Filed: 1961-02-06
Abstract: 929,640. Extruding. SCHLOEMANN A.G. Feb. 6, 1961 [Feb. 26, 1960], No. 4343/61. Class 83 (4). In the extrusion of metals, a pack consisting of a discard 17, pressing disc 15, shell 16; extrusion skirt 14 and cleaning disc 13, is removed from the billet container 12, Fig. 4, and supported upon a stationary prism 21 and a slidable prism 31, Fig. 10, whilst the pressing disc 15 is pressed out between the two prisms by a ram 34. In one embodiment, Fig. 4, after withdrawal of the container 12, the extrused product is severed by a saw adjacent the extrusion die 47 leaving an extrusion stump 18. The pack is then expelled from the container by the press ram 11 and into a catch pan 7 having gripping jaws 9, 10, Fig. 1. This pan is carried by articulated arms 1, 6 actuated by hydraulic motors 4, 8 which transfer the pack transversely from the centre of the press, Fig. 2 (not shown) to a position beneath a severing ram 34, Fig. 1. Here the pack is supported upon the stationary prism 21 and slidable prism 31 which is mounted on a slide 30 actuated through toggle linkage 32 by a motor 29. The pack is then gripped axially between a permanent magnet 28 carried through an arm 27 by a motor 22, Fig. 1, and an abutment 23 carried by another motor 24, Fig. 3 (not shown). The axial position of the abutment is adjustable. Ram 34 is then moved downwards by motor 35 to press out the disc 15 which rolls down channels 37, 38 to a turning and lowering device 39 which transfers it to a run-off channel 40, Fig. 3 (not shown), leading to a collection point. Magnet 28 is then withdrawn to the left and the adherent cleaning disc 13 is removed therefrom by contact with rods 42 and falls into a shoot 44, Fig. 3 (not shown). The prism 31 is then withdrawn and abutment 23 moves to the right to push the extrusion residue from the prism 21 and into a shoot 46. In another embodiment, Fig. 15, the discard 17 is sheared from the extruded product directly adjacent the dies 47 by a blade 48 and the pack is then carried by a catch pan 49 into the position of Fig. 1. Specifications 910,805, 910,806 and 929,639 are referred to.

Abstract: 230,052. K³chenmeister, H. J. Feb. 28,1924, [Convention date]. Sound-boxes, arrangement of; positioning and steadying sound-boxes.-Relates to gramophones or the like of the kind having two or more soundboxes carried by separate tone-arms and acting together on one record, and consists in providing means whereby the sound-boxes are automatically advanced from the outer edge of the record towards the sound groove in such a way that the needles enter the same spiral lap of the groove simultaneously. Further, to counteract a tendency to up-and-down movement of the soundboxes as they traverse the record, the tone-arms are subjected to two opposing forces. In the construction shown, levers c, d are connected to the tone-arms a, b so as to rotate therewith, these levers having attached to them branched coils or the like e, h which pass over pulleys f, i mounted on brackets on the casing of the machine and carrying weights g, k<1>. A second weight k<2> is carried by a cord h<1>, connected to the cord h and passing over a pulley i<1>. The weights k<1>, k<2> together are rather larger than the weight g, so that the sound-boxes are normally held at the edge of the record. When beginning to play a record, the operator raises the weioht k<2> by winding an auxiliary cord h<2> over a drum o, which is rotated by gearing from a lever p. The weight g then overcomes the weight k<1>, and the tone-arms are advanced simultaneously so as to bring the needles into the same spiral lap of the sound groove. Beforo starting, the proper initial positions of the needles may be determined by placing them against an adjustable strip or border fixed to the casing and projecting over the record.

Title: Improvements relating to door closing devices
IPC: E05F3/08
Filed: 1932-02-22
Abstract: 390,928. Door closing and check devices. BENTON & STONE, Ltd. and MILNER, C. E., Bracebridge Street, Birmingham. Feb. 22, 1932, No. 5185. [Class 65 (i).] In a spring-closing and fluid check device for doors, of the kind in which a helical torsion spring contained in a cylindrical barrel is associated with a check piston, sliding inside the barrel, by means of a rotary helical member slidably engaging the piston so that rotation of the spring and the helical member on movement of the door causes the piston to slide in the barrel, the piston and a guide therefor are arranged to allow the piston to rotate in the cylinder after it has moved a sufficient distance longitudinally during the opening of the door ; this arrangement allows relatively rapid movement of the door during the first part of its closing. and reduces the length of the barrel required to accommodate the piston travel. During the checking period the check fluid escapes between the piston and its guide, which may be shaped to provide a variable byepass. In the arrangement shown, the spring b is attached at its upper end to the cylindrical barrel a and at its lower end to a spindle c which rotates in a bearing in the top of the barrel a and is rotated by a lever connected to the door. Attached to the lower end of the spindle c is a helical strip e which slidably engages a corresponding aperture in the piston d ; a valve j also slides on the strip e and is adapted to engage a seat d<1> on the piston, being prevented from complete detachment by a wire support k. The piston has a groove h engaging a guide g on the cylinder wall, and the lower end of the groove opens into a gap i, Fig. 3, which allows the piston to rotate with the helical strip e after it has risen in the cylinder sufficiently to bring the groove h clear of the guide g. During the closing of the door, therefore, the piston first rotates to the position shown in Fig. 3 and then descends in the cylinder, being prevented from rotation by the guide g. The motion of the piston is checked by the valve j closing so that fluid can only escape between the walls of the groove h in the piston and the guide g ; the groove and guide may be shaped to give a variable byepass passage. The checking action is reduced at the end of the closing movement by a slot l in the lower part of the helical strip e permitting fluid to escape through the passage in the piston, so that latching of the door is ensured.
