Abstract: ABSTRACT OF THE DISCLOSURE            Sync extraction for a broadcasting system with time multiplexing of digital and analog signals In a broadcasting system with time division multiplexing of digital signals containing a synchronisation pattern and analog signals, sync extraction is achieved with a process including detecting the extreme values of the signals to be subjected to decoding, after they have been amplified with a gain G, with a time constant compatible with the low cut off frequencies to be accomodated; the gain G is controlled as a decreasing function of the difference between the extreme values with a time constant greater by several orders of size than the repetition period of the multiplex; before decoding and determination of the extreme values, there is added to the amplitied signal a DC component which is a decreasing function of the sum of the extreme values, until the retrieval of the clock signal then identification of the synchronisation pattern downstream of the coding.

Abstract: SURGICAL STAPLING INSTRUMENT WITH            STAPLE HEIGHT ADJUSTING MECHANISM     Abstract A surgical stapling instrument suitable for performing a gastrointestinal anastomosis is provided.  The stapling instrument incorporates a staple height adjusting mechanism which enables the gap between its jaw members to be adjusted to select different staple heights to be produced when the staples are formed.          Preferably, the stapling instrument includes a pair of elongate jaw members, one of which supports a staple cartridge adapted to receive at least two laterally spaced longitudinal rows of staples, and the other provided with an anvil adapted to form the staples.  A pusher bar and knife assembly slidable longitudinally relative to the jaw members sequentially drives the staples from the cartridge and forms the staples against the anvil to produce a pair of laterally spaced rows in the tissue.  The pusher bar and knife assembly includes a knife blade for cutting the tissue along a line between the longitudinal staple rows.  A set of jaw support members is carried by the knife blade which travel along the elongate jaw members as the pusher bar and knife assembly is advanced to provide local support to the jaw members.  The angular orientation of the knife blade relative to the jaw members is adjustable by the staple height adjusting mechanism to vary the vertical spacing between the jaw support members as the gap between the jaw members is varied.

Abstract: ABSTRACT OF THE DISCLOSURE   An electrical outlet box optionally having in com-bination therewith, a connector fitting for connecting a corrugated conduit to the box, the box having a back wall and at least one side wall of synthetic resin.  A pressure removable plug is displaced out of the plane of the side wall so as to provide a precisely delineated zone of weakness surrounding the plug.  When one preferred type of connector fitting is used in combination with the box, a wedge-shaped end portion of the fitting, having a relatively small surface area, is manually pressed against the pressure removable plug along a pressure zone immediately radially inwardly from the zone of weakness.  This pops the plug out of the wall of the box, leaving a neat, smooth hole into which the connector fitting may be inserted by continued manual pressure applied thereto.  The connector fitting includes an expandable cylindrical body portion, and further includes an external circumferential groove at the intersec-tion of the cylindrical body portion with the wedge-shaped end portion.  The edge of the wall which defines the opening formed on removal of the plug snaps into this groove to interlock the connector fitting in the wall of the box.

A number of secondary inlet ports are disposed along and pass through the duct into the ducted area, for drawing in water to minimize cavitation along the ducted area. In an alternative embodiment, there is also a second duct coaxial with and surrounding the first duct, thereby creating a second ducted area.  The second ducted area has a water inlet near its proximal end and a water outlet near its distal end, the ducted area being tapered from inlet to outlet.  At least one helical screw is provided along the first duct in the second ducted area, and the first duct is connected to the main shaft so that the first duct rotates with the main shaft.
