Abstract:
The medical waste disposer has a frame and a receiving chamber connected with the frame. The receiving chamber has a discharge port and an anvil is connected with the receiving chamber adjacent the discharge port. The anvil has an anvil aperture extending through the anvil and aligned with the discharge port. A knife abuts and slides against the anvil along an axis. A knife hole extends through the knife. An assembly plate abuts the knife in sliding engagement to sandwich the knife between the anvil and the assembly plate. The assembly plate also has an opening extending through the plate. A drive is operatively connected with the knife to slide the knife. The knife slides between a first position in which the knife hole overlaps the anvil aperture and a second in which the knife hole is offset from the anvil aperture and overlaps the assembly plate opening. Each of the knife and the assembly plate may have a second hole or opening, spaced along the axis from the first hole or opening. Further, multiple knives and assembly plates may be stacked one upon the other to provide repeated, sequential cutting. The thickness of each knife may be sized progressively thinner to provide smaller cuttings and a desired mutilation of the waste being disposed.
Abstract:
An apparatus and method for breaking down compressed bales of may or similar materials. The apparatus utilizes a canted bed mounted on wheels for movement as a trailer and a single blade knife spans the width of the bed between two cantilever mounted levers. The knife is activated by a pair of hydraulic cylinders to cut the bale into slices of widths controlled by an operator who advances the bales under the knife by controlling movement of a bale pusher actuated by a third hydraulic cylinder, with all three cylinders exchanging hydraulic oil under pressure with an external source, such as a farm tractor, through a control box. In operation bales are loaded into the lower end of the canted bed, advanced for cutting in the plane of the knife stroke by the hydraulic powered bale pusher, sliced transversely to the compressed layers by the hydraulic powered knife and discharged from a chute at the elevated end of the canted bed.
Abstract:
A runner structure composed of a runner and a sprue is discharged from an injection molding machine into a chopping apparatus having a first cutter mechanism and a second cutter mechanism. The runner structure is guided by a guide mechanism in the chopping apparatus toward the first and second cutter mechanisms. The sprue is cut off from the runner by the first cutter mechanism, and then the runner and the sprue are chopped by the second cutter mechanism. The first cutter mechanism has a lower cutter for stopping the runner structure by engagement with the sprue, and an upper cutter movable into coaction with the lower cutter for cutting off the sprue. The second cutter mechanism includes a feed roller for feeding the runner intermittently and a cutter reciprocably movable for chopping the runner on the feed roller. The chopped pieces are discharged through a hopper and delivered into the injection molding machine for recycling.
Abstract:
An apparatus for breaking heterogeneous material, in particular city solid wastes which are conveyed on a endless belt conveyor (27) which passes underneath the apparatus comprising a plurality of substantially parallel and ordinately closely juxtaposed to each other blades (15) and counterblades (8), this breaking system being supported by a guiding articulated quadrilateral rod system (13, 14, 18) adapted in unison and in sequence to open and raise to close counterblades (8) under the control of hydraulic cylinders (10), while a second auxiliary system (4, 25, 37, 40) provides to raise the first system at the end of the work stroke and to lower it again just before the beginning of its working stroke.
Abstract:
An apparatus and method for producing deuterium targets or pellets of 25.mu. to 75.mu. diameter. The pellets are sliced from a continuously spun solid deuterium thread at a rate of up to 10 pellets/second. The pellets after being sliced from the continuous thread of deuterium are collimated and directed to a point of use, such as a laser activated combustion or explosion chamber wherein the pellets are imploded by laser energy or laser produced target plasmas for neutral beam injection.
Abstract:
In handling solid urban wastes collected in plastic and/or paper bags, the bags are lacerated for exposing the waste material within them. The materials are processed to recover paper-pulp and stockfeed. In processing the material to recover stockfeed, the material is washed and separated into heavy inert components and light inert components and edible components. These lighter components are dried, loosened and passed through cyclone separators and screened to separate the edible components from the light inert components.
Abstract:
In a hydraulic scrap shearing machine having scrap shears at one end of an open feed channel which is wider than the mouth of the shears and which has one of its opposite side walls movable towards the other to squash scrap placed in the feed channel to a final width which will allow the scrap to be pushed by a feeder ram along the feed channel and into the mouth of the shears, the movable side wall is formed by the working faces of a main hydraulic ram and an auxiliary hydraulic ram which can be advanced independently of the main ram, the working face of the auxiliary ram being situated adjacent the mouth of the shears and being shorter than the working face of the main ram measured in the direction of the feed channel. Normally the main and auxiliary hydraulic rams are operated so that their working faces, together forming the whole of the movable side wall, are advanced and retracted together. However, if this operation fails to squash sufficiently the scrap in the feed channel, the auxiliary ram is operated so that its working face advances relative to the face of the main ram to squash further the scrap in the region adjacent the mouth of the scrap shears.
Abstract:
An improved apparatus particularly for grinding or chopping food products, such as meat, coffee and the like. The apparatus includes a vertically extending receptacle open at its upper end for permitting material to be deposited therein. A rotatable knife assembly is disposed within the receptacle and cooperates with a replaceable control ring which surrounds the knife assembly for defining a narrow annular flow passage therebetween. The width of the flow passage can be varied by using different control rings to permit variation in the size of the ground or crushed material. The knife assembly has pushing blades extending downwardly therefrom for permitting the crushed material to be pushed into a discharge chute. In a variation of the invention, a double knife assembly can be utilized for permitting grinding or chopping in two separate stages.
