  • Patent number: 7624822
    Abstract: A thread joint for transmitting percussive forces includes a male thread on a male member and a female thread on a female member. The male member includes a first portion including an outer surface having a maximum first outer cross section, a second portion having a second maximum outer dimension, and a third portion having the male thread formed thereon. The second portion is disposed axially between the first and third portions. The male thread includes a thread start and a thread end. The third portion terminates in an axially facing first end surface. The female member has a recess in which the female thread is formed, the female thread having a mouth defined by a ring-shaped second end surface. The recess includes a cylindrical inner surface disposed between the second end surface and the female thread. The inner surface faces the cylindrical center portion of the male member.

  • Publication number: 20090264630
    Abstract: The present invention relates to a method of separating one or more monomeric proteins, such as monomeric antibodies, from a liquid. The method comprises providing a thiophilic aromatic chromatography matrix; contacting the liquid that comprises proteins with the matrix; and recovering at least one monomeric protein, such as a monomeric antibody, from the flow-through fraction. The proteins are advantageously monomeric antibodies.

  • Patent number: 6484823
    Abstract: A rock-crushing rotary drill bit includes a body having a rock-crushing roller rotatably mounted thereon by bearings. The body includes a first flushing channel for conducting flushing fluid to flush the bearings, and a second flushing channel for discharging flushing medium outside of the bit body to flush away cuttings. The second flushing channel terminates in a discharge recess which defines a linear center axis. A nozzle is disposed at a downstream end of the discharge recess, and a valve element is disposed at an upstream end of the discharge recess. The valve element is spring-biased for closing the discharge recess, the valve element being openable against the spring bias in response to a sufficient pressure build-up of flushing medium within the second flushing channel. The valve element includes a guide structure for guiding the valve element for linear movement along the center axis of the discharge recess.

  • Patent number: 6293360
    Abstract: A thread joint for percussive drilling equipment includes first and second percussive drill string components, the first component including a spigot. An external thread is formed on the spigot, and an internal thread is formed on the second component. Each of the internal and external threads includes an end section gradually transforming into a full thread section. The end section includes a pair of flanks, and the full thread section also includes a pair of flanks. Both flanks of the end section have a different profile than the corresponding flanks of the full thread section.

  • Patent number: 6021855
    Abstract: The present invention relates to a drilling tool for percussive drilling by means of a top hammer unit, which unit gives compressive pulses. The tool comprises at least one drill tube (12) and a drill bit (11), which cooperates via a connection. The drill bit comprises a bit head (13) provided with crushing means (15) and a shank (17). A shoulder (20) is provided in connection with the bit head, said bit portion having a first abutment surface (21) facing towards a free end of the tube. The free end of the tube facing towards the drill bit is povided with a second abutment surface (23), said top hammer unit being provided to tannsfer compressive pulses to the tube. Each compressive pulse is transferred to the drill bit via the impact surfaces (21, 23). The tube and the drill bit comprise cooperating device (19, 24, 25) for driving and retaining. The tool is defined by that it has a relation between the length of the shank and the length of the bit head that is 5 or more.
