Patent FI-98687-C (FI)
Inventor: WARSTA MARKUS
IPC: H04W76/04
Filed: 1993-09-20
Granted: 1997-07-25
Abstract: A mobile communication system and a method for connecting a remote workstation to a data network via a mobile communication network. The invention allows a remote workstation (3, 4) to be connected more flexibly over the radio path by providing a special interconnecting computer (19) in conjunction with the mobile exchange (10, 15) for extending the connection to a destination data network (24). The interconnecting computer (19) thus acts as a bus between the remote workstation using the mobile communication network and its home data network, simulates the operation of the remote workstation towards the data network (24), and takes care of the real remote workstation (3, 4), which is behind the radio path. A data connection established over the radio path can be released so as to minimize the air time when the radio path is not needed for telecommunication, but the interconnecting computer (19) keeps the extended connection active towards the data network. <IMAGE>
Patent NO-148168-C (NO)
Inventor: ASH CHRISTOPHER PATRICK
IPC: H04B3/06
Filed: 1980-09-10
Abstract: The presence of a d.c. offset in the input signal to an adaptive equalizer for a high speed modem must be removed before a valid signal enters the equalizer if the "coefficient up-date" algorithm for the equalizer is not to be confused. Normally the d.c compensation is achieved using adjust-on-test resistors or potentiometers which provide for in life adjustments to compensate for ageing drift. The submission envisages the use of an additional adaptive equalizer tap-stage connected to a fixed voltage source. This voltage is multiplied by the additional tap-stage multiplier and summed with the outputs of the other tap-stages in the equalizers accumulator. The error produced from the equalizer decision circuit is correlated with the fixed voltage in the additional tap-stage correlator the output of which controls the gain of the additional tap-stage multiplier thereby compensating for the original d.c. offset of the output of the equalizer accumulator.

Abstract: This invention concerns a family of chimeric antibodies with high affinities to a high molecular weight, tumor-associated sialylated glycoprotein antigen (TAG72) of human origin.  These antibodies have (1) high affinity animal V H and V L sequences which mediate TAG-72 binding and (2) human C H and C L regions.  They are thought to produce significantly fewer side-effects when administered to human patients by virtue of their human C H and C L antibody domains. The nucleotide and amino acid sequences of V H.alpha.TAG V H, CC46 V H, CC49H, CC83 V H, and CC92 V H, and CC49L, CC83 V L, and CC92 V L idiotype sequences are disclosed, as well as in vivo methods of treatment and diagnostic assay using these chimeric antibodies.

Title: Combination container and pump
Inventor: SUGITA KOICHI
IPC: B65D83/00
Filed: 1990-10-16
Granted: 1997-01-28
Abstract: A pump is mounted in one end of a cylindrical con-tainer for storing a liquid, for drawing the liquid stored in the cylindrical container and discharging the drawn liq-uid out of the cylindrical container.  A gasket is slidably disposed in the opposite end of the container in keeping the liquid sealed in the cylindrical container.  The gasket is movable toward the pump as the amount of the liquid stored in the cylindrical container is reduced when the liquid is discharged from the cylindrical container by the pump.  The gasket has a slanted surface facing the pump for contact with the liquid stored in the cylindrical container, the slanted surface being inclined progressively toward the sec-ond axial end.  The gasket also has a cylindrical surface defining a communication hole defined axially therethrough and having an inner end opening at the slanted surface.  The communication hole provides communication between the inte-rior and the exterior of the cylindrical container.  A cap comprises a cap body inserted in the communication hole and a flange closing an outer end of the communication hole.  At least either one of the cap body and the cylindrical surface has at least one axial groove.  Air bubbles which may have been trapped in the container when the liquid is charged into the container move along slanted surface into the com-munication hole and then is escaped from the container through the groove.

Filed: 1991-06-13
Granted: 1995-08-22
Abstract: A door apparatus for a railway hopper car for discharging bulk material from the car has an elongated flexible hollow body positioned in a discharge opening.  A pair of end walls are attached to opposite ends of the body. Each end wall has a first pivot point for rotary attachment to the body.   The body is rotatable about the first pivot point between an opened position and a closed position. The body has an arcuate surface extending generally vertically when in the closed position to reduce the effort required to open the doors when the car is loaded.  If the door apparatus is stuck in the closed position, such as when ice has formed between the longitudinal edge of the door apparatus and the edge of the discharge opening, a torque applied to one end of the door apparatus about the first pivot point tends to twist the door apparatus about the longitudinal axis.
