Abstract: A removable orthodontic appliance which has a labial arch wire (20), continuous with a patient's anterior teeth surfaces, that is connected to a pair of clasps (32) seated over several midregion teeth. A pair of structural braces, either molded wings (36) or connecting sections (50), attach the clasps to a lingual arch wire (38) that is made of memory metal to optimize the force of the arch shape on the connected teeth. A bridge, formed by a radial loop (42), is connected between the braces and exerts persistent linear force to the teeth in the opposite direction of deformation. The loop is also preferably made of memory metal and has a constant tendency to return to its original shape, thus controllably effecting the desired tooth relocation. Another embodiment utilizes a number of radial arcs (56) between the molded wings that are placed angularly to not only move the teeth laterally, but retain an angular relationship with the roots of the teeth relative to the patient's basal bone structure.

Abstract: A combined mechanical and centrifugal clutch for a motor driven vehicle which has several original equipment manufacturer's components including an inside and an outside pressure plate (70), also frictional material for transmitting torque through the clutch. A lock-up housing (84) is attached to the outside pressure plate and contains a number of pivotally connected camming fingers (100) that force the outside pressure plate into tensional contact wit the frictional material by the camming force of the fingers caused by rotational centrifugal force. The operational portion of the mechanical clutch is unaltered permitting mechanical release of the clutch with the centrifugal portion added to lock-in the torque transmitting capabilities permitting increased capacity and positive engagement. Selecting the optimum rotational engagement speed is achieved by the use of weights and altering the springs or changing spring compressibility.

Abstract: An internal combustion engine valve actuating device located directly above each cylinder which has a co-axial venturi shaped duct (20) that is removably attached with threaded capscrews (24) and sealed with an o-ring (28). The interior of the duct contains a number of inwardly facing vanes (30) that hold an electromechanical valve actuator (48) complete with an engine intake valve (50). When a pulsed electrical signal is received by the actuator, opposed electromagnetic fields are developed reciprocating the valve. A fuel injection system introduces combustible fuel into the duct at the trailing edge of the vanes. The valve actuating device may also be applied to the exhaust system, less the fuel injection, and the valve actuator may be cooled by interconnecting cavities (60) within the vanes using engine coolant or oil.

Abstract: A fiberboard box formed from a blank (20), which includes side panels (24 and 28), also top and bottom flaps (40, 42, 44 and 46), with a pair of outer end panels (26 and 30). Mating inner overlapped end panels (48 and 50) produce a double fiberboard thickness on each end. Each corner contains a doubled vertical reinforcement (64) at an equal bisecting angle integrally formed from each outer end panel and adjacent side panel. A diagonal corner reinforcement (68) is formed from each overlap end panel and is angularly bent to span between the end and side panels and is also contiguous with the doubled vertical reinforcement. The diagonal and doubled reinforcement combination in each corner is attached together with glue where they touch each other, creating a rigid weight bearing corner permitting other like boxes to be stacked on top. Optionally, a number of stacking tabs (52) are formed in the end panels with mating recesses (54) maintaining alignment when the completed boxes are stacked.

Abstract: An electrical apparatus cover plate which has an enclosing base plate (20) mounted on a wall over electrical apparatus, such as toggle switches or convenience outlets. A slideable member, including a toggle actuator bar (42), nests within the plate and interfaces with the electrical switch toggle lever. A cap (26) covers and retains the bar which is longer than the base plate permitting the switch to be actuated by pushing the bar in a vertical direction transferring the movement to the switch. In another embodiment, the slideable member is a protective shield (50) that is retained through a dovetail arrangement provided in the base plate and covers a convenience outlet for protection also allowing the shield to be slid upward exposing the outlet and permitting an electrical plug to be inserted, also maintaining the uncovered position while in continued use.

Abstract: A siphon transfer, cooling tower sump water cleaning device, which has a cleaning nozzle attachment (20) connected to an extension tube (32) and a collecting chamber (44). The collecting chamber has a drain hose (52) threadably attached on the end and the entire device is placed under the sump water (38) of a cooling tower (34) for priming. The hose is placed below the water level and the nozzle is scrubbed against the bottom of the cooling tower sump (36). As debris and foreign matter is dislodged and is in solution with the water siphon action takes place drawing the mixture into the tube (32). At the end of the tube the inside diameter increases slightly in the collecting chamber and abruptly, yet smoothly, increases the velocity pressure in an elipsoidal shaped converging nozzle (50) where the increased velocity draws the debris through the remaining hose (52).

Abstract: A pouring extension for a liquid containing can which has a hollow cylindrical body (20) with an outward flare (24) on the top and an inverted cone shape (30) on the bottom. A number of outwardly extending projections (34) are formed integrally with the bottom portion of the body allowing the extension to be inserted into open can and snapping into place on the internal bead of the can. The rigidity of the body in combination with the tapered shape and fit of the projections creates a hermetic seal retaining the extension in the can allowing the contents to be poured without contaminating the rim of the can. The extension may be tilted to pour all of the paint over the inside bead of the can and the tapered configuration allows use with all nominal size cans regardless of the diametrical tolerance.

The hook closure tape is round and offset from the center of the lid to obtain maximum efficiency. Another embodiment locates the hook closure tape (24) on the flat end of a handle (38) picking-up a single pad by simultaneously rotating and exerting pressure on the uppermost pad in the stack housed in a packaged container.

Abstract: An improved motorcycle slider clutch which utilizes several original equipment manufacturers components, also an aftermarket basket (34), housing gear assembly (44) and a pressure plate (74). The pressure plate engages the nest of discs (32) when compressed by a number of fingers (82) configured to create linear force when subjected to centrifugal action. An enclosure (100) surrounds the basket (34) and retains the fingers. This action defines the first or mechanical stage of operation. A number of counterbalanced fingers (120) are also rotatably contained in the enclosure (100) but are held from engagement with a restraining hub (142) connected to a fluid pressurized cylinder (136). The second, or pressurized fluid actuated stage, is engaged electrically in a timed sequence relieving the pressure allowing the counterbalanced fingers to exert pressure on the clutch discs and plates at the optimum moment.
