Patent ES-293027-A1 (ES)
Title: High speed tire
IPC: B60C9/26
Filed: 1963-10-30
Abstract: A pneumatic tyre for a vehicle operating at high speeds comprises a carcass 10 constituted by one or more layers of parallel cords, cables, tapes or the like arranged in radial planes of the tyre, a tread 13 reinforced by means of one or more fabric layers embedded therein, and a circumferentially inextensible breaker 12 located between the tread and the carcass. This breaker 12 has a circumferential length such that it prevents radial expansion of the carcass. The elasticity of the tread may be varied in a radial direction by varying! the spacing between the reinforcing layers or by varying the angles made with the midcircumferential plane by parallel cords constituting these layers. In one embodiment, Fig. 5 (not shown), the radially outermost reinforcing layer (19) extends into circumferential ribs provided on the tread surface. In other embodiments the reinforcing layers extend radially inwards around the edges of the breaker 12 towards the carcass or continue through the tyre sidewalls to the bead regions. Alternatively, the reinforcing layers may be formed by folding back the edges of two or more of the layers constituting the breaker 12. The reinforcing layers are formed with nylon, rayon, polyester or glass fibres or steel, aluminium or other metallic cords.

Patent ES-304816-A1 (ES)
Title: Improvements in or relating to liquid fuel dispensing apparatus
IPC: G01V3/10
Filed: 1964-10-09
Abstract: Liquid fuel dispensing apparatus includes a dispensing nozzle provided with electrical detector means operative to permit or prevent flow of fuel according to whether or not the nozzle is inserted in the metallic filler tube of a fuel tank. The detector means comprises an exciter coil energized with alternating current coupled with a detector coil and a compensator coil, the degree of coupling between the exciter and detector coils being reduced when the nozzle is inserted in the filler tube and the e.m,f, in the detector coil being thus reduced. If the nozzle is of aluminium, a lagging e.m.f. induced in the detector coil results in a phase change in the detector coil current which can be compared with a standard if the voltage reduction is insufficient. To enable the detecting means to distinguish between the nozzle boot of the dispensing apparatus and the filler tube the nozzle boot may be provided with a pick-up coil in which an e.m.f. is induced by the exciter coil to prevent operation of the petrol switch relay.

Title: Process for Finishing Leather
IPC: C14C11/00
Filed: 1966-09-13
Abstract: In a process for finishing leather, an aqueous solution or dispersion of a non-thermoplastic product resulting from the condensation of an alkylene imine with urea or a urea derivative and functioning as a non-thermoplastic binder, is applied to a surface of the leather, which surface is subsequently hardened by treatment, e.g. spraying, with an aqueous formaldehyde solution e.g. containing between 5 and 30%, by weight, of formaldehyde and having a #H between 3À5 and 6 5. The aqeuous formaldehyde may contain a water-soluble chromium salt such as chromium sulphate. The condensation product may be mixed with one or more than one other non-thermoplastic binder selected from: oxethylized casein, albumin and synthetic polymers, e.g. derived from styrene and maleic ankydride, or from acrylonitrile. The weight ratio of the condensation product to the other non-thermoplastic binder or binders may be between 1:2 and 1:5. Alternatively, i.e. when hot-ironing forms part of the finishing process, the condensation product may be mixed with a thermoplastic binder, e. g. a copolymer of butyl acrylate, vinyl acetate and vinyl chloride respectively in the proportion of 50:30:20, by weight, and, if desired, with one or more of the above - mentioned other non-thermoplastic binders. The alkylene imine may be ethylene or propylene imine or a dito hexa-meric polymer thereof. The urea derivative may be ethyl, butyl, phenyl or benzyl urea. The condensation product may be prepared by condensing one mole of urea or urea derivative with 0À5 mole to 4 moles of the alkylene imine. The aqueous solution or dispersion of the condensation product may contain ammonia or mono-, di- or triethanol amine, and one or more of the following substances: a coating colour, e.g. iron oxide red, a brightening agent, a softening agent, e.g. sulphonized castor oil. The aqueous solution or dispersion may be applied by brush, plush-board or spray-pistol. After the form aldehyde hardening treatment, the leather is dried and glazed or pressed, e.g. in an ironing press, at 70 C. and 150 atmospheres gauge pressure.

Patent ES-348720-A1 (ES)
Title: Time optimal servo control system
IPC: H02P8/00
Filed: 1967-12-28
Abstract: A load is driven to a target position by an electric (e. g. stepping) motor through a deceleration zone which is bounded by the optimal deceleration trajectory 222 and a predetermined "corrective speed level" 233, which intersects 222 at 223, logic means operating to decelerate the motor when its speed is above the level 233 and to accelerate it when it is below. The system is such that the stop command is normally given 40 steps before the target position if the motor has reached full speed 220 it will automatically decelerate along trajectory 222, but if it was still accelerating, 230, it at first decelerates along 232. If this continued the load would stop short, so when predetermined speed 233 is reached the motor is alternatively accelerated and decelerated so that the average speed is constant until the main trajectory is reached at 223 and this is followed to the target position 229. There are preferably three predetermined speed levels 233, 235, 236 at which the control can operate. In the complete system Fig. 1 a desired motion is set up in digital form by a processor 1 in a clockwise 3 or counterclockwise binary counter 7, the opposite one of which receives pulses from the motor corresponding to distance travelled by the load. The difference between the counters is detected by a comparator 5 which energizes lines 36 or 37 to instigate motion in the appropiate direction, and also one of these lines 31...34 according to the magnitude of the difference. These lines are connected to AND gates in a logic deceleration control system 10, the other inputs to the gates being on lines 26... 29 according to the motor speed, as determined by another logic circuit 9 in which pulses from the motor are passed through timing circuits. The output of 10 on line 45 is a stop command when the motor is required to decelerate. For high speed motion the controller 16 energizes the motor at two step intervals, but as the load nears the target position the circuit 10, over output line 45, causes single step control. This is also used in the event of an overshoot. The motor and its controller are described in Specification 1,105, 598 (Division H2A).
