Disclosed is an improved cutting-and-transferring system for cutting and separating a workpiece into pellets. The workpiece is held by a holder member. The system comprises: a holding table for holding a workpiece to be cut; a cutting unit including at least cutting means for cutting the workpiece on the holding table into pellets; a transferring unit including at least transferring means for picking up the pellets from the holder member and for transferring to a selected carrier tray; and a shuttle transfer unit for transferring a selected cut workpiece from the cutting unit to the transferring unit. All these parts work automatically in unison, thus reducing the length of time involved for cutting workpieces into pellets and for loading carrier trays with pellets to possible minimum.

The invention relates to apparatus and method for the treatment of recyclable materials from solid waste. The material is introduced into a pressure vessel where it is heated and shredded. Fluid jets within the vessel produce a cutting/agitating action on the waste material as it flows through the vessel.

An improved method of preparing embossed metallic flakelets for a hologram pigment improves productivity through a simpler process. A metallic foil 12 is first pressed between a cooperative pair of dies 10 having mutually complementary embossed patterns to thereby transfer to the surfaces of the metallic foil 12 the embossed pattern of the dies 10. Finally, the pulverized metallic flakelets are mixed with predetermined other ingredients to make a hologram pigment.

The present invention relates to a method and a device for crushing glass bodies, in which the glass body 18 is arranged in a microwave field 4, so that the said glass body 18 is crushed on account of the resulting thermal stresses. In addition, a local plasma 20, which results in further thermal stresses, is produced on the surface of the glass body 18. Since the glass body 18 to be crushed does not come into contact with crushing means, for example rollers or the like, the pieces of broken glass 22 cannot be contaminated by abrasion particles of the crushing means. The plasma 20 permits a rapid and economic crushing of the glass bodies.

An apparatus pulverizes material composed of wet or dry discrete objects into relatively smaller particles with shock waves created by flowing the material through a housing having alternating rotors and orifice plates. The housing includes a first end having a feed chute for introducing the material into the housing, a second end having an opening for removing the smaller particles, and internal sides meeting in corners, which extend longitudinally between the first and second ends. A rotatable shaft extends substantially along a longitudinal central axis of the housing. Rotors each include a hub coupled to the shaft for rotation therewith, a substantially polygonal-shaped rotor plate centrally fixed to the hub and having apices, and a plurality of vanes each vanes extending approximately radially inward on a side of the rotor plate from an apex. Each orifice plate extends inwardly from the internal sides of the housing to a central aperture which provides an orifice around the shaft. Circumferentially spaced members are located proximate the rotors, wherein the members extend inwardly from the corners of the housing toward the rotors.

An apparatus for disrupting cells or viruses comprises a container having a chamber for holding the cells or viruses. The chamber is defined by at least one wall having an external surface for contacting a transducer device. The transducer device has a vibrating surface for contacting the wall and for vibrating at an operating frequency and amplitude sufficient to generate pressure waves or pressure pulses in the chamber. The transducer device is coupled to the wall with a preload force sufficient to create a stress within the wall. The natural frequency of the wall, when the wall is stressed by the preload force, is equal to the operating frequency of the transducer device or differs from the operating frequency by less than 50% of the operating frequency.
