Abstract: A two-piece vaginal speculum has upper and lower blade members pivotally connected to each other by a slot and pin arrangement for relative pivotal and spatial adjustment of the blade members. Slots are formed in the sides of the upper blade member, and trunnions with lugs directed outwardly through the slots are formed on the sides of the lower blade member. Cheek plates in the upper blade member sides have ribs formed therein for selective engagement with teeth formed on cheek plates of the lower blade member sides. The ribs extend in the direction generally parallel to the slots, and achieve sliding engagement with the teeth so that the position of the trunnion lugs can be moved from one to another set of notches formed on the slots. The teeth and rib have engaging surfaces which are back angled at about seven degrees so that compressive forces of the patient's vaginal wall on the blades will urge the rib and the engaging tooth, and their supporting cheek plates, into engagement.

Abstract: A variable attenuation support system for a payload. A base support and a payload support are separated. A plurality of mounting pads are affixed to the base support, one such pad substantially at each corner of a first imaginary shaped plane. A plurality of mounting pads are affixed to the payload support, one such pad substantially at each corner of a second imaginary shaped plane which is similar in shape to, but larger than, and parallel to, the first plane. The planes are spaced apart and are relatively centered with corresponding sides parallel. A pair of pads are formed at each of the corresponding corners of the planes. An adjustable shock mount is provided for each of the pairs of pads. Each adjustable shock mount comprises a plurality of separable resilient shock absorbers, means for connecting a first one of the shock absorbers between the corresponding pair of pads, and means for releasably locking at least a second one of the shock absorbers in between the corresponding pair of pads.

Abstract: The shelter is constructed of composite, multilayer panels comprising an exterior skin aluminum sheet layer, a polymer composition foam layer, a divider skin aluminum sheet layer, an aluminum honeycomb layer, and an interior skin aluminum sheet layer. The five layers are bonded together to form the panel. In accordance with one aspect of the invention, the polymer composition foam layer has a scored surface to increase adhesive area and to increase the length of the shear failure line. In another aspect of the invention, the panels are closed out at at least two edges thereof with an extruded polymer-fiberglass closeout bar which is positioned between the inner and outer panel skins at the edge thereof and bonded thereto. These closeout bars are configured for rigid attachment between adjacent panels.
