Abstract: A patient controlled liquid drug administration device (10)comprises a reciprocating pump (12) having an inlet connectable to a source of a pressurized liquid drug, and an outlet connectable to the patient. A clamp (38) rotates between closed and open positions respectively blocking and enabling pump outflow. A plunger (48) above the pump has an end contacting a movable wall (26) of the pump and is movable between raised and lowered positions. A button (50) above the plunger moves between extended and depressed positions, and has a ledge that engages the clamp when the button is moved to the depressed position and moves the clamp to its open position. A compression spring (52)is disposed between the plunger and the button. A spring catch (60) engages a detent in the button (50) when the button is moved to its depressed position and holds the button there until released by a catch release (62) on the plunger that disengages the spring catch from the detent in the button when the plunger (48) is moved to its lowered position. A removable tab permits easy, rapid priming of the pump by holding the clamp in its open position regardless of the position of the button, and by holding the button in its depressed position regardless of the position of the plunger.

Abstract: A method and an arrangement for respiratory support for a patient and an airway prosthesis is disclosed. The spontaneous breathing of the patient is recorded with sensors and an additional amount of oxygen administered by means of a jet gas flow at the end of a lung inhalation process. The exhalation process of the patient can be retarded by a counter-current to prevent a collapse of the airways. There is an arrangement, comprising an oxygen pump connected to an oxygen source and an airway prosthesis, which may be connected by means of a catheter. A controller activates the oxygen pump. The airway prosthesis has a tubular nozzle body with a connector for the catheter, whereby two of the sensors are provided on the nozzle body. The airway prosthesis and the integrated or introduced jet catheter are of such a size that the patient may breathe and speak freely.

Granted: 2011-11-01
Abstract: This invention relates to a seal for sealing a freight container. The seal includes, in its in-~use configuration, a shaft (18) and heads (20) on opposite ends thereof. It includes also an electronic circuit (40) including a radio frequency identification (RFID) transmitter (42) and sensing means (44, 46) for sensing severance of the shaft (18). Severance of the shaft (18), if sensed by the sensing means (44, 46), is detectable by interrogation of the RFID transmitter (42) via a compatible interrogation device. A basic embodiment of the seal comprises parts made mostly of a non-conductive, vulnerable material. Should operational requirements so dictate, additional parts are provided for effectively, in the in-use configuration of the seal, reinforcing the vulnerable parts to yield a tamper resistant seal which still may be interrogated to determine integrity of its shaft. Other embodiments of the seal permit also interrogation to determine the integrity of another part of the seal.

Title: Field marker for agricultural implement
Inventor: HUNDEBY DAVID
IPC: A01B61/04
Filed: 1998-10-30
Granted: 2007-07-31
Abstract: A field marker for mounting on an agricultural implement includes an elongated arm adapted to project outwardly laterally of the implement when in its operating position and is adapted to carry a field marking device at its outer distal end for making a score mark on the ground. A mount for the arm at an inner proximal end thereof allows pivoting of the arm about first and second transverse axes whereby to allow the arm to swing upwardly and downwardly about the first one of said axes when operating on uneven ground while also allowing the arm to swing around the second one of said axes from its outwardly projecting operating position into another position. The arm includes inner and outer arm sections secured together by a folding joint to permit the inner and outer arm sections to be folded into juxtaposition with one another and brought into the transport position. An extensible actuator effects relative rotation of the inner and outer arm sections, and a mechanism interacts with the inner and outer arm sections and the actuator such that as the inner arm section is pivoted through a selected angle, the outer arm section is pivoted about said folding joint relative to the inner arm section. A breakaway link on the arm permits the arm to swing as a whole relative to the mount about the second axis away from its outwardly projecting operating position when an obstacle is encountered and a predetermined force on said arm has been exceeded. The breakaway link has a resetting device associated therewith for returning the arm to the operating position once the obstacle has been cleared.

Title: Slide clamp
Inventor: BOYNE-AITKEN DAVID E
IPC: F16K7/06
Filed: 2004-11-19
Granted: 2012-03-06
Abstract: A slide clamp includes a slot formed in a plate though which a fluid tube is mounted. The tube may be moved to a flow section of the slot or to an occluding; section of the slot. Interconnecting the flow and occluding sections is a pinch zone in which the slot is narrower than the occluding section. Because of this narrow slot, the pinch zone resists movement of the tube from either the occluding or the flow sections into another section. The pinch zone includes a pair of curved beams that are formed as a result of apertures formed in the plate at locations laterally outward from the slot of the pinch zone. As a tube is forced from the occluding section to the flow section the curved beams flex outwardly permitting the tube to pass. However, if enough force is not applied to the tube, it will not overcome the curved beams and they will stop movement of the tube. After the tube has passed, the curved beams resiliently return to their rest position once again providing a stop. The beams are symmetrically shaped and will permit movement of the tube in either direction. The apertures also provide identification markers for the slide clamp.

Abstract: A stray voltage detection and isolation system. The stray voltage detection portion of the system includes a water delivery system electrically isolated from an electrical transmission system of an electric utility. Meters measure an electrical characteristic between a first test-point that is electrically connected to the water delivery system and a plurality of second test-points. The second test-points are at earth grounds at locations electrically connected to the first test-point. The location of a source of stray voltage can be determined by evaluating differences in the measured electrical characteristics. The stray voltage isolation portion of the system electrically isolates a water delivery system. A controller maintains an air gap between a water source and a first storage tank or between the first storage tank and a second storage tank. The second storage tank provides the electrically isolated water.
