Patent WO-0158676-A1 (WO)
Inventor: DIONNE HUGUES
IPC: B30B9/18
Filed: 2001-01-05
Abstract: A screw press provided with a rear excess fluid outlet is described herein. The rear excess fluid outlet includes a circular screen (30) provided at a longitudinal end of the screw press body, near a material inlet. Scraper blade assemblies (34) are provided to prevent the screen (30) from clogging.

Abstract: A self-synchronizing servo control system and its associated servo data code for use in a high-density disk memory is disclosed.  The servo data is formatted into a sync/index zone and a data zone.  Sync and index di-bits are written only in the sync/index zone, while only servo data position di-bits are written in the data zone.  Elimination of the sync and code di-bits used in prior art methods removes all requirements for radial phase coherence during the writing process, and increases the servo sample frequency.  The new servo data code also reduces the intersymbol interference seen by adjacent pulses.  The associated configuration of the servo control system is also disclosed.

Title: Lockproof low level oscillator using digital components
Inventor: BROSH AMNON
IPC: G01R27/26
Filed: 1991-02-04
Abstract: ABSTRACT LOCKPROOF LOW LEVEL OSCILLATOR USING DIGITAL COMPONENTS           Three series connected inverters (38, 40, 42) are attached  to  a  tank  circuit  (18)  which  includes  an inductance (12, 14) and a capacitance (16, 17).  Negative feedback from the third inverter (42) to the first inverter (38)  biases the inverters at the midpoint between the bistable  low  and  high  logic  level  states.    Positive feedback from the second inverter (90) to the tank circuit induces oscillation in the tank circuit.   The negative feedback is decoupled at the resonant frequency and the energy delivered to the tank circuit from the positive feedback maintains a low level oscillation in the tank circuit.   Negative  feedback around the three  inverter digital circuit prevents lockup in the event of power loss or momentary short.

Abstract: METHOD FOR FORMING PLASTIC MOLDED PANELS WITH INSERTS     ABSTRACT OF THE DISCLOSURE           Plastic panels which are useful as automotive interior trim panels, interior door panels and the like decorative and structural panels, are made by a method which integrates insert sections in the surfaces of the panels and eliminates insert edge trim molding strips.  The method includes bonding at least the edge portions of the inserts upon a thin plastic sheet, pre-sized blank, then removing the plastic sheet portions that overlap the insert within the bonded portions; next, positioning the blank in a mold against a mold face and molding in situ and simultaneously bonding a plastic substrate against the blank and the exposed surface of the insert.  A substantially continuous, channel forming means, such as a narrow rib or a groove, on the mold face, is overlapped by the bonded insert edge portions and sheet portion, which are folded by said means to form a narrow, relatively deep channel.  The insert edges are part of and, consequently, are concealed within the channel.  The channel forms an edging around the insert in the completed panel surface. Thus, the composite sheet and insert forms an exposed, decorative surface on the molded plastic panel.
