A binding for two feet in tandem on one ski that includes a boot for holding the forward foot having a detachable toe holder and a movable retainer secured to the ski between the two feet for holding the boot heel. A foot-engaging member for the rearward foot holds the retainer forward when the rearward foot is in position on the ski, and releases the retainer to free the boot should the rearward foot be removed from the ski.

A pressurized water reactor nuclear containment radiation shield which surrounds the upper portion of a pressure vessel in an ice condenser containment. The vertical walls of the neutron shield are formed in vertical sections with the lower and upper sections operable during outages, to open to promote air flow cooling along the walls in the vicinity of the vessel head.

An intravenous catheter anchoring assembly is disclosed and includes a patient-contacting membrane, a platform, and a retaining strap for securing a catheter or tubing of an administration set to a patient. The strap is attached to the platform with adjustable pull-tabs that permit a variety of catheter shapes and sizes to be secured. The strap is also elastomeric so that the strap is stretchable and thereby grabs the secured catheter. The strap and platform further define a plurality of passageways that permit the catheter to be secured in a plurality of non-aligned directions.

A catheter anchoring assembly includes a permeable adhesive strip, a platform for securing the catheter, and a flowable adhesive layer. The flowable adhesive layer adhesively secures the platform to the adhesive strip. The flowable adhesive is applied to one side of the strip with a skin-contacting adhesive on the opposite side of the strip. The flowable adhesive layer and strip are configured so that the flowable adhesive is spaced from the skin-contacting adhesive or, at the very least, is prevented from penetrating the skin-contacting adhesive. The flowable adhesive layer and strip also permit the assembly to be very flexible and, thus, comfortable for a patient to wear.

An intruder-resistant latch useful for latching an aircraft flight deck door includes a damper for reducing noise while the door is being operated. The latch also includes a driver member having coated pins that reduce noise while the latch is in operation. The latch allows a flight deck door to be operated with minimal disturbance to a flight crew at work and/or crew members who may be resting. The latch is fabricated of ballistic impact-resistant material(s).

In a belt press of the type used to dewater heavy slurries, an improved belt drive system is provided. The upper belt is driven by at least two rollers, one of which is situated in the dewatering section wherein the upper and lower belts are squeezed and traveling together. The improved drive arrangement provides a more uniformly increasing tension in the belt as it passes through the dewatering section than in such presses heretofore. Further because the lower belt is at least partially driven by its frictional engagement with the upper belt, through the sandwiched slurry, the synchronization of the belt speeds is improved. Further improved control of the belt press performance is provided by means for sensing the speeds of the belts and responsive means for regulating the belt tensioning systems accordingly.

An injection site (12) for infusion of parenteral fluids has a pressure-actuated valve (20) and a split septum unit (24), which prevent reflux of blood into the assembly (10). The septum unit (24) includes a resilient split septum body (64) precompressed so that the septum body (64) is caused to protrude proximally (78) upon insertion of a cannula (16). Consequently, upon removal of the cannula (16), there is essentially no “drumming” or creation of friction-induced negative pressures sufficient to generate blood reflux. The preloaded septum body (64) also has its proximal surface (74) essentially flush and coplanar with the adjacent proximal end (66b) of the tubular septum holder (66) to enhance the cleanliness of the unit (24).
