Patent ES-343609-A1 (ES)
Title: Conveyor systems
IPC: B65G47/31
Filed: 1967-07-31
Abstract: An endless conveyer 10 is, in the main, driven at a speed slightly in excess of the speed of a second endless conveyer 12 to which it transfers trays 11 for engagement by the pusher lugs 37 on the second conveyer 12, the speed of the first conveyer 10 being temporarily reduced below that of the second conveyer when the trays arrive in advance of the lugs. An arm 73 driven in synchronization with the conveyer 12 interrupts a photo-electric cell 74 when a lug 37 is in a position to receive the leading tray 11 and a further photo-electric cell 75 registers the trays 11 when in a position in advance of the desired position for synchronized feeding to the lugs 37 such that when the photo-electric cells are simultaneously interrupted a servo-motor 48 is operated to drive the planar wheels of an epicyclic gear-box 41, the input of which is driven from the drive means 40 of the second conveyer and the output of which drives the first conveyer, so as to effect a reduction in the speed of the conveyer 10. The period of operation of the servomotor is variable. A pair of endless belts 18 having a foam rubber article engaging surface 21 are disposed on opposite sides of the conveyer 10 to guide the trays therefrom on to a pair of endless belts 62 disposed between the conveyers 10 and 12 and driven at a higher speed thereto to remove the trays clear of the photo-electric cell 75. The conveyers 18, 62 are driven from the drive means for the conveyer 12, through appropriate gearing.

Title: Method of and apparatus for sorting crystals according to size
IPC: B01D9/00
Filed: 1969-11-15
Abstract: A device for sorting crystals according to their size comprises a separation chamber divided into two parts a fluid carrying the crystals to be sorted passes into a first of these parts while a separate driving fluid is passed into the second, the flow-rate of fluid passing out of the second part being less than the flow-rate of driving fluid which passes into the second part, while the flow-rate of fluid passing out of the first part is higher than the flow-rate of carrier fluid passing into the first part, whereby at least a portion of the driving fluid passes across an interface separating the two parts, in counter-flow to the largest crystals to be sorted the crystals to be sorted tend to flow from the first part to the second but the upward speed of the driving fluid in the separation chamber prevents such flow except for the crystals having the desired diameter, regulated by the speed of the fluid.

Title: Electromagnetic control, especially for crossing gates of toy and model railroads
IPC: A63H19/36
Filed: 1970-07-13
Abstract: An electromagnetically operated control device, especially for a toy and model railroad, in which a disc is driven slowly in rotation by a vibrating armature and on one side has an eccentric for actuating a reciprocable element and on the other side has a plurality of annular contact paths engaged by contact fingers. When a coil adjacent the armature is energized to set the disc in motion, one contact path thereon provides for keeping the coil energized for 180 DEG of travel of the disc while another contact path provides for intermittent sounding of a signal during one of the periods of rotation of the disc. The initiation of coil energization can be accomplished by manual switches or by switches operated by a train on the track of the railroad. The disc may cause a crossing gate to swing down to closed position during one 180 DEG of travel of the disc and then to swing up to open position during the next 180 DEG of travel of the disc.

Title: Time division multiplexer employing digital gates and a digital-to-analog converter
IPC: H03M1/00
Filed: 1973-08-17
Abstract: This invention relates to a high frequency multi-channel time division multiplexer employing digital gates and a digital-to-analog converter. An analog voltage is continuously applied to one input of an analog comparator. The output of a digital-to-analog converter is applied to the other comparator input. A sequencer turns a first channel digital gate ON, and a 10 bit binary number representing the input voltage is produced using the conventional half-split approximation technique. After the conversion has been completed, the digital gate in the next channel is switched ON and the process is repeated. The 10 bit binary number is stored in the digital-to-analog converter and made available in parallel form at the end of each conversion. When the last channel has been converted, the sequencer again energizes channel 1. The output multiplexer output is a PCM wave train.

Title: Model motor racing track - has drive motor reversing control circuit which enables one car to overtake another
IPC: G09B9/048
Filed: 1977-12-06
Abstract: A model motor racing track has an inner (20) and outer track (22) each with three conductor rails (A,B, C). Each rail (A, B, C) supplies power to a model car (24, 26, 28) respectively. Each car has an electric motor which can drive either one of its rear wheels through a gear train. In order to overtake the car in front a switch (136) on the control box (124) or (126) is actuated which reverses the direction of the electric motor in the car. This reversal of motor direction transfers the drive to the opposite wheel but still drives the car in the same direction. Transferring the drive to the other wheel causes the car to be diverted to the inner track and press against the inner rail (16).

Title: Noise and cross-talk elimination in recording and reproducing video signals
IPC: H04N9/79
Filed: 1978-06-15
Abstract: In apparatus for recording and reproducing video signals in successive parallel tracks of reduced width and without guard bands therebetween so as to achieve a high recording density on the magnetic tape or other record medium, and in which a high frequency portion of the video signals, for example, the luminance component of color video signals, is frequency modulated for the recording thereof, processing circuits are operative in the recording and reproducing modes of operation to act on the luminance component prior to its frequency modulation in recording and after its demodulation in reproducing, respectively, for substantially eliminating from the demodulated luminance component the usual FM noise signal and also any interfering signal due to cross-talk, for example, as results from a lack of H-alignment between the signals recorded in adjacent tracks when the apparatus is intended to be operated with two different tape speeds. Such processing circuits provide non-linear pre-emphasis and substantially complementary non-linear de-emphasis in recording and reproducing, respectively, with the amounts of pre-emphasis and de-emphasis being dependent on the level and frequency of the signal being recorded and reproduced and preferably also dependent on the level-frequency characteristic of the interfering signal due to cross-talk appearing on reproduction.

Title: Improvements in and relating to explosive cladding.
IPC: B23K20/08
Filed: 1979-01-17
Abstract: A method of applying a surface layer across a surface layer or joint between cladding layers on a clad metal plate or plates comprises forming a shallow chamfer along each opposing cladding layer edge and positioning over the said chamfers a corrosion resistant metal flyer-plate having a shallow generally V-shaped configuration, optionally applying a buffer layer of transmitting medium placed on the outside surface of the flyer-plate, further superimposing an explosive layer upon the cladding and buffer layers and detonating the explosive layer so as to weld the flyer-plate material at least to the cladding layers. Advantageously a metal groove may be formed in the base metal layer of the clad plate to facilitate positioning of the flyer-plate, the groove wall conveniently being extensions of the cladding chamfer surfaces. The method facilitates an assembly of a cladding strip and explosive layer over a joint between clad metal plates in any orientation and gives joints of high quality between the cladding layers on the plates.
