  • Patent number: 8114037
    Abstract: There is provided a non-invasive pulsation and counterpulsation medical treatment apparatus for treating reduced cardiac output in heart patients. A flexible cuff is passed over the patient's lower body and/or extremities, and is attached a hydraulic actuator. Through a mechanical linkage, the actuator sequentially tensions and releases the cuff, thereby sequentially compressing and releasing pressure on the patient, and thereby augmenting the patient's blood pressure. The actuator includes a hydraulic cylinder that axially extends and retracts a shaft. A curved plate on the apparatus supports the patient's body or extremity in a fixed position during the treatment. A pressure sensor in the cuff transmits pressure data to an operator or electronic processor. Based on physiological data continuously obtained from the patient, various treatment parameters may be changed during the patient's treatment by an attending clinician or by a computer processor controlling the treatment.

  • Patent number: 7946348
    Abstract: A downhole rotation tool comprises a housing rotatable and axially slideable in relation to a gear shaft. The gear shaft is located interior of the housing. A tube gear is located intermediate the gear shaft and the housing. Helical threading on the gear shaft exterior interacts with helical threading interior of the tube gear to impart rotation of the tube gear upon linear movement of the gear shaft. A gear face at a lower end of the tube gear interacts with a corresponding gear face on the housing. Face gear teeth of the tube gear and the housing include axially-aligned engaging surfaces to rotate the housing in a preferred direction on downward stroke of the gear shaft and include inclined slip surfaces to allow relative rotation of the housing gear face and the tube gear face upon upward stroke of the gear shaft.

  • Patent number: 7820045
    Abstract: A sludge filter is comprised of a mesh filter media secured to a support net. The support net includes a front surface adjacent the filter media and a rear surface opposite the filter media, the rear surface having a plurality of outwardly extending nodes to define flow channels for horizontal and vertical fluid flow intermediate the net and a container surface. The sludge filter is attached directly to the walls or floor of a container. In a preferred embodiment a border of the sludge filter comprises one part of a two-part fastener system with a second part of the two-part fastener system attached to a container along the perimeter of the filter coverage area, so that the filter medium may be removably attached to the container.
