Publication number: 20240003193Abstract: A cutting element may include a substrate; and an ultrahard layer on the substrate, the substrate and the ultrahard layer defining a non-planar working surface of the cutting element such that the ultrahard layer forms a cutting portion and the substrate is at least laterally adjacent to the ultrahard layer. Another cutting element includes a pointed region having a side surface extending from the pointed region outer perimeter to a peak. An ultrahard material body forms a portion of the pointed region including the peak, and a base region extends a depth from the pointed region outer perimeter. The ultrahard material body has a height to width aspect ratio with the height and width measured between two points of the body having the greatest distance apart along a dimension parallel with a longitudinal axis (i.e., height) along a dimension perpendicular to the longitudinal axis (i.e., width).Type: ApplicationFiled: September 19, 2023Publication date: January 4, 2024Inventors: Huimin Song, Xiaoge Gan, Zhijun Lin, Ke Chen

Publication number: 20220112773Abstract: A cutting element may include a substrate and an ultrahard layer. A top surface of the ultrahard layer includes a peripheral edge extending around the cutting element, a cutting crest extending across a major dimension of the cutting element from a cutting edge at a first portion of the peripheral edge to a modified region at a central axis of the ultrahard layer, and a lateral portion extending across a minor dimension of the cutting element from the peripheral edge to the modified region. The modified region along the major dimension includes a concave cross-sectional shape. The lateral portion along the minor dimension from the peripheral edge to the modified region includes one or more of a linear shape and a convex shape, and the modified region along the minor dimension includes a planar shape perpendicular to the central axis.Type: ApplicationFiled: December 23, 2021Publication date: April 14, 2022Inventors: Chen Chen, Huimin Song, Liang Zhao, Youhe Zhang, Michael G.

Publication number: 20210222488Abstract: A winding device for a non-stay-cord venetian blind is disclosed, which comprises a fixing seat, a fixer, winding drums with one-way dampers, a rear cover and iron cores. A non-stay-cord venetian blind adopting the winding device is also disclosed, which comprises a top beam, a bottom beam, slats, cords, a winding device, a motor and a shaft. The winding device adopts a unique separate settlement for the motor, which is convenient for mounting and displacement and easy to roll up and down. During the operation, the non-stay-cord venetian blind keeps horizontal and the bottom beam does not slide down or bounce back in any positions. The winding device is able to be applied on blinds adopt strip or string shaped ladder tape or blinds with center holes, side holes or side slots on the slats. Multiple cords are able to be winded the same winding drum.Type: ApplicationFiled: August 30, 2017Publication date: July 22, 2021Inventors: Zhijun Lin, Jianming Yu
