thus formed, is then expelled, by tool 11, from the shaft into the outlet 12, this causing the bale 15 formed by the preceding cycle to be expelled from the outlet together with the bag on to takeoff conveyer 18. During the expulsion the bale 16 is compressed due to the resistance to movement of the bale 15 within the outlet.

Abstract: 1292363 Two part couplings COAL INDUSTRY (PATENTS) Ltd 20 April 1971 [28 April 1970] 20283/70 Heading H2E [Also in Division E2] A plug and socket connector has a means for mutual coupling, the plug and socket each having a main contact and a pilot contact, adapted so that when the plug and socket are coupled together the main contacts make contact before the pilot contacts and on disconnection the pilot contacts break connection before the main contacts, the coupling means introducing a time delay between the making of the respective contacts and between the breaking of the respective contacts. The plug 2 has four main contacts 6 and the pilot contact 10 rigidly mounted therein while the socket 4 has four main contacts 8 and the pilot contact 12 mounted resiliently on springs 66 and 78 respectively. The contacts, the socket housing 52 and the plug casing 16 are dimensioned so that when the plug and socket are coupled, the housing and casing meet first to form a flameproof enclosure, the main contacts 6, 8 then mate and finally the pilot contacts mate to energize a remote relay solenoid which supplies power to the socket main contacts. In order to provide sufficient time for the relay solenoid to operate during uncoupling, the coupling means comprises a ring 90 rotatably mounted on the socket, the ring having two pins 92 which travel in tortuous slots 94 in the plug casing 16. The connector is retained in the coupled condition by a spring catch (96) on the socket engaging a key (99) on the plug. In another embodiment (Figs. 4 to 6, not shown) the coupling means comprise pins (104) on the plug which co-operate with a pivotally mounted cam mechanism (100) on the socket. The connector is intended for a three-phase supply and the power may be reversed by uncoupling the plug 2, rotating through 180 degrees and recoupling.
