Patent number: 11588372Abstract: An electrical drive unit has a housing having a metal pole housing, which accommodates a stator and a rotor, and a separately produced electronic housing which axially adjoins the pole housing and accommodates an electronic unit. At least one contact element is integrated inside the electronic housing and forms, via at least one ground pin, an electrically conductive connection between the electronic housing and the pole housing to establish a ground connection. An open flange and a cylindrical circumferential wall are formed on the pole housing, against which circumferential wall the at least one ground pin radially bears in a resilient manner, and the at least one ground pin has a side surface facing the circumferential wall, wherein a bearing contour is formed on the side surface and bears against the circumferential wall only in an approximately punctiform manner with respect to an axial direction and/or a circumferential direction.Type: GrantFiled: July 21, 2020Date of Patent: February 21, 2023Assignee: Robert Bosch GmbHInventors: Eric De La Chaux, Fengmei Cheng, Helmut Meier, Jan Wilhelm

Patent number: 4792229Abstract: A device for mixing gas and/or vapor streams including liquid components dispersed therein in which the incoming product streams which have been crudely mixed with quench gas, are fed as a single total stream through a collecting plate which covers the reactor cross section, with the streams being collected on the concave side of the plate and passing through it. The streams pass through a mixing pipe which adjoins the outlet of the collecting plate, and the streams further pass through an outer pipe which is configured so as to bring about a reversal of the flow direction. The streams then pass into the space above a distributor device, and are uniformly distributed over the reactor cross section, along with liquid components collected on the distributor, onto a catalyst bed disposed below the distributor.Type: GrantFiled: June 30, 1987Date of Patent: December 20, 1988Assignee: Veba-Oel Entwicklungs-Gesellschaft mbHInventors: Heinz Frohnert, Hansjuergen Ullrich, Helmut Meier

Patent number: 4346203Abstract: An emulsifier for the preparation of polymers comprising more than 50 percent by weight of an alkali metal salt of polysulphonic acid of alkane of medium chain length is disclosed. The emulsifier is useful in forming emulsions of polymers especially thermoplastic polymers and in particular polymers of vinyl chloride. It is useful in vinyl chloride polymerization and co-polymerization to form an emulsifier composition having improved transparent and antistatic properties. The polymer can be added before, during or after polymerization. When added after polymerization it provides improved properties to a calendered object obtained from the polymer.Type: GrantFiled: July 30, 1980Date of Patent: August 24, 1982Assignee: Bayer AktiengesellschaftInventors: Adolf Schmidt, Helmut Meier, Gunther Schedrat, August Bockmann

Patent number: 4223259Abstract: Apparatus for supporting a body on a carrier in a desired angular position while the carrier is mounted on a moving base, such as a ship, includes an electrically operated drive for angularly moving the carrier relative to the base about a normally horizontally extending axis. The control device for controlling the drive includes a first signal generator which senses the rate of angular movement of the carrier in a plane perpendicular to the afore-mentioned axis and generates a first signal indicative of the sensed rate. A second signal generator includes a mercury switch and generates a second, constant, D.C. signal indicative of the absence or presence of a predetermined angular position of the mercury switch in plane perpendicular to the axis. A circuit connected to the signal generators and the drive transmits to the drive an electrical operating signal in response to the first and second signals and thereby causes the mercury switch to be moved by the drive into its predetermined angular position.Type: GrantFiled: July 5, 1978Date of Patent: September 16, 1980Assignee: Dornier System GmbHInventors: Klaus Ernsberger, Helmut Meier
