A method and apparatus for serially removing the forwardmost plate from a stack of plates comprises rotating a cylindrical carrier having a chordal segment defined on its periphery with the stack of plates oriented so that the forwardmost plate is tangentially adjacent to the periphery of the carrier. A vacuum source draws air into an air inlet located on the chordal segment thereby creating a low...

A means and method for applying innerliner material to a tire building drum and more particularly to a means and method for cutting and applying the innerliner material and further allowing for stock width measurement and precise centering without the possible edge distortion of known guiding systems.

PURPOSE:To expand remarkably an applicable range of a self-inspecting property inspecting circuit to a non-sequence code output logical circuit, by utilizing a quality owned by a non-sequence code, and deforming a logical function which represents the code in one sense, to a self-inspecting form. CONSTITUTION:A code word of a non-sequence code Y is divided into groups Y<0>, Y<1>, the number of cod...

An arithmetic device having successive arithmetic registers connected in cascade, with buffer registers at each end of the cascade. An information exchange circuit bidirectionally connected to all the arithmetic registers for controlling information transfer therebetween such that the first register is connected to all of the other registers and every other register is also connected to a precedin...

Flashlamps (13 to 17, n), which can be sequentially controlled by a multiplexer (52), are arranged above and/or alongside the track of travel of models (39), to balance a signal evaluation circuit (62), and of test pieces (3), to carry out testing, and put in groups (18, 19, 20) onto different test zones of the continuously moving glass objects. Flashlight reflected from the glass objects is proje...

The invention relates to a process of making articles of foamed polymethyl methacrylate (PMMA). In a first process stage a mixture comprising monomeric methyl methacrylate, plasticizer, preferably liquid foaming agent and catalyst is polymerized by heating and/or irradiation to form a foaming agent-containing solid body. In the second process stage this body is foamed by heating to the softening t...

Entangled nonwoven fabrics are dry print bonded to produce nonwoven fabrics having an excellent combination of strength, softness, and durability.

Silicone elastomeric films of 1 to 500 microns can be made by coating an addition-curable or dehydrocondensation-curable silicone elastomer composition on a coated paper which has a peeling resistance of no more than 50 g/cm, curing the composition, and then peeling the film from the coated paper. These thin silicone elastomeric films can be used for gas separation.

Rubber powders comprising unvulcanized rubber particles with an anti-tack agent covering are disclosed. These powders are made directly from rubber and anti-tack agent mixtures by mechanical action at a temperature above the glass transition temperature of the rubber. Typical rubbers used include NR, SBR, EPDM, BR and blends thereof and typical anti-tack agents include carbon black, silica and the...

A foamable phenolic resole composition is foamed and cured with an acid curing agent which is an anhydrous aryl sulfonic acid which has a pKa of less than about 2.0 and which reduces the compatibility of the resole with water, e.g. benzene, toluene or xylene sulfonic acids. The phenolic foam formed has cell walls which are substantially free of perforations. The preferred anhydrous aryl sulfonic a...

A closed cell phenolic foam having a cell structure in which the cell walls are substantially free of both ruptures and perforations is made by foaming and curing a foamable phenolic resole composition containing an aqueous phenol formaldehyde resole, a surfactant, a blowing agent and optionally other additives, with an acid foaming and curing agent which is an anhydrous aryl sulfonic acid which h...

A foamable and simultaneously curable polyester composition is provided. The composition consists essentially of the following (all being in parts by weight): (a) 100 parts liquid unsaturated polyester resin, (b) 0.5 to 10 parts monosubstituted sulfonyl hydrazide having the formula RSO2NHNH2, wherein R is C1-C12 alkyl, C5-C6 cycloalkyl, C7-C10 aralkyl, phenyl, naphthyl, or phenyl substituted with ...

A process is disclosed for the rapid dissolution of a water soluble polymer by mixing the polymer with water and using a hydrophilic wetting agent, wherein the water is introduced under normal mixing conditions into a prepared water-in-oil polymer dispersion that is free of wetting agent, the wetting agent being added after dilution of the prepared water-in-oil dispersion with water. It is preferr...

The subject invention is a foamable composition based on a blend of a carbon monoxide- or sulfur dioxide-containing ethylene copolymer and a vinyl or vinylidene halide polymer, and the closed-cell foamed article produced therefrom.

In order to improve the accuracy of borehole survey systems utilizing probes with inertial components including inclinometers, two ring laser gyro units are included to provide rotation information 56, 58 to the system. When the probe is moving in a borehole, inclinometer information 50, 52, 54 is used 78 to produce a synthetic rotation signal 80 to take the place of a third gyro and the earth's r...

A machine for de-charring the inside of a used whisky cask (51) comprises a pair of chuck rings (4, 5) for gripping and rotating the cask about its axis while a counter-rotating flapper-type grinding wheel (43) is moved by a longitudinal feed carriage into the cask from one end in a direction which is slightly skew to the cask axis.
