Patent ES-321704-A1 (ES)
Title: Radio-electric system for vehicle identification
IPC: H01Q3/44
Filed: 1966-01-13
Abstract: In an interrogator-responded system for identifying moving, e.g., rail vehicles, the responder apparatus on the vehicle is energized by the interrogation signal when the vehicle is opposite the interrogating track apparatus. Responder apparatus.-A U.H.F. squarewave-modulated interrogation pulse is received by aerial 11, demodulated by rectifier 12, limited in amplitude by Zener diode 13 and applied to a delay line 14 having a delay equal to the pulse duration. The input and output of the delay line are connected via rectifiers 15 to the supply input of four different frequency transmitters 18 and thus enable these transmitters to be triggered on during a period equal to twice the delay time. The identification number to be transmitted, comprising twelve decimal digits, is set out by detachable plugs on a matrix board 16 comprising twelve columns and ten rows. The columns are energized in sequence by the pulses generated in the output windings of the delay line and each pulse is routed in dependance on the plug position to one of ten inputs of an encoder 17. The encoder in dependance on a predetermined code triggers one or more of the transmitters 18 into oscillation and the identifying numbers are thus transmitted in sequence to the interrogator 1. Interrogator.-The response signals are applied via receivers 24 to the input of a decoder unit 25 which energizes its output terminals and hence the rows of display matrix 26 in a sequence dependant on the identifying number. The square wave generator 26 which supplies the interrogating square pulse for modulating the U.H.F. generator 22 also supplies the pulse to a delay line 114 identical to that carried in the responder apparatus whereby the columns of the display matrix are energized at the same time as those of the responder matrix board. Each junction of the matrix is provided with a coincidence circuit, a memory and display lamp and these record the identification number.

Patent ES-341653-A1 (ES)
Title: A method and a device for developing Crimps in Conjugate Filament Yarn
IPC: D01D5/32
Filed: 1967-06-10
Abstract: Crimps are developed in conjugate filament yarn by heating the yarn by passage through a tube heater, a section through which is a closed curve, located between feed rollers and withdrawal rollers (not shown), said tube heater having at least two bends so that the running yarn is contacted with the inner wall of the tube at the points of bending, and undergoes at least two changes of direction within the tube, the ratio V 1 /V 2 of feed velocity (V 1 ) to withdrawal velocity (V 2 ) being at least 1-2. The tube heater may be bent in either a plane or in three dimensions, and in either a regular shape as in Figs. 2 to 6, or in an irregular shape, as in Fig. 7. To minimize friction the inner surface of the tube should be finished as smoothly as possible, for example an aventurine finish may be effected by chemical polishing. Suitably, the degree of roughness in the inner surface of the tube is preferably IS to 10S, preferably 3S to 5S, where S is the average value of the height of uneveness of the uneven surface H when measured 10 times, and expressed in microns. The tube may be heated electrically, either applying an electric current to the tube itself to generate heat or by high frequency heating, or by the use of a heating medium such as a gas, liquid or solid. The tube may be surrounded by a heating member, which in turn is surrounded by an insulating member. The use of the apparatus enables improved crimped filament yarn to be obtained, having little uneveness of crimp, at a higher speed than by conventional methods. In example 1, a conjugate filament comprises a nylon-6 component, and a 90 : 10 copolymer of nylon-6 and polyhexamethylene isophthalamide, in side-by-side relationship. After melt spinning, the filament is wound and drawn to 3À69 times its original length at room temperature. This drawn yarn is passed through a stainless steel tube having an inner diameter of two mm., a degree of roughness of the inner surface of 3S and a length 50 cms. held at 175 C. and using a feed ratio V 1 /V 2 of 1-45, to develop crimps, using tubes having 2 to 5 contact points, and feed velocities of 274 to 290 m. per min. Example 2 is similar except that a feed velocity of 200 m. per min. is used.

Title: Production of POlymeric Foam.
IPC: B29B7/00
Filed: 1967-07-15
Abstract: Polymeric foam with a flat upper surface is moulded by foaming on a conveyer belt, the sides of which move at the same rate as the conveyer and increase in height at the same rate as the foam rises to keep the top surface of the foam flat. The apparatus comprises a horizontal conveyer 1 lined with paper from reel 4. Paper from reels 5 moves along each sidewall 3 to form a lining. Paper from reels 6 passed inside the other lining, to form a second lining adhesion to the first lining being by adhesive supplied at 7. The mixture to be foamed is supplied through nozzle 7. On reaching gripper 8 (where the foaming starts), the inner layer of paper 6 is gripped and pulled off from lining 5 breaking the adhesive bond. This paper 6 is attached to forceps 9 on conveyer 10 and is raised at the same rate as the foam rises keeping the top of the foam plane. The paper 6 is then released and continues along the side of the foam block. Conveyer 9 can be moved along the line of conveyer 1 and also raised and lowered to accommodate different rates of foaming and sizes of the finished foam.

Title: Electric circuit breaker with special arc extinguishing structure
IPC: H01H71/24
Filed: 1967-10-27
Abstract: Two fixed contacts 14, 15 arranged to be bridged by a moving contact 30, are supplied through conductors 23, 24 which lie parallel to a line joining the fixed contacts and which are connected to the fixed contacts as shown so that the current flows in the same direction in the two conductors 23, 24 and in the opposite direction in an arc joining the two fixed contacts so that such an arc is driven away from the conductors on to arc runners 18, 19. The moving contact is U-shaped, the base of the U lying parallel to the conductors 23, 24 and on the opposite side thereof to the contacts 14, 15 so that upon overload the moving contact is driven to the open position by the electrodynamic repulsion. The contact 30 is coupled through an overcentre mechanism to a pivoted handle which is used to reset or open the contacts manually. The contacts are located in an insulating arc-chute whose inner walls are composed of an acetal resin material such as polyoxymethylene. In an alternative arrangement (Fig. 7, not shown) a straight bridging contact is used and the electrodynamic repulsion then serves to hold the contacts firmly closed.
