The cross section in the connection zone is void-free and seam free. | 2022-07-28 |
20220234151 | METHOD FOR FORMING CUTTERS - The method for forming cutters includes applying a protective layer on an O-ring so as to form a protected O-ring. The protected O-ring is placed around a cutter body having a substrate section and diamond section with a metallic binder. The method includes inserting the cutter body into the pod cavity and leaching the metallic binder through an end portion of the diamond section for at least one day at 60 degrees Celsius or higher so as to form a polycrystalline diamond compact cutter from the cutter body. The protected O-ring seals the substrate section during the step of leaching. The step of leaching forms an exposed O-ring from the protected O-ring with a hardness reduction and a modulus reduction that identifies a time window for maintaining a sealing force to protect the substrate, while achieving the target profile of the diamond table for a high quality and reliable cutter. | 2022-07-28 |
20220234152 | DEVICE FOR DISTRIBUTING CLIP-TYPE COMPONENTS - A device for distributing clip-type components for assembling parts includes a main magazine for bulk storage of the components, a tray for temporary storage of components extracted from the main magazine, configured to temporarily store the components to be transferred out of the device and mounted for reciprocating translation in a longitudinal direction to shake the temporarily stored components and facilitate their positioning inside the tray in a predetermined stable position corresponding to their shape. The device includes an optical detection system to detect, from among the components temporarily stored inside the temporary storage tray, the components having the predetermined stable position, and a transfer system to transfer the components having the predetermined stable position to a downstream processing area outside the device. The device further includes an electronic control unit connected to the optical detection system and the transfer system, the unit configured to control the transfer system. | 2022-07-28 |
20220234153 | APPARATUS AND METHOD FOR POSITIONING A SAFETY STRAP - An apparatus for positioning a strap around an object includes a handle for being grasped by a user of the apparatus. The apparatus further includes an arm portion having a first end coupled to the handle portion and an opposite second end having a coupling mechanism coupled at or nearby for selectively coupling a portion of the strap to the second end of the arm portion. When the handle portion is grasped by the user of the apparatus adjacent a side of the object the arm portion is sized and configured to be movable among: a first positioning wherein the arm portion extends outward from the handle and the user such that the second end of the arm portion extends a distance beyond a far side of the object, and a second positioning wherein the arm portion wraps at least partially around the object. | 2022-07-28 |
