Patent ES-337872-A1 (ES)
Title: Apparatus for compressing and packing molding sand
IPC: B22C15/12
Filed: 1967-03-10
Abstract: Sand in a succession of mould boxes 3 is compacted by dropping a battery of rows of rammers 10 movably guided by cylindrical portions 9 in sleeves of a frame 5 suspended from a beam 12 lifted by a compressed air cylinder 15 and piston 16 to raise the rammers. Buffers 34 determine the bottom position of the frame and beam. The rammers 10 and their heads 8 may be of square or hexagonal section. The air cylinder 15 is fixed to a frame member 14 and air from its inlet groove 21 passes into the piston 16 (containing a space-resitrictor 18) through a piston groove 20 until this is cut off by the rising of the piston. A further cylinder groove 22 releases the air when cleared by the piston skirt to allow the piston 16, beam 12, frame 5 and rammers 10 to drop. The mould boxes 3 are advanced step-by-step by a conveyer 2, being filled by a hopper behind the machine and bevelled by a scraper (27) at the front.

The shells 3, 4 and ejector plates 13, 14 are coaxially pivoted to a cross-head 2 at 5, 5a.
Patent ES-355855-A1 (ES)
Title: Float glass apparatus with longitudinal dams and metal flow control means
IPC: C03B18/18
Filed: 1968-07-06
Abstract: In float glass apparatus the float tank contains a pair of dams 10, 101 disposed in spaced relationship to define a path for the glass ribbon to be formed, the dams being spaced from and extending parallel to the side-walls over at least part of the length of the tank and extending above the bath level, and means to control the flow of molten metal between each dam and the adjacent side-wall. In the preferred embodiment the dams 10, 101 extend upwardly from the tank bottom. They are made of a gas permeable material 13, preferably graphite, and have on the inside of such material a longitudinal cavity 14 into which a non-oxidizing gas is fed. Gas permeating the material 13 prevents contact between the dam 10, 101 and the glass ribbon. The dam is also water cooled. The flow of molten metal 31, 311 between the dams and the sidewalls 22, 221 is controlled by water-cooled graphite dampers 21, 211 which can be located in the molten metal bath to desired depths. The combination of dampers and dams reduces the flow of molten metal beneath and parallel to the moving ribbon and reduces contamination of the undersurface of the ribbon. In an alternative embodiment a rotatable water cooled graphite roller is located in the channel defined between the dam 10 or 101 and side-wall 22, 221. Other alternatives mentioned are pairs of adjustable dampers wholly immersed in the molten metal 31, 311 or the use of induction motors to set up a forced flow of molten metal. If there is no contact with the glass ribbon spheroidal graphite cast iron may be used in place of graphite. Reference has been directed by the Comptroller to Specification 1,103,276.

Title: Improvements in and relating to Disc Brakes.
IPC: F16D65/12
Filed: 1968-10-25
Abstract: Means for fixing brake rings of disc brakes to each side of a vehicle wheel comprises a tubular member or sleeve passing through each of a plurality of holes spaced circumferentially around the wheel disc and extending at each of its ends into a blind bore or recess formed in the respective brake ring the tubular member or sleeve is fixed in the blind bore or recess of each brake ring by locking bolts or pins passing radially into, or diametrically through parts of, the brake ring and engaging in notches or recesses in the tubular member or sleeve. Each brake ring 13 or 14 has a number of circumferentially-spaced boss portions directed, in use, towards the rail vehicle wheel 11, 12, Fig. 1, with which the brake rings are associated. Each boss portion has a blind bore 15. Before fitting the brake rings, a sleeve 19 is inserted in each one of a number of holes 16 provided in the disc portion 11 of the wheel. Then the brake rings are slid inwards so that the blind bores 15 engage the sleeves 19. Each boss portion is provided with a recess 28 forming a shoulder which engages a corresponding shoulder on the wheel disc portion 11. These arrangements permit outward radial expansion of the brake rings. Each brake ring is fixed to each of the sleeves 19 by locking bolts 17 passing radially into the brake ring, each bolt having a frustoconical end portion 18 engaging a notch 20 in the sleeve 19. Modification.-In Figs. 2 and 3 each boss portion (shown in cross-section in Fig. 3) in each brake ring is previously fitted with a locking pin 25 having a reduced middle portion. The brake rings are then pushed inwards until each such middle portion engages the rounded ends of two diametrically-opposite keyhole slots 21, 23, provided in the adjacent end of sleeve 26. Slots 24 increase resilience at the sleeve ends.

Abstract: Microporous sheets are produced by forming an emulsion composition comprising fine droplets of a liquid dispersed in a continuous phase which comprises reactive material comprising a mixture of a component providing a plurality of -NCO groups and a component providing active hydrogen convertible through reaction to form solidified, resilient polyurethane, the liquid being substantially non-solvent for the reactive material and immiscible in the continuous phase and being present in amount from 25 to 300% by weight based on the weight of the reactive material, causing the reactive material to react at a temperature below the boiling point of the liquid whereby the emulsion gels and solidifies to form a mass, slicing the mass into sheets of a desired thickness after the mass has sufficiently solidified and while the droplets are retained in the material, and, after the material has solidified sufficiently not to collapse upon removal of the droplets of liquid, removing the liquid to leave pores and discontinuities in the solidified material. The polyisocyanate may be in the form of a prepolymer. Suitably the liquid is a liquid aliphatic hydrocarbon including petroleum hydrocarbon fractions and particularly those commercially available as mineral spirits, petroleum naphtha and kerosene, and preferably has a boiling point of at least 100 C. Dispersion of the poreforming liquid is effected by vigorous agitation, optionally in the presence of an emulsifying agent. The slicing operation may be carried out using a band knife splitter and preferably after slicing the sheets are heated to complete the cure and remove by evaporation the liquid of the entrapped droplets as the cure is completed.

Patent ES-444368-A1 (ES)
Title: Indicating entry into a variable width right margin zone
IPC: G06K15/06
Filed: 1976-01-16
Abstract: A system which utilizes a floating hot zone for controlling quality of ultimately justified output text. In preparing text for later justified output, the minimum space size is set at three units. The zone is variable in width and located within the measure and adjacent the right margin. The width of the zone is partially dependent upon the number of spaces on a line. During printing, the left side of the zone is tentatively established when the residue is equal to, or less than, 36 units. Then, when the residue is equal to, or less than, the number of spaces times nine, the system will cause a bell to ring. This will alert the operator that the zone has been entered and if printing is thereafter terminated, the maximum space size will not exceed 12 units during later justified output.
