Abstract: An animal feed apparatus comprises in combination, a circular container having a peripheral sidewall closed by a bottom panel, and at a top end outwardly extending with an integral lip. An interior surface of the sidewall is formed with an inwardly directed slope, and a lid provides an annular lip having a pair of annular, outwardly facing and outwardly extending, spaced apart ribs positioned for intimate frictional contact with the sloped sidewall of the container and adapted for vacuum engagement with the container so as to seal an interior space of the container.

Abstract: A housing for purifying an air flow moving through it provides a reception space for receiving the air flow. The air is treated with mechanical filtration of particles larger than approximately 2 micron, ionizing with energetic ions, exposure to ultraviolet light radiation, and electrostatic precipitation of particles in the air inflow. The ionizing and UV bombardment of the air inflow occur simultaneously.

Abstract: A ballistic panel comprises a monolithic epoxy bonded plate made up of laminated individual panels integrally encased within a composite plastic outer shell. At least one of the individual panels is comprised of an integral laminated stack of individual layers of composite and metal construction. An outer layer of composite plastic is used to enclose the structure. The panel achieves high strength, light weight and low cost in construction.

Abstract: A manually pressurized water filtering container comprising an enclosure having a compressible wall terminating at an open neck and a removable, water permeable filter module and a cap adapted for receiving the filter module and for engaging and sealing the open neck. A sealing gasket is compressed between two sealing surfaces in one case by a retainer and in another case by the engagement of the cap on the container. Water forced out of the enclosure by compression of the wall moves through the filter module to reach the open neck and the cap.

Abstract: Two chambers in a container are separated by an easily replaced filter. One of the chambers is capable of being compressed so as to pressurize a water volume in the chamber which is to be filtered. The water is therefore forced through the filter into the second of the chambers where it is stored for use in a clean and drinkable form. The filter is made-up of a series of discs arranged to effectively remove particulate, chemical and other undesired contents of the water. The filtered water may be filtered to the molecular level providing an essentially sterile drinking water. The filter may also remove odor and taste components that are undesirable. The filter is constructed and held within the container in such a manner as to prevent seepage and leakage of the unfiltered water.

Abstract: An elongated magnetic assembly has an outer case enclosed by two end caps all of a non-magnetic, corrosion resistant and highly rigid structural material. The interior of the case provides a pair of magnets separated by an iron bearing spacer having contact with magnetic pole surfaces of the magnets. Two iron bearing pole keepers are place on the opposing pole surfaces of the magnets. The magnetic circuit is such that the device attracts debris forming a ball over time so that there is less likelihood of a sharp objects puncturing the stomach wall of the animal.
