Patent DE-3811625-A1 (DE)
Title: Pump for pressures exceeding a thousand bar
Inventor: EICKMANN KARL
IPC: F04B43/067
Filed: 1988-04-07
Abstract: In pumps for non-lubricating fluid with delivery pressures exceeding a thousand bar, there is the problem that the service life is limited by the number of strokes of the separating parts and valves. Such pumps therefore have a low speed in order to achieve a sufficient hourly operating figure. Since the primary drive units, such as diesel engines or electric motors, run at high speeds, expensive and voluminous reduction gears were necessary, the service life of which was likewise limited and which, despite their high costs, caused noise and operational unreliability. The invention overcomes these difficulties in that it allows a distributor to rotate at low speed, which distributor then conveys pressure fluid to the high-pressure pistons - mostly with a medium-pressure piston intermediate stage - so as to allow the valves and separating means, such as the diaphragms, V-elements and the like, to work with a small number of strokes per unit time. In the case of other embodiments, the distributor is replaced by sequence signals which initiate the next piston immediately after the end of the pressure stroke of the previously forcing piston. Furthermore, details which promote the simplicity or the service life are described. A particularly practical exemplary embodiment uses a hydraulic motor of large absorption volume to drive the control shaft and thus forms the reduction ratio of a commercially available transmitting pump for the unit of the invention.

Title: Magnetic material and method for producing it
Inventor: WECKER JOACHIM DR
IPC: H01F1/057
Filed: 1988-07-26
Abstract: The at least three-component magnetic material has at least one element (R or M, respectively) each from the group of the rare earths and from the iron group. According to the invention, the material should contain, at least in part, a phase of an intermetallic compound which at least approximately has the composition R6M11Ga3 (R = rare earth including La; M = Fe, Co, Ni). This material can be produced, in particular, by a prealloy first being produced from the components (R, N, Ga) in the desired concentration ratio, followed by there being formed, from the melt of said prealloy and using a rapid-solidification technique, a finely crystalline or amorphous product containing the R6M11Ga3 phase. <IMAGE>

Title: Method and device for detecting an error in a signal corresponding to the speed of a vehicle
Inventor: HELMSTAEDTER GERALD
IPC: G05D13/04
Filed: 1988-09-24
Abstract: The subject-matter of the invention is a method and a device for detecting an error in a signal corresponding to the speed of a vehicle. This signal is compared with at least one limiting value corresponding to a speed limiting value. In the event of agreement between the signal and the limiting value, or in the event of a signal which is situated outside the permissible range determined by the limiting value, a signal corresponding to the rotational speed of a vehicle is checked for overshooting of a prescribable rotational speed value during a prescribable time interval. An error reaction is produced in the event of overshooting of the rotational speed limiting value during the time interval.

Title: Device for blocking door handles
Inventor: HARMS GERALD DIPL ING
IPC: E05B39/02
Filed: 1988-12-07
Abstract: The device for blocking door handles comprises a housing which is arranged in the movement region of the door handle and can pivot out of a position which blocks the door handle into a position which releases the door handle, and can be arrested there. In order that a certain inhibiting threshold, preventing misuse, is set against the actuation of such a device, a safety glass 6 is arranged in the housing 2, 3, the direct destruction of which safety glass permits the housing to pivot into the position which releases the door handle, or else the safety glass is destroyed by direct pivoting of the housing into the position which releases the door handle. There are thus two possible actuations of the device in order to release the door handle. In the case of one, the safety glass is subjected to pressure and is destroyed directly thereby, and, in the case of the other, the housing is pivoted, the safety glass, however, likewise being destroyed in an indirect manner. In both cases, the destruction of the safety glass, which virtually forms the locking element for the housing 2, 3, indicates actuation of the device. <IMAGE>

Patent DE-3936890-A1 (DE)
Inventor: SANGUINETTI-RAFFO CARLOS
IPC: C09D4/00
Filed: 1989-11-06
Abstract: Permanently adhesive and reversibly usable adhesive compositions are produced on substrate materials by monomer mixtures which on polymerization yield permanently adhesive, film-forming acrylic ester polymerizates. In a first process step the monomer mixtures are polymerized up to the onset of gelation, and in a second process step the gelled reaction mixture is size-reduced mechanically and applied to the substrate material. A coherent film layer is then formed on the substrate by heat treatment. If necessary, in the second process step the reaction mixture is diluted with solvent and subjected to a shearing stress in order to spread the gel. The subsequent heat treatment should be carried out at temperatures of 90 to 170  DEG C.
