Method and systems for volumetric tissue ablation

A volumetric tissue ablation apparatus includes a probe having a plurality of wires journaled through a catheter with a proximal end connected to the active terminal of a generator and a distal end projecting from a distal end of the catheter. The probe wire distal ends are arranged in an array with the distal ends located generally radially and uniformly spaced-apart from the catheter distal end. A conductor connected to the return terminal of the generator is located relative to the probe wire array to form a closed electrical circuit through tissue to be ablated. Preferably, the probe wire array includes 10 wires, each formed in an arch from the catheter distal end. The conductor can be either a conventional ground plate upon which the tissue is supported, or a conductor wire extending through the probe and electrically insulated from the probe wires.

Failsafe injected adhesive joint

A composite member is joined to another composite or noncomposite member, using liquid or paste adhesive resin that cures in the joint. The joint is configured in such a way that the adhesive forms an interlocking key within recesses in the joined members that prevents joint disassembly once the adhesive has cured and hardened. Both of the members are provided with recesses extending along their lengths in the joint. The recesses register with each other to define a cavity and may undulate. The recessed are designed in such a way as to take the full load capability if the joint, even if there is no adhesion to the joined members. Adhesive is injected into the cavity through injection ports spaced periodically along the length of the joint.

Clutch cooling grooves for uniform plate temperature in friction launch

Clutch cooling grooves formed on a friction plate are provided. The grooves are shaped to provide for substantially uniform steel disk temperatures in friction launch of a vehicle. The grooves are shaped such that the largest cross-sectional area is located adjacent to what would otherwise have been a hot area on the steel disk and the smallest cross-sectional area is located at the coolest location on the steel disk, at the cooling fluid inlet. Thus, the groove is shaped such that the smallest cross-sectional area is located at the cooling fluid inlet, the largest cross-sectional area is located between the cooling fluid inlet and the cooling fluid outlet, and the cooling fluid outlet has a cross-sectional area larger than the cooling fluid inlet and smaller than the cross-sectional area adjacent to the hot spot of the steel disk, between the cooling fluid inlet and the cooling fluid outlet.

Hook commutator

In a hook commutator of the prior art, a soldered connection (15), which connects a carbon segment (13) to a lamination (11) can become detached, since in the hot staking process for securing the winding wire, heat is produced. A hook commutator (1) of the invention has reduced thermal conduction in a region between the commutator hook (19) and the carbon segment (13), and thus the soldered connection (15) is protected against excessively high heat.

Freezer segment for a freezer for confectionary with segments including channels for direct evaporation of CO.sub.2

The present invention concerns a freezer segment for a freezer of the type used for casting confectionery in molds which are cooled for freezing and subsequently supplied with heat for a short period, whereafter stripping occurs. Cooling of the molds is effected by using direct evaporation of CO2. The advantage of such a freezer segment is that there is no use for both a primary and a secondary cooling circuit. Another advantage in using a system according to the invention is that working with temperatures down to about minus 50° C. is enabled, compared to about minus 40° C. with brine systems. The low freezing temperature entails that the capacity of a given system is increased by about 40%.

Connection assembly for through tubing conveyed submersible pumps

An electrical submersible pumping (ESP) system for use in a wellbore that can be assembled in the wellbore. Upper and lower pump tandems are fitted with connectors that align the tandems when coupled in the wellbore. The connectors on the lower tandems have bores with enlarged openings on upward facing surfaces. Downward pointing pins are on lower facing surfaces of the connectors on the upper tandems. The cross sectional area of each bore decreases with distance away from the openings, so that as the pins insert into the bores the pins move along a helical path that in turn rotates the upper tandem into a designated azimuth and into alignment with the lower tandem. Properly aligning the upper and lower tandems couples respective drive and driven shafts in the tandems as the upper tandem lands on the lower tandem.

Clutch mechanism

In a clutch mechanism, non-magnetic portions of an armature and non-magnetic portions of a pulley are offset from one another in a radial direction of a rotating shaft. For this reason, in an attracting magnetic circuit, magnetic flux passes between an outer cylindrical portion and an inner cylindrical portion so as to avoid the non-magnetic portions of the armature and the non-magnetic portions of the pulley. Accordingly, magnetic flux passes through a boundary between the armature and the pulley six times. The number of poles of the attracting magnetic circuit is increased. The physical size of a permanent magnet can be reduced. For this reason, the physical size of the clutch mechanism is reduced. As a result, the power consumption of an electromagnetic coil can be reduced by increasing the cross-sectional areas of coil portions. The physical size of the clutch mechanism is reduced and the power consumed is reduced.
