Abstract: The present invention describes a workholding apparatus for holding workpieces that are to undergo various machining processes. The workholder apparatus is particularly suitable for numerically controlled machining applications. The workholder consists of a main body having a generally flat work surface and two or more clamping assemblies slidably located beneath the work surface. The invention includes a means for accurately and repeatably clamping a workpiece to the work surface, so that a part may be removed at an intermediate stage for examination or other processing, and returned to the workholder in the same location. A major advantage of the present invention is the clamping is accomplished without producing undesirable stresses in the workpiece, and all sides of the workpiece can be exposed for machining without changing the attachment of the workpiece in the workholder. A modular and extensible embodiment of the invention is also described.

Abstract: A stack of plastic T-shirt type bags for use with a dispenser. Each bag in the stack has a pair of handles with aligned apertures for receiving the prongs of the dispenser. The stacks are retained in alignment by a releasable flap on the periphery of the aperture in each aperture integral with the bag. The stack provides for the releasable securement of adjacent flaps together for retention of bags in overlying aligned relation in the stack. Each bag has at least one discrete region of weakness between each aperture and the inward side of the respective handle stack which can be broken for detachment of a bag from the dispenser. The stack is adapted to dispensers with prongs carrying surface projections (i.e. transverse ridges) to restrict unwanted sliding of the stack along the prongs.

Abstract: Method and apparatus for fish migration past dams and other water barriers. A preferred embodiment 100 comprises a conduit 101 passing from downstream side 22 of water barrier 10 to upstream side 21 of the barrier, flow-controlling valves 102 and 105 disposed in series within conduit 101, and actuators 103 for opening valves 102 and 105 in the presence of fish. Fish 30 are attracted by flow 130 passing through conduit 101 at controlled rates by means of flow-through devices in valves 102 and 105. On entering forechamber 104 and swimming upstream the fish pass actuators 103, which cause first valve 102 to open. As first valve 102 opens, water flow through conduit 101 remains controlled and substantially uniformly turbulent under action of second valve 105. With valve 102 open fish 30 may swim to mid-span section 140 of the conduit. When no further fish are present in forechamber 104 or passing actuators 103, or enough fish are present in section 140, the first valve closes.

Abstract: A dried fruit or vegetable has a water content in the range 4% to 7%, and has a water activity of 0.4. Substantially all of the cells of the dried product are undamaged. An air drying process is gentle and contains four phases, during which the temperature of the drying air is maintained at 60° C. In a first phase the relative humidity of the drying air is allowed to rise to between 50% and 55%, and is maintained substantially constant at this value during a second phase by maintaining exchange of the drying air with fresh air substantially constant. In a third phase of the process, the relative humidity of the drying medium is permitted to decrease relatively rapidly until the fourth phase commences, at which stage the relative humidity is permitted to asymptotically approach a predetermined relative humidity value.

Abstract: The present invention describes an improved mounting device or catch intended for mounting mirrors, glass plates or other generally flat objects to walls, doors, cabinets or other appropriate surfaces. The present invention comprises a plastic shell element, similar in appearance to existing mounting devices, but having a recessed means on its back side to accommodate a support plate. The support plate is a preferably metal, generally J-shaped plate that slidably engages the plastic shell to provide much greater structural integrity to the mounting device. In addition to strengthening the basic support structure, the metal plate provides a secondary support means that can retain the supported object even in the event of a failure of the plastic shell, potentially preventing the destruction of the supported object. The improved structural features are accomplished while retaining the aesthetic features and resilient support features of prior-art plastic mounting devices.

Abstract: A high performance boat hull structure is provided which combines a V-hull bottom portion 12 with mid hull sponsons 31 and 33 which form longitudinal tunnels with adjacent structures. The mid hull sponsons 31 and 33 have horizontally disposed running surfaces to provide lift at high speeds. Outer sponsons 14 and 16 incorporate running surfaces 24 and 26 and together with mid hull sponsons 31 and 33 form a second air tunnel and engage and deflect side directed spray and wake downwardly providing additional lift and decreasing or eliminating spray and signature wake. Entrance of injected or inducted air into the air tunnel area decreases frictional engagement of the hull with water to improve efficiency and ride.

Abstract: Improvements in metallurgical conversion in accordance with the present intion consist in the preparation of a semifinished item (a charge stock) in the form of a pig by forming thereof in a molding box of a casting machine from a solid filler, for the most part an oxidizing agent, and a liquid pig iron followed by cooling, provided said solid filler and said liquid pig iron undergo, in the process of forming, an action which prevents the floating up of the solid filler in the liquid pig iron. Such an action is effected both by applying a mechanical force, in particular by providing a casting machine with a cantilever (8) having a hollow roller (9) which rests on a molding box (2) and a weighting material (10), and by choosing relative dimensions of the solid filler pieces and selecting a rate of pig casting. Optimal conditions for using such semifinished item for metallurgical conversion which in accordance with the present invention is carried out in oxygen converters and arc furnaces are described.
