Abstract: A device lot terminating a roof surface at a vertical edge In a waterproof and airtight manner may serve as a flashing strip at a parapet wall, a wall cap, a roof edge, an expansion joint or in other roofing applications. The device comprises a relatively rigid member, typically of sheet metal or the like, and a flexible member, typically of modified coal tar bitumen, EPDM, or other suitable roofing material. The device has a channel formed in the rigid member along a longitudinal edge that receives the flexible member in an airtight and watertight manner. In this configuration, the flexible member provides a covering for the fastening surface on the rigid member, which is fastened by conventional means to the roofing surface and the underlying support structure. The preferred channel is formed from a pair of longitudinal bends made in opposite directions such that a "Z" shape cross section is formed.

Abstract: An apparatus and method for pressurizing liquid contained within a single, food-grade container or a series of such containers from an external source of gas, and for drafting liquid from the container (s). CO.sub.2 may be used to carbonate liquids such as beer or soft drinks, or alternatively air or inert gases may be used in conjunction with non-carbonated liquids such as wine.According to a preferred embodiment the disclosed apparatus, which may be used with a single container or each one of a series of containers, comprises a cap screwed onto the container neck and a nipple assembly attached to the neck via the cap. The nipple assembly includes a body section and a plurality of nipples attached thereto. Each nipple has an outer portion protruding externally of the container, an inner portion disposed within the container and an interior flow passage extending through both portions. An annular seal is disposed so as to prevent fluid leakage between the body section and the container neck.

Abstract: A probe system for monitoring chemical activity of a target chemical in an environment has first and second marker compounds each bonded to a common substrate to keep the respective markers in physical proximity. The first marker is a chemical that has a maximum emission intensity at a first wavelength, and it is chemically shielded from the environment being studied. The second marker is a chemical that, when in a first state, has a maximum emission intensity at a second wavelength different from the first wavelength and which, in a second state, does not have a maximum emission intensity at the second wavelength. The second marker is convertible between said states through chemical reaction with the target chemical. The common substrate is a carrier particle, the first marker being impregnated within the carrier particle and the second marker being chemically bonded to the exterior surface of the carrier particle.

Abstract: A class of soluble polymers having a rigid rod backbone, which when used to cast films, undergo a self-orientation process whereby the polymer backbone becomes more or less aligned parallel to the film surface. This in-plane orientation results in a film that displays negative birefringence. The degree of in-plane orientation and thus, the magnitude of the negative birefringence is controlled by varying the backbone linearity and rigidity of the class of polymers which includes polyesters, polyamides, poly(amide-imides) and poly(ester-imides) through selection of substituents in the polymer backbone chain. By increasing the polymer backbone linearity and rigidity, the degree of in-plane orientation and associated negative birefringence can be increased, and that conversely, by decreasing the polymer backbone linearity and rigidity, the negative birefringence can be decreased.

Abstract: An imaging table for medical examination and imaging procedures. A tilting imaging table comprises a rectangular base frame on wheels, a column extending upwardly from the base, and a tilt assembly which includes a pair of rotatable pivot arms at the top of the column. A radiolucent table top for imaging purposes is removably secured to the tilt assembly. At least two interchangeable radiolucent table tops, of different configurations and used for different medical imaging purposes, accompany the tilting imaging table and may be secured removably, one at a time, to the tilt assembly. This tilt assembly and any table mounted thereon are tiltable about a transverse axis between a head up position (e.g, 30.degree. head up) and a head down position (e.g., 30.degree. head down). Greater degree of tilt in one direction can be provided if desired. Also shown is a limit stop mechanism for retaining a tilting assembly including pivot arms in a horizontal position.

Abstract: A safety device replaces the cover plate of a wall-mounted electrical outlet box having a pair of female receptacles for receiving a male plug. The safety device has a face plate, a back plate, a pair of shutters and a biasing means. The face plate has a front face and an opposing back face. The face plate has two large apertures in it, corresponding to the two female receptacles and exposing the receptacles when the face plate is positioned atop the outlet box and secured to it. The back plate has a inner surface and an outer surface and an aperture, which is shaped and positioned to correspond to the pair of female receptacles. When the front plate and back plate are mated, the front plate and the back plate are joined with the back face of the front plate, the inner surface of the back plate and a pair of parallel flanges on the back face defining a channel. First and second shutters, corresponding to each of the large apertures on the face plate, cover the apertures.

Abstract: A method and device for controlling a motor in a powered seat, wherein, in an automatic control mode, a rated voltage is applied to the motor, thereby causing a constant high rotation of the motor, and in a manual control mode, firstly the rated voltage is applied to the motor and secondly after a given time, the voltage is changed into a low voltage, causing the motor to be driven at a low rotation rate. Thus, the movable parts of seating posture adjustment device in the seat are moved rapidly in the automatic mode, while in the manual mode, they are firstly moved rapidly and then slowly for permitting an accurate adjustment of position thereof.

Abstract: Self-reinforced polymer composities of 60-5 percent by weight of an at least partially crystalline high performance thermoplastic polymer and 40-95 percent by weight of a melt processable wholly aromatic polyester which exhibit anisotropic properties in the melt phase. This wholly aromatic polyester is a liquid crystal polymer, or LCP. The high performance themoplastic polymer has a melting point of at least 200.degree.. Polyether etherketone is a preferred at least partially crystalline polymer. The wholly aromatic polyester is in the form of predominantly unidirectionally oriented continuous fibers primarily in the range of about 1 to 10 micrometers in diameter, distributed in a matrix of polyether etherketone. The polymer composites of this invnetion have high tensile strength, high modulus, satisfactory elongation, good impact strength, and good high temperature properties.

Abstract: A portable detection system, including a receiver tuned to the frequency of signals transmitted by an aircraft transponder, will detect the presence of an aircraft in proximity to the system. The system has signal processing circuitry to transform the received signals to indicate the altitude of the detected aircraft. A display or alarm may alert the user to the presence of an aircraft. The system is useful to determine whether an aircraft may be engaged in a speed detection and ticketing operation or the closeness of other aircraft. The aircraft detection system may be used in conjunction with a radar detection system to provide a means by which various methods of traffic control can be detected.
