Abstract: A sealing construction for a suction box of a suction roll in a paper machine and a method for sealing a suction roll in which a seal is arranged in a holder and loading members, preferably at least one loading hose, are arranged between the holder and the seal. The seal is pressed against an inner face of the roll mantle of the suction roll by the pressure of a medium that has been supplied into the loading hose. Locking devices are situated between the seal and the holder to lock the seal in a desired position, so that it is possible to remove the load from the loading hose, so as to minimize wear of the seal.

Abstract: A plastic bag having a reclosable plastic zipper is provided with a tamper-evident, non-reclosable peel seal formed by coextruding an adhesive onto a side strip adjacent to the interlocking zipper. The coextrusion causes the adhesive to preferentially adhere to the side strip when the peel seal is broken. A method for manufacturing the reclosable plastic zipper includes the steps of coextruding a zipper profile including a plane area with an adhesive on the plane area, slitting the profile lengthwise, and folding lover one of the resulting sides of the zipper to interlock them with one another.

Title: Apparatus and method for mobile (e.g., cellular or wireless) telephone call handover and impersonation
Inventor: ALDERMESHIAN HRAIR
IPC: H04M3/54
Filed: 1995-08-28
Granted: 1999-09-28
Abstract: One communications device (called the "impersonating" device) can selectively impersonate another communications device (called the "impersonated" device) by arranging the impersonating device to take over and/or use the same network identification number (typically stored in an identification number memory and used to control selection of incoming calls to which the device responds) normally associated with the impersonated device. As a result of impersonation, there is a hand-off between the devices, with the impersonated device becoming dormant and the impersonatingdevice becoming active, such that calls normally received by the impersonated device are received by the impersonating device, and such that calls originating in theimpersonating device get the identical network treatment as would be accorded to calls originated by the impersonated device, all of this without any need to adjust or update profiles stored in a network database. Impersonation can be triggered automatically, as by the physical proximity of one terminal device to the other, or manually, such as by pushing a button on one of the devices.

Abstract: An ionizing apparatus (11) that produces both positive and negative ions has a housing (12) with air inlet (14) and outlet passages (17), a plurality of spaced apart air ionizing electrodes (34,35) and a high voltage supply (51) which applies positive and negative voltages to separate electrodes (34,35). A fan (25) creates an airflow (24) that carries the ions out of the housing (12), the fan (25) preferably being between the electrodes (34,35) and the outlet passages (17) to promote intermixing of positive and negative ions. The high voltage region of the high voltage supply (51) is isolated from any direct current path to ground (47). The electrodes (34,35) then inherently acquire a D.C. voltage bias when necessary, that maintains an equal output of positive and negative ions without requiring use of an air ion sensor and feedback circuit for the purpose.

Title: Systems with increased information rates using embedded sample modulation and predistortion equalization
Inventor: NEWHALL EDMUNDE EUGENE
IPC: H04L27/00
Filed: 1993-07-09
Granted: 1998-10-06
Abstract: A system is described which achieves an increased rate of transmission by transmitting multiple symbols in one symbol time. The infor-mation in the overlapping symbols can be recov-ered if the symbol used for transmission is chosen so that a subset of the samples representing the symbol has an inverse. The construction of suit-able symbols is illustrated.  Effective operation of the system depends on equalization which will recover the baseband signal shape. Methods of equalization are depicted which are suitable for use with this system including equalization real-ized by predistorting the signal at the transmit-ter so that it arrives at the receiver undistorted. The invention is applied to baseband and pass-band systems and the application of predistortion equalization to the fading passband channel is de-scribed.

Abstract: An  implantable  atrial  defibrillator  delays  therapy intervention for a delay time period after initial detection of fibrillation to provide the atria with an opportunity to spontaneously   revert   to   normal   sinus   rhythm   before cardioversion is attempted.   A timer times the delay time period responsive  to  the   first   initial  detection  of fibrillation by a fibrillation detector.   After timer time-out,   the   fibrillation   detector   redetects   for   atrial fibrillation.    If  the atria  are  still  in  fibrillation,  a cardiovertor cardioverts the atria.   If the atria are not in fibrillation, cardioverting therapy is withheld.

Title: Method of installing a refractory lining
Inventor: SOOFI MADJID
IPC: F27B1/14
Filed: 1996-04-30
Granted: 1999-08-31
Abstract: A method is provided for installing a refractory lining in a metallurgical vessel having a main opening which is much smaller than the diameter of the vessel.  The method is especially useful in a vessel having a circular or otherwise curved cross-section.  A form or mold is assembled inside the vessel, leaving a space between the form and the outer shell of the vessel. The form is supported on both sides, to maintain the distance between the form and the outer shell, and to prevent collapse or implosion of the form.  Then, a pumpable casting composition having a smooth and easy flow is injected between the form and the shell, and allowed to harden.  The use of the pumpable composition significantly shortens the time required to form the liner.
