Patent CA-2083580-A1 (CA)
Title: Shrinkable automotive clamp and protective coating
Inventor: SADR CHANGIZE
IPC: B29C49/04
Filed: 1992-11-23
Abstract: ABSTRACT OF THE DISCLOSURE           A clamp attaches a blow-molded drive axle seal to an automobile drive axle.   The seal has a generally tubular lip that can be inserted over the drive axle.  The clamp comprises a band of heat-shrinkable polymer material adapted to surround the circumference of the lip and to clamp the lip to the first member upon heating the band. A groove  around the circumference of  the drive  axle receives a pressure sensitive adhesive to bond the lip of the drive axle seal to the drive axle in a fluid sealing manner when the lip is clamped to the first member.  The clamp may be made integral with the lip of the drive axle seal by making the drive axle seal from said polymer material,  with  the body of  the seal  made non heat-shrinkable, and the lip made heat-shrinkable by suitable treatment,  e.g.  gamma radiation.   The heat-shrinkable polymer  material is also adapted to completely surround the drive axle seal and to mechanically interlock with the seal upon heating the material.   Since the material is capable of withstanding impacts by extraneous matter, it provides a protective coating for the seal.  The polymer material and the  seal may be  formed and  interlocked simultaneously in a blow molding process.

Patent CA-2090247-A1 (CA)
Title: Overlapped multilevel codes
Inventor: WEI LEE-FANG
IPC: H04L27/34
Filed: 1993-02-24
Abstract: A multilevel coded modulation scheme trellis encodes a portion of the input data and the resulting encoded stream is used to identify a particular one of a predetermined number of subsets of symbols of a predetermined signal constellation. The remaining input data is coded using a Reed-Solomon (RS) code whose output is used to select for transmission a particular symbol from the identified subset. In applications in which phase hits or other channel phenomena may cause the received signal points to be phase-rotated versions of the signal points that were transmitted, differential encoding is included in the overall coded modulation scheme. In different embodiments, the differential encoding/decoding and RS encoding/decoding are in different orders. In one such embodiment, overlapped multilevel codes are used to preserve the advantages afforded by taking a multilevel coding approach.

IPC: B64C25/42
Filed: 1994-03-02
Abstract: L'invention concerne un dispositif de freinage électro-hydraulique d'un train de roues d'aéronef.          Le dispositif comporte deux sources de pression hydraulique alimentant chacune un circuit hydraulique menant, par l'intermédiaire de platines de commande de freinage,  aux freins des deux groupes de roues. Un circuit relie,  par deux clapets navettes,  soit une électrovanne commandée électriquement par l'unité de pilotage, soit un double distributeur progressif commandé mécaniquement par les  pédales  de  frein,  à  une  entrée  des  platines.  Un deuxième circuit relie directement une électrovanne à une deuxième  entrée  de  chacune  desdites  platines.  Chaque platine inclut deux circuits internes symétriques ayant une servo-valve par frein concerné, qui sont interconnectés au niveau d'un clapet commandé respectif. En cas de panne sur un circuit, les servo-valves associées à l'autre circuit permettent alors un contrôle du freinage et de l'anti-patinage selon un mode tandem appairé, avec une reconfiguration automatique.

Title: Acoustic resonance arc stabilization arrangement in a discharge lamp
Inventor: DAKIN JAMES T
IPC: H05B41/24
Filed: 1994-03-03
Abstract: AN ACOUSTIC RESONANCE ARC STABILIZATION ARRANGEMENT IN A DISCHARGE LAMP                       ABSTRACT OF THE INVENTION An arc stabilization arrangement for a discharge lamp having a light transmissive arc tube containing a fill of gas excitable to a discharge state upon introduction thereto of a drive signal having a predetermined frequency associated therewith, includes a modulating arrangement effective for providing a modulating signal which is imposed onto the drive signal. The modulating signal has a frequency associated therewith which approximates the acoustic resonance of the gases within the fill, such modulating signal frequency being less than the frequency of the drive signal. In one embodiment of the invention the modulating arrangement is an amplitude modulating scheme effective such that a modulating amplitude of greater than about 5% of the amplitude of the drive signal is achieved. In yet a further implementation of the present invention, the frequency of the modulating signal is swept about a range of frequencies so that a varying acoustic resonance frequency can be encompassed by the modulating signal.

Title: Improved flue for fuel or wood burning appliance
Inventor: SINGER DOUGLAS
IPC: F23J11/02
Filed: 1994-04-20
Abstract: Disclosed is a flue section of very simple yet efficient structure which can be connected end to end to similar flue sections so as to form a flue for a burning appliance which may be located close to a flammable material without posing a fire hazard while showing, at the same time, superior heat-radiating quality. Each section comprises a cylinder and a deflector shaped to extend externally over part of the cylinder at a given distance away from the same to define therewith a laterally open air gap. The deflector is of the same height as the cylinder and is rigidly secured to the same. The remaining part of the cylinder that is not covered by the deflector may freely radiate heat. In the covered part theradiating heat is "stopped" at least in part by the deflector and channelled by the same laterally towards the uncovered part or exposed surface of the cylinder by air that is free to circulate in the air gap between the cylinder and deflector thereby. This reduces the temperature of the deflector in addition to distributing more heat into the room where the flue is located.

Title: Apparatus for the treatment of waste sludge
Inventor: BROUILLARD GAETAN
IPC: C02F3/30
Filed: 1994-05-16
Abstract: ABSTRACT OF THE DISCLOSURE             The invention relates to an apparatus for the treatment of waste sludge. The apparatus comprises as its main feature a vertically extending housing unit having a height/width ratio sufficient to provide separate zones in the housing unit, including a settling zone for thickened sludge, a mid-level buffer zone for waste sludge containing solid matter in suspension and a supernatant treatment zone for supernatant treatment. The housing unit also has an inclined bottom with a elope sufficient to cause a lateral and a gravity force to be exerted by the solid matter in the sludge along the inclined bottom to yield a thickened sludge at the settling zone of the housing unit and a supernatant liquid having a reduced solid content at the supernatant treatment zone of the housing unit.  The height/width ratio of the housing unit is important to provide the three zones referred to above by which treatment of the supernatant can be conducted in the supernatant treatment zone with minimal disturbance to the settling zone. The sloped bottom provides a geometry which improves sludge accumulation and evacuation, with minimal dilution.
