Patent AT-A220091-A (AT)
IPC: C11C3/04
Filed: 1991-11-06
Abstract: PCT No. PCT/AT92/00136 Sec. 371 Date May 6, 1994 Sec. 102(e) Date May 6, 1994 PCT Filed Nov. 3, 1992 PCT Pub. No. WO93/09212 PCT Pub. Date May 13, 1993.A process is disclosed for preparing fatty acid esters of short-chain monohydric aliphatic alcohols or monoalkylated diols by basically catalyzed esterification of natural, partially or totally synthetic fatty acid glycerides, as well as fatty acid glyceride-based waste products, such as used frying oils. The process is characterized in that the unpurified fatty acid glycerides, containing in particular high proportions of free fatty acids and phosphatides, (a) are esterified in one or several steps in the presence of a basic catalyst with an excess of short-chain alcohol or monoalkylated diol; (b) the glycerin phase produced after the first esterification step is at least partially added to the second or following step, after sterification has been carried out, and the mixture is stirred; (c) the glycerin phase is again separated, the supernatant fatty acid ester is cleared of excess alcohol or diol, then treated with a possibly diluted organic or anorganic acid, and if necessary filtered. This process, that is carried out without pressure and heat supply, is characterized by a technically simple implementation by means of simple equipment, and by a high degree of purity of the thus obtained fatty acid esters.

Abstract: The insertion piece consists of a cover strip and anchor pieces which are preferably metal, such as an aluminium alloy, and a rubber intermediate layer. A groove near the gap takes an elastic piece which is partly bounded by the cover strip, the intermediate layer and the anchorpieces. The lateral fixture part of the expansion piece grips behind the jaw touching the groove on the cover strip or anchor pieces. The top of the cover strip is ridged, and the underneath side has an upward pointing dome shaped into which fit raised parts of the anchor pieces. The space between the anchor pieces and cover strip is filled with the rubber intermediate layer. The centre part of the anchor pieces has a lengthwise notch also filled with the rubber intermediate layer.

Patent CA-1041999-A (CA)
Inventor: BALME MAURICE
IPC: C07D207/452
Filed: 1973-10-01
Granted: 1978-11-07
Abstract: La présente divulgation est relative à un procédé de déshydratation d'acides bis-maléamiques par chauffage avec un anhydride d'acide carboxylique inférieur dans l'acétone, en présence de 0,2 à 1 mole d'amine tertiaire par mole d'acide bismaléamique et d'un dérivé soluble du nickel, puis précipitation du bis-maléamide et éventuellement des produits secondaires formés, par addition d'eau au mélange réactionnel final.  Ce procédé est caractérisé en ce qu'on ajoute aux produits de départ de 0,1 à 10 moles d'eau par mole d'acide bis-maléamique soumis à la déshydratation.  Le fait d'incorporer de l'eau aux produits de départ permet d'accroître la proportion de bis-ma-léamide dans le produit final précipité.  Par ailleurs, cette adjonction d'eau permet paradoxalement d'augmenter le taux de la réaction de cyclodéshydratation.  Cette dernière conséquence constitue un avantage certain pour l'obtention de polymères lorsque celle-ci fait appe? à la technique du moulage par compression.  En effet, dans la mise en oeuvre de cette technique, il est souhaitable que le matériau à conformer présente le moins possible de produits volatils ou de groupements précurseurs de produits volatils dans les conditions de température adoptées. Or ce procédé permet de diminuer considérablement dans le produit final précipité la proportion de groupements maléamidoacide aptes à libérer de l'eau au cours d'un chauffage ultérieur sous pression.  Dès lors, le produit final précipité peut être utilisé tel quel pour de nombreuses applications sans qu'il soit nécessaire de le soumettre à une opération préalable visant à purifier le bis-maléimide formé.

Abstract: GLAZING SYSTEM          ABSTRACT:         Interior and exterior glazing strips hold a window glass or panel in place in a structural frame that has an opening slightly larger than the glass or panel.  The glazing strips have a resilient reinforcing member with an elastomeric material extruded over and covering the reinforcing member.          Receivers for the glazing strips have channels shaped to inter-lock with and hold the glazing strips around the periphery of the frame, and the reinforcing member extends from the gripping portion of the strip into the base of the strip interlocked with the channel.  The reinforcing member resiliently presses the retainer portion of the glazing strip against the window glass or panel with a force of approximately 4-6 pounds per linear inch around the periphery of the window glass or panel.  The invention provides economy, reliability, safety, and long life duribility in a glazing system for securely holding a variety of window glass and panels in place.  The inventive glazing system also allows replacement of window glass or panels from the exterior of the buliding after original installation of window glass or panels from the interior of the building.

Abstract: Abstract of the Disclosure A phase mask comprised of a rectangular array of phase shifting areas arranged in a pseudo-random pattern is illuminated with a beam of electromagnetic radiation.  The array of pseudo-randomly phase shifted beams is focused on a Fourier transform plane on which the power spectrum of the beams distributes in two orthogonal directions from its center maxima.  The phase shifting areas are arranged in such a manner that there is an approximately equal number of phase shifts for each of the different phase shifting areas with a constant phase relation between orthogonally adjacent phase shifting areas.  The center maxima of the spectrum is confined to a rectangular-shaped area and uniformly distributed by suitably selecting the number of different phase shifts.  Coherent noise on the reconstructed image is effectively eliminated.

Abstract: PROCESS FOR PACKAGING AND STORING FOOD ITEMS                  Abstract of the Disclosure In the preparation and storage of cooked, bulk packaged food in flexible receptacles, the quality of the food is increased, the cooking conditions are closely controlled, the growth of bacteria is  restricted, and the storage time is increased by reducing the interior temperature of the food from its filling temperature of at least 180°F  to below 45°F in less than a half hour.          Said temperature reduction is preferably achieved by filling the receptacle so that the food therein is flowable or mobile and then tumbling the receptacle in a cooling medium so that the food flows or moves within the receptacle.   After storage at 28°F  to  32°F,  the food may be heated by tumbling the receptacle in a heating medium  in order to bring the food quickly to serving temperature thereby avoiding overcooking.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus is capable of forming a tubular filter element of a filter material on a tubular mandrel which has a hollow interior and a cyl-indrical outer surface.  A press roller within the mandrel forces the mandrel against a pair of drive rollers which can be rotated to cause the mandrel to rotate.  The filter material is inserted between the drive rollers and the mandrel to cause it to be wound about the mandrel as the press roller applies sufficient force to insure that the filter material will be tightly wound about the mandrel.  If the filter material is a nonwoven filter media of cur-ed glass fibers or uncured glass fibers which have been set up from exposure, the glass fibers are reactivated by wetting prior to being wound about the mandrel.  If the filter material is a screen material, a tensioning device further insures that the screen will be tightly wrapped about the mandrel.
