Patent ES-477679-A1 (ES)
Title: Recuperative coke oven and process for the operation thereof
IPC: C10B21/20
Filed: 1979-02-13
Abstract: A recuperative coke oven includes at least one recuperator chamber arranged below an oven chamber. Hot undergrate firing exhaust gas is passed from the oven through the recuperator chamber. At least one elongated recuperator extends into the recuperator chamber. The recuperator includes an inner tube and a coaxially outer tube. The inner end of the inner tube is open, and the inner end of the outer tube is closed to define an annular chamber between the two tubes. Combustion air to be heated is introduced into the inner tube and passed therethrough. The combustion air then reverses direction and passes through the annular chamber and is thereat heated by the hot exhaust gas passing through the recuperator chamber. The heated combustion air is discharged from the annular chamber and passed to the heating flues of the oven. The length of the recuperator positioned within the recuperator chamber may be adjusted by relative sliding movement of the recuperator, to thereby change the available heat exchange surface of the recuperator and to thus regulate the temperature of the heated combustion air.

Title: A Broadband Reflective Laser Recording and Data Storage Medium with Absorptive Underlayer
IPC: G11B7/26
Filed: 1981-02-13
Abstract: A broadband laser recording and data storage medium for direct read after writing, formed from a photosensitive silver-halide emulsion in four steps. First, a non-saturating actinic radiation exposure is used to create latent images. A normal photographic development is used to produce a medium of gray neutral density. The surface of the remaining silver halide is fogged in a water or alcohol based solution to create a very thin layer of silver precipitating nuclei on the surface. Alternatively a thin layer of nucleating agent for silver precipitation can be incorporated. Finally, a single-step, negative silver diffusion transfer process is used to dissolve the unexposed and undeveloped silver halide, forming silver ion complexes using a monobath containing a silver-halide solvent and a silver reducing agent. These complexes are transported by diffusion transfer to the sites of the silver precipitating nuclei and the filamentary silver on the surface, where the silver complexes are reduced to metallic silver on both the nuclei and the filamentary silver to form a high concentration of non- filamentary silver particles at the surface of a low melting temperature colloid matrix which is highly reflective of light and electrically non- conducting.

Title: Process for applying tin-oxide coatings doped with halogen on glass surfaces by pyrolysis, preferably by fluorine.
IPC: C03C17/23
Filed: 1981-03-13
Abstract: An improved process for coating the surface of a transparent refractory material such as glass with a semi-reflective film of tin oxide by depositing finely divided particles of a pyrolytically decomposable organotin compound on the surface of a substrate which has been heated to a temperature of between about 400 DEG and 650 DEG C. The finely divided organotin compound has a particle size not greater than about 20 microns. Before deposition, the organotin compound is mixed with a predetermined amount of finely divided particles of a compound containing a halogen constituent. Deposition is accomplished by suspending the mixture of both compounds in an anhydrous carrier gas which is projected onto the surface of the substrate. In an alternative process, a single compound containing both tin and halogen constituents is projected onto the surface of the pre-heated substrate by means of the anhydrous carrier gas.

Title: Piston anti-knock back assemblies
IPC: F16D65/18
Filed: 1981-07-09
Abstract: A brake actuator 10 comprising a piston 12 slidably mounted within a cylinder bore 14 comprises an anti- knock back assembly 30 comprising an expanded resilient split ring 32 in frictional contact with a main portion 26 of bore 14 and loosely axially located in an annular groove 28 adjacent a conical head portion 22 of piston 12. The resilient ring 32, when unexpanded, is a sliding fit within the main portion 26 of bore 14, and the resilient ring is provided with abutment spacer means (shaped frustum or leg portion) which, when the ring is placed into contact with an end wall 20 of the cylinder bore 14, the plane of the ring is spaced far enough from wall 20 to allow insertion of the conical head 22 within the ring so as to expand the resilient ring over conical head portion 22 until it snaps into position in said annular groove 28. This gives frictional grip of ring 32 with bore 26, and ring also acts to adjust for friction surface wear to provide constant retraction distance (w-t).

Patent ES-8603050-A1 (ES)
Title: Timed flow control valve assembly.
IPC: G05D7/01
Filed: 1984-08-14
Abstract: Water from a circulation pump enters a control chamber (36) where a truncated conical valve (42), movable between a main outlet port (44) and a sec. outlet port (38), divides the flow between the main outlet (14) to a return conduit and the sec. outlet (16) to a pool wall and floor cleaner. The valve (42) is biased by a regulator spring (64) between a control piston (56) and latch spool (66). - Flow through the sec. outlet (16) at cleaner-operative pressure operates a water-turbine flowmeter (76) with magnets (90) rotating between pole pieces (94) of an armature coil (96). On completion of cleaning, the timer (98) triggers a solenoid (106) to release the latch (72). A weaker return spring (130) allows the spool (66) and piston (56) to move and operate the valve (42), whose disc (40) closes the sec. port (38). (2/8) USAB- US4522221 A Upon elapse of a predetemined time interval, a timer assembly responsive to the secondary outlet flow triggers an alteration in ths pring bias acting on the regulator valve to permit fluid pressure at the valve inlet to shift the regulator valve to a position closing the secondary outlet and fully opening the primary outlet for the remaining time of a fluid flow cycle. When fluid flow through the valve assembly is halted, a return spring resets the regulator valve to its initial state. - The primary outlet of the valve assembly is coupled to a return conduit for recycling filtered water to the swimming pool, and the secondary outlet is coupled to a water-powered in-the-pool cleaning device. During a normal filtration cycle, the valve assembly initially supplies water to the cleaning device at a predetermined minimum pressure for a selected time interval and then automatically switches state to halt operation of the cleaning device and to recirculate filtered water to the pool through the return conduit.
