Abstract: A radiation field analyzer (10) provides means for analyzing the spatial mode spectrum of radiation received from a scene. In a multimode waveguide embodiment, light from a laser (24) is directed towards a scene through an alumina waveguide structure (12). A portion of the laser light is directed towards a mode generator (28) which selectively converts the laser radiation into one of a series of modes. Laser light returning from the scene is mixed with the light from the mode generator to produce interference signals. These signals are measured by a detector (34) and analysed by a programmed computer (36). By sequentially altering the mode generated by the generator (28) and analyzing the resulting signals, a spectrum of the modes returning from the scene is obtained.

IPC: B65H29/02
Filed: 1998-08-14
Abstract: For monitoring the thickness of printed products (1) which are conveyed by one conveying means each in a continuous conveying stream with a conveying direction (F), monitoring elements (4) are introduced into the conveying stream and one monitoring element is allocated to each printed product. The monitoring elements (4) substantially consist of a pair of monitoring levers (10, 11) with clamping jaws (13) which are pressed against each other with a clamping force. For the monitoring, a region of each printed product (1) is clamped between the clamping jaws (13) of a pair of levers (10, 11) which are pressed against each other. Pairs of one monitoring element (4) and one printed product (1) interacting with each other by clamping are conveyed in succession through a monitoring area. For quantitative recording of this interaction, an image is recorded of one edge of each of the monitoring levers (10, 11) of one lever pair and of the distance (D) between these edges (30), which distance depends on the thickness of the pressed printed product (1). From this image a measured value corresponding to the distance (D) is determined. The measured value is compared with a reference range allocated to each monitoring element (4). The reference range is constituted by a reference value determined by calibration and a predetermined tolerance range, whereby a calibration is carried out for each control element (4) using a product with a known, i.e. correct thickness.

IPC: D04B21/06
Filed: 1998-11-12
Abstract: A Jacquard fabric includes a Jacquard yarn plaited into a base knit structure such as, for example, a "Sleeknit" structure. The fabric may be knitted on a warp knitting machine having at least four guide bars, the frontmost guide bar being a Jacquard guide bar, with the Jacquard yarn being knitted in a knit-float-knit sequence. The two middle guide bars are, for example, fully threaded with multifilament synthetic yarns (e.g. Nylon or polyester), which knit on alternate courses and float on alternate courses. The backmost bar may be fully threaded with, for example, an elastomeric fiber (e.g. Lycra Spandex) which may be laid into the structure during knitting. In an exemplary method for producing the fabric of the present invention, the two middle guide bars knit on alternate courses, so that only one of these bars is knitting on any one course. The arrangement allows the Jacquard  yarn to be plaited into the same course and stitch as the finer multifilament yarn on the odd-numbered courses, creating a softer fabric. In addition, the fabric may be produced without a dropping of the stitch from the needle, even when the Jacquard guide bar is being deflected.

Inventor: WHITSON ROBERT L
IPC: A01G9/28
Filed: 1999-08-11
Abstract: The present invention relates to a composite masonry edging or stepping block used with other like-shaped blocks to form a continuous interconnected edging pattern or stepping path that accommodates straight sections and tight bends in the pattern or path. Each block has a series of six adjoining projections around a major portion of its perimeter, and a pair of adjoining recesses along a minor portion of its perimeter. Two adjoining projections form a multi-wave protrusion. Several combinations of two adjoining projections can be used to form a number of multi-wave protrusion. Each protrusion has the same size and shape but extends in a different angular direction. The two recesses form a multi-wave indentation. The multi-wave indentation flushly receives one of the multi-wave protrusions of an adjacent block to achieve an interlocking connection in either straight or angled alignments. The structure of each block forms a flower-like pattern. Part of the pattern is formed on the upper surface of the block by several spaced, arcuate grooves that radially extend from near the middle of the block to its perimeter. Part of the pattern is formed by the projections that have arcuate sides and beveled edges that align to smoothly continue the arcs of the grooves. The grooves and projection combine to form a series of petaline shape. Several interconnected blocks produce a flower-chain appearance.
