Abstract: Busy/idle status information used for the selection of circuits for carrying interexchange telephone traffic between two exchanges, is recorded in an exchange with respect to routes, circuit groups within routes and circuits within the circuit groups. A route is defined as comprising all circuits between an exchange and a single adjacent exchange and selection of a circuit for the handling of a call is done by first selecting a direct or alternate route with reference to a route busy/idle map, selecting a circuit within a selected route with reference to a circuit busy/idle map, and finally selecting a circuit within a circuit group on the basis of circuit busy/idle information. The route and circuit group status maps are self-auditing in that a route is marked busy in the route busy/idle status map if it is determined that there is not at least one circuit group which has available circuits. Similarly, a circuit group is marked busy in the circuit group status map for a route, if it is determined that there are no idle circuits in a selected circuit group. The circuit busy/idle map is maintained by updating the map each time a circuit is seized or released, by call processing programs. A source destination restriction map is used in conjunction with the route status map to avoid the selection of routes which have been restricted with respect to a particular source. A second connection status map is used in the selection of alternate routes to avoid selecting an alternate route to an intermediate exchange which lacks available facilities to the original destination exchange.

Abstract: A combination pneumatic tire and integrated circuit transponder for tire identification. The transponder (24) is located within the tire structure and is capable of transmitting an identifying digital signal in response to interrogation by an R/F electric field emanating from outside the tire (22). The transponder (24) then transmits the identifying signal, which is received, conditioned and demodulated. The tire (22) has a steel-reinforced component, such as an annular tensile member (36) in its bead or a steel-reinforced ply. The transponder (24) has first and second electrodes (61,62), the first of which is positioned such that the average spacing of this first electrode's surface from one of the steel-reinforced tire components e.g. from steel cord ply (32) is substantially less than the average spacing of the second electrode's surface from such component. The transponder (24) is capable of transmitting the electrical signal from the tire (22) both prior to and after its vulcanization, thus permitting identification and control of the tire (22) during its manufacture and after its distribution and use.

Abstract: A input signal is received by a level shift circuit (41) to generate a plurality of level-shifted output signals (A, B,...,  A ,  B ,...) which have different shift amounts to each other. A switch circuit (42), selectively outputs the level-shifted output signals in response to a logic level of the input signal. The switch circuit selects a signal having a higher potential from the level-shifted output signals when the logic level of the input signal indicates a first level, and selects a signal having a lower potential from said level-shifted output signals when the logic level of the input signal indicates a second level.

Abstract: An injection molding manifold (10) for distributing pressurized melt from a common inlet (66) to thirty two outlets. The steel manifold has rear and forward plate portions (70,72) which are integrally brazed together. The rear portion (70) is drilled and plugged along a first transverse plane to provide the melt passage (64) with branches from a common inlet portion (76) to four intermediate portions (78). Four sets of matching grooves (84) are machined in the joining faces of the rear and forward portions (70,72) whereby each intermediate portion (78) of the melt passage (64) in turn branches along a second transverse plane to eight outlet portions, each leading to a cavity. The combination of the melt passage (64) branching in several different directions in two different transverse planes with the second plane having different sets of curved portions allows the melt passage to have a large number of outlets while still having smoothly curved bends without having a leakage problem.

Abstract: A data display display pager capable of automatically protecting a particular message over a limited period of time. The receiver stores a message signal in a message signal storage area included in control means thereof. When the pager detects out of the snored message signal protection information which is made up of a protection time signal indicative of a period of time for protecting the signal and a set of particular marks occurring before and after the protection time signal, it protects the message signal over the protection time. The message signal is protected in either of two modes which are discriminated from each other on the basis of the number or the kind of particular marks. During the protection time, the snored message (signal) is displayed in a first mode wherein a message without the protection information appears or in a second mode wherein the entire message appears, depending on the above-mentioned protection mode. on the elapse of the protection time, the stored message signal has, in a first protection mode, the protection information thereof deleted or has, in a second protection mode, only the particular marks thereof deleted.

Abstract: An accessory for an injection device comprises a protective shield 1 for surrounding the needle 2 and having inner and outer shield parts 3, 5 which are movable relative to one another from a contracted position, in which the point of the needle projects from the shield to enable an injection to be effected, to an extended position, in which the point of the needle is shielded by the shield. The shield is biased towards its extended position by a spring 8, and a locking tongue 25 within a cutout 26 in the wall of a collar 6 forming part of the outer shield part 5 is provided to lock the shield in its extended position and prevent the point of the needle from being exposed solely by application of pressure to the end of the shield in the direction of contracting movement. The locking tongue 25 is pivotable within the cutout 26 between a locking position and a disengaged position and is resiliently biased towards its locking position so that, during movement of the shield from its contracted position to its extended position, the locking tongue (25) overrides a shoulder 34 on the inner shield part 3 and, in so doing, is pivoted from its disengaged position into its locking position by resilient action so that it engages behind the shoulder 34 to retain the shield in its extended position. Such an arrangement permits reliable locking using only a weak spring.

Abstract: A modem device enabling a single communication line to be shared by a plurality of terminal units, and needing no switching operation between the terminal units on transmission. In transmission, when a transmission-start request is supplied from a terminal unit of any channel, the state of the other channels are checked. If these other channels are all in idle state, a channel selecting signal for selecting the channel corresponding to the transmission-start request is turned on so as to couple the corresponding terminal unit to a modem section for starting the transmission. In reception, on the other hand, upon receiving a call, priority calling channel information having been set in a predetermined mode register is read out to turn on a channel selecting signal for selecting the channel indicated by that information. As a result, a terminal unit of the channel corresponding to the channel selecting signal is selected to enable the receiving operation.
