Title: Extractor-inserter for Silentblocks
IPC: B25B27/02
Filed: 1979-10-10
Abstract: Silentblocks are extracted from, and inserted into, their housings by movement, in the case of extraction, with an extractor pin 13 and, in the case of insertion, along an inserter pin 13'. In each case the pin passes through the bore in the silentblock. The extractor pin 13 is provided with clamping means 16 to secure it in position. The inserter pin 13' is provided with housing abutment means to prevent relative movement between the housing and pin and silentblock abutment means 19 to push the silent block along the pin. Both pins have threaded ends 14 for selective attachment in the bore 15 of the shaft of a piston 6 and cylinder 1 arrangement. On movement of the shaft through a limiting sleeve 2 attached to the cylinder, the end of the limiting sleeve abuts, in the case of extraction, the housing and, in the case of insertion, the silentblock abutment means to extract or insert the silentblock.

Patent ES-8300215-A1 (ES)
Title: Flight simulator.
IPC: G09B9/28
Filed: 1981-11-06
Abstract: A flight simulating system is provided with a manually operated control member connected to a servomechanism which responds to manual input by the control member and reacts to provide realistic feedback to the control member in accord with simulated flight conditions. For this purpose, a combining circuit, a dividing circuit and two integrator circuits are provided in series. The combining circuit has an input which represents manual input force to the control member and another input from the flight-simulating computer which represents simulated internal forces acting on the controlled member and the dividing circuit divides the output of the combining circuit by a value representing the mass of the control member to produce a control member acceleration-related signal. This acceleration-related signal is integrated twice to produce, respectively, a control member velocity-related signal and a control member position-related signal. These various signals are fed back to the servomechanism to provide a response which produces the correct "feel" at the control member for the flight condition under simulation.
Patent ES-8305647-A1 (ES)
Title: Registration control for a label cutoff apparatus
IPC: B26D5/34
Filed: 1981-11-19
Abstract: A registration control circuit for a printed label cutoff machine controls both the location of the cut by performing a phase adjustment and the length of the individual labels by performing a base speed adjustment. A strip of labels have eyemarks printed thereon for defining the location at which the individual labels are to be cut. An optical scanner is positioned adjacent the labels and generates a scanner pulse upon detection of an eyemark. The control circuit includes a setup control for automatically running the machine into registration from an initial setup position. The setup control functions to generate a reference pulse a predetermined distance before the scanner is expected to see an eyemark. When the eyemark is detected within a designated window area the control utilizes the scanner pulse and the reference pulse to calculate the phase error for each label and generate a phase correction signal proportional to the actual phase error. Individual phase error signals are combined to determine the average phase error which has occurred over the last predetermined number of labels. The average phase error is representative of an average base speed error. If the average phase error exceeds a predetermined threshold, the control will generate a base speed correction signal proportional to the average base speed error. When the eyemark is detected outside the designated window area, the control will attempt to bring the eyemark within the window area by performing a full speed phase adjustment. If, after a predetermined number of consecutive labels, the eyemark has not been moved within the window area, the control will check the base speed and perform a base speed adjustment. The control also includes an alphanumeric display for displaying to an operator, on a prioritized basis, messages indicating the operating status of the machine.

Title: Reactor for the gasification of solid carbonaceous materials
IPC: B01J8/18
Filed: 1982-06-04
Abstract: In a reactor for gasification of solid carbonaceous materials in a fluidized bed under elevated pressure and at high temperatures using a hot gasification agent, a feed device for the gasification agent is installed in the lower part of the reactor chamber and traverses this chamber in the form of a bridge, which has an arch joined to the walls of the reactor chamber, said arch consisting of refractory brick and supporting a section of metal pipe. The latter is shielded from the outside by the arch and by a top-mounted structure of refractory material. On the inside, the metal pipe is also provided with a tubular lining of refractory material. Metal pipe, lining, and arch have openings for passage of the gasification agent. The size and shape of the openings are selected to assure passage of the gasification agent even if the parts undergo changes in length as a result of the effects of temperature. The metal pipe section also serves to absorb the forces resulting from the positive pressure of the gasification agent inside it, as well as for the purpose of metering and distributing the gasification agent in the interior of the reactor.
