Two winding spindles (5.1, 5.2) are mounted on the bobbin turret (18) of the winding machine. The particular winding spindle which is in operation bears with its bobbin against a contact roller (11). With an increase in bobbin diameter, the bobbin turret (18) is rotated in dependence on a slight deflecting movement of the contact roller (11). The position of the contact roller remains essentially ...

Fluid from a producing well is accumulated in an accumulator (10) and allowed to separate into free water, a water-continuous phase and an oil-continuous phase; the separated fluid flows through a monitor (30) having electrodes (104-106;152-157) exposed to the fluid; a power source (125) provides an AC voltage and current to the electrodes and provides an injection voltage signal (Vi) and an injec...

The Bipolar Battery Construction disclosed and claimed above solves the problem of constructing a bipolar battery (11,12) with a desired, uniform, constant, pressure between each bipolar plate (20) and separator (30) in the battery cell stack (48). The provision of such a pressure dramatically increases battery life, and increases the power of the cell stack (48). Compressive force is provided by ...

Process for the preparation of a fine celled open celled rigid polyurethane or urethane-modified polyisocyanurate foam comprising the step of reacting an organic polyisocyanate with a polyfunctional isocyanate-reactive material, wherein the reaction is carried out in the presence of at least one infrared absorbing substance.

A lightsafe masking film is disclosed which comprises a substrate, a pressure sensitive adhesive layer formed on the substrate, and a lightsafe, peelable layer formed on the adhesive layer and including a dialkyl phthalate, nitrocellulose, a lightsafe colorant and, optionally, a filler and a nitrile rubber. The peelable layer further suitably contains a dialkyl ester of an aliphatic dicarboxylic a...

Expanded articles of biodegradable plastics material are produced by the extrusion of a composition including starch, a polymer compatible with starch, in particular, an ethylene-acrylic acid copolymer and/or ethylene-vinyl alcohol copolymer, and an expanding agent. Preferably use is made of sodium bicarbonate as expanding agent in the presence of a polymeric acid.

The present invention provides a method for manufacturing an engine gasket (11) having reduced oil permeability. The engine gasket (11) is formed in the desired shape from a silicone rubber compound having an inner surface which is to be exposed to hot engine oil and an outer surface. A silicone varnish coating is applied to at least the inner surface of the engine gasket whereby the inner surface...

The invention relates to a coated film composition comprising: a) a biaxially oriented high density polyethylene (HDPE) film comprising at least 50 wt. % of HDPE having a density of 0.960 or greater; and b) a coating which is derived from the group consisting of polyvinylidene chloride polymer or copolymer, acrylic acid polymer or copolymer, and polyvinyl alcohol polymer (PVOH); and its method of ...

The invention relates to a method for testing a fitting (2a) driven by a solenoid (1a), which has a closing part (4a). It also relates to a device for testing such a fitting (2a). It is provided that during a switching process of the fitting (2a), the value of the current intensity (It) in the solenoid (1a) is recorded as operating current intensity (IA) at the time when the locking part (4a) star...
