Abstract: A cutting/scraping tool is disclosed, comprising a housing (22) defining a longitudinal axis (A), a transverse chamber (30), and a blade chase (28) adjacent a forward end of the housing. A cartridge (32) is releasably retain ed within the chamber by detent lugs (36B) extending laterally from an outer surface of the cartridge in frictional engagement with a plurality of complementary detent recesses (36A) positioned on the housing. A blade (40) within the cartridge is in aligned registry with the blade chase (28). A deflector (52) is positioned beneath the blade. A transport mechanism (42) i s slidably mounted on the housing for substantially longitudinal movement between forward, intermediate and rearmost positions. An actuator (44) projects from the housing to effect said sliding movement of the transport mechanism. The transport mechanism has a flexible, resilient tongue portion (42A). A tab (46) is formed on the tongue portion within the housing adjacen t a forward end of the transport mechanism. The transport mechanism is rearwardly removed from the cartridge at the rearmost position. Sliding movement of the transport mechanism from the rearmost position to the intermediate position causes the tab (46) to enter the cartridge beneath the  blade, and be deflected upwardly by the deflector, to carryingly engage a socket positioned on an underside of the blade. Sliding movement of the transport mechanism from the intermediate position to the forward position causes the tab to carry the blade from the cartridge to project in an operative position from the blade chase, so as to present a sharpened edge (40B) of the blade for use.

Abstract: The present invention provides a designated master communications device which is adapted to act as the master under all circumstances, together with a method of enforcing a master-slave relationship. This is achieved by having the designated master communications device detect the presence of any other communications device. When this is achieved, the communications device establishes a wireless connection with the other communications device such that the designated master communications device acts as the master. Any subsequent communication is then performed via this established wireless connection. This ensures that the designated master communications device operates as the master with any other device fitted thereto operating as a slave.

Abstract: This invention relates to an almost invisible method of fastening and unfastening sunglass frames to eyeglass frames. By the use of elongated slots molded into the back of the eyeglass frames, on each side of the nose bridge and just above the nose rests. Guides above the slots that follow the contour of the eyeglass frame lead into them. Friction spring arms insert into the slots and lock the sunglasses in place. The friction arms are an extension of a spring that applies pressure to the sunglass nose bridge inside the spring and bridge housing and allows the sunglasses to flip up and or serve as a visor by staying in any position the user desires from 0 to 180 degrees.

Title: Methods for restoring the heat transfer coefficient of an oligomerization reactor
Inventor: EWERT WARREN M
IPC: C07C2/08
Filed: 2000-12-21
Abstract: The specification discloses a method for cleaning an oligomerization reactor after making a higher olefin in the reactor. An olefin is reacted in the presence of a catalyst comprising an aluminum alkyl to form an olefin reaction product. For example, ethylene can be trimerized in the reaction to produce 1-hexene. The reaction also causes a co-product residue of the catalyst to form on the interior surface of the reactor. The interior surface of the reactor is then contacted with an alcohol under conditions effective to remove at least a substantial amount of the catalyst residue from the interior surface of the reactor. The catalyst-removing step can be carried out by combining an alcohol with the process medium used in the reactor. The combined medium can be used to remove both the accumulated polymer co-product and the accumulated catalyst residue from the reactor.

Title: Resilient cutting blades and cutting devices
Inventor: DETORRE ROBERT P
IPC: B26D1/24
Filed: 2002-09-16
Abstract: Steel reinforced tire fabrics are cut with long rigid bar blades, circular disc blades sand disc and anvil blades. All of these blades may have an open relatively deep slot spaced close to the cutting edge that creates a resilient cantilevered spring element that includes the cutting edge. In response to cutting forces, the spring element will deflect and form a concave crossover area that improves cutting. A supporting material, particularly a precompressed supporting material, such as a precompressed or stretched polyurethane strip may be inserted into the slot. The supporting material limits or reduces the deflection of the spring element so that the yield strength of the spring element is not exceeded and it returns to its original position when the forces are removed. A precompressed supporting material exerts an outward force on the spring element. A polyurethane strip may be precompressed by stretching it before it is inserted into the slot. Two overlapping blades are used to cut the tire fabric, one or both can have the resilient spring features. More than one slot may be provided in a blade so there is more than one spring element in one blade. The blades can be used to cut other materials.

Title: Capless refueling assembly with dampened flap door and baffle
Inventor: BEAULNE MICHAEL A
IPC: B60K15/04
Filed: 2002-10-03
Abstract: A fuel refilling assembly for transferring fuel from a nozzle to a fuel tank  of a motor vehicle. The fuel refilling assembly includes a fuel filler neck extending out from the fuel tank. The fuel filler neck has a tank end disposed adjacent th e fuel tank and a distal end. A housing is fixedly secured to the distal end of the fuel  filler neck. The housing defines an opening for receiving the nozzle therethrough. A flapper door is pivotally secured to the housing and is movable between a closed position  for preventing access from the housing to the fuel filler neck, and an open position for allowing the nozzle to transfer fuel to the fuel tank via the fuel filler neck. A dampener mechanism abuts the flapper door. The dampener mechanism dampens th e movement of the flapper door as the flapper door moves from the open positio n to the closed position upon the removal of the nozzle. As a result, excess fuel lef t in the housing after the nozzle has been removed therefrom is allowed to flow into the fuel filler neck prior to the flapper door moving to its closed position.
