Abstract: Abstract The invention relates to a sturdy I-girder. In the previously used corresponding girders, for example in I-girders made of laminated wood, it has not been possible to adjust the dimensioning so that bending stress, shearing stress and bending flexure would all have been equal dimensioning factors, and so it has been necessary to overdimension the girder. The object of the invention is in particular to eliminate this disadvantage and to achieve thereby a considerable saving in material. This is achieved by making the web of the girder from continuous multi-ply wood with 10-60 %, preferably 30 %, of its plies being such that their grain orientation is transverse in relation to the web length and the remainder of the plies being such that their grain orientation is parallel to the web length. The booms of the girder are made from multi-ply wood the plies of which have their grain orientation parallel to the web length.

Patent CA-1225049-A (CA)

IPC: B65D33/22
Filed: 1983-11-18
Granted: 1987-08-04
Abstract: ABSTRACT       Joints in packing containers of heat-sealable gas-tight laminate are sensitive to deformation, since this often results in a deterioration of the gas-tightness.  This is due to the accumulation of melted thermoplastics which is produced during the heat-sealing.  The said weaknesses are eliminated in that the sealing zone of the joint is given a limited width and is placed at a distance from the edge of the laminate.  A method and an arrangement for realizing this comprises a heating zone whose width is limited in relation to the width of the sealing jaws which are used for the sealing together of the material layers.

Abstract: Abstract Composite electrode structure A nonporous composite electrode,  particularly suit-able for use in electromagnetic flowmeters, includes a non-metallic, electrically conductive element con-sisting of a fused mass of polymeric material, such as  perfluoroalkoxy  (pfa)  fluoropolymer,  and carbon fibers.   The  electrode  is  fabricated  by  stacking alternating layers of polymeric film and carbon fiber paper, subjecting the assembly to sufficient heat and pressure to intermix the two components and bond them into a coherent mass, and fusing the resultant com-posite material onto a mounting pin.  Using a poly-meric material compatible with the polymeric  liner of an electromagnetic  flowtube allows the  Finished electrode  to  be  fused  into  the  liner,  again  by application of heat and pressure, so as to achieve a seamless  interface.   This  configuration  virtually eliminates process fluid leaks around the electrode, while the electrode structure itself exhibits excep-tional high temperature stability and corrosion re-sistance.

Abstract: ABSTRACT OF THE DISCLOSURE:           The present invention is concerned with the modification of starch by silanes.  The modification takes place with concurrent use of organic solvents in a way that the starch is brought into intimate contact with the silanes in the presence of metal acid esters of metals of the 4th or 5th sub-groups of the Periodic System of the Elements.       It is appropriate if the silane and the metal acid ester is dissolved in organic solvent and the starch is introduced into this solution.  After a sufficiently long reaction time, the starch is separated off and then shows better processing properties than correspondingly unmodified starch.  With the metal acid esters, the alkoxy groups can also be replaced by complex formers; suitable as silanes are both alkylalkoxy-silanes and also organofunctional silanes.  The modified starches produces according to the process of the invention may be used as binder for mineral fibres, as textile auxiliary, as sizing agent for different paper purposes as well as filler for plastics.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of producing a via in the fabrication of a semiconductor wafer is disclosed.  Vias are used in semiconductor wafer fabrication as a means of pro-viding electrical connections between different layers of the water.  The walls of known vias are difficult to coat reliably with metal because, particularly in the case of fabrication processes aimed at small line widths, the vias must be kept within certain size limits and neces-sarily have vertical walls.  The method described involves the formation in a layer of dielectric material of two communicating passageways.  One passageway has sloping walls to facilitate metal coating.  The other passageway has substantially vertical walls, thus keeping the via within required dimensions at the region of the wafer to which a connection is to be made.  The two passageways are produced in separate process steps, a non-erodable layer being used to define the via.

Reacting the 1,3-dioxolane derivative with lithium aluminum hydride provides the desired 2,2'-disubstituted-1,3-dioxolane-4-methanol derivative. If an alcohol is not used as described above, then the 2,3-dihydroxy-propanoic acid is reacted with a selected aldehyde or ketone or the acetal or ketal derivative to prepare the 1,3-dioxolane derivative.  The dioxolane derivative is then reacted with lithium aluminum hydride to provide the desired 2,2'disubstituted-1,3-dioxolane-4-methanol derivative.     The compounds so prepared are intermediates in the preparation of optically active beta-agonists or antagonists.
