IPC: B43K23/12
Filed: 1982-09-17
Abstract: A writing instrument having a closure cap assembly (1, 2, 3, 4 and 5) which can be placed in a sealing manner on the writing tip (20), whereby a positive engagement with an indentation in the writing tip is established via an elastically deformable finger (8), when the closure cap is in place on the writing tip. On the inner face of the arm (8), oriented toward the writing tip (20), at least one cam face (13) is located in a chord plane of the circle forming the closure cap opening. Whereupon a twisting of the entire mounted closure cap assembly (1, 2, 3, 4 and 5) brings the cam face (13) into engagement with a correspondingly formed wedge face (27) of the writing tip (20), so that the arm (8) is pivoted radially outward, and the closure cap can be removed.

Abstract: Die anaerobe Aufbereitung bzw. Reinigung furfurolhaltiger Abwässer und insbesondere des Brüdenkondensats der Sulfitablaugeneindickung bei der Zellstoffabrikation in Abwesenheit von sulfatreduzierenden und methanogenen Bakterien kann gemäß der Erfindung durch Zusatz furfurolabbauender Bakterien ohne weiteres gestartet und gesteuert werden. Solche furfurolabbauenden Bakterien wurden ausgehend von einer Quelle für anaerobe Bakterien wie Moor, Sumpf oder insbesondere Klärschlamm unter Zwischenanreicherung in kontinuierlicher Flüssigkultur unter Zufütterung furfurolhaltiger Lösung durch eine spezielle Selektionstechnik erreicht, bei der die Bakterien (in unterschiedlichen Konzentrationen) in Agar fixiert werden, der mit einer verdünnten Lösung von Furfurol überschichtet wird, das als einzige Kohlenstoffquelle dient und beim Eindiffundieren in den Agar einen Konzentrationsgradienten ausbildet, innerhalb dessen auf alle Fälle ein für die Bakterien verträglicher Konzentrationsbereich vorhanden ist. Auf diese Weise wurden diskusförmige, beigefarbene Einzelkolonien von furfurolabbauenden Bakterien erhalten, die stark beweglich sind, leicht S-förmig gebogene Stäbchen mit Geißel darstellen und morphologisch dem Desulfovibrio gigas ähnlich sind.

Title: Rotating NMR probe for measuring magnetic susceptibility
Inventor: HENTSCHEL MANFRED DR
IPC: G01R33/30
Filed: 1983-04-22
Abstract: The invention relates to a concentric, hollow-cylindrical or toroidal NMR probe which is rotated around the axis of rotational symmetry which has, in turn, a perpendicular component with respect to the external magnetic field. The probe can be used cost-advantageously in any high-resolution NMR spectrometer and is used in research and material testing for measuring diamagnetic and paramagnetic bulk susceptibility, inter alia for detecting material flaws. The rotation of the probe provides a first-order separation of the residual inhomogeneities in the external magnetic field from the NMR measurement signal. The absolute measurement precision thereby achieved of 10<-10> cgs units is comparable with, or better than, other contemporary techniques. The measuring probe is optimised for the material to be measured by suitable choice of the susceptibility of the probe wall material.

Title: Device for checking a laser range finder
Inventor: JAEGLE BRUNO DIPL ING
IPC: G01S7/497
Filed: 1983-07-14
Abstract: A test device for selective checking and fault finding in a laser range finder is proposed in which a measuring system is simulated by a first optical delay line. In front of the light entrance opening of this delay line, an inclined reflection plate with light transmission opening is arranged which reflects light into a second optical delay line in the case of a misadjustment of the laser transmitter. This reflected light is added again to the laser beam with a time delay which causes a double echo in the laser receiver. The adjustment of the laser receiver can be checked in a similar manner by means of a second reflection plate and an associated third optical delay line. Finally, a part-beam can be branched off from the laser beam emerging at the transmitter and can be supplied, after passing through a short fibre-optical line, to an opto-electronic transducer, the output signal of which is a measure of the energy density of the laser beam emerging at the transmitter.

Abstract: Satellite radio ground station antenna arrangement operating on the Cassegrain principle. In the case of a Cassegrain antenna, which is supplied by a beam waveguide and can be pivoted about an azimuth and an elevation rotation axis (11, 10), and whose supply input/output is located in a fixed-position operating space (12), the supply system consists of an excitation horn radiator (5), whose supply side projects into an operating space projection (15), in the azimuth rotation axis (11), a deflection mirror (8) in the azimuth rotation axis and two deflection mirrors (6, 7) in the elevation rotation axis (11). The three deflection mirrors (6, 7, 8) and the catchment and main reflector (3, 1) are supported by means of a holding device (17, 18) as an entity, such that they can rotate about the azimuth rotation axis. The main reflector, the catchment reflector and the deflection mirror (6), which is located behind a central main reflector opening (4) and, in radiation terms, follows the catchment reflector, are jointly articulated on the holding device in order to rotate about the elevation rotation axis. The design measures according to the invention allow satellite tracking of the antenna in relatively large spatial angle ranges. The antenna arrangement according to the invention is suitable for satellite radio ground stations having antenna reflectors with a relatively large diameter. <IMAGE>

Title: Brake pressure control valve, especially for a brake booster
IPC: B60T8/90
Filed: 1984-06-02
Abstract: The brake pressure control valve (2), which is an integral part of a vehicle brake system, is connected to a pressure supply (5) and has a housing (18), a control slide valve (19) which is displaceable by way of a pedal and a control sleeve (20). The control slide valve (19) is displaceable inside the control sleeve (20). The control sleeve (20) is designed in the nature of a stepped piston and is arranged so that it can slide inside stepped cylinders (32, 33, 34) located in the housing (18) and is shifted into a starting position by actuation in the range of one step with pressure from the pressure supply (5). A closed end (20b) of the control sleeve (20) is also acted upon by pressure from the pressure supply (5) by way of an electrically controllable control valve (41). Acting upon the end (20b) pushes the control sleeve (20) out of the starting position relative to the control slide valve (19), so that a brake pressure is introduced into the vehicle brake system. The brake pressure control valve (2) can easily be built into a vehicle and allows brake pressure to be provided as needed without operating the pedal (64), for example for testing brake circuits for leaks and for overcoming wheel slip.
