Filed: 1996-12-20
Granted: 2000-11-28
Abstract: The present invention provides a process for treating arsenic-containing waste water, comprising adding an oxidizing agent, if necessary, to arsenic-containing waste water to oxidize trivalent arsenic in the waste water into pentavalent arsenic; adding a calcium compound to adjust the pH to 12 or higher; separating it into solid and liquid (first solid/liquid separation); calcining the resulting sludge, while adding a ferric salt to the treated solution to adjust the pH to 6-9 after the solid/liquid separation; and separating it into solid and liquid (second solid/liquid separation).  According to the present invention, it is possible to remove arsenic from waste water efficiently to yield treated water satisfying various tolerance limits under various regulations, while the arsenic-containing sludge separated from the waste water can become harmless in subsequent continuous steps.

Abstract: A molten glass gob distributor for a glass article manufacturing system that includes a gob discharge, and at least one scoop for receiving gobs from such discharge and distributing the gobs among a plurality of troughs or chutes leading to associated molds in a multiple-cavity IS machine. The scoop is coupled by a cogged drive belt to an electric motor for oscillating the scoop through a cyclic path adjacent to the troughs or chutes. Rupture at the drive belt is detected by coupling first and second electronic sensors to the motor and the scoop so as to provide respective first and second electrical signals as functions of motion at the motor and scoop. Rupture at the drive belt is indicated as a function of a difference between the first and second signals, indicating loss of synchronization between the drive motor and the associated scoop.

Title: Sinus preference method and apparatus for cardiac pacemakers
Inventor: MARKOWITZ H TOBY
IPC: A61N1/368
Filed: 1995-11-13
Granted: 2003-12-23
Abstract: A dual chamber, rate-responsive pacemaker for pacing a patient's heart novel ly allows tracking of the patient's sinus rate when the sinus rate is slightly less than the sensor rate; i.e., within a predetermined "Sinus Preference Window Maximum Rate Drop". Pacing at the sensor rate occurs when the sensor rate exceeds the sinus rate by more than the Sinus Preference Window Maximum Rate Drop. In the preferred embodiment a Sinus Preference Window, which occu rs at the end of the ventricle-to-atrium interval, is decremented with successi ve heart beats by a programmable delta to increase the pacing rate until the Sinus Preference Window reaches zero, in which case the pacemaker paces at t he sensor rate. The Sinus Preference Window is reset to its maximum value upon either the detection of an atrial sensed event, or upon the expiration of a programmable Sinus Check Interval. The pacemaker paces at the sinus rate or the maximum rate drop rate, whichever is faster, for a number of recovery beats, and then increments the pacing rate up to the sensor rate.

Abstract: A burner replacing system comprising a rail mounted in a ring around the outer periphery of burners mounted radially at the middle of a gas turbine; a carriage which turns around the burners via the rail; a pull-out slide which is supported on the carriage via a rotary shaft which turns the slide up and down in the direction of a center axis of the gas turbine and a rotary shaft which turns the slide right and left around a radial axis of the gas turbine and which moves in the direction of axis of the burners radially disposed; and a hand, supported by the pull-out slide via a centering slide which moves up and down in the radial direction of the burner, for gripping the burner. Another burner replacing system comprises a rail mounted in a ring around the outer periphery of a plurality of burners radially disposed; a carriage which moves along the rail; a pull-out slide which is supported by the carriage and moves forward and back in the direction of axis of the burner; a telescopic slide which is supported by the pull-out slide and expands in the direction of axis of the burner; and a hand, provided at the edge of the telescopic slide to grip the burner. Thereby, the burner replacing works are mechanized and the burner may be replaced at one time without requiring any man power and without dividing it into parts, so that the work period may be shortened and the man power can be saved considerably in replacing the burners. Further, the burner replacing system of the present invention allows the safety in replacing the burner to be improved and the burner or the gas turbine not to be damaged because the accuracy of works in replacing the burner is enhanced, thus eliminating the cost or the work period for the repair.

Title: Insulated modular injection nozzle system
Inventor: PURI RAJAN
IPC: B29C45/20
Filed: 1998-01-15
Granted: 2006-12-12
Abstract: A modular injection nozzle system for use with hot runner injection machines employs a thermal insulating element between the tip of the injection nozzle and a removable mold gate insert. This thermal insulating element limits the heat loss from the tip to the gate insert, assists in sealing the gate area and provides assistance in aligning the gate and the nozzle during assembly. The removable mold gate insert allows for eased servicing and assembling/dis-assembling of the injection nozzle system and has limited contact with the mold plate. In one embodiment, the removable gate insert is mounted to the nozzle via the insulating member, which is in the form of a sleeve with exterior threads which are complementary to interior threads on the gate insert. The sleeve can either be press-fit onto the nozzle or can have interior threads which are complementary to exterior threads on the nozzle. In either case, the sleeve can assist in the alignment of the components of the nozzle system. In another embodiment, the insulating element also includes a gap between the nozzle tip and the gate insert, the gap having a suitable insulating gas or vacuum therein to provide additional insulation. In another embodiment, the insulating element comprises a layer of insulating material on the nozzle tip and the gate insert can either be press fit with the layer or the layer can have exterior threads to engage complementary threads on the gate insert. In another embodiment, the insulating element is molded in place on the nozzle tip. In another embodiment, the insulating element is molded in place in the gate insert, and comprises interior threads which are complementary to exterior threads on the nozzle.

Abstract: A Central Office voicemail system permits a customer to monitor incoming calls and decide whether or not he wishes to take the call.  When a call is made to a called party (customer) and the called party does not answer the phone the call is transferred to voicemail in the usual way.          Additionally, a special ringing tone is applied automatically by the Central Office to the called party line.  This has the effect of alerting the called party to the fact that the caller has been transferred to voicemail.  The called party can then monitor the message being left simply by lifting his phone and, if he wants to talk to the caller, he simply carries out a hookswitch flash.  Alternatively, with a specially adapted terminal, the called party does not even have to lift the phone to monitor the message because the special ringing tone causes his terminal to go automatically into off-hook hands-free mode.
