Publication number: 20030051926Abstract: An electronic balance including a housing (1), a weighing scale (2), a windshield (3), which preferably at least partially surrounds the weighing scale, and a display and operating unit (4) which is connected to the balance housing. The connecting part (5) between the display and operating unit (4) and the housing (1) consists essentially of a material with poor heat conduction properties. At least one vertical radiation protection plate (6) is provided between the display and operating unit (4) and the housing (1), and the connecting part (5) is configured in such a way as to impair air convection on both sides of the radiation protection plate(s) (6) preferably to the least extent possible.

Patent number: 6515238Abstract: An analytical balance that includes a balance scale, a wind guard encircling the balance scale, and an apparatus for generating an ionized stream of air for dissipating electrostatic charges of goods to be weighed. The apparatus for generating an ionized stream of air includes a blower that draws in air from the weighing space into at least one boundary surface of the weighing space. The blower also recycles the air back into the weighing space via at least one exhaust opening at another point. In this manner, highly effective dissipation of electrostatic charges is possible, and the stream of air can be conducted so that it exerts scarcely any vertical forces on the goods to be weighed. The analytical balance is very user-friendly in operation. Additionally, the apparatus for generating an ionized stream of air is preferably structured to be an easily installed optional component of the analytical balance.Type: GrantFiled: November 8, 2000Date of Patent: February 4, 2003Assignee: Sartorius AktiengesellschaftInventors: Joerg-Peter Martens, Heinrich Feldotte, Steffen Hirche, Eduard Bierich, Guenter Boetcher

Publication number: 20020057456Abstract: A method and a diagnostic device for a printing press are described, wherein data is automatically transmitted by a central data processor of the printing press to a locally distanced central data processor when a threshold value is upwardly transgressed, downwardly transgressed or reached. The data is preferably assessed prior to the evaluation and/or the transmission to the remote central data processor. In this way, a simple telediagnostic service of the printing press is possible.Type: ApplicationFiled: November 15, 2001Publication date: May 16, 2002Inventors: Lucia Dauer, Andreas Detmers, Jurgen Fitzer, Marcel Kiessling, Klaus Kremer, Peter Marten, Gotthard Schmid

Publication number: 20010052431Abstract: An electronic weighing sensor (10) having a digital signal processing unit (19), which includes at least one filter (12) with low-pass characteristic. By means of the filter (12), the direct-current component (m) is determined from the output signal of the weighing sensor and the weighing result is derived therefrom. A signal, which is dependent on the amplitude of the vibrations, is determined by the digital signal processing unit (19) and electronic components (18) change the direct-current component (m) as a function of the magnitude of the vibration-dependent signal. This significantly improves the performance of the weighing sensor (10) with respect to shocks and vibrations in the installation site of the weighing sensor (10).Type: ApplicationFiled: May 21, 2001Publication date: December 20, 2001Applicant: SARTORIUS AGInventors: Alfred Klauer, Joerg Peter Martens

Patent number: 6103885Abstract: The Invention pertains to a process for the amidation of a material having at least one carboxyl-containing polysaccharide. The provided process involves a first step in which the carboxyl groups are reacted with an ammonium donor of the general formula >NH to form the corresponding polysaccharide carboxyl ammonium salt, and a second step in which the polysaccharide carboxyl ammonium salt is heated so as to convert the ammonium groups into the corresponding amido groups. The invention also pertains to fatty amide modified carboxyl-containing polysaccharides, and particularly to fatty amide modified carboxymethyl cellulose. The products in accordance with the invention can be widely employed, e.g. in the field of biodegradable plastics, as anti-redeposition agents for synthetic fibers, as polymeric emulsifiers, as pigment dispersing agents, in cosmetic applications, as thickeners, as oil drilling fluids, as superabsorbers, and in mineral processing.Type: GrantFiled: November 14, 1995Date of Patent: August 15, 2000Assignee: Akzo Nobel NVInventors: Jan Gerardus Batelaan, Peter Marten Van Der Horst

Patent number: 5878495Abstract: A method of manufacturing a dynamic groove bearing having parts rotatable relative to one another. The bearing parts include cooperating bearing surfaces and a pattern of grooves by means of a metal-removing tool. A first bearing part is fastened to a rotatable support of a machine tool, which is rotated in a constant direction. The tool is periodically displaced relative to the first bearing part parallel to a direction transverse to the bearing surface of the first bearing part by a positioning device with a frequency which is determined by a product of a rotation frequency of the support and a number of grooves on the bearing surface of the first bearing part. The tool is periodically displaced in a sinusoidal movement and the positioning device may include a piezoelectric actuator (95). A data storage unit including dynamic groove bearings is also provided.Type: GrantFiled: April 4, 1996Date of Patent: March 9, 1999Assignee: U.S. Philips CorporationInventors: Peter Martens, Johannes C.
