IPC: B01D27/02
Filed: 1996-07-10
Abstract: A method and apparatus for continuously finishing hot-rolling steel strips includes partially joining a rear end of a preceding steel strip and a leading end of a succeeding  steel  strip  after  the  strips  have  passed through a rough hot-rolling step.  The joint is flattened.          The joint is rolled with a first stand of a tandem rolling mill.   The mill is provided with a plurality of stands that includes a pair of work rolls and backup rolls and/or intermediate rolls, so that a compression stress acts at the unjointed section of the strips in the longitudinal direction  of  the  joint  while  tracking  the joint.          Shape-control-rolling is performed on the  joint with a second and succeeding stands so that a section of the steel  strip other than the  joint  is  subjected to the shape-control-rolling at all the stands.

Abstract: A safety rail attachment for a bath tub includes a post with a rail assembly which is mounted within the post for rotation relative to the post through four separate 90 degree positions with the rail assembly latched in each of the four positions as required by the user.  The post is clamped to the side wall of a bath tub by a clamping assembly formed by a pair of clamping plates which are squeezed together by a pair of parallel squeeze rails which bridge the side wall at positions spaced along the length of the side wall and spaced apart along the width of the clamping plates. The clamping plates are attached to the rails by welded tubular members with a post being mounted on of the clamping plates by the same tubular members.  The clamping plates and the tubular members are covered by attractive cover panels including an inner cover panel and an outer cover panel.  Each of the cover panels has a horizontal wall bridying the side wall of the bathtub and covering the clamping assembly.  Inside the inner panel is the vertical which extends downwardly over the clamping plate with side surfaces extending into contact with the side wall of the bathtub.  Similarly the outer panel has a vertical wall and side walls that extend into contact with the outer part of the bath tub.  The inner panel has a hole in the horizontal surface receiving the post.  The outer panel overlaps with the inner panel and can slide inwardly and outwardly to accommodate adjustment of the width of the clamping assembly.

Abstract: An apparatus (40) for folding a fibrous insulation batt (12) having a length and a width is disclosed. The batt has first and second sections (22, 24), where each section is approximately one half the length of the batt. The apparatus comprises a lower conveyor (50) for conveying folded batts in a first direction (52), and an upper conveyor (60) which is positioned above the lower conveyor and moves in the first direction to define a folded batt exit path (77). The apparatus further comprises a folding member (64) for folding the insulation batt, where the folding member is adapted to contact the batt across its width. The folding member is mounted for movement to initially push the batt in a second direction (76), and then subsequently push the batt in the first direction, thereby pushing the batt along the folded batt exit path. The movement of the folding member folds the batt so that the first section (22) of the folded batt is generally parallel to and contacting the second section (24).

Patent CA-2214624-A1 (CA)
Inventor: TAKEDA HARUO
IPC: H03C1/00
Filed: 1997-09-05
Abstract: Since output voltage e of coupler CU2 is displaced in phase by -135 degrees from input signals c and d (by -270 degrees from signals a and b), a carrier which makes signal f is phase shifted by -270 degrees by phase shifter ~1 so that signal f may have the same phase as signal e. Signal f and signal e are power composed by first 3 dB coupler M1, and are further phase shift controlled by variable phase shifters PH11 and PH12 so that they may have the same phase.      Further, an output signal of variable phase shifter PH11 is phase shifted by -90 degrees by phase shifter SH1 so that it has a phase difference by 90 degrees from an output signal of variable phase shifter PH2, and the two signals controlled in this manner are inputted to 3 dB coupler M2. Consequently, two signals e and f inputted to the amplifier are all outputted as output voltage EOUT. According to the present invention of a television broadcasting machine, since a carrier is phase modulated and amplitude modulated with amplitude information and phase information obtained from an input video signal, a vestigial side band signal is outputted to form a television signal without using vestigial side band.

Abstract: The present invention relates to an optical fiber ribbon.  The optical fiber ribbon includes a plurality of coated, substantially coplanar optical fibers and a ribbon matrix material which maintains the plurality of coated optical fibers in substantially coplanar alignment.  Each of the optical fibers includes a glass core, a cladding layer surrounding and adjacent to the glass core, and a primary polymeric coating material, preferably containing a silicone, surrounding and adjacent to the cladding layer.  The primary polymeric coating material adheres to the cladding layer to form a cladding layer-primary polymeric coating material interface.  Upon application of a longitudinal stripping force at the cladding layer-primary polymeric coating material interface, the ribbon matrix material and the primary polymeric coating material are substantially removed from the cladding layer.  A continuous, smooth residual layer of the primary polymeric coating material with a thickness of less than about 5 µm remains on the cladding layer.  These optical fiber ribbons exhibit enhanced strippability without sacrificing adhesion of the primary coating material and are well-suited to being spliced by mass fusion splicing techniques.
