Abstract: A process for preparing 2-chloroterephthaloyl chloride which comprises reacting terephthaloyl chloride with chlorine in the presence of an anhydrous ring chlorination catalyst. When the reaction mixture contains the desired amount of the monochloro product, the mixture is cooled to room temperature and the 2-chloroterephthaloyl chloride is isolated.

Abstract: Integral solenoid and starter motor having four or more poles for internal combustion engines has an electrically conductive disc carried by the armature or core of the solenoid for movement in response to energization and de-energization of the solenoid coil. Three stationary contacts of electrically conductive material are disposed in circumferentially spaced relation about the longitudinal axis of the core for sequential engagement by the movable disc. One of the stationary contacts, connected to an electrical energy source, is disposed at a position closer to the movable disc than the other stationary contacts. The other stationary contacts are connected in parallel circuits to two poles of the starter motor whereby each contact carries one-half the current supplied by the energy source. The disc is tiltably mounted on the core for making initial contact with the first stationary contact and later, with the two other contacts in response to the solenoid being energized.

Abstract: A method of manufacturing a bag for containing liquid, the bag provided with an outlet tube. The method entails seam welding the outlet tube between two superposed bag walls, placing the bag and tube combination between the blocks of a mold, each block having confronting recesses of a particular shape and then injecting molding plastic material to fill these recesses. The injected material forms a collar which completely surrounds the tube and adjacent bag material. The bag film material on either side of the tube is melted to itself and to the tube wall and the collar is thereby securely attached in an encircling configuration thereby to preclude leakage. The tube may be a part of tap or other outlet fitting such as a push pull tap.

Abstract: Ceramic fibers of alumina modified with zirconia or hafnia derived from soluble salts of the metal are made by first polymerizing a mixture of alumina and aqueous aluminum chlorohydroxide before addition of the metal oxide precursor. Subsequent concentration and spinning steps are carried out at low temperatures.

Component (D) can be present in liquid (A) or dispersed in the resin particles. The process of preparation of the electrostatic liquid developer is described. The liquid developers are useful in copying, color proofing including digital color proofing, lithographic printing plates and resists.

Abstract: A single null miniature direction finder which may be worn on the arm of the user and is fully automatic in operation. Signals from a single loop antenna and a sense antenna are summed; however, the amplitude of the sense signal is adjusted at first and second phase angles and the phase of the sense antenna is automatically switched from the first phase angle to the second phase angle prior to summing to produce either a single null or a no null pattern. These patterns are compared to each other as the user extends his arm horizontally and rotates his body. When the null occurs an indicator gives the relative direction to the transmitter.

Abstract: Staple fibers having a crimp frequency in the range of 3 to 6 crimps per centimeter are made by a process including a co-crimping step in which conductive and nonconductive filaments are crimped together.

Abstract: A process for forming a composite that is useful as an exterior vehicle part in which a layer of a coating composition is applied to a flexible smooth glossy polymeric carrier sheet and dried and laminated under heat and pressure to a flexible polymeric substrate to form a laminate, the carrier sheet is removed and the laminate is thermoformed into a three dimensional structure and a rigid thermoformable plastic is adhered to the thermoformed laminate to form the composite; the coating compsition used in the process that forms the exterior finish on the composite has a film forming binder which is in an organic liquid carrier is of a polyesterurethane and a multifunctional crosslinking agent of an epoxy compound or an organic polyisocyanate; whereinthe polyesterurethane is formed by reacting a hydroxy functional polyester with a hydroxy containing carboxylic acid and an organic polyisocyanate.

Abstract: A process for making oriented, shaped articles of lyotropic polysaccharide/thermally-consolidatable polymer blends by orienting spinnable dopes containing fiber-forming polymers being at least about 55% and less than about 80% lyotropic polysaccharide and at least about 20 percent and less than about 45% thermally-consolidatable polymer and removing the solvent.

Abstract: A sliding bearing of the type comprising a backing layer; an intermediate layer provided with internal peripheral grooved portions crosswise the bearing length and longitudinally spaced from each other; optionally, a diffusion or bonding layer on the grooved portions; and a sliding layer of a material softer than the material of the intermediate layer and filling the grooved portions. According to the invention, the grooves of the grooved portions have a depth and longitudinal spacing with uniform or variable dimensions, wherein at least one of the characteristics of depth and spacing is mandatorily variable. This design allows a selective distribution of harder material and softer material on defined portions of the bearing as a function of specific operating requirements.

Abstract: A boat hitch for latching or hitching the bow of a boat to a boat trailer to provide efficient and safe withdrawal of a boat from the water and hitching the boat to the trailer to enhance the safety factor in towing a boat and trailer over the highway. The boat hitch includes a pivotal latch structure mounted on the forward end portion of a boat trailer which is associated with a cam-type keeper on the bow of the boat in which the keeper includes a curved cam ramp extending from a shallow forward end to a rearward end having greater depth and a keeper surface generally extending vertically at the rearward end of the cam ramp. The latch includes a pivotal pawl that is locked in a vertical position in engagement with the keeper surface when the boat is locked on the trailer with the pawl being manually released and pivoted to a generally rearwardly extending horizontal position for releasing the boat to enable it to move off the trailer when launching the boat into a body of water.

Abstract: NO.sub.x and SO.sub.x molecules are separated from a combustion exhaust gas stream by directing the exhaust gases through an elongated passageway, establishing a logarithmic potential across that passageway which will cause separation of the NO.sub.x and SO.sub.x molecules from the exhaust gases based on their permanent dipole moments, the potential being established between spaced conductors and at a relatively low voltage level sufficient to generate a capacitance between the conductors sufficient to cause separation of the molecules from the exhaust gas stream for recovery in a separate chamber.
