Abstract: A ladder having a foot having a plastic body with a recess which receives the end of a first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The base has a front edge. The foot has a metal rail fastener which extends through the body and the rail to attach the body and the rail together. The foot has a pad having a rigid plate with a rubber outer layer surrounding the rigid plate and a pad fastener hole that extends entirely through the rigid plate and rubber outer layer, the outer layer of the pad having a bottom with treads. The foot has a metal pad fastener that extends entirely through the pad and entirely through the base to attach the pad to the base so the rigid plate is between the treads and the base of the shell. A ladder foot. A method.

Abstract: A vehicle propulsion system includes an air heating chamber that receives inlet air from an air intake chamber and provides thrust through an exhaust chamber. A battery powered pulse generator generates a pulsed electrical output signal. An amplifier amplifies the pulsed electrical output signal to provide an amplified pulsed power output signal to the air heating chamber. The amplified pulsed power output signal directly heats the inlet air to generate thrust through the exhaust chamber.

Abstract: An apparatus and method for packing pills in cavities formed in a blister web includes a plurality of downwardly directed flexible members, for example brushes, that are continuously cyclically moved to contact and knock down pills that are not properly nested in respective blister cavities. The flexible members are mounted parallel to and spaced apart from one another.

Abstract: A mouthpiece temperature monitor. The mouthpiece is to be worn by a subject during physical activity. The mouthpiece also houses a temperature sensor for detection of a temperature of the subject.

Abstract: The invention provides a rainwater guttering system comprising plastic trough shaped gutter lengths (1) in which one side wall (2) of each length is extended upwardly and reversed back on itself to form an inverted U-shaped clip (3) which fits over the upper edge (4) of a fascia board (5) which provides a continuous support. Adjacent gutter lengths are directly fixed together and supported at selected spaced points, the arrangement being such that any changes in length dimensions of the system due to temperature changes are accommodated by local buckling of the gutter lengths. Preferably, the system includes a fascia board (5) especially formed to present a continuous free upper edge.

Abstract: A reliable fastener to quickly and easily secure a flat sheet around the mattress of a bed, particularly a water bed, to prevent an inadvertent removal of the sheet from the mattress. First and second complementary pieces of adhesive material are arranged at each of the corners of the sheets and at areas of the bed frame over which the mattress corners are laid. A pocket is associated with each of the sheet corners to enable the user to insert his hand therein and guide a first piece of adhesive at the sheet corner into mating and releasable engagment with a second piece of adhesive at the bed frame.

Abstract: In a drainage inspection chamber of the kind having a manhole access and a base with at least one channel in the base extending between an inlet opening and an outlet opening, the base is formed from plastics material and has an integral side wall structure, circular openings in the side wall structure constituting the inlet and outlet openings. Separately formed socket members for receiving inlet and outlet pipes are located at each of the openings, each of the socket member being provided with a resilient sealing member for sealing with the outer surface of a pipe fitted into the socket member, the sealing member also serving simultaneously to seal the socket member with the internal surface of the inspection chamber.

Abstract: The problem of defaced acoustical ceilings in homes, apartments, offices, etc., is eliminated in a highly simple and economical manner. The ceilings are defaced as the result of the removal of decorative hooks which suspend plants, etc. In accordance with the present method, the unsightly hole and surrounding defaced region are effectively obscured by first removing a circular region of acoustical substance from the underlying wallboard surface, the circular region having as its center the hole formed by the decorative hook. Thereafter, a circular patch of acoustical material is applied to the wallboard surface, completely filling the circular region from which the acoustical material was removed. The result is such that it is difficult to ascertain what part is patched and what part is not.In accordance with the apparatus, a circular patch of acoustical material (or simulated acoustical material) is provided in combination with a tool of corresponding size.

Abstract: Apparatus for diffusing the working medium gases which flow from the compression section of a gas turbine engine is disclosed. A controlled diffuser comprising an inner and an outer flow path shroud initially increases the static pressure and decreases the velocity of the medium gases flowing therebetween. The diffusion process is completed downstream of the flow path shrouds in a dump region of rapidly increasing flow area. The inner and outer shrouds of the controlled diffuser are concentrically supported at both the upstream and downstream ends. The inner and outer shrouds support the compressor exit vanes within the path of working medium gases flowing from the compressor and damp vane vibration during operation of the engine.
