Patent ES-353983-A1 (ES)
Title: Process for manufacture of porous sheet material and a porous sheet having a textile substrate
IPC: D04H1/645
Filed: 1968-05-17
Abstract: A process for the manufacture of porous sheet material comprises applying to a substrate a liquid, homogeneous mixture of a polymer and an auxiliary substance which consists essentially of a solvent for the polymer, but which on cooling of the mixture precipitates therefrom, to a substrate, cooling the mixture to form a solid phase and then removing the auxiliary substance. A single substance for a mixture of substances may be used as an auxiliary substance. Suitable materials are lactams such as pyrrolidone, caprolactam and N- substituted lactams. Other similar materials are also specified. The auxiliary substance may conveniently be removed with water. The polymer material may be polyurethanes either alone or mixed with other polymers such as polyvinyl chloride or polyvinyl alcohol. Copolymers of ethylene and vinyl acetate and of ethylene and propylene may also be used and also other rubber like materials such as poly-2, 6-dimethylphenyleneoxide. The substrate may be fibre sheets and filament sheets or mats of polyamides, polyesters, polypropylene, polyvinyl alcohol, acrylic polymers, regenerated cellulose, wool, cotton, glass or mixtures of these.
Patent ES-357582-A1 (ES)
Title: Method for cooling the mold blocks of a casting machine with caterpillar mold
IPC: C21D1/00
Filed: 1968-08-26
Abstract: A continuous casting machine of the type in which a co-operating pair of endless sets of articulated mould blocks are driven at the same speed so that over a portion of their run they are in engagement one with the other and define between them a moving mould cavity, has a casing 10 positioned away from the casting and opening towards the mould blocks 11, the casing 10 containing a number of spraying nozzles which are arranged to direct a spray of cooling liquid against the mould blocks 11, and means for providing a reduced pressure within the casing. The mould blocks are cooled during their upward idle run, the casing 10 containing a number of horizontal spraying pipes 13, each having a number of spraying nozzles, each pipe being caused by a deflector 15 to deflect water pouring down the faces of the mould blocks. Air is sucked out of the casing 10 through a pipe 18 and the resulting inrush of air through the space between the mould blocks and the edge of the casing prevents loss of coolant through this space. Water is removed from the casing 10 through a pipe 17. For cooling the mould blocks of horizontal casting machines, the casing 10 is divided into upper and lower chambers, Fig. 5 (not shown), the lower chamber containing the spraying nozzles and the upper chamber the coolant discharge pipe, the two chambers being connected by tubes sealed to and extending through the partition.

Title: Cross-linking process
IPC: B29C48/08
Filed: 1969-05-14
Abstract: Shaped articles of cross-linked polymeric material are prepared by subjecting a shaped article of a crystalline polymer containing a thermally activatable cross-linking agent to a pressure sufficient to cause a rise of at least 10 C. in the crystalline melting point of the polymer, and heating the article while under pressure to a temperature below the crystalline melting point of the polymer at the applied pressure and at which cross-linking will occur. Specified polymers are polyethylene, polypropylene, polyamides and polyesters, e.g. nylon 66 and polyethylene terephthalate. Preferred cross-linking agents for polyolefins are peroxides, optionally with non-conjugated polyenes, e.g. polyunsaturated esters and poly-[alpha]- alkenyl aromatic hydrocarbons. The article may be a sheet, film, fibre, pipe or pipe fitting, and the pressure may be applied via a liquid or gaseous medium, particularly water. Some cross-linking may be effected at temperatures above the crystalline melting point. Examples describe the cross-linking of polyethylene in the presence of (1 and 2) dicumyl peroxide and (3,4 and 8 to 11) di-t. butyl peroxide and of polypropylene with (7) 1,1,4,4,7,7-hexamethyl cyclo-4,7-diperoxynonane.

Title: Vending machine
IPC: G07F13/06
Filed: 1972-05-04
Abstract: A drink vending machine has a cabinet in which two liquor containers are supported. A rubber hose connects each container to an optic type measure and to the bottom of a sight glass which extends upwardly from the optic type measure. Two platforms are mounted on a common lever below the measures respectively, and the lever is tipped by the weight of a drinking glass placed on one of the platforms, thereby closing a circuit which causes a drink to be discharged from the selected measure if coins are simultaneously deposited in a coin-feeding apparatus. A float in each sight glass may cause the coin slot to be blocked and an "empty" sign to light up when the float interrups the passage of light between a light source and a photoelectric cell.

Title: Apparatus for dispensing cap lining material
IPC: B29C65/00
Filed: 1977-02-15
Abstract: An apparatus for dispensing predetermined amounts of lining material into cap shells, particularly of the deeply recessed type, includes a conveyor including a passage for conveying cap shells at predetermined speeds, an extruder provided above and along the shell-conveying passage for extruding predetermined quantities of a lining material through a discharge passage, a blade fitted adjacent to the exit end of the discharge passage and rotatably across it for cutting the lining material, and a drive for rotating the blade in response to the conveying of the cap shells. The drive is adapted to rotate the blade at a non-uniform speed in response to the speed of shell conveyance so that its speed gradually decreases as the exterior end of the blade in its radial direction approaches the shell-conveying passage, and gradually increases as it departs from it, whereby collision between the tip of the blade and the cap shells can be completely avoided.
