Abstract: A device and method for correcting for timing jitter of an optical data pulse in an optical transmission system. During transmission data pulse may suffer jitter. Its arrival time at a node may be temporally offset from its predicted arrival time. Data pulses are timed so that they may be received at a detector disposed downstream of said node at a predetermined time. The device including a source of chirped optical pulses and a node, which has a first input arranged to receive a chirped optical pulse, the node having a second input arranged to receive a data pulse. The node including an optical gate arranged to generate an output pulse in response to said first pulse and said data pulse received at said first and second inputs, respectively, having a wavelength dependent upon the time t at which said data pulse is received at said second input. The device further including an optically dispersive medium after passage through which, the output pulses are correctly retimed.

Abstract: A wall plate for attaching a structural beam to a masonry wall is disclosed. The wall plate has a flat plate having at least two bolt holes and an absence of nail holes therethrough. At least one anchor is fixed to the flat plate and extends from one side of it.      Means are welded to that side which have at least two threaded apertures therethrough, where each aperture is'aligned with a bolt hole. There is a removable covering over the means.      Methods of using the wall plate are also disclosed. To make a precast concrete panel, one or more wall plates are attached by any suitable means to the inside of forms at the positions required to bolt the resulting panel to structural beams and concrete is poured into the forms. After the concrete has set, the precast concrete panel is transported to the building construction site and is positioned so that an angle connector can be bolted to the wall plate and to a structural beam. If the masonry wall is made of laid concrete blocks, concrete is poured into the top of blocks and the wall plate is pressed horizontally into that concrete. Structural beams can then be bolted to the wall plate.

Filed: 2000-11-28
Abstract: Various equivalent adaptive audio matrix arrangements are disclosed, each of which includes a feedback-derived control system that automatically causes the cancellation of undesired matrix crosstalk components in the matrix output.  Each adaptive audio matrix arrangement includes a passive matrix that produces a pair of passive matrix signals in response to two input signals.

Abstract: Thin steel strip (11) is passed through a pinch roll stand (12) comprising pinch rolls (13) to a hot rolling mill (16) comprising work rolls (17) and backing rolls (18). In advance of rolling mill (16) the strip passes over support rolls (15). An anti-crimping guide roll (21) located immediately in advance of the rolling mill (16) is mounted on a pair of rocker structures (22) so as to be raisable from a lower inoperative position to lift the strip out of a straight line path so as to pass around the anti-crimping roll and to be wrapped about the upper work roll (17) in advance of the nip (26) through an angle of wrap of at least 10°. Due to the wrapping of the strip around the upper work roll, (17), that roll supports the strip and resists buckling of the strip and the generation of crimping defects.
