A draw holding and draw releasing mechanism assembly comprises a mounting bracket, with a passageway controlled by a levered cam, secured to a bow. A draw bar is movable and lockable within the passageway by the levered cam. The draw bar includes a hand grip and an adjacent linear slot with an adjacent cam member, having a cradle notch and finger grip. The cam member rotates from a bowstring accepting position, with the cradle notch open to the draw bar slot, to a bowstring retaining position, w...

A process and apparatus for protecting a media bed filter with underlying support screen from solids contained in a liquid, such as filtrate from the filter, used to regenerate or backwash the media bed filter. Filtrate enters a first collection chamber containing a screen assembly covering one outlet, the chamber also containing a second outlet. Filtrate traverses the screen assembly and is transferred to a second collection chamber with addition of a predetermined amount of bactericide to prev...

A method for operating a continuous wet oxidation system for destroying cyanide in caustic cyanide and metal wastes which scale upon heating. Raw waste is introduced into the wet oxidation reactor without heating while a mixture of heated dilution water and oxygen containing gas is introduced into the reactor by a separate inlet. The reactor is fitted with a pair of valved effluent lines and corresponding valved lines for introducing dilute mineral acid into each effluent line at system pressure...

A telephone interface device adapted for the transmission of recorded audio files over communication channels is disclosed. The telephone interface device comprises electronic circuitry contained within a case member. The circuitry includes a plurality of electrical connection jack members, each accessible via an aperture in the case member, with each electrical connection jack member in communication with at least one control switch member mounted in an aperture in the case member and operable ...

The invention is a building panel and clip system, in which the building panel members are quickly and reversibly attached to other similar building panel members with clip members to form a temporary structure that provides shelter from the elements. Alternatively, the building panel members are erected interior an existing structure to provide partitioning of the space therein. The building panel members are used to form both vertical walls and the roof for such an exterior structure. The buil...

A method for making beaded jewelry is provided. The method utilizes a megaphone shaped device having a small diameter first end and a larger diameter second end. The circumference of the first end is that of one part of the human body, such as a child's wrist. The circumference of the second end is the size of another part of the human body, such as an adult ankle. Markings on the girth of the device sequentially graduate in circumference and define graduated bracelet, anklet and other jewelry s...

A firewood bundler device includes a base member having first and second opposed, vertical arm members extending from the base member. A U-shaped, wood support member is attached at an end of each arm member, with an open end opposite the base member. A wrapping support member is rotatably attached to an end of one arm member and includes a spindle section extending therefrom, the spindle section movable in a circular path around the wood support members upon rotation of the wrapping support mem...

A portable shooting bench assembly has a base chassis assembly with a wheel member that contacts a support surface upon elevating one end of the base chassis assembly. An L-shaped turret chassis member is pivotally mounted at a first end to the base chassis assembly and follows the contour thereof. The turret chassis member's second end is supported on a roller member that contacts the base chassis assembly with a seat member secured above the roller member. The first end of the turret chassis m...

A single-stage continuous aeration-batch clarification process for purifying wastewater containing pollutants includes the steps of continuously aerating the wastewater in the presence of biologically active solids and powdered absorbent in an aeration zone. A portion of the mixture of wastewater, biologically active solids and powdered absorbent is transferred to a settling zone where a settled solids phase and a clarified liquid phase are formed. During the settling step additional wastewater ...

An improved method for maintaining a granular medium filter in a clean, operable condition is disclosed. The time interval required for the level of liquid above the filter bed to drain from a backwash outlet level to the upper bed surface level following a backwash cycle is monitored. Upon this measured draindown time exceeding a predetermined interval of time, a chemical cleaning cycle is initiated for the granular medium bed filter.
