Title: Live spindle hub with inboard bearing retention
Inventor: DEANE ALASTAIR RUSSELL
IPC: B60B27/00
Filed: 1994-06-02
Abstract: ABSTRACT    An inboard bearing retainer for use in a vehicle wheel assembly having a live spindle.  The inboard bearing retainer includes a retaining nut adapted to be engaged to an outer diameter of the inboard end of the live spindle.   The nut including a flange which provides inboard retention and restrains inboard movement of the wheel bearing relative to the live spindle.   The nut also includes a surface which at  least partially defines the bearing seat for the wheel bearing.   The retaining nut is engaged by a locking assembly mounted to the spindle's inboard end so as to prevent disengagement of the retainer nut from the spindle.  In one embodiment, the locking assembly is a one-piece body having a bearing portion, a thrust washer portion and locking tabs which interferingly prevent disengagement of the retainer nut from the live spindle.

Title: Three-dimensional panoramic dental radiography method and apparatus which avoids the subject's spine
Inventor: WEBBER RICHARD L
IPC: A61B6/14
Filed: 1992-12-09
Abstract: THREE-DIMENSIONAL PANORAMIC DENTAL RADIOGRAPHY METHOD AND APPARATUS WHICH AVOIDS THE SUBJECT'S SPINE   Abstract of the Disclosure A panoramic dental radiography system projects multiple vertical, fan-shaped radiation beams through a subject's teeth and onto multiple detectors, with each fan-shaped beam avoiding the subject's spine. The radiographic source and radiographic detectors are rotated about a vertical axis, so that the detected radiation may be tomographically processed to produce a panoramic image of the teeth.  The multiple vertical fan-shaped radiation beams are projected on either side of the spine, to reduce the radiographic dosage to the spine and to prevent the spine from blurring the panoramic radiograph.  The resulting multiple projections can be tomosynthetically processed to produce a three-dimensional image of tissues of diagnostic interest, free of image artifacts produced by irradiation of the spine.

Patent CA-2145739-A1 (CA)
Inventor: SHANKWITZ HAROLD J
IPC: H02K29/00
Filed: 1995-03-28
Abstract: A brushless permanent magnet motor for use within a electric submergible pumping system is controlled without utilizing rotor position sensors, by sampling the voltage of the motor's windings. The operation of the motor is governed by control circuits that provide signals representative of the winding EMFs. The control circuits utilize an integrator, a offset corrector, and a crossover detector to simulate outputs received from Hall effect devices. Outputs from the control circuits are used to sequentially gate an array of commutation transistors to apply power to the different windings. These outputs are also used to develop a tachometer signal to regulate the speed of the motor, by controlling the supply voltage to the commutation transistors. Prior to starting the motor, the output bus voltage is permitted to rise from zero volts to a predetermined level. Then, the rotor rotates to a predetermined home position with regard to the stator. During this time, integrators are precharged to assist crossover detectors in establishing the initial timing relationship between the three motor phases. As the motor begins to rotate, the motor control is performed by detecting and processing winding EMFs, and operating the motor in a brushless D.C. mode.

Patent CA-2158129-A1 (CA)
Inventor: DOHERTY JAMES E
IPC: B25C1/08
Filed: 1995-09-12
Abstract: A system for controlling the energy output of a combustion-powered, fastener-driving tool, in which a fan is arranged to produce turbulence in a combustion chamber when the fan is driven, in which a direct current motor is arranged to drive the fan when a driving voltage is applied across the motor, and in which a battery provides a battery voltage not less than the driving voltage.  A voltage divider includes a settable resistance, either a potentiometer or two parallel, fixed resistances that can be alternatively selected, and is used to provide a setpoint voltage.  A comparator, an inverter, and a transistor switch are arranged to sample a voltage proportional to the rotational speed of the fan, to compare the sampled voltage to the setpoint voltage, to apply the driving voltage across the motor if the sampled voltage is less than the setpoint voltage, and to remove the driving voltage from across the motor if the sampled voltage is not less than the setpoint voltage.  The voltage divider also includes a permanently grounded resistance, two selectively groundable resistances, and two photoelectric switches, each including a phototransmissive diode and a photoreceptive transistor and being arranged to ground one of the selectively groundable resistances if a fastener between the phototransmissive diode and the photoreceptive transistor blocks phototransmission therebetween but not if the fastener does not block phototransmission therebetween.  The photoelectric switches can be thus used for discriminating among relatively short, intermediate-length, and relatively long fasteners.

Title: Ceramic fibres and methods, machines and compositions of matter for making the same
Inventor: STROM-OLSEN JOHN O
IPC: B22D11/00
Filed: 1994-05-27
Abstract: This invention relates to very fine, comparatively long, uniform surfaced and substantially round ceramic fibers and filaments, and apparatus, methods and compositions of matter for making same. Ceramic material of desired characteristics is rendered into a meniscus or convex molten apex of small horizontal diameter by such means as forming the ceramic feed-stock into a small diameter, solid rod (14) that is oriented vertically with its top end melted by a laser beam (22) or other nondisrupting, localized heat source, or using a synchronized vibrator or other physical energy means to produce a standing tip on the surface of molten ceramic contained in a crucible or other container. A narrow moving surface of adequate thermal, chemical and mechanical tolerance and heat transmission capability, such as the peripheral edge of a revolving molybdenum wheel (10) of small circumferential edge (12) width or a narrow endless belt, and the top surface of the molten apex (18) are brought into contact without the moving surface penetrating into the molten ceramic, and then backed away from each other. The ceramic, characterized, when molten, by its ability to wet the moving surface and by exhibiting melt viscosities that are conducive to free flowing as well as inherent cohesiveness, adheres to the moving surface, causing a strand (24) of ceramic to be formed, string-like and pulled away from the molten apex, and then to be cooled while adhering to the moving surface. As it does so, it "free-forms" into a smooth surfaced filament (26) of substantially uniform roundness because the surface tension of the outer surface layer of the strand then contracts, creating "hoop" compression forces on the mass of the still fluid ceramic which it surrounds, thus forming the desired filament, which is then stripped off and recovered from the moving surface.
