Abstract: ABSTRACT      The present invention involves a process for separating components of a feed gas containing acid gases and hydrocarbons to form a CO2-rich stream, an H2S-rich stream and a hydrocarbon-rich stream.  Separation is achieved by initially passing the feed gas through a plurality of membrane separation units to produce a hydrocarbon stream and an acid gas stream.  The acid gas stream undergoes further separation to produce a CO2-rich product stream and an H2S-rich stream.  This process is especially adaptable for treating natural gas streams and gas streams resulting from enhanced oil recovery operations.

Abstract: ABSTRACT A radio channel control method for a narrow-zone mobile communication system in which a plurality of base stations share a plurality of channels and each selects any of the channels for setting up a call independently of the others, e. g. a portable telephone system or a cordless telephone system. Installed in each of all the base stations are transceiver, free to use all the channels, a device capable of identifying channels on which radio waves have reached the own station based on reception sensitivity, a device for selecting a channel, a device for transmitting a pilot signal and others, and a device for setting up a call. The channel for a pilot signal is adequately changed to shorten a duration of cochannel interference. Connection of multiple base stations to a single mobile station is eliminated by causing each base station to add to the pilot signal identification data which is particular to the base station.

Abstract: TWO LENS OPTICAL PACKAGE AND METHOD OF MAKING SAME             ABSTRACT OF THE DISCLOSURE           An optical package includes a first lens assembly and a second lens assembly aligned such that their optical axes are common.  The first lens assembly comprises a divergent light source disposed along the optical axis of a first lens such that the object distance is less than the focal length of the first lens.  The second lens assembly comprises a body, having a light acceptance angle less than the angle of divergence of the light source, disposed along the optical axis of a second lens such that the object distance is greater than the focal length of the second lens.  The assemblies are disposed such that the images formed by each assembly alone correspond in position along the common axis thereby coupling the light from the source into the body.          To fabricate the package, the source is placed within the focal length of the first lens and the body is placed outside the focal length of the second lens, forming first and second lens assemblies, respectively.  The assemblies are placed along a common axis such that a virtual image of the source, which would be formed by the first assembly alone, and a real image of the body, which would be formed by the second assembly alone, are aligned along the common axis.

Abstract: PEK/KC     ABSTRACT      METHOD AND APPARATUS FOR SYNCHRONIZING       ENCRYPTING AND DECRYPTING SYSTEMS     A synchronization method and corresponding apparatus for transmitting or storing encrypted data breaks the data into blocks and appends to each block an error detection code which is calculated from the encrypted data block plus a unique sequence number.  The sequence number is generated by a local counter and may be the number of bits, bauds, or characters transmitted and received since a previous resynchronization.  The error correcting code is transmitted or stored with the encrypted data block, but although the sequence number is appended to the data block for error code calculation purposes, it is not actually transmitted or stored with the encrypted data and error correcting code.  When the encrypted data is retrieved or received, the receiving apparatus appends to the received data blocks a sequence number derived from a local counter which is synchronized to the counter at the transmitting or storing apparatus and a new error detecting code is calculated for comparison to the error detecting code received or retrieved PEK/KC     with the encrypted data.  A mismatch between the error detecting codes indicates a transmission or synchronization error for that block.  In either case the data block can be retransmitted.
