An electrical connector assembly comprising a receptacle connector and a pin header is disclosed. The receptacle connector is attached to wires and the pin header can be secured to a printed circuit board. The receptacle connector is secured in the shrouded pin header by a double acting connector latch extending upwardly from one wall of the header housing. Connector latch comprises a yoke section with upwardly extending deflectable arms and a centrally disposed downwardly extending deflectable ...

Log singulating apparatus comprises two sets of interleaved support surfaces which reciprocate in the feed direction. Successive support surfaces are vertically overlapped and laterally offset and the two sets of support surfaces reciprocate out of phase by 180 degrees in relation to one another. Logs are promoted in the feed direction by abutment surfaces associated with each support surface. At the extremes of stroke of the sets of support surfaces, the abutment surfaces of overlapping support...

Pharmaceutically-active materials comprising specific antidepressant compounds, such as sertraline, contained in microparticles formulated so as to release the antidepressant compounds over an extended period of time are disclosed. The materials, when administered, particularly by injection, release the active agent over time allowing the patient to be effectively treated without requiring multiple dosing of the pharmaceutical material. Pharmaceutical compositions containing the microparticles a...

The subject invention concerns novel compounds that are useful as ultrashort acting hypnotic barbiturates. Specifically exemplified are derivatives of barbituric and thiobarbituric acids. They are rapidly metabolized by blood and tissue enzymes to form polar metabolites with no hypnotic activity and which are rapidly eliminated.

The invention relates to an endoscope comprising a first quick-acting closure (3) for a traction wire (13) of a Bowden wire device, which closure is arranged at the proximal end to be pivotable or displaceable, with a locking position of the quick-acting closure (3), in which an attachment unit for loosening and attaching the traction wire (13) of the Bowden wire device can be actuated and with a working position of the quick-acting closure (3), in which the attached traction wire of the Bowden ...

A pressure regulator having a housing with an inlet port and an outlet port. A plug is located within the housing and dividing the housing into an upper chamber and a lower chamber, with the upper and lower chamber being connected by a vent. The plug includes a fluid path between the inlet port and the bore. A yoke is adapted selectively close the fluid path in the plug. A diaphragm is located in the upper chamber and is connected to the yoke. A biasing member biases the yoke to open the fluid p...

An upwardly acting sectional door (24), including a plurality of panels (40), body portions (50) of the panels constructed of a flexible polymeric material and having a front surface (55), a cladding (80) covering the front surface of the body portions and having hooks (83, 84) at the upper and lower edges thereof, a hinge member (51) at an edge of the body portion operatively engaging the hooks of adjacent of the panels to provide relative pivotal motion between adjacent panels. Another embodim...

A plunger device for unblocking a clogged drain or pipe, comprises a valve housing interposed between a handle and a suction cup; a valve seat having an opening for communicating the cup with the housing; a fluid outlet formed in the housing to provide a fluid path to the outside of the device; a valve ball positioned in the housing to close said opening of the valve seat and said fluid outlet when said ball is positioned on the seat, a bolt moveable in said housing to abut said ball for locking...

A fast acting polarity detector uses a "very fast" polarity detector in tandem with a "precise" polarity detector to increase the maximum speed achievable from an A/D converter that employs a 1-bit folding front end. The fast polarity detector is a coarse polarity detector that immediately controls the 1-bit folder. The precise polarity detector operates more slowly, but more accurately. When the output of the precise polarity detector becomes available, it overrides the output of the fast polar...

A pair of end plates are maintained in a spaced apart relationship by a plurality of guide rods secured therebetween. A carriage defines a plurality of apertures which receive the guide rods and which provide slidable support for the carriage between the end plates. An elongated externally threaded pump screw is rotatably supported between the end plates and is coupled to a bi-directional motor. A ball nut is secured to the movable carriage which engages the pump screw such that rotation of the ...
