Title: Apparatus and method for high speed determination of received rf signal strength indicator
Inventor: PERRY FRED G
IPC: H04B7/26
Filed: 1987-10-02
Granted: 1992-10-20
Abstract: APPARATUS AND METHOD FOR HIGH-SPEED DETERMINATION   OF RECEIVED RF SIGNAL STRENGTH INDICATOR     ABSTRACT OF THE DISCLOSURE           Rapid measurement of the received signal strength indicator (RSSI) of a radio frequency signal is performed by sampling received signal amplitudes and averaging only selected ones of the sampled amplitudes.  In one embodiment, two sample values obtained successively in time are compared and the larger of the two is stored, this process continuing over a desired sampling interval.  Sampled values which exceed both the value obtained from an immediately preceding sample time and the value obtained from an immediately succeeding sample time are stored twice, while sample values which are less than immediately preceding and succeeding sample values are never stored.  The stored values are averaged to yield an indication of average received signal amplitude.  The resulting average value is very close to true average signal amplitude, is substantially unaffected by Rayleigh fading phenomenon, and yet is sensitive to rapid changes in received signal amplitude caused, for example, by obstacles in the signal transmission path.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method and apparatus for producing tobacco smoke filter rods.  In the method, filter tow comprising crimped spun fibers and/or filaments is prepared in a preparation zone and fed to a processing zone.  There it is gathered, in an intake zone, then wrapped and cut into tobacco smoke filter rods.  In the region of the intake zone, a gas or vapor under elevated pressure acts on the filter tow at an angle of less than 90° to the longitudinal axis of the filter tow in the direction of movement of the filter tow, The apparatus for carrying out the method, has a preparation unit and a processing unit,  the latter unit containing for feeding a gas or vapor under elevated pressure to the filter tow in the direction of movement thereof:  an intake finger having holes in the wall thereof on the filter tow intake side/ or a pipe, whose gas or vapor exit and terminates in the region of the filter tow outlet side of the intake funnel or the filter tow intake side of the intake finger, a blowing device immediately upstream of the filter tow intake side of the intake finger.   The invention solves,  in particular, the problem of non-uniform drawing resistances in the manufacture of tobacco smoke filter rods.

Title: Vertical injection apparatus
Inventor: ISHIMOTO KENJI
IPC: B22D27/11
Filed: 1987-11-30
Granted: 1992-03-10
Abstract: VERTICAL INJECTION APPARATUS     ABSTRACT OF THE INVENTION      A vertical injection apparatus is incorporated with a parting mold including upper and lower mold halves and defining a cavity to be filled with a melt.  The lower mold half has a vertical sleeve hole at the outer side thereof and a vertical melt passage hole communicating between the cavity and the sleeve hole.  The upper mold half has a vertically extending pin hole coaxial with the melt passage hole and open to the cavity and provided with a vertically extending mold pin movable through the pin hole.  At least an upper part of the melt passage hole in the vicinity of the cavity has a diameter smaller than that of the sleeve hole but slightly large than the of the mold pin.  Preferably, the cavity is designed for a disk wheel having a central hole through which the mold pin is allowed to pass, and the lower mold half forms a contoured inner surface corresponding to a decorated surface of the disk wheel.  After the mlet in a sleeve is injected by a plunger into the cavity through the melt passage hole, the mold pin is forced to move to a lower position so that a lower free end portion of the mold pin is inserted into the melt passage hole through the cavity, thus urging the melt filled in the cavity and the melt passage hole against the surface of the cavity.

Abstract: Inventor:  James W. Davis, a citizen of the United States of America and resident of New Britain, Pa.                     ABSTRACT OF DISCLOSURE       An electromagnetic flowmeter having a frame assembly formed by an octagonal metal frame within which are mounted a pair of electromagnets and a pair of electrode holders.          The electromagnets are secured to one set of opposing sides of the frame along a first transverse axis which passes through the geometric center of the frame while the holders are secured to another set of opposing sides along a second transverse axis which passes through the center at right angles to the first axis.  The frame assembly is encapsulated within a generally cylindrical plastic insulating body of polymeric material having a longitudinal bore therein defining a flow conduit whose flow axis passes through the geometric center of the frame and is perpendicular both to the first and second transverse axes whereby when fluid flow therethrough it intersects the magnetic lines of flux produced by the electro-magnets.  The resultant voltage induce in the fluid is a function of its flow rate and is picked up by the electrodes to provide a flow rate signal.  To prevent the plastic body from cracking as a result of differences between the thermal coefficient of expansion of the metal frame and that of the polymeric material, an interfacial layer is formed therebetween having elastomeric properties.
