Title: Cyclic sulfide compound, polymerizable compositions for optical products and optical products formed thereof
Inventor: KANESAKI HIROYUKI
IPC: C07D339/06
Filed: 1993-03-23
Granted: 2001-02-20
Abstract: The present invention provides a cyclic sulfide compound represented by a general formula (I)   (where R1 represents -CH2-CH2-, -CH2-CH2-CH2-, -CH2-O-CH2-, -CH2-O-, or -CH2-S-).      According to this invention, a novel cyclic sulfide compound which gives high refractive index and high Abbe number can be obtained. The polymerizable compositions for manufacturing optical products with this compound as their main component can be readily molded into plastic lenses which give superhigh refractive indices and high Abbe numbers or those which give high refractive indices and high Abbe number with low sp.grs. in addition thereto. The castings obtained from said polymerizable compositions are useful as plastic lenses for glasses, manifesting optical uniformity and being excellent in processability, transparency, and thermal, impact and light resistance. Further these polymerizable resin compositions are usable preferably as such optical products as prisms, optical fibers, optical disc substrates, color filters, or infrared absorption filters.

Title: Drawbar connection
Inventor: DAWSON RICHARD W
IPC: B61G9/24
Filed: 1993-04-26
Granted: 1999-03-16
Abstract: An improved drawbar connection for railroad cars reduces slack between cars and results in improved train handling.  The drawbar connection fits in a standard draft gear pocket and utilizes a standard yoke, standard follower and standard coupler pin, thereby permitting the application of drawbars with minimal structural modification to cars originally equipped with conventional couplers.  The usual draft gear is replaced by a filler which is relatively rigid.  The filler includes a follower block, a wedge, a filler block and may include a mini-draft gear having a maximum travel of about one-half inch.

Granted: 1999-03-16
Abstract: A system and method for controlling the clutches in a vehicle powershift transmission.  The control system includes a microprocessor which periodically executes an algorithm and which has a memory in which is stored a sequential set of time reference values and a sequential set of pressure values.  The control system applies to each oncoming element a fill pressure pulse for fill periods which are unique for each element.  The control system determines shift time values, subsequent to filling of the control elements, as a function of the fill period.  The control system applies pressure signals to the control elements at times represented by the shift time values which are unique for each element. The control system determines, subsequent to a realignment time, realignment shift time values which are the same for all of the control elements.  The control system also applies pressure signals to the control elements subsequent to the realignment time, at times determined as a function of the realignment shift time values.

Granted: 1998-04-28
Abstract: Un compresseur (50) possède un actuateur (52) pour mouvoir le piston (58) dans un cylindre de compression (56). Un dispositif électromagnétique (76) comporte un noyau (77) et une bobine (80). Le noyau comporte une surface (104) et un canal (90). La bobine est disposée dans le canal. L'armature à déplacement axial (78) est en liaison mécanique avec le piston animé d'une course axiale avec milieu et fin de course. La surface (94) de l'armature est dimensionnée pour s'aligner avec la surface de l'électro-aimant lorsque le piston se trouve au sommet de sa course. Un ressort primaire (84) situé à l'une de ses extrémités, s'oppose au mouvement axial de l'armature dans une première direction. Un ressort secondaire (86), situé à l'autre extrémité de l'armature, s'oppose au mouvement axial de l'armature dans une direction opposée. Les ressorts contraignent l'armature à un mouvement de résonnance à une fréquence prédéterminée. L'application de courant en milieu de course du piston maintient la fréquence de résonnance, et permet d'éliminer les pertes dues au frottement et les forces de compression. Le montage de deux actuateurs  dos-à-dos crée un compresseur à deux pistons.

Information from the emulated CO station terminals is mapped into existing system structures where such structures are available and compatible with the information from the emulated terminal.
Patent CA-2147456-C (CA)
Inventor: KOSTEK SERGIO
IPC: G01V1/44
Filed: 1995-04-20
Granted: 2006-06-06
Abstract: The present invention is directed to sonic logging while drilling. A  transmitter and at least one receiver are mounted on a drill collar far performing sonic investigations of the formation traversed by a borehole. It has been discovered that a drill collar has a natural stop band or notch where acoustic energy propagating in this frequency range is severely attenuated. Thus, to reduce drill collar acoustic coupling, the transmitter is operated within this natural stop band of the drill collar. An imperforate stop band filter is also included between the transmitter and receiver to enhance the natural stop band. The transmitter is mounted transverse to the longitudinal axis of the drill collar, and is preferably mounted within means that reduce drill collar acoustic coupling. The transmitter preferably includes a material whose acoustic response is more favorable along its longitudinal axis relative to its radial axis, thereby directing the acoustic energy into the formation rather than the surrounding drill collar. Received acoustic energy waveforms are electronically processed to reliably detect, in the presence of drilling noise, those acoustic signals which are produced by the transmitter and transmitted through the formation.

Title: Vascular incisor/dilator
Inventor: LARY BANNING GRAY
IPC: A61M29/02
Filed: 1995-09-07
Granted: 2007-03-13
Abstract: A device and method for clearing a stenosis in a vessel of a patient requires a probe catheter having a cone-shaped probe at its distal end. The probe has a distally diminishing taper and also has a plurality of blades which are mounted on the probe and longitudinally aligned with the probe catheter. Advancement of the probe through the vessel to the stenosis can be accomplished either over a prepositioned guidewire or through a prepositioned guide catheter. At the stenosis, the probe with mounted blades are reciprocally moved back and forth across the stenosis to incise and dilate the stenosis and, thus, clear the stenosis. Movement of the probe across the stenosis can be facilitated by selectively activating a rigidizer which is located on the probe catheter immediately proximal to the probe. Additionally, a balloon can be mounted on the probe catheter proximal the probe member and selectively inflated at the stenosis after the stenosis has be incised and dilated.

Granted: 1999-02-09
Abstract: A method and apparatus for controlling the speed of a multi-phase, brushless DC electrically commutated motor (ECM). Voltage is commutated to the windings of the ECM based on rotor position information derived from back EMF or Hall effect sensors. The application of the commutating voltages is arranged such that the voltage applied to the windings always leads the back EMF generated in the windings by aselected constant lead angle. The speed of the motor is then controlled by pulse width modulating (PWM) the voltage applied to the windings of the ECM.

Granted: 2008-06-03
Abstract: An improved electrical ceiling box comprising a top portion bounded by a peripheral side portion, with a pair of diametrically opposed ear lugs rigidly secured to the side portion. Each ear lug has a pair of ears integrally formed therewith extending inwardly into the interior cavity of the box. A first ear fits within a recess formed in the bottom edge of the box, while a second ear extends through a slot formed in the side portion of the box. The second ear has a mounting hole formed therein adapted for threaded engagement with a self-tapping screw, while the first ear has a receiving hole formed therethrough for supporting the distal end of the screw. In a preferred embodiment, the box has a substantially hexagonal configuration. In an alternative embodiment, the box has a circular configuration and is shallower, thereby eliminating the need for a pair of slots for receiving the first ears. Preferably, the ear lugs are formed from a heavier gauge material than the remainder of the box for improved strength and resistance to breakage from fatigue.
