Title: Crushing apparatus
IPC: B02C4/30
Filed: 1979-12-06
Abstract: Apparatus for crushing fragments of mineral material comprises a rotary crusher mounted above, and co-operating with, a scraper-chain conveyor. The rotary crusher has a cylindrical body provided with a plurality of first, second and third rows of chisels. The chisels are detachably mounted in holders fixed to the cylindrical body. The chisels are all the same, but the holders are of different sizes so that the chisels of a first set have a longer radial reach than the chisels of second set, which in turn have a longer radial reach than the chisels of a third set. Each first row has chisels of the first and second sets, and each of the second and third rows has chisels of the third set. The provision of the chisels of the first and second sets having longer radial reaches enables the mineral material to be drawn into the crushing gap between the rotary crusher and the scraper-chain conveyor and broken up more efficiently.

Title: Process and apparatus for drying compact vitrifiable mixtures.
IPC: F26B17/14
Filed: 1980-05-27
Abstract: In apparatus and method for treating granular product within a cylindrical chamber as the product, by the force of gravity, falls through a plurality of regions maintained at varying temperature and pressure. Structure formed by at least a pair of collectors is connected tangentially to a housing surrounding the regions to withdraw gas from and reintroduce gas to the cylindrical chamber.

Title: Transistor protection circuit
IPC: H03F1/52
Filed: 1981-06-19
Abstract: A circuit is described for protecting a semiconductor junction device such as a transistor against damage from high voltage transients that can be produced by kinescope arcing in a television receiver. The protected device is coupled to a circuit point at which the transients can appear. The protection circuit comprises a normally nonconductive protection transistor with a collector coupled to a source of operating potential, a base coupled to a source of threshold conduction bias reference voltage, and an emitter connected to the circuit point at which high voltage transients are likely to appear. The base bias of the protection transistor is determinable independent of the bias of the protected device, and the protection circuit is connected to the protected device with substantially zero voltage offset between the circuit point and the protected device. The protection transistor conducts in response to transient voltages appearing at the circuit point above a threshold level, and provides a path for safely diverting potentially destructive transient current away from the protected device.
