Title: On-machine-seamable multi-axial press fabric
Inventor: YOOK STEVEN S
IPC: D21F1/00
Filed: 1999-01-08
Granted: 2001-06-07
Abstract: An on-machine-seamable multi-axial press fabric for the press section of a paper machine is made from a base fabric layer assembled by spirally winding a fabric strip in a plurality of contiguous turns, each of which abuts against and is attached to those adjacent thereto.

Crosswise yarns are removed from each turn of the fabric strip at the folds at the widthwise edges to produce seaming loops. The first and second fabric plies are laminated to one another by needling staple fiber batt material therethrough. The press fabric is joined into endless form during installation on a paper machine by directing a pintle through the passage formed by the interdigitation of the seaming loops at the two widthwise edges.

Title: Improved high dynamic range optical receiver preamplifier
Inventor: GU ZHONG-QIANG
IPC: G02B6/00
Filed: 1999-02-09
Granted: 1999-09-21
Abstract: The present invention relates to two counter parallel diodes added at the input end of a preamplifier and connected in parallel with a transimpedance feedback resistor. The invention can provide a current path for passing a signal when the voltage exceeds the threshold of diode because of an excessive input current signal to resolve problems such as varying charge-discharge time and change of working period resulting from an excessive signal. Additionally, two counter parallel diodes enable diodes to work with large current signals in two input modes (cathode or anode). Thus the invention can increase the dynamic range of a transimpedance preamplifier. Additionally, a resistor of low resistance connected in series between the input end and the feedback network can reduce the effect in bandwidth and stability from contact surface capacitance produced by said two counter parallel diodes, especially in high-speed applications, to increase the resistance of the resistor connected in series.
