Inventor: REIFENHAEUSER HANS
IPC: D04H3/16
Filed: 1987-11-09
Granted: 1991-07-16

Patent CA-1339234-C (CA)
Inventor: MATLACK ALBERT SHELTON
IPC: C08G61/06
Filed: 1987-11-30
Granted: 1997-08-05
Abstract: This invention teaches the preparation of crosslinked copolymers of dicyclopentadiene and higher oligomers of cyclopentadiene.  The copolymers comprise about 40 to 95% by weight, based on total copolymer weight, of repeating units derived from dicyclopentadiene and about 60 to 5% by weight of repeating units derived from higher cyclopentadiene oligomers.          The preparation of the copolymers of this invention does not require preparation of expensive comonomers.  The higher cyclopentadiene oligomers are conveniently and inexpensively prepared by heat treatment of dicyclopentadiene.  By proper selection of heat treatment conditions, the desired mixture of dicyclopentadiene and oligomers can be prepared in situ and it is not necessary to effect any separation of the oligomers from dicyclopentadiene.  Such copolymers are characterized by having significantly higher heat distortion temperatures and glass transition temperatures than crosslinked dicyclopentadiene homopolymer.

Title: Narrow accessway sewage collection tank assembly, remote operated quick connect-disconnect coupling and system using the same
Inventor: GRACE RICHARD C
IPC: E03F5/22
Filed: 1988-12-29
Granted: 1993-03-02
Abstract: ABSTRACT A narrow-accessway sewage collection tank assembly and system using a remote operated, two-part, slide coupling for supporting a sewage pump within an enlarged collection tank for installation outside below normal ground level of residences, commercial and industrial buildings for use in the collection and disposal of sewage produced in the buildings.  The narrow accessway tank system can be installed with minimum cost and impact on the environment while maintaining proper operating conditions, good scouring of the collection tank bottom and facilitating below ground installation and subsequent maintenance and servicing of the sewage pump unit from the surface.  The system comprises an enlarged sewage collection tank to be planted below level in the ground near a building and connected to suitable gravity drain conduits interconnected between the facility to be serviced and the collection tank for collecting raw sewage. The sewage pump unit comprises a sewage grinder pump physically supported within the enlarged collection tank for grinding and pumping the liquid sewage including any entrained solids out through a pressure sewage discharge outlet conduit to a suitable sewage disposal installation such as a drain field.  A narrow-access passageway enclosure is physically supported on top of the collection tank and provides access to the sewage grinder pump unit within the interior of the tank.  The narrow-access passageway is of sufficient cross-sectional dimension to allow free passage up and down for the sewage grinder pump unit, but is insufficient in cross section to accommodate passage of human beings or to accommodate a pipe guide system of conventional construction.  A two-part, quick connect-disconnect slide coupling is provided for physically supporting the sewage grinder pump unit within the collection tank properly positioned relative to the bottom to assure proper scouring and prevent build-up of solids, but allows ready removal of the sewage grinder pump unit from the surface by a serviceman using a remotely operated tool to decouple the grinder pump unit via the quick connect-disconnect slide coupling and withdrawing it upwardly through the narrow-access passageway enclosure to the surface for service and maintenance or replacement.

Granted: 1994-09-06
Abstract: MONITORING AND FAULT PROTECTION OF HIGH VOLTAGE SWITCH YARDS                          ABSTRACT    The currents flowing through high voltage conductors in a network or switchyard are monitored by magnetic field sensors in the form of air-cored epoxy-filled coils which are electrostatically shielded by discontinuous shields. The magnetic field sensors are located a safe working distance away from the conductors being monitored to remain substantially at earth potential and are orientated to maximize the magnetic field influence from the conductors being monitored.  The value of the magnetic field detected by the sensors are sampled instantaneously and the sampled value is processed, having regard to calibration and cross linking effects of the network being monitored to calculate the instantaneous current flowing through the network.

Abstract: Abstract The present invention relates to a retro-reflective laser scanning system for reading indicia having portions of different light reflectivity.  The scanning system is comprised of a laser diode which is operative for emitting a laser beam at a wavelength which is at least marginally visible to the human eye.  An optical means is provided for optically forming and directing the laser beam along an optical path to the indicia.  A scanning unit is provided for scanning the indicia in a scan across the same.  The returning portion of the reflective laser light has a variable intensity over the scan.          A sensor is provided for detecting the variable intensity of the returning portion of the reflected laser light over a field of view.  The sensor generates an electrical signal indicative of the indicia being read.  The sensor has a generally rectangular detector aperture to minimize interference between ambient light and the returning portion of the reflected laser light.  The detector aperture has a long side extending along the scanned direction thereby forming a generally non-circular field of view.  A unit is provided for adjustably positioning the laser beam to lie within the non-circular field of view.

Title: Method and apparatus for controlling the growth of non-osseous non-cartilaginous solid connective tissue
Inventor: LIBOFF ABRAHAM R
IPC: A61N2/04
Filed: 1989-09-27
Granted: 1994-12-20
Abstract: An apparatus and method for regulating the growth of connective tissue proper in vivo are provided. The apparatus includes a magnetic field generator and a magnetic field detector for producing a controlled, fluctuating, directionally oriented magnetic field parallel to a predetermined axis projecting through the target tissue. The field detector samples the magnetic flux density along the predetermined access and provides a signal to a microprocessor which determines the average value of the flux density. The applied magnetic field is oscillated at predetermined frequencies to maintain a preselected ratio of frequency to average flux density. This ratio is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field as the composite magnetic flux density changes in response to changes in the local magnetic field to which the target tissue is subjected. By maintaining these precise predetermined ratios of frequency to average magnetic flux density, growth characteristics of the target connective tissue proper are controlled.
