Abstract: ABSTRACT    An apparatus for pasting a battery collector assembly having a current collector and enlarged members having a top surface and a bottom surface and a thickness greater than the current collector is provided.  The current collector has at least one predetermined area into which paste is to be filled to a predetermined first level on one side of the current collector and a predetermined second level on the other side of the current collector to form a paste layer of predetermined thickness less than the thickness of the enlarged members.  The apparatus comprises a reservoir for electrochemically active paste, a paste-dispensing nozzle having an orifice located in a dispensing end of the nozzle, and a feed conduit connecting the paste reservoir and dispensing nozzle and operable to supply paste to the dispensing nozzle.  The nozzle is mounted to dispense paste in at least one more paste area of the collector assembly.  A valve is provided which is operable to control the flow of paste from the nozzle such that paste is dispensed therefrom and flows into the paste area. The nozzle dispensing end is adapted to size the first level of paste dispensed in the paste area, and a surface is provided opposite the dispensing end of the nozzle which is adapted to size the second level of paste dispensed in the paste area.  The clearance between the nozzle dispensing end and opposing sizing surface is adjusted such that paste is dispensed from the nozzle, flows into the paste area of the collector assembly, and is sized such that the first level is intermediate the top surface of the enlarged members and the current collector and the second level is intermediate the current collector and the bottom surface of the enlarged members.  Thus, the enlarged portions of the collector assembly are left substantially free of paste.

Title: Device for improving the current output of a chargeable battery at low outside temperatures
Inventor: BRAUN DIETER
IPC: H01M10/6571
Filed: 1992-12-17
Abstract: ABSTRACT OF THE DISCLOSURE The object of the invention is a battery heating device with a temperature sensor and at least one heating element in a liquid and acid-proof arrangement inside the battery.  The heating element is a power transistor secured to a cooling plate which can be powered by the battery, the emitter of which is powered by a temperature control circuit when the battery temperature falls below a predetermined reference temperature and the battery voltage is higher than a lower threshold and lower than a higher threshold.  A trigger circuit is fitted which responds to the rise in the battery voltage after the current in a user with a high current consumption has been switched off.  The trigger circuit actuates a time circuit which conductively controls the power transistor for a set time if the battery voltage is under or at the lower threshold.

Abstract: A mechanism is disclosed for converting oscillatory rotation of an input shaft to unidirectional rotation of an output shaft.  An input shaft journalled to a frame is rotatable about an input axis, over a range of rotational positions, between a forward limit and a reverse limit.  An output shaft journalled to the frame is rotatable about an output axis, which is normal to the input axis.  Three bevel gears are employed, namely a first gear coupled to the input shaft, a second gear coupled to the input shaft and spaced axially from the first gear, and a third gear coupled to the output shaft.  The bevel teeth of the three gears are arranged in peripheral arrays covering cover less than one half of the entire periphery of each gear, so that the bevel teeth of the third gear intermesh only with the bevel teeth of the first gear whenever the input shaft rotates from the reverse limit toward the forward limit, and so that the bevel teeth of the third gear intermesh only with the bevel teeth of the second gear whenever the input shaft rotates from the forward limit toward the reverse limit.

Title: Truncated tissue factor and fviia or fvii activator for blood coagulation
Inventor: MORRISSEY JAMES H
IPC: G01N33/68
Filed: 1993-05-12
Abstract: It has been discovered that it is possible to administer truncated tissue factor, not having the transmembrane region, (tTF) in combination with factor VIIa (FVIIa) or an activator of endogenous factor VII to treat bleeding disorders such as those resulting from hemophilia or cirrhosis of the liver. The tTF is administered to produce up to 10 pg tTF/ml of plasma. The FVIIa or FVII activator is administered to produce levels of between 40 ng VIIa/ml and 700 ng FVIIa/ml of plasma.  The effective dosages of both tTF and VIIa/factor VII  activator are significantly and surprisingly less than the administration of either alone to stop bleeding. Examples demonstrate safety and efficacy in normal and hemophilic dogs.

Inventor: GALLAGHER JAMES E
IPC: G01F1/42
Filed: 1994-12-21
Abstract: A flow conditioner for use in pipelines to isolate a measuring device from the effects of piping induced disturbances thereby allowing more accurate metering of fluids flowing in pipelines.  The device comprises three sections:  an anti-swirl device; a settling chamber; and a profile device.  The three sections are installed in a pipeline at a predetermined distance upstream from a metering device and at a minimum predetermined distance downstream from a pipeline disturbance.  In the pipeline, the anti-swirl device is the furthest upstream, followed by a settling chamber of a specified length, which in turn is followed by the profile device.  The anti-swirl device substantially eliminates swirl, the settling chamber minimizes interaction between the anti-swirl device and profile device.  The profile plate produces pseudo-fully developed turbulent structure and velocity profile so there is a minimum deviation of the empirical discharge coefficient or meter calibration factor for both short and long piping lengths.  In certain circumstances, the unique profile plates provided may be used without anti-swirl devices.
