Abstract: A hydroxy functional epoxy-polyester graft copolymer and solvent-based thermosetting coating composition comprising said copolymer and blocked polyisocyanate crosslinking agent. The coating composition may be formulated as hot sprayable, high solids coating composition suitable for use as chip resistant automotive vehicle primer adapted for use on body panel areas subject to chipping by stones, gravel and other road debris. Alternatively, the composition may be formulated as a high solids composition sprayable with conventional spraying equipment. The hydroxy functional epoxy-polyester graft copolymer is the product of polymerization of certain lactone monomers in the presence of hydroxy functional epoxy ester resin precursor. The precursor resin is the reaction product of diepoxide with aliphatic diol and, subsequently, with acid component comprising primary hydroxy functional acid. The polymerization of the lactone monomers is carried out at a temperature between about 50.degree. C. and about 300.degree. C.

Abstract: A header apparatus for a flat IC pack having at least one conductive terminal includes a header housing which includes an IC pack chamber, an opening communicating with the IC pack chamber, the IC pack being inserted into and extracted from the opening, and a pair of actuation means, each of which includes drive member having a first surface formed inside the IC pack chamber of the header housing and a first rack, operation member which includes a second rack positioned to face the first rack of the drive means and an operation portion formed outside the IC pack chamber, and a pinion engaged with the first and second racks, wherein the first surface of the drive member is moved in an insertion direction of the IC pack by inserting the IC pack into the IC pack chamber, and pushes the IC pack inserted into the IC pack chamber in a direction opposite to the insertion direction of the IC pack by moving the operation portion of the operation means in the insertion direction of the IC pack.

Abstract: A device for controlling the rectilinear translation of a movable member, comprises a screw engaged by a nut having cooperatingly shaped thread surfaces the dimensions of which are such that there is a radial clearance between the screw and the nut and an axial clearance between adjacent helical flanks of the screw and the nut. The nut is provided with radial passages communicating with the chambers defining the radial clearances, which can be put into communication with a source of compressed gas enabling the formation of an air cushion or air bearing between the two relatively movable members thereby reducing the turning moment necessary for effecting rectilinear movement of the movable member.

Abstract: N-(heterocyclicaminocarbonyl)pyridinesulfonamides; are useful for the regulation of plant growth and as pre-emergence and post-emergence herbicides.

Abstract: A connector is formed as a molded body having a sub-assembly that includes a terminal board aligned transverse to the longitudinal axis of the cable and an attached receptacle strip that includes an array of pin-receiving receptacles. The receptacles are secured at one end to the terminal board which also includes printed circuit wiring traces to facilitate electrical connection between the receptacles and the wire conductors of a ribbon cable. A frame is provided within the molded body and includes a base having an elongated slot formed therein and upstanding tabs at the opposite ends. The sub-assembly is positioned relative the slot so that the receptacle strip and its pin receptacles are in substantial registration with the slot. The frame and the terminal strip, as well as the end portion of the ribbon cable, are maintained in their assembled relationship by the molded body. The tabs each includes apertures for engaging a connector removing tool.

Abstract: Antibacterial activity is exhibited by 3-acylamino-2-oxoazetidines having in the 1-position an activating group of the formula ##STR1## wherein R is ##STR2## and R.sub.

Abstract: In a process for the oxidative dyeing of human or animal hair, a hair dyeing agent is prepared immediately before use from at least one oxidation dye and an oxidizing agent, applied to the hair to be dyed, and made to act for a given period of time, whereupon the hair dyeing agent is washed out. The hair dyeing agent that is to be used is prepared from an oxidation dye and the oxidizing agent with the concomitant use of manganese dioxide in powder form, while the finished hair dyeing agent is adjusted to a weakly acid pH in the range from 5.9 to 6.9.

Abstract: The invention relates to a method of making flange half shells and flanges made therefrom, whereby an optimum arrangement of the flanges should be obtained with respect to their use, for this purpose the flange half shells (1) are held together by means of clamps (2), whereby the clamps (2) engage into associated suitable slots (3) which are provided in the flange half shells (1). Furthermore, the flange half shells are extruded from a strand and therefore obtain a hardness which is adapted to the hardness of the mounting screws.

Abstract: The invention relates to plasma arc apparatus.

Abstract: A foldable mirror structure for providing self-observation reflective images from any desired position about a user. The mirror structure includes a main frame with a primary reflector mounted centrally thereon for pivotable movement between forwardly facing, right angular facing and left angular facing attitudes. Right and left hand secondary reflectors are coupled to the opposite sides of the frame by coupling frames and are pivotably movable between folded and extended positions.

Abstract: An alcohol free wine beverage is produced by diluting a table wine with demineralized water and feeding the diluted wine to a centrifugal film evaporator where alcohol is stripped from the wine to produce an alcohol free wine base. The wine base is then mixed with grape juice concentrate to produce a finished alcohol free wine. Other ingredients may be added to the wine base such as carbon dioxide, citrus juice and preservatives, and additional demineralized water may be added to further lower the alcohol content prior to bottling.

Abstract: Cationic polyvinyl alcohol is prepared by blending polyvinyl alcohol under high shear conditions, at 0.degree.-100.degree. C., with a small amount of water, a small excess of base, and a quaternizing agent containing a halohydrin radical and a quaternary ammonium group. The quaternization proceeds with acceptable conversions of about 35 to well over 50%. The quaternized polyvinyl alcohol has many applications, including use as a flocculating agent, as a stabilizing colloid, and in adhesive formulations.
