Abstract: This invention relates to a sealed solder wire connector assembly and method of use operable to connect to an electrical wire member. The sealed solder wire connector assembly includes 1) an electrical terminal member having a solder connector end section on one end of a main terminal body; and 2) a protective sleeve asesmbly mounted about the electrical terminal member and constructed of a heat shrink material with an adhesive coating on an inner surface thereof. The solder connector end section is of a semi-circular shape with a low temperature melt solder coating to receive the wire member thereagainst. Application of heat to the sealed solder connector assembly results in 1) melting of the solder coating into the wire member; 2) melting of the adhesive coating; 3) shrinking of the protective sleeve assembly about the wire member and the electrical terminal member; and 4) removing the heat to achieve an air tight fluid sealed solder wire connector assembly.

Abstract: A high solids content, aqueous, microcapsule-containing printing ink is prepared by forming microcapsules in situ in a printing ink vehicle. The microcapsules are preferably prepared by interfacial polymerization or interfacial crosslinking between a reactant, such as a polyisocyanate dissolved in an oily solution and a coreactant such as a polysalt of casein and diethylene triamine present in an aqueous solution into which the oily solution is dispensed. The aqueous solution contains water and a non-volatile diluent such as a non-reducing sugar, for example methyl glucoside. The printing ink preferably has a 60-70% by weight solids content and may be used as a low-coat-weight CB coating for preparing carbonless copy paper.

Abstract: A curved-mold continuous casting apparatus has a reciprocable mold with a curved casting passage and an arm which guides the mold for reciprocation. A secondary cooling unit is located downstream of the mold and is followed by a withdrawal-and-straightening unit. The apparatus further has a rigid, curved dummy bar, a piston-and-cylinder unit for moving the dummy bar between a storage position and a casting position, and a lever which is articulated to the dummy bar and guides the same. A support consisting of a bedplate with an upright stand holds the mold, guide arm, secondary cooling unit, withdrawal-and-straightening unit, dummy bar, piston-and-cylinder unit and lever in assembled condition and in alignment for casting. The support and the components carried thereby form a preassembled, transportable module which can be brought to a casting location or removed from such location.

Abstract: A mold for making bathtubes is disclosed. The mold includes a mold receptor and an insert attached to the mold receptor face. The mold receptor receives a shell which has a finish side and a non-finish side. The shell is placed in the mold receptor leaving a void between the non-finish side of the shell and the face of the receptor. The insert is attached to the face of the mold receptor to reduce the cross-sectional area of a portion of the space between the shell and mold receptor face. A male mold engages the finish side of the shell, sealably retaining the shell to the mold receptor. A polymeric foam material is introduced into the void between the receptor and the shell. The polymeric material fills the void and coats the shell. The molded bathtub is then removed from the mold receptor after the male mold has been removed. The insert is then removed leaving an area of reduced thickness and a periphery on the non-finish side of the molded bathtub which defines a lip.

Abstract: In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating concurrently about parallel, non-concentric axes to produce a relative orbital motion, a scroll member including an annular biasing chamber formed in one scroll member end plate opposite the scroll wrap and a passage from one of the chambers formed by the scroll wraps for providing fluid to the chamber. The fluid exerts a force upon a pressure plate secured to the opposing scroll end plate and thereby acts to bias the scroll wraps into contact with the opposing scroll end plate. Seals are provided in the biasing chamber of the scroll end plate to ensure contact with the pressure plate of the opposing scroll member.

Abstract: Microwave landing systems are used to enable aircraft to make landings even in poor visibility. One distinguishes three categories of approach and landing manoeuvers. Of particular importance are Category III operations, i.e., those in which the pilot depends exclusively on the navigation system, because he cannot see the runway. Throughout a Category III landing operation, it must be ensured that the navigation system does not fail, and that the information contained in the signals being radiated by the navigation system is reliable. To that end, two executive monitors are arranged such that the first to detect a signal error functions as a master monitor. If the slave monitor then detects (within a reduced error threshold) the same signal error, an error in the system being monitored is confirmed and appropriate safety measures are taken (e.g. immediate changeover from the faulty transmitter).

Abstract: A sensor and method for measuring the concentration of alcohol in an alcohol-hydrocarbon mixture for use with flexible fuel vehicles. The sensor and method are characterized by a pair of detectors or sensing elements which detect absorbance of two different wavelength bands of energy transmitted through the fuel. The first wavelength band is absorbed by the alcohol and substantially unabsorbed by the hydrocarbons and other non-alcohols in the fuel mixture. The second or reference wavelength band is selected where the absorbance of alcohols and hydrocarbons is essentially the same and preferably essentially zero. The output of the two detectors or sensing elements is ratioed to provide a signal representative of the alcohol content of the fuel mixture. In a preferred embodiment, the sensing elements are included in a differential thermopile.

Abstract: A fluid bed catalyst which has lost activity or fluidization quality through agglomeration, contamination, or a physical or chemical change on the surface of the catalyst is deagglomerated and/or its surface re-exposed, by contacting the fluidized catalyst with a high velocity gas sufficient to cause multiple collisions among the catalyst particles and thereby deagglomerating the particles and/or abrading the surface of the particles to expose fresh catalyst.

Abstract: A process for spectroscopically measuring the content of a component in a liquid mixture involves passing a single optical beam through the mixture without the use of a reference beam and measuring the intensities of transmitted light in two different wavelength bands by means of two adjacent detectors responsive to light in the two wavelength bands respectively. The component being measured absorbs light within one of the wavelength bands. The ratio of the detector outputs can then be related to the component concentration. The principal use of the invention is for in-situ measurement of methanol in gasoline for motor vehicles.
