Patent DE-19716115-A1 (DE)
Title: Toner particle control in direct printing process
Inventor: KLOCKAR PER
IPC: B41J2/415
Filed: 1997-04-17
Abstract: A direct printing process in which loaded particles are deposited successively onto the paper or other medium uses a toner central system consisting of two complementary sets of electrodes positioned between the toner drum and the paper. The system comprise an insulated substrate (7) with multiple holes (10), each surrounded by a ring electrode (11) and arranged in parallel series (12), running across the width of the printing area and vertically to the movement (4) of the medium. Two sections carrying the same number of electrodes are positioned on either side of a central cross axis (13). Each electrode has a separate connection (9) to its control source (8). By operating the sections in periodic sequence, interaction between electrostatic fields is prevented and the quality of the picture is improved.

Patent DE-19724140-A1 (DE)
Inventor: JAKOB GERD DIPL ING
IPC: H04N7/18
Filed: 1997-06-07
Abstract: The invention relates to electronic spectacles, especially night vision spectacles, comprising a spectacles part (1) which is connected by a cable (3) to a pocket part (2). At least one electronic camera, e.g., a CCD camera, (5), and at least one display (8) for viewing by the user are provided on the spectacles part (1). A battery (9) and all or part of the electronic image processing system (20) required for operating the device are located in the pocket part (2). Said electronic image processing system (20) also provides automatic contrast optimisation which is carried out automatically as light conditions change. In order to perform this function, the electronic image processing system (20) comprises an analysis circuit (21) which determines the grey value distribution (H(x)) in the image recorded by the electronic camera (5). This information is conveyed to a transformation circuit (22) which produces a modified grey value distribution H'(x)) from the original grey value distribution (H(x)) in accordance with a transformation formula ("equalisation curve"). Whilst the number and frequency of discreet grey values which appear remain the same, the location of said grey values is modified in such a way that overall there is a greater range of grey values.

Title: Sandwich plate with profile core for fibre composite structures
Inventor: UNCKENBOLD WILM FELIX DR
IPC: B61D17/04
Filed: 1997-06-30
Abstract: The thrust ribs (20) have a double-curve S-shape. The thrust ribs in the area of the cover layers (2,3) are formed to them vertically. Individual, independently formed profile modules (11) of the profile core (10) are arranged next to and on each other. In the area of the connection of the thrust ribs (20) to the cover layers (2,3), hollow spaces (30) between the adjacent cover layers and modules remain, which are filled with fibres, particularly uni-directional fibres. The fibre volume extent of the hollow spaces (30) is as low as possible, almost at nil level. The spring rigidity of the profile core (10) of the sandwich plate (1) is alterable and adjustable through the choice of the height of the profile core and the angle of the doubly curved S-shape of the thrust rib (20) within the profile core.

Title: Extraction of standard sample of sediment from stream bed
Inventor: GEIST JUERGEN
IPC: G01N1/08
Filed: 1997-12-09
Abstract: Taking a sample of sediment from the bed of a stream comprises inserting a plastic tube into the stream bed and lifting by use of a builder's trowel. Taking a sample of sediment from the bed of a stream comprises marking an open-ended plastic cylinder with a strengthened metal rim at a predetermined point with a collar piece of insulating tape. The strengthened metal rim is then pushed into the bed of the stream up to the collar, and the open upper end is closed with a bung. From the downstream position, a bricklayer's trowel is pushed at an angle under the base of the cylinder, the handle being levered downwards to raise and lift the cylinder clear of the water. The cylinder and contents are then positioned over a receptacle such as a bucket, and the sedimentary contents are released and captured for later analysis.
