Abstract: The invention provides a multilayer sleeve liner for application to the skin of a limb before applying a cast or brace. The liner is readily conformable to the limb configuration. It has a first layer that is applied to the skin. This has protective and cushioning functions. A second layer has a mesh structure that encircles the limb. It is constructed so that when its first end is pulled away from its second end, the encirclement of the limb is tightened. When one end of the mesh is attached to one end of the cast, and the other end is attached to another end of the cast, tension on the limb will tighten the liner. Without removing the cast, the liner may be adjusted by releasing one end of the mesh from the cast, and increasing or decreasing tension as necessary, then reattaching the mesh to the cast. A third layer may be provided to prevent adhesion of the cast to the liner.
Abstract: Kitchen tongs have two arms, each having a hinge end with a handle portion and a grasping end. A spring at pivotally joined hinge ends biases the grasping ends away from each other in open position. A support member on each arm intermediate the handle portion and the grasping end is located such that the weight between the hinge end and the support member is greater than the weight between the grasping end and the support member. The support members extend from the arms sufficiently to cause the grasping ends to be elevated above a horizontal planar support surface when the hinge ends and the support members are resting on the support surface so that the tongs may rest upon a planar support surface without contaminating the support surface or the grasping ends. A sliding element moves between two magnets for locking and unlocking tongs with one hand.
Abstract: A reinforced concrete wall system assembles rigid panels into two form walls in spaced apart relationship to securely hold poured concrete and reinforcing materials there between. The panels may include insulating foam. The panels are held securely side by side within a form wall by elongate connectors that have paired channels into which edges of the panels snugly fit. Each connector has brackets extending into the concrete space. Brackets are provided with perforations to receive tie rods. Each tie rod ties a bracket from one form wall to a bracket extending from the other form wall. This holds the space being filled with concrete together. The perforations are formed to resist releasing the tie rod once it has been inserted. Reinforcing steel is positioned by fastening to the tie rods.
Abstract: A floor tile has a rectangular, wear resistant, decorated upper portion. A rectangular lower portion is affixed to the upper portion by pressure sensitive adhesive on the underside of the upper portion. The lower portion has laterally projecting tongues extending outwardly from two adjacent sides. The other two adjacent sides have inwardly directed pockets. The pockets are adapted to receive the tongues of adjacent tiles to form a continuous upper portion floor covering with minimal spacing between tiles. Certain edges of the tongues and pockets are close fitting to ensure correct positioning of adjacent upper portions. The pressure sensitive adhesive above each pocket is adapted to bond with a tongue when the tiles are connected after positioning by the tongues and pockets.
Abstract: Apparatus includes at least one of inflatable blood pressure cuffs for encircling a proximal, a distal, and an intermediate portion of a limb. Electrical signals from a pressure transducer on the cuff and from skin contact electrodes on the cuff are generated during pulses from the heart or from externally generated cuff pulses. A signal processing mechanism generates numerical values that are relevant to conditions that may contribute to cardiac malfunction.
Abstract: The apparatus holds open the mouth of a plastic film bag, while holding it upright for filling. It is readily applied and removed after the filling has been done. It is easily cleaned. The holder has a convenient footprint for storage beneath the bag package when in a storage mode. The holder has arms that engage a surface of the bag proximate the bag opening and leg members that engage the other surface of the bag. The arms are removably attached to the leg members with the bag film sandwiched in between them by magnetic force. The combination of spaced-apart arms and spaced-apart leg members together hold the bag open and upright for filling.
Abstract: An apparatus and method for measuring the blood glucose level of a diabetic using insulin is noninvasive. The apparatus includes two plethysmographs that sense the blood in two fingers simultaneously. The electrodes in the plethysmographs are immersed in conductive liquids. One liquid has electric conductivity equal to blood. The other liquid is more conductive than blood. Signals from the fingers are compared to signals obtained earlier when glucose levels were known from conventional measurements. An alternative embodiment employs a single plethysmograph with one set of electrodes in a surrounding chamber and a second set of electrodes against the skin surface.
Abstract: Jaw plates for removably attaching to the jaws of machine vises extend above the top of the jaw to hold taller workpieces. They are made from aluminum alloy for readily machining to conform to contours of a workpiece not easily held by flat jaw faces. They are sections cut from a special extrusion for enhanced physical properties and economy of production. Through holes are drilled for fastening to the jaw face. The plate has a planar vertical face for lying flat on the vertical jaw face. A second face engages the top horizontal face of the jaw. A groove between the two plate faces ensures the second face engages the horizontal face of the jaw away from the intersection of the faces. Alternatively, material on the plate may conform to the workpiece when hot and retain shape when cool.
Abstract: An assembly mounts between the drain pan that collects condensate water from an air conditioner and the drain line. It includes a housing with a first end connected to the pan. A second end connects to the drain line. A shut off valve shuts off the passage to the pan while maintenance is performed. A connector is mounted on the housing between the valve and the second end. It is a female member of a water hose coupling. A male member of the coupling may be screwed in to seal it in place. Male members may have different terminations at a second end, including a barbed tube for resilient tubing, a compressed air tire valve for delivering gas, a compressed nitrogen coupling, a tapered funnel for the nozzle of vacuum/blower, and a water sensor.
Abstract: A portable wine box bar has an insulated chamber with an open top, an insulated cover for the open top, and a horizontal shoulder on the inside wall near the top. A rigid panel fits on the shoulder. A support affixed to the panel supports bag-in box containers of wine with outlets supported above the panel high enough to allow containers to be supported on the panel while filling from the outlet. Perforations in the panel and a drip tray below the tap outlet capture spills. A panel aperture permits access to items such as soft drinks stored in the chamber. When not in use, the panel may be inverted and returned to the shoulder. With the cover in place it is insulated, secure, and transportable.
Abstract: A serving receptacle dispenses food therefrom onto a diner's plate while overcoming the problem of food being dropped onto the table during dispensing. At least one dispensing ramp is coextensive with the serving dish upper surface and extends upward and horizontally over the edge of a diner's plate. Each ramp has two opposed side edges that extend upwardly from the ramp surface to reduce the chances of food or fluid dropping off the ramp during dispensing. The food is moved onto the ramp and then past the leading edge of the ramp, where it will then fall onto the diner's plate. There may be two opposed ramps that also serve as handles. The ramps have an upper surface that is slightly sloped upwardly as it approaches the outer edge of the ramp. This enables liquids to flow back into the dish instead of dripping over the edge. A drip projection under the free edge of the ramp causes liquid at the edge to drip down onto the plate.
Abstract: A telephone system includes a user-carried emergency communication system in combination with a cellular telephone. The user-carried handset has a large button on a first face. Pressing the button summons help by automatic connection to the 911 emergency telephone network. It also activates a signaling device mounted on the inside glass surface of a window that illuminates a message that 911 has been called. It may also sound an alarm. A pre-recorded massage may also be sent to the emergency call center. The other face has the functions of a cellular telephone. All elements are within the building, with installation by simply plugging cords into power outlets the same as any cellular phone and mounting the signaling device with suction cups. There are no monthly fees except for the usual cellular phone fee.
Abstract: A hydraulic boat lift assembly will raise and lower a boat cradle remotely, and will securely lock the cradle in an uppermost storage position. The lift as provided with a manual mechanism for unlocking the cradle from its uppermost storage position for operation when the hydraulic system is not available. The lift has a support frame that is mountable on the outside of the transom of a boat with hydraulic connections to a hydraulic system and controls within the boat. A lift mechanism connected to the support frame raises and lowers a cradle that supports a small boat or tender. The lift mechanism includes one or more hydraulic lift cylinders. In a retracted position of the lift cylinder, the cradle is elevated above the water in a storage position when the boat is under way. To ensure security of the tender, the lift mechanism employs a lock cylinder that prevents inadvertent motion of the lift cylinder from the retracted position by mechanical and hydraulic mechanisms.
Abstract: A portable insulated cooler has a bottom space adapted to hold ice cubes. A removable perforated panel suspended over the bottom space separates the bottom space from a central cooled storage area. A removable frame suspended above the central cooled areas holds ice cube containing flasks. Each flask has a large closable opening in its upper broad flat face to easily receive ice cubes. The lower broad face of the flask forms a cooling upper margin of the central cooled area so that the contents of the area are cooled from both top and bottom. The flasks have a flange around the upper face to rest upon the frame, while most of the flask is below the frame. This enables the insulated cooler top to close. By cooling from both top and bottom, the central area is more uniformly cooled. Opening the cooler top to access the central area creates less heat gain than with prior art devices.
Abstract: A portable draft bar has an insulated chamber with an open top, an insulated cover for the open top, and a horizontal shoulder on the inside wall near the top. A rigid panel fits on the shoulder. At least one beverage tap mounted on the panel extends above the open top, with a drip tray below the tap outlet. A cooling coil within the chamber connects the tap inlet to a pressurized beverage container, with chamber ice cooling the coil. When not in use, the panel may be inverted and returned to the shoulder. With the cover in place and the container disconnected, the device is secure and transportable.
Abstract: A wheeled article carrier is operational in either one of two conditions. A frame with a horizontal base is supported by three or four wheels with a vertical member upstanding from the base. A receptacle may be attached to the frame. A telescoping handle extends above the frame. The frame may be pulled by the handle to roll on two of the wheels. A foot board is retracted to lie securely along the vertical member. In the second condition, the carrier becomes a scooter, with the foot board extending horizontally from the base, with two of the wheels supporting the distal end of the board and the proximal end of the board fixed to the base and supported by the one or two other wheels attached to the base. A steering mechanism connects the one or two wheels on the base to the handle so that the rider may steer the scooter.
Abstract: Apparatus is simply hung on a deadbolt knob when the deadbolt is in locked position. It prevents the deadbolt knob from rotating enough to retract the deadbolt. This ensures that the door cannot be unlocked from the outside. A passage in an upper end of the apparatus is dimensioned to receive the deadbolt knob. The deadbolt knob is not round. The passage has side walls narrow enough to prevent the deadbolt knob from rotating freely within the passage. As the knob is rotated, the knob engages the side walls of the passage so that the entire apparatus rotates until the lower end of the apparatus engages the door frame. Many passages are provided so that the apparatus may be used with deadbolt knobs that have different locked positions.
Abstract: Apparatus applies chemicals to water in an air conditioning condensate tray. It has an elongate reservoir body with an open upper end, a closed lower end, and a central cavity enclosed by an encircling wall. The central cavity receives chemicals to prevent the growth of microorganisms. A closure closes the central cavity. A tubular member is operatively connected at a first end to an aperture in the wall, and has a second end extending outwardly therefrom. The second end is constructed for receiving condensate water from the condensate tray, providing a fluid passage to the central cavity in a first mode of operation when water in the condensate tray is above a preset level; and for dispensing water to the tray from the central cavity in a second mode of operation with chemicals disposed in the water from contact within the central cavity.

The central cavity receives chemicals to prevent the growth of microorganisms. A first tubular member is operatively connected at a first end to an aperture in the wall, and a second end extending outwardly for receiving condensate water from the condensate tray. A second tubular member is operatively connected to a second aperture in the wall opposite the first aperture aligned with the first member so that a cleaning brush may be passed through both members and into the condensate tray. Below the two tubular members a fluid outlet is provided with a connector for joining to a drainage system for draining the chemically treated condensate water from the cavity.
Abstract: The invention is a pot holder that will insulate the hand from heat, have adequate friction for holding, and be readily available and usable with one hand. The holder or handgrip of the invention comprises an elastomer sheet such as silicone rubber with a small permanent magnet affixed adjacent one edge. The magnet has sufficient attractive force to support the holder in place against a ferromagnetic surface such as the vertical side of a refrigerator or microwave oven, for example. In an alternative embodiment of the invention, a small piece of ferromagnetic material may be affixed to an opposite edge of the sheet to removably attach to the magnet on the opposite edge to thereby form the sheet into a tube that may be used to removably attach to a handle. The sheet may have one or both broad surfaces provided with a texture to enhance friction to provide a non-slip surface. The sheet has sufficient insulating properties to protect a hand from a hot handle.
