Abstract: An aerator particularly useful in the aeration of waste treatment systems. The aerator has a hollow support pipe communicating air to arms having diffuser stones, the support pipe extending upwardly from a weighted base. The diffuser stones are near the ends of the arms. A first pair of arms is lower than a second pair of arms and each pair of arms has a common axis. The axes of the arms are angled relative to each other. The diffusers on the lower pair of arms are angled upward and the diffusers on the upper arms are angled downward. The aerator provides a large projected area for the diffusers as viewed from above, and spreads air bubbles laterally away from the aerator. The aerator of the present invention keeps the diffusers above the bottom at an optimized height while maximizing aeration.

Abstract: A double hose having a hose contained within a hose. First and second hose assemblies to be joined together so each have an outer hose and an inner hose. Ends coupler parts of the inner hoses are maintained in a concentric relationship within coupler parts on the ends of the outer hoses. The coupler parts are joinable to each other. One of the ends of the inner hoses extends beyond its corresponding coupler part to form a male and is received in the end of the other inner hose within the other coupler part. As such, when the flanges on the outer coupler parts of the outer hoses are joined together the inner hoses are joined to form a fluid tight seal.

Abstract: A suspension for a trailer vehicle that allows the trailer itself to be used as a ramp. The suspension has an axle having an axis and wheels at each end of the axle. The axle is pivotally connected to the vehicle at a pivotal connection and the axis of the axle is offset from the pivotal connection to the vehicle. An actuation device having a first and second end is pivotally connected to the axle at its first end. The actuation device is movable between a retracted length and extended length. Shifting the actuation device between its retracted and extended lengths causes the axle to pivot about the pivotal connection on the trailer, thereby changing the height of the vehicle relative to the ground surface. The trailer can be used as a ramp, thus, eliminating the need for separate ramps.

The trailer may contain multiple floors defining separate living areas. The trailer may also have expandable rooms in the lower body portion which are slidingly retained within the lower body portion and provide additional room within the lower body portion.

Abstract: A method for producing insulation tape. A strip of fabric is provided and a layer of insulation powder material is deposited onto the fabric. The fabric is folded over the insulation powder to form insulation tape that may be wrapped around pipes. The method of folding the fabric includes first bending the fabric into a trough shape that has a bottom portion and lateral upstanding flaps that terminate in lateral edges. The insulation powder may be deposited onto the bottom portion of the trough. The insulation powder is packed onto the bottom portion. Tape with adhesive on both sides is placed on one of the flaps so that when the flaps are folded in overlapping contact over the insulation powder the powder is enclosed and the flaps remain secured to each other. Stitching may be added to further secure the adhered flaps to each other and to the bottom portion.

In a preferred embodiment, this invention allows buyers and sellers to communicate conditional early payment incentive offers to each other, and upon acceptance, to bind the other party to a contract. In a preferred embodiment, the apparatus includes a controller which transmits and receives conditional early payment incentive offers. Potential parties have the option to accept a conditional early payment incentive offer and thus bind the other party to a contract. The controller then facilitates payments between a buyer and a seller.

Abstract: An electric spoon for being played as a musical instrument. The spoon has a head and an elongate handle. A sensor is mounted to the spoon for sensing vibrations transmitted through the handle when the spoon is struck. The sensor emits an electrical signal in response to the vibrations. The signals are used by an amplifier that may be connected to the spoon. Spoons can be joined together. Rivets or other mechanical fasteners may be used to keep the spoons together as a spoon set. When this is done one spoon has a sensor and the other does not, but serves to make contact with the other spoon when either is struck. The joined spoons can be used by a novice spoon player because less dexterity is required to keep the spoons in proper position when being played.

Abstract: A hitch for coupling a trailer to a towing vehicle includes a hitch assembly and a base assembly. The hitch assembly pivots between an aligned position and a turning position as the towing vehicle turns. A bearing assembly rides between the hitch assembly and the base assembly. The bearing assembly guides the hitch assembly between the turning and aligned positions. The base assembly has an anchor assembly which prevents the hitch assembly from sliding fore or aft when in the aligned position.

Abstract: A blanking line including an uncoiler, a first feeder, a slitter, and a shear. A coil of metal is carried by the uncoiler. The first feeder removes the material from the coil and typically includes a leveler for leveling the metal. The metal is fed from the leveler into a looping pit that is located between the leveler and slitter. The slitter feeds and slits the material a predetermined distance and is driven with servo motors. The looping pit acts as an accumulator allowing the metal to hang so the slitter can move metal intermittently into a shear while the leveler runs at a constant rate. The shear cuts the material to a predetermined length corresponding with the distance that the material is fed by the slitter. A measuring wheel may be included to measure the distance that the material is moved by the slitter.

Abstract: An adjustable floor drain includes an adapter plate securable to a base imbedded within flooring. A locator ring overlays the adapter plate and the combined thicknesses of the locator ring and adapter plate are at least equal to the thickness of a covering over the floor. A grid plate overlays the adapter plate and is seated within the locator ring. The locator ring and adapter plate may be integrally formed as a single unit, and a frame member frames the drain to provide a neat, finished appearance.

Abstract: An electrical box mountable within a wall and installable from outside the wall. The box has a pan that includes a front flange for contacting an outer wall surface that extends outwardly from a sidewall. A back bracket is positioned opposite the front flange and adjacent to the back wall and a fastener having a shaft extends through the back wall to movably secure the back bracket to the back wall. No portion of the shaft extends behind the back bracket. The back bracket is movable relative to the pan between a first position adjacent to the back wall and a second position spaced farther from the back wall. The bracket and front flange are adapted for clamping a portion of a wall located between the front flange and back bracket when the back bracket is in its first position.

Abstract: A window cover for a military vehicle which includes armored plates angled away from an underlying vehicle window with reflectors, one of the reflectors being pivotable. The window cover allows an occupant of the vehicle to view outside the vehicle window as light is reflected off a viewing reflector to a stationary reflector and toward an occupant of the vehicle. A filter is placed between the viewing and stationary reflectors to filter out a portion of light reflected. The filter may also provide a collimation function.

Abstract: A machine and method for machining parts of partial revolution. The machine has a driving sheave rotatable about a first axis and a first driven sheave rotatable about a second axis fixed relative to the first axis. An eccentric link is rotatably connected to the first driven sheave at a pivotal connection that is spaced a predetermined distance from the second axis. A belt is wrapped around the driving sheave and the first driven sheave so that rotation of the driving sheave causes the first driven sheave to rotate. A second driven sheave is rotatable about a third axis fixed relative to the second axis. A second driven sheave contacts with the eccentric link. The eccentric link moves in a reciprocating motion when said first driven sheave is caused to rotate and causes reciprocating rotary motion in the second driven sheave, which is transferred to a part being machined.

Abstract: A gage for measuring deflection of a “mini-strip” used to determine peening intensity in small cavities and crevices of a work piece includes a pair of platforms made of a magnetic material spaced apart in a non-magnetic fixture a distance substantially the same as the length of the mini-strip. The platforms have a diameter slightly larger than the width of the mini-strip to provide support for both corners on each end of the mini-strip. A magnet for each of the platforms may be advanced toward and retracted from the platform to adjust the degree of magnetic attraction of the mini-strip. The platforms are stepped to define a shoulder and posts are offset from one of the platforms which cooperate to guide the user in proper placement of the strip. A plunger extended from the indicator engages the strip at substantially its midpoint, to thereby measure the deflection of the strip to give an indication of peening intensity.

Abstract: A multi-pane flush closing window assembly for a vehicle that has a body enclosing a passenger compartment is secured in an opening in the vehicle body by a clamp ring fastened to the interior wall of the vehicle body. The improved window assembly includes at least one fixed sub-assembly and at least one sliding sub-assembly supported by a frame. The fixed sub-assembly has a sash, and removable fasteners extend through the peripheral edge of the sash into the interior side of the frame so that the fixed sub-assembly can be independently disassembled from the interior of the vehicle without removing the frame or the clamp ring. The sliding sub-assembly is removably secured to the frame by an improved multi-piece guide track and slide pin assembly that allows removal of the sliding sub-assembly without removing the frame. The slide pins are removably secured to opposite sides of the sliding sub-assembly.

Abstract: A leak detecting hose for transporting fluid. The hose has an inner and outer layer. The outer layer circumscribes the inner layer. A transition layer is located between the inner and outer layer, and the transition layer provides a flow path for the fluid in the hose when the inner layer is breached. A first conductive wire is placed in contact with the transition layer, and a second conductive wire is placed in contact with the transition layer. The conductive wires are adjacent to and spaced from each other. When the inner layer of the hose is breached, the first and second wires will contact the fluid in the flow path. The conductive wires are radially equidistant from the center of the hose and helically wound around the inner layer. The transition layer may include reinforcement material, which can have filaments that provide a flow path for the fluid.
