Abstract: A roll-carrying length of load-supporting structural material having a length substantially equivalent to the length of a heavy roll of carpet or the like to be lifted is adapted to be connected at its opposite ends to an insert tube for the roll by a pair of suspension devices, such as chains, and a pair of relatively short and rigid telescopic inserts for opposite ends, respectively, of the insert tube. Each such telescopic insert is provided with connection structure and is preferably formed therewith as a length member divided by a transverse plate member into inwardly and outwardly extending portions, and an operationally upstanding gusset plate member rigidly secured to the transverse plate member and to and along the outwardly extending portion of the length member. A second suspension device, also preferably of chain formation, is adapted to connect the roll-carrying length to an overhead crane.

Abstract: A stepladder, which may be in the form of a usual stepladder/stool combination, is provided with safety outboard frame members desirably of inverted U-shape providing upwardly arched hand holds extending upwardly beyond the upper step of the stepladder sufficiently to obstruct lateral movement beyond the ends of such upper step of the legs of a person standing on such upper step. The stepladder/stool combination in particular is preferably provided with a latching arrangement limiting movement of the safety frame members from safety positions during use of the stepladder and for not permitting the stepladder to be placed into condition for use until such safety frame members are in safety positions.

Abstract: A vane and nock assembly for use with an archery arrow shaft to make an archery arrow includes an elongate body with a plurality of vanes extending from and along the body. An arrow shaft is attached to the front of the assembly so that the vanes extend therebehind. A nock may be removably mounted to the rearward end of the assembly or may be integral with the assembly. The nock may be cooperable with a release device so the release device can hold the nock and drawing force can be applied to a bow string of an archery bow through the release device and nock held thereby to thereby draw a bow. The use of the nock and cooperating release device is not limited to use with the vane and nock assembly.

Abstract: The device and method of the invention enables a single workman to drive a tongue and groove subflooring panel into mating connection with a prelaid subfloor panel without the use of a sledgehammer. The device fits over and receives and is secured to the usual driving plank as an operative part thereof. An elongate handle extends upwardly and backwardly at an acute angle to and from its lower end portion, which is fastened to the upper face of the plank centrally and transversely thereof so the workman standing on the panel facing forwardly with his legs spread apart longitudinally therealong uses his weight to flatten the panel while he forcefully pulls the device backwardly, so the driving plank, whose rearward longitudinal edge face abuts the grooved forward edge face of the subfloor panel to be driven, drives such subfloor panel into mated connection with a rearwardly positioned, prelaid, subfloor panel.

Abstract: Apparatus for directing pressurized drying air into a hollow wall or ceiling to aid in drying a wall or ceiling which has become wet generally through a disaster such as broken pipes, flooding, leaking roof, etc., without removing a portion of the structure, but by merely removing a standard wall switch or outlet cover plate, includes a conduit having a first end sized and configured to fit over and around an electrical box as installed in a wall or ceiling and to be secured thereover. The conduit will generally be provided with holes positioned to be aligned with the usual cover plate mounting holes in a wall switch or outlet, or fixture mounting holes in the box itself, through which screws can be positioned to effect securement of the conduit.

Abstract: Adapter pipe fittings for sprinkler or drip-type irrigation systems are improved by providing a two piece pipe fitting, a manifold piece that snaps into a body piece and swivels therein. Such adapter pipe fittings are often required to be installed adjacent to a sidewalk, wall, fence, or other like obstruction whereby there is restricted clearance especially if the pipe fittings has laterally projecting offtake connector members extending therefrom. The fitting is especially well adapted for installation at sites where there is restricted clearance because the body piece can swivel about the manifold piece and the manifold piece is therefore not required to turn while the adapter pipe fitting body piece is being screwed onto an underground piping system.

Abstract: The separations resulting from capillary electrophoresis performed in a microbore capillary tube are detected on-line by focusing a light beam in the form of a line or sheet of light on the capillary passage in which the separations take place so that the width of the sheet of light encompasses the length of the passage in which separations of interest are expected to take place. The separations form concentration gradients in the capillary passage encompassed by the light beam and cause refraction of portions of the light beam. The variation in the intensity of light along the width of the light beam after passage through the sample is sensed and is indicative of the concentration gradients and separation occurring in the sample. An apparatus including a relatively short capillary tube with liquid reservoirs secured at each end may be used with the detector to perform various capillary electrophoretic separation techniques.

Abstract: A coupling for attachment to the end portion of a pipe having a circumferential shoulder in such end portion includes a coupling body which receives the end portion of the pipe therein and a set of jaw members which, after the end portion of the pipe is received in the coupling body, move to a closed position to engage the shoulder so that the coupling is locked onto the end of the pipe and the pipe cannot be pulled from the coupling because the jaw members acting against the shoulder prevent such movement. The coupling can be provided with sets of jaw members at each end to couple together two pipes with end portion shoulders or have jaw members at one end and threads, flanges, or other types of connectors at the other end. Valves or other fittings may be incorporated into the coupling between the ends of pipes being coupled.

Abstract: Methods for adjustable separation of solutes and solvents involve the combination of the use of a maximally swollen membrane and subsequent vacuum depressurization exerted on the permeate side of that membrane. By adjusting the extent of depressurization it is possible to separate solvent from solutes and solutes from each other. Improved control of separation parameters as well as improved flux rates characterize the present invention.

Abstract: A cytocentrifugation device, rotor, and apparatus are improved by providing the device with a plurality of liquid-receiving chambers arranged serially along and opening into an elongate conduit leading to and terminating within a filter-pad-holder so that a filter-pad-prewetting liquid can be passed along such conduit and into a liquid-flow opening of a filter pad held by such holder in advance of passage along said conduit and through such liquid-flow opening in the filter pad of a cell-carrying liquid sample during a centrifugation run of the apparatus. Retention of prewetting liquid in the filter pad around the sample liquid flow helps to prevent loss of cells to the filter pad. Various other structural modifications of the cytocentrifugation device and filter pads used therewith also help to prevent loss of cells to the filter pad.

Abstract: A multipurpose electric food mixing appliance specially adapted to mix and knead bread dough in combination with a blender device utilizes one power source to drive both the blender and the mixer. The appliance can sense when dough is properly kneaded and automatically shut itself off. A special dough hook/stator arrangement reduces drag on the motor and an upwardly extending cover maximizes the effective volume of the mixing receptacle. A special blender blade configuration increases the effectiveness of the blender.

Abstract: A tool for moving material includes a relatively large rectangular platform for receiving material to be moved. A handle extends from the rearward edge of the platform and is secured to the platform by a handle receiving shank secured to the platform over a portion of its length from the rearward edge of the platform. The platform is preferably a flat sheet of semi-rigid or slightly flexible material such as an aluminum-spring steel alloy and the handle receiving shank causes a slight curve in the material over the length of attachment. The platform is such that as it is pushed under material to be moved, and such material is loaded onto the platform, the platform curves or sags to receive and hold such material so that the loaded platform may be dragged and the loaded material will substantially remain on the platform during such dragging.

Abstract: An input/output interface for converting between data patterns in bit-parallel and word-serial format and data patterns in word-parallel and bit-serial format. In combination with a parallel processor, the inputting and outputting rates of the data are to be increased. To this end, a three dimensionally organized memory with a three-dimensional addressing is connected to the input and/or to the output of the parallel processor. Each address is composed of three components, of which a first component represents the significance of a bit, the second component represents the running number of the word in a limited sequence of words, and the third component represents the running number of the sequence, to which the word belongs. A switching network for the control of the memory is associated with the memory. The memory is arranged to buffer an incoming data stream of bit-parallel and word-serial format.

Abstract: A method for the treatment of the prostate gland which heats the tissues which would otherwise be surgically removed with a trans-urethral resection of the prostate. This method is accomplished by combining a radiating energy device integrated with a urinary drainage Foley type catheter, which is modified to provide cooling along the urethra surfaces. The radiating device also serves as a means to measure the tissue radiated thermal energy for the control or monitoring of temperature of the prostate tissues being heated. A urethral inserted applicator for prostate hyperthermia includes a multi-tube, balloon type catheter. The catheter includes a fluid dry tube for an energy radiator antenna applicator which also serves as a radiometric temperature sensor for measuring the temperature of the prostate tissue, and an open fluid receiving tube. An electromagnetic energy generator supplies electromagnetic energy to the applicator.

Abstract: Apparatus for projecting selected images of a scene onto a screen, such as images of a golf course looking toward a green, and for projecting and moving a spot of light on the screen superimposed on the scene, such as to represent the travel of a hit golf ball toward the green in the scene, provides both a scene projector and a light spot projector secured in fixed relationship in the same housing and provides dedicated control circuitry for controlling the apparatus in response to instruction signals received from outside the apparatus. The spot projector includes two rotatable mirrors controlled by two stepper motors to control the movement of the spot on the screen. Special circuitry is provided to generate control signal pulses for the stepper motors using a combination of a count signal pulse and a synchronizing pulse. Compensation for nonlinearities in the stepper motors may be provided by reference to a correlation table stored in memory.
