Abstract: Auxiliary suction equipment for performing a medical operation. A flexible mat partitions off an organ to be operated on from other internal organs, and a suction tube removes blood and body fluid caused by the operation. The insulating qualities of the mat allow the procedure to be performed with the protection of the organ muscle by a local low-temperature method in order to control the metabolism of the organ to be operated on. The mat can be provided with a passage to introduce a fluid for controlling the temperature of the mat surface.

Abstract: A vehicle suspension includes a variable damping effectiveness type shock absorber, which has an actuator and according to selective actuation thereof can be set to first, second, or third conditions which respectively cause the shock absorber to provide minimum, medium, or maximum damping effect.

Abstract: A resilient bushing having an inner sleeve, an outer sleeve disposed around the inner sleeve in co-axial and radially-spaced relation thereto, and a cylindrical resilient member interposed between the inner and outer sleeves. The bushing comprises an intermediate sleeve substantially embedded in the cylindrical resilient member in co-axial relation thereto. The intermediate sleeve has a radially outward flange at one or both of its axial ends.

Abstract: A shock and vibration absorbing mounting includes a first retainer member and a second retainer member. These retainer members are mutually coupled together and are spaced apart from one another, and have respective first and second surfaces which oppose one another. A third retainer member is located between the first and second retainer members, and has a third surface which opposes the first surface of the first retainer member and a fourth surface which opposes the second surface of the second retainer member. A first resilient member is provided between the first surface of the first retainer member and the third surface of the third retainer member, and a substantial amount of play is left between the first and the third surfaces of the first and third retainer members.

Abstract: A supply voltage monitoring device for an automotive battery comprising an average voltage generation circuit for generating the average voltage of the supply voltage of a battery as a power source for various equipment on board an automobile, a Zener diode conducting when the output voltage of the average voltage generation circuit exceeds the prescribed value, a first transistor connected between the Zener diode and the average voltage generation circuit, a second transistor controlled by the conducting Zener diode, a capacitor controlled for charging and discharging by the output of the second transistor, third transistors controlled by the output voltage of the capacitor, and a light emitting diode controlled for the light emitting state or the non-emitting state by the second transistor or the third transistors, and characterized in that the device is constructed to monitor the supply voltage of the battery by the light emitting state or the non-emitting state of the light emitting diode.

Abstract: A hand-operated hydraulic compression tool for compressing a metal connector about a plurality of wires to be connected. The tool is adapted to make both parallel and butt-type connections of the wires. The tool includes a pressure relief valve for limiting the maximum pressure to be applied to the connector. The valve is removably installed in a cavity of the tool body for facilitated servicing. The tool further includes control structure for releasing the pressure upon completion of a forming operation, the flow passage for the returning hydraulic fluid utilizing a portion of the body cavity receiving the pressure regulating valve.
