Abstract: An electrical connector is disclosed for electrically connecting a pair of spaced apart conductive pin members. More particularly, an electrical connector is disclosed comprising an elongated housing having opposed cover members and further including an elongated actuator member extending therebetween. A continuous, electrically conductive contact member is provided which is resilient and has a dumbbell-shaped configuration. The contact member is disposed about the actuator member in a loose fit relationship. During mounting of the connector, the actuator member effects an elongation of the contact member to reduce mounting forces. The unique configuration of the contact member enables a redundant electrical connection to be established between the pins and the contact member. In a preferred embodiment of the subject invention, the connector housing is rectangular having opposed pairs of side walls.

Abstract: A cutting insert for use with an indexable cutting tool is formed from a flat wafer of cutting material which is generally polygonal in plane form and includes a pair of opposed faces and a plurality of upstanding side walls extending therebetween. The juncture of the side walls with each face defines the cutting edges of the insert. The polygonal insert which includes a plurality or radiused corner portions, is provided with at least one nonplanar insert face wherein the corner portions thereof slope inwardly towards the opposed face of the insert. Each corner portion further includes a pair of generally triangular chip grooves separated by a raised central triangular land area. Each chip groove is spaced from the peripheral cutting edge of the insert to define side land areas which increase in width from the corner portion to their opposed ends. The chip grooves increase in both width and depth from the corner portions to their opposed ends.

Abstract: A single package, air dry waterborne primer system which contains limited amounts of trace elements and offers corrosion resistance.

Abstract: An interconnected assembly of an array of high frequency coaxial connectors includes a pair of mounting plates having opposed mating coaxial electrical connectors mounted therein. The opposed connectors are configured such that a redundant or dual electrical connection is established when one connector is telescopingly received within the other connector. The redundant connection includes a butted interface, as well as a frictional interfit between the connectors. This arrangement eliminates the need to provide individual coupling nuts for securing the link between mated pairs of connectors which enables the distance between connectors along each plate to be reduced thereby conserving space. Further, due to the redundant electrical connection, should vibration or misalignment cause the mated connectors to separate, thereby breaking the butt interface connection, electrical continuity is still maintained.

Abstract: High impact, high modulus thermoplastic molding compositions comprise(a) an aromatic carbonate polymer;(b) a fibrous reinforcing agent essentially free of any sizing agent; and(c) a small amount of a polysiloxane having a substantial content of Si-H bonds.

Abstract: Novel copolymers are prepared by the interaction of low or high molecular weight polyarylates, such as bisphenol A-isophthalate-terephthalate polyarylates, or bisphenol A-isophthalate-terephthalate-carbonate polyarylates and a high molecular weight diprimary dialcohol polyester polymer, such as polyethylene terephthalate polymer. The resulting copolymers are transparent and tough. They maintain their dimensional stability over a wide range of temperature from 75.degree.-175.degree. C., are soluble in chlorinated solvents, and have one glass transition point.

Abstract: Reactions involving diprimary amines, e.g., methylenedianiline, particularly those forming polyesterimides are carried out using, in place of the diamine, a urethane compound capable of yielding the diamine at reaction temperatures. The preparation of wire enamels from polyesterimides thus prepared is particularly described.

Abstract: Dye sensitized epoxy resins containing an iodonium salt cationic photoinitiator can be used in a variety of adhesive bonding applications. Using low intensity visible light, cure can be initiated after a short exposure of resin coated surfaces followed by clamping the subject pieces together for a time sufficient for a permanent bond to form.

Abstract: Apparatus for quenching and cooling the reactor effluent in a thermal regenerative cracking (TRC) system. The quench apparatus includes a section for introducing relatively cool particulate solids into a hot effluent stream to effect initial quenching and a section to further cool the composite of quenched effluent and solids.

Abstract: Cured polyester compositions and their production are described. These are produced by curing a composition containing polyester resin and aliphatic polyol having a molecular weight of at least about 2000. The polyol acts to reduce normal polyester shrinkage incident to curing so as to produce improved articles.

Abstract: Novel high molecular weight resins, useful for electrically insulating conductors, are prepared by polycondensing a mixture of anhydrides, and a diisocyanate and/or a diamine in an inert organic solvent, preferably in the presence of a catalytic amount of 2-methylimidazole.

Abstract: An instrument composed of a measurement head (1) and a fixed stop (2) which are connected by a body (3) formed of interchangeable extension pieces (4, 5), the instrument being intended to check the dimensions of bulky parts.The two contact stops (12) of this instrument are offset at the end of two parallel measurement feelers (10, 11).With each of these two contact members there is associated an instrument for measuring their inclination, which consists of an electronic clinometer (25, 26).The two clinometers are connected to an apparatus (30) for reading the inclination of the two measurement feelers.The inclination of one of the two measurement feelers (11) is adjustable by means of an operating screw (17).In this way it is possible to reestablish parallelism of the measurement feelers when the instrument bends, upon measurements of large dimensions.

Abstract: A personal data bank system is disclosed for use in combination with a digital watch. The personal data bank system is capable of generating, storing and recalling alphanumeric data using a minimum number of switches. The system includes a set control logic circuit capable of generating a sequence of alphanumeric characters which are displayed on the watch. Upon repeated actuations of a single switch, a desired array of characters are selected and thereafter are stored in a memory. Recalling the information is accomplished by either an alphabetic search or by a unique code number system wherein a code number is assigned to each data set. The sequence of characters is generated by the set control logic circuit which includes a blank character to facilitate the programming of the memory.

Abstract: Apparatus and process for quenching and cooling reactor effluent. The apparatus includes a section for introducing relatively cool particulate solids into a hot effluent stream to effect initial quenching and a section to further cool the composite quenched effluent and solids. The process employs relatively cool particulate solids to quench hot effluent and indirect heat exchange between water and the quenched effluent-solids mix to generate high pressure steam and further cool the mix.
