Patent ES-473864-A1 (ES)
Title: Corn harvester
IPC: A01F11/06
Filed: 1978-10-02
Abstract: A corn harvester has a chassis adapted to travel along the ground and provided on its front with an intake mechanism for picking ears off the cornstalks and for reducing these ears to fragments including pieces of cob, corn kernels, and pieces of husk. These fragments are displaced backwardly onto a ridged floor having a rear edge spaced by an upstream gap from a riddle having in turn a rear edge spaced upwardly by a downstream gap from a comb. A blower directs a current of air through these gaps to separate out the chaff-like husk pieces, while the smaller and denser fragments can drop through the riddle and be collected. Both the riddle and the floor are oscillated to displace the fragments backwardly. A second comb meshes with the first comb and has a plurality of tines that are continuously displaced through the tines of the first comb to separate out husk pieces from the fragments on the first comb. Thus only the corn kernels and pieces of cob will pass through the riddle or the first comb whereas the husk pieces will be separated out.

Title: Continuous furnace for e.g. sintering nuclear fuel pellets - incorporates stop-start mechanism giving exact regulation of heating time
IPC: C04B35/64
Filed: 1978-12-21
Abstract: A method of regulating exactly the time of heating of a material, partic. nuclear fuel pellets in course of being sintered, in a continuous furnace, consists of conveying the material discontinuously through the furnace. The material is advanced at exactly predetermined time lapses DELTAt, at a rate greater than that which would be necessary for continuous passage, and it is stopped after a predetermined course, but before the end of each time lapse DELTAt. Process avoids the problems associated with variations of speed of the conveying system due the frictional forces on the trucks on which the material is being transported through the furnace. Such variations can lead to differences in the times during which the material is held in the furnace, and therefore to differences in quality.

Title: Two=stage ceramic item press - has separate devices for first and second pressing stages also aiding other operations
IPC: B30B11/02
Filed: 1979-02-09
Abstract: The press is for ceramic or similar items, using powder as the material, two press operations being necessary. It has separate devices forthe first phase and the second press operation, these being combined with others to provide conditions for suppression of movement, initial expulsion of air and an intermediate phase. Pistons(5, 5') can be used for the first phase, and combined with the weight of a support(3) for the second, while for the third these pistons and the support weight are combined with other pistons. For the fourth phase, the first pistons(5, 5') and support(3) are used, less the force of the pistons. The final compression phase is effected by a screw(7') with flywheel(7").

Abstract: Transmission of data signals using an optical array keyboard. Light sources 1 and collimators 2 sequentially direct a light beam 8 along the rows of an array of beam-splitting elements, 3, controlled by keys 4. When an element 3 is placed in the path of a beam 8 it reflects part of it towards one of the detectors 7 placed in the columns of the array, but allows the other part to pass towards the other elements 3 situated downstream, thus permitting detection of the state of the other keys of the same row, and resolution of the problem relating to the situation where a key is depressed before the previous one is released. The keyboard can be used as a unit for inputing data into a data processing system.

Patent ES-8300578-A1 (ES)
Title: Secretarial shift mechanism for an electric keyboard
IPC: H01H13/70
Filed: 1981-02-03
Abstract: A secretarial shift mechanism which includes two shift keyswitches and one shift lock keyswitch is disclosed. The two shift keyswitches have T-shaped actuating bars secured to their plungers. The shift lock and release keyswitch has a generally C-shaped wire spring retainer placed around its housing which is utilized to secure a hook on a latching finger on a ledge that is formed on the plunger of the shift lock keyswitch. The latching finger is secured to an elongated torsion bar which has a pair of arms at the ends of the bar that are bent toward the two shift keyswitches. The torsion bar is held at its ends against the frame that holds the keyswitches of the keyboard by clamping caps that project from the shift keyswitches and have grooves in them that receive the torsion bar therein. When the shift lock keyswitch is depressed, a hook on the latching finger that is secured at the torsion bar engages a ledge on the plunger of the shift lock keyswitch and holds it down. Depression of either of the shift keyswitches causes the T-bar on the keyswitch to engage the bent arms on the torsion bar, which in turn results in twisting of the torsion bar sufficiently to deflect the latching finger so the lock is off of the ledge which releases the shift lock keyswitch from its actuated condition.
