Title: Pager receiver for enabling to omit power-on signal for receiving synchronization code in pager signal
Inventor: IDE MOTOKI
IPC: H04W88/02
Filed: 1991-10-24
Granted: 1996-04-02
Abstract: A pager receiver is assigned to a particular call number and is for receiving pager signals of a predetermined baud rate by use of the battery saving technique.  Each of the pager signal comprises a synchronization code signal and a plurality of address signals, each of the address signals comprising a call number and a message, a particular one of the address signals being assigned to the  pager receiver.  The pager receiver is driven by a power-on signal at a timing for receiving the particular address signal.  The pager receiver has a baud rate monitoring circuit for detecting the predetermined baud rate of a signal received to produce a monitoring signal, and a comparing circuit for comparing the call number in the particular address signal with the particular call number to produce a coincident signal.  When both of the monitoring signal and the coincident signal are present at a time, the pager receiver drives an indicator.

Title: Method and apparatus for installing a pipe liner
Inventor: GARGIULO JOSEPH L
IPC: F16L55/165
Filed: 1992-05-21
Granted: 1997-02-04
Abstract: Apparatus for installing a liner in a pipe by reducing the diameter of an elongated tube of lining material, to allow it to be positioned within the pipe, heating the tube of lining material to soften it, and expanding the tube of lining material within the pipe to form a liner, includes a plurality of disk-shaped expanders for engaging the tube of lining material from the inside, and expanding the lining material to form a liner, an elongated body member for holding the disk-shaped expander in a spaced apart at least generally parallel orientation, and bypass means for conducting a heated fluid past the disk-shaped expanders from a first end of the apparatus to a second end.  A method for installing a pipe liner in a pipe includes the steps of reducing the diameter of the liner, so that it can be positioned within the pipe, installing the liner in the pipe, enlarging an upstread end of the liner, disposing a liner expander within the upstream end of the liner, pressurizing the upstream end of the liner with a heated fluid, the temperature of the heated fluid being sufficient to soften the liner, and the pressure of the heated fluid being sufficient to propel the liner expander from the upstream end of the liner to a downstream end, providing means associated with the liner expander for allowing a portion of the heated fluid to bypass the liner expander for heating and softening the liner ahead of the expander, as the expander is propelled by steam pressure from the upstream end of the liner to the downstream end of the liner, while maintaining a propelling pressure upstream of the expander, retaining the expander at least partially within the liner at the downstream end, for pressuring substantially the entire length of the liner, and reducing the temperature of the pressurizing fluid to cool the liner below the softening temperature, to allow it to stiffen and form a liner within the pipe.

Abstract: Method and device of acoustic flow measurement for measuring the flow velocity of a gas and/or of quantities that can be derived from same. Acoustic signals are transmitted into a measurement pipe. The acoustic signals passing in the gas flow downstream and upstream are detected by means of two sound detectors placed in connection with the measurement pipe a.t a specified distance from one another, the flow velocity of the gas that flows in the measurement pipe being determined by making use of polarity correlation of said signals. The frequency of the sound that is transmitted into the measurement pipe is scanned between a certain minimum and a certain maximum frequency. The measurement signals arriving from the two sound detectors are passed to a narrow-band filter or system of filters. The passband of said filters is scanned synchronously with the frequency scanning of the sound transmission. The duration of the frequency scanning and the width of the passband of said filters are chosen so that, at the moment of the measurement sequence, the measurement signal detected by each sound detector has access through its filter substantially without attenuation, as well as so that the interference frequencies substantially different from the mean frequency of the filters are attenuated significantly.

Inventor: GREENE BOYD B
IPC: B01D17/02
Filed: 1993-08-16
Granted: 1998-06-23
Abstract: An apparatus and method for removing particles of a first liquid from a second liquid using Stokes' law, the first liquid, such as oil, having a greater buoyancy than the second, such as water, with both liquids being immiscibly combined into a flowing fluid mixture.  Surges in the mixture's flow are dampened, and the mixture is constrained to have a limited horizontal flow velocity through the tank of the apparatus.  A separator chamber with a plurality of parallel subchannels formed by spaced vertical plates has a geometry that reduces and controls the Reynolds number of the subchannels and controls the velocity through the subchannels, causing the flow therethrough to be substantially non-turbulent.  A first gate inhibits the flow of sediment into the separator chamber.  The flow path length through the separator chamber is such that the particles will have sufficient time to rise above a downstream exit, near the bottom of the separator chamber, and into a holding chamber.          A transverse velocity gradient formed within the subchannels causes the particles to spin and follow a curved path toward the lower longitudinal velocity regions adjacent the walls of the subchannels where the particles agglomerate and rise to the surface.  A vertical rising unit is optionally provided to remove very tiny particles that have insufficient buoyancy to rise above the separator chamber's exit, and various filters may remove other impurities.

Granted: 1998-08-25
Abstract: An object of the present invention is to provide an access system which can accommodate constant bit rate data irrespective of the traffic conditions and which also allows accommodation of variable bit rate data at a high circuit utilization efficiency.  The access system is constructed such that a master station first performs allocation of transmission right for constant bit rate data to all of slave stations for each transmission period for constant bit rate data.  The master station does not immediately perform allocation but reserves requests for transmission right for variable bit rate data, and after allocation of transmission right for constant bit rate data to all of the slave stations, the master station allocates the requests for transmission right for variable bit rate data to non-used regions within the transmission period.

Title: Pulsed electronic article surveillance device employing expert system techniques for dynamic optimization
Inventor: BALCH BRENT F
IPC: G08B13/24
Filed: 1995-08-01
Granted: 2006-06-06
Abstract: An electronic article surveillance system has a receiver with a plurality of receiving coils. Each coil in the system is treated as a separate detection unit with its own noise environment which is distinct from the noise environments of the other coils in the system. This allows the system to optimize its performance by maximizing the sensitivity of each coil according to its own local noise environment. In EAS systems in accordance with the invention, the priority of the detection routines is to keep an accurate and up-to-date picture of the noise environment for each coil in "noise phases" and to look for tags during "transmit phases". Upon tag detection, a controller establishes a validation sequence comprising a number of cycles and can change the number of cycles adaptively to the noise environment.
