Patent number: 9448192Abstract: A monitoring cell, used to perform a measurement in an NMR spectrometer of a reaction fluid produced by a reaction vessel, has a body having inlet and outlet transport coaxial capillaries for transporting the reaction fluid between the body and the reaction vessel. Cooling lines are also positioned coaxially with the transport capillaries to transport cooling liquid between the body and the reaction vessel. The cell further has a hollow sample probe for insertion into the NMR spectrometer and a coupler section that removably connects the sample probe to the body so that the inlet transport capillary extends through the body into the interior of the sample probe and the outlet transport capillary is sealed to the sample probe to allow reaction fluid that enters the sample probe via the inlet transport capillary to exit the sample probe via the outlet transport capillary.Type: GrantFiled: March 31, 2014Date of Patent: September 20, 2016Assignee: Bruker Biospin CorporationInventors: Brian Marquez, Michael Fey, Kimberly L. Colson, Robert Krull, Eckhard Bez, Don Piroli, Werner E. Maas

Patent number: 8212565Abstract: Each NMR rotor bearing in an NMR magic angle spinning assembly is constructed of a porous ceramic material and has no inlet channels or nozzles. Instead, pressurized gas is forced through pores in the bearing ceramic material from an annular groove at the bearing periphery to the central aperture. Since the pores are small and very numerous, the gas pressure is effectively balanced around the periphery of the central aperture. In addition, if contaminants block one or more pores during operation, the pores are so numerous that the balanced pressure can still be maintained in the central aperture, thereby preventing an imbalance that could destroy the rotor.Type: GrantFiled: October 29, 2009Date of Patent: July 3, 2012Assignee: Bruker Biospin CorporationInventor: Eckhard Bez

Patent number: 8098069Abstract: A closed container having a single opening is sealed by a plug fabricated from a self-sealing elastomer. Before insertion, the plug is transfixed with a tube to allow air to escape as the plug is pushed into the container. The plug and tube are then inserted into a container. After the plug has been seated in the container, the tube is withdrawn, allowing the self-sealing elastomeric material to close the canal formed by the tube and to form a hermetic seal.Type: GrantFiled: April 17, 2009Date of Patent: January 17, 2012Assignee: Bruker Biospin CorporationInventors: Eckhard Bez, Melanie Rosay

Publication number: 20110079288Abstract: Apparatus for preventing energy leakage from a transmission line treats the line as a “partially closed” vessel. A gas stream with a pressure slightly different from ambient pressure is provided to the interior of the transmission line and a conduit that allows gas to pass between the transmission line and the ambient environment is provided. The gas flow rate at the conduit is then detected and monitored. If the flow rate falls outside a predetermined threshold, an electrical energy leakage is indicated. In another embodiment, the pressure of the input gas to the transmission line is continuously checked by a pressure switch, which will detect a change in pressure if the transmission integrity is compromised and disable the energy source.Type: ApplicationFiled: October 1, 2009Publication date: April 7, 2011Applicant: BRUKER BIOSPIN CORPORATIONInventors: Eckhard Bez, Melanie Rosay, Leo Tometich

Patent number: 7403007Abstract: In a nuclear magnetic resonance probe, the sample coil is connected to the RF excitation source via transmission lines that are arranged to generate one or more nodal points at the 1H excitation frequency along their lengths and a balanced magnetic filed profile within the sample coil. Heat exchangers are then connected directly to the inner conductor of the transmission line at these nodal points. The transmission line inner conductors are in direct contact with the sample coil and efficiently cool the coil to cryogenic temperatures without interfering with the 1H resonance or RF profile.Type: GrantFiled: February 1, 2007Date of Patent: July 22, 2008Assignee: Broker Bio Spin CorporationInventors: Yit Aun Lim, Eckhard Bez, Xiaozhong Zhang, Werner E.

Patent number: 5632605Abstract: A multistage vacuum pump is achieved by utilizing a single piston and cylinder assembly having opposite end portions with substantially equal diameters and an enlarged diameter central portion. One end of the cylinder is closed by a valve and a first stage pumping chamber is defined between the valve and the piston. The enlarged diameter portion of the piston has an axial extent less than the axial extent of the enlarged diameter portion of the cylinder to define second and third stage pumping chambers on opposite sides of the enlarged diameter portion of the piston. The three pumping chambers are interconnected by passage means to an inlet and outlet to provide a sequential reduction in pressure. A single drive unit may be connected to a plurality of pumping units for reciprocating the piston in each pumping unit.Type: GrantFiled: May 31, 1995Date of Patent: May 27, 1997Assignees: Commonwealth Scientific and Industrial Research Organisation, Fuji Seiki Inc.Inventor: Eckhard Bez
