Abstract: A fluid filter and a method of constructing a fluid filter which will independently retain itself in a fluid passageway includes a sheet of filter media and a retainer which is attachable to one side of the filter media. The retainer may be sized to frictionally engage the walls of the fluid passageway or may be of a resilient material which allows the retainer to resiliently engage the walls of the passageway. The retainer is attached around only the periphery of the filter media with the central portion of the filter media being free with the respect to the retainer. The filter media has flexible edges which extend beyond the retainer to seal the passageway so that all fluid flowing through the passageway will flow through the filter media.

Abstract: A wear-resistant copper-base sintered oil-containing bearing material having a structure which contains 2 to 11 % by weight of tin and 1 to 20 % by weight of cobalt and further includes 2 to 15 % by weight of at least one of molybdenum disulfide, graphite and lead serving as solid lubricants. Disperesed throughout that structure is cobalt at an average particle size equal to or less than 20 .mu.m.
Abstract: A way is provided for controlling mosquitoes within the human being is simulated to attract mosquitoes away from areas of human gatherings, such as backyards and the like. A solution of lactic acid in water is prepared and heated to simulate the body temperature of a human being, and a fan or blower is provided to direct the lactic acid molecules away from the areas of human habitation so that mosquitoes or other pests can be subsequently destroyed by heat, electrocution or the like.
Abstract: The reversible endless screw slides are fixed by their lower fixed elements to the vehicle floor via a base plate. The base plate is mounted under at least one of the two slides and carries a profile section forming a rack cooperating with a reversible endless screw and which can be locked by a second shoe. The movement of the second shoe is controlled by a lever able to pivot against action of springs via another lever fast with an articulated control bow placed between the two slides so as to free the endless screw placed in a casing and cooperating with the rack for forming a mechanical memory for the slides.

Abstract: An accurizer is provided for improving the accuracy of handguns by eliminating or lessening the potential misalignment of the barrel from which a projectile is fired and the sights used by the operator to aim at the target. There is provided a barrel having a modified area having an outside surface machined down and threaded. There is further provided a bushing having an outside tapered surface and inside threaded surface. A slide is provided having an inside surface tapered to fit the bushing.
Abstract: A waterproof switch includes a switch mechanism having an operation portion, a plurality of leads, each lead having an essentially circular outer periphery, connected to said switch mechanism and a waterproof housing having an external shape which substantially corresponds to that of the switch.
Abstract: A stove top adapter is provided which is constructed so that a collar is provided on the top side thereof whereby a pipe can be received to be vented through a full masonry chimney in order to achieve a direct connection of pipe from the stove through the chimney to the cap on top of the chimney.
Abstract: An application of .alpha.-[[(2-hydroxy-1, 1-dimethyl-ethyl) amine] methyl] enzene methanol hydrochloride (EL-508), as a compound with antiinflammatory action, as well as the different pharmaceutical compositions in which the referred compound is the active principle and its use in therapeutics as an antiinflammatory drug.
Abstract: A method and apparatus is provided for determining decreases and increases of viscosities of used oils or fluids and to detect changes in the oils or fluids during operation in equipment or storage. The limits on both ends can be established by the individual user to meet his or her own specification. Also, the standards can be prepared in a laboratory using various amounts of lesser and higher viscosity oils or fluids to attain the minimum and maximum limits required. There is provided three cups having holes or apertures in the lower end and wherein the holes or apertures are of different sizes, and wherein the cups are adapted to be moved into engagement with containers having oil or fluid therein, and then the cups are raised or immersed to permit the oils or fluids to drain through the holes to accomplish the desired results.
Abstract: A reversible knick knack shelf is provided that can be used for homes and offices and wherein various articles can be held or supported thereon. The shelf assembly and unit can sit on a desk, table, or other flat surface. Different means can be provided for interconnecting the support members together as, for example, hollow tubular members can be provided for interconnecting the shelves or support members.
Abstract: A roofing product is provided that has a release film on the back surface thereof, and the release film is split to allow the material to be flopped back; one side is stuck and then the other side is flopped down. The roofing product includes a top surface having roofing granules thereon and wherein a selvedge is provided along the length of the product for overlapping several of them on the roof. An important aspect of the present invention is that the back surface has a silicone coated 2-section release film. The composition of the roofing product consists of polymer-modified bitumen which makes the product self-adhering. There is a fiberglass reinforcement inside the product.
