Patent ES-351443-A1 (ES)
Title: An Electrical Connection Device
IPC: H01R13/595
Filed: 1968-03-09
Abstract: In a plug 2 and socket 1 assembly (Fig. 1), comprising housings 5, 3 which have respectively a rib 7 (Fig. 8) and a co-operating groove 8 (Fig. 6) to permit assembly in one relative angular position only, and which enclose contact-carrying insulating inserts 9, 11, the inserts are positioned at angles dependent on the voltage to be used by securing them to intermediate elements 13, 14, which are preassembled in one of a selected number of positions. The intermediate elements 13, 14 are formed with a plurality of bores 16 and are secured to the housings by means of dowel-pins 17, and to the inserts by screws. The socket insert 9 contains contact sleeves 10 and the plug insert 11 corresponding contact pins 12. One sleeve and one pin are earthed, and the earthed contact is situated on a radius through the alignment means 7, 8 or at one of a fixed number of angles thereto. The intermediate elements 13, 14 may be circular flat plates or rings made of metal or insulating material. The plug insert 11 has a locating pin 27, so that on insertion into the plug housing 5, the element 14 only allows passage if the position of the pin 27 corresponds to the aperture 28. Since the element 13 has no such aperture, the insert 11 is prevented from entering the wrong housing. Closure covers 21, 22, screwed into and forming part of the inserts 9, 11, have, in their edge regions, marginal recesses 24 interrupted by supporting feet (25), through which screws attach the covers to the elements 13, 14 (Fig. 2, not shown), and to the tension relief means 32, a guiding projection of which 31 (Fig. 11, not shown) co-operates with a recess 30 in the inner edges of elements 13, 14, so that the insert is correctly aligned within the housing. The tension-relief means 32, which may be of a thermoplastics material, comprises a supporting arm 34 with fixed and mobile clip portions 33, 35 respectively, connected by a flexible web 39. The closure covers 21, 22 have slots 37 to accommodate bars 38 on the foot 36 of the means 32, the foot 36 being disposed between the associated insert and closure cover.

Title: High frequency track circuits for rail-roads interrelated at switches and crossovers
IPC: B61L1/18
Filed: 1969-01-03
Abstract: In a railway signalling system in which different high frequency signals are applied to the track for train detection and for automatic train control and in which the. track circuits are not insulated except at turnout points for diverging track, crossings and cross-overs, the transmission of the train control signal which normally ceases at the turnout point for trains on the divergent track is maintained by a loop conductor connected to the rails of the rails of the divergent track and laid parallel to the rails over the "blind" part of the track. The main track is divided into track circuits AB, CE &c., which are centre fed alternately at frequencies F2, F4 from transmit units 23, 11 &c., via associated bonds 10 &c., and have their extremities defined by tuned receiving bonds 12 &c., coupled to receiver units 31, 13 &c. Each transmit or receive unit is also provided with a transmitter for signals at the train control frequency F1 which is coupled to the track via the associated bond. The arrangement is such that when a train is detected as entering a section of track circuit A, B, C &c., the exit end of the track circuit is fed with a signal at the frequency F1 modulated with signals 15, 30, 50, 80 &c., indicative of the required speed of the train. Assume a train is routed to the diverging track, after passing bond 12 the train control transmitter F1-TR in unit 26 is energized via contacts of the reverse points relay SWR and either track relay CT, for train detection up to the points, or track relay DT for train on entering track circuit D. The train receives the signal before entering track circuit D via the loop 27 which extends circuit D for transmission purposes up to the bond 12.
Patent ES-363454-A1 (ES)
Title: Electronic process controller having a two part error amplifier
IPC: G05B11/42
Filed: 1969-02-08
Abstract: In a closed-loop process control system, D.C. signals of the same polarity, corresponding in magnitude to actual and desired values of a process variable, are applied to a differential amplifier the output of which is applied through a main amplifier to control the process, relatively rapid changes of the process variable being applied through a separate amplifier to the main amplifier. In Fig.1, direct voltage signals which do not reverse in polarity, corresponding to the magnitude of actual and desired values of a process variable, are respectively applied to input terminals 12, 14 of a stabilized differential transistor amplifier 24 the output of which is applied through a high gain, high impedance modulator-amplifier 52 to operate a process controller 56 which maintains the variable at the desired value. A resistance-capacity feedback network 70 associated with amplifier 52 introduces integral and differential components of control. Feedforward of the actual value signal through a transistor amplifier 44 and a capacity 46 ensures that sudden changes of the process variable produce an additional immediate correcting effect at the input of amplifier 52. If a switch 154 is moved to the other position shown, an additional correcting effect as also produced upon sudden change of the desired value. Changeover switches (not shown) are associated with amplifiers 24, 44 so that the sense of control relative to the sense of error may be selected to ensure correction of the error. Control signals greater that a predetermined value render a transistor circuit 164 operative so that the control signals are limited by feedback to the input of amplifier 52 and by back to back rectifiers 166, without the charge on integration condenser 72 increasing or decreasing unduly.

Title: Cleaning device for textile carding machine
IPC: F16C13/00
Filed: 1969-06-03
Abstract: Web impurities, e.g. vegetable waste, nap and short fibres, are removed from a carded web by a cleaning device comprising a driving cylinder 1 and a hollow pressure cylinder 3 resting tangentially thereon. The hollow pressure cylinder 3 is positioned by retaining rollers 4. The retaining rollers 4 are positioned on that side of the plane containing the axes of cylinders 1 and 3 towards which the circumferential portions of the cylinders move directly after parting their line of tangency. The cylinders 1 and 3 and retaining rollers 4 occupy relative positions such that the line of tangency between cylinders 1 and 3 is on the same side as the retaining rollers with respect to the vertical line passing through the axis of the driving cylinder. The hollow pressure cylinder is traversed through its centre by an application bar 5 which is mounted (e.g. by pressure springs 7) on the machine frame so as to be movable transverse to its length. The bar 5 presses on the hollow pressure cylinder 3 exclusively via application rollers 6 which are suspended by elastic means 10. These rollers 6 are placed at intervals along the bar. The application rollers 6 are positioned so that their generatrix of contact with the pressure cylinder 3 is adjacent to the plane containing the axes of cylinders 1 and 3 on that side where the retaining rollers 4 are located. In operation the pressure cylinder 3 and the application bar 5 are able to move, in sequence, away from the driving roller 1.

Title: Disturbing signal detection circuit
IPC: H04B1/16
Filed: 1977-03-30
Abstract: A signal being received and superimposed disturbance pulses are taken from a stage of the receiver where the signal is a periodic wave of constant amplitude or of amplitude varying at rates limited by a moderate modulation band, and the signal so picked up is AC-coupled to a diode clamp circuit, the clamp voltage then being amplified to produce a control output for a blanking gate. The forward voltage of the diode is insufficient to put the transistor of the following amplifier into its conducting condition, so that the transistor conducts only when a disturbance pulse extends beyond the limits of the envelope of the sinusoidal signal. By the use of a phase splitter, two identical clamp circuits may be operated to detect disturbance pulses of opposite polarity, and their outputs may be combined to provide blanking control pulses whenever a disturbance pulse of either polarity appears.
