Title: Ball mill for light materials - has circular grinding chamber with reflecting and rising surfaces on its peripheral part
Inventor: NISHIYA MITSUO
IPC: B02C17/14
Filed: 1978-09-29
Abstract: The external peripheral wall (1b) of the grinding chamber (1) has part of its surface contracted towards the central collar (6). This contracted part (1d) is followed by a vertical surface (1e). The contracted part (1d) causes the material to deflect resulting in an increased pressure between the material particles and increased disintegrating effect. The flow of material reaches a high point inside the grinding chamber (1) in an area between the external wall part (1b) and the internal wall part (1c). From there the material hits the inner wall (1c) in its upper part. The grinder has a central inset element (6) seated rotatingly on the inner wall (1c) of the chamber (1). The external surface of the element (6) has a number of deflecting vanes (7).

Title: Filter for continuous thermoplastics extruder - has successive sieve chambers pushed progressively across outflowing stream without clogging risk
Inventor: KREYENBORG JOACHIM
IPC: B29C48/03
Filed: 1979-10-24
Abstract: Filter assembly for plastics extruders and injection moulding machines is intended for continuous processing or extrusion of thermoplastics and has a sieve bolt slidable transversely to the extruder channel and containing a series of sieve chambers each containing a sieve. The sieve bolt is mounted sealed and under suction in the transverse passage across the extruder and there is a vent valve adjacent to the next sieve chamber to come into use. On both the upstream and the downstream sides of the sieve chambers (sieve bolts) there are tapered overflow ducts; the overflow duct on the upstream side is of such a form that it makes a communication between the extruder barrel and the next sieve chamber, which is just about to come into use, before the corresponding duct on the downstream side of this chamber. The sieve bolt operates on the known principle, i.e. it is moved transversely across the extruder as a fall in pressure on the downstream side of the sieve chamber at present in use indicates progressive clogging of this sieve.

Title: Sulphur nitride cpds. and polymer prodn. - by reducing nitrate or halide, the polymers being useful as semiconductors
Inventor: BANISTER ARTHUR JAMES
IPC: C01B21/093
Filed: 1979-10-25
Abstract: Prodn. of S-N cpds. (I) involves the redn. of SaNbXc (II) (in which X is a monovalent of l/n ton-valent gp. a >= b and a >= c. a >=6. PRef. X is NO3 or halogen, esp. Cl and B >= c). The process is useful for making cpds. with S-N gps., cpds. contg. S-N gps., e.g. S4N4, S5N5 salts and poly(S-N) cpds. The poly(S-N) cpds. include halogenated derivs., which are metal-free electrically conductive polymers and can be compressed to black semiconductors similar to graphite. In many cases, the electrical resistance rises to a max. with voltage and then falls again with further increase in the voltage. Some of superconducting at low temps. They are useful as contact material in Schottky diodes, e.g. in GaAs solar cells. (II) is NSX, S3N3X3, S4N3+, S5N5X, S6N4X2, S4N3Cl or S3N2Cl. The reducing agent is a metal or reducing anion, pref. Fe, Ag, Ti, a chalcogenide, iodide, oxalate, hypophosphite, thiosulphate or metabisulphite, and is used in non-aq. suspension or soln. Redn. can be carried out in the presence of a reagent which reacts with the S4N4 formed to give another cpd. contg. a -S-N-gp. For the prodn. of (SaNbIc)x (which are new cpds.) (in which b=1.9-2.3 (2.1-2.3). c=0.4-1.3 (0.4-0.6). x is large), S4N3Cl vapour is mixed with an iodide and then cooled to room temp., the iodide being kept at min. 150 (min. 200) degrees C and being in the form of a salt. For the prodn. of poly(sulphur nitride), S4N3Cl vapour is mixed with Ag2S (at least 250 degrees C) and/or Ag2Te, then the vapour is condensed to form S2N2, which is then polymerised at room temp. The Ag2S used is obtd. by contacting Ag with S4N3Cl vapour. Poly (sulphur nitride) can also be prepd. by heating S5N5Fe Cl4 at min. 100 degrees C in an inert atmos. and condensing the resultant vapous, pref. at -100 to +20 (0 to 15) degrees C, the vapour pref. being contacted with Ag before condensn., which is carried out on a cooled surface. 0.10 g (0.63 mmole) S3N2Cl were triturated with 0.12 g (0.75 mmole) dry NaI at 20 degrees C. After 15 min, S3N2Cl was no longer present and the mixt. contained S4N4. Extn. wit dioxane gave S4N4, I2 and hydrolysis prods.

Patent DE-2949889-A1 (DE)
Title: Drum washing machine friction damper - produces differential damping effect by friction ring and friction lining
Inventor: BARTH ERICH
IPC: F16F7/08
Filed: 1979-12-12
Abstract: A friction damper for the vibration of rotating appliances such as front-loading drum washing machines consists of a spring loaded disc with a rim which rotates with the machinery. A U-shaped sliding ring which holds a friction lining ring has a smaller coefficient of friction on the disc than the friction lining on the stationery face which it contacts. Under normal conditions, the sliding ring will thus slide down until it rests on the rim of the disc and only little friction damping is produced. Excessive resonant vibrations force the friction lining to move and produce a much larger damping effect.

Title: Rotary drum furnace for calcining limestone or dolomite - where contamination of calcined prod. by chromium in steel drum is prevented using indirect heating system
Inventor: UTZ RICHARD
IPC: F27B7/02
Filed: 1980-02-21
Abstract: The furnace is used for calcining materials which contain CaCO3 and/or MgCO3, and consists of two chambers (9, 24) sepd. by a gas lock (23). Chamber (9) is pref. used for calcining, whereas chamber (24) is pref. used for cooling. The pref. gas lock (23) consists of a helix divided into four segments, each contg. a ball valve so the material being calcined can pass into chamber (24) but not the gas. For calcining dolomite, chamber (9) is pref. heated to 800-1200 deg.C so decompsn. of the dolomite occurs in a CO2 atmos.; but chamber (24) is used for cooling the calcined material in the absence of CO2 and from below 900 deg.C. In conventional drum furnaces, Cr from the steel used to mfr. the drum enters the calcined prod. as a chromate, which subsequently causes environmental pollution when the prod. is treated with water. The invention provides a furnace which is indirectly heated; Cr pick-up from the furnace is avoided; and the energy required is reduced from 900 kcal/kg CaO to 820 kcal/kg CaO by using a drum with a double wall.
