Patent number: 10156504Abstract: An apparatus for optical in-situ gas analysis includes: a housing; a measuring lance a first end connected to the housing and a second end projecting into the gas to be measured; a light transmitter that is arranged in the housing and whose light is conducted into the measuring lance and is reflected by a reflector arranged at the second end onto a light receiver, and the optical path defines an optical measurement path within the measuring lance; and, an evaluation device for evaluating received light signals of the light receiver. In order to be able to reduce the consumption of test gas, the measuring lance has an outer tube, with the outer tube having openings for the gas to be measured. The openings can be closed by at least one seal for the test phase, with the seal searingly closing the openings by the enlargement of its volume.Type: GrantFiled: April 11, 2017Date of Patent: December 18, 2018Assignee: SICK AGInventors: Florian Brüchig, Ingo Schiffler, Jürgen Kaufmann

Patent number: 8749788Abstract: The invention relates to an improved optoelectronic apparatus for optical gas analysis by means of which the interfering influence of the particles contained in the gas is reduced with regard to the intended measurement. For this purpose the optoelectronic apparatus in accordance with the invention has a light transmitter and a light receiver which define an optical measurement path including a measurement volume between one another. The received signals of the light receiver can be evaluated in an evaluation unit, to ultimately obtain the desired information therefrom, for example, the concentration of a specific gas content. In accordance with the invention an ionizer is further provided which is arranged upstream of the optical measurement path. The ionizer causes an ionization of the undesirable particles, i.e. e.g. the dust particles, smoke particles or such like aerosols so that the ionized particles can be deflected by electric fields or also magnetic fields by means of an ion acceleration apparatus.Type: GrantFiled: May 31, 2011Date of Patent: June 10, 2014Assignee: Sick AGInventors: Jürgen Kaufmann, Frank Nuber, Michael Overdick, Rolf Schiffler

Patent number: 8657591Abstract: An engine pump assembly (1), particularly a main coolant pump, composed of a housing (4) of a rotary pump with delivery elements arranged therein, a heat barrier part (6), a motor part (5) which drives the delivery elements, and force transmitting connecting elements (7) between a housing flange (8) of the housing (4) of the rotary pump and a flange (21) of the engine part (5). For faster and more reliable assembly and disassembly, the housing flange (8) is provided with receptacles (12) over at least half of its periphery for the arrangement of screw heads (13, 15) of the connecting elements (7), which screw heads (13, 15) are held in a bayonet-like manner in the receptacles (12).Type: GrantFiled: March 19, 2010Date of Patent: February 25, 2014Assignee: KSB AktiengesellschaftInventors: Harald Hartmann, Uwe Bruhns, Ralf Graber, Bernhard Brecht, Juergen Kaufmann

Patent number: 7414703Abstract: A method and apparatus for determining a range of sight which are capable of monitoring and correcting the operability of the instrument. A light emitter directs an emitted light beam to a measurement zone and a light receiver receives a received light beam from the measurement zone. The emitted light beam and the received light beam cross each other in the measurement zone. A deflector deflects at least a portion of the emitted light beam downstream of the measurement zone along a light transmitting path and directs the portion of the emitted light beam into the received light beam at a side of the measurement zone opposite from the light receiver. An optical shutter intermittently closes the light transmitting path in a temporally controlled manner.Type: GrantFiled: December 11, 2006Date of Patent: August 19, 2008Assignee: Sick Maihak GmbHInventors: Juergen Kaufmann, Ingo Schiffler, Klaus Smetana
