  • Publication number: 20230417314
    Abstract: A contaminant-flushing machine for removing contaminants from a container, such as an engine transmission, air-conditioner coil, or transmission cooler, which includes hoses for coupling to the transmission cooler and a pump for circulating fluid through the hoses and the transmission cooler, the flushing machine being configured to terminate all circulating of fluid when a pressure drop is detected during times when the fluid is circulating only in the primary flow direction, but not when the flow direction is being reversed.

  • Patent number: 9289559
    Abstract: The present invention relates to an electronically assisted injection device adapted to inject doses of a drug from a held cartridge. The injection device may include a first rotational sensor (40) coupled to a driver (6) for sensing a dose setting and a second rotational sensor (50) coupled to a dosing member (8) for sensing an expelled dose. A third axial sensor (60) provides information relating to the axial position of the driver (6). A control circuit is adapted to determine the end of dosed state based on data from the first, the second and the third sensors (40, 50, 60). The injection device may also include an arrangement for determining fluid ingress into the interior of the injection device. The arrangement includes an electrically non-conductive surface portion (63) disposed on a first component (6) and an electrode assembly (62a, 62b, 62c) disposed on a second component (80) wherein the first component (6) and the second component (80) moves relative to each other during operation.

  • Patent number: 7510662
    Abstract: A contaminant-flushing machine for removing contaminants from a container, such as an engine transmission, air-conditioner coil, or transmission cooler, which includes hoses for coupling to the transmission cooler and a pump for circulating fluid through the hoses and the transmission cooler, and a fluid filter having a reduced tendency towards causing vaporization of the fluid. Also included in the contaminant-flushing machine is an automatic aeration system for injecting air into the circulating fluid at predetermined intervals. Additionally, a reverse flow piping circuit is included to permit automatic and electric manipulation of the flow direction of fluid through said transmission cooler while at the same time not altering the direction of flow of fluid through the pump. The flow reversals are repeated with a cycle of three (3) seconds in one direction followed by a flow in the other direction of one-fourth (¼) of a second, thereby creating an overall flow of fluid primarily in one reverse direction.
