    摘要： An input/output processing module utilized for processing of signaling information and arranged in a central control unit of a local central office of a digital telecommunications system. Each central office further includes a central switching network and a plurality of trunks dedicated to common channel signaling each locally associated with a signaling link controller unit. Within the processing module, a microprocessor system is provided for initiating, starting and controlled resetting of transfers of signaling information under supervision of the central control unit. The signaling link controllers utilized for common channel signaling are residing on a separate signaling link bus. A signaling link bus control arrangement is connected to both the microprocessor system and the signaling link bus and includes programmable control means for sequentially executing transfer operations of signaling information. Interface means are independently accessible by both the microprocessor system and the control means of the signaling link bus control arrangement for enabling bi-directional data transfers between the microprocessor system and the bus control arrangement.

    摘要： A lubricating oil composition for internal combustion engines having superior rust and corrosion inhibition is disclosed. The composition comprises a major amount of a hydrocarbon oil of lubricating viscosity and a minor amount of conventional additives, including an overbased detergent (such as calcium carbonate or calcium hydroxide) for rust protection and an ashless dispersant (such as the reaction product of substituted succinic acid or anhydrides with amines). The composition also includes a supplemental rust inhibitor (SRI) additive which is a combination of an effective amount of a supplemental rust inhibitor (SRI) additive comprising a combination of (A) R.sub.1 O[C.sub.2 H.sub.4 O].sub.x H and/or R.sub.2 O[C.sub.3 H.sub.6 O].sub.y H with (B) R.sub.3 O[C.sub.2 H.sub.4 O].sub.x [C.sub.3 H.sub.6 O].sub.y H and/or R.sub.4 O[C.sub.3 H.sub.6 O].sub.y [C.sub.2 H.sub.4 O].sub.x H, wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are hydrocarbyl radicals selected from alkyl, aryl, alkaryl, and arylalkyl groups or combinations thereof having from about 10 to about 24 carbon atoms; and wherein x and y may vary independently in the range from 3 to about 15.
