Patent number: 8696269Abstract: A support pad intended for metal machining drills and of the type that includes an outer surface, an inner surface, front and rear end surfaces, as well as a pair of spaced-apart side surfaces, between the outer surface and at least the front end surface a convexly arched entering surface being formed that extends between, on one hand, a pair of front and rear borderlines, the rear one of which borders the outer surface, and, on the other hand, two tangentially spaced-apart side borderlines. The rear borderline of the entering surface has the shape of a convex arc line as viewed in planar view toward the outer surface, more precisely an arc line the crest of which is facing forward. In such a way, the position of the contact of the support pad with a hole wall can be predetermined in an exact way. The drill body may be equipped with one or more support pads.Type: GrantFiled: December 17, 2009Date of Patent: April 15, 2014Assignee: Sandvik Intellectual Property ABInventor: Åke Danielsson

Patent number: 8449227Abstract: A rotatable tool for chip removing machining including a basic body and a loose top; the body includes two torque-transferring drivers and an intermediate bottom in which a rear coupling part of the loose top is receivable, and a center hole that mouths in the intermediate bottom. A centric pin is insertable into the center hole, and a screw is accessible from the outside of the basic body. The coupling part includes a pair of side contact surfaces which cooperate with a pair of side support surfaces on the drivers of the basic body for the transfer of torque and negative axial forces between the coupling part and the drivers.Type: GrantFiled: June 8, 2010Date of Patent: May 28, 2013Assignee: Sandvik Intellectual Property ABInventor: Åke Danielsson

Patent number: 7972508Abstract: A rotary disc filter device includes a rotary drum and one or more disc-shaped filter members secured about the drum. Each disc-shaped filter member includes a filter disposed on opposite sides thereof and each disc-shaped filter member includes a modular frame made up, in part at least, by a series of interconnected modules. One module of the modular filter frame includes a base that is secured to the rotary drum and a support projecting outwardly from the base. A series of these modules are interconnected to form a modular filter frame.Type: GrantFiled: September 30, 2009Date of Patent: July 5, 2011Assignee: Veolia Water Solutions & Technologies SupportInventors: Åke Danielsson, Åke Ralvert, Emil Svensson, Per Larsson

Patent number: 7597805Abstract: A rotary disk filter and a module for building a filter support for a rotary disk filter are disclosed. The rotary disk filter may comprise a drum, which is rotatable about its central longitudinal axis. The rotary disk filter may be adapted to receive a liquid which is to be filtered. In one implementation, the rotary disk filter may comprise at least one disk-shaped filter member which on the outside of the drum extends outwards in the transverse direction of the drum, and which has a filter support and at least one filter portion supported thereby. A first liquid duct may extend from the drum through the filter member and out through the filter portion. The filter portion may be made of filter segments, which are detachably secured to the filter support. At least one second liquid duct may extend between adjoining filter segments to provide liquid communication between the filter segments.Type: GrantFiled: February 24, 2004Date of Patent: October 6, 2009Assignee: Hydrotech Veolia Water Systems AktiebolagInventors: Åke Danielsson, Åke Ralvert, Emil Svensson, Per Larsson

Patent number: 7320565Abstract: In a first aspect, the invention relates to an edge-carrying drill body (1) of the type that is intended for deep hole drilling, and which is rotatable around a geometric axis (C) as well as comprises a through channel (2) arranged for internal chip evacuation, which channel mouths in front and rear ends of the body. Characteristic of the invention is that one or more cutting edges (4) are made integrally with the rest of the body, more precisely from a hard material, such as cemented carbide or CERMET. In a second aspect, the invention also relates to a method for the manufacture of such a drill body. In a third aspect, the invention furthermore relates to a drilling tool for deep hole drilling.Type: GrantFiled: May 20, 2004Date of Patent: January 22, 2008Assignee: Sandvik Intellectual Property ABInventors: Åke Danielsson, Bengt Silver

Patent number: 6682275Abstract: A deep hole drill for chip-removing drilling in a workpiece includes a body which has a cutting head and an integral cutting part. The body defines a longitudinal axis of rotation and has a longitudinal internal channel which opens into an end face of the cutting head for receiving cuttings that are entrained in a cooling medium. A chip removing insert is disposed on the cutting head. A support pad and a guide bar are disposed on a generally cylindrical outer peripheral surface of the cutting head and are arranged in circumferentially spaced relationship to one another. Cooling ducts are formed in the outer peripheral surface and are oriented generally parallel to the axis. The cooling ducts are open at the end face for conducting cooling medium thereto. The cooling ducts are situated adjacent the support pad and guide bar, respectively, for cooling same.Type: GrantFiled: March 5, 2002Date of Patent: January 27, 2004Assignee: Sandvik AktiebolagInventors: Stefan Lindblom, Åke Danielsson

Patent number: 6596166Abstract: Apparatus for cleaning a filter cloth in a filtering device with a rotatable drum having an inlet for the liquid to be filtered. The drum has in its circumferential surface openings through which the liquid to be filtered is conducted in a filtering direction out of the drum for filtering through a filter cloth. The cleaning apparatus includes at least one spray nozzle which is adapted to spray cleaning liquid onto a portion of the filter cloth in a direction opposite to the filtering direction. Moreover the apparatus comprises a driving device for providing a reciprocating motion of the spray nozzle. The driving device has a coupling which is adapted to transform the rotary motion of the drum into the reciprocating motion of the spray nozzle, with such a ratio that the rotary motion of the drum and the reciprocating motion of the spray nozzle are out of phase with each other.Type: GrantFiled: September 24, 2001Date of Patent: July 22, 2003Assignee: Hydrotech Nils-Ake Persson ABInventors: Åke Danielsson, Åke Ralvert
