Title: An extrusion head having air venting means
Inventor: CAPELLE GERD
IPC: B29C48/12
Filed: 1989-12-04
Abstract: The head (1) for processing rubber or thermoplastic plastics material, is flange-mountable on a screw extrusion device (2), and comprises an inlet region receiving material from the extrusion device and the downstream end (3) of the screw, the inlet leading into a flow channel portion (4) and a nozzle outlet (8) for extrusion of the material in the form of a shaped profile. A sealable air discharge device (10, 11, 13) within the flow channel portion (4) serves to remove air bubbles, during the start up phase of the extrusion downstream of the screw end (3), and comprises an air discharge conduit (10) and channel (11), and a piston (13) which is displaceable into the conduit (10) by hydraulic or screw means, to seal it against material leakage after the air has been removed. The sealing displacement of the piston may be initiated by the pressure of material upon a sensor (21).

Title: Sorting particles
Inventor: LEVITT CHARLIE MAURICE
IPC: B07B13/00
Filed: 1991-07-05
Abstract: Particles are sorted on the basis of different thermal characteristics. The method involves wetting the particles 24, 26, e.g. diamonds and rocks, with a liquid, e.g. water, and bringing the wetted particles into contact with a surface 12 which is at a temperature lower than the freezing point of the liquid. Contact is maintained for a period of time sufficient for all the particles to be adhered to the surface by the liquid freezing. Thereafter, different classes of particles, distinguished from one another by their thermal characteristics, are independently separated from the surface, by applying heat to the particles, e.g., from a warm water bath 28 or spray. The particles may be carried on a rotary internally cooled drum and adhered to a layer of ice. <IMAGE>

Title: Parameter tolerant pll synthesizer
Inventor: HIETALA ALEXANDER W
IPC: H03L7/089
Filed: 1991-12-02
Abstract: In a PLL synthesizer, the tolerance to gain and component variations is greatly reduced when the gain of the loop is increased above that which the loop was initially designed for and if the third order loop symmetric ratio is reduced to a value within the range of 2.0 to 2.5. In a preferred embodiment, reference oscillator (601) supplies a frequency stable signal to a phase detector (603). Up and down correction pulses are applied to an up current source (105) and a down current source (107) respectively. The loop filter (609) provides a fifth order response. The filtered control signal is applied to the VCO (103) to alter and control the frequency of oscillation. The output from the VCO (103) is output to other radio circuits and to a conventional controlled frequency divider (111) for frequency reduction before being coupled to the phase detector (603).   <IMAGE>
