Abstract: A gutter cleaning system and device for suctioning debris from a gutter mounted on a house or building above ground level for use with a vacuum cleaner and tubular hose extending from the vacuum cleaner comprising a first hollow tubular conduit having a curvilinear shape, a second hollow tubular pipe having a curvature forming a bend of above zero and less than ninety degrees with the second tubular pipe having one open end adapted to be joined to the first hollow tubular conduit and an opposite open end adapted for placement into the gutter to be cleaned and further comprising a manually adjustable locking mechanism and fitting with the locking mechanism and fitting having a first position for interconnecting the first and second pipes to one another at a fixed angular orientation relative to one another and having a second position for disengaging the first and second pipes from one another thereby permitting the angular orientation of the first and second pipes to be manually adjusted into another position

Abstract: A terminal adapter for a telecommunication network having a receiver for multiple HDLC communication channels. The receiver includes a BCC calculator for computing and checking the validity of a received HDLC CNM frame. The terminal adapter further includes a device for detecting the reception of a specific CNM header included in a CNM frame on any of the HDLC communication channels and responsive to the detection for setting the BCC calculator to a predefined state. The latter state corresponds to the state of the BCC calculator after a computation of BCC for the specific CNM header. Therefore the BCC calculator can proceed with computation of said BCC for the CNM frame.

Abstract: A coding process, given a total number of available bits per unit time, allocates to each of a plurality of signal channels a number of bits proportional to information in the channel. The process is useful for transcoding BCPCM (Block Coded PCM) voice signals for lower bit rate and conserving transmission channel bandwidth.
