Patent DE-4301012-A1 (DE)
Title: Control circuit for hydraulic steering for vehicle
Inventor: BERGMANN ERHARD DR
IPC: B62D5/09
Filed: 1993-01-16
Abstract: The hydraulic system for the vehicle has a single hydraulic pump to supply several hydraulic circuits including the hydraulic steering. The steering has priority and is fitted with a non-return valve (12) to isolate the steering circuit from the remainder of the hydraulics as well as a pressure reservoir (13) to cover pressure fluctuations.The pressure reservoir is positioned downstream of the non return valve and is filled from the supply. If the steering is returned to neutral and is immediately reset then the temporary drop in system pressure is compensated by the pressure reservoir.

Title: Method and device for calibrating strongly fluctuating measuring signals for the quantitative analysis of gas mixtures by means of resonant laser mass spectrometry
Inventor: WEICKHARDT CHRISTIAN DIPL PHYS
IPC: H01J49/16
Filed: 1993-02-26
Abstract: The quantitative determination of the concentrations of the individual substances of a complex gas mixture by means of resonant laser mass spectrometry is complicated owing to the fact that the measuring signal fluctuates strongly from shot to shot because of the fluctuation in the intensity of the laser beam. A simple standardisation by division by the intensity of the laser beam is not a general solution, because in the general case of laser ionisation, i.e. multiphoton ionisation, the signal intensity is not linear, but depends on the intensity of the laser beam as a function of a relatively high power, which changes from substance to substance. The invention relates to a method with which it is possible with the aid of two calibration substances to eliminate the critical signal fluctuations, and thus to obtain quantitative information. <IMAGE>

Abstract: A hitch carrier for a vehicle trailer hitch, the free end of which hitch carrier can be plugged into a guide sleeve 1 which is arranged on the vehicle. The free end is coupled here to a cylindrical engagement bolt 3 which is seated transversely in the plug-in opening of the guide sleeve 1. At the free end 2, an insertion slot 2a, which is open to the end side, is arranged to receive the engagement bolt 3 and a curved element 4 is rotatably mounted behind the latter, the said curved element 4 having a partially cylindrical open circumferential recess 4a''' for the engagement bolt 3 and curve stops for a' which are acted on by guide stops 5a', 5a'' of a pushing element, 5b. This pushing element 5b is longitudinally guided in the free end 2 and in an initial basic position is acted on by the guide stops 5a' in such a way that it is held tight with tensioning of a spring 6 supported in the free end 2. When the free end 2 is inserted into the guide sleeve 1, as a result of the curved element 4 striking the engagement bolt 3 the said pushing element is made to rotate and is released from the initial basic position, longitudinally pushed in a tangential fashion in the direction of the curved element 4 under the pressure of the spring 6 and it is made to continue to rotate as far as a locked position. In this locked position a curved stop section 4a''' of the curved element 4 acts on the engagement bolt 3 while embracing it. With renewed longitudinal displacement of the pushing element 5b counter to the effect of the spring 6 a reversal of the direction of rotation of the ... Original abstract incomplete. <IMAGE>

Title: Open=end spinning rotor shaft mounting - has radial support between support discs and free end of shaft
Inventor: BREITENHUBER JOSEF
IPC: D01H4/12
Filed: 1993-07-28
Abstract: In the guide system for the shaft (11) of a rotor, in an open-end spinner, a support (9) to restrict the radial movement of the rotor shaft (11) is between the free end (111) of the shaft (11) and the stress zone (A) at the pair of support discs (4) nearest to it. The free end (111) of the rotor shaft (11) projects over the support discs (4) by a length of up to 10 mm. The radial support (9) is at least partially at the last 5 mm of the rotor shaft (11). Also claimed is a radial support (9) which is at least partially dish-shaped so that it can engage at least partially the axial bearing with the rotor shaft. Pref. during normal working, the support (9) is not in contact with the rotor shaft (11). The support (9) holds the rotor shaft (11) over a length of at least 2 mm, and is located at least partially in the stress zone (A) at the support discs (4), in a dish shape round part of the rotor shaft (11) circumference. The support (9) is integrated with the aerostatic axial bearing (6) into a component unit, or it is inserted into a holder in the base body of the axial bearing (6). The support (9) can be at least partially bush shaped. USE/ADVANTAGE - The guide and mounting system supports the rotor shaft in an open-end spinner, rotating at speeds around 120000 rpm. The system gives radial support, without altering the geometric structure, at the free end of the rotor shaft.

Title: Continuously adjustable locking device for extendible hangers on Christmas-tree balls
Inventor: STROBEL FRIEDRICH
IPC: A47G33/10
Filed: 1993-08-26
Abstract: To achieve a continuously adjustable locking device for extendible hangers on Christmas-tree balls or hollow bodies serving similar purposes, a continuously adjustable locking device of elastic material which encompasses the shaft of the extendible hanger and is arranged directly under the cap, mounted in a known manner, on the blowing opening is advantageous. The friction between the continuously adjustable locking device and the shaft of the extendible hanger ensures that, on the one hand, the inserted extendible hanger is reliably protected against unintentionally sliding out and, on the other hand, the extension length can be fixed at any point in continuously adjustable fashion over the entire length of the shaft. Recesses made at the edge of the continuously adjustable locking device make possible the equalisation of air pressure between the inner space and surroundings. If the continuously adjustable locking device is made thin in its edge region and the central part downwardly curved, an advantageous overall height can be obtained without reduction of the necessary friction. Punctures or incisions made initially in the continuously adjustable locking device facilitate assembly.
