Title: Metal-ion-free developer compsn. - contg. choline, tri:methyl-(hydroxy-ethoxyethyl)ammonium hydroxide, alkanol-amine and water, useful in developing of positive photoresists
Inventor: MENZ IRINA DR
IPC: G03F7/32
Filed: 1991-01-23
Abstract: Metal ion-free developer compsn. (I) for high-contrast developing of positive photoresists based on naphthoquinone-diazide/novana ween the casing (8) and the grid (4) surfaces (12A) (13) and (41A). Coolant leak flow across these surfaces causes a depression which forces the casing (8) toward the grid (4). A surface (12) is provided to supress oscillation of the fuel element casing (8). Pref. surfaces provided on each of the two opposite sides of the outer surface of the lower grid plate of the fuel element are placed for the resultant forces to be differently positioned. The forces produced are also different on each of any two opposite sides. A force is produced on all sides of the fuel element casing. Surface elements are provided on the outer surface of the grid which hinder any flow of coolant from outside the fuel element casing. An element on the downstream side of the coolant leakage channel hinders flow but does not reduce the depression produced forces. The depression is produced by a section of a venturi. The dimensions of the venturi are related to various dimensions of the lower grid plate (4). USE/ADVANTAGE - For fuel element casings for use in boiling water reactors. Tends to supress leakage flow between the fuel element casing and the lower fuel rod grid and prevent creep deformation of the casing. Oscillations and flutter cased by leak flow supression method are corrected for.

Title: Heat and sound insulating foamed plastic floor-to-wall edging strip - includes deformable insert pref. of low elasticity plastic, to hold strip close to wall corners, avoiding bulging and damage from floor screed
Inventor: BRUNING JUERGEN
IPC: E04F15/02
Filed: 1991-04-30
Abstract: Heat or sound insulating edging strips of foamed plastic, for use between building floor screed and walls, contg. a deformable insert (2), esp. of low elasticity plastic (not further specified). The insert may be in the form of a mesh or cords - the latter permits several adjacent profiles or rods. Alternatively to extrusion, the prepd. insert may be embedded in the strip during foaming or laid between two foam strips, which may then be welded by infra red or hot air heating and pressure. USE/ADVANTAGE - Insert, when bent, prevents significant recovery (straightening) of the strip and holds edging strip close to corners in walls, without bulging, avoiding penetration of the strip by the screed or inadequate levelling of the screed. Compared with known cross-slitting of the foam edging strip, which reduces the flex resistance of the strip so that it conforms to corners, the insert increases the flex resistance, to hold the strip in the bent position. The pref. plastics insert has the advantage over metal that it can be extruded simultaneously with the strip foaming process.

Pref. the electrical line (3) is provided by a metal coating pref. obtained by vapour deposition which has a small thickness relative to the dia. of the optical line (2), or by a metal mesh. A coaxial separation element (4) pref. lies between the optical line (2) and the electrical line (3), with the latter enclosed by an outer mantle (5).
Patent DE-4125899-A1 (DE)
Inventor: METLITSKY BORIS
IPC: G02B26/10
Filed: 1991-08-05
Abstract: A portable scanning head emits and receives light from a light-emitting diode (10) to read symbols, such as bar-code symbols. The optics (12,18) within the scanner are operative for focusing a light beam (11) and the view of a light sensor (17) in different planes (13,22) exteriorly of a scanner housing. Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED (10) as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode (17) "sees" only that portion of the scan spot visible through the viewing window.

Inventor: KLEFFMANN GERD
IPC: C10L9/10
Filed: 1991-12-06

Other possible disposal methods are direct solidification of the organic waste prod. or, its burning prior to storage. The former has a corresp. high storage vol. while the latter produces radioactive combustion gases. By chemical, exothermic redn. of the organic waste, a waste vol. one sixteenth of the original is obtd.

Inventor: HEITMANN UWE
IPC: A24B1/04
Filed: 1992-02-25
Abstract: The invention relates to a process and an arrangement for detecting relatively hard foreign objects, e.g. composed of stone or metal, which are located in a flow of piece-goods, in order to prevent the foreign objects from causing malfunctions in the processing of the goods. The foreign objects are detected by conveying or guiding the goods, together with the foreign objects contained in them, onto a surface which is connected to a sensor which emits a signal upon the occurrence of a vibration value characteristic of the foreign object.   Malfunctions can be prevented by displaying that a foreign object is located in the goods or by automatically discharging foreign objects.   <IMAGE>

Title: Compensation of vertical or horizontal underground movements - using mineral pastes, which are pressed into ground and disintegrate into ground-preserving minerals
Inventor: GUDEHUS GERD PROF DR ING
IPC: E02D3/12
Filed: 1992-03-28
Abstract: Viscous mineral pastes (4) are pressed into the ground. After a period of time, the pastes disintegrate into ground-preserving minerals. The solids contents of the paste consist of granular substances, which do not undergo chemical changes, and are compatible with the ground. After mixing, the fluid components convert biochemically into a highly viscous fluid. After pressing into the ground, this reverts to be as liquid as water, without the creation of ground-damaging substances. The components may be mixed acc. to any desired method, and there is an addition of air bubbles, which is optimum for pressing-in. The pastes are introduced via flexible tubes or hoses, via valves or packers. USE/ADVANTAGE  - Introduced materials adapt to natural ground functions, and have no disadvantageous effects
