Title: Threaded anchor for poured concrete metal deck floors and wood frame floors
Inventor: WATKINS KEITH L
IPC: E04B1/41
Filed: 2000-11-21
Abstract: An internally threaded insert anchor (41) for use in poured concrete floors having metal decking or wood form is described which provides setal deck or wood form, prior to the concrete being poured. Once locked into the con-crete floor (61), the threaded insert anchor (41) provides easy attachment for the support rods that carry the racks of utility, piping and ceiling grid systems for the building.

Title: Optical duobinary single sideband modulator
Inventor: DAVIES ROBERT J
IPC: H04B10/18
Filed: 2003-01-08
Abstract: An apparatus for modulating information bearing symbols onto an optical carrier includes a polybinary coder that operates on a binary information signal to produce an envelope compatible polybinary signal; and an optical single sideband modulator that modulates an optical carrier with the envelope compatible polybinary signal to produce a single sideband optical signal. This provides an improvement over both polybinary signaling and optical single sideband. This action combines the chromatic dispersion advantages of SSB modulation with the DC level and bandwidth reduction of duo-binary coding.

Title: Pull-tight one-piece security seal, adapted for the closure of bags or the like
Inventor: DE LIMA CASTRO ANDRE
IPC: G09F3/03
Filed: 2001-09-21
Abstract: A one-piece pull-tight or strap-type security seal adapted for closing bags or the like that is designed to be easily applied in comparison with existing ones. One seal of this type has a lever operation in which a closure strap (4) is integral with a central or operating portion (2) that is, its turn, integral with a lever member (6) to which the strap may be fixed during application around the neck of a bag to be closed. The lever member is then pivoted outwardly and backwardly over the operating portion, tightening the loop so formed by means of a lever action, and then locked by security locking formations (16, 19) to effect sealing. According to the invention, the closure strap is for all effects flat, its formations for fixing it to the lever member (6) comprising a series of orifices (7) distributed along its length, whereas the immobilising formation for the closure strap comprises a first protuberance (15) adapted, on formation of the loop (25), to be received in one of the said orifices (7). The operating member (2) may be provided with an elastic hook (24) that, in the closed position of the seal, passes through another of the orifices (7) in the closure strap so as to maintain the seal closed even if the locking formations are damaged or broken. A separate seal (26) is also described, in one embodiment, so as to permit uses of the one-piece seal (1) after the first use when the security locking formations 816, 19) have already been damaged or broken.
