Creation of internal underwater falls and generation of electrical energy therefrom includes providing a hollow tank having a substantially vertical axis; locating a rotatable turbine in an interior of said tank and orienting said rotatable turbine so that its axis of rotation is an axis selected from consisting of a vertical axis of rotation and a horizontal axis of rotation; providing a directional flow of water into said tank forming a directional underwater fall in said tank, and directing the underwater fall onto blades of the turbine to rotate the turbine; connecting an electrical generator with a shaft of the turbine so that the rotation of the shaft of the turbine is transmitted to the electrical generator which thereby generates electricity; and evacuating water from an interior of the tank after water passes through the turbine, so as to leave under the turbine a space sufficient for a continuous flow of water into said tank, formation of the underwater fall into said tank, and flow of water out of said tank.

Method and apparatus for creating internal directional underwater falls and generating electrical energy therefrom

Generation of electrical energy from water is performed by submerging a tank having an inlet and an outlet in a body of water so that the water inlet is located under a water surface and covered by water, and water flows thereby into an interior of the tank, evacuating water from the tank through the outlet to maintain in the interior of the tank a space for flowing water through the inlet into the interior of the tank; and arranging a converting unit which converts energy of the water flowing into the interior of the tank into an electrical energy.

A portable dolly, has a substantially horizontal platform having an upper surface and a lower surface, a plurality of wheels provided on the lower surface of the platform, and a handle connected with the platform so as to be turnable between a substantially horizontal position in which the handle is located in the vicinity of the platform substantially coextensive with it and a substantially vertical position in which the handle extends substantially perpendicularly to the platform, the platform being provided in the region of the upper surface with a groove formed so that when the handle is in the substantially horizontal position it does not extend upwardly beyond the upper surface of the platform.

A composite antenna comprising a first and second antenna suitable for transceiving independent signals in the cellular communication and GPS bands. The first antenna has upper and lower electrically conductive discs of substantially the same size aligned substantially in parallel, a first means for application of a first electrical signal between and at substantially geometric centers of the discs, and a plurality of electrically conductive shunts. The second (GPS) antenna is attached atop the upper electrically conductive disc and has a second means for application of a second electrical signal to the GPS antenna which traverses the electrically conductive discs whereby there is no significant degradation in performance of either the first cellular antenna or the second GPS antenna. The shunts are electrically connected to the first electrically conductive disc and the second electrically conductive disc, whereby the first and second electrically conductive discs are spaced from each other by a volume of free space or a volume occupied by a dielectric material. Also described is an antenna for cellular communications alone, with first and second electrically conductive discs spaced from each other by a volume of free space or a volume occupied by a dielectric material, without the second GPS antenna.

An exercising device for exercising while doing office work has an exercising element for exercising a part of a user's body while a user works at an article of office furniture, and an element for connecting the exercising element with the article of the office furniture so that the user can do office work at the article of furniture and simultaneously exercise the part of his body with the exercising element.

A valve for distributing pressure air to remove lint from a knitting machine at locations where it typically accumulates, in which plural balls are normally seated in valve openings to close the flow passages to these locations and are unseated therefrom to allow the flow of pressure air when contacted by a rotating arm. Control over the movement of the ball is exercised by the seating of the ball not only in a horizontally oriented valve opening, but also in an opening of a vertical wall adjacent to the valve opening, so that the two noted horizontal and vertical openings positioned about the ball provide a desired position to the ball, and the projection of the portion of the ball through the vertical opening presents it for unseating contact by the rotating arm.

A knitting machine attachment using pressure air flow through, and discharging from, plural flutter tubes to control the accumulation of lint. Each individual tube construction consists of an inner circular bore and an encircling eliptical wall which causes a flutter or pivotal traverse in a specified plane or path, namely that in favor of the weaker or thinner walls of the tube. This maximizes the amount of discharging pressure air that can be directed against specific locations where lint is likely to accummulate.

A support structure having a pair of semi-circular members with a 'C' shaped cross section which house a plurality of tubing which delivers air to a knitting machine to blow the lint therefrom.

A split nut assembly for mounting on a threaded stud or shaft without passing over the end of the stud or shaft. The assembly consists of a nut divided into two equal parts and a shell equally divided. The shell when assembled fits over the nut so that the assembly can be rotated and tightened together. In a separate embodiment, lock nut capability is provided by providing tapered surfaces on the shell and the nut to force the latter radially against the stud or shaft while the assembly is tightened in place. In another embodiment, a press fit arrangement is provided.

A control system for an automatic damper in a heat generation system. The damper is provided with a spring biasing arrangement to open the damper when the plant is generating heat to permit unobstructed discharge of the products of heat generation. A motor maintains the damper closed when no heat is being generated. Provision is made for disabling the control system permitting the damper to be opened by the spring and the heat generator to function normally when a malfunction occurs in a switch which normally performs in a safety capacity. Included in this arrangement is a fuse in a circuit which opens the circuit when the switch fails as the result of a short circuit or welding of the contacts. The circuit includes means for preventing short circuiting during normal operation.

A flexible child's slipper (10) has a night light (12) associated therewith which may be selectively actuated by each step of the child as the slipper (10) flexes with each step. The night light (12) includes a hollow transmissive three dimensional character rendition which contains an illumination apparatus (26) inside. The illumination apparatus (26) comprises a transparent waterproof housing (28) which is formed of plastic except for a rubber seal (30) forming part of the surrounding wall. The housing (28) contains a light source (32), a battery (34) and a switch (40). A resilient pusher member (50) having a protrusion (56) is mounted on the front portion (20) of the slipper (10) and is disposed adjacent the switch (40) to act on the switch (40) and close it through the seal (30) during each step to illuminate the light source (32). A day/night mode switch (44) is provided to selectively disable the operation of the light source (32) to prevent its operation by the flexure switch (40) by disrupting electrical contact with the battery (34) in the day mode.
