Abstract: Embodiments of a cot comprise a support frame, legs coupled to the support frame, at least one hydraulic actuator configured to raise or lower the legs, and a manual release system coupled to the at least one actuator and configured to lower the cot manually at a controlled descent rate. The manual release system comprises a manual actuation component, a manual release valve operable to be opened upon actuation by the manual actuation component, a fluid reservoir operable to receive hydraulic fluid from the at least one actuator upon opening of the manual valve; and a flow regulator configured to control the flow rate of the hydraulic fluid into the fluid reservoir, wherein the release of hydraulic fluid into the fluid reservoir at the controlled flow rate is configured to manually lower the cot at the controlled descent rate.

Abstract: A reamer guide system may include a reamer guide that is configured to guide a reamer to at least two bones that are to be reamed to form a countersink. The reamer guide may be configured to temporarily couple to the at least two bones that are to be reamed so as to prevent substantial separation of the at least two bones during the reaming. The reamer guide system may further include a positioning aid that is configured to receive a locating element. The locating element is configured to temporarily couple to a target location adjacent the bones that are to be reamed. The reamer is configured to receive the locating element and advance along the locating element to the target location.

Abstract: A composition that includes isocyanate group containing compounds that include on average i) a NCO functionality less than or equal to 3.5; and ii) from 1.5 to 8 percent by weight, based on the isocyanate containing compound, of allophanate groups; and which is substantially free of uretdione groups. The composition can be used in two component elastomeric coating compositions that include a component A the above-described composition and a component B that includes a compound containing one or more functional groups that are reactive with isocyanate groups. The elastomeric coating compositions can be used to coat substrates.

Abstract: The present invention is directed to a non-aqueous composition curable by UV radiation broadly comprising a mixture of two UV curable urethane acrylates. The invention is also directed to a coating process using such composition. One of the urethane acrylates is the reaction product of an isocyanate and a specific OH functional lactone ester (meth)acrylate. The other urethane acrylate is the reaction product of an isocyanate and a specific hydroxy functional (meth)acrylate.

Abstract: Solvent-based, dual cure coatings incorporating thermally curable blocked polyisocyanates, which also contain unsaturated linkages, and a method for preparing these coatings. The unsaturated linkages, such as acrylate groups, can be crosslinked by free-radical mechanisms such as UV curing.

Abstract: Radiographic films can be processed using conventional developing agents, either in the films or in solution. The films also include from about 0.02 to about 1 mg/dm.sup.2 of thialkylene bis(ammonium salt). The solution used for development is replenished at a low rate with a chemical base as the sole developer replenishing agent. The chemical base maintains developer composition pH at from about 9 to about 11 and enables processing of films without the use of conventional developer replenishing solutions or replenishment rates.

Abstract: A process for the formation of a patterned resist image upon a substrate comprises the steps of: (i) mechanically applying a layer of a suspension of a powdered solid photocurable material in a liquid carrier to the substrate; (ii) drying the resultant layer by evaporation of the liquid carrier and reflowing the powder, under the action of heat, to give a coherent film; (iii) imagewise exposing the dried film to radiation through a patterned mask whereby portions of the film exposed to radiation are cured; and (iv) subsequently developing the exposed film by removing unexposed portions thereof with an appropriate solvent.
