Title: Filter presses
IPC: B01D25/172
Filed: 1976-01-12
Abstract: In a filter press having filter plates (10) which can be individually slid by a transport element, each filter plate (10) is locked to the following filter plate by a bar (16), which is latched in a positive-fit manner by a latching element (22, 24) on the preceding filter plate (10) and is released on removal of this preceding filter plate. However, even after release of the bar (16), the filter plate (10) remains coupled to the following filter plate by a friction-fit coupling, for example by a spring (18) acting on the bar, the coupling force of this friction-fit coupling being dimensioned smaller than the tractive force of the transport element, but greater than the adhesion between the filter plates effected by the filter cake. As a result, unintentional rolling away of the filter plate after release of the bar is prevented. <IMAGE>

Title: Improvements in and relating to magneto-mechanical or electro-magneto-mechanical devices
Inventor: HARDING GEORGE NELSON
IPC: H01F7/02
Filed: 1949-01-20
Abstract: 673,649. Magnetic couplings; electromagnets. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 17, 1950 [Jan. 20, 1949], No. 1646/49. Class 35. A spirally-magnetized magnet 21 is rotated by variation of the effective axial extent of a stationary pole member 23. In the form shown, this effective variation is produced by grading the spacing of the polepiece from the magnet so that progressive increases of flux produced by the coil 23b or an adjustable permanent magnet cause the shaded portions of the poles to become saturated. Thus the mean flux position and therefore the angle of the magnet is altered. In an alternative form, the pole may be tapered or wedge-shaped and be mounted to extend and be adjustable tangentially of the cylinder to change the axial extent of the overlap between the pole and the rotating magnet. In a modification, a pair of mutually sliding wedge-shaped members may be used. The magnet may be in the form of a twisted strip instead of a cylinder as shown.

Abstract: 122,497. National Wire Manufacturing Co., Connor, R. D., and Slinger, R. P. Jan. 31, 1918. Planishing and beating.- In machines for hammering the dies used in wire-drawing machines preparatory to reforming the holes, a mechanically-operated hammer acting on the top face of the die moves to and fro in a straight path across the die, which is rotated about the axis of its hole. The die v is held by magnetic attraction, gripping-jaws, or other means in a recess in a block d rotated from the driving-shaft j by belt and bevel gearing, and is beaten from its edge to its centre and back again by an inclined pneumatic or other hammer n controlled by a valve p, and carried on a frame m supported by a link l pivoted on the bed a and by a rod u sliding in a rocking bearing u' and resting on an adjustable screw t<2> in a lever t. A cross shaft r driven by worm gearing from the shaft j carries three cams r<2>, r<3>, r<4> operating respectively a rod s adjustably secured to the link l, one end of the lever t, and a lever 2 operating the valve p. The machine is started by pulling a rod z connected to a lever z<1> on a spindle w<1> which carries the belt 1 on to the fast pulley and at the same time a second arm x on the spindle w<1> engages with one end of a trip lever y, the other adjustable end of which bears against the link l. The rod u is first lowered and brings the hammer into engagement with the edge of the work, and the link l is then moved to bring the hammer to the die centre and return it to the edge. The hammer is then lifted and the link l moves the trip lever y and releases the arm x so that a counterweight x<1> shifts the belt 1 to the loose pulley and stops the machine. As the hammer approaches the die centre, the valve p is gradually throttled to reduce the power and speed of the hammer. The action of the hammer may remain constant and the speed of the die be changed. An air jet 4 removes scale or dust.
