Patent ES-424385-A1 (ES)
Title: Adsorptive separation of aromatic isomers with adsorbents containing an alcohol substrate
IPC: C07C15/08
Filed: 1974-03-18
Abstract: An adsorptive separation process for separating para-isomers from a hydrocarbon feed containing a mixture of aromatic isomers, including the para-isomer, which process employs a crystalline aluminosilicate adsorbent containing an alcohol substrate to selectively adsorb the para-isomer from the feed. The alcohol substrate substantially increases the selectivity of the adsorbent for the para-isomer with respect to the other aromatic isomers, thereby improving the efficiency of the separation process. In one specific embodiment the use of an alcohol substrate increases the selectivity of the adsorbent for para-xylene sufficiently to permit the use of a benzene-containing desorbent to remove the adsorbed para-xylene. Because of its lower boiling point, a benzene-containing desorbent avoids fractionation difficulties that may result when a toluene desorbent is used while processing a non-extracted C8 aromatic feed stock.

Title: Apparatus for the wet processing of textile strands
IPC: D06B3/28
Filed: 1975-12-15
Abstract: An apparatus for the wet processing of textile strands including a kier with several drums therein, each drum being supported by rollers in the bottom of the kier for rotation about the central axis of the coaxial drums. The drums have central openings to permit the strand to be fed into and out of the drums in sequence. Jetting-in devices are associated with each drum to inject the strand under fluid pressure and reels are provided to guide the strand from the drums and to the respective jetting-in devices. A liquid circulating system withdraws processing liquor from the bottom of the kier and injects the liquid under pressure to the jetting-in devices. The drum walls are perforated. In one embodiment, the strand is recirculated through a series of drums in sequence and through a pipe extending through the central openings in the drum from the last to the first of the series. In a further embodiment the strand is passed through the sequence only once and the kier is provided with feed and discharge conduits with additional reels, jetting means and fluid recirculating means for guiding the strand. Walls at the ends of the kier adjacent the feed and discharge pipe connections establish pressure traps which are fluid filled to permit a pressure differential to be established between the interior and exterior of the kier. Systems employing multiple kiers of the type disclosed are also shown with interconnecting conduit arrangements to minimize the total height of the feed and discharge pipes and to maintain proper pressure differentials.
Patent ES-443614-A1 (ES)
Title: Two-stroke I.C. engines
IPC: F01L3/20
Filed: 1975-12-18
Abstract: A two-stroke internal combustion engine has a plurality of transfer ports controlled by the movement of the piston, the transfer ports being at the ends of passages each extending from the interior of the crankcase through the cylinder wall so as to place the crankcase interior in communication with the upper working space in the cylinder above the piston when its associated transfer port is uncovered by downward movement of the piston. Some, but not all, of the transfer port passages are provided with pressure-responsive non-return valves which are lightly spring-biassed towards closed positions in which they restrict the gas flow through those passages, in the direction towards the upper working space in the cylinder, causing the gas flow from the crankcase to travel at increased velocities through the remaining transfer port passage or passages. When the pressure differential between the crankcase interior and the upper part of the cylinder exceeds a predetermined minimum value the non-return valves open to permit bulk gas flow through their associated transfer port passages and their associated ports.

Patent ES-459671-A1 (ES)
Title: Method and apparatus for reactive sputtering
IPC: C23C14/50
Filed: 1977-06-10
Abstract: A reactive sputtering process is described for producing a thin film of sputtered material on a tubular substrate which may, for example, be a solar collector tube. Uniformity of the composition of the sputtered layer at all points at the same depth in the film is achieved by preventing the movement of reactive gases through which the sputtering has already taken place, from one part of the zone of sputtering to another. In one way of achieving this result the reactive gas is swept from the zone of sputtering by entraining it in a gas stream flowing across the sputtering path. In an alternative way of achieving this result the rate of flow of reactive gas is finely controlled so that it is entirely consumed in one discrete area of sputtering so that there are no components of the reactive gas remaining which are free to move to other parts of the zone of sputtering and thereby change the atmospheric conditions in it. Apparatus for carrying out these two functions is described and utilizes tubes, which may be electrodes, formed with lines of holes or openings extending parallel to the axis of the tubular substrate on which the sputtered film is to be formed.

Patent ES-466472-A1 (ES)
Title: Apparatus for coating glassware
IPC: B05B15/12
Filed: 1978-01-30
Abstract: This invention relates to the art of coating glassware while the ware is moving through an annealing lehr which is provided with a cooling section near the exit end of the lehr. The cooling section is of the continuous recirculation type providing an arrangement for generally cooling the ware to a relatively even temperature even though the ware is moving through the lehr in multiple rows and columns. The ware is moved through the lehr on a lehr belt which is formed as a webbed belt and constitutes a foraminous conveyor. A lubricious material in the form of a vapor or mist of an organic, nonmetallic coating material selected from the group consisting of polyolefins, fatty acids and their derivatives is injected into the recirculating cooling air in the cooling section of the lehr to thereby form a durable lubricious coating on the exterior surfaces of the glass article. The articles, at the time they are passed through the cooling section, will be at a temperature between 200 DEG F. and 400 DEG F. The vapor generator used to form the vapor or mist has an outlet tube of at least one foot in length extending vertically from the generating chamber to avoid injection of any condensate into the cooling section of the lehr.

Patent ES-473772-A1 (ES)
Title: Resilient pivotal joint.
IPC: F16C27/06
Filed: 1978-09-28
Abstract: An improved pivot joint (10a) has a rotatable and tiltable stud (12a). A rotational preload force is applied to the stud (12a) by a bearing (16a) which is circumferentially stressed in tension to apply a clamping force to the stud (12a). This clamping force resists rotation of the stud (12a) relative to a housing (14a) until a predetermined minimum rotational force is applied to the stud (12a). A tilting or sidewise preload force is applied to the stud (12a). A tilting or sidewise preload force is applied to the stud (12a) by a resiliently compressible bushing (18a) which is disposed between the bearing (16a) and the housing (14a). Since the tilting preload force is applied to the stud (12a) by the bushing (18a), the bearing (16a) can be designed to provide an optimum rotational preload force without regard to tilting preload force design considerations. Similarly, the bushing (18a) can be designed to provide optimum tilting preload forces without regard to design considerations influenced by the rotational preload forces. The pivot joint (10a) is advantageously assembled by resiliently expanding the bearing (16a), moving the stud (12a) into alignment with the bearing (16a) then releasing the bearing (16a) so that it contracts part way back to its initia condition. The diameter of the stud surface (26a) engaged by the bearing (16a) is large enough so that the bearing (16a) cannot fully retract back to its initial condition. This results in tension stresses being set up in the bearing (16a) so that it applies a clamping force against the stud (12a) to hold it against rotation. The bearing (16a) is provided with stop means (112) which limit sideward tilting movement of the stud (12a).
