Title: Covering such as a suit, glove, condom or sheath forming a chemical barrier against harmfurl agents and methods of making the same
Inventor: SHLENKER ROBIN R T
IPC: A41D31/00
Filed: 1991-02-21
Abstract: Abstract of the Invention A covering such as a suit, glove, condom or sheath forming a chemical barrier against harmful agents.  The covering is flexible, stretchable,  and  relatively thin,  and  includes  at  least  one relatively thin chemical barrier that will neutralize the harmful characteristics of the harmful agents.  If an object cuts through the covering and into a person's skin or if a harmful agent tries to traverse  through  the  covering,  the  chemical  barrier will neutralize the harmful characteristics of the harmful agent so that the agent is neutralized either before reaching the person's skin, after reaching the person's skin, or both.   Various methods of making the covering are also disclosed.

Inventor: DECHER GERO
IPC: B05D1/18
Filed: 1991-08-22
Abstract: One- or multi-layered layer elements applied to supports and their production Abstract One- or multi-layered layer elements applied to supports are described, which consist of a)   a modified support having an even surface, in which modification  means  the  application  of  ions  or ionisable compounds of the same charge over the entire area, and b)   one or more layers made of organic materials which in each layer contain ions of the same charge, the ions of the first layer having the opposite charge of the modified support and in the case of several layers each further layer having again the opposite charge of the previous layer.            Layer elements of this type applied to supports are produced by applying the individual layers from solutions of the organic materials in suitable solvents to modified supports by sequential physisorption (salt formation).

Title: Optical beam steering device
Inventor: SCOTT ANDREW M
IPC: H01S3/101
Filed: 1990-04-11
Abstract: An optical beam steering device (10) incorporates a laser (12), three Brillouin shifters (22 to 26, 44 to 48, 54 to 58), a four wave mixing cell (40) and a low power beam steering device (62).  The first shifter (22 to 26) and the mixing cell (40) contain TiCl 4, and the other shifters (44 to 48, 54 to 58) contain 20 %  CCl4/80 % CS2. The first and third shifters (22 to 26, 54 to 58) frequency downshift the laser beam (16) by .delta.)A and .delta.)B respectively. Light (16') from the first shifter (22 to 26) is amplified and provides a first pump beam input to the mixing cell (40). It then passes to the second shifter (44 to 48), for frequency downshifting by .delta.)B and returns as a second cell pump beam (16''). Light (18') from the third shifter (54 to 58) passes via the low power beam steering device (62) to the cell (40) as a weak input signal beam (18''). The cell (40) responds to the pump beams (16', 16'') and signal beam (18'') by generating a high power beam (68) which is a phase conjugate of the signal beam (18'') and retraces part of its steered path.

Title: Method and apparatus for controlling the cutting and placement of components on a moving substrate, and article made therewith
Inventor: UNGPIYAKUL TANAKON
IPC: B26D5/34
Filed: 1992-07-03
Abstract: A distinctive apparatus and method for selectively providing predetermined segments of web material comprises a supplying mechanism for providing the web material. A first sensing mechanism detects a reference marker on the web material to generate at least one reference marker datum which is associated with a selected web segment. A separating mechanism includes a sensor mechanism for providing at least one separation datum, and divides the web material along a separation region during a production of the web segment. A phase regulating mechanism controls a relative phasing between the reference marker detected by the first sensing mechanism and the dividing by the separating mechanism. The phasing is conducted with respect to a set reference value. An assembling mechanism places the web segment onto a substrate, and a second sensing mechanism separately detects a location of the separation region relative to the reference marker to generate at least one location datum which is in correspondence with the separation datum. A location correlating mechanism generates at least one comparison datum associated with a web segment, and a data processing mechanism evaluates the comparison datum to generate an updated set reference value. A reference regulating mechanism selectively adjusts the phase regulating mechanism to incorporate the updated set reference value.
Patent CA-2073176-A1 (CA)
Title: Lining of pipelines or passageways
Inventor: SMITH EDWARD P
IPC: F16L55/16
Filed: 1991-01-16
Abstract: The method provides that a pipeline (10) or passageway (10) wall is coated using a backstop means, a body of resinous material (6) and an everting tube (5). These items are located inside the passageway to be lined and moved there along with the backstop (1) providing support for the bulk of resin material and also applying pressure via the resin material onto the everting face (16).  When the everting tube is a resin absorbent material, the presence of the bulk of the fluent material prevents air from becoming entrained in the everting face and prevents voids in final lining.  The resin may be introduced via a tee piece (12) through the lag thereof whilst the everting tube is introduced along the arms of the tee.

Title: Treatment of periodontitis
Inventor: VAN DER OUDERAA FRANCISCUS J G
IPC: A61P1/02
Filed: 1992-08-07
Abstract: The present invention relates to the prevention of periodontitis by the use of a medicament which contains Triclosan. It has been found that Triclosan has a considerable anti-cyclo-oxygenase activity, thus inhibiting the formation of prostaglandins which are mediators of the loss of alveolar bone in the periodontium.  Reducing the formation of said prostaglandins therefore reduces said loss of alveolar bone, which is one of the symptoms connected with periodontitis.            The medicament is preferably in the form of a toothpaste.
