Title: Gas management system for closely-spaced laydown jets
Inventor: MARSHALL LARRY R
IPC: B65H54/16
Filed: 1991-08-21
Abstract: An improvement is disclosed for reducing or even preventing interferences or interactions between adjacent, closely-spaced laydown jets utilized in a fibrous sheet laydown process. The improvement comprises positioning an inverted "V-shaped" baffle between adjacent, closely-spaced laydown jets so that the turbulent gas streams produced by each laydown jet are diverted and vented away from the area of sheet laydown on a moving collection belt. The baffle vents the fountain of gas produced by the collision of adjacent laydown jets in a cross-direction to that of the direction of belt movement.

Abstract: In an adaptive filter formed by first through N-th delay elements connected in series to one another to define first through N-th taps, first through M-th coefficient circuits which are smaller in number than the delay elements and which produce first through M-th coefficient signals together with first through M-th calculated signals, an adder for summing up the first through the M-th calculated signals to produce an echo replica signal, and a subtractor for subtracting the echo replica signal from an echo signal to produce an error signal, a matrix switch circuit is arranged between the first through the N-th taps and the first through the M-th coefficient circuits and is controlled by a control circuit to adaptively select, from the first through the N-th taps, first through M-th taps connected as active taps to the first through the M-th coefficient circuits.  The control circuit supplies the matrix switch with a matrix control signal which includes active tap numbers assigned to the active taps.  A plurality of the active taps may be replaced by changing a replacement time interval determined by the control circuit with reference to a result of monitoring the error signal or the coefficient signals.  Alternatively, the control circuit can change an initial assignment to the first through the M-th taps from one to another when a dispersive portion of an impulse response has not been searched out for a long time.  On the other hand, the control circuit concentratedly sets the active taps once the dispersive portion has been found out by monitoring a maximum absolute value of the first through the M-th coefficient signals.

Inventor: HENSON GORDON D
IPC: G02B6/38
Filed: 1991-05-14
Abstract: A compact optical fiber distribution center has a housing provided by a pair of stackable containers. One container encloses a fiber connector zone in which a plurality of card-like modules are slidably mounted, normally aligned in single file, and each extending vertically when the distribution center is in use. The other container has a jumper routing zone at the front, a fiber routing zone at the rear, and an intermediate fiber storage zone which is divided by partitions, each of which is aligned with a space between adjacent modules. Each module carries a row of optical fiber connectors. At one side of the housing, the rear ends of the connectors can be connected to optical fibers of one or more feeder cables, and at the other side, the rear ends can be connected to optical fibers of one or more distribution cables. The front ends of the connectors at said one side can be connected by optical fiber jumpers to the front ends of connectors at said other side, thus interconnecting any feeder fiber with any distribution fiber. Easy access to the connectors is afforded by sliding individual modules out of the single file toward a front or a rear opening in the housing, which openings are closable by hinged doors.
