Patent EP-0305584-A3 (EP)
IPC: C03B3/02
Filed: 1987-10-03
Abstract: 1. Verfahren zur Behandlung von Abgasen.  
         2.1. Bei der Glasherstellung anfallende Abgase werden übli­
cherweise direkt an die Atmosphäre abgegeben. Das führt zu ei­
ner Umweltbelastung mit den in den Abgasen enthaltenen Schad­
stoffkomponenten. Der Erfindung geht es nun darum, die Abgase 
vor ihrer Einleitung in die Atmosphäre einer wirtschaftlichen 
Schadstoffreduktion zu unterziehen.  
         2.2. Das erfindungsgemäße Verfahren zur Schadstoffneutralisa­
tion sieht das Hindurchleiten der zu behandelnden Abgase durch 
ein wenigstens teilweise aus Altglas (Glasscherben 20) beste­
hendes Rohstoffgemenge (17) vor. Hierdurch werden einerseits 
die wesentlichen Schadstoffkomponenten der Abgase zumindest 
teilweise beseitigt und andererseits wird bei Abkühlung der 
Abgase eine Vorwärmung des Rohstoffgemenges (17) herbeigeführt.  
  
         2.3. Das erfindungsgemäße Verfahren eignet sich besonders zur 
Behandlung von Rauchgasen aus einer Glaschmelzwanne (10) bei 
der Glasherstellung.

Patent EP-0284442-A3 (EP)
IPC: H01P1/213
Filed: 1988-03-28
Abstract: Apparatus for transferring RF signals between a plurality of 
inputs (36i) and a plurality of outputs (32j) comprises a plurality of 
output multiplexers (30₁....30₁₀), each made up of a plurality of 
hybrid/tunable filter combinations (21₁....21₈). The RF signal inputs of 
the apparatus are supplied to one output multiplexer (30₁) and the 
inputs of each output multiplexers are connected to the inputs of the 
adjacent multiplexer, such that a signal not transmitted by one 
output multiplexer will be passed to a next output multiplexer, 
and so on. By appropriate tuning of the filters (24) in the output 
and multiplexers the RF signals may be reconfigurably distributed 
between the inputs and the outputs, and, the need for switching 
is avoided whilst maintaining an acceptably low path loss.
Patent EP-0294294-A3 (EP)
Title: Amine derivatives of anthracycline antibiotics and antibody conjugates thereof
IPC: A61P31/04
Filed: 1988-06-03
Abstract: Novel antineoplastic amine-containing derivatives and methods for synthesizing such derivatives of anthracycline antibiotics are disclosed. The derivatives are useful to prepare site-selectively attached therapeutic antibody-anthracycline antibiotic conjugates which retain substantial immunospecificity of the unconjugated antibody molecule. Using the conjugates, targeted delivery of the attached antineoplastic amine derivatives of anthracycline antibiotics is achieved in vivo. Such conjugates are thus therapeutically effective against a variety of neoplastic cellular disorders when administered in vivo. Methods for preparing the antibody conjugates and for use of the conjugates in vivo are also disclosed.

Title: Apparatus for relaxation and psychosensorial stimulation
IPC: A61M21/00
Filed: 1988-01-06
Abstract: The apparatus comprises an enclosure, which is intended to create a space protected and insulated from its environment and in which the user takes up a position, and a control box which is connected to the enclosure. The control box comprises a computer, a magnetic tape reader, equipment for conditioning the air in the enclosure, an ionizer and an aroma diffuser. The enclosure is made in the form of a shell of the sandwich type, consisting of mineral wool arranged between two composite walls made of glass fibre and polyester resin, and rendered leakproof to radiation by virtue of the addition of barium sulphate to the polyester resin. A stainless steel latticework is in addition placed in one of the composite walls. A plurality of apparatuses permitting the generation of psychosensorial stimulations are arranged in the enclosure. The enclosure also comprises a heating bed contained in a synthetic container with a high thermal insulation power and containing several layers of cylinders made of rubber, inflated with air, and covered over the whole surface of the bed by a flexible and impermeable heating plate. Hollow spheres of rubber, with very thin walls, and highly deformable and containing a liquid, are distributed side by side over this plate. The bed is covered with a fine padding of synthetic cotton wool, allowing the air to circulate, and with a slip cover made of cotton with elastic meshes.
Patent EP-0333985-A3 (EP)
IPC: A62D3/00
Filed: 1989-01-17
Abstract: Under certain operating conditions, an emulsion of an 
acidified unfiltrable tarry bottoms stream from a reactor 
for the chlorination of ethylene to 1,2-dichloroethane can 
be demulsified and separated in a phase separation tank. 
The presence of FeCl₃ in an amount more than 5 ppm Fe in 
the separated organic waste, fouls the reboiler and lower 
internals of a "heavies" column in which the separated 
organic waste is concentrated, and deactivates the cata­
lyst in a Catoxid fluid bed reactor in which the concen­
trate is burned. By maintaining an iron salt chlorination 
catalyst in a concentration which results in 2000 ppm to 
4000 ppm of Fe in the HTC reactor bottoms, and operating 
the HTC reactor at a temperature in the range from about 
90°C to 120°C and a pressure in the range from 9 psig to 
12 psig, an unfiltrable reactor bottoms drawoff is produc­
ed which may be acidified without forming an emulsion. 
Formation of an emulsion is avoided by mixing each volume 
of the HTC bottoms drawoff with at least 50 volumes of 
dilute aqueous HCl in a concentration range from 2 to 4% 
so as to demulsify the emulsion into aqueous acid and 
organic phases. The mixture is gravity-separated in a 
phase separation tank by decantation. The lower layer (60-­
70% by wt EDC, the remainder being heavies) is concentrat­
ed by recovering EDC overhead and producing a bottoms 
concentrate in which the Fe is present in no more than 50 
ppm. The concentrate may be economically disposed of in a 
Catoxid reactor using a support-free gamma alumina cata­
lyst found to be highly sensitive to iron.

Filed: 1989-10-03
Abstract: Polycarbonates are blended with an impact 
modifier to improve the impact resistance thereof. The
