Abstract: The present invention refers to a method to convert H2 and CO2 into methane by methanogenic microorganisms in a bioreactor in a continuous production process for methane enriched gas compositions, while culturing the methanogenic microorganisms under cell retention conditions and continuously removing metabolic water in the cell culture medium.

Abstract: Pest electrocution device, suitable to be mounted in a pipe (2) or conduit, wherein the electrocution device comprises a ramp (30) hingely attached to a chassis (10), which chassis has means to be fastened to said pipe or conduit, where said chassis further comprises a chassis arm (11), and a tunnel element (20), which tunnel element is pivotably fastened to said chassis arm, and where the tunnel element in a first position extends to an upper end of said ramp, such that a pest travelling up the ramp can enter the tunnel element at a first end, where activating means are provided inside the tunnel element, which activation means activate at least three electrodes (70, 71, 72) by supplying electrical current to said electrodes arranged as separate floor plates in the tunnel, such that after activation and a predetermined period of time, the tunnel element pivots the first end downwards into a second position, in which second position the electrocuted pest slides out of the tunnel element, after which the tunne

Abstract: Described are a hybrid yarn consisting of two groups of filaments, one group consisting of one or more varieties of reinforcing filaments (filaments (A)) and the other group consisting of one or more varieties of matrix filaments (filaments (B)), whereinthe filaments (A) of the first group have an initial modulus of above 600 cN/tex, preferably of 800 to 25,000 cN/tex, in particular of 2,000 to 20,000 cN/tex,a tenacity of above 60 cN/tex, preferably of 80 to 220 cN/tex, in particular of 100 to 200 cN/tex, and a breaking extension of 0.01 to 20%, preferably of 0.1 to 7.0%, in particular of 1.0 to 5.0%,the filaments (B) of the second group are thermoplastic filaments which have a melting point which is at least 10.degree. C., preferably 20.degree. to 100.degree. C., in particular 30.degree. to 70.degree. C.

Abstract: Described is a hybrid yarn consisting of at least two varieties of filaments, at least one variety (A) having a lower heat shrinkage and at least one variety (B) a higher heat shrinkage than the rest of the filaments of the hybrid yarn, whereinthe first variety (A) of filaments has a dry heat shrinkage maximum of below 7.5%,the second variety (B) of filaments has a dry heat shrinkage maximum of above 10%, andits dry heat shrinkage tension maximum is so large that the total shrinkage force of the proportion of the second variety of filaments is sufficient to force the lower-shrinking filaments present to undergo crimping,the optionally present, further filament varieties (C) have dry heat shrinkage maxima within the range from 2 to 200%and at least one of the filament varieties (B) and/or (C) is a thermoplastic filament whose melting point is at least 10.degree. C., preferably 20.degree. to 100.degree. C., in particular 30.degree. to 70.degree. C.

Abstract: A self-adhesive acrylate copolymer is provided which can be used to prepare self-adhesive webs. The acrylate copolymer is prepared by a combined suspension and emulsion polymerization.
