Title: Process for making sound insulation components
IPC: B60R13/08
Filed: 1977-04-05
Abstract: A process for making composite contoured sound insulating panels of a type suitable for use adjacent to structural panels of automobile vehicle bodies, which in accordance with one embodiment of the present invention, comprises forming a fibrous pad incorporating controlled amounts of a heat curable thermosetting binder and a heat softenable thermoplastic binder distributed in a controlled manner therethrough. The pad is subjected to a preliminary curing step to bond the fibers together into an integral mass, whereafter a dense liquid vinyl plastisol coating is applied to at least one face surface of the pad, which thereafter is heated to effect a fusion of the coating into a heat softened integral layer, effecting a simultaneous heat softening of the thermoplastic binder, whereafter the heated pad is placed between appropriately contoured mold surfaces and is compressed to impart a preselected contour thereto and localized embossments therein and a desired surface finish to the plastisol layer, while simultaneously cooling the pad to effect a rigidification of the thermoplastic binder and the layer so as to retain the composite pad in the preselected contoured and embossed configuration. In accordance with an alternative embodiment of the disclosed process, the pad is subjected to a preliminary molding step followed by the coating step and is subjected to a final molding step after the plastisol coating has been fused at an elevated temperature.
Patent ES-459958-A1 (ES)
Title: Electrical control devices
IPC: G10H5/00
Filed: 1977-06-21
Abstract: An electrical control device comprises a base member, and an elongate support member mounted to be movable transversely of its length with respect to the base member. A tension spring biases the elongate member against movement in one direction transversely of its length and towards a null position. An elongate resistive member is supported by and extends along the length of the support member, and when the ends of the resistive member are connected to opposite respective poles of a voltage source a sensing electrode can be applied to the resistive member to tap off a voltage which is selectively variable by varying the position along the support member at which the sensing electrode is applied to the resistive member. The resistive member is so arranged with respect to the support member that application of the sensing electrode to the resistive member tends to bring about movement of the elongate member with respect to the base member in opposition to the bias established by the tension spring. A position pick-up has a first part connected to the support member and a second part connected to the base member, and the parts are arranged and connected to generate an electrical analog signal dependent on the position of the support member with respect to the base member. The device is also provided with means for generating a predetermined response when the support member is moved from the null position through an initiating threshold position against the bias established by the tension spring and for terminating the response when the support member is returned from beyond the initiating threshold position towards the null position through a termination threshold position.

Title: Method and apparatus for pumping concrete to form structure at elevated heights.
IPC: E04G21/04
Filed: 1981-07-07
Abstract: A method and apparatus is disclosed for continuously pumping flowable concrete mix to elevated heights for introduction into forms used in the fabrication of annular structures such as concrete hyperbolic cooling towers. A tower crane is erected in the center of the circle for the hyperbolic structure and concrete conveying piping is provided for raising mix to a lateral conduit carried by a secondary boom suspended from the swingable overhead jib of the crane. A pumping unit at ground level forces concrete mix up the vertical piping on the tower and then through the boom supported conduit for delivery into the form structure. The jib and thereby the boom suspended therefrom are swingable through an arc of 180 DEG in one direction to cover one half of the form structure and then the jib and boom may be swung in the opposite direction through the remaining 180 DEG arc for introduction of mix into the form structure. The tower crane is of the type having a climbing cage permitting lifting of additional mast units to the top of the stack thereof using the jib as a lifting medium to increase the height of the crane. Corresponding pipe sections on the tower mast units allow delivery of concrete mix to increasingly higher elevations as fabrication of the hyperbolic structure progresses. The length of the secondary boom and thereby the laterally extending conduit supported thereby may be increased or decreased as necessary to accommodate the changing diameter of the hyperbolic concrete shell during construction.
Patent ES-8207361-A1 (ES)
Title: Unit to control the access of processors to a data bus.
IPC: B66B1/18
Filed: 1981-10-20
Abstract: An apparatus for controlling the access of a plurality of microprocessors at a data line. The microprocessors are connected by interface components or blocks, logic switching circuits and bus drivers with two lines or conductors. An access request or demand of a processor initiates a signal change at the first line. This signal change causes the transformation of data which is specific to the processor into a delay or a priority signal, upon the occurrence of which there is accomplished a signal change of the second line. As a function thereof there appears at an input of the interface component a signal change which is indicative of the availability of the data line. Upon simultaneous occurrence of access requests or demands of a number of processors the signal change of the second line is brought about by that processor whose priority signal possesses the smallest delay. The signal change of the second line prevents the occurrence of the priority signals possessing the greater time-delays and which are correlated to the remaining processors. At these processors there thus cannot occur any signal change at the input of the related interface component or block and which indicates the availability of the data line.
