Abstract: A mitering apparatus for frames or moldings includes a base plate on which mitering saw guides and a pair of work holding vises or clamps are mounted. Each clamp has a fixed and a movable jaw and the two clamps are mountable on the base plate for either a standard 45.degree. cut or for a 30.degree. or 22-1/2.degree. cut in some instances. Guideways for the two clamps or vises are provided on the base plate for coaction with a pivoted clamp adjusting lever and links which interconnect the lever with the clamps so that they may be adjusted bodily in unison and oppositely along linear paths to assure perfect alignment of the mitered ends of molding sections or other work prior to joining by means of nails or glue. Realignment of the joint is also possible if slippage of parts should occur during nailing. It is unnecessary to unclamp the work sections or loosen the movable clamp jaws to effect proper alignment or realignment of the work.

Abstract: An adjustable flange for a dry lube variable speed sheave assembly having an unmachined bore is centered on a vacuum fixture. A thin dry bearing material is secured and located axially and radially within the flange bore and the annular space between the thin dry bearing material and the flange bore is filled with a high compressive modulus material such as epoxy. The dry bearing material is maintained flat during the process by the application of vacuum through the fixture. After curing, the completed adjustable flange is removed for the fixture and assembled with the sleeve component of a sheave. In accordance with a variation of the method, the separately formed thin dry bearing material is eliminated and a suitable dry lube material is mixed with the epoxy-like cement prior to injecting the same into said annular space. Following curing, this material becomes the dry lube bearing of the flange.

Abstract: Foam glass developed under vacuum is continuously formed into a slab while being cladded on its major sides and longitudinal edges with sheet metal. The metal claddings or facings for the two major sides of the slab are held under tension during the solidifying of the slab body. End plates are inserted transversely through the product at specified points during its movement and sections of the continuous product are cut to length, whereby the sections are prestressed partly as a result of compression along two axes caused by differing coefficients of expansion of the cladding and foam glass body and partly to atmospheric compression of the product on a third axis perpendicular to its major sides. Modified forms of the product eliminate the metal cladding or skin entirely or provide the same as a cast-on coating without mechanical prestressing.

Abstract: A floating cylinder or roller attachment for mobile pick-up balers is positioned slightly ahead of the rotating pick-up teeth and is held somewhat above the ground while being freely rotatable on a cross shaft. The cross shaft is held on a pair of support arms which may swing vertically and whose rear ends are pivoted to the top of the auger hood. Intermediate support for the pivoted cylinder support arms is afforded by an existing transverse bar on the baler. The attachment prevents hay or other crops in a windrow from being rolled or kicked forwardly by the baler pick-up mechanism and thus prevents loss of hay while promoting an even flow into the feed auger of the baler.

Abstract: A storage battery terminal post receives a split connector cap formed of compatible metal. A rear extension of the cap is secured by a clamping set screw to an exposed end of a battery cable. A screw-threaded pressure sleeve is received by internal threads of a housing and has its forward end bearing on a full circle flange portion of the connector cap. The force exerted by the pressure sleeve on such flange produces closing of the split connector cap around the battery terminal post by a camming action of curved connector cap sections with a coacting curved wall of the housing.

Abstract: In accordance with one embodiment of the invention, a total cardiac replacement device or four chambered heart for orthotopic placement is provided. This device is a pulsatile flow, synchronous ventricular ejection pump which closely simulates the action of the human heart. An internal electrical drive motor is powered by radio frequency induction across intact skin without external connections. A grooved rotary shaft driven by the motor powers a linear follower disc in one direction to compress two blood compatible sacs which simulate the left ventricle and right ventricle of the heart by pumping blood through the aorta and pulmonary artery, respectively. Return movement of the follower disc in terms of rate is a function of right atrial and left atrial pressure and volume. Stroke volume of each simulated ventricle is independent of the other, as in the natural heart.

Abstract: A simplified and versatile carpet roll-up mechanism allows customer carpet orders to be rolled pile in or pile out after cutting to proper length in a combination machine for unrolling carpet from a supply roll, measuring and cutting transversely of the web. The improved roll-up mechanism allows four cooperating rolls to manipulate the carpet web without employing coacting mechanical bars or fingers customarily required to initiate the rolling operation. Following completion of the roll, the roll is cleanly ejected from the roll-up mechanism. The mechanism is under control of a uniquely arranged system of power cylinders.

Abstract: A weedless fish hook employs a spring guard having angled contact areas which, when pulled against the interior of the mouth of the fish at the strike, will cause the guard to open with a camming action and expose the fish hook barb for penetration. The guard may have a much stronger tension than was heretofore possible with weedless hooks and there is no necessity for attaching a portion of the line to the guard to assure proper depression or opening of the guard at the moment of the strike.

Abstract: Essentially L-shaped housing modules used to construct a multi-level apartment building are transported to an erection site on a flat bed trailer drawn by a winch-equipped towing truck. An identical truck is used to tow a construction crane tower to the site on a trailer vehicle which is later utilized as a counterweight for a simplified fixed radius non-rotating crane based on one of the trucks and erected by use of the second truck. Twin opposing cranes are employed to lift and manipulate housing modules at the site. A special lifting truss with hinged transverse extensions is employed in conjunction with the twin cranes and has means for coupling to each housing module so as to add to the rigidity of the latter. Worker platforms on the crane towers have manual winch means for making fine adjustments in the attitude of each module so that the module can be correctly set into place on underlying modules or on a prepared foundation.
