Title: Effect luminaire (decorative luminaire)
Inventor: MORZYNSKI JOERG
IPC: F21V11/14
Filed: 1988-07-28
Abstract: A device for producing real and virtual (unreal) spaces which are bounded by grid surfaces, interference patterns, so-called moiré shapes, being created when the luminaire is looked at. This object is achieved according to the invention by forming a space which is illuminated by at least one light source, is bounded by at least one transparent wall surface (1) which can be structured like a moiré, and at least one mirror (3, 4). When the viewer looks from outside through the transparent regions of the grid surface (1) into the space he looks onto the side of a grid surface (1, 2) facing the inner space or he sees its image in one of the mirrors (3, 4), either through simple reflection or through multiple reflection on a plurality of mirrors whose reflecting sides always face the inner space. The viewer thus obtains the impression as if the space were bounded only by grid surfaces (1, 2). Grids (1, 2) and mirrors (3, 4) can be arranged on a support (6) by means of fastening means (10, 11, 12, 13). The invention is used as effect luminaire. <IMAGE>

Patent DE-3916774-A1 (DE)
Inventor: HEGGENSTALLER ANTON
IPC: B27M3/14
Filed: 1989-05-23
Abstract: The invention relates to methods and devices for the manufacture of girderlike shaped bodies (15) from vegetable particles mixed with binders, in moulding presses. Starting from the knowledge that the core of such shaped bodies (15) is compressed less, the greater the cross-section of the shaped body (15), the invention proposes to form the core region of the shaped body (15) from a particle additional mass which is specifically moved thereto and compressed and which, on compression of the shaped body (15) by cheek plates (2 to 5) surrounding it, acts reactively as a crushing zone (28). In this way, a continuous compression of the shaped body even of large cross- section is achieved, and at the same time a particularly powerful compression of the peripheral regions of the shaped body. The strength and flexural rigidity of such shaped bodies (15) is particularly great, making them suitable even for forming railway sleepers.

Title: Flat-bed knitter - gives firm ends to linked fabric sections developed in succession
Inventor: ESSIG HORST
IPC: D04B1/06
Filed: 1989-11-30
Abstract: To give a constant flow of garment sections from a flatbed knitter, each linked together, at least one row of stitches is executed at the end of the knitted section, using only a part of the needles of at least one needle bed, separated from each other by other needles. This is formed by a row of stitches with a separating yarn developed by unused needles.  Through repeated changes of the needle beds, the stitches are suspended and a firm fabric closure is knitted from one side edge of the knitted material. When the separating yarn row is formed, the sepg yarn is worked into catch loops by the free needles of only one needle bed.  To form the firm fabric closure end, initially a needle bed is displaced by at least one needle interval and an  edge stitch is formed by the displaced needle bed. ADVANTAGE - The technique gives a firm edge to each of the fabric sections.
Patent DE-3941547-A1 (DE)
Inventor: TANI NOBUHIRO
IPC: H04N5/235
Filed: 1989-12-15
Abstract: In an image CCD sensor to which are supplied periodic transfer pulses CTG for transferring signal charges accumulated in its light receiving portion to vertical transfer CCD portions, read pulses  phi V1 -  phi V4 to read the charges in the vertical transfer portions, and sweep pulses for rapidly discharging to a drain unwanted charges in the vertical transfer portions, a controller for controlling all these pulses also permits the supply of an additional transfer pulse PTG at a selected time whereby the effective exposure period TV of the light receiving portion may be varied relative to the period of the pulse CTG. Following PTG and before the desired signals are transferred by the next CTG pulse, unwanted signals in the transfer portions are swept to drain. A diaphragm may be controlled so that reading of the desired signals occurs when it is closed. Yet further additional transfer and sweep pulses may precede the desired exposure (Fig 13) to increase the efficiency of the main sweep pulse. Reference is made to still and movie modes. <IMAGE>
