Title: Opioid Detection
Inventor: ELOUARD BENCHIKH
IPC: G01N33/94
Filed: 2015-12-21
Abstract: An immunoassay method is described which detects O-desmethyltramadol (O-DSMT, ODT) using an antibody against O-desmethyltramadol which has a cross-reactivity of less than 5% to tramadol and N-desmethyltramadol. This enables an assay of high sensitivity and specificity avoiding false positive results. The unique antibodies incorporated in the immunoassay method can be combined with antibodies which detect mitragynine to provide an assay which increases the possibility of detecting the commonly found drug combination of O-desmethyltramadol and mitragynine.

Title: Magnetic bearing and vacuum pump with such a magnetic bearing
Inventor: ENG KEEN KHOR
IPC: F16C32/04
Filed: 2018-01-09
Abstract: Disclosed is a magnetic bearing 38 for supporting a rotating element with a non-rotating first magnetic element 42 that is in mutual repulsion with a rotating second magnetic element 44. At least one of the magnetic elements comprises a permanent magnetic made of a magnetic material whose relative magnetic permeability a first temperature is less than at a second higher temperature. The first temperature may be about 20ºC (ambient). The second temperature may be the maximum temperature of the rotating element. The magnetic material may be a neodymium magnet with a working temperature of 120-200ºC. Also disclosed is a turbomolecular vacuum pump 10 with said magnetic bearing. The use of neodymium magnets in a turbomolecular vacuum pump allows the magnetic strength for the rotor component to decrease as the rotor thermally expands. A roller bearing 32 is preloaded by offsetting the magnets of the magnetic bearing, but as the rotor thermally expands the preloading force is increased. The weakening magnetic strength of the neodymium somewhat mitigates this increase, meaning less force and thus less wear is experienced by the roller bearing.
