Patent ES-342886-A1 (ES)
Title: Method of sharpening twist drills
IPC: B24B3/24
Filed: 1967-07-11
Abstract: A method of sharpening a twist drill having on each of its symmetrical surface portions a conical surface 8 which is tangent to a partspherical or part-toroidal surface 9, comprises sharpening the conical portion 8 against the plane of a grinding wheel 4 by rotating the drill about an axis # other than its longitudinal axis XY, and sharpening the portion 9 by adding to the preceding movement of rotation, a first relative rotation between the grinding wheel and the drill about an axis MP containing a centre of the part-spherical or toroidal surface as well as, in the case of a part-spherical surface, a second simultaneous rotation of the drill about its longitudinal axis. In apparatus for carrying out the method, an arm 11 is mounted for rotation by a handwheel 20 about an axis # in a frame 12 and at its end carries a bracket 13a for rotation about an axis MP by a handwheel 19. The bracket supports a drill holder 13 which is rotatable about the axis XY of a drill held in a chuck 13 by a toothed gear in a casing 15 engaging a rack 16 movable by a follower 17 engaging a cam 18 as the drill holder is rotated about the axis MP. The grinding wheel 4 is mounted in a block 22 vertically adjustable on a bracket in turn adjustable horizontally in two perpendicular directions on a support 24 pivoted about an axis TV on a sector 26. The sector is adjustable in two perpendicular directions on a base plate 28 pivotable about an axis SV in alignment with the axis MP. In operation, the conical surfaces 8 are ground by movement of the arm 11 so that the drill is rocked about the axis #. If the surface 9 is to the part-spherical, the axis TV is adjusted to be in alignment with the axis MP and as the drill holder is rotated about the axis MP the drill is simultaneously rotated about its axis XY. If the surface 9 is to be part-toroidal, the axis TV is displaced from axis MP and the grinding wheel is moved about axis PV as the drill is rotated about the axis #. The perpendicular distance between the axis # and the axis XY of the drill is adjustable by vertical movement of the holder 13 on its support 13a.

Title: Apparatus for continuously producing raised marks on plastic cable jackets
IPC: H01B7/36
Filed: 1976-03-01
Abstract: The apparatus for producing raised markings on a cable's plastic jacket disclosed provides for at least one drum shaped marking member, which may be driven by the cable itself or, if there are a pair of such drums, at least one is driven by means of a stepper motor which is controlled synchronously with the cable take-off speed. The drums are vertically adjustable and mounted on swivel arms carried on a carriage. Pneumatic means are employed to force the drum or drums against the moving cable with a predetermined pressure. Depressions corresponding to the desired markings are formed in the circumferential surface of the drum. As the drum or drums rotate a powder filled container or filling head is pressed against them so that powder is picked up in the depressions and carried by the drums into contact with the cable. When the powder filled depression area of the drum contacts the cable, which is still hot, the powder will fuse with the material of the cable's jacket and form a raised marking. The depressions may be symbols, letters, numerical length marks and the like.

Title: Apparatus for packaging nested, uniformly shaped articles
IPC: B65B5/06
Filed: 1977-05-04
Abstract: Apparatus for inserting a charge of nested, uniformly-shaped articles into a container such as a cannister. A charge of the articles, which may be uniformly-shaped articles and may be fragile articles such as farinaceous food chips, is separated by a metering unit from a supply of such articles and transferred into a hollow sleeve member. The filled sleeve member is rotated to a container-receiving position in which a container, such as a cardboard or paperboard cannister having one open end, is positioned over the filled sleeve member. The filled sleeve and container are then rotated to a release position in which the container, with the charge of nested, uniformly-shaped articles therein, is released from the sleeve member onto a receiver such as a conveyor which moves the filled container for further processing, for example purging with an inert gas and closing the open end. The metering unit may be, by way of example, a conveyor having a pair of gates which operate to separate a charge of the desired size from the supply of nested, uniformly-shaped articles. The metering unit can include a discharge portion pivotally attached to the conveyor main portion and contacting the sleeve member to assure against any of the articles failing to enter the sleeve member, with the discharge portion pivoting from the path of travel of the sleeve member as the sleeve member is rotated from the filling position. A plurality of hollow sleeve members can extend from a rotatable hub to move between angularly spaced filling, container-receiving, and container-discharge positions.

Title: Shore erosion control structure
IPC: E02B3/06
Filed: 1978-06-16
Abstract: A seawall structure adapted to combat erosion of a shoreline by wave action comprises a perforate wall arranged along and substantially parallel to the shoreline and having openings therethrough facing seaward through which the water of incoming waves may pass.
