Inventor: KUBO HIROSHI
IPC: H04L7/04
Filed: 1991-02-06
Granted: 1995-01-03
Abstract: A frame phase estimation method and circuit for estimating the phase of a received digital signal in which the lead phase of the received signal is successively delayed by an amount equal to a sample period of the signal, cross-correlation values for each delayed signal with respect to a known transmission pattern are calculated, and a predetermined number of cross-correlation values of subsequent phases are added to the cross-correlation value of each initial phase.          The true initial phase of the signal is estimated to be the initial phase corresponding to the maximum sum of cross-correlation values.

Title: Fire suppression systems
Inventor: NORTHILL BARRY W
IPC: A62C35/64
Filed: 1991-09-18
Granted: 1995-01-10
Abstract: A fire suppression system in which fire suppressant material is contained in a reservoir, the reservoir having an outlet and a system containing one or more nozzles from which the suppressant is delivered for fire suppressant purposes.  The system incorporates a valve between the reservoir outlet and the nozzle(s) the valve including a movable valve member and a valve seat which cooperates with the movable member.  The valve member is movable from a closed position with respect to the valve seat preventing communication of suppressant between the reservoir and the nozzle(s) to an open position permitting flow of the suppressant from the reservoir to the nozzle(s).  An actuator is provided to selectively open and close the aforesaid valve member.  The actuator maintains a fluid (preferably nitrogen) under pressure to maintain the valve member in the closed position and is operable to vent the fluid to lower the pressure in the valve, thus permitting the valve member to open.  A coupling arrangement joins the reservoir outlet to the valve such that suppressant under pressure is conducted from the reservoir through the coupling member.  A check valve is located between the duct through which fluid is conducted from the actuator into the system and the coupling device through which suppressant is conducted from the reservoir into the system.  This check valve prevents flow from the coupling device in a reverse direction towards the actuator.

Title: Electronic delay circuit for firing ignition element
Inventor: GOTO TUGIO
IPC: H03L3/00
Filed: 1993-03-16
Granted: 1997-10-14
Abstract: An electronic delay circuit for firing an ignition element.  The delay circuit includes a  capacitor which stores electric energy supplied from an electric blasting machine, an oscillator generating a clock pulse train, a circuit for over-exciting the oscillator, a counter which counts clock pulses of the clock pulse train, and a circuit for maintaining a reset state of the counter for a predetermined time period after the electric energy is supplied.  The counter produces a trigger signal when it counts a predetermined number of the clock pulses, and the electric energy stored in the capacitor is discharged to the ignition element.  Since the oscillator enters into the steady state in a very short time by the over-excitation, the delay circuit has large resistance to external noise.

Abstract: A diverter interfaces first and second telecommunication lines from first and second telecommunication sources, respectively, with a third line coupled to a station set.  The diverter includes separate line and set monitors and a control unit.  The line and set monitors monitor and detect predetermined selective signals such as (a) ringing signals propagating on the first and second lines, and (b) line access codes, flash hook, and line change requests signals generated by the station set.  In response to the detected predetermined selective signals, the line and set monitors generate first, second, and third output control signals representative of the predetermined selective signals on the first, second, and third lines, respectively, to the control unit.  The control unit, which is responsive to output signals from the line and set monitors, selectively couples a predetermined one of the first and second lines directly to the third line without interfering with the predetermined selective signals and states present on the first, second, and third lines.  The control unit also generates predetermined output control signals to the line and set monitors for generating output signals such as call waiting signals for transmission to the station set on the third line.  The diverter is powered from the first and second lines, and its actions remain invisible to and do not affect the first and second telecommunication sources and the station set.
