Title: Fluorescent cell ion concn. measurement - uses light sources directed at test section through diffraction grid and focus system
Inventor: UHL RAINER DR
IPC: G01N21/64
Filed: 1991-05-10
Abstract: The fluorescent measurement system, to determine concns. of ions, has two illuminating units (1,3;2,4) where at least one is pulsed. A diffraction grid (6) is illuminated by both units so that their rays are combined at the level (7) of the outlet gap to emerge with a bichromatic intensity profile of different wavelengths from the direct light sources. The structured light is focused (8,10,11) on the test piece (12) which has been coloured with a fluorescent dye. The excitation varies according to the ion concn.. A detector (14) converts the fluorescent light into a measurement signal. USE/ADVANTAGE - Cellular characteristics and intercellular processes can be observed, such as in the study of complex nerve and brain structures, without the need for intact cell structures obtained by vivisection. The fluorescent application reduces observation times.

Title: Speciality yarn production - has attachments to the rotor spinning machinery
Inventor: EDBERG BENGT PROF
IPC: D01H4/34
Filed: 1991-07-24
Abstract: A process to mfr. effect yarn on an open-end spinning machine, which has a fibre flow from the opening roller to the spinning zone along a channel is claimed. The flow of fibre is intermittently altered by means of pressure applied into the fibreflow channel. Pref. the opening roller (A) separates the fibre supply (L) into separate fibres (F), which flow in the channel (P), to the yarn production (M). The fibre is assembled into yarn by centrifugal force in the rotor groove (W) and drawn out as yarn (Y) through the roller pair (Z). An air current drawn from the chamber (I) ensures a continuous flow of fibre. By means of an intermittent barrier, the yarn develops thick and thin places, or slubs, to form effect yarn, with variable regularity. ADVANTAGE - The effect yarn is produced without causing breaks in the yarn. Normal smooth yarn can be produced on the same machine. The style of yarn can be varied.

Patent DE-4136462-A1 (DE)
IPC: G01N27/447
Filed: 1991-11-01
Abstract: A process is disclosed for separating enantiomers by an electrokinetic process in capillary columns, using surface-immobilized chiral components. The chiral component used may be a polysiloxane to which alkylated cyclodextrine ( alpha ,  beta or  gamma ) has been chemically bonded and which is immobilized on the surfaces located in the separation system, for example. This process is useful for qualitatively and quantitatively analyzing isomers, in particular enantiomers. In particular, it is not limited to non-decomposed volatile analytes, as in gas chromatography. A typical advantage of this process, besides its high resolution, is the long service life of the arrangement used. When it is used in addition to mobile phases, the separation components must be made available again after each analysis operation.

Title: Aircraft, in particular a wide-body aircraft
Inventor: SCHLIWA RALF
IPC: B64C25/32
Filed: 1993-04-26
Abstract: The invention relates to an aircraft, in particular a wide-body aircraft, having at least two decks which are arranged one above the other and in which passenger cabin areas and/or service facilities are arranged in at least that deck whose floor is the closest to the fuselage lower skin. It is a requirement to enlarge the utilisation potential of a lower deck in an aircraft, in particular a wide-body aircraft, in such a manner that passenger cabin areas as well as service facilities can be used even during the take-off and landing phases, while sufficient survival space is contained for the passengers in the event of crash landings or emergency landings. This object is achieved in the case of an aircraft of the generic type in that at least one energy-absorbing structural unit (5) is arranged in the region of the fuselage lower skin (7). It is particularly advantageous that the impact energy which is produced in a crash is absorbed in a controlled manner and that the survival probability of the people involved is thus considerably improved, since the necessary survival space is maintained. <IMAGE>

Title: Method of removing residual concrete from hopper and delivery pipe of piston type pump - involves running pump empty to create air pressure expelling part of residual concrete and then pumping water behind sponge to expel remainder
Inventor: TAKEZAKI TOSHIO
IPC: B08B9/04
Filed: 1993-07-15
Abstract: After the feeding of concrete, the pump is driven empty to produce a pneumatic pressure that expels part of the residual concrete from the end of the delivery pipe (3). A sponge plug (11) is then introduced into the delivery pipe via the hopper (1) and pump cylinder (12) and the hopper filled with water. The pump is again actuated until the remaining residual concrete has been expelled by hydraulic pressure. After residual concrete has been expelled the pump is reversed to return the cement laden water to the hopper, where it can be pumped to drainage or a cement mixer. ADVANTAGE - Operator's task is simplified. Contamination of ground is avoided.  Raw material wastage is reduced.

Inventor: SCHNEIDER FALK WALTER
IPC: B05C17/005
Filed: 1993-10-04
Abstract: The sealing of cartridges, in which a liquid is stored and from which the liquid can be conveyed in each case by means of a piston which is axially movable in the cartridge, is all the more problematic, the more highly viscous said liquid is because considerable internal pressures then occur during delivery. By means of pressure pieces (3) which are appropriately provided on the piston and are charged with the compression force (F) providing the delivery, the invention ensures that the pressing-on force of the piston against the wall of the cartridge increases with an increasing internal pressure. <IMAGE>
