Abstract: A connection device for valves, with a connection body extending along a main axis, which main body has several consecutive valve mounting stands in direction of the main axis, on which valve body valves can be or are mounted. The valve body is provided with at least one row of several consecutive receiving recesses likewise in direction of the main axis, which receiving recesses are transverse to the main axis and leading to a common connection surface of the connection body, which receiving recesses communicate with the connection body channels passing into the connection body and into which suitable connection units can be or are inserted for connecting fluid lines. The inserted use position can be detachably fixed to the connection body by locking means having at least one U-shaped locking bracket. The locking means contain at least two locking channels extending along the main axis in the connection body.

Abstract: A loudspeaker assembly with an integrated woofer frame and baffle component wherein the woofer frame is created as an integral part of the baffle by molding the woofer frame and baffle as a unitary component.

Abstract: A loudspeaker assembly. This invention provides for a loud speaker assembly that rear-mounts a transducer so that the sound emanating from the transducer does not pass through a “tunnel” created by the thickness of the outer baffle surface or grille frame. In addition, the loudspeaker assembly can be provided with a natural appearing cabinet and can be used outdoors.

Abstract: An interchangeable loudspeaker assembly capable of pivoting the low-frequency and high-frequency transducers to provide directional sound while avoiding hindrance of sound waves by the loudspeaker frame.

Abstract: A loudspeaker assembly with a transducer capable of being swiveled to direct the sound to a convenient point thereby allowing the listener to select the optimal direction of sound. The assembly comprises a unique design which prevents the transducer from dropping below the plane of the speaker's baffle, thereby eliminating diffraction of sound waves which arise when sound radiates off the sharp edge of the cavity wall upon rotation of the transducer. The assembly allows a listener to adjust a transducer, such as the high-range frequency tweeter component of an in-wall speaker to his liking, without the need to remove and/or re-install the speaker in the wall. The assembly is equally adaptable to the interior of a vehicle or for use as a free-standing floor speaker. The assembly provides a unique speaker with a pivoting transducer which provides quality, multi-directional sound, free from any distortion created by the diffraction of sound waves.

Abstract: A speaker assembly with a unique sound driver sub-baffle assembly which can be pivoted forward and backward, as well as rotated clockwise or counter-clockwise 360 degrees via the use of a rotatable turntable mounted within the speaker's baffle. The assembly allows a listener to manually alter the orientation and direction of the speaker's transducers thereby allowing for optimal dispersion control after the speaker is installed in a wall, regardless of the speaker's position within a room. The sub-baffle assembly, when pivoted to its maximum limit, provides a flush, continuous surface with the inner rim of the rotatable turntable, allowing a listener to control dispersion of the sound waves without creating distortion. Further, the transducers embedded within the sub-baffle assembly are maintained in a coplanar relationship throughout rotation and pivoting.

Abstract: A method and a layered planar heterostructure comprising one of or both n and p-channel field effect transistors is described incorporating a plurality of semiconductor layers on a semiconductor substrate wherein one layer is silicon or silicon germanium under tensile strain and one layer is silicon germanium under compressive strain whereby n channel field effect transistors may be formed with a silicon or silicon germanium layer under tension and p-channel field effect transistors may be formed with a silicon germanium layer under compression. The plurality of layers may be common to both subsequently formed p and n-channel field effect transistors which may be interconnected to form CMOS circuits. The invention overcomes the problem of forming separate and different layered structures for p and n-channel field effect transistors for CMOS circuitry on ULSI chips.

Abstract: The ability to measure the ratio of vapor versus liquid in a nuclear steam generating system is highly desirable, particularly since, during transient events such as rapid depressurization, the vapor may not be in thermal equilibrium with its liquid and its distribution in the liquid may be highly non-uniform. By using a relatively mono-energetic neutron source such as Californium 252, exposing the medium under investigation to the radiation and using a proton recoil detector as an energy discriminating counter one can estimate the ratio of vapor to liquid by measuring the reduction of flux loss due to scattering when the medium includes vapor as well as liquid.
