Title: Extractor for towed linear antenna or the like
Inventor: BOREL CHRISTOPHE
IPC: H02G1/10
Filed: 2004-07-15
Abstract: The present invention relates to a device for the automatic hauling of very long elongate objects. This device in particular allows very long tubular objects of relatively flexible and delicate structure such as, in particular, underwater cables, pipes or alternatively linear sonar antennas of the "streamer" type to be handled. The device chiefly comprises traction means consisting of at least two running strips with rough surfaces which are pressed on each side of the object and drag it along in a traction movement and gripping means which constantly keep the running strips pressed against the object in order to ensure good adhesion. Another subject of the invention is means for actuating the traction means and the gripping means in a coordinated manner so that the object that is to be hauled experiences continuous traction throughout the hauling operation. The device according to the invention has the advantage of being mounted on a stationary chassis and therefore of not requiring an operating area. It is thus particularly intended for vessels where the available space is restricted, such as submarines.
Patent CA-2535628-A1 (CA)
Inventor: COTE ANTHONY J
IPC: F24F11/75
Filed: 2006-01-31
Abstract: An improved air volume regulator used in HVAC operating at a static pressure of 25 pa. (0.1"w.g.) having a pair of opposing gates facing into the airflow and a V  shaped deflector positioned to form two constricting passageways. Air flowing through the passageway generates a light vacuum at its throat and combined with the static pressure differential across the gates urges them towards the deflector and constricts the airflow.  A counterbalance spring cooperating with a concave cam and cam follower applies a resisting bias on gates such that the airflow in the regulator remains constant under varying inlet conditions. A variable spring rate mechanism permits the adjustment of the airflow rate over the full operating range using a single counterbalance spring. A cable driven "limited torque" flywheel controls the air volume regulator's propensity to pulsate under unstable inlet airflow conditions.

Patent CA-2550423-A1 (CA)
Title: Apparatus and methods for actuation
Inventor: GROSSART STUART JAMES CAMERON
IPC: F15B21/14
Filed: 2004-12-16
Abstract: There is disclosed an actuator (5) having an actuator chamber (6) and actuator piston (9) therein defining an extend chamber (10) and a retract chamber (7) separated from the extend chamber by the actuator piston. A first fluid pump (A) is in fluid communication with the extend chamber and the retract chamber and is arranged to transfer therebetween volumes of fluid substantially equal in magnitude to changes in the volume of the retract chamber resulting from movement of the actuator piston within the actuator chamber. A second pump B  connected to the extend chamber and to an accumulator (17) allows the differential volume between the extend and retract chambers to be displaced into the accumulator at a pressure. Stored accumulator fluid pressure enables pump B to be back-driven so that it behaves as a motor whenever the pressure in conduit 15 is less than in conduit 16. A pre-charge (20) unit pressurises the system until full mass counterbalance of the suspended load is achieved.  In this state little or no input power from the servo motor (via pumps A & B) will be needed and significant energy savings can be made.

IPC: A61M5/00
Filed: 2005-02-11
Abstract: The present invention embodies a method and an injector adapted to incorporate this method, for keeping a patient's vein open during an intravenous contrast injector procedure without injecting a saline solution from a separate syringe. The injector includes a controller having a programable software module to allow an operator to configure the injector to push some contrast media fluid through an injection site and then retract a plunger drive ram. A  syringe is adapted to allow a patient's blood pressure to move the syringe plunger back towards its starting position, thus enabling a patient's blood to pass through the injection site. Alternatively, the syringe is adapted with an elastic plunger which as it enlarges and contracts facilitates fluid communication through the injection site. Additionally, the plunger drive ram can be adapted to gradually pull as well as push the plunger, thereby causing fluid to flow across the injection site.
