Abstract: Negative pressure is: (a) applied through a shallow manifold inlet fitted between the rear of a toilet porcelain bowl and hinged seat; (b) created by a remote blower; (c) conveyed via conduit. An adjustable hood in front of the manifold optimizes odor collection. The blower can be located in a housing possessing multiple inlet ports for connection to a plurality of manifolds. The blower can also be used in line with conduit and multiple blowers utilized. A sensor port in a manifold extension facilitates empirical verification of air flow. Electrical supply to the blower can be controlled by a light switch: (a) independently; or with: (b) a vent that can be exhausted through the same conduit, or (c) a humidity blower. Plastic and metal conduit of differing cross section are joined with an adapter and either connected to a blower housing inlet port. PVC conduit is disposed within wall frames hung from the sill.

Abstract: A toilet tank flush valve structure includes a valve base for installation in the outlet hole formed in the floor of a toilet tank and defining a water outflow passage and including a first valve member at the upper end of the water outflow passage. A float assembly is movable relative to the valve base between a sealing position in which a second valve member at a lower end of the float assembly engages the first valve member in sealing relationship and a flushing position in which the second valve member is spaced upwardly from the first valve member. The float assembly includes an outer shell that is open downwards and has a lower edge at which the shell is provided with the second valve member, and a closure member within the outer shell and cooperating with the outer shell to define a float chamber. The closure member is adjustable in position relative to the outer shell, whereby the float chamber is adjustable in volume.
Abstract: Apparatus and methods include an array of a plurality of individual air injector nozzles are integrally connected to a common air flow tube. The individual nozzles include an integral attaching plate and an integral air injector tube in addition to the common air flow tube with the individual nozzles spaced along the common air flow tube. A plurality of arrays can be joined together to form an entire arrangement of any desired configuration of individual air injector nozzles that can be applied as a complete unit to a tub or spa. One or more of the arrays can be cut across the common air flow tube to achieve the exact number of individual nozzles required in accordance with the desired arrangement of air injector nozzles. The arrays, including the cut arrays can be joined together at a location other than at the tub or spa and then transferred as a complete unit to be attached to the tub or spa.
Abstract: A hot tub or spa (100) has a vanishing or overflow edge (110) not readily visible to a user. Water from the main holding area (101) overflows the edge (110) into a catch basin (102). A reservoir (120) holds a constant head of water to provide to a pump (112) and also allows for the holding of increased amounts of water displaced by users who are using the hot tub (100). Water flowing over the vanishing edge (110) flows into the catch basin (102) and thence to the reservoir (120) and pump (112) where the water is recirculated into the spa (100).
Abstract: A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable valve support. If desired, one or more anchor may be used. The valve support, which entirely supports the valve annulus, valve leaflets, and valve commissure points, is configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the assembly is properly positioned. The anchor engages the lumen wall when expanded and prevents substantial migration of the valve assembly when positioned in place. The prosthetic valve assembly is compressible about a catheter, and restrained from expanding by an outer sheath. The catheter may be inserted inside a lumen within the body, such as the femoral artery, and delivered to a desired location, such as the heart.
Abstract: A vehicle-mounted conveyor system including an infeed conveyor assembly mounted for powered rotation relative to the vehicle. The conveyor system includes a discharge conveyor assembly pivotally mounted to a main turret, which in turn is mounted to a primary turntable for powered rotation relative to the vehicle. The discharge conveyor assembly includes a telescoping boom and a moving discharge conveyor belt to supply an aggregate material, such as concrete, to a desired point at the work site. An infeed conveyor assembly is rotatably mounted to the main turret by a powered secondary turntable. The powered secondary turntable is mechanically driven by a drive mechanism, such that the infeed conveyor assembly can be rotated relative to the main turret. The secondary turntable and the primary turntable are independently operable and rotate about a common vertical axis, such that the infeed conveyor assembly and the discharge conveyor assembly can be independently rotated relative to the vehicle.
Abstract: The present invention provides a small electric blind rivet setting device that is capable of being driven by a battery and that does not require a pathway for recovering the broken mandrels to be provided in the motor shaft. A recovery container 10 is provided in a tool housing 27 forward of an electric motor 13 in the axial direction, and a spindle 14, which rotates because of the rotation of a drive shaft 18 connected to the electric motor circumventing the recovery container, is connected so as to move a pulling head (30) in the axial direction. The positive rotation, stopping of rotation and reverse rotation of the electric motor are controlled by a pulling operation on a trigger and detecting the position of the pulling head in the axial direction.

The first portion of the butt-strap is connected to the distal portion of the skin such that a junction is formed between the exterior surface of the skin and the exterior surface of the first portion of the butt-strap. The exterior-facing surface of the distal portion of the skin is of a shape complementary to the shape of the interior surface of the first portion of the butt-strap. The first portion of the butt-strap tapers towards its distal end such that, at said junction, the exterior surface of the skin and the exterior surface of the first portion of the butt-strap form a substantially continuous exterior surface.
Abstract: A pump assembly comprising a stator and a rotor having vanes of opposite handed thread arrangements is described. A radial gap is located between the stator vanes and the rotor vanes such that rotation of the rotor causes the stator and rotor to co-operate to provide a system for moving fluid longitudinally between them. The operation of the pump results in a fluid seal being is formed across the radial gap. The described apparatus can also be operated as a motor assembly when a fluid is directed to move longitudinally between the stator and rotor. The presence of the fluid seal results in no deterioration of the pump or motor efficiency, even when the radial gap is significantly greater than normal working clearance values. Furthermore, the presence of the radial gap makes the pump/motor assembly ideal for deployment with high viscosity and/or multiphase fluids.
