Title: Smooth muscle mitogen
Inventor: FOLKMAN MOSES J
IPC: A61K38/00
Filed: 1991-10-25
Abstract: ABSTRACT    A novel growth factor (BTC-CG) was purified from the conditional medium of pancreatic beta tumor cells initially derived from transgenic mice (RIPI-Tag2). The purification scheme included BioRex 70 chromatography, phenyl-Sepharose chromatography, TSL-GEL heparin FPLC and C4 reverse phase HPLC.  The peptide also stimulated proliferation of bovine smooth muscle cells.  It was not inactivated by boiling, by 10 mM dithiothreitol or by exposure to 1M acetic acid. Biological activity of BTC-GF was recovered from a single band of protein which had a molecular weight of 32,000 on SDS-PAGE.  The partial N-terminal amino acid sequence of this protein from BTC-3 and BTC-J10 cells was determined with an ABI 470A protein sequencer to be:            .

Patent CA-2056678-A1 (CA)
Inventor: BURGERS JOHN G
IPC: F28D1/03
Filed: 1991-11-29
Abstract: A flat plate type heat exchanger or evaporator is disclosed for use in automobile air conditioning systems.  The heat exchanger includes a set of stacked plate pairs,  the plate pairs having refrigerant fluid passageways extending laterally between the plates of each plate pair while the spaces between the plate pairs define air flow passages, these air passages having fins located therein.   In one aspect, fluid inlet and outlet passages are formed when differently sized tubes in adjacent plate pairs are telescoped together and subsequently brazed together to form a high surface area, fluid tight joint.   The resulting fluid tight joint formed between tubes in adjacent plate pairs exhibits greater rupture resistance  than  that  formed  with  drawn  cup  assemblies currently in use.  These refrigerant fluid inlet and outlet passageways  are  spaced  inwardly  from  the  edges  of  the evaporator and extend transversely through the stack,  the inlet and outlet passages being in flow communication with the lateral fluid passages located between the plates.  In this way, a greater percentage of the available frontal surface area of the evaporator is utilized for heat exchange.

Abstract: ABSTRACT OF THE DISCLOSURE              Elongated wood cants aligned in a given direction  are  displaced  laterally  from  a  first position to a second position without disturbing the alignment.   The apparatus comprises a first frame rotatable about a first axis,  and a second frame rotatable about a second axis parallel to but spaced apart from the first axis.   The apparatus further comprises first and second mechanisms for grasping the elongated  wood  cants.    The  first  mechanism  is pivotally mounted on the first frame about a third axis parallel  to the  first  axis,  and the second mechanism is pivotally mounted on the second frame about a fourth axis parallel to the second axis.  The third and fourth axes are spaced apart from the first and second axes, respectively, by a same distance. The two frames are simultaneously rotated about the first and second axes, respectively, and during this rotation the third and fourth axes occupy a same angular position with respect to the first and second axes,  respectively.   In operation,  the  first and second mechanisms grasp longitudinally spaced apart portions of the elongated cant in the first position and the two frames are rotated to displace laterally the wood cant to its second position where it is released still aligned in the given direction.  During rotation, the first and second mechanisms rotate on the first and second frames about the third and fourth axes, respectively.

Title: Shutterless optically stabilized capnograph
Inventor: YELDERMAN MARK
IPC: G01N21/35
Filed: 1990-08-27
Abstract: Methods and apparatus for constructing optically stabilized, shutterless infrared capnographs are disclosed. The capnographs of the present invention provide the absolute concentration of the constituents of the respiratory airstream of a patient, without the thermal drift problems normally associated with thermopile detectors, thereby providing a device with a high degree of accuracy.  The present invention eliminates the need for a mechanical shutter to modulate the incident infrared beam and the need for a modulated source, thereby increasing the reliability and response time of the devices disclosed. Capnographs which are substantially unaffected by changes in the ambient temperature at which they operate are provided by connecting pairs of filtered (60, 61, 62, 16, 18, 26, 28, 36, 38) thermopiles (12, 14, 22, 24, 32, 34) in series and processing the resulting differential signal (242).

Patent CA-2069725-A1 (CA)
Title: Two-phase brushless dc motor controller
Inventor: KRUSE DAVID L
IPC: H02P6/18
Filed: 1992-05-27
Abstract: Control circuits for operating a two-phase brushless do motor from a do power source are described. Control of the motor is optimized by detecting induced back EMS of the two phases to sense rotor phase position. It is common knowledge that the voltage developed across the terminals of a permanent magnet motor can be represented by a winding resistance, a winding inductance and a generated back EMF. In two-phase brushless do and permanent magnet stepping motors, the induced back EMFs of the two phases are displaced from each other by 90 electrical degrees. Thus, by detecting the back EMFs of the two phases, an accurate relative position of rotor-to-stator can be determined at any rotor position. Commutation of the motor phases and closed loop control of the motor and load is achieved by accurately sensing the back EMFs of the two phases. Also, phase position of the permanent magnet rotor poles is detected by integrating the sensed back EMFs of the two phases to produce quadrature sinewaves the magnitudes of which are constant relative, to rotor speed.
