Patent ES-430305-A1 (ES)
Title: Cooxidation process for the production of dimethyl terephthalate
IPC: C07C67/313
Filed: 1974-09-23
Abstract: Disclosed is an improvement in the cooxidation process for making dimethyl terphthalate (DMT). In the cooxidation process an oxidate comprising monomethyl terephthalate and p-toluic acid is esterified with methanol to form a reaction mixture comprising DMT and methyl p-toluate, methyl p-toluate is separated from the reaction mixture, and p-xylene and said methyl p-toluate are cooxidized in the liquid phase with molecular oxygen to form more oxidate, which is esterified, etc. The improvement comprises separating p-toluic acid from part of the oxidate prior to esterifying the oxidate, and cooxidizing separated p-toluic acid with said p-xylene and said methyl p-toluate. This improvement results in a lesser quantity of oxidate subjected to esterification, and a reduction in the quantity of methyl p-toluate cooxidized with p-xylene.

Title: Fluid impulse matrix printer
IPC: B41J2/22
Filed: 1976-03-26
Abstract: A printer is disclosed for use in printing indicia or the like on a sheet of recording medium by selective application of impulses of fluid. The printer comprises a sheet support mechanism, a print head, fluid supply means, a valve assembly, and an input system. The support mechanism supports and selectively advances the sheet of recording medium. The print head includes a one- or two-dimensional array of tubes arranged to form a dot matrix for printing alphanumeric characters on the sheet. It may extend the width of the recording medium or be movable across it. Connected to these tubes are the fluid supply means and a valve assembly that includes a separate valve for each tube for controlling the supply of fluid thereto. In one embodiment of the invention, a heater raises the temperature of the fluid passing through the tubes enough that printing takes place on the recording medium whenever the fluid is ejected from the tubes. In another embodiment, a movable pin is mounted at the distal end of each tube in such a fashion that it is driven into the recording medium when a valve is opened. In still another embodiment the movable pins are also heated enough that they affect the recording medium where they are driven into it. The input system opens and closes the valves in accordance with input signals, such that the impulses of fluid applied to the tubes produce detectable visual changes on the recording medium which represent such input signals.

Title: Method of making a pipe coupling and method of curing a polyester resin body
IPC: F16L21/00
Filed: 1980-03-01
Abstract: A pipe coupling comprises a body of fiber glass reinforced plastic which has a rubber sleeve embedded therein. The sleeve is a one piece unit which includes specially shaped sealing gaskets on either end and has a rubber liner spanning the area between these sealing gaskets. The sleeve is stretched onto a steel and plastic molding mandrel, which places the rubber liner under tension, reduces the cross- sectional area of the liner and compensates for thermal expansion of the liner during curing. The mandrel/sleeve combination is rotated in order to wind a thermosetting resin impregnated fiber glass roving around the outer circumference of the mandrel/sleeve combination, thus embedding the sleeve in the fiber glass reinforced resin matrix. The thermosetting resin is cured at elevated temperatures, hardening into a rigid coupling with the embedded rubber sleeve integral therewith. Thereafter the hardened coupling is stripped from the steel and plastic mandrel and subjected to a further curing and finishing operation. The curing of a polyester body with a peroxide while in contact with a rubber surface is also claimed.
