Title: Ultra low volume processing of and cartridge for photographic fixer solution to recover silver therefrom
IPC: C22B7/00
Filed: 1980-06-03
Abstract: A small tubular cartridge for processing of ultra low volumes of gravity flow spent photographic fixer solution to recover residual silver therefrom. The tube cartridge comprises a hollow transparent or light transmitting flexible plastic tube of synthetic resinous material such as vinyl. The transparent tube is closed by an impervious bottom end cap which is bonded or otherwise integrally secured to the lower end of the transparent tube, with a top end cap being similarly secured to the top end of the tube and providing a central axial solution outlet opening and an eccentric solution inlet opening, each opening having a downwardly directed collar. A central solution exit tube is disposed substantially coextensive and coaxially with the transparent tube and is integrally secured as by bonding at its upper end to the central axial effluent solution opening. The axial solution exit tube has a lower bevelled end to insure that fixer solution is readily received therein and discharged from the cartridge after it has been processed. A slender coil of iron window screen having a central axial hollow passageway and an outer cylindrical surface is disposed coextensive and coaxially with the transparent tube. One axially directed free edge of the coil is unsecured at the inside axial hollow passageway and a second edge at the outside of the coil is secured against displacement by a plurality of spaced staples. The bottom of the screen is closed by a force-fit end cap which is impervious, while the top is closed by a force-fit end cap which has a central opening the diameter of which is slightly less than the diameter of the solution exit conduit. One or more spacers may be provided between the top end cap and the collar of the central axial outlet opening in the top end cap of the transparent tube to insure that the lower bevel end of the solution exit tube is sufficiently elevated above the bottom of the coil of screen to accommodate unrestricted flow into the solution exit tube even after sludge accommodates in the bottom of the tube cartridge.

Relative movement between the clutch cover and pressure plate is effected against the bias of the pressure means until the levers are in an extreme position relative to the clutch cover. The rivets are then machined, preferably by a grooved grinding wheel having a suitable contour in order to adjust the nose ends of the levers to a pre-determined common plane. Alternatively, the heat treatment step may be limited to the rivet per se, wherein the rivet may be heat treated after the machining step.

Patent ES-8406236-A1 (ES)
Title: Two high hot rolling mill process and narrow strip product.
IPC: B21B39/14
Filed: 1983-10-25
Abstract: A rolling mill capable of forming a hot, continuously cast metallic strand into a strip with a large bite and with one pass per mill stand uses only two small diameter rolls per stand, each mounted for rotation in a pair of chock blocks and each having a comparatively narrow, enlarged diameter working portion. The outer surface of the working portion is profiled to maintain the product centered on the rolls and to accommodate for thermal expansion. An hydraulic motor that produces a large torque at a low rotational speed with good control rotates each roll. The motors are coupled to their associated rolls directly. A pair of hydraulic cylinders mounted on upper frame beams are each connected to one of the chock blocks of the upper roll. The upper frame and the cylinders pivot together to provide a direct overhead access to the rolls and their chock blocks for a rapid replacement of the rolls. The mill includes rotary brushes that are adjustably loaded against the working portions of the rolls to remove adhered strand material and to prevent a release agent from accumulating on the rolls. An entrance guide assembly provides a partial atmosphere control and edge rolls that to some extent steer the strand to the center of the rolls. A narrow strip with a recrystallised grain pattern and accurately controlled dimensions is produced by three such two high mills operating in tandem. The first mill produces the high reduction and sets the width of the strip. The second mill reduces the thickness further. The third mill is a finishing mill that produces a final thickness reduction.
