  • Patent number: 10422922
    Abstract: A system and method to predict rock strength by directly inverting for petrophysical properties. In one embodiment, seismic data is received or obtained from a seismic survey (step 101). The seismic data are then conditioned (step 103) in order to prepare them for an inversion process (step 105). The inversion process has an embedded rock physics model that allows the inversion to be formulated based upon, and thereby outputting or calculating (step 107), petrophysical properties. Rock strength data may then be calculated from the petrophysical properties (step 109).

  • Publication number: 20190256623
    Abstract: Disclosed is a catalyst component for olefin polymerization. The catalyst component comprises magnesium, titanium, halogen and an internal electron donor. The internal electron donor includes an imine compound with a ketone group as shown in Formula I. Disclosed further is a method of preparing the catalyst component, and a catalyst for olefin polymerization containing the catalyst component. When the catalyst is used in olefin polymerization reaction especially propene polymerization reaction, the catalyst has a high long-term activity and good hydrogen response, and the obtained polymer has characteristics of an adjustable isotactic index and a relatively wide molecular weight distribution.

  • Patent number: 10064698
    Abstract: A dental drill head, constituted of a head housing, a wind wheel, and bearings, the head housing being constituted of a head housing cover and a head housing cavity, and the wind wheel being constituted of a wind wheel shaft and wind wheel blades. An anti-suck-back device is configured between the head housing cover and a wind wheel shaft end part to which the wind wheel shaft corresponds. The present invention, which adopts the aforementioned technical scheme, firstly makes it possible to reduce the intake in of contaminants when suck-back is taking place as the impeller is braked; and secondly, while there is still a positive pressure inside the head, the rubber head covering uses elastic force to brake the impeller and completely prevents the intake of contaminants. Moreover, the structure is simple and costs are low. Since the pressing area is reduced and the cavity is arranged between the rubber layers and the head covering, the teeth are less susceptible to touching the pressing portion.

  • Patent number: 10058398
    Abstract: A turbine dental drill mechanism, which includes a turbine and a turbine shaft. A balancing chamber is provided on the mechanism and includes an automatic balancing component provided therein. The automatic balancing component is a metal ball, sand grains or a flexible body. The metal ball in the balancing chamber can enhance the balance. The sand grains in the balancing chamber can reduce noise while also enhancing balance. The flexible body in the balancing chamber can eliminate noise and provide weight adjustment, thereby achieving automatic balancing.
