Ceramic slurries with photoreactive-photostable hybrid binders
Ceramic slurries may include ceramic particles, a photoreactive-photostable hybrid binder, and a photoinitiator. The photoreactive-photostable hybrid binder may include a photoreactive organic resin component, a photoreactive siloxane component, and one or more photostable siloxane components. Methods of forming a ceramic part may include curing a portion of a ceramic slurry by exposing the portion of the ceramic slurry to light to form a green ceramic part, and partially firing the green ceramic part to form a brown ceramic part. The brown ceramic part may be sintered at or above a sintering temperature of the ceramic particles to form a ceramic part, wherein sintering includes heating the brown ceramic part to a sufficient temperature to promote reaction bonding that converts silica from the photoreactive-photostable hybrid binder into silicates that bond with the ceramic particles.
Systems and Methods for Enabling Communication Between USB Type-C Connections and Legacy Connections Over an Extension Medium
Techniques for supporting USB and video communication over an extension medium are provided. In some embodiments, an upstream facing port device (UFP device) is coupled to legacy connectors of a host device, and a downstream facing port device (DFP device) is coupled to a USB Type-C receptacle of the sink device that may provide both USB and DisplayPort information. The UFP device and DFP device communicate to properly configure the USB Type-C connection for use in the extension environment. In some embodiments, a source device is coupled to the UFP device via a USB Type-C connection, and legacy video and USB devices are coupled to the DFP device. The UFP device and DFP device again communicate to cause the source device to properly configure the USB Type-C connection for use in the extension environment.
Systems, devices, and methods for manufacturing carbon ceramic brake discs
Systems, devices, and methods are provided for manufacturing a carbon ceramic brake disc. Generally, a plurality of uncured or partially-cured bulk molding compound preforms or molding compound layers and ventilation cores are placed in a mold cavity and warm-pressed at a first temperature. The ventilation cores are removed from the resulting cured green body. The cured green body is then removed from the mold, and treated through a polymer infiltration and pyrolysis or reactive melt infiltration process. Certain steps can be repeated until a desired target density or weight is attained.
MOULD FOR THE MANUFACTURE OF CERAMIC PACKING MEMBERS
A mould for manufacturing a packing member from a liquid ceramic composition. The mould including a first part and a second part, wherein the first part and/or the second part comprise an open mould cavity and wherein the first and second parts are operable to engage to form a closed mould cavity, wherein the mould further includes a reservoir forming member, and wherein the mould is operable to be moved from an open position in which the first and second parts are at least partially spaced such that the reservoir member forms a reservoir cavity and the mould cavity is open, to a partially closed position in which the location of the reservoir cavity has moved with respect to the mould cavity and/or the volume of the reservoir cavity has reduced, and then to a closed position in which the first and second parts are engaged such that the mould cavity is closed.
