Title: Non-linear optically active polycarbonate
Inventor: BOONSTRA TJERK O
IPC: C08G63/68
Filed: 1994-09-28
Abstract: NON-LINEAR OPTICALLY ACTIVE POLYCARBONATE            Abstract of the Disclosure The invention pertains to a non-linear optically active (NLO) side chain polycarbonate and to NLO active waveguides containing said polycarbonate.  Waveguides containing this NLO polycarbonate have a low loss of signal.  Polycarbonates based on bischloroformates of hexafluorobisphenol A , hexafluorotetrabromobisphenol A and bisphenol S or deuterated bisphenol A or sulphonylbiphenol are especially preferred within the framework of the invention: they were found to give an exceptionally low loss of signal.  The invention further pertains to cross-linkable and already cross-linked polycarbonates.  Especially preferred polycarbonates according to the invention are those where the diol comprises a rigid donor group.  These polycarbonates have a high Tg, which renders them thermally stable.

Inventor: DUFRESNE PETER
IPC: B01J20/34
Filed: 1995-03-24
Abstract: A  method  and  apparatus  for  regenerating  acidified perchloroethylene.   The perchloroethylene may be passed into contact with an anionic exchange resin for removing substantially all of the acidified compounds, typical of which are fatty acids. A further treatment is disclosed for removing dyes and related compounds.    The  treatment  involves  passing  the  treated perchloroethylene through a sorbent resin for subsequent removal of the dye.  The apparatus is simple and affords the regeneration of the perchloroethylene to a new quality for multiple uses after a deacidification.  The result is a more environmentally friendly method  of  handling  the  perchloroethylene  and  there  is  a substantial reduction in the amount of wasted perchloroethylene which would otherwise have to be delicately handled due to environmental concerns.

Title: Atp-diphosphohydrolases and process of purification thereof
Inventor: BEAUDOIN ADRIEN R
IPC: A61K9/00
Filed: 1995-05-08
Abstract: The present relates to two ATP diphosphohydrolases ATPDase enzymes isolated  from bovine aorta and pig pancreas, which enzymes have a molecular weight for their catalytic unit of about 78 and  54  Kilodaltons, respectively.  A novel process for obtaining a highly purified ATPDase is also an  object of the present invention.  This process has been successfully applied to the purification of both the pancreatic and the aorta enzymes and is deemed to work in the purification of any ATPDase.   For both sources of enzymes,  the process allows the  specific activity of  the  enzyme  to  be increased by at least 10,000 fold when compared to the activity retrieved in the crude cell homogenates. The novel process involves an  ion  exchange chromatography step, a separation on an affinity column, followed by an electrophoresis under non-denaturing  conditions.  The two enzymes purified by this  process  (aortic  and pancreatic) are glycosylated  and,  when  deglycosylated, have  molecular weights of about 56  and  35 Kdaltons, respectively.  Other embodiments of  this  invention: specific antibodies and  pharmaceutical  compositions, are also contemplated.

Patent CA-2156352-A1 (CA)
Inventor: SBALCHIERO FEDERICO
IPC: H02K15/16
Filed: 1995-08-16
Abstract: The balance of rotors for dynamo-electric machines (e.g., electric motor armatures), which are wound with two diametrically opposite, simultaneously applied coils of wire, is improved by ensuring that wire is fed to both coils in substantially similar quantities.  This can be accomplished by monitoring the lengths of the two wires as they are fed to the armature using wire sensors located adjacent to the flyer.  Alternatively, wire sensors can be provided to monitor the rate at which wire is being fed towards respective flyers and to measure the rate of change of the lengths of those portions of the wires that are supported by the winding machine dancer arms.  A control system processes the measurements from these sensors.  A wire tensioner having a hysteresis clutch is also provided that allows the tension applied to a wire being wound to be adjusted rapidly.  The wire tensioner also picks up slack that may develop in the wire.

Filed: 1991-12-19
Abstract: A method and apparatus for controlling the speed of a multi-phase, brushless DC electrically commutated motor (ECM). Voltage is commutated to the windings of the ECM based on rotor position information derived from back EMF or Hall effect sensors. The application of the commutating voltages is arranged such that the voltage applied to the windings always leads the back EMF generated in the windings by aselected constant lead angle. The speed of the motor is then controlled by pulse width modulating (PWM) the voltage applied to the windings of the ECM.

Patent CA-2166914-A1 (CA)
Inventor: CRAWFORD FERDON H
IPC: G01N33/49
Filed: 1996-01-10
Abstract: The present invention involves a method and apparatus for measuring the density or specific gravity of a fluid sample.  A reservoir (28) contains another fluid of known density which is not miscible with the fluid sample.  Sensors (32, 34) are disposed proximate to the reservoir to detect the passage of the fluid sample through the non-miscible fluid medium.  A microprocessor (50, 72) monitors the sensor and calculates the specific gravity of the fluid sample.  The microprocessor measures the amount of time one sensor is eclipsed at a point as the fluid sample droplet falls through the fluid medium and calculates the density or specific gravity based on that amount of time.  The microprocessor also may measure a second amount of time, the time required for the fluid sample to traverse through the fluid medium between two sensors.  The microprocessor can use this second amount of time to measure the fluid droplet diameter or size. The microprocessor corrects the calculated density or specific gravity for any deviation caused by the size of the fluid sample.

Inventor: GELLNER ROBERT C
IPC: G01S13/931
Filed: 1994-06-28
Abstract: A monopulse vehicular radar system for tracking a target about an automotive vehicle senses a transmitted signal reflected back from the target and received at two different locations, determines sum and the difference of the reflected signals sensed at the two locations, and compares the sum and difference to determine the deviation of the target from a reference azimuth. A source frequency provided by a Gunn diode (84) is applied to and difference by a two-lobe monopulse antenna (40). The antenna lobes detect the reflected signals from the target by sensing them at the two different lobes. A hybrid junction (74) provides sum and difference signals to mixes which homodyne the signals to produce sum and difference Doppler frequency signals using the source frequency. The Doppler frequency signals are amplified and then compared to determine the deviation of the target from the reference azimuth

IPC: B29C67/00
Filed: 1994-08-17
Abstract: The 3-D Model Maker (I) of the present invention is a device that builds three dimensional models of computer generated (e.g. CAD) structures by vector plotting layer-upon-layer applications of solidifiable substances.  The layers are formed by expelling minuscule beads of the substances in liquid or flowable phase onto a platform (10) from one or more jets (60), the jets and platform being relatively movable in X Y and Z coordinate system. The beads are deposited along vectors, during X/Y relative movement, on the platform (10), one at a time, layer-upon-layer, to build the model. The jets (60) and platform (10) are moved relatively to one another in accordance with instructions from the computer (controller) (11) to form each layer in the X-Y plane (in a manner analogous to an X-Y vector plotter) and either the platform (10) or the jets (60) may move in the Z direction to allow the jets to form subsquent layers.
