Title: Plastics material mesh structure
Inventor: MERCER FRANK BRIAN
IPC: B29D99/00
Filed: 1982-10-04
Granted: 1986-07-17
Abstract: In order to provide uniaxially-stretched and biaxially-stretched mesh structures which allow for different specific designs of the interconnecting strands, a special punching pattern is used to provide holes 2, 3 in the starting material 1. The starting material 1 has a "square" pattern of large holes 2. Further holes are added. These further holes can be small holes 3 which are staggered and in pairs. When the starting material is stretched, the uniaxially-stretched structure has transverse bars 9 interconnected by highly orientated strands 6 each of which forks at both ends into further highly orientated strands 8, providing a structure which is particularly suitable for soil reinforcement. When the structure is stretched in the direction at right angles to form a biaxially-stretched structure, the zones of the bars 9 which are between aligned strands 8 remain as unorientated or partly orientated junctions 19. The remaining zones of the bars 9 are stretched out to form highly orientated strands 15, 17. This biaxially-stretched structure is particularly suitable for soil stabilization.

Patent DE-3482143-D1 (DE)
Inventor: EASTMAN JAY M
IPC: G06K7/00
Filed: 1984-08-17
Granted: 1990-06-07
Abstract: An optical device for detecting bar codes (markings or patterns which symbolize data such as the name and vendor of a product) are detected by an optical device which serves as a bar code scanner. A laser diode and associated optics provides an invisible beam. A visible marker beam coincident with the laser beam is generated by a lamp and associated optics and directed coaxial with the laser beam so as to enable the laser beam to be scanned across the bar code by moving a housing in which the laser and the lamp and their associated optics are disposed. Also contained in the housing is a photodetector on which scattered light from the code is incident after passing through a collection lens located at an outlet port for the beams. An aperture is positioned between the collection lens and the detector. The location and size of the aperture and the focal length of the lens are related such that the illumination by the reflected light of the detector is substantially constant and the output signal from the detector which represents the bar code is also constant amplitude over a wide depth of focus in front of the beam port. Unwanted reflections (gloss over the bar code) are rejected by selecting the polarization of the reflections opposite to the polarization of the laser beam, as by the use of a polarizing beam splitter. A spectral beam splitter is used near the detector to select the scattered laser light for the photodetector which generates electrical signals corresponding to the bar code.
