Granted: 1998-02-24
Abstract: The Prothrombin Time  (PT)  is used as a screening test for blood coagulation  factor  deficiencies  and  for monitoring  oral anti-coagulant therapy  using  coumadin.   Thromboplastin  reagents activate the extrinsic pathway of coagulation and are the basis for the Prothrombin Time (PT) test.  This invention describes the use  of  barium  sulfate  and  chaotropic  agents,  and  nonionic detergents,  for  the  extraction  of  sensitive  thromboplastin reagents from tissue.  Extraction with sodium thiocyanate alone also greatly enhances thromboplastin sensitivity.  This invention should be useful  for all thromboplastins and will  improve their sensitivity for all PT-based tests and specific assays.

Abstract: A robot hand receives a length of sealing strip and fits it onto a mounting flange surrounding a vehicle door opening.  The hand is carried by the arm of a robot. As the robot moves the hand around the periphery of the door opening, the hand grips the sealing strip and drives it through the hand and around a roller so as to lay it on the flange. An appropriate length of the sealing strap is supplied to the hand by means of a cassette. within which the sealing strip is coiled. The hand carries a pick-up plate which grips the cassette by means of locking members. An end of the sealing strip extends out of the cassette on a nose forming part of the inverted lid of the cassette. The cassette is then drawn towards the robot hand, forcing the nose into the entrance of the hand and thus placing the end of the sealing strip between a first pair of drive rollers which are thereafter rotated so as to drive the sealing strip out of the cassette and through the hand.

Granted: 2000-05-02
Abstract: A digital data transmission system comprises at least two data sub-systems connected to respective data termination units interconnected via a time-division multiplexed communications network having an internal system clock. The DTUs are part of the communications network and have their internal timing slaved to the network. The data sub-systems have independent timing from the communications network and therefore data sub-systems clocks will be liable to drift relative to the DTU clocks. The incomin data stream is applied to a FIFO memory, whose state is used to identify overate or underate conditions in the the transmitting sub-system. Clock adjustment data is transmitted with communications data in a superframe consisting of n frames of m bits each (where n, m are integers), and the received data steam is adjusted in accordance with said clock adjustment data to compensate the received bit stream for overate or underrate conditions.

Title: Method for determining air mass in a crankcase scavenged two-stroke engine
Inventor: FRANK RICHARD M
IPC: F02D41/32
Filed: 1991-02-05
Granted: 1994-05-17
Abstract: METHOD FOR DETERMINING AIR MASS IN A CRANKCASE SCAVENGED TWO-STROKE ENGINE                   Abstract of the Disclosure A method is described for determining the cylinder mass of air available for combustion in a crankcase scavenged, two-cycle engine, based upon the Ideal Gas Law relationship and indications of pressure, volume, and temperature of air in the crankcase chamber, at predetermined points in the engine operating cycle.  This is achieved by first determining the mass of air trapped and compressed in a crankcase chamber, and thereafter, determining the residual air mass remaining in the crankcase after the transfer of air to the associated combustion chamber.  Then, the actual air mass transferred to the combustion chamber is determined as a function of the difference between the trapped and residual air masses.  Engine trapping efficiency can be used to correct for air leakage from the combustion chamber prior to cylinder exhaust port closure.  The volume of the air within the crankcase chamber is derived as a function of engine cycle position, with crankcase air temperature being derived as a function of intake air temperature.  Air pressure in the crankcase is monitored with a pressure transducer.

Title: Method for fabricating a weldment
Inventor: MCGUIRE DARREL
IPC: B66C9/16
Filed: 1992-01-31
Granted: 1996-05-07
Abstract: The invention is an improved method for fabricating apparatus weldments such as, for example, wheeled end trucks for overhead cranes.  The apparatus has a pair of spaced, wheeled end modules, a pair of beams extending between the modules and at least one reference such as a reference plane used to initially align end modules placed in a fixture prior to beam-module attachment by welding.  The improved method includes the steps of positioning the modules with respect to the reference, tack welding each piece in position for permanent attachment to the modules and permanently attaching each piece to a module.  Permanent attachment includes applying welds in sequence to the first end of one beam, to the second and first ends (in that order) of the second beam and, finally, to the second end of the first beam.  Where each module-and-beam-end attachment has plural welding paths, preferred steps are described for the order in which each path at each beam end is to be welded.  The effects of heat-induced piece distortion, which is unavoidable, are essentially canceled and misalignment in the finished apparatus is substantially avoided.

Granted: 1995-06-06
Abstract: An extensible hanger support is provided for use in providing a spanning connection between two spaced apart joints or the like for supporting therefrom such items as ceiling fans, light fixtures and the like.  The support includes first and second extensible members which are telescopically axially movable between a fully collapsed condition and a fully extended condition.  These extensible members employ cooperative means which are normally in threaded engagement in such a manner that rotation of one of the members relative to the other results in axial movement toward either the fully collapsed condition or the fully extended condition depending upon the direction of rotation.  Each of these extensible members has a free end which carries joist engaging means for respectively engaging a ceiling joist.  The cooperative means includes quick release means for quickly releasing the members from their normal threaded engagement with each other while permitting quick sliding axial movement relative to each other only in response to axially applied forces to cause the members to extend toward their fully extended condition while permitting axial movement in the opposite direction only in response to rotational movement in a direction causing said members to be displaced to the collapsed condition.

Title: Method for controlling the energization of a thermal printing heating element
Inventor: GUENTHER STEPHAN
IPC: B41J2/35
Filed: 1992-09-14
Granted: 1998-08-04
Abstract: A method for controlling the energization of a thermal printing heating element by a succession of current impulses (I) separated according to a printing raster is described.  The current impulses (I) upon exceeding a pre-given energy content effect a printing event and in the case of falling below this energy content effect a preheating. At each raster time point (t1) the printing requirement is ascertained for a predetermined number of yet to follow raster time points (t2, t3) and for raster time points (t2, t1) without printing requirements and lying in advance of a raster time point (t3) with a printing requirement the current impulses (I1, I2) are progressively increased.  Through the use of this method a thermal printer with a high printing speed is achieved.
