Abstract: Abstract of the Disclosure A cross support assembly is provided which is useful, for example, in earthworking equipment.  Such an assembly can be mounted to extend between two lateral supports.  A bracket extends laterally from the assembly and can serve as a supportive pivot for a bucket or the like. The assembly is generally hollow and acts as a torsion member.  A bulkhead is welded in the cross support assembly and is positioned to directly receive forces exerted on the bracket.  Usually the bracket and bulkhead are of unitary construction.  The bulkhead extends within a generally tubular cross-member which also forms a part of the assembly and is attached between the lateral supports and into contact with the interior of the tubular member.  Forces exerted on the assembly are thus generally compressively applied to the bulkhead welds adding to the overall strength of the assembly.

Title: Seaming plastics materials
Inventor: BARTLETT JOHN R
IPC: B29C65/12
Filed: 1978-07-19
Granted: 1981-11-17
Abstract: ABSTRACT     A method of seaming together the edges of plastics sheet by bringing them towards each other, leaving a small gap, and introducing a plastics strip into the groove thus formed.  The strip can be directly extruded into the groove so that it welds directly to the sheet edges.  Alternatively, external heat may be applied, for example by a hot air jet just before the strip enters the groove, so that the strip welds to the sheet edges.  The sheet, and possibly also the strip may comprise foamed plastics material.  The seam thus formed can be rolled before the material has cooled so as to produce a flush joint.     This method can be used to produce tubular plastics bodies for making into containers.  Also disclosed is a method of fitting a metal end closure in which an outward flange on the closure is turned around the outside of the foamed plastics body and engages under an outward shoulder at the rim of the body forming a circumferential seam, the material of the body being compressed between the flange and an upstanding annular wall of the end closure.  An alternative method of producing a flush seam between plastics sheets comprises reducing the thickness of the edge portions of the sheets and then overlapping these portions and sealing them together.  The reduced thickness areas preferably have complementary profiles.

Abstract: Abstract of the Disclosure A  process for purifying the off-gases from indus-trial furnaces and especially from waste incineration plants is described in which process the off-gases which contain acid, neutral and/or basic pollutants in the gaseous or solid form or in the form of a mist, are treated in an evaporative cooler and then in a dry purifier, in which they are freed from at least a substantial portion of the solid pollutants, and finally in a scrubber by means of a wash liquid.  The temperature of the off-gases in the evaporative cooler is kept above the dew point, and the wash liquid in the scrubber is cycled through a slurry separator, from which suspension or solution  of pollutants is with-drawn from the sludge separator and fed into the evapora-tive cooler and mixed in a mixing space  in the latter with the hot off-gases.  Those walls of the evaporative cooler which come into contact with the mixture of off-gases and recycled suspension or solution of pollutants and which consist of a material that can be corroded by the said mixture at room temperature are heated from the outside to a temperature above the dew point. As a rule the pH value of the liquid phase in the sludge separator and in each of the gas wash stages of the scrubber directly upstream of the said separator is kept below 4.

Abstract: ABSTRACT OF THE DISCLOSURE:           The invention pertains to a method for the prepa-ration of polymers, grafted polymers, and copolymers from olefins substituted by polar groups (ester, nitrile or aryl) or from dienes, wherein the polymerization is initiated by a system formed by mixing of an organic amide of alkaline metal with an alkaline metal alkoxide.  The organic amide is derived from primary or secondary amines or polyamines, or from tertiary polyamines containing at least one primary or secondary amine group.  These amines contain N-C or N-Si bonds, 1-4000 C atoms and 1-1000 N atoms in the molecule, or have a molecular weight below 100,000.  The alkoxides are derived from C3-C16 alcohols.  The polymerizations are carried out at -80 to + 80°C, at a monomer/organic amide molar ratio of 5-1500, at a alkoxide/amide molar ratio of 0.5-10, and in hydrocarbon or ether solvents.  The advantage of organic amides of alkaline metals is the easy and economical preparation and suitable and chemical properties (solubility, higher resistance to contamination), while the alkoxide comporent exhibits the superadditive effect on the poly-merization rate and yield and effects the microsructure of polymer.  The method is also suitable for preparation of block copolymers by successive addition of various monomers, block copolymers with polyamine blocks, and grafted polyamine polymers.

Abstract: Abstract of the Disclosure This disclosure describes transparent glass window structures of the typo bearing a first coating of infra-red reflective material which is advantageously less than about 0.85 microns in thickness and wherein the obser-vance of iridescence resulting from such a first coating is markedly reduced by provision of a layer of continuously varying refractive index between the glass and the coating, such that the refractive index increases continuously from the glass to the first coating, thereby preventing the observation of iridescence. The invention also encompasses simple processes for providing such windows.  A particular advantage  of the invention is its efficacy with clear and lightly tinted glasses wherein the problem of iridescent color has had its greatest commercial impact.

Abstract: Abstract of the Disclsoure The present invention relates to a foamed composite material whlch can be used as a light weight construc-tional material or a thermal insulating material having a high mechanical strength, particularly, high tensile strength.  The foamed composite material is made by lining a surface of specific plastic foam with a lining material comprising an unsaturated polyester and vinyl monomer. The specific plastic foam is obtained by expanding thermo-plastic resin particles consisting of polyolefin, vinyl aromatic polymer and a graft polymer formed by graft-polymerization of the vinyl aromatic monomer onto the polyolefin.  The foam may be produced by polymerizing a vinyl aromatic monomer impregnated into particles of the polyolefin to graft the monomer onto the backbone of polyolefln.  The vinyl monomer contained in the lining material penetrates into the plastic foam and hardens to bind the lining layer strongly to the plastic foam.  The coated plastic foam of the present invention is useful as a material for vessels, floats, tanks, buildings and the like.
