Abstract: - 11 - I. VAN DE VOORDE-D. MESTDAGH-G. VAN DER PLAS-C. SIERENS                         W.VERBIEST 2-7-5-5-9 ABSTRACT             OPTICAL TRANSMISSION SYSTEM      The system includes two transmitters (T1, T2) and two receivers (R1, RZ).  One transmitter (T1) includes a wavelength tunable laser, sending an FSK optical signal (OS1) which has a constant intensity.  In a first receiver (R1) this FSK optical signal (OS1) is transformed into an IM signal (OS1')  by an optical pass band filter.  This IM signal (OS1') is then detected by a first direct detection receiver (DM).  In a second direct detection receiver (R2) the FSK optical signal (OS2) is not detected, since it has constant intensity.  A second transmitter (T2) includes a Fabry Perot laser or a LED with a broad linewidth, sending an IM optical signal (OS2)  This IM optical signal (OS2) is detected by the second direct detection receiver (R2).          It is not detected by the first direct detection receiver (DM), because it is strongly attenuated when passing through the narrow bandpass optical filter (TM) before being applied to the first direct detection receiver.  This system is especially advantageous in bidirectional optical transmission systems, due to its inherent insensitivity for reflections.

Title: Phase combining method and apparatus for use in a diversity receiver
Inventor: LAROSA CHRISTOPHER P
IPC: H04B7/26
Filed: 1992-08-26
Abstract: A phase combining method and apparatus for use in a diversity reception radiotelephone is described. The phase combining method and apparatus is a hybrid diversity technique which combines elements of maximal ratio combining (MRC) and level comparison selection diversity, which results in a simple and effective implementation of a diversity receiver with superior performance. The diversity receiver demodulates the received signals (115, 117), extracts the phase, forming two phase signals (209, 211). Then, the two phase signals (209, 211) are combined to form a third phase signal (213). One of the three phase signals is selected to be used for interpretation of a symbol in the Quadrature Phase Shift Keying (QPSK) constellation. The selection process is based on the received signal strength of the received signals.

Abstract: ABSTRACT      A latch assembly is disclosed which is mounted in an aperature formed in a first member and adapted for developing a compressive force between the first member and a corresponding second member for releasably retaining the first member against the second member and in a latched position.  The latch assembly includes a housing which is received within the aperature of the first member and includes an aperature extending therethrough.  A slide is included which is received and projects through the aperature of the housing for movement axially and rotatably therein.  A pawl is also provided on the slide which is adapted for axial and rotatable movement corresponding with movement of the slide for releasably retaining the second member.  A handle is pivotally attached to the slide for facilitating movement of the slide and pawl axially as the handle is pivoted between closed and opened positions.  The pawl engages the second member in the latched position when the handle is pivoted to its closed position.  The handle is also adapted for movement in a direction generally along a longitudinal axis thereof upon the closing and the opening of the handle.  The horizontal movements of the handle enable a first end of the handle to be positioned proximate to the housing when the handle is in its closed position.  In the opened position, the handle is rotatable for facilitating rotatable movement of the pawl via the slide away from the second member and into an unlatched position.  A sealing and biasing member is also included which provides both sealing of the aperature in the housing so as to prevent the passage of matter therethrough and for biasing the slide axially downward so as to urge the handle into contact with the housing upon its pivotal movement. A cam member including an integral spring member can also be included for preventing extraneous rattle of the handle and also to assist in motion control during movement thereof.

Patent CA-2106686-A1 (CA)
Title: Pipe fitting
Inventor: SMITH TREVOR R
IPC: F16L33/22
Filed: 1992-03-18
Abstract: A pipe coupling comprising a tubular spigot (1) for insertion into the end of a pipe (8) and a sleeve (7) for positioning over the end of the pipe (8) into which the spigot (1) has been inserted.  The outer surface of the spigot (1) defines a series of circumferential ribs (4) separated by circumferential grooves (5). When the coupling is assembled the sleeve (7) traps the pipe end (8) against the spigot (1) such that the ribs (4) are pressed into the inner wall of the tube and material displaced by the ribs (4) is pressed into the grooves (5). The mean cross-sectional area of the space defined between the radially outer surface of the spigot (1) and the radially inner of the sleeve (7) in the assembled coupling reduces from the end (2) of the spigot which is first inserted into the pipe. Thus, the compression of the pipe end (8) increases towards the end of the pipe, ensuring that relatively thick walled pipes are tightly gripped close to the spigot end (2) whereas relatively thin walled pipes are tightly gripped by the ribs (4) and grooves (5) remote from the spigot end (2).

Abstract: TUBULAR GUIDE AND SUPPORT SYSTEM             Abstract A length of elongate material  such as  rubber hose (120) is supported and guided while being fed along a desired path of travel (108) that extends through the hol-low interior of a tubular structure  (100).  The tubular structure  (100)  mounts an  array  of  relatively  closely spaced rollers (225) that project into the hollow interior to guide and support the moving length of material (120). The tubular structure (100) is formed as a "tube within a tube"  assembly  of  "outer" and  "inner"  tubular  members (130, 140) that closely interfit, and that sandwich roller support pins 1195) between overlying portions of the outer and inner tubular members (130, 140).  The roller support pins (195) bridge roller positioning holes (145) that are formed through the inner tubular member (130) at an array of  spaced  locations.   The  rollers  (225)  are  rotatably mounted by the support pins (195) and project through the positioning holes  (145)  into the hollow interior of the tubular structure (100)  to engage outer surface portions of such elongate material  (120)  as is being fed through the tubular structure (100) to prevent the moving material (120) from contacting stationary portions of the tubular structure  (100).   In preferred practice,  a  funnel-like roller-carrying end assembly  (250)  is provided near one end of the tubular structure (100) to define a constricted discharge opening (286) through which the moving material (120) discharges.
