Patent CA-2043004-A1 (CA)
Inventor: NAGASHIMA SHINICHI
IPC: F02N15/02
Filed: 1991-05-22
Abstract: In a starter system for an internal combustion engine, an input member of an overrunning clutch is provided with an annular shoulder surface abutting an annular end surface of a cylindrical boss portion of a reduction gear unit casing when the overrunning clutch is at a rest position, and a cylindrical sleeve portion extends from the annular shoulder surface towards the reduction gear unit so as to be closely fitted an the cylindrical boss portion of the reduction gear unit casing. Thus, water and other foreign matters are not only shut off by these mutually abutting annular surfaces, but also prevented from reaching this region by the cylindrical sleeve portion closely fitted on the cylindrical boss portion of the reduction gear unit.      Also, the centrifugal force prevents water and other foreign matters from reaching this area when the starter is actuated and the two annular surfaces are not in contact.

Patent CA-2051142-A1 (CA)
IPC: H01F27/02
Filed: 1991-09-11
Abstract: A motor control system includes a single, multicompart-ment enclosure mounted on a skid.  The enclosure contains a transformer circuit and a motor controller circuit intercon-nected so that only external connections to a power source and a load are needed.   When the circuits are energized, access to high voltage motor control components and to field replaceable fuses and output selection switches is prevented by a double interlocking mechanism which operates in con-junction with energizing and de-energizing the transformer. The transformer of the transformer circuit includes a ter-tiary winding disposed radially between a primary winding and a secondary winding.  The winding filters electrostati-cally  coupled  transients.    A  conventional  electrostatic shield  is  also  used  so  that  the  transformer  is  doubly shielded to electrostatic transients.  The tertiary winding is connected to one or more capacitors to filter magneti-cally coupled transients.   A current limiting fuse, a load sensing fuse and a primary make/break switch are connected in electrical series to the primary winding.   Methods for energizing or operating a motor utilizing the primary switch and the load sensing fuse are also disclosed.

Patent CA-2061556-A1 (CA)
Title: High-strength, high-modulus, compound-filament or film-laminate implant and method for producing it
Inventor: GOGOLEWSKI SYLWESTER
IPC: B29C70/06
Filed: 1992-02-20
Abstract: Abstract of the Disclosure High-strength,  high-modulus,  polymeric  implants  are produced from  highly  oriented  monofilaments  and/or  films  by solvent welding technique.  This avoids loss of orientation,  as well as thermal and oxidative degradation, which is the common case with the  state of  art techniques,  namely melt extrusion, injection molding and heat  compression molding.  The  invention  leads to uniform bonding of the separate  structural units (monofilaments or  films)  into  compound-filament  or  compound-laminate which protects  the  implant  against  delamination.  Monofilaments of films are swollen at the  surface with a  suitable solvent which does not destroy the orientation in the core. A bundle, resp.  a sandwich  of  the  swollen  monofilaments  or  films   is pulled through an orifice generating  compressive stresses  between the filaments,   resp.  films.  Solvent  removal  from  the  swollen compressed interfaces  leads  to  a  homogenous  welding  of the monofilaments or films.

Abstract: INTEGRATED CONTROL AND SIGNAL               PROCESSING IN A CELLULAR TELEPHONE                    ABSTRACT OF THE DISCLOSURE   Control functions are integrated into the digital signal processing (DSP) chip functioning as the central processor unit (CPU) for the subscriber's cellular telephone unit, eliminating the microcontroller and other support chips. The integration provided is not a physical integration combining the DSP and microcontroller chips into a single chip architecture, but rather a logical (i.e., software) integration. A real time pre?mptive executive controls the execution of the different functions and the messaging between them. The amount of code that has to run on the DSP chip acting as the CPU is larger than the address space of the DSP chip, so the code memory is divided into banks with only one bank being activated at a time. It is the job of the real time executive to activate the banks as required to control the various functions.

Title: Spiral implant for organ pathways
Inventor: NEUSS MALTE
IPC: A61F2/06
Filed: 1992-02-12
Abstract: Abstract Spiral implant for organ pathways, in particular for blood vessels, which is formed from a primary spiral made of metal or a primary tube made of an elastic synthetic material whose anterior end is closed and whose cross-section at a distance of 0.5 to 2 mm from the other end of the primary spiral or primary tube is modified for a distance of 0.01 to 10 mm in order to make it possible to reposition the implant.  The force required to displace the primary shape on the guide wire serving as an inser-tion aid amounts to 0.5 N to 10 N.  The invention des-cribes an implant (1) which can be used in vascular surgery or vascular radiology in order to achieve selec-tive blood vessel occlusion.  Insertion of the implant (1) into a blood vessel is brought about by means of an insertion catheter (16), with the implant being held in a rectilinear shape by a guide wire (14) slid therein. After the implant has reached the correct position in the organ pathway (18) it assumes a pre-formed spiral shape on the withdrawal of the insertion wire from inside it, thereby ensuring fixation of the implant in the organ pathway.
