Abstract: A joint for connecting a tip member to the end of a rod or shaft (12). The joint is particularly useful for joining a rod end (14) to a tip member (38) of a material which is not easily brazed, cemented or otherwise adhesively joined together. In the specific example described, a ceramic tip is jointed to the end of a metal rod (12), such as in a plug, a globe, or sliding stem valve. A cavity (36) in the interior of the tip member (38) has a narrowed opening (48) at its top which terminates at a flat surface of the tip member (38). A pair of wedge members (26), each of about 180 degrees annular extent, and the headed bolt end (14) are all located in the cavity, with the wedge members (26) oppositely positioned around bolt head (20). The bolt head (20) and wedge members (28) have complementary tapers so that motion of the bolt away from the tip member (38) cavity causes the wedge members (26) to move radially away from each other and preferably contact the side wall of the cavity (36), with the cavity being partially closed by an annular overhang through which the bolt shank passes. The other end of the bolt (16) is threaded and is received by a threaded hole (18) in the end of the rod (12). The face (14) of the rod (12) is in surface contact with the surface (50) of the tip member (38).

Abstract: In apparatus for testing memory in a computer, without involvement of the processors which are used by the computer to run its programs, the testing is done by a testing circuit which multiplexes into the data and address buses leading to memory. When operative, the testing circuit first writes a test word to all memory addresses. Then the testing circuit reads each address, and checks for accuracy. If an error is found, the address of the error is stored. In a computer with multiple memory boards, a separate testing can proceed substantially simultaneously (and asynchronously), thereby enabling the testing procedure to be completed rapidly.

Abstract: A clock synchronization system for synchronizing the performance of a number of clocks (46) so that they run parallel with a reference clock is disclosed. Each clock of this synchronization system includes a counter (52) that indicates the current time and that is sequentially incremented by a counter advance signal applied thereto. A time counter controller (54) both initializes the counter and generates the clocking signal that controls the advancement of the counter. The time counter controller further monitors the time indicated by the counter and compares it to a reference-time signal received from a reference clock. Based on the comparison, the time counter controller selectively reinitializes the counter and adjusts the rate at which the clocking signal is applied to the counter so as to ensure that the counter advances at a rate equal to the rate at which the reference clock advances. In some versions of the invention, the comparison of the reference-time signal to the actual clock counter time is made at a maintenance operation point (58) remote from the clock. In these versions of the invention, the maintenance operation point reports the difference in the two times back to the time counter controller, which, in turn, makes the appropriate adjustments to the counter and to the clocking signal.

The digital logic circuit includes a pull-down device coupled to an input line. The digital logic circuit further comprises a weak pull-up device and a strong pull-up device coupled to the pull-down device at a node. A means for providing a signal on an output line of the programmable logic device is coupled to the pull-down device and the pull-up devices. The weak pull-up device holds the node high if the pull-down device is in an off state. However, if the pull-down device is in an on state, the strong pull-up device is also turned on, thereby providing a stable intermediate voltage on the node. A feedback path from the output line controls the state of the strong pull-up device.
