Inventor: CASTRO MICHAEL
IPC: A61F2/28
Filed: 2003-03-17
Abstract: An apparatus for facilitating fusion of adjacent vertebral portions includes an implant member dimensioned for positioning between adjacent vertebral portions and defining a longitudinal axis. The implant member includes an outer member having an exterior wall defining an internal cavity and a clip receiving opening subtending a peripheral portion of the exterior wall, an inner member telescopically received within the internal cavity of the outer member to permit relative movement of the outer and inner members and a locking clip dimensioned for at least partial reception within the clip receiving opening of the outer member. The inner member includes an exterior wall defining an internal cavity and having a plurality of locking slots spaced along the longitudinal axis. The locking clip includes a clip base and locking clip legs depending from opposed ends of the clip base. The locking clip legs are dimensioned for reception within corresponding locking slots of the inner member to selectively secure a relative position of the outer and inner members to establish a predetermined height of the implant member.

Abstract: An adaptor (10) which allows a standard cartridge firing action to be used with a muzzle-loading firearm (100) is described. The adaptor includes a breech plug (12) and a nipple (16) and is configured to be inserted into the barrel (108) of the firearm adjacent the receiver (104). The breech end (16A) of the nipple (16) has a conical shape. In use, a standard ignition cartridge (150) with a casing (150A) and a head (150B) with a primer (154) mounted in the flash hole (152) in the head are loaded into the receiver of the firearm. Next, the ignition cartridge is moved into the breech end (108A) of the barrel such that: the casing extends into the center bore (14) of the breech plug and the breech end of the nipple extends into the end (152B of the flash hole in the head of the cartridge and is adjacent the primer. When the firearm is fired, the firing pin (114A) contacts the primer, which ignites the primer. The spark from the primer travels directly through the center bore of the nipple through the center openings of the propellant pellets (118) which ignites the propellant pellets which expels the projectile from the firearm.

IPC: B25C1/06
Filed: 2001-12-21
Abstract: Disclosed and taught is a novel drive mechanism for a cyclic operating tool employing an energized flywheel (45) to provide the necessary energy to perform a working cycle. The drive mechanism disclosed is particularly usefu l in hand tool applications such as a hand held nailing machine. The flywheel may be energized by a corded or battery powered motor (42). The herein disclosed mechanism teaches a novel pair of ball ramp cam plates (52, 54, 56 , 58) wherein a first pair of ball ramps (56, 58) cause an initial engagement of a clutch with the energized flywheel whereupon rotation of the clutch (35) causes activation of a second pair of ball ramps (56, 58) which affect compression of a spring which acts to increase the pressure applied to the clutch thereby assuring a slip free engagement between the clutch and the flywheel throughout the working cycle of the drive mechanism. Upon completio n of the drive mechanisms working cycle, the second pair of ball ramp cam plat es further act to disengage the clutch from the flywheel may dissipate the unus ed kinetic energy remaining within energy remaining within the flywheel as the drive mechanism returns to the start position.

Inventor: STEFFENS RALF
IPC: B23G1/32
Filed: 2002-01-12
Abstract: The invention relates to the production of screw pump rotors comprising a pitch and/or depth of teeth which can be modified along the axis of the rotor.  By means of a simple profiled machine tool (7), a first part of the profiled flank contour is clearly defined along the rotor axis (8) by means of its specific tool guide mechanism, and is then produced in a definitive manner.  The remaining second part of the profiled flank contour is then determined according to the rolling movement of the pair of rotors according to the first part of the profiled flank contour carried out by the tool, by means of an approximation which is as precise as possible. It is thus possible to obtain transversally different profiled contours according to the pitch and/or depth of teeth which can be modified along the axis of the rotor. A disk milling cutter is selected to be used as a profiled machine tool.

Title: Apparatus for and method of forming seals in fuel cells and fuel cell stacks
Inventor: MAXSON MYRON THIMOTHY
IPC: H01M8/02
Filed: 2002-05-15
Abstract: A sealing technique is provided for forming complex and multiple seal configurations for fuel cells and other electrochemical cells. To provide a seal, for sealing chambers for oxidant, fuel and/or coolant, a groove network is provided extending through the various elements of the fuel cell assembly. A  source of seal material is then connected to an external filling port and injected into the groove network, and the seal material is then cured to form the seal.    There is thus formed a "seal in place", that is robust and can be bonded, where possible, to individual elements of the fuel cell assembly. This avoids the difficulty, labor intensive cost and complexity of manually assembling many individual gaskets into complex groove shapes and the like. The seal material can be selected to be compatible with a wide variety of gases, liquid coolants and the like.
