Patent ES-461838-A1 (ES)
Title: Dispersion of antioxidant in cross-linkable polyethylene
IPC: H01B3/30
Filed: 1977-08-23
Abstract: This invention is an improved method for dispersing antioxidant material in cross-linkable insulation for electric cables. The antioxidant, which has a high melting point, is dissolved in a carrier, preferably the cross-linking agent, to obtain a solution of low melting point that is dispersed through the pellets of insulation when the ingredients are mixed in a blender. Improvements in the blender cycle reduce the content of fines, improve dispersion of the antioxidant and shorten the blending cycle. The preferred ingredients used are 4,4'-thiobis (6 tert-butyl-m-cresol) as the antioxidant and dicumyl peroxide as the cross-linking agent.
Patent ES-463034-A1 (ES)
Title: Method of producing a thermally and acoustically insulated pipe
IPC: B29C48/151
Filed: 1977-10-07
Abstract: Using an extruder die (1), in the process an outer pipe (2) made of thermoplastic is extruded coaxially to an inner pipe (6) fed continuously over a guide pipe (5). Then, using a mixing device (9), a reactive foam composition (11) forming the heat-insulating layer is introduced by means of a mixing device (9) into the annular space between the inner pipe (6) and the outer pipe (2). This foam composition (11) is sprayed onto a conveyor belt (7) running off from a supply reel (8). The foam composition (11) is formulated such that it does not fill the annular space until the outer sheath (2) has sufficient strength. The extruded outer pipe (2) is calibrated in a subatmospheric pressure chamber (3) partly filled with water and intensively cooled in a second chamber (4). The film used hitherto for forming a mould cavity for the insulating layer and the forming device for this film are dispensed with.

Patent ES-476089-A1 (ES)
Title: Fan cylinder having invisible eased inlet
IPC: F28C1/00
Filed: 1978-12-18
Abstract: Air moving mechanism is provided for equipment such as direct or indirect heat exchange cooling towers. Conventional cross-sectionally elliptical eased inlet structure leading to a fan opening or cylinder surrounding a rotary fan air mover is replaced by a much simpler, less costly, apertured airflow modifying baffle member which functions to define an invisible eased inlet for the fan. The specially shaped aperture in the baffle member is configured and arranged relative to the fan cylinder inlet to cause air removed from the tower casing and directed toward the fan to follow a transition path between the baffle member and fan opening or cylinder which generally conforms to and substantially fills the opening or cylinder inlet around the entire circumference thereof. In those instances where air enters the tower casing on one side, or on opposed sides of the fan structure only, the orifice in the baffle is formed of somewhat rectangular shape with edge portions thereof aligned with the air inlet sections of the tower in greater spaced relationship from the axis of the fan opening or cylinder than the remaining edge portions of the aperture to compensate for the more radial airflow patterns toward the cylinder or opening from the parts of the tower which receive ambient air as contrasted with the axially oriented airflow toward the fan cylinder or opening from the closed parts of the tower casing.

Patent ES-8305885-A1 (ES)
Title: Fuel injection pumping apparatus
IPC: F02D1/08
Filed: 1982-05-28
Abstract: A fuel injection pumping apparatus of the rotary distributor type has a distributor member which is also axially movable to determine the allowed outward movement of the pumping plungers and hence the amount of fuel supplied to the associated engine. The extent of outward movement is determined by inclined stop surfaces which co-operate with complementary surfaces on shoes associated with the plungers. In order to minimize axial movement of the distributor member when the shoes engage the stop surfaces a chamber to which liquid is supplied to vary the axial setting of the distributor member, is locked off from fluid supply and drain passages, by a servo valve 41 when the correct position of the distributor member is obtained. A hydraulic lock is thus created in the chamber.
