An electric motor having a snap-together construction without the use of separate fasteners. The construction of the motor removes additive tolerances for a more accurate assembly. The motor is capable of programming and testing after final assembly and can be non-destructively disassembled for repair or modification. The motor is constructed to inhibit the ready entry of water into the motor housing and to limit the effect of any water which manages to enter the housing.

Ablation tool for forming lesions in body tissue

The present tool (110), and associated methods provide for precisely controlled positioning of an ablative element (130), or an array of ablative elements, against a tissue targeted for treatment. Such treatment is in the form of a lesion, caused by energy emitted from the ablative element, selectively changing or destroying cells within the target tissue. The tool incorporates an element array. This element array consists of one or more energy emitting (ablative) elements. The energy delivered may be in the form of radio frequency, microwave, ultrasound, light, and cryogenics, among others. The element array may also incorporate one or more temperature sensing elements (150). Further, this element may incorporate a fluid system providing re-circulative cooling or fluid delivery to cool the element array, and/or surrounding tissue. In one use of the tool, the element array, which is located at the distal end of an elongate member, is positioned against cardiac tissue during an open heart procedure. The elongate member, the element array may be bent, formed to facilitate access and to produce the desired lesion shape.

Internal tank disengaging system

A method for separating lighter components of a hydrocarbon product in a container tank includes introducing the hydrocarbon product into the container tank via an inlet located near or at the bottom of the container tank; routing the hydrocarbon product through a pipe-in-pipe conduit that is at least partially surrounded by a bulk fluid stored in the container tank; providing a vapor-liquid interface that allows efficient evaporation of the lighter components resulting in separation of the lighter components and a processed hydrocarbon product; and routing the processed hydrocarbon product into the annular space of the pipe-in-pipe conduit thereby thermally insulating incoming hydrocarbon product from the surrounding bulk fluid and eliminating or minimizing vapor liquid equilibrium shift of the incoming hydrocarbon product caused by increased head pressure and/or reduction in temperature of the incoming hydrocarbon product.
