Patent CA-2169510-A1 (CA)
Title: Actuator with Protective End Cap
Inventor: WEYER PAUL P
IPC: F15B15/28
Filed: 1996-02-14
Abstract: A fluid-powered rotary actuator for providing rotary movement between first and second external members. The actuator includes a cylindrical body with first and second ends. The body is adapted for coupling to the first external member, and a shaft extending generally coaxially within the body and supported for rotation relative thereto. The shaft having an adjustable end limit of rotation relative to the body. The shaft has an end portion adapted for coupling to the second external member to provide rotational movement between the first and second external members. An annular body insert is positioned coaxial with the body and at least partially within the body at the body first end. The body insert is formed as a separate part from the body and is adjustably rotatable relative to the body to permit adjustment of the end limit of rotation of the shaft relative to the body. The body insert is restrained by the body against axial movement relative to the body during powered operation of the actuator. An end cap is securely attached to the body at the body first end and spaced axially outward of and away from the body insert to define a compartment therebetween. An adjustment member extends through an aperture in the end cap with an interior portion within the end cap compartment in position to engage the body insert and an exterior portion accessible from the exterior of the end cap compartment. The adjustable member is adjustably movable in the aperture to apply an adjustment force on the body insert to adjustably rotate the body insert relative to the body to a selected rotational position relative to the body in order to adjust the end limit of rotation of the shaft relative to the body. The adjustment member, when not being adjustably moved in the aperture, holds the body insert to prevent its rotation from the selected rotational position relative to the body. A piston is mounted within the body and is reciprocally axially movable therein in response to selective application of pressurized fluid thereto. A torque-transmitting annular member is positioned generally coaxially within the body for movement with the piston. The torque-transmitting member drivingly engages both a grooved sidewall portion of the shaft and a grooved sidewall portion of the body insert as the torque-transmitting member reciprocally moves within the body.

Abstract: A portable heating unit having a housing with a carrying handle, the housing including a motor portion, a blower and an air intake. The housing also includes a mounting nose for receiving a hot air delivery barrel which has a double safety wall construction through  that  area  in which  flames  for  heating  air  will  be generated. A gas nozzle assembly is received either at an angle through an opening in the barrel wall or disposed concentrically within the barrel portion for introducing gas into the barrel. The nozzle assembly draws its air supply for combustion either in the back of the nozzle member and independent of the forced air supply or through the rear end of the barrel and an igniter is provided for lighting the gas by spark means. Provision is made for igniting the combustible gas at a location apart from the turbulent forced air flow and,  for safety reasons,  ignition of the combustible gasses is not possible in the absence of a forced air stream for delivering the generated heat from the barrel of the device.

Title: Cardiopulmonary bypass system for closed-chest intervention
Inventor: STEVENS JOHN H
IPC: A61M1/36
Filed: 1994-11-10
Abstract: The invention provides a system and method for establishing cardiopulmonary bypass and performing an interventional proce-dure in a patient's heart or great vessel with a minimum of arterial and venous penetrations. In one embodiment, a bypass cannula (180) configured for introduction into a patient's artery includes a blood flow lumen (188) which may be connected to a cardiopul-monary bypass system (92, 94, 96, 100).  A catheter shaft (202) is coupled to the bypass cannula, usually within the blood flow lu-men, amd has a member (216) at its distal end for performing an interventional procedure within the heart or great vessel. In a par-ticular embodiment, the catheter shaft has an expandable member such as an inflatable balloon disposed near its distal for occlud-ing the ascending aorta so as to substantially block all blood flow therethrough for a plurality of cardiac cycles. The catheter shaft has an inner lumen (212) through which cardio-plegic fluid may be delivered upstream of the occluding member to infuse cardio-plegic fluid into the coronary arteries for arresting the heart. The blood flow lumen in the bypass cannula is connected to a cardiopul-monary bypass system, which receives deoxygenated blood from the patient's venous system, oxygenates the blood, and delivers the oxygenated blood to the patient's arterial system through the blood flow lumen.

Patent CA-2180266-A1 (CA)
Title: Improved pulsed discharge systems
Inventor: WENTWORTH WAYNE E
IPC: G01N27/68
Filed: 1995-01-03
Abstract: The discharge systems of this disclosure are useful in the chemical analysis field, including identification and quantification of gaseous impurities.  The systems utilize a pair of electrodes which apply a spark across a gap between the electrodes, the spark preferably being repetitively formed.  As an inert gas flows between the electrodes, the spark creates photons of energy which are emitted and are used as described.  In alternate aspects, other particles are energized in the spark gap and subsequently surrender their energy.  Photon emission or loss of energy assists in identification and measurement of peaks eluted from a typical gas chromatograph.  The preferred inert gas is helium with or without traces of rare inert gases.

Title: Structure for supporting egr valve in engine
Inventor: TANIOKA MASATOSHI
IPC: F02B75/22
Filed: 1996-09-11
Abstract: A water passage is provided separately from an intake manifold to interconnect water jackets provided in a front bank and a rear bank of a horizontal V-type engine. An EGR valve is supported on a valve mounting seat which is provided at a front portion of the water passage. A water passageway through which cooling water flows, and a gas passageway through which an EGR gas flows, are defined in the water passage in proximity to each other. The EGR valve is cooled by cooling wind passed through a fan opening in a radiator and by cooling water flowing through the water passageway. Thus, it is possible to avoid thermal influence on the intake manifold by the EGR valve, and to cool the EGR valve without the need for special cooling means.

Title: An apparatus for the discontinuous preparation of farinaceous products
Inventor: STEIN HANS-ULRICH
IPC: A23L7/109
Filed: 1995-12-27
Abstract: Illustrated and described is equipment for the discontinuous preparation of pasta, such as spaghetti, the equipment having a portioning device to which the raw pasta is fed, a cooking chamber (1) and a draining chamber (2), the inlet and outlet of the cooking chamber (1) and draining chamber (2) being closable by valves designed as shutter flaps (3, 4). Between the cooking chamber (1) and the drainage chamber (2) is a single shutter flap which can be turned about a spindle (38). The shutter flaps at the inlet to the cooking chamber (1) and the outlet from the drainage chamber (2) can be moved across the direction of flow through the inlet and outlet, respectively. In order to reduce the complexity of the valve design without causing leakage or impairing operation, the invention calls for the flaps (3, 4) to be pressed against the respective chamber openings at the inlet (1E) to the cooking chamber (1) and at the outlet (2A) from the drainage chamber (2) at a shallow angle (.alpha.) to close the chambers (1, 2).
