(I) is aq. dispersion contg. at least 40, pref. 85-99.5 wt.% water. (I) contains mineral oil-based additive for binding dust, partic. in ratio oil:(I) 5:1-1:5, esp. 2:1. USE/ADVANTAGE - Impregnating mineral fibres at 0.1-2, pref. 0.2-1, wt.% on wt. of fibres partic. for use for insulating purposes. (I) is silicone-free, artificial mineral fibres can be simply and effectively impregnated permanently by (I) together with dust-binding agents, smoothing agents, and lubricants, and impregnated materials do not readily absorb water, so retaining insulating efficiency. In an example, a homogeneous emulsion was prepd. from 5 l Experimental Latex Dispersion XZ 947.40.00 (TM: dispersion, solids content 46.6%, of a (II)) and 4.8 kg mineral oil by mixing for 10-15 minutes, opt. with warming at up to 50 deg.C. Emulsion was then diluted with water to 2%. In prepn. of glass fibres by jet blasting, the diluted emulsion was sprayed onto the glass fibre jet such that the (I) concn. was 0.3% (oil 0.2%, copolymer 0.1%) on the fibres, the fibres being cooled to under 200 deg.C and (II) immediately crosslinking. Testpieces 500 X 500 X 40 mm thick were prepd., having apparent density 24.4 kg/m3, from the impregnated fibres. In water uptake tests involving flotation, immersion, or dipping into water, the samples proved sufficiently hydrophobic.

Title: HDPE prodn. - with procedure for changing process parameters to enable changeover from high-mol. wt. to low-mol. wt. HDPE without shut-down or cleaning
Inventor: FRITZSCHE GERD DIPL CHEM
IPC: C08F110/02
Filed: 1992-12-10
Abstract: A process is claimed for the prodn. of HDPE by catalytic gas-phase polymerisation of a mixt. of ethylene, hydrogen and comonomer (e.g. butene-1) in a fluid-bed reactor incorporating a gas distributor, with recirculation of unreacted gas mixt.. The special feature is that, from the steady-stage condition for prodn. of a polymer suitable for the mfr. of large tubular prods. (HDPE-I), the system can be changed over directly to reaction conditions for the prodn. of a polymer suitable for the mfr. of paper-like film, small hollow prods. and tubing (HDPE-II) without shutting down or cleaning the system. This process comprises: (a) raising the hydrogen concn. in the gas circulation to a level corresp. to a hydrogen/ethylene ratio of 45-55 x 10 power(-3) mole/mole 36-42 hrs. before changeover, at a temp. of 84-96 deg.C and with continuous removal of off-gas at the rate of 1.7-5.1 x 10 power(-3) Nm3/m3 circulating gas, (b) interrupting the addn. of catalyst, (c) stopping addn. of hydrogen until the hydrogen/ethylene ratio in the gas circulation falls to 30-36 x 10 power(-3) mole/mole starting at the same time as (b), (d) increasing the amt. of butene-1 in the circulating gas to a typical level for HDPE-II (at the same time as (b) and (c)), (e) lowering the reactor fill height to 90-94% of the normal level gradually over 1.5 hrs. (simultaneously with (b)), (f) raising the reactor temp. gradually to a level suitable for HDPE-II prodn., starting with (b), (g) resuming addn. of catalyst 3 hrs. after (b), (h) increasing the reactor level to 110-114% of normal for 15-35 mins. after stage (g), and (i) re-establishing the normal reactor level. USE/ADVANTAGE - The invention makes it possible to convert a continuous gas-phase HDPE prodn. system directly from prodn. of high-mol. wt. polymer to prodn. of low-mol. wt., pinhole-free polymer (mol. wt. 300,000) without shutting down or cleaning the system. This process reduces the amt. of transitional polymer with pinholes and inhomogeneities which are normally obtd. after changeover.

IPC: A47G19/22
Filed: 1993-02-16
Abstract: The invention relates to an open drinking vessel, preferably to a cup, having a substantially plane base and an annular edge projecting downwards beyond the base. Provided in this edge are arcuate indentations which are distributed uniformally over its circumference, which taper to a point from the bottom upwards and the ends of which, likewise preferably terminating in a point downwards, form small feet which serve for standing the vessel on an underlying surface. The edge of the vessel which projects downwards beyond the base may have a smaller diameter than the vessel itself and the arcuate indentations may be of an arcade-like shape over the circumference of the edge. It is advantageous if in the wall between the arcs vertically running narrow ribs are provided which run upwards into the wall of the vessel, and if the wall in the region of the arcs is also indented from the outside inwards. In a particularly advantageous embodiment of the invention, a cup provided with small feet is combined with a saucer which has an elevated central part used for standing the cup, the central part having an annular edge in which there are provided recesses serving for the drainage of liquid collecting on the central part into the annular space between the edge of the saucer and the central part.
