Title: Process for the determination of a protein according to the principle of fluorescense polarisation immunoassay
IPC: G01N33/542
Filed: 1989-02-28
Abstract: To determine a protein in a homogeneous system, a sample solution is incubated simultaneously with
 a) a peptide sequence which is labelled with a fluorescent compound and is composed of 6 to 14 amino acids, of which two are cysteine, which together form a disulphide bridge, the sequence corresponding to an epitope sequence of the protein to be determined and
 b) an antibody which is able specifically to bind both to the protein and to the peptide sequence and has molar relative affinities for the fluorescent peptide sequence of the protein and for the native protein which differ by not more than a factor of 6, and the depolarisation of the polarised light passed through the incubated solution is measured.

Title: Scaffolding platform
IPC: E04G1/15
Filed: 1990-12-18
Abstract: In the respective common contact face (4, 5) of the multilayered scaffolding platform (1, 2, 3), two fabric strips (7A, 7B; 8A, 8B), which extend along the contact faces (4, 5), are inserted. The strip is inserted loosely. If an object now falls onto the scaffolding platform, the wooden layers are broken by the impact energy. Consequently, part of the striking energy is destroyed. The residual energy can now be absorbed by the strips which are then only subjected to a tensile stress caused by a much smaller energy. The platform parts broken away from one another are thus still held together, so that an object falling onto the scaffolding platform and breaking the wood cannot fall down any further. <IMAGE>

Title: Optical communication system
IPC: H04B10/293
Filed: 1990-01-25
Abstract: Disclosed is an optical communication system in 
which a digital data bus constituted by optical fiber is 
used as a transmission line. Each terminal equipment (A, 
B, ..., D) measures an optical output level to enable the 
terminal equipment to receive a packet transmitted from 
the terminal equipment per se and informs other terminal 
equipments of the measured optical output level. Each 
terminal equipment establishes its optical output level to 
be the largest one of the levels informed thereto. 
Further, each terminal equipment measures the delay time 
of an acknowledge bit transmitted from the other terminal 
equipments to thereby shift the sampling point by the mean 
value of the measured delay time, so that bus connection 
of terminal equipments through optical fiber can be 
facilitated, channel access control based on CSMA/CD can 
be performed, and wiring between the terminal equipments 
can be saved by performing multiple transmission of audio 
signals and video signals as well as digital data.

Title: An atomizing nozzle device and an inhaler
IPC: B05B12/06
Filed: 1990-03-07
Abstract: An atomizing nozzle device (10) comprises a housing (12), in which an 
inner chamber (32) is defined. Fluid is introduced into the chamber 
(32) and is discharged therefrom through an orifice (26) of a 
metallic screw cap (24) of the device. Within the chamber (32) a stem 
(34) is arranged, which stem (34) is connected to a closing head (44) 
cooperating with the orifice (26) through a rod (42). A spring (40) 
acts on the stem (34) for causing the head (44) to close the orifice 
(26) and consequently prevent the discharge of fluid from the device 
(10). A solenoid coil (46) is provided and supplied with a current 
through a current path in which a switch contact is established 
through the cooperating closing head (44) and the end cap (24). By 
the supply of an energizing current to the solenoid coil (46), the 
stem (34) is caused to move causing the closing head (44) to move 
relative to the orifice (26) for opening the orifice and consequently 
discharging fluid from the nozzle device. By the movement of the 
closing head (44) relative to the cap (24), the current supply to the 
solenoid coil is interrupted resulting in that the spring (40) forces 
the closing head (44) to close the orifice (26). Through the 
establishment and interruption of the current path to the solenoid 
coil, a self-controlled vibrating-type nozzle device is provided.
