Title: Production of Expanded Mouldings of Olefin Polymers
IPC: B29B13/08
Filed: 1967-04-27
Abstract: Mouldings of expanded olefin polymers are formed by heating expanded particles of crosslinked crystalline homo- or co-polymers of olefins having two or three carbon atoms in a closed mould from which gases and liquid can excape but from which the expanded particles cannot escape. The particles are preferably compressed by 5-70 degrees volume per cent by moving two opposed mould sides towards the centre of the mould cavity. The polymer must have an X-ray crystallinity greater than 25% at 25 C. and may be polyethylene, polypropylene, a copolymer of ethylene and propylene or a copolymer of ethylene with various vinyl compounds especially acrylic esters. It may contain fillers, reinforcements, dyes, flame retardants, lubricants or other polymers and the degree of crosslinking may be increased by irradiation with X-rays or an electron beam. The expanded particles preferably have diameters of between 3 and 40 mm. Heating during the moulding process may be carried out by immersing the mould in a bath of liquid, by passing a heated gas through the mould or by introducing a heated gas into the mould cavity, the pipes being removed before compressing the particles.

Title: Heating apparatus for caravans and the like
IPC: F24H3/06
Filed: 1969-11-29
Abstract: A portable air heater, particularly for use in caravans &c., wherein the air to be heated is passed upwardly through a casing 1 by a fan 5 over the outside surface of a combustion chamber 11, 12 provided with a depending gas burner includes a thermoelectric generator 9 for supplying current to recharge a battery F used for lighting purposes. The thermoelectric generator, which forms the base of the combustion chamber, comprises series connected cells 9c disposed between an upper plate surface 9a heated by the burner and a lower plate surface 9b cooled by the air to be heated. Radial vanes 10, 17, 18 are provided to improve heat transfer. A rocking shutter 24 mounted on a spindle 23 is movable to direct the heated air from the casing either through openings 1c into the area to be heated or through openings 1d to the outside. The burner which comprises a Venturi tube 14 connected to a conical truncated chamber 15 closed by a perforated plate 16 is supplied with gas through pipe 20 and air through pipe 22. Combustion gases leave the chamber 12 through a discharge tube 13. A thermostat 7 controls valve 39 supplying gas to the burner. A safety circuit includes a thermo-couple 43 and a bimetal switch 10a both connected to a safety cut-off valve 38. The thermocouple senses the flame and the bi-metal switch acts to cut out fuel supply in the event of the fan 5 stopping causing the vanes 10 to over-heat. During start up only, additional fuel is supplied to the burner by way of a valve 42 to facilitate ignition. A cam (54, Fig. 4, not shown) operated by turning a knob 53, ensures simultaneously the opening of the safety cut-off valve 38, closing of the ignition circuit incorporating a filament 50, and supply of additional fuel. Provision of a by-pass pipe 40 having a calibrated opening 41 ensures a pilot operation of the burner when the valve 39 is closed. Circuitry including relays is provided to connect the generator to the battery F for charging purposes when required.

Patent ES-400620-A1 (ES)
Title: Seal assembly
IPC: F04B39/04
Filed: 1972-03-10
Abstract: The annular seal assembly and seal arrangements including the seal assembly disclosed are useful in high pressure pumps and compressors and the like that include a cylinder having annular grooves therein for receiving the seal arrangements and having a plunger reciprocating in the cylinder through the seal arrangements. The seal assembly includes segmented tangent and radial ring assemblies. Each of the segments in the tangent ring assembly includes tangentially disposed end surfaces that are arranged to sealingly and slidingly engage the adjacent tangentially disposed end surfaces. The radial ring assembly is constructed from a plurality of arcuate segments having an outer periphery sized to be closely fitted into a counterbore formed in one face of the tangent ring assembly. With the radial and tangential rings assembled, the forces exerted by the high pressure fluid on the tangent ring assembly are transferred to the radial ring assembly, providing better lubrication and longer seal life. The disclosed seal arrangements promote better operation and better seal life due to the distribution of the pressure load over several seals.

Patent ES-423055-A1 (ES)
Title: Method for cutting continuous yarns
IPC: D01G1/10
Filed: 1974-02-08
Abstract: A method for cutting continuous yarn includes compacting the yarn into a tubular piling in which the yarn is randomly curled. The piling is then sliced continuously as it is being formed to obtain a plurality of individual strands. The piling may be cut completely therethrough to form the strands or, on the other hand, may be cut only partially therethrough to form the strands. In either case, since the yarn has been curled randomly before being cut, the distribution of strand length obtained by cutting the piling will be variable.
Patent ES-425832-A1 (ES)
Title: Retractable towel cabinet
IPC: A47K10/28
Filed: 1974-04-30
Abstract: There is disclosed a toweling dispenser of the continuous type having a housing with a loop of toweling that extends along an exit path from a clean towel supply within the housing to an exposed use position accessible to the user, and thence along a return path through a soiled toweling accumulation chamber to a soiled toweling storage position within the housing, the dispenser having drive mechanism interconnecting a dispensing mechanism and a take-up mechanism that takes up soiled toweling from the loop and into the accumulation chamber after completion of the operation of the dispensing mechanism and a collecting mechanism that takes soiled toweling from the accumulation chamber into the storage position during operation of the dispensing mechanism, all under the control of a time-stop mechanism. The drive mechanism includes a preloaded constant torque spring motor which is wound during operation of the dispensing and collecting mechanisms and is unwound after timing out of the time stop mechanism to drive the take-up mechanism for taking up from the loop at least as much toweling as was dispensed during the dispensing portion of the cycle. The spring motor is designed to be wound more than it is unwound during each dispensing cycle so as to be completely wound after a predetermined number of cycles to provide sufficient power for completely retracting the training end of the exhausted soiled towel roll, a slip clutch preventing overwinding of the spring motor. Two embodiments are disclosed, in one of which the components are uniquely arranged to minimize the depth of the housing.
