Title: Heating process and its apparatus in reducing air pressure within a chamber at a balanced level
IPC: D06F58/28
Filed: 1981-07-10
Abstract: This invention relates to a heating process and its apparatus in reducing air pressure within a chamber at a balanced level. The air within the sealed chamber is suctioned forcibly and discharged thereoutside by rotation of rotary means installed to the chamber. Then, the air pressure therewithin gets reduced at a balanced level. Meanwhile, air friction heat is generated by continuous rotation of the rotary means, thereby the inside of the chamber is heated by air friction heat. Any wet articles are incorporated in the chamber may be dried effectively, and energy consumption for heating and drying may be saved. Further, since high temperature heated air fully fills the chamber, the chamber itself may be used as a heat source.

Title: Method of deforming plastics pieces.
IPC: B29C67/00
Filed: 1982-01-26
Abstract: Shaped articles, particularly tubular shaped articles, are formed by a process comprising molding a crosslinkable synthetic plastic material into a first molded shape, crosslinking the plastic material at a temperature in excess of the crystalline melting point of the material, subjecting the crosslinked first shape to a working operation to form a second configuration shape and subjecting specific areas of the second shape to a heat treatment thereby forming a deformation in the specific area. Extruded tubular materials subjected to a stretching operation tend to seek their original shape upon heat treatment thereby making the degree of deformation possible nearly equal to the degree of stretching.

Title: Method of producing fibre-reinforced flat bodies containing a hardenable binder.
IPC: D04H13/00
Filed: 1982-07-23
Abstract: A process for the preparation of fiber-reinforced flat bodies containing a hardenable binder is described, wherein a core layer containing the prepared, unhardened (liquid) binder is placed between a cover layer and a backing layer in order to provide this three layer body with its own internal cohesion even in the unhardened condition and to improve the mechanical properties of the body in the hardened state, the three layers, at least one of the outer ones of which consists of fibers capable of active fiber bonding, are needle bonded together prior to the hardening of the binder, so that the layers will hold together in the deformable state, whereupon the binder is hardened, while the fibers provide the body with an elasticity different from that of the hardened core layer. Prior to hardening, the composite body may be provided with orifices or slits, without the loss of the mass of the core layer from the body. The mass of the core layer is held by holding fibers, introduced during the needle bonding process and connecting the cover layer with the backing layer through the core layer.

Patent ES-8504609-A1 (ES)
Title: Splice-in-register control
IPC: B65H21/02
Filed: 1983-06-13
Abstract: A web-feeding machine used to provide a continuous supply of material having successive labels and registration marks printed serially thereon includes an assembly for splicing the material from a ready web to the material severed from a running web. The splicing assembly has a response time T after being actuated by a control system. The control system comprises a driving circuit for electromechanically actuating the splicing assembly, a scanner positioned adjacent the material to provide a signal in response to the presence of a registration mark, and an encoder for providing a fixed number of pulses proportional to a corresponding length of the moving material. The control system also comprises a control circuit connected to the scanner, the encoder and the driving circuit. The control circuit counts the number of encoder pulses Bo between successive scanner signals and then decrements from that number Bo to zero. In addition, the control circuit provides a time delay To preset to approximate the response time T and then decrements to zero from a preset number D after the time delay To has expired. When the control circuit reaches zero, it stores a decremented value X representing the contemporaneous number read while decrementing from Bo to zero. The control circuit then decrements from the value X and provides a splice signal SS upon reaching zero. Finally, the driving circuit energizes the splicing assembly in response to the splice signal SS to accomplish a splice-in-register.
Patent ES-8405726-A1 (ES)
Title: Process of preparing sulphur granules.
IPC: C01B17/02
Filed: 1983-10-05
Abstract: Sulphur granules are prepared by burning a gas containing sulphur compounds, converting the sulphur formed into a melt and separating this melt from the combustion mixture, spraying the melt into or onto a bed of sulphur particles kept in motion and in contact with an oxygen-containing gas stream, discharging the granules formed and recycling at least part of the gas discharged from the granulator as combustion gas. The advantages of the present process are a substantial reduction of off-gases causing environmental pollution and also a reduction of the required amount of optionally preheated combustion gas.
Patent ES-8503258-A1 (ES)
Title: Method for classifying sand
IPC: B03B5/60
Filed: 1984-03-23
Abstract: A method for classifying sand wherein a mixture of sand and water is introduced into a classification tank (7) partially filled with water. Depending on the weight of the sand grains, the grains of sand will precipitate at the bottom (8) of the tank (7) at graduated distances from an inlet pipe (6), the heavier particles nearest the inlet and the lighter particles farther away. To prevent large quantities of fines, i.e., sand grains between about 0.002 mm and 0.006 mm in size, from being lost by being washed out of the tank (7) together with the overflow water, the water from the tank (7) is recirculated by means of a pump (14) so that the water becomes progressively more saturated with fines, which means that larger amounts of fines will precipitate in the tank (7). Because the water is recirculated, water consumption can be reduced by 2/3, and at the same time the problem of the overflow water from the tank (7) is also reduced.
