Title: Affinity sensor for concn. measurements of low molecular wt. analytes - consists of a hollow fibre or microcapsule contg. 2 macromolecular affinity ligands one of which can be displaced by the analyte
Inventor: EHWALD RUDOLF PROF DR
IPC: G01N33/543
Filed: 1992-02-04
Abstract: An affinity sensor for measuring the concn. of a low molecular analyte consists of a hollow fibre or microcapsule with an enclosed colloidal soln. of 2 macromolecular affinity ligands. The affinity ligands do not precipitate on account of an excess of one component and on account of one or both components being monovalent. One of the affinity ligands can be displaced from its compound with the other by a lower molecular analyte. The membrane of the hollow fibre or microcapsule is permeable for the analyte and impermeable for the two high molecular affinity ligands. The viscosity of the soln. within the hollow fibre can be registered with a physical measuring device. USE/ADVANTAGE - The sensor can be used for many possible cases of affinity-bonding relationships and does not require immobilisation of an affinity ligand on a surface. The sensor can be used to measure the concn. of low molecular analytes, such as sugars.

Title: Electron beam generating system
Inventor: MARGGRAF MANFRED
IPC: H01J29/48
Filed: 1993-04-26
Abstract: According to the prior art, so-called high-current cathodes are known with beam current ratings (outputs, powers) of up to 10 A/cm<2>. In addition, cathode arrangements are known in devices in entertainment electronics, whose beam current ratings are considerably below the ones described above. Since considerably improved sharpness performance can be obtained by means of increased beam current ratings, there was the demand to use high-current cathodes also for entertainment electronics. This fell through because as a result of the high temperatures of such cathodes and the required short distances between the electrode grid (12) and the cathode, and because of the extremely shallow depth of this grid (12), the high-current cathodes could not be designed in a thermally stable fashion. It was a surprise that this problem could be solved by designing the electron passage region in the grid (12) closest to the cathode to have the shape of a hat, to be specific with such a shape that the passage region comprises at least one region (23) with the electron passage opening (22), the envelope surface (24) and the edge piece (26), the envelope surface (24) assuming an angle  alpha  of between larger than 95 DEG and smaller than 175 DEG  relative to the region (23). <IMAGE>

Abstract: A safety belt arrangement for motor vehicles has a winding roll (11) which is acted upon by a winding spring (12), a locking device (16) and a tensioning device (17). The tensioning device (17) is composed of a tensioning disc (18) having a central aperture (19) which has an internal ring gear (20) and surrounds, at a distance, a gearwheel (21) which is connected to the winding roll (11) so as to rotate with the latter. The fact that the tensioning disc (18) is releasably connected to the casing (23) makes it possible, when a pyrotechnical drive (14) is initiated by a sensor (48), for a load cable (22), which extends from the drive (24) to the tensioning disc (18), initially to release the tensioning disc (18) from the casing (28) and then to bring the internal ring gear (20) into engagement with the gearwheel (21) and in so doing to transmit to the winding roll (11) a rotary movement which is necessary for the tensioning of the safety belt (14). Means (25, 28, 29) secure the engagement of the internal ring gear (20) and the gearwheel (21). <IMAGE>

Title: Control device for a hydraulic consumer
Inventor: DWORAK WILHELM
IPC: B66F3/24
Filed: 1993-07-17
Abstract: A control device for a working cylinder (13) is proposed which controls the pressure-medium flow from a feed connection (24) to a consumer connection (18) or a return connection (26) for the pressure medium by means of a 3/2-way valve (12). The 3/2-way valve (12) has two valve members (30, 47) to which actuating elements (42, 49), different in each case and designed as springs, are allocated. Consequently, an optimum annular gap always appears between the two valve members (30, 47) during the lowering operation of the control device, so that pressure medium retained in a line (21) between the 3/2-way valve (12) and the feed connection (24) is discharged quickly and reliably. <IMAGE>
