Patent DE-4022956-A1 (DE)
Title: Simply positioned endo-luminal body - consists of thermoplastic-coated resistance wire with terminals, formed into cage-like structure, and placed over inflatable balloon
Inventor: FREUDENBERG SEBASTIAN DR
IPC: A61F2/90
Filed: 1990-07-19
Abstract: An endoluminal bar consists of insulated wire made into a cage-like structure which surrounds an inflatable balloon, leaving spaces round the circumference. These spaces are formed into a network by a regular pattern of welds in the surrounding insulation; this network can stretch circumferentially; the surrounding material can be softened thermally at least once so as to permit expansion by applying a voltage across the wire. Pref. forms of the insulation are polyethylene, polycaprolactone, copolyester, ethylene-vinyl acetate, PVC or thermoplastic polyurethane.

Title: Appts. for absorbing wave motions - uses friction and deflection to remove sufficient energy
Inventor: CLAUSS GUENTHER DR ING
IPC: E02B3/06
Filed: 1990-08-29
Abstract: This system for absorbing wave motions uses friction and deflection to take away sufficient energy from a wave encountered, to ensure that there is no breaking, reflection or build-up of waves. The system opt. includes a module for absorbing wave energy so that wave-subdued areas of the water surface are produced, and absorber plates with a mechanism for producing motion of the plates, relative to one another, so that the energy absorption effect is not impaired by highly viscous or other matter. USE/ADVANTAGE - The system overcomes the detrimental effects of waves on the efficient use of equipment for clearing the surface of the sea or other waters, and is of partic. use in clearing oil, an operation for which the water surface should be as free from waves as possible.

Title: Oil and gasoline separator providing mobile sepn. system - in which vessel contg. three chambers uses floating skimmer to remove oil from the surface of contaminated water
Inventor: WARTENWEILER HEINZ
IPC: B01D17/02
Filed: 1990-10-18
Abstract: A new oil/water separator consists of a vessel (3) with a floor (5) and four walls (7-13), which is divided into three chambers (19,41,35). Between the first (19) and second (41) chambers is a partition (15) which has at least one opening (17) near the floor (5), and between the second (41) and third (35) chambers is a second partition (23) in which a filter element (31) is fitted. A skimmer (43) is provided in the second chamber (41) and can move vertically on the surface of the water. The second partition (23) may be made up of two essentially parallel overlapping plates (25,27), in which case the filter element (31) occupies the space between their central overlapping portions. This filter element is contained in a cage (33) in which it is installed in the above space. The skimmer (43) may be attached to a vertical guide or may float freely on the surface of the water. USE/ADVANTAGE - This method is used for sepg. oil or gasoline from water by means of a disc-skimmer in industrial applications, in sewage works, on construction sites or at the scenes of accidents. Existing oil separators require the oil to be pumped out and taken away on a periodic basis, and a considerable quantity of water is unavoidably removed with the oil at these times. This invention allows the oil to be sepd. in an economical manner and without this disadvantage, and the sepd. oil can be taken away in drums by any suitable transport.

Title: Determining reverse transcriptase for diagnosing HIV etc. - using hapten-labelled or substd. nucleotide tri:phosphate in solid phase immunoassay, avoiding use of radio-labelled nucleotide
Inventor: PORSTMANN THOMAS PROF DR
IPC: G01N33/569
Filed: 1991-03-20
Abstract: Process for determining the activity of reverse transcriptase (RT) comprises using a hapten-labelled or substd nucleotide  triphosphate (I) and specific antibodies or other specific binding agents for (I). (I) is polymerised into a chain, and the degree of incorporation of (I) is measured in a binding test. Pref. the process is carried out in a double-sided assay, using identical antibodies as the solid phase antibody and as the labelled antibody for the chain. Part of the chain formed is therefore bound to the solid phase and the rest is determined by immunoassay. The labelled antibody that is not incorporated in the chain is separated through substrate optimisation by reaction of the RT excess or is measured in a double-sided, two part assay, so that the chain is not bound to the solid phase by the labelled antibody. The measurement is made after a washing process. A test kit comprises (a) a solid phase with immobilised anti-HIV 1-RT antibodies; (b) a solid phase as in (a) with insolubilised antibodies for binding a single or double chain; (c) labelled antibodies to the haptenised nucleotide; (d) RT-buffer concentrate with the corresp. haptenised nucleotide; (e) a substrate mixt. for the enzyme reaction; (f) a stop reagent for the enzyme reaction; (g) diluents; (h) washing buffer; and (i) control material (NaOH and citrate-phosphate buffer for single strand prodn.) USE/ADVANTAGE- For determining RT activity of HIV-1 and other retroviral infections. The process avoids the use of radiolabelled markers and so does not require specialised equipment. The process can be automated and can therefore be used widely and -easily.

Title: Process to transfer granular adsorbent - from adsorption zone to regeneration zone and to return adsorbent to adsorption zone
Inventor: CORNEL PETER DR
IPC: B01J20/34
Filed: 1991-05-15
Abstract: In a process to transfer a granular adsorbent from an adsorption zone to a regeneration zone, the adsorbent comes into contact with sulphurous smoke to be cleaned in the adsorbent zone and subsequently surrenders its load to a gas in the regeneration zone. The novelty is that the adsorbent leaves the adsorption zone and is first passed through a gas lock zone before advancing to the regeneration zone. The gas lock zone incorporates at least one gas lock which is filled and emptied in cycles through inlets and outlets controlled by valves. The smoke is admitted to the gas lock in a cycle; that the gas lock is at least partially filled with adsorbent. The smoke is drawn off from the gas lock. Regenerative gas is admitted to the gas lock so that the adsorbent is taken from the gas lock to the regeneration zone, and the regenerative gas is drawn off from the gas lock. USE/ADVANTAGE - The arangement facilitates the construction of a continual process for the use and regeneration of adsorbent.
