Abstract: ABSTRACT OF THE DISCLOSURE         A paging receiver includes a receiving section for receiving a paging signal which includes a preamble signal, a synchronization codeword and an address codeword.  A switch controls power supply to the receiving section in response to a control signal. The preamble signal is detected to produce a preamble detect signal, the synchronization codeword is detected to produce a synchronization codeword detect pulse and, the address codeword is detected to produce an address codeword detect pulse. An error detector detects an error in the address codeword and produces an error detect pulse when the number of errors detected is greater than a predetermined value.  A controller, in a waiting mode, generates the control signal intermittently at a predetermined interval, generates the control signal continuously for a predetermined duration when the preamble detect pulse is received during the intermittent gen-eration of the control signal, generates the control signal at a predetermined timing when the synchronization codeword detect pulse is received during the continuous generation of the control signal and generates the control signal at the predetermined interval when the error detect pulse is received during the generation of the control signal at the predetermined timing.  The generated control signal is applied to the switch.          Improved battery saving efficiency is achieved.

Title: Filter
Inventor: YOUNGER GILBERT W
IPC: B01D35/02
Filed: 1987-01-22
Granted: 1993-04-13
Abstract: ABSTRACT      The present invention provides an improved filtration system particularly adapted for use in a fluid circulation system in a moving body.  The filtration system includes a filter body formed from a porous resilient material.  The filter body is not designed to be limited to a predetermined space for a filter and thus greatly increases the filter area/mass  ratio.   The  filter defines  a  large number  of tapered and winding passageways which are oriented at a large number of different angles relative to the outer sur-face of the filter body.  The passageways are sufficiently large to permit fluid and particles to flow through into them, but are sufficiently tapered so that any particulate matter within the  fluid becomes entrapped in the tapered passageways.  The walls of the tapered passageways are po-rous  in  micron  and  sub-micron  dimension  to  freely  pass fluid.   Accordingly, fluid will freely  pass  through  the filter but any impurities or particulate matter will be firmly  retained  within  the  tapered  winding  passageways.          Moreover, as a result of the winding and tapered nature of the passageways defined within the filter, once particulate matter is entrapped within the filter, movement of the mov-ing body within which the filtration system is incorporated or flow of the fluid itself will not free the entrapped particles  in the tapered passageways,  but further embeds them.  The filter utilizes both qravitational and inertial forces to entrap particles and affirmatively prevent the recirculation of entrapped particles with the fluid carrier.

Title: Semiconductor device
Inventor: PELGROM MARCELLINUS J M
IPC: G11C27/04
Filed: 1987-04-02
Granted: 1991-10-29
Abstract: ABSTRACT: Semiconductor device.         The invention relates to a CCD having a so-called diode cut-off input, in which the input diode is applied to a reference voltage and the input signal is supplied to the input gate located in front of the first clock electrode. More particularly if the electrodes are composed of a trans-fer part and a storage part with incorporated potential difference, it is possible that, when charge is transported from the input gate to the first clock electrode, a large amount of charge is left behind. In order to avoid this and/or to be able to enlarge the dynamic range of the input signal, a MOST switch controlled by the same clock voltage as the first clock electrode is arranged between the input gate and a reference voltage, for example earth. This switch becomes conducting when the charge is transferred, as a result of which the potential level below the input gate can be adjusted above the surface potential below the transfer part of the first clock electrode.

IPC: D02J3/18
Filed: 1987-10-26
Granted: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE      Spun yarns are subjected to the vortex action of an impinging, circularly rotating fluid to lay down extending staple fibers against the yarn body while causing the yarn path to balloon and are then contacted with a melt size presented on a slower moving grooved melt size applicator.  As a result of the ballooned yarn path, the yarn wipes melt size from the sides and bottom of the groove, giving the yarn a smooth, substantially continuous coating on its outside surface.  Spun yarns so treated may be successfully woven as filling yarn on a water jet loom and knit as the warp yarn or as laid-in yarns on a knitting machine without excessive lint accumulation.

Allen LAROCHE                       ABSTRACT      A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a permeable, conformable material to a shape-defining surface of an expendable pattern.  The permeable, conformable material, when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface.  Upon heating, the material of the expendable pattern combusts or volatilizes and thus establishes the shaped cavity mold.  A molten parent metal is then vaporized with a vapor-phase oxidant in such a manner as to form a ceramic body which grows into the mold cavity, and is shaped by it.  The ceramic body is recovered from the mold having a shaped surface replicating the shape-defining surface of the expendable pattern.

Title: Machine for applying twist-type ties
Inventor: KNUDSEN DAVID S
IPC: B65B51/08
Filed: 1988-03-02
Granted: 1992-01-21
Abstract: ABSTRACT           A machine for applying a twist-type tie to the neck of a bag has a path and sets of endless belts which come together at a nip along the path to propel a bag neck which passes into the nip forwardly to a tying zone in the path.  Here a twist-type ribbon crosses the path and is secured at its end in a holder.  An endless chain carries a pusher tab up to the tying zone behind the bag neck, causing the bag neck to gather behind and deflect the ribbon, then pauses, and thereafter resumes its forward motion to drive the bag neck out of the machine.  During the pause a bag clamp secures the bag neck against a surface that is along the path and a needle lifts a portion of the ribbon upwardly behind the gathered bag neck and brings that portion of the ribbon to the holder so that the ribbon loops below the bag neck in the form of leading and trailing segments.  While the needle is extended, a twister hook gathers its leading and trailing segments and twists them together.  As the tie is completed, the holder shears the trailing segment of ribbon and at the same time grips that segment so the ribbon remains extended across the path.  A ribbon stripper moves forwardly from behind the twister hook and clears the severed twist tie from the tying zone as the pusher tab resumes its forward motion.
