Abstract: A repositionable downspout extension is formed as an integral blow molded plastic component having three distinct sections. A downspout connector end merges with a corrugated extendible middle section which terminates in a drainage pipe connector. The downspout connector includes two rectangular sections of different sizes defining two different securing segments for engaging two different sizes of downspouts. The middle section is of a pleated configuration and is of variable length by expanding or collapsing of the pleats. The drainage pipe connector is a circular connector for connecting with commonly used corrugated plastic pipe or rigid plastic pipe. In a preferred embodiment the downspout connector end also includes a connector for insertion and retention in the corrugated middle section.
Abstract: A fluid pressure system (S) includes a flexible diaphragm bladder (172) located inside a pressure tank (164) installed within a fluid system such as well (168). In preferred aspects, the bladder (172) can be inflated by the introduction of air and is located within a flexible confining tube (198) for preventing over expansion of the bladder (172) and in the preferred form being of a cylindrical configuration and arranged concentrically around the bladder (172). The bladder (172) and the confining tube (198) are free floating in and without physical connection with the pressure tank (164) in preferred forms. The pressure tank (164) includes a flexible side wall (196) to allow folding or willing of the assembled fluid pressure system (S) in preferred forms.
Abstract: A protective sleeve system for use by plumbers during installation of riser pipes in buildings, surrounds a pipe and maintains a space around the pipe. A sleeve surrounds the pipe such that a space is defined between the pipe and the sleeve and a plurality of spacers disposed between the sleeve and the pipe, maintain the space between the pipe and the sleeve. The plurality of spacers are separate from the sleeve. An annular cover ring covers the annular space. In use, the protective sleeve system is installed prior to pouring the concrete floor. After pouring and setting of the concrete floor, the cover ring is removed, followed by the removal of the spacers. The sleeve is then cut to floor level and the pipe riser is cut down to a suitable level.
Abstract: Some embodiments of the present invention provide an accumulator tank assembly and method in which a flexible bladder is received within an accumulator tank. The accumulator tank and the flexible bladder can each have an inlet aperture through which fluid is received within the accumulator tank assembly and an outlet aperture through which fluid exits the accumulator tank assembly. In some embodiments, inlet and outlet flanges positioned adjacent the inlet and outlet apertures of the accumulator tank are used to couple the flexible bladder to internal or external surfaces of the accumulator tank, thereby creating fluid tight seals between the flexible bladder and the accumulator tank.

Abstract: A spraying cap for a spray container with a valve includes an attachment for the spray container with a connection piece that is connectable with the valve, which runs into a spray nozzle. The spraying cap further includes an actuator element, slewably mounted on the attachment, which in a locked position at least partly covers the spray nozzle and in an opened position sticks off from the spraying cap, and a pressure region in the attachment proximate to the connection piece. A force on the pressure region or on the actuator element in its opened position, wholly or partly pointing into the actuation direction of the valve, opens the valve.
Abstract: A flow control valve controls a flow of water through a passage to a brine tank of a water treatment apparatus. A valve seat is between first and second sections of the passage. The valve seat has a first end with a concave surface facing the first section and an aperture extending from the concave surface to a second end that faces the second section. A groove in the concave surface extends from the first end to the aperture. A valve element moves within the first section in response to pressure of the water in the first section thereby varying the size of a path through the passage by an amount that varies as a function of the water pressure. The action of the valve element maintains a substantially constant flow rate through the flow control valve regardless of water pressure variation.

Abstract: An apparatus converts rotary motion of a motor drive shaft into oscillatory motion of a work piece, for example, in a power tool. The apparatus comprises a planetary gear assembly connected to the motor for rotating an output gear. The output gear meshes with a drive gear including a drive pin. The drive pin fits in a yoke slot for reciprocation of the yoke upon rotation of the drive gear. The yoke is operatively connected to the work piece. An air flow system cools the power tool housing. The housing has an inlet aperture in the handle portion and an outlet aperture for placing the interior of the housing in communication with the atmosphere. A wall integral with the handle portion engages the body of the motor housing between a first end and openings in the body. The wall provides a barrier to minimize air flow between an intake air portion of the interior of the housing and an exhaust air portion.
Abstract: A composite strip 10 windable to form a helical pipe is disclosed. The composite strip 10 comprises: an elongate plastic strip 11 having a base portion 12 and at least one lengthwise extending rib portion 20 upstanding from the base portion 12; and an elongate reinforcing strip 30 extending lengthwise and supported laterally by the rib portion 20, the reinforcing strip 30 having a height to thickness ratio of at least three to one and orientated substantially perpendicular to the base portion 12. When wound into a helical pipe, the reinforcing strip 30 reinforces the pipe against radial crushing loads. A bead 40 seals the reinforcing strip 30 from the environment. Desirably the composite strip 10 further comprises: a planar lamina 50 extending lengthwise and bonded to the base portion 12, the lamina 50 having a higher Young's modulus and strength than those of the plastic strip 11. The lamina 50 greatly improves the pressure rating of a pipe wound from the strip 10.

Abstract: An intake tubing includes a tubular member having a number of helical protuberances and a number of helical grooves formed in an inner peripheral surface, an inlet end for receiving fluid, and an outlet end for coupling to an engine. The helical protuberances and the helical grooves of the tubular member may guide the fluid to flow through the tubular member in great speed and to increase power of the engine when the fluid flows quickly toward the inlet end of the tubular member, and to generate eddy current and to lower the flowing speed of the fluid when the fluid flows slowly toward the inlet end of the tubular member, in order to economize fuel or fluid.

Such a fiber reinforced hose has excellent heat resistance, tensile strength, and adhesiveness with the rubber layers, as well as durability against repetitive pressurizations.
Abstract: A hydroaccumulator, in particular a bladder accumulator, includes a pressurized container (1) and a separation element (5) located in the container to separate a gas chamber (7) lying adjacent to an inlet on the gas side from a fluid chamber (9) lying adjacent to an inlet on the fluid side inlet (3), having a fluid connecting sleeve (11) and a valve arrangement located in the connecting sleeve (11). The valve body (17) has a transversal bore (33). The valve body is pretensioned in an open position which allows the passage of fluid and can be displaced into a closed position by a displacement of the separation element (5).
