  • Patent number: 11911834
    Abstract: A drilling tool for producing a bore with a cylindrical inner wall can be rotatable in a rotary movement with a predetermined rotational direction (VD) about a tool axis (A) extending through the drilling tool, and at the same time is movable in an axial forward movement (VB) in a forward direction axially to the tool axis. The drilling tool comprises at least one drilling area (3) arranged in a forwardly located region of the drilling tool at a forward or free end, but preferably not having a thread forming region. The drilling area has a number n of drilling edges which are arranged offset to each other in the rotational direction, and at least one chip divider is arranged on at least one or each of the n drill cutting edges, where the chip divider forms an interruption of the respective drill cutting edge.

  • Patent number: 4681211
    Abstract: Disclosed herein is a transport device for piece goods or the like, having rolling members (5) which directly support the piece goods. The rolling members (5) are arranged partly below a plate member which may be a unitary plate or segments (1) which supplement each other in plate-like manner. The rolling members (5) are supported on rolling drive devices and are guided in holes (3) in the plate member. The top portions of the rolling members (5) protrude above the top of the plate member and are arranged in linear rows (7) transverse to the direction of the transport. The transport device is a linear conveyor device which has simple drive devices, insensitive to heavy loads, on the rolling members (5) and, accordingly, can be driven over also by vehicles without the lowering of the rolling members (5). This result is achieved by providing the rolling drive devices in the form of cylindrical shafts (8) one of which is mounted centrally below each row (7) of rolling members (5) and parallel thereto.
