Patent number: 10082413Abstract: A potentiometric sensor, comprising: a potentiometer track; a collector track opposite the potentiometer track; a conductive magnetic cushion slider coupled to the potentiometer track and the collector track; and a sealed body housing the potentiometer track, the collector track, and the conductive magnetic cushion is disclosed. The potentiometric sensor may provide a variable output voltage indicative of a level of liquid in a container. The output voltage of the potentiometric sensor may be based on a position of a magnet, which may determine a position of the conductive magnetic cushion or a ferromagnetic spring. The magnet may be outside of the sealed body. As the sensor will be more cost effective and less space consuming, the totally sealed sensor incorporating the conductive magnetic cushion or a ferromagnetic spring may replace many applications that allow a hysteresis of less than 1 mm. Additionally, these applications may be used on rotary systems.Type: GrantFiled: August 7, 2015Date of Patent: September 25, 2018Assignee: M MICRO TECHNOLOGIES, INC.Inventor: Frank Hermann Dietrich

Patent number: 6476707Abstract: By using a two-part assembly of a rotary member (10) bearing one or more wipers (14) clipped on to a substrate member (1) bearing one or more tracks (3), subassemblies may be supplied which can be used by manufacturers of articles (20,21,22) in which it is desired to sense the angular position of one member (20) relative to another (22), but which are easy to install and reliable in use. The assembly provides substantial savings in terms of the number of individual components used, thus reducing manufacturing and assembly costs. Manufacturing costs may also be reduced by using track material as a bearing material, as both track and bearing may be applied simultaneously, e.g. by screen printing.Type: GrantFiled: December 21, 2000Date of Patent: November 5, 2002Assignee: AB Electronic LimitedInventor: Frank Hermann Dietrich

Patent number: 4742814Abstract: A process for the production of sugars, and optionally cellulose and lignin, from lignocellulosic vegetable materials which comprises subjecting the vegetable materials to a chemical pretreatment with a mixture of water and lower aliphatic alcohols and/or ketones at a temperature from 100.degree. to 190.degree. C. for a period of from 4 hours to 2 minutes with control of the breakdown of the hemicellulose components followed by separation of residue and a subsequent main chemical treatment with a similar solvent mixture at elevated temperatures for a further period of from 6 hours to 2 minutes.Type: GrantFiled: January 30, 1987Date of Patent: May 10, 1988Assignee: Bau- und Forschungsgesellschaft Thermoform AGInventors: Michael Sinner, Hans-Hermann Dietrichs, Jurgen Puls, Werner Schweers, Karl-Heinz Brachthauser

Patent number: 4587285Abstract: Aqueous heat-curable compositions which are based on known heat-curable condensation products of aldehydes and OH- and/or NH.sub.2 -containing compounds, which contain hemicellulose-cleavage products having an average degree of polymerization, DP, of 5 to 100 and of at least 10% by weight, relative to the total weight of heat-curable materials, and aldehydes, in an amount of 5 to 50% by weight, relative to the weight of hemicellulose-cleavage products. The invention also relates to the use of these compositions for glueing and for preparing moldings.Type: GrantFiled: April 7, 1983Date of Patent: May 6, 1986Assignee: Fritz-Werner Industrie-Ausruestungen GmbHInventors: Cihan Ayla, Hans-Hermann Dietrichs, deceased, Jurgen Puls, Michael Sinner

Patent number: 4553295Abstract: A mechanism for the lathe-working of longitudinal, cylindrical, or slightly conical work-pieces (88), preferably cartridge cases for firearms, which uses at least two driven rotating spindles (80) located in a housing (17). The housing (17) is rotatable around an axle (16) and is rotated by a hydraulic or pneumatic cylinder (22, 23) into a series of operating positions. Tools for working the cartridge cases (88), (a) a shaper for the extractor groove (93) and the extractor flange (92) and (b) a cut-off piece (103), are both attached to a cut-off sled (101). This cut-off sled (101) is guided back and forth on a main sled (94) laterally with respect to the axis of rotation of a spindle (80). The main sled itself may be moved in the direction of the axis of rotation of the spindle (80). In this manner, the length of the cartridge case is determined exactly. Furthermore, each rotating spindle (80) is driven individually.Type: GrantFiled: April 20, 1984Date of Patent: November 19, 1985Assignee: Ingenieurburo, Hermann DietrichInventor: Hermann Dietrich

Patent number: 4483209Abstract: A spindle drive for measuring devices comprises a threaded spindle with a nut threadably engaged on the spindle and with one of them being rotatable to cause displacement relative to the other along a longitudinal direction in relation to the spindle. A nut carries a slide portion with vertically extending posed blind bores carrying bushings with ball races therein. A measuring carriage is affixed and forms part of a support portion which extends over the slide and the measuring carriage portion extend below the slide. A drive pin is carried by the support portion and the measuring portion and it is confined for movement within the respective bushings. A screw bolt is connected between the support portion and the slide and it may be threadably adjusted to permit vertical adjustable positioning of the slide relative to the measuring carriage and the support portion.Type: GrantFiled: November 3, 1982Date of Patent: November 20, 1984Assignee: Mauser-Werke Oberndorf GmbHInventors: Hermann Dietrich, Hans J.
