Inventor: WROGE HENNING VON DER
IPC: F16G3/10
Filed: 1989-12-18
Abstract: A splice for both ends of a steel cord conveyor belt has a steel cord insert embedded in an elastomeric material and consisting of parallel, longitudinal steel cords. At least some of the ends of the steel cords of the two ends of the belt are aligned in pairs with their front faces a longitudinal distance apart and are coupled to each other by means of longitudinal elastic elements which surround them. To ensure high transmission of tensile forces and a simple, rapid method of making the splice, each element consists of a tubular braiding (22) consisting of interlaced metallic and/or textile threads (25) and/or fibres. The space (21) between the front faces (23, 24), which is surrounded by the braiding (22), and the gaps between the stitches of the braiding (22) are filled with an elastomeric material.

Title: Transforming immature somatic plant, esp. maize, embryos - by treating, in dry state, with nucleic acid soln., esp. for introducing resistance to phosphinothricin
Inventor: DONN GUENTER DR
IPC: C12N15/54
Filed: 1990-04-25
Abstract: Immature somatic embryos are transformed by being incubated, in the dried state, with a soln. contg. DNA or RNA.  Also described are (1) transformed somatic embryos of monocotyledonous plants and (2) plants regenerated from these embryos.  Embryos are pref. derived from callus or organ cultures, partic. of Gramineae, specifically maize. Before incubation with the nucleic acid soln., the embryos are cultured in a nutrient medium contg. sugar or sugar alcohol. Embryos (which have at most 75% of the size of mature embryos) are pref. dried, to 5-15% moisture content, under gentle conditions over a 10-18 day period. They can then be stored at room temp. for over a year.  Rehydration is in a medium contg. 2-6% sucrose (and opt. agar), and the nucleic acid is supplied as an aq. soln., opt. also contg. medium components and buffer salts. Nucleic acid can express e.g. a selection marker (such a sPAT); Bacillus thuringiensis endotoxin; a protein for virus resistance; protein which improves photosynthetic capacity, etc.. Gene can be present or incorporated in a cloning vector, and the embryos can be treated with UV light or X-rays to break DNA strands. USE/ADVANTAGE - Dried, monocotyledonous somatic (opt. transgenic) embryos are useful in prodn. of 'artificial seeds', or they can be regenerated and grown to fertile transgenic plants.  Esp. maize plants are modified by incorporation of the phosphinothricin acetyl transferase (PAT) gene (opt. modified) from Streptomyces viridochromogenes. This imparts resistance to phosphinothricin (I) and bialaphos to the plants and their derivs..
Patent DE-4013404-A1 (DE)
Inventor: TANAKA NORIKO
IPC: H04N1/407
Filed: 1990-04-26
Abstract: An image reading apparatus in which automatic gain control is performed comprises a reading unit, integrated with an optical system having a light source (12) for irradiating an original, a rod lens array (13) for focusing an image, a line image sensor (11) for reading the image, and a white reference plate (17) attached on one end of reading unit so as to move together therewith. There is effect in that one and the same portion of the white reference plate is read by the line image sensor as it scans across a document so that gain control of the output of the line image sensor is based on a constant reference white. Further even if a part of the white reference plate becomes dirty, an even output can be obtained throughout the whole surface of the original to thereby make it possible to prevent deterioration, such as generation of transversal stripes, from occurring in the output picture. <IMAGE>
