Abstract: A placard holder device that removeably holds for display an informational placard that can be viewed through the windshield of a parked vehicle, and which enables simple and quick manual repositioning into a stored position that does not obstruct the line of sight through the windshield. Only a single action step is needed to make the placard visible or invisible. The device features: a frame that removeably holds the placard for display, a mounting body having a hinged connection to the frame, a clasp distal to the hinged connection for releasably clasping the frame to the body, and a clip for removable attachment to a visor of the vehicle. Examples of informational placards include: handicapped or parking passes; identifications of a parked vehicle of a member of the media/press, or of a delivery service; placards that display information about a vehicle at a car show or dealership.

Abstract: A fluid piston engine with a plurality of cylinders wherein the plurality of cylinders are daisy chained through a single turbine having a single impeller. The fluid piston engine has a plurality of daisy chained cylinders that burn a fuel of hydrogen, and an oxidizer of air, preferably oxygen. A method of operating a fluid piston engine with a plurality of daisy chained cylinders includes steps where the operating controls are triggered by a fluid level sensor in a cylinder. Rather than from the cylinder, combustion byproducts are exhausted through a relief valve on an accumulator. Engine performance is varied by selectively idling cylinders and by varying the relative timing of multiple pairs of cylinders, wherein each pair uses internal combustion to expel fluid out of a first cylinder, through the turbine and into the second cylinder of the pair in which the combustion gases are compressed by the circulating fluid piston.

Abstract: Manufacturing equipment and manufacturing process steps that improve upon prior art processes for the manufacturing of filament tube and arc tube light sources, their components and subassemblies, and lamps employing said light sources. A double ended, tipless filament tube or arc tube light source incorporates a drawn-down tubular body, and one piece foliated leads with spurs for process handling and for spudding into a filament with stretched-out legs. Bugled ends on the body provide a novel cutoff means, facilitate a flush-fill finishing process, and enhance mounting and support of the light sources in lamps. The foliated leads are made from a continuous length of wire in a process including foil hammering and two-bath AC electrochemical etching. Cost-reduced light source and lamp production enables affordable household consumer lamps, even when containing two series-connected halogen filament tubes.

Abstract: The present invention features an airbag to be worn by swimmers for safety. The airbag device generally relates to personal floatation in the water and more particularly comprises, a plastic inflatable airbag, an air filling tube for filling or draining air, and an air check valve. The airbag is inflated by the wearer's breath, or in an alternate embodiment, an electrical air pump or compressed gas cartridge or gas generated by a chemical reaction. The airbag is worn around the lower abdomen (for the male wearer) or placed on the ribs or breast (for the female wearer). The airbag is worn underneath the swimming apparel and is practically invisible to an onlooker. The airbag can be made in smaller sizes to be worn in other parts of the swimmer's body (such as the neck) along with the main airbag for enhancing buoyancy. When the swimmer is not inside the water, the inventive safety airbag can be comfortably deflated allowing the wearer to perform other tasks such as walking or eating, with ease.

Abstract: A prefabricated barrier for providing protection to subterranean walls and other structural members against both penetration by water and by termites, are disclosed. The barrier has a tacky and waterproof compound, preferably an asphaltic compound, protected by a release liner which is peeled from the web immediately prior to installing the web on building surfaces. A layer of stainless steel mesh is used to inhibit passage of termites. The invention comprises a protective release liner, a first layer of tacky compound, a fiber reinforced material (preferably fiberglass), a second layer of tacky compound, a stainless steel mesh, and a layer of protective film.
