Abstract: A developing device in which, after a film onto which an image was exposed has been heat-development processed, an image reader reads image information from the film and the image information is recorded onto a floppy disk. Then the film from which the image information was read is transported to a cutting apparatus. At the cutting apparatus, the film is grippedly transported between a cutter roller and a rubber roller and the film is destroyed such that the image information thereon cannot be read. The cutting apparatus is built into the interior of the developing device. Thus, when the film is ejected to an eject tray provided outside the developing device, the image information is already in an indecipherable state. Hence, the confidentiality of the recorded image information is reliably assured.

Abstract: An in-line grinder has been developed which can be configured to perform in a variety of applications through the use of an adjustable rotor/stator assembly, removable shear bar, and a variety of interchangeable stator-rotor configurations. A unique drive system utilizing a mechanical seal cartridge provides maximum sealing with a minimum of shaft deflection and run-out, thereby improving performance.

It has been demonstrated that a class of in-line grinders such as that described herein is applicable for sizing drill cuttings for injection into a subsurface formation by way of an annular space formed in a wellbore. The cuttings are removed from the drilling fluid, conveyed to a shearing and grinding system that converts the cuttings into a viscous slurry with the addition of water and viscosity enhancing polymers.

Abstract: A materials grinder includes a rotary grinding drum and a shear bar cooperating with the grinding drum to grind various types of materials. The shear bar is mounted on a pivotal structure adjacent the materials grinding drum. A displaceable biasing member biases the pivotal structure toward the grinding drum to maintain the shear bars in close cooperating relationship therewith. If ungrindable materials are encountered, the pivotal structure pivots away from the grinding drum against the bias force of the biasing member to permit the ungrindable materials to pass between the grinding drum and the shear bar. Once the ungrindable materials pass, the biasing member moves the pivotal structure back toward the grinding drum. Materials to be ground are fed to the grinding drum by means of an infeed conveyor and an overhead infeed roller.

Abstract: A portable recycle crusher system has a hopper with inward and downward sloping sides, and fold-out hopper extensions. A belt feeder beneath the hopper slides on a slide deck made of a low friction, wear-resistant plastic bolted to a steel plate to prevent tearing of the belt when sharp pointed objects are dumped into the hopper.

Materials fall off the end of the belt feeder onto vibrating screen, which allows fine materials to bypass a crusher. The materials then enter a large rectangular opening of the crusher, and approach rotating hammers at a proper angle and speed. The hammers strike and break the materials and throw them against abrasion-resistant plates. The broken materials fall between the spinning hammers and through sizing screen steel grates, which provide positive product size control.

Abstract: For controlling the material feed to a roller press, a method is described, whereby the difference between the operating values of a roller press before and after a forced change in the material feed is used to establish whether the material feed should be increased, reduced or maintained unchanged in order to optimize the operation of the roller press. By this method it is obtained that the roller press, regardless of the homogeneity of the feed material, will constantly be operating within the transition range between starve and shaft feeding and that, consequently, the roller press can be utilized to optimum extent, while simultaneously avoiding the fluidization problems associated with shaft feeding.

Accordingly, a deposit layer of the feed material formed on the inner surface of the liner can soon be autonomously removed by the deformation of the liner without interruption of the operation of the roller mill. Thus, stable and efficient pulverization can be continuously performed.
