  • Patent number: 10974385
    Abstract: Movable elements of a machine are moved by a control device of the machine by controlling drives of the machine. To monitor the movement of the movable elements for collision with each other or with a stationary element, two monitoring devices check, independently from each other, using a computer program, whether there is a risk of collision in the working space. Depending on whether the monitoring devices detect a risk of collision or not, they intervene, independently from each other, in a corrective manner, in the control of the drives or not, and/or independently emit an alarm message or not. The two computer programs are designed in a diverse manner. The two monitoring devices differ from one another. One monitoring device is identical to the control device, while the other monitoring device is embodied as an industrial PC with a data link to the control device.

  • Publication number: 20210080927
    Abstract: A numerical control system determines iteratively a group of position setpoint values for axes of a production machine based on presets. When no risk of a collision of one moved element with another element exists, the group of position setpoint values is stored in a buffer store. Another already stored group of position setpoint values is read from the buffer store which then controls the axes and moves the element along a path defined by the sequence of the groups of position setpoint values. This process continues for as long as no risk of a collision exists. If a risk of a collision exists, the numerical control system brings the axes to a standstill. Previously unknown real time events are considered only in the determination of the groups of position setpoint values not yet stored in the buffer store. The groups of already stored position setpoint values are not altered.

  • Patent number: 6457458
    Abstract: An arrangement for forwarding fuel from a fuel tank to an internal combustion engine includes a fuel-forwarding device having a suction side and an elevated pressure side. An inlet conduit connects the suction side with the fuel tank, while a fuel-forwarding conduit forwards the fuel from the elevated pressure side. A fuel filter housing for accommodating a fuel filter surrounds the fuel-forwarding device. The fuel filter housing is connected with the fuel-forwarding device in an electrically conductive manner. One of the fuel filter housing and the fuel-forwarding device is connected to a location that is at a predetermined electrical potential.

  • Patent number: 6415771
    Abstract: An apparatus for pumping fuel from a tank (10) to the internal combustion engine (12) of a vehicle has a jet pump (24), which supplies fuel returning from the internal combustion engine (12) in a return line (22) together with fuel disposed in the tank (10) into a storage reservoir (14) of a fuel delivery unit (16). The invention proposes embodying a restriction (23) for the fuel between a seat edge (31) and a spring-loaded ball (32). In addition, inlet openings (39) for the fuel disposed in the tank (10) are embodied in the vicinity of the restriction (23). The apparatus has the advantage of a high delivery output, a compact design, and a delivery onset even when there are relatively low return quantities. Furthermore, fuel is prevented from flowing back into the return line (22).

  • Patent number: 6293256
    Abstract: The fuel delivery device (12) has a receptacle (16) arranged in a storage tank (10) and a delivery unit (20) delivering fuel from the receptacle (16) to the internal combustion engine (14) of a motor vehicle. Further, there is provided at least one suction jet pump (40) which delivers fuel from the storage tank (10) into the receptacle (16). The suction jet pump (40) is fastened to an upper edge area (17) of the receptacle (16) as a separate constructional unit. The suction jet pump (40) is formed by a constructional unit having a propelling nozzle (41), a connection (43) for a propelling line (44), which connection (43) opens into the propelling nozzle (41), a mixing pipe (42) following the propelling nozzle (41), and a connection (45) for a suction line (46), which connection (45) opens into the mixing pipe (42).
