Patent ES-447961-A1 (ES)
Title: Burning of pulverous or granular raw materials
IPC: F27B7/38
Filed: 1976-05-14
Abstract: A method is disclosed for burning pulverous or granular raw material such as cement raw meal in a rotary kiln plant by directing a first flow of raw material to a cyclone preheater, preheating the first flow of raw material in the cyclone preheater, and directing the preheated raw material from the cyclone preheater to a rotary kiln for burning the material in the kiln. The burnt kiln product is directed to a cooler which may be of several types and which communicates with the material outlet of the kiln while a second flow of fresh raw material is directed to the cooler to at least partially cool the burnt kiln product by transferring heat therefrom to the second flow of fresh raw material in the cooler. The method further involves combining the preheated, at least partially calcined second flow of material with the first flow of preheated, at least partially calcined material prior to directing the combined flows to the rotary kiln and thereafter directing the combined flows to the kiln for burning and for subsequent cooling in the cooler. The invention also pertains to a unique kiln plant for practicing the inventive method.

Title: Optical switch.
IPC: G02B6/35
Filed: 1978-08-25
Abstract: {PG,1 An electrical optical fiber switch includes first, second and third optical fibers located so that a lateral movement of the first optical fiber breaks optical connection with the second and makes optical connection with the third. The first optical fiber is coated with an electrically conductive substance which is electrically switched to a positive or negative side of a DC voltage source. Electrodes disposed adjacent to the first fiber are connected across the voltage source. Depending on the resulting polarity of the first fiber coating, the first fiber is electrostatically moved between the electrodes so as to accomplish optical switching. A dielectric coating or barrier is provided on the first fiber coating or on the electrodes so as to prevent electrical contact. Many such optical fiber switches can be provided on a planar optical switch board for optical test terminations in an optical fiber communications system.
