Abstract: A multiplane TEE probe is provided for the imaging and diagnosis of multiple scan planes from within a cavity of the body. The probe includes an articulation section formed of a plurality of interconnected links. The articulation section is controlled from the handle of the probe, with the articulation limit stops located in the handle. The articulation section may be locked in a given bent position, but the lock will be overcome by the force of the esophagus against the transducer tip if the probe is withdrawn in a locked and bent position. When the articulation section is locked an indication signal is displayed on the handle of the probe and on the display of the ultrasound system.

Abstract: A multiplane TEE probe is provided in which rotation of the ultrasonic transducer is motor controlled. The motor is controlled to rotate the transducer either clockwise or counterclockwise, and at either a high rotational speed or a low rotational speed. The motor is also automatically controlled to drive the transducer to a predetermined home position. The transducer tip of the probe is detachably connected to the gastroscope tube. An aluminum sheet is embedded in the acoustic lens in front of the transducer to dissipate heat which accumulates in the lens. The gastroscope tube includes an articulating section formed of a plurality of matching cylindrical links which form alternating pivot axes from one link to the next. The pivot range of each link with respect to an adjoining link is controlled by opposing limit stops orthogonally located with respect to the pivot points of the links.

Abstract: A razor blade assembly is provided having a molded plastic body member with a guard member mounted thereon. The body member comprises wall structure defining a pair of slots for receiving a blade means, and forming a support means on which the blade means rests. The blade means comprises a pair of cantilever spring portions formed in the blade means got contacting the support means when the blade means is disposed for slidable movement in the slots whereby the blade means is resiliently mounted in the body member.

Abstract: A safety razor comprises a pivotal cap member which in a first position is effective to obscure the cutting edge of the blade or blade members to protect the cutting edge from contact with other objects. The cap member when pivoted to a second position exposes the blade cutting edge and positions a skin engaging guard surface adjacent the blade cutting edge to provide a desired shaving geometry.

Abstract: A two-stage fuel regulator, adapted for operation in any orientation and over a wide temperature range, which includes a pressure limiter, a fuel vaporizer, a low pressure cutoff and an on/off switch. The first stage includes an inlet from a fuel storage tank where the fuel is maintained in a two-phase system of liquid and vapor. The tank inlet opens to one side of a diaphragm having a throughgoing hole surrounded by an annular valve face. A space on the other side of the diaphragm defines an expansion chamber. By adjusting the biasing force with which the valve face abuts a valve seat, the expansion chamber pressure may be maintained to be less, by a predetermined pressure difference (e.g., 1 psi), than the tank pressure, whereby vaporization of all fuel in the expansion chamber is assured. Additionally, whenever the tank pressure drops below the predetermined pressure difference (e.g., when the fuel supply is low or in a cold environment), passage of fuel into the expansion chamber is prohibited.

Abstract: A hand-held lighting device, including a housing, an elongated cantilevered member anchored within the housing, and a mantle mounting disposed at the unanchored end of the cantilevered member, the cantilevered member including a first member, a second member coaxially and slidingly mated with the first member and a spring for biasing relative coaxial movement between the first and second members. A knuckle socket is disposed between the unanchored end of the cantilevered member and the mantle mounting for canting a portion of the cantilevered member in response to transverse shock forces.

Abstract: A hand-held lighting device employing an incandescent mantle as a light source and having a pilot burner fixedly mounted within the lighting device housing adjacent a mantle mounting, the pilot burner being aspirated to promote efficient combustion and reduce the accumulation of soot on the interior of the housing. The pilot burner is ignited by an ignition assembly, such as a flint wheel, which is actuable from outside of the housing.

Abstract: A gas turbine power plant has a compressor stage and a turbine stage with an annular combustion stage therebetween. Each of the contra-rotatable compressor rotors is connected to one of the contra-rotatable turbine rotors by an elongated hollow cylindrical shaft concentric with an axially extending fixed shaft to form an integral unit. The units are operably connected by differential gearing mounted on the fixed shaft just in rear of the nose of the engine at the air intake end of the housing.
