Abstract: A system and method of economically converting a spent first pickling acid solution that contains hydrochloric acid, water and ferrous chloride into a suitable second pickling solution. Sulfuric acid is added to the first pickling acid solution. This produces a regeneration solution. In the regeneration solution, the sulfuric acid reacts with said ferrous chloride and water to produce ferrous sulfate heptahydrate and hydrochloric acid. The regeneration solution is cooled to promote precipitation of the ferrous sulfate heptahydrate from the regeneration solution, therein creating ferrous sulfate heptahydrate crystals and a second pickling acid solution. The second pickling acid solution contains both hydrochloric acid and sulfuric acid. The ferrous sulfate heptahydrate crystals are separated from second pickling solution. The ferrous sulfate heptahydrate is sold commercially and the second pickling acid solution is used to directly pickle ferrous metal.

Abstract: A system for detecting radiation that is embodied within a trash collection truck. The trash collection truck has a storage bin for holding compressed trash and a collection bin for temporarily holding newly collected trash. A compaction mechanism is used to move newly collected trash out of said collection bin and into said storage bin. At least one sensor is placed proximate the collection bin for detecting radiation. If radiological waste is placed into the collection bin of the trash collection truck, the sensor detects the presence of the radiological material and activates an alarm indicator. The alarm indicator warns the operators of the trash collection truck that radiological waste is present.

Abstract: A carrying case assembly for a drilling tool and the method of interconnecting the carrying case with the drilling tool. The carrying case defines an internal area with a least one first vertical side. A press mechanism is attaches to the vertical side of the carrying case. The press mechanism includes a geared element, wherein said geared element partially extends through the first vertical side of the case. A guide bracket is provided that includes a sliding element, a section of gear rack and a drill mounting clamp. The sliding element engages the first vertical side of the case and enables the sliding element to reciprocally move along the first vertical side of the case. The section of gear rack engages the geared element. As such, when the geared element is rotated, the sliding element is caused to move.

Abstract: A beach cart for carrying equipment along a beach. The beach cart has a frame and two wheels that support the frame. This allows the beach cart to roll freely along a beach. The beach cart has at least one fishing pole tube coupled to the frame so that the frame can hold fishing poles during fishing. Since the frame is supported upon two wheels, it is unstable. A stabilizing leg is therefore provided that has is coupled to the frame at a pivot connection. The stabilizing leg can be selectively rotated about the pivot connection between a raised position and a lowered position. The stabilizing leg and the two wheels combine to form a tripod support for the frame when the stabilizing leg is in its lowered position. The beach cart can therefore be made highly stable when unattended.

Abstract: A self-standing display device for providing a viewer with a printed image which can be easily removed from any print medium such as a magazine or book, simply folded and placed on self-standing long term display. The self-standing display may have support panels with a straight or flat base in which case it forms a stationery display or it may have side support panels with a curved bottom edge in which case it forms a display which can be rocked back and forth to enhance the display of animated or other specialized images.

Abstract: A device and method for helping a floral designer create a floral arrangement that is well balanced in its distribution of flowers and greens. The device includes a three-dimensional foam structure that has a plurality of different levels. Each of the different levels is of a different size, thereby creating an overall tapered foam structure. Areas of equal size are demarcated on each of the different levels. The areas of equal size are evenly distributed around a plurality of different levels. The demarcation of the various equal sized areas are created either by using an external grid work that lay over the foam structure or shaping the foam into protrusions on each level. Using the equal sized areas as a distribution grid, a floral designer can quickly and easily place flowers and greens throughout the three-dimensional foam structure in a manner that is evenly distributed and well balanced.

Abstract: A system and method for providing a dry consumable with a liquid in the same assembly. The assembly includes a fluid container that is covered with a cap assembly. The cap assembly can be manually opened and closed, thereby selectively controlling the flow of fluid out of the fluid container. Consumable material is formed into a solid form on the exterior of the cap assembly. The material can include pharmaceutical compounds, nutraceutical compounds or can be inert compounds, such as confections. The material is formed into a solid that can be bitten or licked away from the cap assembly as the cap assembly is placed in the mouth. Once the material is received into the mouth, liquid can be drunk through the cap assembly to help wash the material down the throat.

Abstract: An environmental control system for an aircraft having an air pump that is powered by bleed air from an engine of the aircraft. Although the air pump is powered by engine bleed air, the air pump draws ambient fresh air from outside the aircraft, compresses the fresh air to a predetermined pressure and pumps compressed fresh air into the pressurized cabin of the aircraft without ever exposing the fresh air to the compressed engine air. To heat the compressed fresh air, heat from the engine bleed air can be transferred to the compressed fresh air with a heat exchanger. However, although heat is exchanged between the engine bleed air and the compressed fresh air, the two flows of air are kept separate and are never mixed.

Abstract: A trail marking system having a plurality of trail markers, a remote control handset for selectively activating the trail markers, and a setting tool for setting and removing the trail markers. To use the trail marking system, a hunter attaches a trail marker into a tree using the setting tool. The trail markers contain externally perceivable indicators that can be selectively turned on an off. When the indicators in the trail markers are off, the trail markers are inconspicuous. However, when the indicators are activated, they are highly visible. The trail markers are selectively turned on an off using the remote control handset. As such, a hunter can selectively turn on and off the trail markers as he/she walks along the trail.

Abstract: A carrying case device for a circular saw and the method of interconnecting the circular saw with the carrying case device when the circular saw is in use. A case is provided having a top surface, wherein the case defines an internal area large enough to store the circular saw. A miter assembly is provided that is attached to the top surface of the case. The miter assembly can be rotated on the case. The miter assembly also includes a guide arm that can be lifted and closed about a hinge connection. The guide arm contains a mounting receptacle for selectively receiving and engaging the circular saw. As a result, the circular saw can be raised and lowered against a work piece as though it were a power miter saw.
