Patent ES-458497-A1 (ES)
Title: Method of and apparatus for sorting light refuse fractions
IPC: B07B13/00
Filed: 1977-05-05
Abstract: A light refuse fraction including flat pieces of different rip resistance, such as relatively rip-resistant synthetic-resin foils and textiles and less rip-resistant paper, is separated by first suspending the material in a gas stream which is passed over an entrapment element. This entrapment element is so oriented that pieces of the material catch on it. The speed of the stream of gas relative to the entrapment element is such that the less rip-resistant pieces tear free from the entrapment element and the more rip-resistant pieces remain caught on it. Thereafter a stripper element serves to clear the more rip-resistant pieces off the entrapment element and segregate them from the less rip-resistant pieces. In this manner it is possible to recover from the light fraction separated out in a refuse-sorting plant the flat pieces of paper that are recycled for use in making paper products.

Abstract: An automatic gain controlled chrominance signal amplifier system for a color television receiver is arranged to process composite chrominance signals having burst and image-representative components. First, second and third amplifier stages are provided for amplifying the image-representative components. The first amplifier also amplifies burst components and is gain controlled in a first closed loop arrangement to maintain a substantially constant amplitude for the burst component and to thereby maintain an appropriate gain for image components. The second and third amplifiers are coupled to the output of the first amplifier. The output of the second amplifier is coupled to a chrominance signal overload detector arranged to respond to image-representative signal components having peak amplitudes greater than a predetermined level. A gain control output provided by the overload detector is coupled to each of the second and third amplifiers to vary their gains in a manner to prevent undesired oversaturation of the displayed image. A further gain control adjustment (e.g., viewer operated) is coupled to the third amplifier but not to the first or second amplifiers. Apparatus is also provided for shifting the operating threshold of the overload detector.

Filed: 1979-04-05
Abstract: A method and apparatus for processing vehicles which are moved through a conduit by air through sequential zones one, two and three. Preferably, the zones are inclined downwardly towards downstream for aiding movement of the vehicles downstream by gravity. Zone one is a storage zone which preferably has vents adjacent its upstream end and its downstream end for controlling the speed of movement of vehicles into zone one and from zone one to zone two. Zone two is the processing zone which receives vehicles from zone one and releases the vehicles to zone three. Zone two includes an air blocking vehicle stop at its downstream end against which a first vehicle is held, and includes a holding arm which holds a second vehicle while the leading first vehicle is released. The first vehicle is released to zone three, but only when three is clear of vehicles and a second vehicle is positioned behind the first vehicle. Thereafter, the second vehicle is released and moves to the downstream end of zone two and becomes the leading vehicle for continuing the cycle. Additional vehicles moving through the conduit are decelerated in zones one and two with the aid of air trapped behind the air blocking vehicle stop and/or parked vehicles. An accelerator may be provided in zone two for providing a rapid start of the leading vehicle from zone two into zone three. Vehicle position sensors are positioned in the various zones for sensing the presence of vehicles and controlling the movement of the vehicles through the conduit.

Title: Process for the Manufacture of Texturized Polyester Yarns Having Improved Mechanical Properties
IPC: D02G1/02
Filed: 1979-12-07
Abstract: A process for manufacturing texturized polyester yarns from preoriented polyester yarns comprises imparting to the yarns a false twist (13) and concurrently drawing them (11-14) while heat setting them (12), subsequently subjecting them to a second heat setting (15), and collecting the texturized yarn (18). The temperature of the heat setting means and the speeds of the means which impart to the yarns their motion are subjected to critical conditions. Namely, the temperature of the first heat setting means is lower than 200 DEG C, the temperature of the second setting means is not higher than that of the first heat setting means and is preferably lower and the yarn undergoes a retraction, preferably between 8% and 16%, during the second heat setting. Preferred temperatures are 190 DEG C for the first heat setting means and from 160 DEG C to 190 DEG C for the second heat setting means. The texturized yarns thus obtained have increased elongation and tenacity and are greatly improved as to crimp rigidity and crimp contraction.
