Title: Process for manufacturing olefins using a pentasil zeolite based catalyst
Inventor: KAMINSKY MARK P
IPC: C10G11/05
Filed: 1999-09-28
Abstract: A catalyst and an improved process for producing olefins by catalytic naphtha cracking are described. The process provides relatively higher yields over a commercially important range of naphtha conversion, while providing about the same or lower yields of aromatics and methane over the range. In the process, a hydrocarbon naphtha feedstock including a hydrocarbon having about three to about twenty carbon atoms per molecule is passed into a reactor containing a pentasil zeolite catalyst. The catalyst includes about 0.1 to about 10 weight percent phosphorus and about 0.1 to about 10 weight percent of a promoter metal selected from the group consisting of gallium, germanium, tin and mixtures thereof. The hydrocarbon may be passed into the reactor together with a diluent selected from the group consisting of steam, nitrogen, methane, and ethane and mixtures thereof. Alternatively, the hydrocarbon may be passed into the reactor together with additional propane.

Title: Wireless communications methods and apparatus employing paging attribute descriptors
Inventor: RAITH ALEX KRISTER
IPC: H04W68/00
Filed: 1999-11-09
Abstract: A paging attribute descriptor (PAD) indicates the content of a page message is transmitted in a first time slot and/or a succeeding second time slot of a physical channel, and the page message is transmitted in the second time slot.  The second slot may be, for example, a Digital Control Channel (DCCH) slot mapped on a physical channel (DTCH) of an IS-136 system. The transmitted PAD  is recovered at wireless station, which then determines whether to recover the page message based on the recovered PAD, e.g., if the PAD indicates that the page message is an empty page message, a page message addresed to another wireless station or a page message that includes control information that has changed. For example, in an IS-136 compliant system, the PAD may be transmitted in the coded superframe phase (CSFP) field of a Paging Channel (PCH) message transmitted in a Digital Control Channel (DCCH) slot, or in reserved bits of a slot preceding a PCH message.

Abstract: A strap path guide cover, comprising part of the outer housing cover of a strapping machine, is pivotally mounted such that it may be rotated away from the housing of the strapping machine to expose a strap path. The cover defines parts of numerous elements of the strap path created through the head of the strapping machine. The cover defines a number of openings for cooperatively engaging corresponding alignment pins extending from the head, such that alignment of the cover, and thus the strap path, is made accurately and easily. The cover may be rotated down for cleaning of jams and debris from the strap path, and may be rotated to a first position, aligning the strap path, for a rapid return to use. The present invention further defines an upper strap path guide cover which also pivotally opens to allow for cleaning of the upper path and pivotally closes in alignment.

Abstract: In a method for an automatic message transfer service, at least one message is stored in a message service center MSC through a telephone company and is sent to a Web terminal of a user from the MSC. The automatic message transfer service is registered by each user as a result of a contract with the telephone company. The Web terminal is connected to the MSC through INTERNET. The Web terminal makes access to the MSC through the INTERNET and obtains an authentication of the automatic message transfer service. The MSC sends only storage data related to the stored messages destined to the registered user. The Web terminal displays the received storage data of the messages on a screen by letters, selects the storage data for one of the messages, and notifies the MSC of the selected storage data.      The MSC receives the selected storage data and sends the message itself corresponding to the received storage data to the Web terminal.

Title: Wavelength-dependent optical signal processing using an angle-to-offset module
Inventor: IYER RAJIV
IPC: H04J14/02
Filed: 2001-11-20
Abstract: An optical device comprises a dispersion element, a reflector, and an angle-to-offset (ATO) element. The angle-to-offset (ATO) element has optical power. The dispersion element is positioned in or near a focal plane of the ATO element and adapted to separate an input wavelength division multiplexed (WDM) light beam received from an input port of the optical device into two or more channel light beams. The reflector is positioned in or near a focal plane of the ATO element and arranged to receive the channel light beams from the dispersion element via the ATO element. The reflector is designed to reflect at least one of the channel light beams toward a respective output port of the optical device. With this arrangement, the dispersion element, reflector and ATO element cooperate to optically demultiplex the input WDM light beam. Additional optical elements arranged in the propagation path between the reflector and the output port(s) and/or between the input port and the dispersion element can be used to provide further optical signal processing functionality such as dynamic channel equalization, add drop, or wavelength switching.
