Title: Process and device for producing dental prostheses or prosthesis parts from polymerisable plastic
Inventor: HEYNOLD WOLFGANG
IPC: A61C13/14
Filed: 1984-11-03
Granted: 1986-03-20
Abstract: The process is intended for producing dental prostheses or prosthesis parts from polymerisable plastic. The flowable plastic is poured into a cavity which corresponds to the shape of the prosthesis and is delimited on the one hand by the gypsum model (3) and on the other hand by a duplicating gel (4) which holds the set of teeth (14) and entirely surrounds the free surfaces of the gypsum model and is polymerised in this mould in a temperature-controlled polymerisation bath. In order to achieve an extremely accurate transfer of the gypsum model surface to the plastics prosthesis and to maintain the latter free of stress, a lower pressure than the ambient pressure is maintained on the gypsum model (3) during polymerisation. To this end at least one opening (6) is arranged in the base plate (5) of the cell (2), which base plate (5) carries the gypsum model (3), in the region of the gypsum model attachment (7), and this opening (6) is connected to the atmosphere outside the polymerisation vessel (1). In another embodiment of the device for carrying out the process, at least one opening is arranged in the base plate of the cell, which base plate carries the gypsum model, in the region of the gypsum model attachment. The opening leads to a chamber which is also arranged in the base plate or into a cavity which is open to the gypsum model. <IMAGE>

Inventor: STEINSTRASSER FRANK DIPL-ING D
IPC: B01D5/00
Filed: 1987-06-30
Granted: 1989-03-23
Abstract: A plant for the pyrolysis of waste material containing hydrocarbons has a cooling stage. In this cooling stage, the hot pyrolysis gas coming from the pyrolysis reactor is cooled by direct heat exchange with low-boiling pyrolysis oil which is obtained in a further cooling stage by condensation of pyrolysis gas. For this purpose, a multiplicity of spray nozzles disposed in the form of a ring are provided in the heat exchange channel of the cooling stage, with a spray direction of the nozzles pointing substantially downwards. The end of the hot gas line which connects the cooling stage to the pyrolysis reactor is located above the spray nozzles. At the same time, feed lines for a protective, buffer or blanketing gas end in this region. In addition, an annular channel encloses the heat exchange channel and has orifices in the inner wall surface of the heat exchange channel, so that pyrolysis oil fed through the line cools and wets the wall of the heat exchange channel. This structure avoids the deposition of tar constituents from the pyrolysis gas on the wall of the heat exchange channel, while the hot pyrolysis gas is well cooled.

Title: Clarifying apparatus for biological waste water purification having an immersed trickling filter
IPC: C02F3/08
Filed: 1988-07-09
Granted: 1990-02-15
Abstract: A clarifying apparatus having a rotatably driven immersed trickling filter 5 (rotating biological contactor; RBC), which is only partly immersed in a water/activated sludge mixture, which immersed trickling filter is force-aerated by bucket-like chambers 3 circulating in an elevator-like manner, which chambers take up air during their circuit and release it at the bottom circuit region in order to take up liquid which trickles down onto the rotating biological contactor in the upper circuit region. Since the circulating chambers also serve as growth surface for microorganisms, oxygen is effectively fed to these outside the liquid with a residence time adjustable as desired. <IMAGE>

Title: Transdermal system per admin. of galanthamine - esp. for treatment of Alzheimer's disease and alcohol addiction
Inventor: HILLE THOMAS DR
IPC: A61K9/70
Filed: 1993-01-23
Granted: 1994-02-03
Abstract: Transdermal therapeutic system (TTS) for admin. of galanthamine to skin comprises (a) a backing layer which is impermeable to active agent; and (b) an adhesive reservoir layer comprising 40-80 wt.% of polyacrylate, 0.1-30 wt.% of softener and 0.1-30 wt.% of galanthamine base (or a salt). The reservoir layer consists of a polymer matrix and active agent. The polymer is, e.g., rubber (or similar homo-, co- or block-polymers), polyacrylate esters (and their copolymers), polyurethanes and silicones. The reservoir layer also comprises 0.1-30 wt.% of penetration enhancer, esp. a carboxylic acid. The polyacrylate is a polymerisation prod. of (meth)acrylic acid (or their esters). The acrylate ester's alcohol component contains 2-4 or 4-10C. The alcohol component of methacrylate ester is an aminoalcohol. The system is coated with a protective layer. The TTS may be prepd. by: (a) forming a homogeneous mixt. of the active agent and the other components of the reservoir layer; (b) coating this on the backing layer; (c) opt. removal of the solvent(s); and (d) opt. covering the TTS with a protective layer. USE/ADVANTAGE - Galanthamine is esp. useful for treatment of glaucoma, Alzheimer's disease, alcohol addiction, and as a curare-antidote. The TTS allows controlled admin. of galanthamine over at least 24 hrs. It is esp. suitable for treatment over a long period of time, e.g. of alcohol addiction. In an example, a TTS contained a reservoir layer (contg. galanthamine (10%), neutral polyacrylate (59%), polymethacrylate (15%), oleyl alcohol (softener) (5%), and oleic acid (10%) and dexpanthene (1%) as penetration enhancer) and released 18.5 mg/16 cm2 in 24 hrs. Penetration in mice amounted to 1.05 mg/16 cm2 per 24 hrs.
Patent DE-4338307-C1 (DE)
IPC: G01N21/86
Filed: 1993-11-10
Granted: 1995-05-18
Abstract: The invention concerns a process for the optical detection of objects or object streams whose surfaces can reflect or scatter light and which have autoaffine, autosimilar or fractal patterns or structures on their surfaces or within themselves, or can form or engender such patterns. The process involves the use of a lighting system to illuminate the objects or object streams in question and an optical imaging and receiving system with, downstream of the latter, an electronic system for the reception and evaluation of the imaging light reflected or scattered from the surfaces. The imaging beam is scanned in a series of optical patterns, the scanning process being based on a similarity-transformation algorithm so that combination of the individual optical patterns is spatially and/or chronologically an autoaffine, autosimilar or fractal scaling, rotation or translation and at least two variables are set. At each stage of the scaling, rotation or translation, the detection events obtained from the scanning process via the variables are recorded and updated in a storage device to produce value pairs. The logarithms of the scaling, rotation or translation variables are used to calculate the scaling, translation or rotation function (for example, where the underlying operation is scaling and the objects or object flows have autosimilarity, the value pairs are related by a linear function).

Title: Heat utilisation system in coal=fired steam generator flue
Inventor: GARLING EICKE
IPC: F22D1/36
Filed: 1994-11-22
Granted: 1996-01-04
Abstract: Heat recovered from the exhaust gas is used to pre-heat the combustion air for the steam-generator, and also in the water-steam circuit of the generator. A heat-transfer system, esp. with a rotary air pre-heater, incorporates an exhaust-gas bypass containing a heat-exchanger (10) forming part of the water-steam circuit. Part at least of the heat recovered by this exchanger is regulated (21,25) and passed via the regulating one (4) to the incoming combustion air (5). The regulating exchanger can be an air-to-water exchanger so that heat is delivered directly to the combustion air. Where one stage of the bypass exchanger can be used as a steam-generator, the regulating one can be supplied with water from the steam-generator water circuit.
