Title: Mejoras en máquinas para la cosecha de la cana de azúcar
Inventor: RODRIGUEZ MORALES JOSE A
IPC: A01D45/10
Filed: 1976-05-05
Abstract: Mejoras en máquinas para la cosecha de la cana de azúcar consistentes en la combinación de partes de estas máquinas con construcciones nuevas y la cual se aplica en un equipo autopropulsado que recolecta los tallos de cana cortándolos a ras, los trozos es pequenos pedazos, eliminando las materias extranas que van unidas, entregándolos posteriormente a un medio de transporte. La recolección se produce con ayuda de una cámara que tiene los órganos de levante y corte inferior de los tallos y tambores para la alimentación los cuales entregan la masa vegetal cosechada al aparato trazador para cortarla en pedazos adecuados. El aparato trozador se diferencia de los conocidos en que los tambores poseen distintos diámetros, así como que las cuchillas de corte están dispuestas en forma excéntrica, lo que garantiza una menor holgura en un mayor ángulo de rotación. La limpieza tiene lugar primero con un aparato para cortar los cogollos antes de recoger los tallos y después al ser lanzada la masa vegetal desde el transportador hacia la batería de tambores horizontales que dispersan esta masa separando las materias extranas con ayuda de la fuerza de presión dinámica de un flujo de aire que se aplica en sección casi horizontal. Otra limpieza se produce al caer la masa desde el transportador de descarga al medio de transporte aplicando nuevamente sobre ella un flujo de aire en succión casi horizontal. De esta manera se eleva la eficiencia de toda la máquina y la productividad con un alto índice de limpieza y bajas pérdidas de cana, siendo capaz esta de trabajar en campos de altos rendimientos agrícolas y cosechar cana verde sin necesidad de aumentar las dimensiones de la máquina ni elevar el gasto de potencia.

Title: Improvements in and relating to switch gear for controlling electric motors
IPC: H01H9/26
Filed: 1919-07-10
Abstract: 166,084. Hirst, J. A., and Brook, P. S. July 10, 1919. Controllers, actuating.-Relates to motor controllers in which backward and forward oscillation of a handle or other operating member advances the controller in angular steps from an "off" position to a "full-on" position, and a subsequent advance of the controller in the same direction brings it round to the "off" position. In one construction according to the invention the complete apparatus comprises a gear-box, Figs. 1 and 2, mounted on the outside of an ironclad casing A. Fig. 8, and a drum controller C with its associated auxiliary switches and contacts inside the casing. Fig. 6 shows the assemblage of parts diagrammatically and their electrical connections. The gear-box consists of a stationary part 1 and a rotatable part 1<a> carrying a handle 2<a>. By rocking the handle backwards and forwards through about 450, a ratchet wheel 3b is advanced in corresponding steps. A claw coupling 3a communicates this motion to the controller drum, which advances progressively from the "off" position, through six intermediate running positions to a "full-on" position, closing different contacts at each successive step. In all except the " full-on " position, the handle 2<a> must be held twisted about its spindle 2 in order that a cam 2d may act upon a shaft 5, which exerts pressure on a long rod 5<c>, Fig. 8, and keeps the main curcuit closed through a switch D. If the operator loses the handle it is untwisted by a spring 2e, and the main current is broken. In the "fullon" position, a contact on the drum short-circuits the switch D. Sections of starting-resistance are cut out during the advance of the drum in the usual manner. Subsequent variation of speed may be obtained by a shunt field regulation 22. A locking-magnet 7<e> may be provided for the purpose of holding the controller in the " full-on ' position. When it is required to move the parts to the "off" position a stop button 21 is momentarily opened, thereby de-energizing hold-on coils 19<a> of main circuit-breakers 18 and cutting off the supply. The operator then works the handle until the controller is brought round to the " off " position. Specifications 118,324 and 155,614 are referred to.

Abstract: 176,932. McLachlan, N. W. Jan. 5, 1921. Relays.-A relay device for obtaining considerable force from a small current consists of coils B', B<2> enclosed in an iron or steel drum D fixed on a shaft A which is constantly rotated. The coils are supplied with current by means of sliprings C<1>, C<2>. A band E, on which are iron or steel shoes, passes partly around the drum D and is attached at either end to springs G'. When signalling current passes through the coil B<2>, the magnetic drag on the band E causes it to be dragged round with the drum against the spring G' and this movement may be arranged to deflect a siphon tube by means of a bell-crank lever L. One of the coils may be connected to a local battery, and according to the Provisional Specification the drum D may be polarized by a permanent magnet. Two such relays may be used to operate a signalling-key, the bands over two drums rotating in opposite direction having an end of each connected on opposite sides of the fulcrum of a key, the relay coils being in series but oppositely wound. Two bands may be coaxial and connected by hoops of brass or aluminium, one band being attached directly to the key.

Title: Process for the production of olefines of low molecular weight, more especially ethylene
IPC: C07C11/04
Filed: 1956-01-10
Abstract: In a process for the production of low molecular <PICT:0802696/IV (b)/1> weight olefines, particularly ethylene, from liquid hydrocarbons by thermal cracking at a temperature above 750 DEG , preferably 850 DEG  C., heat is continuously supplied to ceramic heat carriers by the direct introduction of flue gases containing, if any, no more than 2 per cent, preferably 0.5-1 per cent by volume of free oxygen and obtained by burning any fuel.  The flue gases may form all or part of the carrier gas for the hydrocarbon.  The flue gases can be formed in a separate chamber 11 in which case part of the flue gases may be led through pipe 16, cooled, if necessary, by cold gases introduced through pipe 18, so that the heat carrier bed is hotter than the mixture of hydrocarbon and carrier gas, and mixed with atomized or vaporized hydrocarbon which has been preheated in container 1.  The remaining flue gases enter through 10 to heat the heat carriers in the reaction bed 8.  Alternatively the flue gases are formed in situ in a space above the heat carriers and the liquid hydrocarbon is sprayed into the flue gas.  In this case the fuel which is preferably gaseous is mixed with oxygen or oxygen-containing gas and burned with a short flame.  Other carrier gas may be introduced with the fuel.  Methane and hydrogen formed in the cracking process may be separated from the olefines and used as fuel for the production of the flue gases.
