Title: Ensemble de soupape hydraulique
Inventor: KARABETSOS JEFFERY J
IPC: F15B13/02
Filed: 1996-09-11
Granted: 2002-07-02
Abstract: Ensemble de soupape hydraulique(10) configuré pour commander l'élévation et le fonctionnement de la chambre de coupe d'une tondeuse à moteur. L'ensemble de soupape comprend un boîtier (12) doté d'un tiroir (16) pouvant se placer en quatre positions, une position d'activation du vérin (A), une position neutre (B), une position de relâchement du vérin et de démarrage du moteur (C), et une position de marche du moteur (D). En position d'activation du vérin, la pression de refoulement est dirigée vers le vérin d'élévation de la chambre de coupe (28). En position neutre, le statu quo est maintenu et la pompe (20) se décharge au réservoir. En position de relâchement du vérin et de démarrage du moteur, la chambre de coupe, si elle est élevée, s'abaisse sous l'effet de son propre poids par relâchement de la pression du vérin de la chambre de coupe, et le moteur de la tondeuse (34) démarre à basse pression. En position de marche du moteur, le moteur est raccordé au circuit haute pression, et le vérin de la chambre de coupe continue de se décharger au réservoir.

Abstract: A wooden flooring strip having a top surface having a decorative finish and a base surface opposed to said top surface. The base surface has a multiplicity of closely spaced-apart scores extending into the flooring strip from the base surface transverse to the length of the flooring strip along substantially the entire length of the flooring strip to relieve stress and increase flexibility in the wood strip for more closely adhering to irregularities of a sub-floor. The flooring strip has substantially longitudinally-extending wood fibers in an area of the flooring strip between the scores and the top surface of the flooring strip which have been broken to an extent sufficient to relieve tension on the top surface of the flooring strip and to equalize tension on the wood fibers adjacent both the top surface and base surface of the flooring strip.

Abstract: A pen needle of the present invention includes an extender that is rotatably attached to a hub on the pen needle to set the pen needle to a desired injection length. The extender is rotated into multiple predefined positions using a shield that is removably mounted on the pen needle. Each predefined position for the extender corresponds to a predetermined injection length for the pen needle such that theextender covers a section of the pen needle not being used for the injection. After the shield has been used to rotate the extender into one of the predefined positions the shield is removed from the pen needle to expose the distal point of the pen needle so that the injection can be performed.

Title: A method of controlling initial power ramp-up in cdma systems by using short codes
Inventor: OZLUTURK FATIH M
IPC: H04B1/707
Filed: 1997-06-23
Granted: 2003-04-01
Abstract: A system and method of controlling transmission power during the establishment of a channel in a CDMA communication system utilize the transmission of a short code from a subscriber unit to a base station during initial power ramp-up. The short code is a sequence for detection by the base station which has a much shorter period than a conventional spreading code. The ramp-up starts from a power level that is guaranteed to be lower than the required power level for detection by the base station. The subscriber unit quickly increases transmission power while repeatedly transmitting the short code until the signal is detected by the base station. Once the base station detects the short code, it sends an indication to the subscriber unit to cease increasing transmission power. The use of short codes limits power overshoot and interference to other subscriber stations and permits the base station to quickly synchronize to the spreading code used by the subscriber unit.

Title: Polymerizable dental composition
Inventor: HINO KENICHI
IPC: A61K6/083
Filed: 1998-06-04
Granted: 2006-09-19
Abstract: A polymerizable composition for dental use, containing monomer (a) with a polymerizable olefinic unsaturated group, acylphosphine oxide (b), organic peroxide (c), tertiary amine (d) and aromatic sulfinic acid and/or a salt thereof (e). The polymerizable composition for dental use exerts excellent curability by any of photo-polymerization and chemical polymerization, having a good color for dental use, with less color change between prior to and after polymerization, and excellent light resistance, producing a cured product with a smaller thickness of the unpolymerized layer on the surface, having larger curing depth and excellent adhesion to teeth and metals and the like and great color fastness in hot water and in darkness. By taking advantages of these excellent properties, the polymerizable composition can effectively be used for utilities, for example as a bonding agent, a composite resin, an adhesive agent, a primer and an opaque primer and the like, for dental use.

Title: Incremental redundancy radio link protocol
Inventor: VAN NOBELEN ROBERT
IPC: H04L1/16
Filed: 1998-10-27
Granted: 2003-08-12
Abstract: A method and apparatus for sending blocks of data without any error correcting coding is described. If the block is received without an error then the next block of data is transmitted. If the block is received with an error, the receiving device sends a message requesting error correcting information. The transmitting device sends the error correcting information in specified increments until the receiving device can successfully decode the block without error. Once the block is received without errors, the next block of data is transmitted.

Granted: 2004-05-04
Abstract: A method and apparatus for placement of continuous pre-split, gel explosive in an elongated borehole or cavity. An anchor is attached to one end of a selected length of continuous -gel explosive. A suitable anchor is a flexible, plastic "pilgrim's hat" with a hole in the narrow, closed end. The size of the anchor depends on the width of the borehole; the flared skirt should be narrow enough to permit insertion of the anchor into the hole but wide enough to resist removal. One end of the explosive charge is pressed through the hole in the anchor. The remainder of the length of explosive is placed inside a tubular member, such as PVC pipe. The loaded pipe then is inserted into the borehole or cavity with the anchor leading. The pipe is used to push the anchor back into the hole to the desired depth. Then, the pipe is withdrawn.  The flexible skirt on the anchor engages the sidewall of the borehole and thus resists removal with the pipe. As the pipe is pulled out of the borehole, the explosive charge is left behind in a substantially linear arrangement. The explosive is detonated in a conventional manner.

Abstract: Conditioning apparatus for handling particulate material comprises a central frame and a plurality of spaced, annular troughs mounted to the central frame to support the particulate material. The troughs are arranged in a stacked configuration having successive pairs of upper and lower troughs with an uppermost trough for receiving the particulate material and a lowermost trough for discharging particulate material. Hydraulic cylinders or other suitable means are used to impart vibratory movement to the plurality of troughs to fluidize and advance the particulate material in a first direction on each of the plurality of troughs. A passage is formed through each trough for particulate material to fall from the upper trough of a pair to the lower trough.      The passage of the upper trough is non-aligned in a vertical plane with the passage of the lower trough such that particulate material falling from the upper trough is received on the lower trough to travel in the first direction over the distance of the lower trough before reaching the passage of the lower trough. A mixing surface is provided in each passage to promote tumbling and mixing of the particulate material which tends to ensure that all surfaces of the particulate material are exposed and available for the conditioning process. The conditioning apparatus finds particular application in drying of particulate material by passing drying gas through the fluidized material, or in filtering or scrubbing of gas by passing the gas through fluidized particulate material.
