Abstract: A clamping ring for use in pipe joints has an inside surface which is formed with generally peripherally extending indentations for axially fixing a pipe. In order to prevent an occurrence of dangerous stress concentrations in pipes in contact with such clamping rings and to permit such rings to be manufactured economically, the clamping ring is formed on its inside surface with a multiplicity of generally peripherally extending indentations, each of which extends only along part of the periphery of said inside surface, and said indentations are offset from each other in said peripheral directions and adjoint or overlap.
Abstract: Electrostatic liquid developer consisting essentially of(A) nonpolar liquid having Kauri-butanol value less than 30, present in major amount,(B) thermoplastic resin particles having a metallic soap as defined dispersed therein and average particle size by area being less than 10 .mu.m, and(C) nonpolar liquid soluble ionic or zwitterionic charge director compound. Optionally a colorant and charge adjuvant are present. The electrostatic liquid developer is useful in copying, making proofs including digital color proofs, lithographic printing plates, and resists.
Abstract: A drill bit assembly comprised of a pilot bit and a plurality of add-on reamer sections which are sized to progressively increase the diameter of the hole in measured increments. Both the pilot bit and the reamer sections have two cutter elements which take advantage of the bi-center concept and both use knife edged cutters instead of teeth to drill the hole.
Abstract: Water-dispersible synthetic fiber of scalloped-oval cross-section to promote dispersibility, and so better uniformity, softer feel and more opacity to the resulting wet-laid fabrics.
Abstract: The invention is directed primarily to a method of doping tin oxide with Ta.sub.2 O.sub.5 and/or Nb.sub.2 O.sub.5 using pyrochlore-related compounds derived from the system SnO--SnO.sub.2 --Ta.sub.2 O.sub.5 --Nb.sub.2 O.sub.5 for use in thick film resistor compositions. The invention is also directed to thick film resistors containing the above-described pyrochlore-related compounds and to various compositions and methods for making such thick film resistors.
Abstract: 7-Oxabicyclo(2.2.1)heptane analogs are disclosed having the general formula ##STR1## wherein R.sub.1 is lower alkyl, alkenyl, substituted alkenyl or alkynyl; R.sub.2 is lower alkyl, alkenyl or alkynyl; A is --CH.sub.2 --CH.dbd.CH-- or a single bond; X is --CH.sub.2, --CH(CH.sub.3) or --C(CH.sub.3).sub.2 ; n is an integer from 0 to 9, with the proviso that when A is a single bond, n is an integer from 1 to 9; including all stereoisomers.These new compounds have been found to be inhibitors of arachidonic acid cyclooxygenase and are therefore useful as antiinflammatory antipyretic and analgesic agents.

Abstract: Herbicidally active pyridinesulfonamide compounds having an ortho cyclic saturated or partially saturated group which includes a carbonyl or sulfonyl radical display utility as herbicides and plant growth regulants.
Abstract: An improved caster construction wherein a brake is provided for selectively braking both the wheel against rotation and the yoke against rotation around the axis of the post of the caster. The post includes a lower end having a nut fixed thereto and the brake includes a brake plate having a socket for selectively engaging the nut to prevent rotation of the yoke about the axis of the post.
Abstract: This invention relates to unique stable support structures comprising substrates coated with sterically-protecting monofunctional silanes. This structure consists of an appropriate reactive solid to which a monofunctional silane is covalently bonded that contains at least two sterically-protecting groups attached to the silicon atom of the silane.
Abstract: Process for production of dinitriles using zero-valent nickel catalysts having low ligand ratio, and low amounts of zinc halide as the promoter.
Abstract: A coated web drive uses a cluster of support and blotting rollers, the latter being switch to contact the web and dry wet portions of the web which typically occur at splices.
Abstract: The improvements relating to capacitive devices for measuring the diameter of a dielectric fiber are based on a particular shaping of the capacitor plates, such as to allow electric field reductions at the edges to be compensated for and hence capacitance measurements to be unaffected by fibre vibrations.

Abstract: Novel aminomethyl oxooxazolidinyl benzene derivatives, including the sulfides, sulfoxides, sulfones and sulfonamides, such as (l)-N-[3-[4-(methylsulfinyl)phenyl]-2-oxooxazolidin-5-ylmethyl]acetamide, possess useful antibacterial activity.
Abstract: A continuous multifilament crimped polyamide or polypropylene yarn suitable for use in loop pile carpeting and the process for making the yarn including feeding the yarn at different tensions and then treating the yarn with saturated steam is disclosed.
Abstract: This invention relates to novel pyrazolesulfonamides, agricultural compositions thereof and the methods of their use as general and/or selective herbicides and/or plant growth regulants.
Abstract: A zero insertion force connector for a printed circuit card. The connector has opposed rows of terminals having normally spaced contacts at the ends of outwardly bowed portions. Cams and followers are located beneath the bowed portions in positions where the followers can engage the bowed portions, engage the contacts with an inserted card and then stress the bowed portions, supplying contact normal force and contact wipe.
Abstract: Calender roll comprising a cylindrical metal shaft bearing a polyimide cover, wherein the shaft is knurled to eliminate slippage between the shaft and the cover.
Abstract: This invention relates to novel herbicidally active sulfonylurea compounds substituted in the positions ortho to the sulfonylurea bridge, agriculturally suitable compositions thereof and methods of their use as preemergent or postemergent herbicides or plant growth regulants.
Abstract: A highly permeable aromatic polyimide gas separation membrane and the process of using it are disclosed. The aromatic polyimide has the formula ##STR1## wherein --Ar-- is ##STR2## or mixtures thereof, --X, --X.sub.1, --X.sub.2 and --X.sub.3 independently are alkyl groups having 1 to 6 carbon atoms or aromatic groups having 6 to 13 carbon atoms, and --Z is --H, --X, --X.sub.1, --X.sub.2, or --X.sub.3 ; and R is ##STR3## or mixtures thereof.
