Title: Concrete reinforcing system
Inventor: MATIISEN REIN
IPC: E04C5/16
Filed: 1995-01-17
Abstract: Currently available reinforcing devices for existing concrete structures include flat metal plates or similar smooth, rolled elements which are attached to the structures by an epoxy or glue.  Bolts or inserts are used to attach the plates directly to the concrete to act in conjunction with the epoxy or glue.  Such devices have several drawbacks, limiting the situations in which they can be used and increasing costs of installation. The drawbacks can be overcome by a simple reinforcing system for a concrete member including plates for mounting on opposite sides of a concrete member, an elongated bolt for extending through the concrete member and each of the plates, and reinforcing bars for mounting between one plate and the concrete member, the standard reinforcing bars extending between adjacent similar plates on such one side of the concrete member for reinforcing the latter. The system can include a variety of embodiments, including arcuate plates for increasing the hold on the reinforcing bars, new concrete reinforcing slabs for covering at least one of the plates, teeth on the plates for engaging the old concrete member and grout filled boxes for retaining bars against the concrete member.

Inventor: HAWES JOHN M
IPC: D21F1/00
Filed: 1995-02-20
Abstract: A triple-layer papermaking fabric  includes top and a bottom weft yarn layers interwoven with a system of warp yarns.  The warp yarn system includes pairs of associated, stacked first and second warp yarns.  The first warp yarn in each pair interweaves with the top weft  yarns  in  a  plain-weave  pattern  occasionally broken by an interweaving with a bottom weft yarn to join the top and bottom weft yarn layers together. The second warp yarn in each pair, ordinarily running between  the  top  and  bottom  weft  yarn  layers  and stacked below the first warp yarn, weaves over the top weft yarn  skipped by the first warp yarn when  it weaves down under a bottom weft yarn to maintain the plain-weave  character  of  the  top  surface  of  the fabric.   The second warp yarn never weaves with the bottom weft yarns.   The  fabric  is  flat-woven,  and subsequently seamed into endless form.  The first warp yarns have an exaggerated crimp to provide the fabric with  an  enhanced  seam  strength.    The  second warp yarns,  having relatively  little crimp,  provide  the fabric with an enhanced stretch resistance.

Title: Method for enhancing detail in color signals and circuitry for implementing that method in color video equipment
Inventor: LEE HYO-SEUNG
IPC: H04N5/208
Filed: 1995-02-24
Abstract: In video signal processing circuitry detail enhancement is done on each of three color channels (R, G & B) in response to the detail information, the enhancement of the detail in each color channel being done in reliance on separated high-spatial-frequency information originally contained in that channel, as long as it is sufficiently greater in amplitude than a reference level somewhat above that expected for thermal noise. When the amplitude of the detail information originally contained in a channel is insufficiently above that reference level, the thermal noise is suppressed by subtracting the separated high-spatial-frequency information therefrom. The same filter arrangements are used to separate high-spatial-frequency information for suppressing thermal noise in each color channel as for enhancing the detail in each color channel.
