Abstract: A multi-piece ammunition cartridge casing includes a casing base extending along a central axis and defining an opening extending axially into the casing base from the distal base end. The inner casing surface defines a circumferential groove with a groove radius greater than a radius of an adjacent portion of the opening. The cartridge casing also includes a casing body with a proximal end portion disposed in the opening of the casing base. The casing body is secured to the casing base by way of a flange protruding radially outward in mating contact with the circumferential groove.

Abstract: A method and apparatus for treating water including a tank having an inlet and outlet and a water treatment material or resin within the tank. A control valve assembly having multiple, separable levels houses a water usage metering mechanism and a regeneration control mechanism, each having associated turbines. An inlet/bypass valve communicates source water with the tank inlet or directly to a system outlet. When the treatment material is exhausted, it is regenerated by actuating the bypass valve to communicate the source water with the system outlet. The turbine driven regeneration control then sequences the steps of regeneration, including opening a control valve to communicate inlet water to a venturi in order to aspirate brine solution and deliver to the tank outlet. The brine solution passes through the treatment material and is discharged through the tank inlet which is communicated to a system drain.

Abstract: A filter apparatus is provided which includes a first filter membrane element (40a), and a second bacterial filter membrane element. The first viral filter element (40a) is capable of treating water at a first second flow rate and is adapted to remove contaminants which are larger than a first size, while the second bacterial filter element (40b) is capable of treating water at a second higher flow rate and is adapted to remove contaminants which are larger than a second contaminant size. The first and second filter elements (40a), (40b) may be commonly housed within a sealed housing. An accumulating vessel (60) is placed in fluid communication with an outlet of the first filter element (40a) and an outlet of the second filter element (40b). The filter apparatus includes a duck bill type check valve (75) made of an antimicrobial material intermediate the second filter element (40b) and a dispensing faucet (70).

Abstract: A two bulb mercury vapor lamp apparatus includes a housing with a bottom whose cross-section forms a curved "M" shape. A pair of reflectors are attached to the bottom of the housing with each reflector positioned in one-half of the "m". The reflectors direct light from the bulbs onto a focal plane where a photosensitive material is located. A plurality of quartz liquid coolant circulating tubes are positioned between the bulbs and the photosensitive material which tubes both cool the lamp and filter out infrared rays. The coolant tubes are attached to a pair of end blocks which are removably secured to the housing. The end blocks, connected plumbing lines and coolant tubes can be lowered from the housing intact, thus greatly facilitating maintenance access to the bulbs and reflectors.

Abstract: A water treatment system including a plurality of treatment tanks containing a water treatment material and defining a fluid flow path through the material extending between a first tank port and a second tank port. A first remotely controlled three way valve associated with the first tank port controls the fluid communication of a source manifold and a regeneration discharge manifold with the first tank port of each tank. A second, remotely controlled three way valve controls the fluid communication of a product receiving manifold and a regeneration chemistry supply manifold with the second port of each tank. A regeneration control monitors the loading of each tank and initiates regeneration in a given tank when that tank reaches a predetermined exhaustion level.

Abstract: A water treatment system including a pair of tank assemblies 110, 112 interconnected by a valve module 114 for controlling the communication of water to be treated to an on-line tank and the regeneration of an exhausted tank. Each tank assembly includes a compartment containing a water softening resin 125 and a compartment centering an iron filter media. The valve module is connected to a regeneration solution reservoir 150 by brine conduits 164, 220. A pumping assembly 192 automatically transfers a predetermined amount of a supplemental regenerant fluid from a well 168 into the regeneration solution reservoir at the conclusion of a regeneration cycle. The pumping assembly includes upper and lower chambers 194a, 196a communicating with the supplemental regenerant fluid reservoir 168 and brine supply conduits 164, 220 respectively.

Abstract: A water softening apparatus and method for reducing odor in, and improving the taste of, problem water, including a pair of treatment tanks and a control valve assembly for determining which tank is on-line, and which tank is off-line, and for controlling the regeneration of the off-line tank. An exhausted tank is taken off-line and partially regenerated by communicating a regeneration solution from a reservoir to the tank and passing the solution through a resin compartment after which the solution is discharged to drain. After a predetermined quantity of regeneration solution is passed through the tank, the resin compartment is slowly rinsed using treated water from the on-line tank. Prior to fully rinsing the off-line tank, the fluid flow is terminated leaving a diluted regeneration solution in the off-line tank thereby keeping the off-line tank in a "high solids" condition.

Abstract: A deionization method and apparatus comprising separate cation and anion removing sections 10a, 10b, the cation section having separate tanks 14, 16 and the anion section having separate tanks 24, 26. Respective cation and anion control valve assemblies 18, 28 control the fluid communication between various components of respective sections and control the regeneration cycle of exhausted cation and anion tanks, respectively. Each valve assembly includes independent water usage monitoring devices 118 which, upon sensing a predetermined quantity of water discharge by its respective valve assembly, effects regeneration of an associated tank. An exhausted cation tank is regenerated by feeding cation regeneration fluid by way of the cation control valve assembly into the exhausted cation tank in a counterflow direction for a predetermined time. Decationized water from the on-line cation tank is then passed through the exhausted cation tank in a counterflow direction to effect a counterflow rinse.

Abstract: An improved water softener control valve having a housing defining a servo-control chamber that encloses concentrically mounted water usage and regeneration control discs. Each disc is incrementally rotatable by ratchet drives that are driven by water usage and regeneration control turbines, respectively, through associated reduction gear trains. The ratchet drive for the water usage disc includes a pawl that is engageable with the regeneration control disc, which upon predetermined movement in the water usage disc effects movement in the regeneration control disc to initiate a regeneration cycle. A rotatable insert is provided in the housing for manually rotating the regeneration control disc.

Abstract: An apparatus and method for incrementally advancing a shaft by a selected rotational amount. The apparatus includes a belt trained about a pair of space driven pulleys, the belt forming both first and second runs between the pulleys. Each pulley is associated with a shaft and is mounted for rotation in one direction only, with brake means designed to resist rotation of the pulley in the opposite direction. Means are provided for alternately deflecting the first and second runs of the belt to advance each shaft by an incremental amount in the one direction. In this manner, either or both shafts can be used for whatever purposes an incrementally advancing shaft is needed or desired.
