Abstract: A brace for external fixation of long bone fractures which includes "I"-shaped member and cross-shaped elongate members, both of which are curved along a longitudinal axis to fit around the limb and which interlap to provide circumferential support. The two-piece, curved configuration concentrates the load applied to the limb over a smaller surface area and is, therefore, more effective at immobilizing the fractured bone while allowing access to the skin for wound management, surgery, and hygiene without removing the brace. The configuration also makes possible the adjustment of the brace at three independent points to provide for improved fit over a wider variety of sizes and shapes of limbs than previously available.

Abstract: A sorting machine for separating substandard items from a continuous stream of products is disclosed wherein the ejector that removes the detected substandard items includes an ejector finger of monolithic structure and homogeneous material and an actuator. The ejector finger includes a base fixedly attached with respect to the product stream, a contactor normally withdrawn from the product stream when standard products are in the stream and for entering the product stream to eject a detected substandard item, and a hinge of reduced dimension connecting the ejector finger base to the ejector finger contactor. The hinge is biased to normally withdraw the ejector finger contactor from the product stream. The actuator flexes the ejector hinge to move the ejector contactor so that it enters the product stream for ejecting each detected substandard item. The monolithic structure and homogeneous material are resistant to wear from environmental conditions.

Abstract: A dynamic trip level setting apparatus is described for changing the comparison ratio with which products are optically sorted using first and second reflectance color values. The reflectance ratio for each image sorted is supplied to a RAM to update the RAM's memory. The dynamic values in the RAM are periodically employed to update a color sensitivity factor supplied to a battery-backed RAM. The battery-backed RAM value is employed in a logic device employing an algorithm and produces a variable output against which the ratio of "breaker" products (neither above a first color acceptance level nor below a second color reject level) is compared to produce a reject signal when the comparison results in an output indicating reject is appropriate.

Corner posts employing the same basic structure as the in-line posts or specifically designed posts are provided. The fence frame comprised of posts and railings are suitable for receiving a fence covering made up of aluminum sheet panels, plastic panels, wood pickets, plastic pickets, metal rods or other coverings of choice.

Abstract: A method of and apparatus for bagging ice cubes produced by a plurality of cubers with only one bagger when the cubers are stacked side-by-side with the ice produced by each cuber falling into one of two hoppers. The ice is moved from each hopper alternately to the bagger. There each batch of ice cubes is dropped into a bag, the bag sealed, and moved to a storage bin positioned below the bagger. The bags have a short side and a long side with the long side having holes to allow the bags to be supported by horizontal parallel rods extending through the holes. A platen is moved against the short side of a plurality of bags hanging from a first set of parallel rods extending through the holes in the long side of the bags. The air pressure between the platen and the short side of the bag is reduced to cause ambient atmospheric pressure to hold the short side of the outside bag against the platen.

Abstract: Emergency breathing equipment intended to provide short term life support by ducting breathable gas from a small capacity source to a user via a restricted flow path that allows only limited flow rates so as to prevent hyperventilation and wastage of breathable gas is characterised by a demand valve having the poppet controlled by a demand pressure-sensing diaphragm to control an inhalation flow path, the diaphragm also controlling an exhalation flow path so as to switch the user between said flow paths by opening one and closing the other, as it moves between two positions under the influence of demand pressure. The equipment is also characterised by a reactive pressure regulator for the breathable gas and having its delivery pressure switchable by a trigger element that in an installed position unloads the reaction member so as to provide zero delivery pressure, withdrawal of the trigger element allowing the reaction load to operate to set a fixed positive delivery pressure.
