Patent ES-344264-A1 (ES)
Title: Phase Locked Oscillator System
IPC: H03L7/14
Filed: 1967-08-19
Abstract: An automatic phase control system includes means for storing the phase error and producing from the stored signal a replica of the output of the phase discriminator for use if the supply of reference signal is interrupted. In Fig. 1 the phase discriminator 2 has an output comprising pulses of a width corresponding to the phase error, and these pass to unit 11 where they are used to gate clock pulses passing from the source 18 to the counter 10. The count stored in the counter 10 therefora corresponds to the current phase error, and is used to select, from waveforms produced by units 13-15 and 17, a waveform corresponding to the stored count and approximating to the output waveform of the discriminator 2. Normally AND gate 6 is open and gate 5 closed, but if the signal form the reference source 3 is interrupted a detector 9 reverses the condition of the two gates to allow the waveform from unit 13 to pass through the low pass filter 4 to control the oscillator 1. Each sampling cycle is preceded by a reset pulse from unit 19 which resets counter 10, and by a timing signal from source 12 which enables the gating unit 11.

Title: Walking beam furnace
IPC: F27B9/20
Filed: 1969-01-04
Abstract: In a furnace 20 incorporating a walking beam conveyer having a fixed set of tubular rails 64 and a reciprocable carriage 100 with a movable set of rails 94 for intermittently and alternatively holding and conveying a series of slabs, blooms or billets 80 during their passage through the furnace, said carriage is mounted on a pair of parallel girders 102 vertically reciprocated by six eccentrics 160 and is driven longitudinally by a pair of crank-shafts 204 through connecting rods 220. The eccentrics 160 are driven in unison from a single electric motor through a series of right-angle drives 164, main shafts 170, pinions 166 and ring gears 168. Another motor drives the crank-shafts 204 through a drive train including pinion gears 210 and ring gears 208. The rails 64 are supported by tubular columns 62 with end columns 621, 6211 formed by extensions of said rails, cooling water being supplied by columns 621 and taken off by columns 6211. Elbow pipes extending down the columns 62 divert water therethrough (Fig. 8). Rails 94 are similarly supported by columns 92 which extend through slots 96 in the furnace hearth 26 formed with skirts 122 depending into longitudinal water troughs 124 to form seals. The rails 64 and 94 are covered with refractory and formed with pads 82 supporting the workpieces 80. Fixed paddles 136, 138 in the reciprocated troughs 124 urge scale into an accumulator 140 at the end of each trough 124. Each accumulator is flushed by operating a pneumatic motor 142 lifting a plunger 144 with a plug 146 to allow scale and water to escape into a discharge trough 152. At the top of the plunger stroke a closure member 150 shuts off the flow of water. Workpieces 80 are pushed on to an entry table 234 by a ram 232 and extractor arms 236 reach into the furnace and serially lift them on to an extractor table 238. The furnace has upper burners 50 and lower burners 52 in the side walls which also have flue ports opening into a valve-controlled chimney 54 at each side.

Title: Apparatus for testing the road-tire adhesion of a vehicle
IPC: B60T8/58
Filed: 1971-05-19
Abstract: The apparatus gives information relative to the road-tyre adhesion of a vehicle, comprising an electronic anti-skid device so as to allow the driver to appraise or to know the distance over which move during a panic braking before coming to a stop or before slowing down to a safe speed. The apparatus comprises a pulse-width measuring circuit for measuring the duration of the isolation signals which are developed in the anti-skid device for temporarily isolating the braking system. The information can be displayed by colored lamps. However, the apparatus can comprise more elaborate indicating means delivering signals which can be converted into direct readings or into signals representative of the theoretical braking distance. The comparison of these signals with signals delivered by a range finding device measuring the distance separating the vehicle from an obstacle ahead allows a warning signal to be obtained when the distance is unsafe.

Patent ES-411517-A1 (ES)
Title: Dynamoelectric machine cooled by a rotating heat pipe
IPC: F28D15/02
Filed: 1973-02-12
Abstract: A dynamoelectric machine is described wherein heat generated within the rotor is removed utilizing a heat pipe rotating about the rotor shaft. Heat is absorbed from the rotor by vaporization of a portion of the refrigerant within a rectangular evaporator juxtaposed with the heat generating region of the rotor whereafter the vaporized refrigerant flows radially inward (due to centrifugal forces acting upon the higher density liquid refrigerant) to pass to a condenser coil secured to the rotor at a relatively cool location. Upon cooling to a liquid state in the condenser, the liquid refrigerant is forced radially outward along the condenser coil to return to the evaporator through a radially outer orifice. Preferably, the evaporator is situated within the rotor coils, e.g., at the center of the field pole winding of a synchronous machine, although the evaporator also could be positioned along any radially extending side of the rotor coil. Because refrigerant passes from the evaporator to the condenser and returns to the evaporator solely by centrifugal forces acting upon the closed cooling system, a separate refrigerant pump is not required to cool the motor.

Patent ES-424447-A1 (ES)
Title: Data switching apparatus and method
IPC: H04Q11/04
Filed: 1974-03-20
Abstract: A method and apparatus for switching PCM data in a telephone exchange wherein the switch is of the time-space-time (TST) type comprising a plurality of identical inter-connected groups, each group having two separate planes in which connections may be established. A plane select bit of data is added to each speech sample before switching through the space switching stage. The plane select bit influences a logic circuit at the switch output to determine which plane provides the outgoing data. For reliability connections are duplicated, that is, made in both planes until congestion occurs and when congestion occurs a new call is made in a path of one of the planes previously used for duplication. Information relevant to unduplicated connections is stored in a memory external to the switch to enable unduplicated connections to be re-established if they should be lost due to a fault. The switch has the advantage of being congestionless without necessitating a large external memory for storing information relevant to unduplicated connections.
