Patent ES-341906-A1 (ES)
Title: Infra-red heater
IPC: G03G15/20
Filed: 1967-06-16
Abstract: An infra-red lamp comprises a tubular quartz envelope containing a coiled tungsten filament in direct contact with the wall of the envelope. The filament operates at a temperature between 1900 and 2100 F. and has a radiation peak at a wavelength around 2À2 Á which is readily transmitted by the envelope. The envelope, which absorbs infra-red radiation at longer wavelengths and is also conductively heated by the filament, reaches a temperature between 1100 and 1200 F. and itself radiates with a peak around 3À4 Á. The resultant radiation of the lamp therefore has a high intensity over a broad band of the infra-red spectrum. The lamp is designed for fusing xerographic toning powder to white bond paper, the powder and the paper having different heat absorptive qualities.

Title: A process for embossing latex foam
IPC: C08J7/02
Filed: 1967-11-10
Abstract: Latex foam is embossed by applying to the cured and dried foam a volatile plasticizer for the foam and embossing the foam by heat and pressure, the temperature and residence time in the embossing device being chosen such that when leaving the device all plasticizer has disappeared from the foam. The foam is essentially derived by mixing an aqueous dispersion of a polymer with from 1-100% (based on the weight of the polymer) of at least one co-reactive material capable of cross-linking the polymer, foaming the mixture, gelling the foam and setting and drying the gelled foam. The polymer may be derived from at least two ethylenically unsaturated monomers chosen from styrene and monomers co-polymerizable therewith at least one of the monomers being styrene or a substitutedstyrene. Examples given are co-polymers of styrene, 1,3-butadiene and acrylic acid or styrene, 1,3-butadiene and fumaric acid or styrene, 1,3-butadiene, fumaric acid and acrylic acid. Alternatively the polymer may be a co-polymer of vinylidene chloride, vinyl chloride and 2 - sulphoethyl methacrylate. The polymer may include one or more of the reactive groups: carboxy, sulpho-, primary amino, secondary amino, carboxamido, methylolcarboxamido, sulphoamido, primary hydroxyl, secondary hydroxyl, phenolic hydroxyl aldehydic or epoxy groups. The co-reactive material may be melamine-formaldehyde resin, urea-formaldehyde resin, urea or melamine. The plasticizer may be water (applied as steam), xylene, trichloroethylene, perchloroethylene, carbon tetrachloride, ethyl alcohol, isopropyl alcohol or butyl alcohol. Embossing may be by a heated embossing roller and an unheated counter roller. The foam may be applied to the back of a carpet before embossing.

Patent ES-358277-A1 (ES)
Title: Method of manufacturing a pressurized fluid control valve
IPC: F16K11/07
Filed: 1968-09-18
Abstract: A reciprocating spool-type valve, particularly for controlling the supply and exhaust of pressure fluid to and from an actuator such as the jack 40, 42, comprises a valve body 22 having a chamber for the spool with longitudinally spaced inwardly projecting wall portions forming at least three annular valve seats such as the four seats 56, 60, 64, and 62, and a spool-like valve member having at least a pair of collars, such as the three collars 66, 68, 70, provided with corresponding closure surfaces for co-operation with the at least three seats, two of these closure surfaces 60, 64 being provided on one collar 68, such that one of these two closure surfaces along with a third closure surface such as 72 or 62, will seat simultaneously on the corresponding body seats. The valve may be controlled from the supply pressure of an air bottle 30 through a pilot valve 87 as shown. The valve may be pressure balanced by making the outer pair of closure surfaces of smaller diameter than the inner pair, Fig. 8 (not shown). In a double push-button valve, Fig. 4 (not shown), the inner pair of closure surfaces is made smaller so that the valve is held in each operated position by the fluid pressure. Similar effects can be achieved by recessing the inwardly projecting wall portions of the body, Fig. 13 (not shown). Methods of making.-Either the valve body or the spool, or both, may be moulded in a resiliently deformable plastics material such as polyurethane, neoprene, polyethylene, or rubber, and the spool is assembled by temporarily deforming one or other, or both, of the parts. Thus in Fig. 22, the plastic body 22 has been previously moulded in the material, using either a solid core which has been forcibly extracted or a destructible core otherwise removed. The spool is inserted, by bulging the body between plates 510, with an insertion tool 5081. The original body mould may be left on to form an outer casing (203), Fig. 6 (not shown). A spool 241, Fig. 23, pre-formed by the lost-wax process, has a lapping material 512 adhered to its closure surfaces by a substance 514 which can later be disintegrated and flushed away. Other details and variants.-A main spool and pilot spool valve arrangement may be formed in a one-piece body, Fig. 11 (not shown). The body can include an integral actuating lever with a roller (300, 302) or a solenoid (180) recessed into the body, Figs. 10 and 12 (not shown). Collar parts (105) only of the spool may be resilient, and grooves (157) may form flexible sealing lips carrying the closure faces, Figs. 8 and 18 (not shown). In a variant, the seats are flat and lands on the spool are grooved axially at (116). An adjustable flow restrictor in the exhaust passages is formed by a thin-walled portion of the body which is deformable by a ball (128) engaged by a screw (132), Figs. 15 and 16 (not shown).

Patent ES-378659-A1 (ES)
Title: Procedure for temporarily attaching a pressure plate to a heater plate
IPC: B29C43/20
Filed: 1970-04-16
Abstract: A pressure plate is temporarily attached to the heater plate of a laminating press by introducing between them a substance which is liquid or flowable under the press operational conditions and capable of exerting sufficient adhesion to maintain the pressure plate in position. If a cushioning pad is used between the heater plate and pressure plate, adhesive interlayers are used between the cushion and each of these plates. The attachment is achieved by assembling a lay-up of pressure plates, cushion pads (if used) and adhesive substances between the heater plates, with a protective board between the pressure plates, and actuating the press to adhere the pressure plates to the heater plates the press is then ready for use. The pressure plates are removed by pulling off, optionally after cooling. The adhesive substance may be introduced as one or more thermoplastic films (polycarbonate, polymethyl methacrylate polystyrene and polyethylene being used in examples), or may comprise silicone oil or, for use above 160 C., sulphur. Adhesion may be influenced by the use of softeners and separating agents or by roughening of surfaces. Heat conduction is improved by incorporating aluminium powder or graphite.
