Title: Process for preparing calcined gypsum
IPC: C04B11/00
Filed: 1978-03-11
Abstract: An apparatus and process for preparing calcined gypsum which comprises continuously treating a mass of calcined gypsum by adding, with thorough blending, metered portions of water to the calcined gypsum. The water is incorporated into the calcined gypsum as a continuous, free-falling stream immediately after the gypsum enters the blender container near the top of its sidewall. The water must be added carefully so as not to contact either the side wall of the blender container or the propeller blade mounted in the center of the apparatus on a shaft projecting upwardly from the bottom and with the propeller spaced from the bottom of the container. The water is added in amounts ranging from about 1 to about 16% of free water by weight of the calcined gypsum fed to the blender apparatus. The calcined gypsum fed to the blender, after adding the water, is swept down the side wall of the container, flows around the propeller, and then is swept up the side wall to an exit port preferably located near the top of the side wall and near the port where the gypsum enters the container.

Title: Power supply regulator using impulse modulation - with diode and capacitor for controlling transient voltage changes and Zener diode giving reference voltage level
IPC: H02M3/156
Filed: 1979-04-20
Abstract: The regulator provides a constant voltage output. It employs a control circuit (7) for varying the supply pulse width in order to maintain the output voltage. To damp out voltage fluctuations in the load a compensating circuit comprising a diode (16), capacitor (17) and resistor (18) is connected to one output terminal (C). A sudden rise in output voltage charges the capacitor (17) and leads to an immediate change in pulse width. A fall in voltage is blocked by the diode, and a delayed change in impulse width follows depending upon the time constant of the capacitor circuit. The control circuit pulse width modulator has a ref. voltage input provided from the mid-point of a resistor (8) and Zener diode (9).

Title: Colour reference control for SECAM system TV receivers - uses DC levels derived from sampled and stored signals via common potentiometer
IPC: H04N11/18
Filed: 1979-12-13
Abstract: The control system is for TV receivers using the SECAM colour system.

Patent ES-8200923-A1 (ES)
Title: Continuous process and apparatus for modifying carbohydrate material
IPC: C08B31/00
Filed: 1980-12-17
Abstract: A process and apparatus are described for producing a modified carbohydrate material, preferably starch, in fluid form. In the process a starch slurry is continuously moved through a confined tubular preheat zone where heat is very rapidly transferred to the slurry, whereby the slurry passes through a gelation stage and forms into a hot free flowing liquid. The heat transfer is from superatmospheric steam surrounding at least part of the tubular heating zone, the temperature of the steam and the cross-sectional area of each tubular preheat zone being selected to rapidly transfer heat from the steam throughout the slurry and minimize the magnitude of the zone of high viscosity gel formed during the gelation stage. The hot liquid formed is immediately forced through a restrictive opening and into a confined tubular reaction zone accompanied by a sudden decrease in pressure whereby the starch is made highly reactive. The reactive starch liquid, together with a reactive adjunct such as acid, is then continuously moved through a tubular reaction zone to produce a modified starch product in fluid form. A steam heated reactor for the above process is also described.

Title: Process for recovering metals from metallic salt solutions.
IPC: C22B7/02
Filed: 1981-04-15
Abstract: The process for recovering metals of the 1st, 2nd, 4th, 5th, 6th, 7th and 8th sub-group of the periodic law from solutions of their salts, particularly from solutions containing hydrochloric acid contemplates as the first process step a neutralization (1) for precipitating the metals from their acid metal salt solutions in the form of hydroxides or carbonates. The precipitate is pressed (4), and via conduits (9, 10) finally divided metal of the metal having been present as a salt as well as a carbon source originating of waste materials, particularly in form of ground heat setting synthetic plastics materials such as phenolic resins, amine formaldehyde resins, epoxide resins, polyesters, and also CaCO3 is added. All components of this mixture must be used in a fine-grained state and preferably with a maximum particle size of 0.5 mm. Subsequently, the mixture is via a conduit (11) introduced into a reduction reactor (12) in which this mixture is mechanically agitated and heated to a temperature above the melting point of the metal in consideration for reducing the metal being present as a salt. For recovering the heat content of the effluent gasses as well as for purifying the effluent gasses, the effluent gasses formed during the reduction and containing CO and CO2 are subjected to a post-combustion (15) and used for drying the pressed metal precipitate. The effluent gasses coming from the drying zone are washed (18), the washed water being preferably used for heating the metal salt solutions to be neutralized.
