Abstract: A removably attachable traction gear for the underside of footwear having two primary components: a retaining member and a receptacle. These two components respectively replace the common screw and threaded receptacle systems found in for affixing traction gear to the underside of shoes. A partial turn of the traction gear securely locks the gear into the receptacle. The retaining member has a three-extension design so as to make the traction gear resistant to lateral forces applied to the ground-engaging end of the cleat. Locking is achieved through use of cantilevered fingers which press in during installation of the retaining member, and which spring back out to lock with mated indentations in the extensions. During installation a dome containing insole material is compressed. Unlocking is achieved through reverse turning the retaining member to force the springs back in, and removal is aided through re-expansion of the dome. In a preferred form, the invention is utilized to attach a golf cleat to a shoe.

Abstract: A portable, self-contained vacuum device designed for hand-held use to create a moderate vacuum effect for various applications. A small diameter tube (10) is firmly attached (14) to the nozzle or spray tip of an aerosol canister and inserted at a point (16) through the wall of, and directed in one direction along the interior length of, a larger diameter tube (12). The tubes may be fixed to the exterior of the aerosol canister, may be detachable for storage, or may be manufactured into the interior of the aerosol canister. When propellant gas from the aerosol canister is released and injected out of the outflow end (20) of the smaller diameter tube toward one end of the larger diameter tube, the resulting aspiration of ambient gasses creates a vacuum effect at the opposite end, or intake end (18), of said larger diameter tube. A vented receptacle (22) is added to capture the aspirated debris and other matter, but allow the propellant and ambient gasses to pass into the atmosphere through filter screens (28) of desired permeability. The use of antiseptic additives with the aerosol propellant provides enhancement for use of the device for biological waste collection purposes. The use of preservative additives with the aerosol propellant provides enhancement for use of the device for specimen collection purposes.

Abstract: Phosphates can be removed from a hydrocarbon stream by contacting said stream with a ceramic formed of a basic material which is insoluble in the hydrocarbon stream. A ceramic as used in this patent document is a solid solution formed by calcination of a compound. The removal of the organic acid is accomplished at temperatures ranging from 20°C to 400°C, a preferred temperature is between 200°C and 370°C. A hydrocarbon stream consists of C5+ hyrdocarbons. The basic material can be made up of one or more alkaline earth oxides, alkaline earth compounds, alkaline metal compounds, group IIIA element compounds, group IVA element compounds, group VIA element compounds. Preferred alkaline earth oxides are sodium, magnesium, potassium, calcium, aluminum and silicon. The support for the basic material can be made from any inorganic oxide. A preferred composition is a combination of two or more alkaline earth oxides blended with an inorganic oxide support and calcined to form a ceramic material. The ceramic material should contain a large surface area and pore size to allow efficient removal of the organic acids. For example, the surface area should be at least over 50 m2/g, and the higher the better. The ceramic material should be placed in a hot hydrocarbon stream to facilitate the destruction and removal of organic acids within the stream. Application of the process to acids is also described.

Abstract: An improved rescue device for locating persons buried by avalanches operates in either a transmit mode or a receive mode. A first belt terminator is lockably engagable with a first belt terminator receptor on a case, and is associated with a power switch. The power switch switches between a power on position and a power off position in response to the engagement and disengagement of the first belt terminator with the first belt terminator receptor, and preferably is also independently manually operable. A second belt terminator is lockably engagable with a second belt terminator receptor on the case, and is associated with a mode switch. The mode switch toggles between a transmit mode position and a receive mode position, and preferably is also independently manually operable. A signal processing system generates a visual display which provides graphic information to expedite searching.      Prompt icons are displayed when a coarse search or a pinpoint search should be conducted, when the stage of a multistage amplifier should be changed, or when the rescue device needs to be reoriented to obtain maximum signal strength. Preferably, the signal processing system also displays the signal strength as a bar graph and displays an estimated distance to the buried transmitter.

Abstract: A method of enhancing oil recovery from an oil bearing formation through secondary fluid displacement. The method includes the step of injecting a second displacement fluid of a second density as a secondary fluid displacement into an oil bearing formation which has been subjected to a primary fluid displacement by a first displacement fluid of a first density from one of above or below a production zone. The first displacement fluid and the second displacement fluid are immiscible in oil. One of the first displacement fluid and the second displacement fluid has a density that is greater than oil and the other of the first displacement fluid and the second displacement fluid has a density that is less than oil. The secondary fluid displacement is in the same direction as the primary fluid displacement to displace oil remaining in the formation that was not displaced by the primary fluid displacement. The injection of the second displacement fluid is controlled to prevent displacement of substantial quantities of the first displacement fluid from the formation and avoid having to alter the position of the production zone as injection of the second displacement fluid continues.

Title: Domed compressed tampons
Inventor: HULL RAYMOND J JR
IPC: A61F13/20
Filed: 1998-03-25
Granted: 2007-04-03
Abstract: An improved apparatus and method compresses a cylindrical blank (24) into a tampon which is dimensionally stable and which is provided with a domed insertion end. A cylindrical blank (24) is radially compressed and then introduced into a cylindrical axial compression chamber (50). The blank (24) is then subjected to an exhume axial overcompression. The closed insertion end of the compression chamber has a bore formed therethrough. The bore is generally coaxial and is adapted to accept a reciprocating ejection ram (58) having a ram surface facing into the chamber. When the ram (58) is seated in the first position, the ram surface and the insertion end wall of the compression chamber together form a smooth doming surface. The bore periphery is of a smaller diameter than the chamber and hence radially spaced from the side walls of the chamber, and the ram has sufficient clearance to move through the chamber and eject the tampon without interference from the walls of the chamber.
