Abstract: A safety medical connector includes a composite inner pipe, a first resilient element, a sealing element, and a housing. The first resilient element hermetically seals the entrance of the housing, and the sealing element hermetically seals the exit of the housing; hence, thanks to the double hermetic seal structures, the safety medical connector is leakproof and airtight. When in use, part of the composite inner pipe is secured and stationary, thereby enhancing structural stability.

Abstract: A safety medical connector includes a composite inner pipe, a first resilient element, and a second resilient element. The first resilient element hermetically seals the entrance of the composite inner pipe. In operation, the first resilient element is pushed aside such that the entrance of the inner pipe opens. After use, the second resilient element drives the composite inner pipe and the first resilient element to restore position. Hence, the safety medical connector advantageously features reduced liquid residue and enhanced structural stability.

Abstract: An apparatus comprises a first number of splines located near a first end of a first joint section and a second number of splines located near a second end of a second joint section. The first number of splines extends in an axial direction of the first joint section and spans a circumferential surface of the first joint section. Each of the first number of splines has a base, a tip, and a pair of flanks that extends from the base to the tip and forms an acute angle. Each of the first number of splines are configured to be received between adjacent pairs of splines in the second number of splines as the first end of the first joint section and the second end of the second joint section are joined.

Abstract: In a vibration damper of a turbomolecular vacuum pump, a vacuum tightness function and a vibration damping function are both performed by one ore more toroidal rings made of an elastic material. The elastic rings assume a resting configuration while the vacuum pump is not operating and the damper is at atmospheric pressure, and they assume a compressed configuration while the vacuum pump is operating and the damper is under vacuum conditions. In the compressed configuration, the elastic rings are deformed due to a compression force. This deformation of the elastic rings prevents metal-to-metal contact between the vacuum pump and a vacuum chamber to which the pump is connected through the damper.

Abstract: A strain reliever for a hollow tube is disclosed. The strain reliever has a fitting dimensioned to fit at a tube segment and a tapered sleeve extending from the fitting.

Abstract: Provided is a flexible hose assembly having a flexible tube for conveying fuel through a first fuel passage formed interiorly of the flexible tube and a flexible hose surrounding the flexible tube and forming therewith a second fuel passage. The flexible tube provides internal support for the flexible hose while also allowing for flow of fuel through the second fuel passage and the fuel passages are separate from one another along a length of the flexible hose assembly. When one of the fuel passages is in a low flow or no flow condition, fuel flowing through the other of the fuel passages acts to cool the fuel passage in the low flow or no flow condition to prevent stagnant fuel in the passage from heating up and coking.

Abstract: A cam and groove coupling joint has a male coupling and a female coupling that includes two pairs of lugs on the body and further includes pins supported by each pair of lugs. A pair of cam arms are pivotally mounted to the pins between the lugs. The cam arms are movable between an open position in which the male coupling is free to move relative to the female coupling and a closed position in which a cam of each cam arm engages the groove to lock the male coupling inside the female coupling. A rotatable wire clip secures the cam arms in the closed position, the wire clip being rotatably connected to each lug between a secured position in which the wire clip secures the cam arm to prevent opening of the cam arm and an unsecured position in which the cam arm is free to be opened.

Abstract: A seismic slip joint may include a fixed sealing surface, a moveable sealing surface, and a solenoid device. The moveable sealing surface is configured to engage the fixed sealing surface to form a sealing interface during a deactivated state. The sealing interface may be a juncture that precludes passage of a fluid therethrough. The solenoid device is configured to switch between the deactivated state and an activated state. The solenoid device may include a piston and a spring structure. The piston is connected to the moveable sealing surface. The spring structure exerts a force on the piston so as to press the moveable sealing surface against the fixed sealing surface to form the sealing interface during the deactivated state. The piston may be configured to compress the spring structure and retract during the activated state so as to separate the moveable sealing surface from the fixed sealing surface.
