Patent ES-459091-A1 (ES)
Title: Method and apparatus for preheating combustion air while cooling a hot process gas
IPC: F23L15/04
Filed: 1977-05-24
Abstract: A heat transfer apparatus for cooling a hot process gas to a temperature close to its dew point without condensation. The hot gas passes through a first chamber while air to be heated passes in an adjacent second chamber. A series of fluid containing tubes extend back and forth between the two chambers. The fluid continuously flowing through the tubes extracts heat from the hot gas and transfers it to the air to be heated.
Patent ES-460229-A1 (ES)
Title: Carbon black process with inner and outer hot combustion gas entries providing protective blanket and extra hot gases for conversion of feed
IPC: C09C1/50
Filed: 1977-06-29
Abstract: In the usual elongated carbon black furnace which is provided at one end with a combustion gas entry section, usually of diameter larger than the remainder of the reactor, in lieu of the usual entry port or ports providing hot combustion gases with which to decompose the make oil or gas to carbon black, there are provided independent, double-entry port or pipes. At each double entry there is an outer port and an inner port or pipe. Usually, the pipe approaches the enlarged section or precombustion chamber somewhat tangentially and at a substantial right angle to the longitudinal axis of the elongated reactor or furnace. Thus, viewing the furnace end-on, the outer port or entry will spew its fluid near and onto the walls of the precombustion chamber while the inner port or entry will deliver its gases to a point nearer the longitudinal axis. By feeding so as to obtain a blanket of relatively cool gas adjacent the walls of the precombustion chamber by means of the outer port and a relatively much hotter gas through the inner port, the walls of the chamber are protected while at the same time the make oil or gas can be subjected immediately to a great deal more heat and higher temperature such that higher yields of carbon black are obtained. A novel furnace precombustion zone structure is disclosed.

Patent ES-467235-A1 (ES)
Title: Multiple switch assembly with detent and interlock
IPC: H01H13/12
Filed: 1978-02-22
Abstract: Disclosed is a multiple switch assembly including first and second push-push switches positioned side by side. The operating member of the first switch carries a shoulder which cooperates with a peg on the second switch operating member so as to move the second switch along with the first switch when the first switch is moved from a first to a second position. Additionally the second switch carries a resilient strip which during movement of the second switch beyond its second position, is deflected towards and engages the first switch operating member. The resultant movement on the first switch operating member releases it from its detent such that by pushing said second operating member, said first and second switches are returned to their respective first positions. The resilient member acts as an effective interlock element to assist in the retention of the operating members in the depressed position and the automatic return of both operating members to the first position.

Patent ES-8200314-A1 (ES)
Title: Shaping glass sheets using molds of different shapes
IPC: C03B23/03
Filed: 1980-09-24
Abstract: Shaping glass sheets by lifting a heat-softened glass sheet on a lower mold having an upwardly facing surface defining a given sharpness of bend and transferring said glass sheet by suction to an upper vacuum mold having a downwardly facing shaping surface defining a lesser sharpness of bend. Optionally, a ring-like member defining a sharpness of bend that may be equal to, less severe, or more severe than that defined by the upper vacuum mold moves between the molds when the latter are separated to impose a shape in the glass sheet that is correlated with the shape defined by the ring-like member. The ring-like member is used to support the glass sheet for rapid cooling if the glass sheet is to be tempered. Only the ring-like member need be changed when a change in production pattern is made.
Patent ES-8301779-A1 (ES)
Title: Active seat suspension control system and vibrometer therefor.
IPC: F16F15/04
Filed: 1981-09-18
Abstract: A virbometer 16 has a mass 50 suspended for vertical movement by a light spring 82 so that the mass tends to stay at a constant height reardless of angulations in the ground over which the vehicle carrying the system is travelling. The vibrometer provides one height signal by way of a potentiometer 46 and a second potentiometer 40 provides a second signal representing of the drivers seat 12. An error signal formed by a comparator 44 controls a hydraulic double acting actuator 18 so as to make the seat 12 follow the mass 50 and accordingly tend to maintain a constant height in absolute terms. In order to prevent the system becoming unstable when the ground is very rough, the mass opens limit switches 20, 22 at upper and lower limit positions and, when either switch is open, a relay 98 drops out and a solenoid valve 24 disables the actuator by connecting the two inlets 62, 64 of the actuator cylinder 60 together via a slow resistor. The relay is also deenergized when the ignition switch 26 is off. The potentiometers 46, 40 are connected between two circuit arms 36, 38 and a variable resistor 54 in the energising circuit provides gain control, ie sensitivity control. Ganged resistors 110, 112 in the two arms provide stiffness control and a resistor 116 solely in the arm 38 adjusts the main seat height. The relay 98 is of a latching relay which is reenergized by a reset switch 28. Operations of this switch sets the gain control resistor 54 to minimum gain. In a preferred construction of the vibrometer, the mass is suspended from the end of a lever arm projecting from one end of a torsion rod having the other end fixed.
