  • Publication number: 20200309633
    Abstract: A die casting machine melt leakage detecting device includes a pulling wire, multiple wire winding columns, a wire fixing member, an elastic wire connecting member and a trigger switch. The pulling wire is capable of withstanding temperature outside a mold during normal die casting and is melted and broken after making contact with molten metal. The multiple wire winding columns are arranged around the mold, an end of the pulling wire is connected with the wire fixing member, and another end of the pulling wire is sequentially wound around the wire winding columns and is connected with the elastic wire connecting member. The elastic wire connecting member is opposite to the trigger switch, the elastic wire connecting member is in a compressed or stretched state when the pulling wire is kept tensioned in the operating state.

  • Patent number: 10737885
    Abstract: Provided is an automatic compensation, balancing and tensioning conveying chain wherein the conveying chain can automatically adjust the guide rails to extend and retract and be automatically tensioned and balanced to avoid the influence on the conveying efficiency of the conveying chain due to the slack of the conveying chain. In addition, the guide rail position maintaining components provide a reverse compensation force to the telescopic guide rail when the guide rail pre-warning limiting switches are triggered, so as to reduce the imbalance of movements of the sliding trolleys and avoid a situation that the sliding trolley may trigger an extreme position signal in advance to cause a false alarm and stop the entire conveying chain, thereby guaranteeing a dynamic balance of two tensioning stations and completely eliminating an elasticity change of the chain.

  • Publication number: 20200136333
    Abstract: A compliant pin pre-screening, guiding and quality monitoring apparatus is provided. The compliant pin pre-screening, guiding and quality monitoring apparatus includes a fixed plate, a movable plate, a printed circuit board (PCB) and a press-fit connector. The fixed plate defines a through-hole and is disposable above a working table. The movable plate is disposable to be urged by a bias against a first surface of the fixed plate facing the working table and includes pin extendable through the through-hole. The PCB defines a via and is disposable on a second surface of the fixed plate opposite the first surface whereby the pin is extendable through the via with the via corresponding in position to the through-hole and the pin. The press-fit connector is disposable to be secured in position proximate to the PCB and to be inserted into the via with guidance provided by the pin against the bias.

  • Patent number: 10521581
    Abstract: Systems, methods, and apparatus for authenticating and authorizing clients. A client certificate is used to authenticate and authorize a client (or user). When the client certificate is received, the certificate is authenticated. If the certificate is valid, a username included in the certificate is used to authorize the client. This may be done based on privileges or permissions associated with the user name. Once the client or user is authenticated and authorized, operations requested by the client can be performed as long as permitted by the privileges or permissions.
