Patent ES-484316-A1 (ES)
Title: Apparatus for reading an optical record carrier having a radiation-reflecting information structure
IPC: G11B7/12
Filed: 1979-09-20
Abstract: An apparatus is described for reading a record carrier with an optical radiation-reflecting information structure. The path of the read beam includes a plane-parallel plate, whose surface area is substantially smaller than the cross-sectional area of the read beam, which plate ensures that the beam portion which passes through the plate cannot interfere with the rest of the read beam. After reflection by the record carrier the said beam portion passes through the radiation-deflecting element which deflects the beam portion to two radiation-sensitive detectors. The position of the radiation spot formed by the said beam portion is proportional to the degree of focussing of the read beam on the information structure.

Patent ES-8308813-A1 (ES)
Title: Process for the production of cement.
IPC: C04B7/36
Filed: 1982-10-26
Abstract: In a process of producing cement, the ground raw material is de-acidified in a calcinator and is subsequently burnt in a kiln and before being de-acidified in the calcinator is subjected to a multi-stage heat exchange with exhaust gas streams from the kiln and from the calcinator in two parallel series of heat exchange stages. The stream of ground raw material is delivered from heat exchange stages of each of said series to respective heat exchange stages of the other of said series. In order to improve the thermal efficiency and to reduce the equipment expenditure, the exhaust gas stream from the kiln is caused to deliver heat to the ground raw material in an additional heat exchange stage, which directly precedes the calcinator in the flow path of the ground raw material, and the exhaust gas stream from the kiln is subsequently mixed with the exhaust gas stream from the calcinator. The resulting stream of mixed exhaust gases is uniformly distributed to the two series of heat exchange stages.

Patent ES-8406627-A1 (ES)
Title: Flexible connection apparatus
IPC: E21B17/01
Filed: 1983-08-23
Abstract: A flexible connection apparatus is disclosed for accommodating relative movement between a compliant offshore structure and the sea floor. The compliant offshore structure supports a fluid-carrying system which conveys fluids between the sea floor and the structure. The fluid-carrying system includes a riser and a helical flowline. The lower end of the riser is connected to the sea floor. The first end of the helical flowline is connected to the upper end of the riser and the second end of the helical flowline is connected to the structure. As the compliant offshore structure is displaced from its vertical equilibrium position due to loading forces induced by wind, waves, and ocean currents, the helical flowline elastically flexes through torsional deflection to accommodate such movement. In a preferred embodiment of the apparatus, a wellhead is connected between the riser and the helical flowline such that the centerline of the helical flowline is substantially vertical. In yet another embodiment of the apparatus, a bending flowline is connected between a wellhead and the structure with its centerline being substantially horizontal to accommodate movement of the structure through bending deflection rather than by torsional deflection.
