Abstract: A fluid-powered rotary actuator for providing rotary movement between first and second external members. The actuator includes a cylindrical body with first and second ends. The body is adapted for coupling to the first external member, and a shaft extending generally coaxially within the body and supported for rotation relative thereto. The shaft having an adjustable end limit of rotation relative to the body. The shaft has an end portion adapted for coupling to the second external member to provide rotational movement between the first and second external members. An annular body insert is positioned coaxial with the body and at least partially within the body at the body first end. The body insert is formed as a separate part from the body and is adjustably rotatable relative to the body to permit adjustment of the end limit of rotation of the shaft relative to the body. The body insert is restrained by the body against axial movement relative to the body during powered operation of the actuator. An end cap is securely attached to the body at the body first end and spaced axially outward of and away from the body insert to define a compartment therebetween. An adjustment member extends through an aperture in the end cap with an interior portion within the end cap compartment in position to engage the body insert and an exterior portion accessible from the exterior of the end cap compartment. The adjustable member is adjustably movable in the aperture to apply an adjustment force on the body insert to adjustably rotate the body insert relative to the body to a selected rotational position relative to the body in order to adjust the end limit of rotation of the shaft relative to the body. The adjustment member, when not being adjustably moved in the aperture, holds the body insert to prevent its rotation from the selected rotational position relative to the body. A piston is mounted within the body and is reciprocally axially movable therein in response to selective application of pressurized fluid thereto. A torque-transmitting annular member is positioned generally coaxially within the body for movement with the piston. The torque-transmitting member drivingly engages both a grooved sidewall portion of the shaft and a grooved sidewall portion of the body insert as the torque-transmitting member reciprocally moves within the body.

Title: Plates for dual plate check valves
Inventor: COOPER JAMES NICHOLAS
IPC: F16K15/03
Filed: 1994-11-30
Granted: 2005-01-18
Abstract: A metal plate (20) for a dual plate check valve. A central portio n (36) of a D-shaped plate (20) is reinforced such as by means of a raised area (36) on either or both sides of the plate to resist deformation when subjected to reverse pressure in the valve closed position, while the ends (35) of the plate are not reinforced.  This enables the valve plate to deform in a controlled manner to maintain or improve sealing engagement with a valve seat when the valve is subjected to reverse pressure in the valve closed position.
Patent CA-2179210-C (CA)
Inventor: BLODGETT JAMES RUSSELL
IPC: H04B7/10
Filed: 1996-06-17
Granted: 2000-04-11
Abstract: Disclosed is a cross-polarization cancellation apparatus and method particularly useful in a frequency reuse system, including a dual-polarized receiving system that receives a first electromagnetic signal having frequencieswithin a given frequency channel, which signal is transmitted from an external source at a first polarization. The receiving system also receives a second signal having frequency components within the given frequency channel which was transmitted at a second, different polarization. Received cross polarized energy of the second signal is cancelled by employing an antenna for receiving the first and second signals and for providing first and second antenna output signals containing received energy arriving at the antenna at the respective first and second polarizations. A novel circuit arrangement applies the antenna output signals to a combiner at an optimized relative amplitude and phase to substantially cancel the received cross polarized energy of the second electromagnetic signal.

Title: Apparatus, instrumentation and method for spinal fixation
Inventor: MICHELSON GARY KARLIN
IPC: A61F2/46
Filed: 1995-03-28
Granted: 2006-08-29
Abstract: A spinal fixation device for stabilizing one or more segments of the human spine and for preventing the dislodgement of intervertebral spinal fusion implants (40, 41), which remains permanently fixated once applied.  The staple member (12) is of sufficient length to span the disc space (D) between two adjacent vertebrae (V), to engage via essentially perpendicular extending projections (16, 17), the vertebrae (V) adjacent to that disc space (D).  A portion (14) of the staple member (12) interdigitates with an already implanted intervertebral spinal fusion implant (40) which itself spans the disc space (D) to engage the adjacent vertebrae (V). The spinal fixation device (10, 11) is bound to the spinal fusion implant (40) by a locking means (60). The spinal fixation device (10, 11) is for restraining the vertebrae (V) adjacent to the spinal fusion implant (40, 41) from moving apart as the spine is extended and also serves as an anchor for multi-segmental spinal alignment means (600) for aligning more than one segment of the spine.

Granted: 2000-05-23
Abstract: An adaptor (10) which allows a standard cartridge firing action to be used with a black powder muzzle loading gun (100) is described. The adaptor includes an insert (12) and a nipple (16) and is configured to be inserted into the barrel (108) of the gun adjacent the receiver (104). In use, a standard rifle cartridge casing (150) with a wall (150A) and with a head (150B) at one end containing a primer (152) is loaded into the receiver of the gun. Next, the cartridge casing is moved into the end (108A) of the barrel such that the casing extends into the center bore (14) of the insert and the nipple extends into the inside of the casing. When the gun is fired, the firing pin (114A) contacts the primer which ignites the black powder (118) which expels the projectile (120) from the gun. The ignition of the primer causes the wall of the casing of the cartridge to expand. The casing expands such that the casing is force fit and tightly held in the center bore of the insert. The expansion of the wall of the casing prevents blow back from the explosion from escaping past the adaptor and into the receiver of the gun.

Title: Network based multimedia messaging method for non-ccitt compliant switches
Inventor: MARKOWITZ ROBERT E
IPC: H04N7/10
Filed: 1997-03-12
Granted: 2000-11-14
Abstract: A method is disclosed for messaging multimedia calls with a non-CCITT  compliant switch when the intended recipient is unavailable. The method is used in connection with a telecommunication network which has an identified multimedia server (92). According to the method, multimedia calls from a caller, using a multimedia device (70) running a first application and a second application, are messaged when the called party is unavailable. The method involves initiating a multimedia call to the called party using the first application and determining that the multimedia call is an unanswered call using the second application. Using the second application, the first application is signalled to indicate that the multimedia call was unanswered.  In response to the signal, an X.25 packet message is sent from the multimedia device to the identified network based multimedia server. The multimedia device receives back a messaging address identifying a multimedia messaging server (100) from the network based multimedia server. A second multimedia call is initiated from the multimedia device (70) to the identified multimedia messaging server (100) using the first application and the messaging address.  The method then involves connecting to the multimedia messaging server indicated by the messaging address and recording a multimedia message on the network based multimedia messaging server.
