Patent number: 11604090Abstract: A belt conveyor conveys discrete articles. The belt conveyor includes: a conveyor frame having a top side, a bottom side, and a length extending in the conveying direction for the discrete articles; a conveying belt configured to revolve around the conveyor frame during operation of the belt conveyor; and a belt-guide mounted to the bottom side of the conveyor frame between the conveyor frame and the conveying belt. The belt-guide includes at least two rolling-element bearings. The inner races of the rolling-element bearings are respectively mounted on axles. The axles are parallel to each other and stationary relative to the conveyor frame. The outer races of the rolling-element bearings have direct contact with the conveying belt.Type: GrantFiled: October 11, 2021Date of Patent: March 14, 2023Assignee: BIZERBA SE & CO.

Patent number: 7323766Abstract: A sensor module, in particular for measuring an acceleration or rotational speed, having a housing base body made of a plastic material, a lead frame extending through the housing base body and having leads which have connector pins for attachment to a circuit board, a sensor system having at least one sensor chip, the sensor system being in contact with the lead frame via conductor bonds, a cover, which is connected to the base body and at least one connector pin and is made of a conductive material. A simple construction having a high shielding effect is achieved due to the fact that the conductive cover is connected to the connector pin. The cover, a lid, for example, may be contacted directly via the connector pin together with the other connector pins when the components are mounted on the circuit board. The sensor module may be molded or may have a premolded housing. The edge or a contact of the cover may be welded, soldered, glued, or pressed to a ground lead of the lead frame.Type: GrantFiled: November 4, 2004Date of Patent: January 29, 2008Assignee: Robert Bosch GmbHInventors: Kurt Weiblen, Franz Schmich, Harald Emmerich, Klaus Offterdinger, Hansjoerg Beutel, Johann Wehrmann, Florian Grabmaier
