Title: Production process for a titanium alloy workpiece with modified hot griding and workpiece thereof
Inventor: CHAMPIN BERNARD
IPC: C22C14/00
Filed: 1992-05-13
Abstract: With this alloy having the composition (in mass %) Mo equivalent = 5 to 13 and Al equivalent = 3 to 8, Ti and impurities = the remainder, this process comprises a hot preliminary trimming of an ingot of the said alloy giving a hot blank, then a final trimming of at least a portion of this blank, preceded by a preheating above the real beta transition (2) of the said hot-trimmed alloy, the final trimming ratio (S/s) being higher than or equal to 1.5, and dissolving and then annealing treatments are then performed on the blank of an article obtained by final trimming. The process is characterised in that the said blank is cooled from its preheating temperature (8) to a temperature (9) of start of final trimming, situated between the beta transition (2) and the appearance of the alpha phase (7). 
<??>The invention also relates to the article obtained for a selected composition. The fabricated articles are intended, for example, for compressor discs or aircraft propulsion systems.
Patent CA-2069375-A1 (CA)
Title: Tilted fuel injector having a thin disc orifice member
Inventor: WOOD ROSS W
IPC: F02M61/18
Filed: 1992-05-25
Abstract: Abstract of the Disclosure A fuel injector has a thin disc orifice member through which fuel exits the injector for entrainment with combustion air. The thin disc orifice member has a centrally disposed dimple that contains the orifice pattern. The orifice pattern is asymmetrical about the axis of the dimple thereby enabling the injector to be tilted to a desired orientation for directing the stream from each orifice of the pattern toward a desired target zone. The ability to tilt a fuel injector in this manner enables a fuel injector to be disposed in the most favorable orientation with respect to the engine, for example reducing the protrusion height of the fuel injector above the engine.

Title: Highly reliable optical data system
Inventor: IMHOFF ANDREAS
IPC: H04B1/74
Filed: 1991-06-24
Abstract: Abstract Highly reliable optical data network, in which data are exchanged between an active central unit (CU1) and subscriber line units (DU1, DU2, DU3, ...) using the time-division multiplexing method.  The reliability is considerably enhanced by parallel connection of a back-up central unit (CU2). In order to permit a disruption-free switchover between the central units  (CU1,  CU2),  the latter have controllable delay devices (TDL1, RDL1, TDL2, RDL2), so that the delays of the signals to and from the subscriber line units (DU1, DU2, DU3, ...) can be matched with the aid of a special line unit(SDU).

Abstract: DeFord-Ely-Fearnot 1-1-14 Abstract of the Disclosure A catheter, system, and method for selectively ablating prostatic tissue about the prostatic urethra.  The catheter includes an elongated member having distal, proximal, and intermediate portions, the intermediate portion being shaped and sized for intimate contact with the prostatic urethra. The distal and proximal portions of the catheter include fixation and cooling balloons having an annular recess therein for positioning the internal and external sphincters therein and for maintaining the longitudinal position of the catheter in the prostatic urethra.  A thermally conducted, heat-emitting element  is positioned in the  intermediate portion  for  producing  a  thermally  conductive  heat distribution to ablate the prostatic tissue.  The catheter also includes irrigation and aspiration passageways therein for  communicating with the  interior of the distal  and proximal  cooling balloons.

Title: Spacer ring reservoir for magnetic recording disk lubricant
Inventor: GREGORY THOMAS A
IPC: G11B23/50
Filed: 1993-02-18
Abstract: SPACER RING-RESERVOIR FOR MAGNETIC RECORDING                DISK LUBRICANT                ABSTRACT OF THE DISCLOSURE      A lubricant reservoir system for a magnetic disk near contact data storage device, which rotates in unison with the disk assembly to replace lubricant depleted from the disk surface over the life of the device, includes reservoir chambers in disk spacers with lubricant metering provided by restricted passages or textured surfaces extending radially outward from the reservoir chamber while replacement air passages extend radially inward to replace dispensed lubricant.  The metered lubricant is delivered to the disk surface at a location where the surface confronting the disk is made compliant with the disk surface and the adjoining surface is beveled to form an angle of more than 90 degrees with the disk surface thereby preventing migration of lubricant away from the disk.  Nonwettable surfaces may be used in metering passages, air passages, and on some beveled surfaces to further control lubricant metering.  In operation, the high G forces induced by rotation cause lubricant to be metered to the disk while the same small metering passages function as a barrier when the disk assembly is not rotating.

Patent CA-2100842-A1 (CA)
Inventor: POIL JAMES E
IPC: A61F2/54
Filed: 1993-07-19
Abstract: A motion producing device in the form of a linear actuator, circular pump, or a robotic or prosthetic limb which functions to produce many kinds of useful work is provided.  The device includes a linear series of alternately spaced fixed and polarity reversible magnets.  The fixed and polarity reversible magnets may have more than one magnet assembled as a force unit of magnets of fixed polarity or reversible polarity which is surrounded by a rigid electrically insulating material and that carries rigid electrical conductors in the form of tubes.  Between each magnetic force unit is an elastic electrically insulating material allowing an expanding or shrinking of the distance between the magnetic force units in accordance with the polarity reversal of the reversible  magnetic force units.  The elastic expansion or contraction material carries flexible elastic tubes that connect up with the rigid tubes to hold a current carrying electrolyte to carry an electrical current from  a D.C. battery to the magnets when they are electromagnets.          Various types of guides are used to prevent lateral movement of the magnets.  A second embodiment also has magnetic force units of the fixed and reversible polarity type but has slideable electrical contacts in an external side guide and therefor requires no electrolyte or tubes.  A further modification utilizes the original rigid tubes and provides guide rods as slideable electrical contacts to slideabley engage the rigid tubes which are metal.  Again the disposing of the elastic flexible nonconductive tubes in the elastic nonconductive filler material between adjacent magnets is possible.

Patent CA-2101394-A1 (CA)
Inventor: BARNUM THOMAS G
IPC: F16K11/16
Filed: 1993-07-27
Abstract: A mixing valve according to the invention allows fluids such as hot and cold water to flow through a pair of inlet ports, mix together and then exit through an outlet port.  A check valve in each inlet allows the incoming fluid to flow in a forward direction, but prevents any reverse or crossover flow.  An adjustable stop, positioned intermediate the valves, regulates the extent to which each valve can open to provide a desired mixing ratio of fluids, and can also be used to close one of the check valves.  An actuator connected to the adjustable stop permits manual control of the mixing ratio.

Filed: 1993-12-09
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a method of finely polishing an optically transparent surface with a polishing liquid containing abrasive particles.  The polishing mixture, while subjected to ultrasonic agitation, is contacted with an optically transparent surface under conditions effective to polish finely that surface.
