An arrangement and a method for a drive unit of a vehicle. The drive unit incorporates an engine, a mechanical stepped gearbox and a connecting device which is designed to transmit rotary motion from the engine to the stepped gearbox. An electric rotor machine acts upon the connecting device such that substantially no torque is transmitted from the engine to the gearbox during gear changing. A con...

A method for foaming a vinyl chloride polymer comprises heating a mixture of a polymer, a blowing agent and at least one stabiliser. The stabiliser is selected from an organotin mercaptide of a mercaptoalkyl carboxylate of formula (I) or a sulphide of (I): R1(4-y)Sn[SR2OC(O)R3]y (I) R1 = 1-8C alkyl, R2 = 2-18C alkylene radical, R3 = H, (hydroxy)hydrocarbyl or R4C(O)OR5, R4 = (CH2)2, phenylene or -...

A high clarity film containing three layers wherein the polymer of each outer layer is the same or different polyethylene selected from polyethylenes having a density of at least 0.925 g/cc, and a molecular weight distribution of less than 4, and being further characterized by being substantially free of branches having 6 or more carbon atoms, polyethylenes of the outer layers optionally containin...

A generally hydrophobic polyolefin article is provided with a modified surface by contacting said generally hydrophobic polyolefin with a copolymeric material while said polyolefin is at a temperature above its glass transition temperature. The copolymeric composition comprises a generally hydrophobic moiety and a modifying moiety. Also disclosed is a method for imparting the modified surface to a...

A process is disclosed for the preparation of a shapeable solution of cellulose in an aqueous tertiary amine-oxide from comminuted cellulose. The process includes introducing previously comminuted cellulose material into an aqueous solution of a tertiary amine-oxide to prepare an initial suspension, subjecting the initial suspension to high-consistency milling to further break-up the cellulose mat...

The invention refers to a process of forming shaped articles from starch, which process comprises: (a) heating a composition comprising a pre-processed and essentially destructurized starch/water material, at a water content in the range of from 10 to 20 % by weight based on the weight of the composition to a temperature sufficient to essentially destructure the starch. (b) transferring the me...

An optical array containing a system of absorptive filters and a system of interference filters. For the sun light the spectral characteristics of transmission of the optical array is close to the world-wide accepted Diffey Standard. That standard models human skin sensitivity to UV burning. The invention allows making inexpensive, miniature UV sensors that can be applied in a miniature devices me...

The garment consists of several layers, of which the inner facing the skin is very permeable with a low absorption factor, whilst outside it is one or more layers which have high absorption and diffusion properties and low retention for fluid. The whole is covered by a stop layer of elastic material which is impermeable to water and vapour.

The learning game is of the domino type and has a number of bricks, which are made of different wood types. The brick (1) front sides show two symbols (2a, 2b) which have a connection with the wood type of which the actual brick is made. The symbols can e.g. by a picture of a leaf from the wood type or a picture of a typical usage of the wood type, e.g. a house or a boat. The brick front side even...

A process for purifying waste water by means of activated sludge in which the waste water to be purified is taken into an aeratable sludge basin (1) followed by a sedimentation basin (5) in which the sludge and clear water are separated, whereafter sludge is taken back to the sludge basin (1) and clear water is drawn off; an operating cycle takes place in the sedimentation basin (5) several times ...
