Abstract: PROCESS AND APPARATUS FOR IMPROVING THE DISTRIBUTION  ON A RECEIVING DEVICE OF FIBERS CARRIED BY A GAS CURRENT     ABSTRACT OF THE DISCLOSURE     The invention relates to the distribution on a receiv-ing device of fibers carried by a gas current, To improve the distribution, the gas current carry-ing the fibers is subjected to the action of a gas layer which envelopes the current and of which the direction of flow in a plane tangent to the gas current differs from that of the gas current.  The action of the gas layer results in an expansion of the current carrying the fibers.     The invention is particularly useful where the fibers are received on a collecting device such as a foraminous conveyor belt, of large width.

Abstract: ABSTRACT OF THE DISCLOSURE           A circuit for boosting digital data signals in a telemetry system for sensing remote physical events and for transmitting and boosting a digital data signal representing the sensed events on a transmission line.  The telemetry system comprises a master clock and a plurality of sensing stations for, sensing local data.  The sensing stations inject local data onto the transmission line as a digital data signal, and a con-troller/receiver receives the digital data.  The master clock initializes the system timing and generates a sync signal.  Each sensing station includes a booster subsystem for receiving the local digital data and for injecting the digital data onto the transmission line as a digital data signal.  During system start-up, each booster subsystem claims a slot, in accordance with an organizational process, for injecting the digital data signal onto the transmission line.  The booster sub-system in each sensing station further includes a boos-ter circuit for boosting the digital data signals which are propagating on the transmission line, as well as the sync signal.  The booster circuit comprises a nega-tive impedance bistable device for enhancing the ampli-tude and rise time of the digital data signal.  Each booster subsystem further includes a switching mode regulator circuit for converting a supply current on the transmission line to a level voltage, thereby pro-viding local power to the components of the sensing sta-tion.
