Abstract: The present invention is directed to a unique thermal insulation panel. More specifically, the present invention is directed to a vacuum insulated panel formed of a highly impermeable evacuated envelope that is supported by a thermal barrier made of a macro-structural support structure having a cell or void size of 0.5 micron or greater. Preferably, the panel includes a getter material. Further, the present invention is directed to a thermal insulation barrier of a macro-structural structure. Preferably, the barrier is formed of elements having a geometric shape of a repetitive three dimensional design that permits stacking of one thermal insulation element with another thermal insulation element having a complimentary geometric shape, and which locks movement of adjacent thermal insulation elements in at least one of the directions 90.degree. to the stacking direction.

The present invention is further directed to a "getter" material supporting structure which comprises an air lock chamber with an opening which when open permits the gases surrounding the barrier in the envelope after evacuation access to the "getter" material.

Abstract: The present invention is directed to thermal insulation elements each formed of a structural material with a highly emittant surface having a geometric shape of a repetitive three dimensional design which permits alternate stacking of one thermal insulation element alternately with another thermal insulation element and which locks movement of adjacent thermal insulation elements in at least one of the directions 90.degree. to the stacking direction; and more specifically, to a thermal insulation barrier having at least three alternately stacked thermal insulation elements, two of the thermal insulation elements having the same design, the alternate thermal insulation element having a complementary design, whereby when the thermal insulation elements are alternately stacked, any point of contact between thermal insulation elements is a contact between the alternate thermal insulation element and only one of the other thermal insulation elements.

Abstract: The present invention is directed to a surgical rongeur having a body, a replaceable hollow cutting member and an actuator for moving the cutting member. The body has a distal end and a proximal end. The body at the distal end has an extended member terminating in an anvil. Between the distal end and the proximal end is a hollow portion, and at the proximal end of the body is a handle which actuates the cutting member. The replaceable hollow cutting member is movable within and guided by said hollow portion of the body but extends beyond the body at the proximal end. The hollow cutting member is actuated to cut any bodily material positioned between the anvil of the body and the cutting member, capturing the cut material in the hollow cutting member.

Abstract: In a cased wellbore having one or more cased and cemented drainholes extending therefrom such that the elliptical shaped opening or junction of each drainhole with the primary well is sealed and cut flush with the inside of the primary well casing, an inventive method is disclosed for: (a) isolating each perforated and/or drainhole completion within the primary wellbore, (b) providing flow control means for each completion to permit selective testing, stimulation, production, or abandonment, and (c) facilitating selective re-entry into any cased drainhole for conducting additional drilling, completion, or remedial work. In a preferred embodiment, a production liner is permanently attached within the primary well casing such that packers straddle permanent flow control devices and precut liner windows which are positioned adjacent to perforated completions and drainhole entrance openings, respectively.
