Patent DE-2819127-A1 (DE)
Title: Testing chemical and biological substances for harmful effects - to eliminate them, by determn. of number of plasma-polyps in blood plasma
Inventor: THORN WERNER PROF DR
IPC: G01N33/02
Filed: 1978-04-29
Abstract: A process for testing chemical and biological substances (suitable for pharmaceuticals, foodstuffs, insecticides, pesticides, solvents and other goods in daily use) for harmful effects, and for eliminating these side-effects was described in the parent patent. The substance to be tested is administered to experimental animals and after sufficient time the number of plasmapolyp labelled cellorganell-poor protrusions in the blood plasma or in histological slices from tissue is determined and by positive precipitation, the substance being tested is combined with a cpd. which reduces the formation of plasmapolyps. The plasma polyp number in the blood plasma is determined by; (a) the heavy blood cells are sepd. by partitioning the sample with a soln. of a copolymer of sucrose and epichlorohydrin (m.wt. ca 70000) and centrifuging; (b) sepg. the plasma polyps in the sample freed from heavy blood cells by diluting with physiological salin centrifuging and sepg. the sediment; (c) diluting this sediment with Krebs-Ringer soln. centrifuging and sepg. to further enrich the sediment, so that the centrifuge rate increase from step (a) to step (c); and (d) counting the plasma polyps in the sediment from (c) by resuspending and observing in a phase contrast microscrope. The determination of plasma polyps is simplified and the time necessary is reduced. The margin of error in step (d) is below 0.19.

Title: Pharmaceutical preparations in retard form - with active materials in core having semipermeable coating of film former and polymer
Inventor: STRICKER HERBERT DR
IPC: A61K31/55
Filed: 1978-08-19
Abstract: Pharmaceutical prepn. in retard form comprises a core contg. >=1 active substance together with a carrier or excipient. The core is coated with a semipermeable coating of 20-90% water-insoluble film former (I) (e.g. ethyl cellulose) and 10-80% water-soluble polymer (II), e.g. PVP, PEG or methyl cellulose. The release of active substance is independent of pH in the body fluid over the whole period of its activity. The core pH may be reduced by inclusion of acidic material to reduce disintegration time. Dosage regimens are simplified, and initial very high blood levels may be avoided. The core may be in the form of a tablet. The coating pref. has the same permeability over its whole surface. The core may contain an organic food acid to reduce the disintegration time of the core, e.g. citric or tartaric acid is used. The coating may also contain up to 70% water insol. polymer e.g. cellulose acetate.

Patent DE-2841857-A1 (DE)
Title: Oscillation suppression system for furnace - prevents arc-furnace electrode-arm oscillating, by reducing proportional gain of impedance controller according to arc current fluctuation
Inventor: TRAUTH GUNTER DIPL ING
IPC: H05B7/148
Filed: 1978-09-26
Abstract: The suppression system prevents the arm supporting the electrode of an arc furnace from oscillating as a result of periodic fluctuations in the arc current. (Such oscillations can cause the electrode to break). The proportional gain of the impedance controller is reduced depending on the fluctuations in arc current. To this end, the control difference is passed to the controller via an attenuator that reduces it by an amount depending ondthe periodic fluctuations superimposed on the control difference.

Title: Desulphurising of gases - by combustion with air in fluidised bed of limestone and coal
Inventor: MENGIS WOLFGANG DIPL ING
IPC: B01D53/12
Filed: 1978-11-11

Title: Heat exchanger housing inserted between two sections of exhaust - recovers waste heat with by=pass regulated via temp. sensors and computing mechanism
IPC: F28D21/00
Filed: 1978-12-18
Abstract: The heat exchanger is mounted in a unit which is inserted between two sections of an exhaust system in order to use the waste heat. It can be used in flue gas pipes or hot waste water exhaust systems. It functions in conjunction with a bypass which regulates the amount of waste energy flowing through the unit. The control of the bypass is regulated by the signals derived from temperature sensors. One temperature sensor is connected to a signal generator which is operated at a threshold value of temperature. Another temperature sensor feeds into a computing device which operates at the limiting values and intermediate values of the temperature.

Title: Damp-proof foam-insulated sandwich wall structure - joins adjacent section cores by tubular sack foam filled in situ
Inventor: BECHER KARL
IPC: E04B1/61
Filed: 1979-03-14
Abstract: An insert for connecting >=2 wall structures and end faces of which are aligned closely to each other, consists of a tubular hose of PVC or polyethylene film, for pref. 0.03 mm thick, and filled with expanded polystyrene or polyethylene. The structures are cavity walls of concrete enclosing a foam insulating layer and a damp excluding layer of synthetic foam, bitumin, etc. The damp excluding layers of two adjacent structures extend beyond the edges of the corresponding insulating layers which are themselves set back from the edges of the wall shells and making room for the insert. Arrangement ensures a reliable connection of the damp excluding arrangements to each other and an insulation without holes. The design is simpler and more pleasing in appearance without it being necessary to fit asbestos cement sheets because of the ready-made inserts used elsewhere.
Patent DE-2913113-A1 (DE)
Title: Solid rubber tyre - with cross slots on inside for tangential anchorage by bosses on clamp rings
Inventor: MUELLER SIEGFRIED DIPL ING
IPC: B60C7/28
Filed: 1979-04-02
Abstract: Elastic solid tyre, esp one made of rubber, for a wheel, has an upper part of the section of a trapezium, and a lower part of curved contours and greater width. Two clamp rings shaped to suit these curved contours are bolted to the wheel disc and press the tyre together. In addn. the solid tyre has on its inner periphery short slots with a rounded bottom right across. Bosses on the inside of each ring fit into then to act as additional tangential anchorage. Advantages are an axial and a tangential anchorage which prevents premature destruction of the tyre by shear forces due to power transfer. New design also ensures a better dissipation of developed heat.

Title: Multiple track chart recorder - has alternately staggered pens and compensating signal processing delays
Inventor: LEONHARD HELMUT
IPC: G01D9/30
Filed: 1979-08-22
Abstract: The multiple track chart recorder displays two or more measurement parameter amplitude variations synchronously and side by side on a strip recording medium (2). It eliminates the recording distortion and sensitivity degradation imposed by mechanical or electronic limits used in conventional arrangements to prevent contact between adjacent pens. The parameters are divided into two groups with alternating tracks (A1,A2 etc) for one group and another set of alternating tracks (B1,B2 etc) for the other. The points of recording (3A,3B) for the two groups are separated by a defined distance (a) along the chart. The second group with its recording point (3B) after that of the first has an associated signal processing stage delay related to the separation distance (a) and the chart speed.

Title: Solar heating system using silicon plates - has each plate electrically insulated from circulating water by glass outer layer
Inventor: BAUER HEINER
IPC: H01L31/052
Filed: 1979-09-06
Abstract: The solar heating system has silicon plates (4) which can be mounted at an angle or parallel to vertical walls or balconies. The plates are enclosed by housings (6) through which water (8) is circulated. The water falls from an upper level to a lower level without pumping, and turbulence can be increased by horizontal projections (9) inside the housing. These plates can be electrically insulated from the circulating water by a glass covering plate (10). In another design, each plate (4) can be enclosed between an inner plate (13) and an outer plate (12) forming a chamber separate from the water circulating chamber. Further heat can be extracted from the unit by a suction device such as an extractor fan (14).
