Title: Process for the galvanic application of a surface coating
Inventor: MUELL KARL
IPC: C25D5/18
Filed: 1994-10-01
Abstract: The invention relates to a galvanic coating process to provide a structured surface coating on a workpiece with an electrically conductive surface and a device for implementing the process. Here, the object to be coated is the cathode in a galvanic bath. The process current is raised in steps during a nucleation phase (10, 11) in which the stepwise increase in the current results in the formation of a deposit of individual or adjacent bodies on the surface of the object. The prooess current is then kept constant during a ramp working period (12), resulting in the growth of the previously produced nuclei or bodies. The process may be cyclically repeated.

Title: Position encoder with fault indicator
Inventor: SUGDEN DAVID MARK
IPC: H02P6/16
Filed: 1996-03-26
Abstract: A failure detector for a position encoder which uses a plurality of position sensors.   The failure detector receives position signals from the plurality of position sensors.    The  position  signals  represent  the  rotor position  for a  switched reluctance machine,  and  the position signals have allowable  states and allowable output state sequences that occur if the position encoder is operating properly.  If one or more of the plurality of sensors fail or the rotating element of the position encoder  is  damaged,  an  illegal  state  occurs  in the position signals from the position sensors.  The failure detector produces a failure signal upon the occurrence of an illegal  state.  In addition,  the  failure  detector monitors the sequence of the output states and generates a failure when the output states change in a sequence that is not one of the allowed sequences.  The machine controller can respond to the failure signal to stop machine operation or trigger an alternate positioning scheme.
Patent CA-2173651-A1 (CA)
Inventor: SUTHERLAND STEPHEN B
IPC: G06T1/00
Filed: 1996-04-09
Abstract: The present method renders scanlines of an image to an output device in a memory efficient manner.  The image is defined by a number of order objects, each of which is independently stored.  The procedure determines on a scanline basis the objects which influence the particular scanline and accumulates the rendering effect of the objects necessary for returning the scanline.  Once a scanline is returned, the procedure is repeated.  Objects are only partially rendered as required to pass on the necessary information as input for the next object.  This approach maintains the independence of the objects, allows interaction of objects, allows output to high resolution output devices in a memory efficient manner, and allows each object to be reproduced at the best resolution.

Title: Method of detecting blood constituent and kit therefor
Inventor: TOMIYAMA TETSUO
IPC: G01N33/68
Filed: 1994-12-27
Abstract: A method for detecting blood component in a sample comprising reacting a human erythrocyte membrane band 3 glycoprotein (band 3) in the sample and a hemagglutinin produced by a microorganism belonging to the genus Conidiobolus (CA) and measuring said band 3 glycoprotein contained in a complex produced by the reaction. Because band 3 can be detected specifically, at high sensitivity, and stably by the use of CA, the method ensures qualitative or quantitative, and accurate detection of human blood component in feces or contents of digestive organs, of which the determination of the presence or quantity of human blood component by hemoglobin is difficult.

Title: Modified polymeric material having improved wettability
Inventor: QUINCY ROGER B III
IPC: D21H17/22
Filed: 1996-06-25
Abstract: Proteins are applied to a polymeric article by contacting the polymeric article with a protein and exposing the contacted polymeric   article   to  a  frequency with a sufficient power dissipation for a sufficient period of time. A frequency range for applying proteins to a polymeric article is between about 5 kHz to about 40 kHz with a minimum power  dissipated of about 1 watt.  As a result,  polymeric articles so treated exhibit improved water wettability, proteins may be applied to the polymeric articles very rapidly and more uniformly than by other methods, and polymeric articles having selected zones of wettability may be produced.

Patent CA-2181646-A1 (CA)
Title: Endoscopic access assembly
Inventor: WILLIAMSON WARREN P IV
IPC: A61B17/34
Filed: 1996-07-19
Abstract: An access assembly to provide access for surgical instruments during endoscopic surgical procedures and simultaneously seal the access opening when the instruments is withdrawn is disclosed. The assembly has a base, and an elastomeric sealing element and a tubular conduit. The base has a flange and a neck. The elastomeric sealing element has an inner elongated central channel which provides a passageway for surgical instruments into a body cavity. The sealing element also has an outer inflatable sleeve. When the space between the inner channel and outer sleeve is inflated, a distal balloon portion of the sleeve is inflated and the inner channel is compressed to constrict the inner channel passageway and therefore provide a seal. The primary advantages of this access assembly are that it provides a precise passage into the channel so that the elastomeric sealing element is not inadvertently punctured, and it can be manufactured in a cost effective manner because the base of the access assembly provides a ready platform for manufacture and attachment of the sealingelement.

Abstract: An improved baby carrier-coat system. The coat now has two main parts: a double-hooded outer weatherproof covering and an inner pile coat for warmth. The pile coat can be removed and worn separately if the weather is not too cold. The hood system ensures an adequate flow of fresh air to the baby by using a mesh netting to direct air to the baby. The system also has a vest that comes to the waist so that it can be worn separately. The vest includes two covered feeding slots to allow for breast feeding without having to remove the vest, or the baby from the carrier. The baby carrier can be tied on in one design or FASTEX clips and pulls can be used to make putting the carrier on even easier. A zipper has been added to the carrier so that the center of the baby carrier seat can be opened to put the baby in or to remove the baby from the carrier without having to remove carrier entirely. I have also added pockets to the baby carrier so that small item or a bottle may be carried. The mother can wear the vest and pile coat; the vest and outer coat; or the vest, pile and outer coat together. These combinations increase the range of options for the coat.
