Abstract: The present disclosure is directed towards methods of making titanium diboride products in various sizes. An aspect of the method provides (a) selecting a target average particle size for a target titanium diboride product; (b) selecting at least one processing variable from the group consisting of: an amount of sulfur, an inert gas flow rate, a soak time, and a reaction temperature; (c) selecting a condition of the processing variable based upon the target average particle size; and (d) producing an actual titanium diboride product having an actual average particle size using the at least one processing variable, wherein due to the at least one processing variable, the actual average particle size corresponds to the target average particle size.

Abstract: A method and an apparatus are disclosed that improve how an incoming call is handled across multiple data-processing systems, without some of the disadvantages of the prior art. Specifically, in a telecommunications call when a called telephone number is not associated with a particular in-service terminal, an enhanced terminating system of the call refrains from transmitting ringback to the calling terminal until an appropriate event occurs, such as the receiving of an asynchronous response from the auxiliary data-processing system to which the call has been directed. Depending on the response received, the terminating system might refocus the call or provide other treatment to the call. In some embodiments of the present invention, the terminating system also transmits a feedback signal to the calling terminal to provide status to the calling party on the progress of the call attempt, wherein the feedback signal is different than the ringback signal.

Abstract: An apparatus and methods are disclosed that enable a user to access a telecommunications feature of a private branch exchange (e.g., call forwarding, automatic callback, etc.) by calling, from an off-premises telecommunications terminal, a telephone number that routes to the private branch exchange and that corresponds to the feature. When the telephone number is called, the corresponding telecommunications feature is activated or deactivated, as appropriate. For example, calling “555-1111” from might activate automatic callback, and calling “555-2222” might deactivate automatic callback.

Abstract: A method is disclosed that enables a data-processing system, such as a private branch exchange, to detect and disconnect looping communication channels, without some of the costs, disadvantages, and limitations of techniques in the prior art. The illustrative embodiment of the present invention provides detection of looping communication channels at the point where the loop begins. By detecting at the beginning point of the loop, the illustrative embodiment has the advantage of de-allocating call resources sooner than some techniques in the prior art. This enables the call resources to be reused faster for subsequent incoming and outgoing calls. Faster reuse is advantageous because it can lower the call blocking characteristic, which is related to the probability of a new call not being set up due to lack of communication channel resources.

Abstract: A fuel system adjustment tool includes an elongated shaft and a rotatable rod disposed within the shaft. At one end of the rod is a drive that operably fits to an adjustment point on a carburetor. At the other end is a rotatable knob that produces a tactile engagement or clicking sensation at selected degrees of rotation, preferably every 180 degrees of rotation. The engagement is produced by a collar having a notch therein on the end of the shaft, and spring loaded balls in recesses on the interior of the knob. As the knob is rotated, one of the balls falls into the notch at the selected degree of rotation, but is releasable from the notch upon further rotation.
