Patent ES-293978-A1 (ES)
Title: Check valve for use with a master cylinder
IPC: B60T11/22
Filed: 1963-11-28
Abstract: A liquid pressure master cylinder 10 for vehicle brake systems is provided with a valve 31 to control the flow of liquid through a pressure outlet 15, the valve comprising a body member 41 which, under the pressure of a spring 44, is adapted to make sealing engagement with a seat around the pressure outlet 15 and the concave arcuate surface, the body member of the valve is formed with an orifice 51 which is controlled by a resilient blade-like member 53 so that the member 53 is displaced by the liquid flowing out of the master cylinder through the pressure outlet. As shown in Figs. 2 and 3 the valve body 41 has an interrupted flange 42 to guide it in the master cylinder barrel 10. On brake release the blade-like member 53 is urged against the peripheral surface of the recess 46 by liquid returning into the master cylinder so that liquid can enter the master cylinder only so long as the pressure is sufficient to compress the spring 44 of the master cylinder and move the valve body 41 away from the end of the cylinder. On brake application outward flow of liquid displaces the blade-like member 53 away from the peripheral wall of the recess and allows the liquid to flow through the orifice 51. The provision of an orifice in the peripheral wall of the recesses of the valve body 41 causes the liquid to tend to flow in a circular path around the valve body to effect scavenging of air from the master cylinder. A small hole 54 in the centre of the body 41 enables final equalisation of pressure to take place.

Title: Improvements in and relating to a control system for marine engine plants comprising a plurality of internal combustion engines
IPC: B63H21/22
Filed: 1964-01-09
Abstract: A control system for marine engine plants having a plurality of internal combustion engines 11, 12, Fig.1, each of which is connected to an input shaft 15, 16 of a common gear 17 through a releasable clutch 13,14, the output shaft 18 of the gear driving a variable pitch propeller, comprises a selector member 23 for rendering one or more of the engines inoperative and a manoeuvring member 22 for adjusting the power output of the plant, the manoeuvring member being connected to the governor inputs 33, 34, Fig. 2, through a transmission whose mechanical advantage is determined by the position of the selector member 23. The input shafts 33, 34 determining the speed settings of the governors, are coupled to a common shaft 49 by torsion couplings 50 and are separately connected by cables 24, 26 Fig. 8 to the ends of levers 86 having followers 85 engaged by slots 84 in cam discs 83 operated through a shaft 73 from the selector member 23 initial movement in one direction of the selector member starts one engine while initial rotation in the opposite direction starts the other. Continued rotation in either direction, however, causes both engines to be operative. Bevel gears 90, 91, a shaft 92, a cam 93, Fig.7, and a linkage 96, 98, 81 shift a pin 80 in a slot 79 of a bell-crank lever 76 forming part of the transmission between the manoeuvring member 22 and the governor input shafts 33, 34 so that the latter receive only half the adjustment when both engines are running. The link 81 is connected by a cable 26 and a lever 48 to the shaft 49 and by the lever 76 and a cam 74 to a shaft 72 on which the manoeuvring member 22 is mounted. A valve 64 controlling a servomotor 19 for altering the pitch of the propeller is connected by a lever 56 to a shaft 52 coupled by dogs 54 to the governor output shafts 35, 36 and by a lever 59 to the cable 25 and hence the shaft 49 while a switch 112 operated by the edge of the cam 74 causes pitch reversal. The shafts 72, 73 carry discs 101, 102 with pawls 106 and notched rims which interengage to prevent the selector handle 23 from rendering one or both engines inoperative before the manoeuvring handle 22 has been returned to idling position. Whether one or both engines are running, the handle 22 can be moved freely to regulate speed, the rim of the disc 101 passing through a notch 105. When the handle 22 is in the position corresponding to half output of the plant, a notch 104 is opposite the periphery of the disc 102 to permit the selector member 23 to be turned to start the second engine.

In a preferred form, there are two groups the front upper rollers of each group are arranged in pairs joined by a common shaft 28 or 75 and supported in a tilting arm 32 or 76, while the corresponding lower rollers 24 or 72 are continuous throughout the machine. Connected to each arm 32 or 76 is a hook 46 or 86 embracing a tie-bar 48, 88 connected by a threaded, adjustable connector 49, 89 to a loading-spring 50, 90. The loading at individual groups can be adjusted by turning the connector 49, 89 the loading of corresponding groups at a number of spinning positions can also be simultaneously adjusted. To this end, the springs are each connected to one arm of a bell-crank pivoted at 94, Fig. 2, to a fixed part. The other arm of each bell crank of the corresponding groups at a number of spinning positions is connected to a common bar 100 mounted to slide in fixed guides, e.g. 102, Fig. 1, one end of the bar is threaded into a nut 106 integral with a worm meshing a wheel which can be rotated by a handle applied at 116, so that the position of the bar, and hence the loading of all the upper rollers can be varied, markings 105 indicating the value of the loading. Each group comprises a double apron 16, 18 or 56, 58. The aprons 16, 18 are each trained around a roller and a nose bar: of the aprons 46, 58 the lower one is trained around rollers 52, 56, is tensioned by a roller 64, and supported by a plate 62, while the upper one is trained around a roller 54 and a nose-bar 66 tensioned by a rod 68 pivoted on roller 54 and acted on by a spring 70. The front upper rollers in each group are caused by a hook 30 holding the neck between the twin pair by a ball-catch. Fig. 3, not shown. The hook 46 or 86 supporting the tie-bar 48 or 88 is carried by a sleeve eccentrically mounted in the corresponding tilting-arm and adapted to be rotated by a handle 44 to lower the hook and relieve the loading so that the lifting-arm can be raised.
Patent ES-337101-A1 (ES)
Title: Method of temporarily deforming hydrophilic contact lenses,grinding and polishing
IPC: G02C7/04
Filed: 1967-02-21
Abstract: A method of final grinding and polishing of a hydrophilic contact lens comprises deforming the lens at a temperature higher than its softening temperature by pressing it into a defined surface, and subjecting it to a final grinding and polishing after cooling it in its deformed state and while in such state. The lens is moulded from a monomer mixture of glycolmonomethacrylate, glycoldimethacrylate and isopropylpercarbonate and is washed in distilled water and dried. A rubber stopper heated to 150 C. is used to press the lens on to a ground glass plate also heated to 150 C. As the lens softens it flattens on to the plate and upon cooling returns the flat shape so that, upon removal from the plate, it can be ground by a planar grinding plate covered with woollen fabric impregnated with eerie oxide in xylene. The lens may be relaxed to its initial moulded shape by reheating or by contact with water or physiologic solution. In another example, the lens is deformed to a spherical or cylindrical shape for final grinding and polishing. The lens may be deformed to a second shape for treatment of its other surface.

Title: Method and apparatus for producing a voluminous yarn with uniformly spaced bindings
IPC: D02G1/16
Filed: 1967-03-15
Abstract: A multifilment, nylon yarn (which may have been compressively crimped) has uniform, regularly occurring constrictions formed along the length thereof by imposing a compulsory oscillation on the travelling yarn between two fixed points, defined by thread guides, under the action of a gas stream flowing perpendicularly to the direction of travel of the yarn and through which stream the yarn travels twice in each oscillation period. The yarn is fed to the zone between the guides at a speed 5-50%. higher than withdrawal therefrom. In the blowing device shown, a compressed air supply pipe 11 terminates in a "mouthpiece" 13 having a nozzle 12 facing a resonance plate 14. A sleeve 15 comprises slots 16 constituting the thread guides and bores 18 which prevent any back pressure of air in the space between plate 14 and nozzle 12 thereby, making possible the yarn oscillation.

Title: A process for coating metal surfaces
IPC: B05D7/14
Filed: 1967-04-03
Abstract: A process for coating metal surfaces comprises applying particles of a thermoplastic material at least substantially entirely in the form of cylinders of maximum diameter 0.05 to 0.4 millimetres and length 0.05 to 0.4 millimetres' to the surface of the metal and sintering them to form a coating. The particles can be made by cutting mono-filaments of the thermoplastic material. Suitable thermoplastic materials that may be used are high-pressure, normal-pressure and medium-pressure polyethylene, polypropylene, cellulose acetobutarate, hard and soft polyvinyl chloride, chlorinated polyethers, polyamines such as polycaproelactam, polyenanthlactam, polyoapryl lactam, polyundecalactam, polyhexamethylenesebicinate, polyhexamethylene adipite and copolyamides from the known monomers, acrylonitrile-butadiene-styrene co-polymers. The micro granular material may contain various additives such as dyestuffs, delustering agents, melting flow agents, dispersing agents, antistatics, light and heat stabilisers, ageing resistors, adhesion facilitating agents, plasticizers and agents for reducing the surface tension of a melt of the thermoplastics. The process may be used for coating metal sheets, plates, rods or tapes. The metal may be heated to the fusion temperature of the thermoplastic before the particles are applied to it, for example by dipping the metal into a zone of stationary or whirled-up particles or by sprinkling or rolling the particles onto it. The metal surface should be degreased for example by sand blasting or chemical methods, before coating.
