Title: Heating apparatus
IPC: D02G1/02
Filed: 1965-05-26
Abstract: In a false-twist crimping apparatus, a plurality of synthetic yarns is heated by oblique travel across and in contact with the surface of a heater comprising hollow bodies interconnected at their ends to form a closed circuit for a hot liquid circulated therethrough at high velocity and with turbulent flow such that the same temperature is maintained throughout the bodies. Electrical heating and/ or control elements are disposed within the bodies and in the flow path.

Title: Crimping apparatus
IPC: D02G1/12
Filed: 1968-02-16
Abstract: A crimped yarn is produced in one continuous process by drawing synthetic filaments issuing from a spinneret, and then crimping the filaments in a stuffer box. The box comprises fixed back and side walls, and a front wall formed by a door hinged to the back wall and having a yarn guide which when the door is closed is disposed at the entry side of the feed rolls of the box. The door is kept closed by an electromagnet, the circuit of which can be opened by a handle on the door. The door has an adjustably weighted flap which closes the exit of the box. The box may have two compression chambers each with its own closure flap. Before the crimping the filaments may be heated in addition to the heating generated by the drawing, and after the crimping the yarn may be wound, or set.

Patent ES-354676-A1 (ES)
Title: Frequency Synthesizer Apparatus for the Transmission of Speed Data to Trains
Inventor: JAUQUET CHRISTIAN
IPC: B61L23/16
Filed: 1968-06-04
Abstract: A track loop K in advance of a signal having aspects R (red), J (yellow) and V (green) is fed, in dependence on the aspect, with a signal having a frequency which is indicative of the train speed required at the signal. When the section following the signal is occupied relay V releases operating aspect R and supplying a signal to gate P 00 , when one section following the signal is free relay V picks up energizing aspect J (yellow) and supplying a signal to gate P 16 , when two sections are free relay A also picks up energizing aspect V (green) and supplying a signal to gate P 18 and when three or more sections are clear relay P picks up supplying a signal to gate P 15 . The gates are associated with oscillators F 00 , F 16 , F 18 , and F 20 and filters f 00 , f 16 , f 18 and f 20 which respectively generate and pass signals at frequencies indicative of speeds at the signal of 0,160 km./h., 180 km./h. and 200 km./h. Assume aspect J (yellow) is showing, gate P 16 is opened and the oscillator F 16 signal is applied via the gate, filter f 16 , amplifiers AS and AP to the track loop K, whereby a train entering the loop section picks up the signal and regulates its speed to 160 km./h. at the signal. In addition the output of amplifier AP supplies the signal to a comparator C which if the signal is between preset limits maintains gate S open so that the oscillators may be energized via unit O and amplifier AA. Switch B which by-passes gate S, allows the apparatus to be switched on initially.

In another embodiment, the ring is of quadrilobate instead of V cross-section and both the skirt portions make contact if desired, the skirt portions may be provided with beads which engage in corresponding grooves.
Patent ES-376779-A1 (ES)
Title: Coin receiving and reimbursing apparatus
IPC: G07F1/04
Filed: 1970-02-12
Abstract: Coins inserted into the apparatus fall into the lower part of an arcuate storage channel 17 formed on a vertical plate 1, and periodically are pushed towards a hole in the plate at the top of the channel by a stud 33 on a rotating arm 34, a deflector 36 situated in the hole diverting the coins so that they fall into a coin delivery tube 5. The shaft 35 may be driven by an electric motor energized each time, for example, an article, such as a ticket is vended. If it is required to collect more than one denomination of coin several plates may be used (Fig. 2, not shown) and in this case the delivery tubes are preferably made integral with a magazine (9). The front of the plate may also carry a coin duct 13 which may embody a suitable coin selection mechanism. A coin rejected by the mechanism falls in the direction of arrow f 1 into a passage 14 leading to a refund cup 15. Coins accepted by the mechanism proceed along the duct and fall into the orifice 16 of the storage channel. At this inlet there may be a photo-cell device 21 to count the number of coins received, and associated with it is a pivoting lever 22 adapted so that a nose 24 temporarily closes the channel after the passage of a coin, thereby diverting the second of two coins inserted in close succession and hence preventing the erroneous transmission of only one pulse from the photo-cell. This lever also diverts further coins when the storage channel is full. A lower portion of the channel 17 may be replaced by a segment 26 pivoted at 27 to provide a coin return mechanism. The segment 26 is moved to the dotted.line position by activation of an electric motor which drives a shaft 30 carrying a cam 28, allowing the coins in the channel to fall, guided by a member 32, into the refund cup 15. A device may be provided to divert coins to a cash box when the tube 5 is not in position comprising an arm 39 pivoted at 41 and having a blade 38 pivotally mounted on it. When the tube is not in position the blade diverts coins in the direction of arrow f 4 on to a guide 37 and into a channel leading to the cash-box, see also Fig. 4 (not reproduced). The tube when inserted co-operates with a nose 42 on the arm 39 and removes the blade. When the tube is full, further coins are also directed to the cash-box by the member 37. When change is required a solenoid 43 is activated and an armature 44 acts upon a pawl 45, reciprocated by mechanism 46, forcing the hook-shaped end of the pawl 45a into engagement with a finger 48 on a sliding plate 49, which is normally urged to close the lower end of tube 5 by springs 51. Each reciprocation of the plate 49 corresponds to one coin being given in change and is detected by a photo-cell device 52. When the number of coins paid back reaches the desired value the solenoid 43 is deactivated disengaging the pawl 45. Another photo-cell device (53, 56) may be provided at the lower end of tube 5 to check that the number of coins does not fall below a certain minimum value, and this may activate a signal warning the user to insert the correct amount.

Patent ES-430205-A1 (ES)
Title: Line protector for a communication circuit
IPC: H01H85/44
Filed: 1974-09-19
Abstract: A line protector for a communications circuit provides overvoltage and overcurrent protection. The overvoltage protection is effected through a carbon electrode or gas tube unit that provides an arc gap from the line to ground. For overcurrent protection a fusible element melts and a volute spring presses the overvoltage unit toward the base of the protector and forms a direct metallic circuit from the line to ground, bypassing the electrodes of the unit. A shunt houses the overvoltage protector unit and cooperates with the volute spring to carry the overcurrent to ground. A heat coil may be provided in the line circuit and located between the overvoltage protective unit and the base so as to keep the length of the line current path within the protector to a minimum. The various sub-assemblies of the protector are positioned in line and substantially coaxial within the protector housing.
