Publication number: 20240140204Abstract: A method for operating a current collector and a current collector are provided for transferring energy from a conductor rail to a rail vehicle. The current collector includes a contact pressing device having a sliding piece which forms a sliding contact surface. A contact pressing force acts on the sliding piece, as the sliding piece is moved relative to the conductor rail. The current collector further includes a measuring unit having a measuring device, at least one sensor of a sensing device of the measuring device being disposed on the contact pressing device and/or adjacent to the contact pressing device. A measured value of the contact pressing device is registered by means of the sensing device. The measured value is processed by a processing unit of the measuring device and a parameter describing an operating state of the current collector and/or the conductor rail is determined.Type: ApplicationFiled: March 10, 2021Publication date: May 2, 2024Inventor: Daniel Pfeffer

Publication number: 20060011562Abstract: A filtering system used on a meat injection machine that injects pickling into meat products. The filter consists of a tank and a first and second rotary filter. The first rotary filter uses a wedge wire wound cylinder and augers having flutes that rotate to catch and push away solid particles toward the second filter. The second filter then uses more wedge wire in a whirlpool effect to ensure all solid materials and foam are in the outside of the filter. Injector fluid is then taken from the center of the inside volume of the second filter to be used in injection needles.Type: ApplicationFiled: September 30, 2005Publication date: January 19, 2006Applicant: TOWNSEND ENGINEERING COMPANYInventors: Matthew SAWHILL, Daniel PFEFFER
