Title: Appts. for mfr. of rubber mixes in cooled internal mixer without RAM - with increased upper casing-to-rotor clearance with radial pins improving cooling and distribution of reactive additives and avoiding piling-up in feed
Inventor: PETER JULIUS DR
IPC: B29B7/18
Filed: 1991-08-16
Abstract: Arrangement for mfr. of rubber mixed, where a conventional batch internal mixer mixes in unreactive constituents, which are dropped directly into a similar mixer, but without a ram to apply pressure. The reactive constituents are then mixed in and simultaneously cooled. The upper part of the casing of the open mixer has increased clearance on the rotors, with parts projecting across this clearance. The projecting parts may be round pins, pref. of dia. equal to the maximum clearance, knives or cup-shaped. The pins pref. project close to the swept circle of the rotor lobe. The pins are pref. in rows parallel to the rotor axes and may be staggered in ajoining rows. There may be up to 20 pins in each row, according to machine size, pref. four in each of two rows on both sides of the machine. The rotor-to-casing clearance is pref. 1% of the interaxis distance in the lower part increasing gradually from the common plane of the axes (mid-height) to 5% of the interaxis distance at the feed opening, with pins of corresponding lengths. ADVANTAGE - The pins delay and break up the ciculating flow of material, avoiding piling up in the feed opening. This gives improved distribution, esp. of reactive components, and improved cooling.

Title: Measuring chamber for determining alpha activity of radon gas in carrier gas esp. air - has detector producing measurement signal for detecting alpha particles produced with radon conversion in chamber and unit for producing electric field.
Inventor: GAST HEINZ DR RER NAT
IPC: G01T1/169
Filed: 1992-01-09
Abstract: The unit for producing the electric field (10) has at least one electret, and attracts electrically charged daughter nuclides from the effective vol., at a distance to the first detector (2, 3). This distance is greater than the range of the most energy rich alpha particles in the carrier gas, emitted by the radon daughter nuclides. The chamber (1) includes at least one further alpha detectors (4, 7, 8), producing a measurement signal (M2). This detector is so arranged in the chamber, that it can detect alpha particles which are emitted from charged radon daughter nuclides, sucked from the effective vol. of the detector (2, 3) producing the first measurement signal (M1). The further detector detects alpha particles which are emitted from the radon itself and uncharged radon daughter nuclides. It has a smaller detection sensitivity than the first detector (2, 3). ADVANTAGE - Gives quicker and more exact determination of alpha activity of radon in carrier gas than units of this type hitherto.

Filed: 1992-02-28
Abstract: The invention relates to a device for controlling the packaging means feed to a sweet packing machine dependently upon the level of the contents of the pairs of holders of a sweet conveyor. According to the invention, a pair of control cams (26, 27) divided into an inner and an outer cam half (26', 27', 26'', 27'') is formed as a compact set of cams to control a moving extractor roll (5) for the packaging feed and the inner and outer cam halves are solidly coupled but relatively rotatable to adjust the cam intersections (saddle points) (36, 36'). This provides a particularly compact construction and the accurate feed of packaging means which avoids losses of packaging means, the actual presence of sweets between the pairs of holders of the sweet conveyor being detected.

Title: Determn. of nitrite formation in biochemical reactions - by using stable isotope nitrogen =15 as marker and determining its content in reaction prods. using mass spectroscopy
Inventor: JUNGHANS PETER DR
IPC: G01N33/483
Filed: 1992-07-28
Abstract: Process involving marking of the reaction cpds. with stabile nitrogen-15 (15N). The process involves measuring gaseous nitrogen produced by the reaction and determining the quantity of 15N. Any reduction in 15N is as a result of 15N being combined in the reaction products (e.g. nitrites, amino-cpds.). In the gas tight process container (6) in which any reactions take place any un-marked nitrogen in the air is first driven off using a cleaner or transport gas (1). The rate of flow of the transport gas (1) is measured in a flow meter (5) prior to the process container (6). The reactants (e.g. nitric acid (3), aliphatic amine-cpds. (4)) and 15N tracer (e.g. 15N marked nitrite) are injected into the process container (6). In a measuring arrangement (7) the quantity of 15N can be determined by mass spectroscopy. USE/ADVANTAGE - Determines nitrous cpd. formation in a biochemical reaction. With the development of routine processes for the determn. of isotope concn. (e.g. mass spectroscopy) non-radioactive isotope tracing is possible. The claimed process is easier and cheaper to carry out than alternative chemical methods or processes involving the radioactive isotope 13N (with the attendant disadvantages of radioactive radiation and short half-life).
