In the case of a novel storage battery (accumulator), there are two current busbars, which collect the surge-arresting lugs of the electrodes and are usually arranged symmetrically with respect to one another near to the edges of the plate pack. That current busbar having the one polarity is located above the centre of the plate pack and that current busbar having the other polarity is located alo...

Recycling of compact or porous (e.g. foamed) plastics consisting wholly or partly of polyurethane is effected by working-up the starting material to give a mixt. of low OH no. and then conventionally converting this to the end-prods.. The process comprises (i) either (a) swelling the starting material (e.g. polyurethane scrap) in a suitable swelling agent and processing it to give a flowable gel p...

An air-operated combination diaphragm spring brake has a tamper-resistant seal provided between a head (46) and a spring side of a flange case (18) which together form a spring chamber (16) housing a power spring (72). The head (46) has an annular rim (70), and the flange case has an annular flange (74) with a diaphragm (48) sandwiched therebetween. An annular lip (76) on annular rim (70) extends ...

The invention relates to a composite membrane with a porous polymer support layer and a polymer top layer, whereby the porous polymer support layer is of polyacrylonitrile (PAN), polyacrylamide, polyetheretherketone (PEEK), polyetherketone (PEK), polysulfon or polyethersulfon, whereas the polymer top layer is a dense layer comprising polyvinyl chloride with selective water permeability. Preferably...

The film is obtained directly by extrusion from the lactic acid-based polymer plasticised beforehand by incorporation of 5 to 30% by weight of the polymer of a glycerol ester obtained from an acid containing 4 carbon atoms in its molecule. The film has an elongation at break of more than 300% and is particularly suitable for the production of medical dressings.

The present invention provides a process for making a cured plastics moulding by introducing a pre-heated curable resin composition to a hotter mould which is at a temperature high enough to initiate curing of the resin, and supplying further resin under pressure to compensate for shrinkage of the composition, wherein the curable resin is an epoxy resin formulation comprising an epoxy resin contai...

The appropriate one of a list of possible motion vectors is applied to each region of a video image. An image value for that region is determined for each of four successive fields, for each of the possible motion vectors. The values for the four fields are compared and when the values are substantially the same for a given vector it is assumed that that is the vector apppropriate to that region. ...

Implant bodies are mfd. by placing ceramic powder inside a 3-D changeable mould, and compacting the powder in the mould prior to subjecting to cold isostatic pressing. The green body produced is removed from the mould and its dimensions are such that after undergoing sintering, the shrinkage caused produces a body with the required final dimensions.

The plaster or rendering composition contains binders, aggregates and conventional additives, and also from 0.1 to 1.5 kg/t of aluminium powder from 1 to 30 kg/t of powdered sodium and/or potassium water glass, and from 0 to 30 kg/t of quicklime. n

Heavily filled UV-curable epoxy resin compounds are proposed for the drop-type covering of, in particular, unencapsulated electrical and electronic circuits and devices. Compared with the thermally cured catalysed resins hitherto used, which were mainly of the 2-component type, these coverings, are better in terms of handling and properties.
