A method of producing PVC foam wall covering consisting of plastic layers with textile backing uses a temporary carrier consisting of releasable paper in the process. The plastic (laminate) layer is first separated from the paper taking care that no longitudinal tension is introduced in the layer. After this, the adhesive-coated textile layer is applied to the side from which the paper has been re...

A liquid absorbing pad, in particular for use in hygiene articles and sanitary products, such as diapers, bed pads, sanitary napkins, pads for incontinence, panty shields, nursing pads or the like, is produced in a dry and direct process on the basis of wet-strength and/or coated paper waste, especially originating from the production of food packages, milk carton packages, deep-freeze packages, d...

The invention relates to a method for determining the spatial content of spaces, especially subterranean spaces, such as for example cavities, caverns, caves and the like. The essence of the invention resides in the fact that the volume of a medium filling the space being studied is changed by a sudden and short-lived increase or decrease in volume. In this arrangement, the pressure prevailing in ...

A plate stack clamping element is formed of adjacent leaf springs preformed to diverge where they extend beyond the plate stack. Compression of the diverging portions creates large area contact clamping force against the plate stack.

A continuous marine pipe laying system utilizes two rollers to overbend and straighten pipe as it is unwound from a reel. A support arm is pivotally connected to the axis of rotation of said reel and first and second roller arms are pivotally connected to the support arm at a point spaced from said axis of rotation. During use, the first roller is positioned at a point adjacent the pipe substantia...

An electronic apparatus comprising a memory and a memory backup power source for supplying power to the memory when normal power supply to the apparatus is interrupted; wherein after resumption of normal power supply to the apparatus, and error signal is generated when the voltage of the memory backup power source is below a predetermined value, indicating that the content of the memory is not rel...

The locations of defects in flat glass (1) are detected during conveyance through a detection station where the glass is scanned by a radiation beam (11). The beam sweeps transversely across the path of the glass through a distance in excess of the glass width so that the beam sweeps through both side edges. Beam deflection occurs when the beam encounters a side edge boundary of the glass (1) and ...

A method and apparatus for use at the stage of a radial tire building process at which a tread and breaker, and sidewall rubbers, are added to the expanded carcass. A tread assembly is built, comprising tread rubber breaker and sidewall rubbers and is then located around the carcass which is then expanded into the tread assembly. A tread assembly former has a central portion expansible to bring si...

The invention is a novel hydroxyl-group containing component useful in the formation of polyurethane foam, a polyurethane foam and a process for making polyurethane foam using the novel hydroxyl-group containing component and an insulated container and a process for making an insulated container using polyurethane foam formed from the novel hydroxyl-group containing component.

The invention provides a speed changing apparatus for a working vehicle comprising branched transmission lines between an input shaft and an output shaft. Each of the transmission lines includes one or more synchromesh type change speed gear mechanisms and one hydraulically operated clutch.

A method for combustion of sulfur-containing fuel in a circulating fluid bed combustion system wherein the fuel is burned in a primary combustion zone under reducing conditions and sulfur captured as alkaline sulfide. The reducing gas formed is oxidized to combustion gas which is then separated from solids containing alkaline sulfide. The separated solids are then oxidized and recycled to the prim...

A foam structure having a density of less than about 20 lbs/ft3. The method of forming the same comprising forming a homogeneous melt blend under pressure of a polymer member selected from the group consisting of polyetherimide resin particles, polycarbonate resin particles, a polymer blend of polyphenylene oxide and polystyrene in particle form imbibed with a blowing agent, followed by extrusion ...

Novel fiber fabric laminates impregnated with polyamide-imide and polyamide-imide-phthalamide copolymers are disclosed. The laminates are useful as engineering materials for the replacement of metals.

Expandable beads and the like of thermoplastic organic polymer material, advantageously lightly-crosslinked in preparation, which are imbibed with halocarbon and/or light hydrocarbon (including mixed) blowing agents are advantageously tempered to provide excellent quality, uniformly fine-celled expanded cellular products therefrom by a quick quench from imbibition temperature to below 10 or so DE...
