Abstract: A keyboard for use with a computer. The keyboard has an alphanumeric keypad with alphanumeric keys, a calculator keypad with calculator keys including numeric and arithmetic keys which also function as the standard number pad on a calculator, a keypad matrix, a processor and a bi-directional communications interface. The processor, through the keypad matrix, receives signals indicating actuation of the keys, resolves keystrokes corresponding to the actuated keys, and sends the keystrokes to the computer through the communications interface. The keyboard has a tape mode, a calculator mode and a keyboard mode. The processor, keyboard matrix and calculator keypad act as a discrete calculator when in calculator mode. There is a send key for sending a number active in the calculator to the computer as a series of keystrokes for display on the monitor. In tape mode, the processor sends keystrokes to the computer corresponding to intermediate steps in calculations entered at the calculator keypad.

A rod is pivotally mounted to ends of the support brackets, and a plurality of rollers are rotatably mounted on the rod. A container lid is provided which includes a plurality of runners which engage the plurality of rollers. The support brackets pivot from a closed position to an open position wherein the container lid is slightly raised from the container opening. While in the open position, the container lid is rolled on the rollers away from the container opening to provide access to the container.

Abstract: A sump shield assembly particularly adapted for creating a watertight seal with a container sump which are used with underground fluid storage tanks is disclosed. The assembly prevents water from entering a containment sump. This assembly includes a sump adapter, a sump shield and spill collector boots which couple to spill collectors that are commonly used to collect fluid spilled during the filling or evacuation of underground fluid storage tanks. The sump adapter is mounted to a containment sump, and includes a groove to receive a sealing member. The sump shield is shaped and configured to mate with the sump adapter and the gasket, and is secured to the sump adapter with releasable latches. The latches are used to make the shield easily removable, and also provide the clamping force needed to compress the gasket sufficiently to create a watertight seal. The spill collector boots join the spill collectors and the sump shield, and have watertight seals at both ends.

Abstract: A trailer hitch assembly having a connecting arm disposed within a sleeve and pivotally coupled within the sleeve by a bolt. A tongue at the distal end of the arm rests on one or more air cushions which provide damping or shock absorption to the coupled arm and sleeve during travel. The air cushions are mounted between the tongue and a cross brace of a trailer frame assembly. A hitch coupling is included at a distal end of the arm for engaging a hitch on a towing vehicle. Inflation or deflation of the air cushions allows adjustment of the amount of shock absorption according to the trailer load or road surface conditions.

Abstract: A method and apparatus for recovering metallic aluminum from furnace dross. The method includes reducing the particle size of the dross and passing the resulting dross particles over the surface of an inclined linear induction motor to separate the more conductive, aluminum-metal-containing particles from the less or non-conductive particles that contain little or no metallic aluminum. The linear induction motor provides an electromagnetic field that operates to levitate the conductive, aluminum-containing particles, while those particles that include little or no aluminum are not affected by the electromagnetic field. A flow splitter positioned at the lower end of the motor separates the conductive particles from the substantially non-conductive particles. Metallic aluminum recovery rates of about 55% and higher of the aluminum contained in the furnace dross have been achieved. The resulting product has been enriched by a factor of twelve times over that of the infeed material.

Abstract: A sump cover containment assembly is provided for use with containment sumps utilized with underground fluid holding tanks having a sump cover with an access hole therein, a frame which communicates with the containment sump to which the sump cover is attached and a sump shield positioned between the containment sump and the frame and having a hole which communicates with the interior of the containment sump as well as with the sump cover access hole.

Abstract: A receptacle for accumulating spilled liquids about the inlet pipe of a storage tank is slidably fitted within a stationary housing. The receptacle includes an outlet spout connected to the inlet pipe. A center pipe fits within the spout for connection to a supply line. Liquid flows from the supply line through the center pipe into the tank inlet pipe. Spillage is collected in the receptacle and, if desired, permitted to flow into the tank via valved passages in the receptacle bottom.

Abstract: An adapter for connecting in fluid communication a liquid dispensing syringe with the interior of a bottle containing a liquid, such as a liquid medication, includes a tubular body member composed of resilient material and being generally cylindrical in shape to fit snugly within the mouth of the bottle. Projections or beads are provided on the body member for engaging the inside surface of the bottle thereof in a continuous line of engagement therewith with a high pressure per unit area of engagement. An opening extends axially through the body member for receiving the nozzle of the syringe, and the opening includes a forward nozzle receiving portion and a rear portion. The axial length of the forward portion is substantially the same as the axial length of the nozzle so that the exit end of the nozzle terminates at the rear enlarged portion when the nozzle is inserted fully within the opening.

Abstract: An adapter for the mouth of a container, such as a bottle of liquid medication, includes a body member adapted to fit sealingly into the mouth of the container, body member having a central aperture for receiving the nozzle of a syringe-type medication dispenser. In one embodiment of the invention, the body member includes a vent hole and a downwardly depending tube adapted to extend into the container to enable liquids to be drawn from deep containers without inverting them. A valve device retains the liquid in the tube near the body member. The valve is in the form of a flexible web extending transversely across the central aperture, the web having a slit or opening therein for receiving the nozzle of the dispenser to enable it to extend axially therethrough to gain access to the liquid medication disposed within the container.

Abstract: A smoker's appliance capable of producing aircooled smoke in a sanitary and ashless manner for the pleasure of the user. The appliance is generally shaped like a gun having a cylindrical body with a threaded head at one end. A tube extends through an aperture formed in a cap which is threadedly engageable with the head. With the cap tightened onto the body, the tube permits communication between the chamber and the surrounding air. A flexible bulb is attached to the body at a location near an end opposite the head. By the use of appropriate check valves, the bulb, when squeezed, forces air into the chamber within the body without permitting its escape. When a lighted cigarette is inserted into a free end of the tube within the chamber, operation of the bulb causes a unitary direction of air flow through the appliance which assures long life for the cigarette. Cigarette smoke thus passes through the cigarette itself and exits from the tube, being preferably directed into the mouth of the user.
