Patent ES-344210-A1 (ES)
Title: Side washer for worm and roller steering gears
IPC: B62D3/10
Filed: 1967-08-18
Abstract: A valve, for automatically venting a storage vessel 11 when the pressure therein is either below or above atmospheric pressure, includes a two-part valve casing 10 secured to a pipe section 12 which is welded to the vessel 11, the upper part of the casing, which is in the form of a dome 18, carrying a pressure-responsive pilot valve 34, and the lower part of the casing, formed as an open support from a series of spaced rib members 13E, being secured, together with a plate 13 having an upstanding cylindrical portion 13C, to the pipe section 12. The portion 13C constitutes a valve seat engageable by a valve closure member 20 which is carried by a diaphragm 17 secured between the two parts of the casing 10. A tapered pipe section 24 is secured to the closure member 20 and is telescopically received within a similar pipe section 32 secured to the pilot valve. In operation, upon the vessel pressure exceeding atmospheric pressure, a similar rise in pressure occurs in a chamber 26, defined by the dome 18 and diaphragm 17 and this pressure acts on the pilot valve closure member 40 tending to raise it from its seat. Upon this occurring, flow from the vessel 11 takes place through pipes 24, 32 and openings 44C to atmosphere, and flow from chamber 26 takes place through openings 38A and 44C to atmosphere, the first flow, on account of the tapered portions 24A and 32A of the pipes 24, 32, developing a velocity head which enhances exhaustion of chamber 26, serves to maintain member 40 unseated and so permits member 20 to become unseated. Upon the vessel pressure falling below atmospheric pressure, the pressure differential across the diaphragm becomes such that atmospheric pressure acting on the underside of the diaphragm raises member 20 from its seat so allowing the vessel pressure to be increased. Should the diaphragm become ruptured so preventing member 20 from unseating, then if the pressure built up in chamber 26 becomes sufficient to raise a disc-like closure member 28 from its seat, on to which it is held by a magnet 30 or spring (50, Fig. 2, not shown), a free transfer of pressure takes place through apertures 20C formed in the closure member 20.
Patent ES-344698-A1 (ES)
Title: Supercharged internal combustion piston engine
IPC: F02B37/14
Filed: 1967-09-02
Abstract: In an I. C. engine a hydraulic positive displacement motor 10, Fig. 3 is coupled directly to the shaft 4 of an exhaust gas turbine-driven supercharger unit 2 by a non-releasable coupling 8 and a hydraulic pressure line 14 and an air line 43 are each connectable to the hydraulic motor inlet. Operation: Oil is delivered by an engine driven or electric motor driven pump 13 from a tank 17 through a transfer pump 30 to the hydraulic line 14. Pump 30 may supply the engine lubrication system through feed and return lines 31, 35. The connection of the hydraulic feed line 14, and the hydraulic return line 52 to hydraulic motor 10 is controlled by a spring-loaded spool valve 51 which moves in response to the air pressure existing in reservoir 7. At lower engine outputs the apparatus is in the position shown when the supercharger 2 derives additional power from the hydraulic motor 10 which discharges into line 52. During full load operation the supercharger 2 receives sufficient power from the engine exhaust gases and also drives the hydraulic motor 10 which then acts as a pump. The increased pressure in reservoir 7 acts on spool valve 51 which is moved to a position admitting only oil-laden air from the engine crankcase through line 43 to the hydraulic motor 10, which is thereby cooled, air being discharged from the hydraulic motor via line 53 to tank 17. In modifications valve 50 may be operated electromagnetically and line 52 may lead into the engine crank-case. When the pressure in reservoir 7 rises beyond a predetermined value a valve 34 is progressively opened by a servomotor 37 in response to the pressure rise communicated through line 38 to by-pass the oil delivery back to tank 17. Alternatively valve 34 is opened in dependence upon crank-shaft or supercharger speed or the pressure in line 14. In another embodiment the hydraulic and air return lines 52, 53 are replaced by a single hydraulic and/or air return line (15, Fig.2 not shown) which is not controlled by the spool valve and discharges directly into tank 17. In a further embodiment the spool valve 50 is omitted, the pump 13 feeds the hydraulic motor 10 directly and the air line 6 and hydraulic line 14 are interconnected by a relief valve (22, Fig.1 not shown). During full-load operation the pressure drops in the hydraulic line 14 and the increased pressure in line 6 causes the relief valve (22) to open thereby admitting air through the downstream part of the hydraulic line, to the hydraulic motor 4. When the engine slows down the pressure in line 6 drops, valve (22) closes and the motor 10 recommences to drive.

Title: Method of cleaning oil-contaminated particulate materials
IPC: C02F1/68
Filed: 1968-04-24
Abstract: A method comprises applying to the surface of a mass of particulate matter a natural or synthetic rubber latex whereby a protective layer of coherent particles of particulate matter is formed, exposing the layer to oil whereby it becomes at least partially impregnated with oil and, susequent to the exposure to oil, removing the oil-impregnated layer. By employing the method there is a reduction in the contamination and impregnation of the mass which would otherwise occur by exposure to oil. The particulate matter specified is sand and hence the present invention is particularly suitable for treating beaches. The latex may contain 5- 65% by weight solids and is preferably applied at a rate of 1-12 oz. of dry rubber per square yard of sand. The synthetic rubber latex is preferably a butadiene homopolymer, a butadiene copolymer wherein the comonomer may be styrene, acrylonitrile, isobutylene, acrylic acid and acrylates, an ethylene-propylene copolymer or butyl rubber. The oil may be a heavy fuel oil.

Title: Diverter valve means and method
IPC: F16K31/68
Filed: 1968-09-25
Abstract: In a diverter valve assembly 10 with fuel outlets 16 and 18 for a bake burner 17 and a broil burner 19, when a control 12 is turned from " bake " to " boil," in addition to fuel being supplied to an inlet 15 a pilot burner 21 is ignited and a flame sensor 66 thereat causes a lever 38 to pivot at 46, 47 on a plate 48 in the valve housing 10 from its rest position, Fig. 1, when a valve 25, 26 supplies fuel to the bake burner, and a similar valve 27, 28 for the broil burner is shut, through a position with both valves shut and then to a position where only valve 27, 28 is open, Figs. 3 and 4 (not shown). Each valve closure member 26, 28 is urged to close by a spring 36, 37 respectively, acting between the housing and a shoulder end of the stem 30 of each closure member. The end of the lever 38 remote from the pivot is bifurcated and engages the stems 30 of the closure members so that when the lever pivots there is lost motion the closure of one valve and the opening of the other. A spring 58 between tangs on the lever 38 and the plate 48 biases the lever to its rest position and is disposed to give an " over dead centre" operation, wherein the valves close slowly but open with a snap action. The effective pivotal point of the lever is adjusted by a screw 55 in the housing bearing on a tang 53 of plate 48. The flame sensor is a fluid containing bulb serving when heated to displace a wall 67 carrying a ball 69 which bears on a flat end portion 41 of the lever 38 to the right of the pivot 46, 47 as seen in Fig. 1. The valve members are guided in the housing by guide stems 34 having free ball ends 33 to allow rocking and permit seating of the valve member.

Patent ES-412073-A1 (ES)
Title: Childproof actuator cap for aerosol and like dispensing devices
IPC: B65D83/16
Filed: 1973-02-26
Abstract: This invention provides a childproof actuator cap for small hand-held dispensers of the type wherein a cap body in the form of an inverted shell has a central bore which slidably carries an actuator button connected with the valve stem or plunger of the dispenser. The cap body has in its rear wall a deep, finger-receivable notch which locates the user's finger in the proper position for depressing the actuator button. A guard piece or cover member is carried by the cap body and overlies the actuator button, thereby to normally shield the same and prevent its actuation. The guard piece is hingedly connected to the front wall of the cap, and is further connected separably to the back wall of the cap by a clasp means which normally is so arranged that an infant or small child cannot readily comprehend the movements necessary to undue the clasp. The entire actuator cap presents generally a closed appearance, such that a person who would operate the dispenser requires knownledge or judgement gained from experience, indicating to him beforehand that the guard piece must be shifted to uncover the actuator button. This knowledge is needed, in addition to any dexterity normally required to separate the clasp. For a person who is properly informed, the operation of the dispenser is relatively simple. Such person merely lifts the back end of the guard piece to unclasp it, whereupon the piece can be swung upward to provide access to the actuator button. The informed user then merely holds the dispenser in the usual manner with the index finger under the raised, hinged guard piece and on the button, and thereafter depresses the latter to discharge the contents. While such operation is seemingly simple, it cannot be readily effected by a small child or infant who lacks the knowledge that first the guard piece must be raised to uncover the actuator button, and second that raising of the guard piece requires an unlatching or opening of a clasp by which the guard piece is secured in place.
