Abstract: An improved process and/or system for coating of a metal strip includes means for continuous travel of the strip and a chamber for substantially completely enclosing the strip beyond an area for application of a mixture of coating and solvent. In that chamber is at least one induction coil for induction heating the strip to drive off the solvent, means for introducing substantially pure nitrogen near opposite ends of the travel of the strip therein and in between the places of introduction of the substantially pure nitrogen means for removing the resultant mixture of nitrogen and solvent which mixture is then at least largely separated into its components and reclaimed nitrogen brought back into the chamber at locations between the location of removal of the mixture and the respective locations of introduction of substantially pure nitrogen. The temperature of the interior atmosphere of the chamber is automatically maintained at a predetermined temperature preferably within the range between about 300.degree.

Abstract: A positive opening device for pinch type valves having an elastomeric body consisting of a generally cylindrical sleeve portion forming a material flow passage, with flange portions at the ends for attachment into material flow lines. Under low pressure conditions of operation, or where the sleeve portion has taken a set, being deformed or in partially closed position, it is desireable to improve the function of restoring the sleeve to a full open condition, whether of a full round type or of a pre-pinched type. The sleeve consists of an elastomeric inner layer surrounded by multiple plies of fabric reinforcement, embedded in elastomeric material in the valve body finalized form, and the fabric reinforcement extends through the sleeve and into the flanged ends. End reinforcements extending partially through the sleeve and up into the flanges are added to the body structure.

Abstract: The bus bars inside the protective conduit sheathing are on a number of different levels, one for each phase. They lie flat with the wide cross-sectional dimensions horizontal and side-by-side to each other in a plurality of groups of preferably three segments each. Within each group there is preferably insulation around each of the three bus bars and each group of three has insulation around it as a group. Within the joint box, the bared ends of the bus bars stop on a line substantially short of the bared ends of the next set of bus bars and a single conductive plate of thickness the same as that of each of the bus bars, which are themselves of the same thickness to each other, spans the gap between the bus bars connecting the two sets of bus bars to each other.

Abstract: A spherical-shaped, honeycombed segment for positioning downstream of a bend or turn, in an air flow duct for rapidly returning air flow to a uniform, or predictable, cross-sectional flow.

Abstract: A composite bearingless helicopter rotor system utilizes one single and only flexible strap as at least the principal wing support, and also preferably has also a blade pitch shaft. The line of shear centers of the flexible strap, the line of shear centers of the blade pitch shaft, and the pitch axis each lie somewhere along the one straight line, or substantially so.The cross section of the flexible strap may vary but in each case it is one which is asymmetrical relative to a line through its center of gravity and parallel to the axis of rotation of a rotor, and in each case the line of shear centers of the flexible strap, the line of shear centers of the blade pitch shaft and the pitch axis all are spaced from the line of centers of gravity of the flexible strap. A number of examples of varying specific overall configurations of flex straps and blade pitch shaft will be found described and illustrated herein, of which an example is that in FIG.

Abstract: A flat, rectangular case for storing a lengthy flexible endoscopic accessory instrument when the instrument is not being used. The various instruments, which are in the form of thin flexible cables up to seven feet long, having a linear bias, are stored individually, in the case, in a coiled state. The natural bias of the instrument serves to position and secure the instrument within the case. The instruments can be readily inserted into, and withdrawn from, the case through an opening in the side wall. A plurality of cases can be supported adjacent one another in a rack.

Abstract: A modification for the M-16 U.S. Army rifle wherein the bolt mechanism is activated by mechanical means instead of the present gas means.

Abstract: To analyze golf strokes, the disclosed device has a mat assembly and a console, the mat assembly preferably including an electrically conducting base plate, mat, artificial grass, tee and eight special switches. The switches are arranged one behind and another in front of the tee, with the other six forming an oblong rectangle extending along the path of the stroke from somewhat behind to well in front of the tee, with four of them at the corners of the rectangle and the other two half way along its long sides. The analysis includes a for evaluating a golf club swing, which method compares "I" with "II", "I" being the time it takes for a swung gold club head to travel from a first pair of the six switches (actuated just prior to passing the golf ball position) to a second pair of the six switches (actuated just past the golf ball position) and "II" being the time it takes for the golf club head to travel from the second pair of switches to the third pair of the six switches.

Abstract: In a bus conduit electrical distribution system in which the conduit is normally of U cross-section with shallow U cross-sectional cover over it, the system has special joint setups in which both the conduit and the cover have double members lying one on top of the other in an overlapping manner and capable of assuming longitudinally contracted and longitudinally extended relative positions in relation to each other. The bus bars overlap at their ends and have deep slots coming in from their ends to give them a deep U shape from the longitudinal standpoint in such joint setups. In the interior of the joint setups there are disc-shaped insulating spacers with interfitting circular projections and preferably there are also additional longitudinally elongated insulating spacers. In another form of joint setup which will be used for other joints in the same system, one of the overlapping bus bars will take a hook shape.

Abstract: In the present invention the cell of the electrolytic hygrometer is fabricated with a helical pair of different wires which may be either two precious metals or one of these with one non-precious metal. Appropriate polarities are included.

Also involved here are preparations such as dry mixes, frozen concentrates and syrups.

Abstract: This involves a seating setup for people sitting side by side in a relatively cold area such as a players' bench at a football field, in which a self-contained heater is preferably located parallel to and adjacent a back wall of the setup, which back wall together with front and side walls and seat and backrest form an enclosure underneath the seat and also in back of the backrest. Heat from the heater goes into a preferably perforated pipe running the length of the enclosure underneath the seat. The front wall has openings from the outside into small individual enclosures, which openings are positioned to admit the lower legs and feet of people sitting on the seat, and are covered by interior doors when not in use; the upper part of the backrest has openings from which hot air is directed downwardly on the shoulders and surrounding areas of the bodies of people sitting on the seat; within the back part of the enclosure are areas for warming such things as footballs and towels.

Abstract: The invention relates to single, paired opposite phased and multiple stacked insulated flexible or rigid bus bar electrical conductors of copper or aluminum assembled side by side (optionally in a factory or at installation site) as high current density circuits into open trays of substantial length and covers to totally enclose a heat transfer tray co-extensive with the tray and having clamps extending across the tray to secure the cover to the tray and urging the cover upon conductors or conductor joints in the tray by tightening single bolts per clamp. The system includes also making operable end-to-end overlap compression circuit joints of bus bar conductors simultaneously with one or more single bolt clamps for each single, paired phase and multiple stack, electrically insulated apart and supported within the metal tray.
