A screening apparatus (10) for screening particulate material includes a frame (12) having an open bottom (14) through which screened particles can pass and a plurality of banks of blades (16A 16E) supported on the frame (12). Each bank of blades (16) is rotatable about respect axes of rotation (18A 18E). The blades (20) of each bank (16) are evenly spaced and arranged in a single row coincident with their respective axes of rotation (18). At least one of the banks of blades (16) is able to slid...

A paper shredder includes a shred container having an open end formed with two opposite pivot seats, and a shredder cover provided with two pivot members at two opposite sides thereof. The pivot members are mounted on the pivot seats of the shred container such that the shredder cover is turnable about the axes of the pivot members.

A blade for food processors is provided on at least one surface with a plurality of spaced cutting teeth, which are slantingly or perpendicularly projected from the surface of the blade. Each of the cutting teeth includes a substantially pyramidal projection and a substantially triangular shallow recess located in front of the pyramidal projection. When the blade is mounted in mixer, juicer, or other types of food processors, the cutting teeth cooperate with serrated edges of the blade to very q...

A comminuting apparatus is provided with a housing, at least two intermeshing scissor rolls, a screen, and an access tray. The housing has an entrance opening for receiving waste material and an exit opening for removing subdivided waste material. The scissor rolls are carried within the housing between the entrance opening and the exit opening for subdividing the waste material. The screen is carried by the housing between the scissor rolls and the exit opening. The access tray is provided by t...

An isolated polynucleotide at least 60% homologous to SEQ ID NO: 1, 3, 5 or 18 encoding a SARP polypeptide; vectors comprising a polynucleotide sequence encoding at least 11 consecutive amino acids of .alpha.SARP polypeptide; a host cell transformed with an isolated polynucleotide or vector; antibodies specific for SARP and use of such polynucleotides and antibodies in diagnostic and therapeutic method. Therapeutic uses of antibodies and polynucleotides of sarp. Methods for treating diseases rel...

A locking system for an appliance has lid and feed chute locking components that include a spring-biased, ramp surfaced pivoting arm that is adapted to be activated to extend or retract a rod that activates or de-activates a motor drive of a food processor. The arm is activated by rotational movement of the lid relative to the bowl, as an extension member attached to the lid, which is activated by insertion of the plunger, extends downwardly from the lid and engages the ramp surface of the pivot...

A vehicle has a housing mounting within it a rotor assembly comprising parallel shafts having intermeshing cutter discs in axially spaced relation thereon. The discs have radial projections with first cutting edges extending axially to face in a rotatively leading direction. Cutter segments carried on the discs project radially outwardly to provide second cutting edges of lesser axial extent facing in the leading direction. A toothed member mechanism carries teeth which project into the axial sp...

The present invention relates to a round undulating blade for shredder, where a sheet metal is integrally formed into a round undulating blade to serve as the blades for constructing a blade module. The blade includes: a periphery; an undulating blade flank including at least two cambers having a first curvature and at least two cambers having a second curvature alternatively arranged with respect to the cambers having the first curvature; and hooked edges formed on the periphery of the cambers ...

Disclosed is a shredder blade made by punching and bending that is integrally made by punching a metal sheet having a thickness of about 0.6 mm by a punching die to form a circular blade body, where the circular blade is formed into a serrated cutting edge around it periphery, and symmetrical cutting portions, connecting portions and supports extending outwards from a top and a bottom transections of the blade body, wherein the cutting portions, connecting portions and supports are first pressed...

The invention relates to a multi-roller crusher for the comminuting of mineral mill-feed, whereby the crushing roll are provided with crushing teeth, extending in the circumferential and longitudinal axial directions. Viewed in plan, the crushing teeth are arranged on each crushing roller such that several serial crushing teeth groups are formed behind each other, the imagined connection lines of which run successively at an inclined angle to the plan (1',2') of each crushing roller outer edge i...
