  • Patent number: 10615519
    Abstract: A connecting terminal having an insulating housing, a conductor insertion channel extending toward a conductor insertion axis with an at least partially circumferential conductor channel wall arranged coaxially to the conductor insertion axis, and an actuation channel disposed adjacent to the conductor insertion channel. A leg spring bent in a U-shape has a contact leg, a clamping leg and a spring bow. A push button is adapted to be received in the actuation channel in a longitudinally displaceable manner. The contact leg is mounted on the bus bar, and a clamping edge of the clamping leg forms a spring clamp connection with a contact region of the bus bar for clamping an electrical conductor inserted in the conductor insertion channel. An actuation axis defined by a displacement direction of the push button and the conductor insertion axis are aligned with each other at an angle of 5° to 30°.

  • Publication number: 20180318777
    Abstract: The present invention is directed towards a liquid drink dispensing apparatus. The apparatus comprises a gas generating component and a liquid drink dispensing component. The generated gas is supplied to the liquid drink dispensing component which infuses the generated gas into a liquid drink prior to dispensing the gas-infused liquid drink. The advantage of using a gas generating component is that the gas can be created on-site and no bottled gas needs to be used. This obviates the problems associated with purchasing, storing, using and replacing gas cylinders.

  • Patent number: 9855699
    Abstract: A filtering device (100) for highly viscous media comprises at least one screen plug (10) which is movably arranged in a screen plug bore (27) of a housing (20) and which has at least one screen cavity (11, 12), a filter element (11.7) lying in said screen cavity. The screen cavity (11, 12) narrows to a funnel section (11.6) in a rear region when viewed in the flow direction, said funnel section opening into at least one screen plug outlet channel that opens upstream of the housing outlet channel (24, 25) in the production position. According to the invention, the screen plug outlet channel comprises an inlet zone (11.1, 11.2), at least one deflecting point (11.3), and an outlet zone (11.2, 12.2). The intake zone (11.1, 12.1) extends from an edge region of the funnel section (11.6), and the outlet zone (11.2, 12.2) is designed as a groove that extends on the outer face of the screen plug (10, 10?) and/or on the inner face of the screen plug bore (27).

  • Patent number: 9742247
    Abstract: An electric motor for driving a motor vehicle component, such as a fan motor for cooling cooling water, has a thermal fuse with a contact spring. The contact spring has attached ends that are connected to a conducting path section between which an interruption point is formed. The springy ends of the contact spring are in soldered contact with each other in a spring-biased manner. The thermal fuse is a fuse module with a plastic support in which the conducting path sections are partially embedded in such a way that the contact spring lies in a window opening in the support. Terminals of the conducting path sections protrude from the plastic support.

  • Patent number: 9364778
    Abstract: The invention relates to a filtering device for highly viscous fluids, having at least two parallel screen plungers which are arranged in a displaceable fashion in screen plunger bores of a housing and which have in each case at least one screen cavity in which at least one filter element is arranged, wherein the housing has an inflow opening from which, on the untreated side, at least one flow duct leads to each screen plunger bore, and the housing has at least one flow duct which, on the clean side, leads from each screen plunger bore to an outflow opening. On the untreated side and/or on the clean side, in each case one common flow duct leads rectilinearly along both screen plunger bores and, in a production position, tangentially intersects the screen cavities.

  • Patent number: 8640881
    Abstract: The invention relates to a screen changer in a system that processes flowable plastic. The screen changer includes an element, such as a portafilter, that is movable between two positions; two hydraulic pumps that effect position change of the screen changer; and a motor that operates both pumps. One pump provides greater flow volume and the other provides a lower flow volume, but with greater pressure. A non-return valve in the supply line to the hydraulic cylinder controls flow to the cylinder that moves the movable element between positions. The volume pump is used to move the movable element when resistance to movement of the screen is low and the high-pressure pump to move the element when resistance is high. The non-return valve selectively enables or interrupts flow from the pumps to the hydraulic cylinder. The screen changer allows use of a non-pressurized hydraulic fluid reservoir.

  • Patent number: 8632355
    Abstract: The invention describes a spring-loaded connection with a busbar piece and a bent clamping spring, which has a bearing limb, a spring bend adjoining the bearing limb and a clamping limb which adjoins the spring bend opposite the transition between the bearing limb and the spring bend. The clamping limb is aligned with the busbar piece so as to form a clamping point for an electrical conductor. An actuating lug extends away from the clamping limb. The actuating lug extends from the clamping limb past the bearing limb into an actuating region located behind the bearing limb, when viewed from the clamping limb in the direction of the bearing limb. The actuating lug has, in this actuating region, an abutment for an actuating element which can be arranged in the actuating region between the bearing limb and the abutment.
