A door hold-open device including a track, a first catch slidably mounted for longitudinal movement in the track, a stop assembly including a second catch coupled to the track and adapted to engage the first catch wherein the second catch is moveable in a direction different than the longitudinal direction, a resilient member that applies a force to the second catch to urge the second catch into a position where the second catch engages the first catch when the first catch is adjacent to the sec...

On the basis of any conventional suitable container (1), this system incorporates a set of elements which act in a distributed manner (2), which using the information supplied by a series of temperature sensors (4) and activated by a data acquisition and control system (3) make it possible to pump heat out of the container or into the same, these elements preferentially taking the form of Peltier cells, and a series of distributed sensors (6), consisting of a humidity sensor (7), a vibration sen...

A double-sheet stent for insertion into a lumen of a vessel of living being, comprises constructive elements, preliminary formed in a shape of the two mainly similar stencils I and II on the surface of the two thin sheet metallic blanks. The stencils I and II are preliminary superimposed one on another in order to be shifted for a winding outline width along the stent longitudinal axis and to form the alternating winding outlines pairs. One pair of the winding outlines is executed by a simple su...

The nozzle for a pressurized container is mounted to the container for shipment and sale by a hook member. The hook member has a hook portion that mounts to the valve cup rim or container rim. An attachment leg connects the hook portion to the nozzle. The hook portion has a slip-fit relationship to the rim on which it is placed. The wall of the hook portion that rests along the outside of the rim is thinner than is the wall that rests along the inside of the rim. This arrangement accommodates th...

The likelihood of chlamydia infection can be prevented by the topical application of metallo-organic cobalt compounds according to the following formula to the cite of infection: ##STR1## wherein each A may be the same or different and is an alkyl group, a phenyl group or a substituted derivative of a phenyl group; each Y may be the same or different and is hydrogen, an unbranched alkyl group, a halide or a group having the structure wherein R is hydrogen, an alkoxide group, and alkyl group, or ...

A first step models a hot zone in a pulling apparatus of a single crystal as a mesh structure, and a second step inputs physical property values of each member corresponding to meshes combined for each member of the hot zone into a computer. A third step obtains the surface temperature distribution of each member on the basis of the calorific power of a heater and the emissivity of each member, and a fourth step obtains the internal temperature distribution of each member on the basis of the sur...

The internal combustion engine comprises at least one combustion chamber for burning a fuel in timed explosions accompanied by formation of a combustion gas, at least one expansion chamber which is connected with the combustion chamber and separate from the combustion chamber and which has a piston for converting energy of the combustion gas into mechanical energy or work, and a cam gear unit by which a drive shaft can be driven by the piston and which has a cam disk and associated thrust member...

A suspension of a valve plate of a vacuum valve at a valve rod has a bearing block of rubber-elastic material with first and second side surfaces, one of which side surfaces is fastened to the valve rod or to a plate which is rigidly connected with the latter, and the other side surface is fastened to the valve plate or to a plate which is rigidly, connected with the latter, wherein an inelastic force transmission part is embedded in the rubber-elastic material of the bearing block and extends a...

The present invention concerns a flexible stapling device (1). More particularly, this invention concerns a flexible endovascular stapling device (1) for an intravascular procedure such as patent foramen ovale closure, which is designed to avoid open heart surgery by permitting the closure of the defect utilizing a stapling means (26) which is positioned by using a flexible shaft/guidewire system.

A butterfly valve comprises a valve housing with a valve opening and a valve seat, this valve housing enclosing a vacuum area of the valve; a valve plate which is mounted at a valve rod guided through the valve housing and which is pressed against the valve seat in a closed position of the valve, tilted relative to the valve seat in a partially open position of the valve through tilting of the valve rod about a tilting axis, and tilted and rotated relative to the valve in a completely open posit...
