摘要： Solid phosphoric acid (SPA) olefin oligomerization process units may be converted to operation with a more environmentally favorable solid catalyst. The SPA units in which a light olefin feed is oligomerized to form gasoline boiling range hydrocarbon product, is converted unit to operation with a molecular sieve based olefin oligomerization catalyst comprising an MWW zeolite material. Besides being more environmentally favorable in use, the MWW based zeolites offer advantages in catalyst cycle life, selectivity and product quality. After loading of the catalyst, the converted unit is operated as a fixed-bed unit by passing the C2-C4 olefinic feed to a fixed bed of the MWW zeolite condensation catalyst, typically at a temperature from 150 to 250° C., a pressure not greater than 7000 kPag, usually less than 4000 kPag and a space velocity up to 30 WHSV. The gasoline boiling range product is notable for a high level of branched chain octenes resulting in high octane quality.

摘要： Multi-mode diode emitters are stacked in a staircase formation to provide a spatially-multiplexed output. Improved coupling efficiency is achieved by providing tilted collimated output beams that determine an effective step height of the stepped structure. Since the effective step height is dependent on the tilt angle, a variable number of emitters can be used inside packages having a same physical step height, while still attaining high coupling efficiency.

摘要： An apparatus and accompanying methods for preventing telephone toll fraud that relies on the use of centralized voice verification to authenticate a party claiming a particular identity and requesting service, i.e. access to a telephone network. A voice verification intelligent peripheral (VVIP) (300) is interposed between, e.g., a tandem switch (40) and a voice service node (VSN) (250) both used to provide alternate automated billing service (AABS). The VVIP intercepts all call processing messages that occur between these two components and, at a pre-defined point during the processing of an AABS call, holds a call processing message, specifically a successful line information database (LIDB) query response message, until a voice verification of a caller is complete. While the message is held, the VVIP prompts the caller, who is claiming to be a subscriber, to speak a pre-defined password, obtains a voice template of the resulting speech and attempts to match this template against a template previously stored, within the VVIP, for the subscriber, during a prior enrollment process and for the same password. If the templates match and hence the identity claimed by the caller is confirmed, the VVIP simply passes the message, then being held, onward to its destination, such as the VSN, to then allow the normal processing for this call to proceed and eventually result in the call being extended through public switching network to a dialed destination number.
