Patent number: 11898569Abstract: A fan includes a hub configured to be driven by motor to rotate about a fan rotational axis, blades that protrude radially from the hub and a band that surrounds the rotational axis and connects the tips of the blades. The band includes structurally-reinforcing ribs that protrude from the hub-facing surface of the band. A rib is disposed between respective tips of each pair of adjacent blades. Each rib bridges a knit-line of the band, and has a circumferential dimension that is at least 40 percent of a distance between the respective tips of the adjacent blades.Type: GrantFiled: April 6, 2021Date of Patent: February 13, 2024Assignees: Robert Bosch LLC, Robert Bosch GmbHInventors: Markus Liedel, Alain-Bernard Isel, Ray Cote, Eugen Stockmann, Serge Nako

Publication number: 20130328229Abstract: A process is described for producing an injection moulding (300) with the aid of an injection moulding device (100), where a charge (301) is injected into a cavity (200) of the injection moulding device (100) and is foamed with the aid of a ventilation cycle (132, 142, 152). In this process, a displacer element (130, 140, 150) restricted to a selected section (220, 240, 260) of the cavity (200) is introduced into the cavity (200), and the charge (301) is injected into the cavity (200) with the displacer element (130, 140, 150) arranged therein. In a subsequent ventilation cycle (132, 142, 152), the displacer element (130, 140, 150) is then moved out from the cavity (200) in order to foam the charge (301) in the selected section (220, 240, 260) of the cavity (200).Type: ApplicationFiled: June 21, 2011Publication date: December 12, 2013Applicant: ROBERT BOSCH GMBHInventors: Thomas Helming, Markus Liedel
