Abstract: A probe for cardiac diagnosis and/or treatment has a catheter tube. The distal end of the catheter tube carries first and second electrode elements. The probe includes a mechanism for steering the first electrode element relative to the second electrode element in multiple directions.

Abstract: An improved probe for cardiac diagnosis and/or treatment includes a control handle and a catheter for insertion into the heart. The catheter has a distal end, a proximal end and at least one lumen connecting said distal and proximal ends. It also includes a flexible inner tube and an outer sheath enveloping said tube. At least one measuring electrode or ablation device is attached to the distal end of the tube. The outer sheath and the inner tube are rotatable relative to each other so that the electrode or device can be rotated within the heart without rotating the outer sheath. The sheath is also axially movable relative to the tube to selectively enclose or expose the electrode or device for use.

Abstract: A cell for electrolytic silver recovery is provided with a threaded fitting and can be connected to a conventional fluid flow fitting having a fluid flow inlet and outlet by means of a collar connecting the dissimilar threads of the fitting and the cell. The cell is connected by an electric lead to an outside source of power and contains an electrode in electrical contact with liquid in the cell and a second electrode in the form of a thin conductive coating on the interior of the cell.

Abstract: A plurality of manifold valve assemblies each including pairs of generally vertical valve cylinders each cylinder having actuator rods that are coaxial with each other, the rods being independently actuatable by their respective actuators. Each cylinder has an inlet port at its top each connected to a different supply conduit and each being connected by a crossover conduit near its lower end to the lower end of the other cylinder of the pair. One of the bottom ports of each pair is connected to a drain, thereby forming a leak detector, while the other bottom port of each pair is connected to a line supplying a clean-in-place liquid. Valve seat 45 is positioned below valve plug 40 so that it is closed by extension of actuator rod 32.

Abstract: A device for preventing leakage and spillage of fluids from a canister type oil filter during removal thereof from an engine block is in the form of an annular elastomeric sleeve having an upper end and a lower end. The upper end has an opening adapted to fit over the exterior of an oil filter. The bottom end of the sleeve has an opening of lesser diameter than that of the upper end and the body of the sleeve adjacent the lower end has smooth contours and is of increased thickness relative to the body of the sleeve. A plurality of protrusions extend inwardly from the inner surface of the shape positioned circumferentially around the shape and are located between the upper and lower ends thereof.

Abstract: A tubular plastic body of a neon tubing support has a bore terminating in a lower opening and in an opposite internally shouldered upper opening. A helical spring is installed in the bore through the lower opening and retained by a plug in the lower opening at one end of the bore and by the shoulder at the other end. A stem unit includes a shaft having a tubing engaging element on one end, and extends into the bore coaxially with the spring and terminates in an integral bulbous portion. The bulbous portion is axially slotted to define legs which can flex toward each other for clearing through the undersized top opening in the body. The bulbous portion has a shoulder and passes axially through the spring to compress some of the convolutions for developing a force causing the shoulder to engage with the convolutions intermediate of the ends of the spring to create a bidirectionally resilient neon tubing support.

Abstract: A conduit system for spraying cleansing and rinsing liquids on a machine for processing containers such as bottles has vertical conduit columns arranged around the machine with liquid infeed conduits confluent with the lower end of at least some of the conduit columns and opposite ends of the infeed conduits are closed by welding to a support plate that is bolted in non-interfering locations to the legs of a machine table below the level of the bottle transporting rotor. Further support for the conduit columns is obtained with pipe arms that do not conduct liquid but have opposite ends welded to the support plate and to the conduit column, respectively. Conduit struts connect between uppers ends of the conduit columns. The conduits have a series of nozzles aimed for spraying all regions of the machine that must be cleansed and sterilized intermittently or continuously.

Abstract: The invention provides an improved catheter steering mechanism for pulling a first catheter steering wire while simultaneously allowing a second catheter steering wire to remain static, and vice versa. The mechanism includes at least one rotatable gear and means, such as a rotatable knob, for manually rotating the gear. A first linearly slidable toothed rack is attached to the proximal end of one steering wire, and a second linearly slidable toothed rack is attached to the proximal end of the other steering wire. A toothed gear rotatable by rotation of the knob engages each of the toothed racks to move them linearly in opposite directions in response to rotation of said gear. Preferably three intermeshing gears are used so that movements of the racks are in the same direction as the rotation of the knob.

Abstract: Empty bottle cases that are to have filled and capped bottles inserted in them and cases filled with returned bottles are simultaneously fed to the machine on individual conveyor belts. Filled and capped bottles are fed to the machine on another individual conveyor belt and still another conveyor belt conducts the empty returned bottles away. A plurality of bottle handling heads on which there are bottle grippers are driven along a predetermined path for gripping bottles in a sequence that involves removing returned contaminated bottles from cases on one conveyor belt and transferring the bottles to another conveyor belt for discharge from the machine while at the same time, capped bottles come in on a conveyor belt and are picked up by a head and transferred to another conveyor belt where they are inserted into the empty cases that are moving on a conveyor belt.

Abstract: An ablation electrode carries a temperature sensing element for measuring the temperature of the tissue being ablated. A thermal insulating element associated with the sensing element blocks the transfer of heat energy from between the temperature sensing element and the body. The temperature sensing element therefore measures temperature without being affected by the surrounding thermal mass of the electrode.
