Title: Improvements in or relating to the purification of hydrocarbon oils
IPC: C10G49/00
Filed: 1963-08-20
Abstract: Light distillates are purified down to a level of not more than 0.3 p.p.m.of sulphur, by removal of sulphur therefrom, by passing a mixture of the light distillate in vapour form and a hydrogenating gas containing oxides of carbon, the mixture containing at least 3 parts by volume of hydrocarbon per volume of hydrogen but containing a substantial excess of hydrogen over that required for reaction with unsaturated hydrocarbons, carbon monoxide and carbon dioxide in the mixture, over a hydrosulphurization catalyst comprising molybdenum supported on alumina and promoted by nickel, thereby converting sulphur present to hydrogen sulphide, which is subsequently removed from the distillate, for example by contacting with iron oxide. The process is preferably effected at 250-450 DEG C. and 5-50 atmos., the distillate being passed through the catalyst at 50-600 v./v./hr.
Patent ES-296568-A1 (ES)
Title: Improvements in and relating to the casting of metal
IPC: B22D35/04
Filed: 1964-02-18
Abstract: In a method of bottom pouring the metal flows through a horizontal runner which reduces the turbulence of the flow and allows inclusions to rise to the surface to form a layer, and only the metal below said layer is allowed to flow into the mould. The runners 12 are of varying cross-section to reduce turbulence and a barrier 17 holds back the inclusion layer. In a modification, Fig. 3 (not shown), the runner 12 leads from the trumpet to a distributer block 19 from which conventional runners 18 lead to the moulds.

Title: Apparatus for attaching container covers by adhesive means
IPC: B31B50/62
Filed: 1967-04-06
Abstract: Apparatus for securing a lid to a container body by a hinge flap on the body or lid comprises a conveyer for passing the body, with the lid in position, to an adhesive applicator, means to cause the applicator to apply a strip of adhesive between the flap and body or lid and means to fold down the flap. The body 31 is prefilled with e.g. cigarettes and the lid applied, the so formed units being fed from a shoot 30 in front of dogs 20 (see also Fig. 3) on the conveyer 10. A rail 17 folds back the flap 33 and an applicator 41 as described in Specification 1,176,734, is caused by a cam 50 and control means 60, 63-67, to eject a strip of hot melt adhesive on to the body. A continuation of the rail 17 then folds down the flap and holds it for sufficient time to set the adhesive. It may be cooled to assist setting. Photoelectric means (not detailed) may be used to detect absence of a unit. The body and lid may be of drawn plastics.

Title: Process for lowering the hydroxyl group content of an epoxy resin by transesterification
IPC: C08G59/42
Filed: 1967-04-20
Abstract: Epoxy resins have their hydroxyl content reduced by reaction with an ester <FORM:1115578/C3/1> in which R1 is hydrogen or an alkyl, aryl, alkenyl or aralkyl radical R2 is a C1- 6 alkyl or alkenyl radical and R is a chlorine atom or a radical -COOR3 where R3 is a C1- 6 alkyl or alkenyl radical, or a radical -COR4 where R4 is an alkyl, alkenyl, aryl or aralkyl radical. Examples of suitable esters are ethyl acetoacetate and ethyl chloroacetate. Reaction may take place in the presence of a large excess of the ester the remainder of which is distilled from the treated epoxy resin at the end of the reaction. A basic catalyst, e.g. an alkoxide of an alkali or alkaline earth metal may be employed. Conventional hardness may be used to cure the modified resin.
Patent ES-343486-A1 (ES)
Title: Apparatus for filling molds
IPC: B27N5/00
Filed: 1967-07-27
Abstract: The nonflowing molding materials are blown into the mold cavity which has a screen defining one surface of the article to be molded. The materials first fill up the remote areas of the cavity as the carrying air vents through the screen. As the cavity fills up to the feeding nozzle, a vent flap in the nozzle body opens up, allowing the carrying air to vent through the screened opening exposed by the flap until the mold is completely filled and the air is cut off.

Patent ES-346016-A1 (ES)
Title: Apparatus for processing of strip metal in a continuous manner to remove undesired curvature
IPC: C21D9/18
Filed: 1967-10-13
Abstract: Continuously moving steel strip 10 e.g. for making into razor blades is hardened by heating the strip e.g. to 2000 F. (1093 C.) to produce austenite and cooling the strip rapidly to convert the austenite to martensite whilst subjecting it to a differential stress to reduce transverse curvature and flatten the strip, preferably by bending the strip over a sharp edge 150 as shown e.g. while it is at a temperature of 320 F. (160 C.) at the exit of an air cooled transition zone prior to passing through a quench unit and into a freeze unit e.g. at -90 F. The strip may be finally tempered e.g. at 500 F. The quench unit may include a water cooled lower quench plate held by clamps 62 and an air cooled upper quench plate 64 between which the strip passes. The height of the quench unit may be adjusted relative to that of a strip supporting U-shaped insert 140 in a tube 136 of the air cooled zone to effect the desired stress in response to the detection of excess transverse curvature in an inspection station following the tempering furnace. A steel composition specified is: 0À37-0À44%C, 13-14%Cr, 0À2-0À5% each of Mn and Si, 1À15-1À35% Mo, balance Fe and impurities.

Patent ES-359794-A1 (ES)
Title: Apparatus for Trimming and Splicing Wires
IPC: H01R43/04
Filed: 1968-10-31
Abstract: Apparatus for trimming and splicing wires comprises a die 3 movable towards a die 4 to crimp a U-section connector 87 to a pair of wires (X, Y), Fig. 2 (not shown), a pair of wire trimming edges 39, 41 extending lengthwise of the path of movement of the die 3, and a pair of associated rotatable blades 32, 36 for trimming the wires between the ends of the connector. As shown, the lower, stationary die 4 has curling surfaces 5 for closing the limbs of the connector, and the upper die 3 is flat and operated through a one-revolution-clutch, by an A.C. induction motor. Feeding.-A strip of connectors, joined by bridges of insulation, is advanced in steps by a pivoted lever 18 having a peg 24 which projects through a slot 51 in a feed channel to engage holes in the bridges. A spring-pressed plate (not shown) pressing the connectors upwardly into the channel is deflected downwardly as the die 3 engages the end connector, thus freeing the strip of connectors from the peg 24 and allowing the feed arm 18 to make a return stroke through contact between a cam 14 on the die 3 and a follower 16 on the arm 18. When the die 3 has returned after crimping, the cam 14 permits a feed stroke of the arm by the arm's return spring 22. An end 48 of the feed channel engages behind (Fig. 2) a stop-plate 44 for the connectors and forms a passage 50 for the die 3. Shearing.-The ends (XE, YE) of wires in passages 60, 61 in rubber &c. guides 52, 54 extend beneath the effective zone of the adjacent shear blades, upwardly to be trimmed by the opposite blades as these are turned about a pivot 34 by pins 21 projecting beneath the die 3. A stationary plate 26 has a projection 30 against which the insulation bridges are sheared by the die 3 as this lowers a connector towards the die 4. In various modifications, the die 3 may include a connector guide which is retractable into the die against spring-pressure. The guide may bias the connector towards the shearing block 40, the press may be disposed horizontally or at an angle to the horizontal and the die 4 may be uppermost. The guide blocks 52, 54 may be of rigid material and movable away from the die 3, and the press may be operated by fluid-pressure or through a linkage, by one or more rotatable handles. The wire-trimming blades may be turned about different axes, preferably for use with offset trimming edges, so that the wires are not crossed. A flat lower die may be used to which the connectors are fed, the shear plate 26 being fixed to the movable die, and the feed mechanism replaced by one for engaging upstanding tongues 66 on the connectors. The apparatus may be a hand tool or mounted on a rack or bench.

Patent ES-415914-A1 (ES)
Title: Method of fabricating an apertured mask for a cathode-ray tube
IPC: H01J29/07
Filed: 1973-06-14
Abstract: A metal sheet is embossed by a special embossing tool to provide regions in the sheet of minimum thickness at the intended aperture locations thereon. Following embossing, the sheet is shaped into a desired mask contour and the embossed side of the sheet is coated with a stop-off substance to prevent subsequent removal of material from that side. The regions of minimum thickness are then removed, such as by etching the uncoated side of the sheet, to provide the apertures.
