Abstract: A device for controlling the feeder system of pump-action shotguns having a breech-block which is operatively associated, by virtue of two braces, with a cocking rod (3) moving between two stroke limit positions of the breech-block, a closed position and an open position. The rod motion actuates the feeding of a cartridge from a tubular magazine (5) to a rising block when the breech-block reaches the open position and from the rising block into the firing chamber of the barrel (7) when the breech-block returns to the closed position. The device includes a limiter (9) for limiting the opening stroke of the breech-block and for selectively preventing the breech-block from reaching the open stroke limit position.

Abstract: A stormwater pollution separator and filter apparatus to be fitted inline in a stormwater conduit. The apparatus has an inlet (1) receiving stormwater and leading through an inlet aperture (3) to a separation chamber (4) which then leads to a filtration chamber (5) which is positioned below the inlet aperture (3). A riser (6) leads from the filtration chamber (5) to an outlet (7) which is connected back to the stormwater conduit (3). The inlet opening is connected tangentially into the separation chamber (4) to create, in use, a swirl action in the separation chamber (4) by reason of the flow of the stormwater. The separation chamber (4) is positioned vertically above the filtration chamber (5), and the filtration chamber (5) has one or more filtration baskets (9) positioned in the filtration chamber (5) to receive substantially all the flow of stormwater from the separation chamber (4), the baskets (9) are spaced apart from a wall (10) defining a periphery of the filtration chamber (5).

Abstract: In a sterilization method a plethora of magnetizable metal particles are deposited into a uterus of a living female organism. Subsequently, a magnet is placed near an external skin surface of the female organism near the uterus to thereby cause at least some of the metal particles to embed in a myometrium or endometrium of the uterus. The metal particles may be magnetized prior to deposition in the uterus. The particles are advantageously formed to have a sharp end which easily penetrates into the uterine lining. Each particle is magnetized so that the sharp end has a predetermined magnetic pole, whereby a magnet with the opposite pole placed against the organism results in an embedding of the sharp end in the uterine lining. In addition, microwave radiation is optionally transmitted into the female organism in a region about the uterus after the embedding of the metal particles in the myometrium or endometrium.

Abstract: A method for preserving the temperature integrity of cryogenically preserved biological samples is presented, involving initiating a countdown sequence upon removal of a sample from a controlled portable or bulk storage environment, requiring operator action to terminate the countdown on restoration of the sample to a controlled environment. Audible and visual warnings are provided to an operator prior to attainment of a critical temperature, beyond which damage may accrue to the sample. A portable device facilitating execution of the method is described.

Abstract: A wastewater treatment system has a tank and at least one baffle disposed in the tank so as to subdivide the tank to form a treatment chamber and a clarification or settling chamber. The baffle is inclined relative to vertical, so that the clarification chamber tapers from an upper end to a lower end. The lower end of the clarification chamber is provided with a plurality of mutually spaced orifices or apertures communicating with a lower region of the treatment chamber, so that sludge settling in the clarification chamber is directed to the lower region of the treatment chamber via the orifices. The clarification chamber is further provided at its lower end with a plurality of substantially vertical partitions defining a plurality of hoppers communicating with respective orifices for guiding sludge to the orifices. A recycle pump and a distribution manifold serve to recycle wastewater from the treatment chamber to the clarification chamber.

Abstract: A suspension of animal cells is incubated with supports to adhere the cells to the supports. Preferably, the supports have pores that provide pore volume, and the cells are grown during incubation until most of the available pore volume is filled with cells. An encapsulating layer is then formed around the supported cells by exposing the cells on the supports to a reactive gas composed of a carrier gas such as sterile air saturated with an inorganic alkoxide followed by treatment with steam to hydrolyze residual alkoxide groups. The encapsulated cells are stored by immersion in culture media. The cells may be in the form of cell aggregates, and the supports can be sterilized. The supports and encapsulating layer can have pores of a size that permit free exchange nutrients and metabolic products, and excludes the cells from contacting antibodies or immune cells when implanted. The encapsulated cells can used in an extracorporeal device or implanted directly.

Abstract: As has been established, the use of energetic materials, generated by manufacturer's excess and/or demilitarization projects, as ingredients in commercial blasting explosives is a feasible and environmentally acceptable method of handling them. Ammonium picrate is used as an explosive charge in the manufacturing of conventional ammunition rounds, such as large caliber navy guns. The present invention is directed to the use of recovered ammonium picrate in commercial blasting agent compositions, that include watergel slurries, ANFO, HANFO-blends and emulsion based blasting agents. These new blasting agents exhibit favorable cost for performance characteristics and have found a use for recovered ammonium picrate, which would heretofore have been incinerated or otherwise disposed of at significant cost.
