IPC: B01D33/04
Filed: 1993-10-21
Abstract: The invention relates to a vortex body for devices for separating off water from suspensions, in particular from sludges. Use is possible not only on filter belt presses but also on belt thickeners or comparable devices. The invention has the purpose of clearing parts of the filter surface, loosening, circulating and vortexing the filter material and accelerating the separation of the free water from the filter material.

Patent DE-4341177-A1 (DE)
Inventor: VOOK DIETRICH W
IPC: H01L29/10
Filed: 1993-12-02
Abstract: In a bipolar device, selective epitaxial silicon provides an improved intrinsic-extrinsic base line 34. A trench (29, Fig. 2 not shown) physically separates an intrinsic base portion 20 and extrinsic base portion 21. The trench includes sidewalls having a thin oxide layer formed thereon. The bottom of the trench is exposed during processing. A shallow link 34 between the intrinsic-extrinsic regions of a bipolar transistor base is formed by depositing a heavily boron doped layer of silicon on the exposed portion of the trench. During subsequent processing, including rapid thermal anneal, there is some boron out-diffusion which forms a shallow diffused intrinsic-extrinsic base link. <IMAGE>

Abstract: The invention relates to a testing device for determining any eccentric spring force introduction into the spring plate of a helical compression spring (1) supported in operation at least with one of its two ends on a spring plate, in particular a helical coil spring of a vehicle suspension system. The testing device essentially contains two coaxial spring receivers (2, 3), spaced apart from each other, for the axial support of both spring ends of the helical compression spring (1) to be tested, and a tensioning device (4), by means of which an axial force (F) can be exerted on the helical compression spring (1) to be tested. One of the two spring receivers (e.g. 2) is designed as a rocker which is supported over an articulation point (5) in the framework (10) of the testing device. Provision is further made of a device cooperating with the rocker, in order to display any tipping movements of the rocker (2) occurring in the event of an introduction of an axial force (F) as a measure of the "eccentricity" of the spring force introduction into the spring receiver (2), or to display the fact that any tipping movements of the rocker (2) occurring in the case of the introduction of a defined axial force (F) exceed a predetermined maximum value. <IMAGE>
