Publication number: 20240132293Abstract: A feeding screw machine for feeding a processing screw machine comprises a housing with at least two housing bores formed therein and screw shafts rotatably arranged in the at least two housing bores. The at least two housing bores and the at least two screw shafts define a free volume in a respective cross-sectional plane, which decreases monotonically at least in some regions for continuous compression of a material in a conveying direction. This enables an improved supply of material with a low bulk density.Type: ApplicationFiled: January 28, 2022Publication date: April 25, 2024Applicant: Coperion GmbHInventors: Stefan HUBER, Markus SCHMUDDE, Svetlana MARINOVA, Ralf KÜHN, Kai KLUGE, Oleg RUDI, Dirk KYRION, Robert KESSLER, Leonid LIBER, Marina MATTA, Jochen SCHOFER

Patent number: 9068585Abstract: A retainer with an axial passage for receiving a format part is disclosed. The retainer includes several clamping tongues facing in the direction of the format part, the clamping tongues being angularly aligned against an outer lateral surface of the format part and being elastically deformable. The format part is held stationary in a first movement direction by the clamping tongues when its outer lateral surface is contacting the clamping tongues and whereby the format part is movable and/or guidable in a second movement direction, the second movement direction being opposite to the first movement direction. Furthermore the retainer includes at least one adjuster, wherein the surface contact between the respective clamping tongues and the format part is released upon actuation and/or upon a defined alignment of the at least one adjuster.Type: GrantFiled: September 19, 2012Date of Patent: June 30, 2015Assignee: Krones AGInventor: Robert Kuehn

Patent number: 8290726Abstract: A Built-In Test (BIT) for a photoconductive photodiode is performed using the health or characteristics of the photodiode's parasitic capacitance as a “proxy” for the health or characteristics of the photodiode itself. A failure or degradation of the photodiode manifests as a similar failure or degradation of the parasitic capacitance. Under normal operating conditions, the photoconductive photodiode responds to incident photons from a target by generating a photocurrent signal at its cathode. A processor processes the signals from one or more photodiodes to evaluate characteristics of the target. To perform the BIT, a time-varying voltage signal is applied at the photodiode's anode. This signal is coupled through the parasitic capacitance to produce a test current signal at the photodiode's anode. The processor processes the signal to evaluate the health or characteristics of the parasitic capacitance and thus the photodiode.Type: GrantFiled: April 28, 2010Date of Patent: October 16, 2012Assignee: Raytheon CompanyInventors: Richard A. Schmidt, Mitchell O. Perley, Robert A. Kuehn

Patent number: 6389950Abstract: A manually controlled lifting device is provided including a pneumatic lifting drive, a lifting member, a load carrying means, a pressure source, a pressure line, a flow control device, a pneumatic pressure switch and a vent drive. The lifting member is arranged on the pneumatic lifting drive and is a load transmitting component of at least two parts. The load carrying means is attached to the lifting member for carrying a load. The pressure line has a first end and a second end where the first end is in communication with the pressure source and the second end is in communication with the pneumatic lifting drive. The flow control device is in communication with the pressure line and integrated between the two parts of the load transfer component and the pressure source. The flow control device automatically varies a cross section of flow in the pressure line in relation to a load acting on the load carrying means.Type: GrantFiled: August 16, 2000Date of Patent: May 21, 2002Assignee: Mannesmann AGInventors: Robert Kühn, Wolfgang Bittenbinder

Patent number: 6276216Abstract: A force gage for measuring a tensile force in a pneumatically-operated device, includes a parallelogram linkage having a pair of longitudinal arms in spaced-apart parallel disposition, and a pair of transverse arms in spaced-apart parallel disposition and hingedly interconnecting the longitudinal arms, with a first one of the longitudinal arms being acted upon by a tensile force and movable by the tensile force in the direction of the tensile force, whereby the pair of longitudinal arms is oriented in a direction parallel to the tensile force. A probe is positioned between the transverse arms and securely fixed to a second one of the longitudinal arms for generating a pneumatic pressure signal commensurate with the tensile force. The probe has a casing and a sensing element which projects out of the casing and is acted upon in dependence on the tensile force by a force-applying structure which may be either the first longitudinal arm or one of the transverse arms.Type: GrantFiled: November 29, 1999Date of Patent: August 21, 2001Assignee: Mannesmann AGInventors: Wolfgang Bittenbinder, Robert Kühn

Patent number: 5696657Abstract: Laser range finder circuitry including an avalanche photodiode detector, a capacitor for storing a detector bias voltage, and a transimpedance amplifier for amplifying the detector signal. The capacitor is charged in response to a first control signal by a circuit employing first and second field effect transistors and is discharged in response to a second control signal by a circuit employing a third field effect transistor. An overload protection circuit including a single diode is provided to accommodate excessive charge created by backscatter upon initial laser firing. A temperature sensor is further provided to develop a temperature signal which may be monitored to adjust the detector bias voltage and other parameters so as to permit use of an associated laser range finder over a wide range of temperatures.Type: GrantFiled: June 2, 1995Date of Patent: December 9, 1997Assignee: Hughes ElectronicsInventors: Charles E.

Patent number: 5691808Abstract: A laser range finder receiver for detecting a return pulse and providing an output signal indicative thereof and a single-chip microcontroller for controlling receiver operation and, in particular, for automatically recalibrating the receiver. The receiver is responsive to up and down current control signals from the microcontroller to adjust the bias of an APD photodetector. An offset voltage and receiver false alarm rate are monitored with no light on the photodetector while a calibration voltage is adjusted to recalibrate the receiver. The microcontroller further monitors photodetector temperature via a temperature sensor, and can perform APD bias adjustment and receiver recalibration in response to temperature changes, providing operation over a wide temperature range.Type: GrantFiled: July 31, 1995Date of Patent: November 25, 1997Assignee: Hughes ElectronicsInventors: Charles E.
