Patent ES-354487-A1 (ES)
Title: Controlling the granulometry of material
IPC: B02C25/00
Filed: 1968-05-30
Abstract: The inner crushing cone of a conventional gyratory crusher is automatically controlled to maintain a predetermined particle size distribution in the crusher output. The method of control (see Division G2-G3) involves the measurement of various outputs of the crusher by a screen, weighers and conveyor belts, Figs. 2, 3 and 4 (not shown) and the detection of the axial position of the inner cone 17 by the arrangement shown in Fig. 5. The shaft 19 of this cone turns inside a collar 20 fixed in respect of rotation by flexible parts (not shown which absorb the eccentric displacements of the shaft. Axial displacement of the shaft 19 is detected by a fork 15 engaging a ball or cylinder 22 at the end of a feeler 21 secured to the collar 20. Fork 15 is connected to a second feeler 23 freely slidable in a cylinder 24 and carrying a finger 23a engaging a link of an endless chain 26 passing over three cogged wheels, Fig. 6 (not shown). A contactor 16 turns with one of these wheels and, by means of its electrical connections with other multi-contact ganged switches in the automatic control system, Fig. 7a (not shown), effects the recording and control of the movements of the inner cone. These movements'are effected by a motor/pump unit and valves which respectively supply fluid to or withdraw it from the suspension actuator of the inner cone. A protection arrangement automatically takes control to open the valves and prevent operation of the pump unit should the fluid pressure in the suspension actuator exceed a predetermined value. The protection arrangement automatically returns the inner cone to its position existing before the overload and automatically interrupts the power supply to the pump and valves should more than a predetermined number of successive overloads occur. There is also described, Fig. 8 (not shown) a manual control for adjusting the position of the inner cone having a collar and feeler arrangement generally similar to that of Fig. 5, the second feeler co-operating with a switch housed in a casing which is manually adjustable relative to the frame of the crusher.

Patent ES-362234-A1 (ES)
Title: Assembling a lead wire to a terminal through a spring
IPC: H01R43/04
Filed: 1969-01-08
Abstract: A method of assembling a component lead wire 2 to a terminal 8 through a spring 6 comprises positioning the wire at one end of the spring and across its longitudinal axis, forming a bight in the wire and moving the bight through the spring, compressing the spring, locating a part of the wire bight in a ferrule of a terminal and securing the terminal to the wire. A carbon brush 4 of a dynamo-electric machine is placed in a cradle 76 and the wire 2 is located in a notch 104 in a wall 106 of a frame block 48, where it is retained by a spring 108. A brush spring 6 is placed in a channel 50 in registry with a notch 116. Compressed air is then supplied to a piston-cylinder assembly 74 causing a primary slide block 54 to move to the left in Fig. 8 towards a secondary slide block 84 and a threading rod 26 moves against the wire to form a bight therein. The bight is pushed through the spring 6 and through an opening in the end of a plate 162. When the slide block 54 meets the slide block 84, it is moved with the cradle 76 and the brush towards a crimping zone and movement of the wire 2 relative to the rod 26 ceases. At the same time a pin 142 on the block 54 moves along a cam surface 146 on a lever 132 thereby allowing it to pivot anticlockwise under the influence of a spring 140 to allow a plate 114 to move over the spring 6 and retain it in the channel 50. At the end of the stroke of the slide blocks 54, 84, a ram 40 begins its downward stroke and immediately afterwards a pin 34 is lowered into a notch 36 in the rod 26. Further movement of the ram causes the pin to move in an arcuate path by the action of a cam 240 engaging a roller 238 on a bell crank arm on which the pin 34 is mounted. This arcuate movement aligns a portion of the bight with the ferrule of a terminal and as the ram 40 completes its stroke a die 188 crimps the ferrule to the wire and a shear blade cuts off the surplus wire. As the ram starts its return stroke the slide block 54 is returned to its initial position by a spring 102 via a chain and sprocket drive. The slide block 84 remains in position as it is engaged by a latching boss 160 on a lever 154. As the slide block approaches the end of its travel the pin 142 engages camming surfaces 146, 150 to move the levers 132, 154 thereby moving the plate 114 clear of the channel 50 and allowing the slide block 84 to return under the influence of the spring 102. During this return stroke, the spring 6 expands pulling the terminal 8 off of the crimping anvil and after the assembly has been removed from the apparatus, the wire is threaded through a slot 18 so as to bring the end of the spring to bear on the terminal. In an alternative embodiment, the threading rod is formed with a hook-like slot near its tip. It is passed through the brush spring before picking up the wire and the bight is formed as the rod is withdrawn through the spring.

Title: Method and apparatus for simultaneously recording on film time displaced segments of an electrical signal
IPC: H04N5/84
Filed: 1970-03-25
Abstract: Video signals from pairs of successive fields produced by a television camera 10a are recorded on black and white cinematograph film in interlaced relationship in a single film frame. To shorten the number of film frames needed to record a program of a plurality of pairs of interlaced television fields the signals are passed through a one-field period delay means 18, and the delayed and non-delayed luminance signals are alternatively sampled at 27 at a frequency high relative to a line period whilst the spot producing the raster on the printing cathode-ray tube 28, Fig. 1, is subjected during the display to a castellated line scan, Fig. 2A, of said sampling frequency, such that the successive luminance fields are laid down in a dot-interlaced manner, e.g. field 1 on line portions 39 and 42 and field 2 on line portions 41 and 43. Vertical sync. pulses control the continuous film drive. To ensure that the delay of the delayed video signal is exactly one-field period, a small variable delay 19 is used, servo controlled by the output of a phase detector 22 determining the phase difference between sync. signals from the delayed and non-delayed video signals. The high frequency sampling signal is produced by generator 27a and is also added at 34 to the vertical deflectors signal from the tube 28. As an alternative to the above sequential sampling with a single beam, a recording beam tube 281, Fig. 3, using two beams may be used, beam 1 recording lines 39a, 42a, Fig. 2B, from the delayed first field of a pair and beam 2 recording interlaced lines 41a, 43a1 from the second field of the pair. Continuous film movement is again used, and each field is recorded twice in consecutive film frames. In the arrangement of Fig. 4 a twobeam tube 2 is again used. Delays 62 and 64 delay the successive fields A 1 , B 1 , A 2 , B 2 , A 3 , B 3 &c. for one and two-field periods respectively. A gate 66 passes the undelayed field signals, and the two-field period delayed signals on successive fields under the control of sync. generator 16. Beam 1 is modulated with the output of the gate 66 and beam 2 with the output of delay 62. The action of the circuit may be summarized by the following table:

Patent ES-435124-A1 (ES)
Title: Deflection system
IPC: H04N3/18
Filed: 1975-02-27
Abstract: A horizontal deflection system is operable either from rectified and filtered alternating current line voltage or from a substantially lower voltage direct current voltage source. The need for a step-down transformer in the receiver power supply is eliminated by utilizing the horizontal output transformer to drop the rectified and filtered alternating current voltage when the receiver is operated in the alternating current line mode. The horizontal output transformer is utilized as a step-up inverter when the receiver is operated from the low voltage direct current source to produce a direct current voltage at a point on the horizontal output transformer substantially equal to the rectified and filtered alternating current line voltage.
