Abstract: The invention relates to a levelling bar for coking ovens, for levelling the cones of discharged coal which form under the filling holes of the oven chamber during the filling process. The levelling bar consists of two cheeks, such as plates (1), which extend essentially over the entire length of the ranged at a distance from each other depending on the width of the oven chamber, and parallel to each other. They are also interconnected and are essentially vertical. The levelling bar also has transversal coal carriers (2) which are arranged in the intermediate space delimited by the cheeks (1) at a mutual distance, one behind the other and which only extend over part of the cross-sectional surface of the levelling bar formed between he cheeks (1). The height (3) of the coal carriers (2), which take up the entire interval between the cheeks, is less than the height (H) of the cheeks (1) and the cheek form a gas channel (6) above the coal carriers (2) which is essentially free of built-in components.

Abstract: A breathable laminate having biaxial elastic stretch, cloth-like aesthetics, and a fluid barrier is formed by bonding a breathable elastic film to a nonwoven facing material. The facing material can be inherently machine direction and cross direction stretchable, or can be necked to impart cross direction stretchability, and can be creped or crimped to impart machine direction stretchability. Alternatively, machine direction stretchability of the laminate can be achieved by bonding the elastic film in a pre-stretched condition to the facing material. The breathable laminate is particularly useful as an outer cover for diapers and other personal care products.

Abstract: An apparatus for treating wastes includes a fluidized bed reactor for partially combusting the wastes at a relatively low temperature, and a separate relatively high temperature reactor for separate gasification of gaseous material and char from the first gasification. This synthesis gas thus formed is cooled, subjected to a conversion operation in a converter to produce hydrogen.

Abstract: A gas compressor and a bypass that bypasses the gas compressor are provided between a hydrogen absorbing tank and a hydrogen gas consumer device such as, for example, a fuel cell. When the hydrogen gas generating pressure is low during an initial period of the hydrogen gas releasing operation of the hydrogen absorbing tank, the gas compressor is operated. When the hydrogen gas generating pressure of the hydrogen absorbing tank becomes sufficiently high due to normalization of the operation of the fuel cell or the like, the gas compressor is stopped, and hydrogen gas is supplied to the fuel cell via the bypass.

Abstract: A sealable lid assembly for a vacuum distillation apparatus has a lid pivotally and telescopically mounted to the vacuum distillation apparatus. Spaced-apart wheels are rotatably mounted to the lid. Tracks are disposed on the vacuum distillation apparatus in a position to engage the wheels and raise the lid vertically above a manhole of the vacuum distillation apparatus upon pivotal movement of the lid, which is initiated by nominal physical exertion of a single operator. Extending outwardly from and adjacent the manhole is a flange. The flange has a channel to receive a gasket. A protrusion extends outwardly from a bottom of the lid in a position to extend into the channel and sealably engage the gasket when the wheels disengage the tracts. Clamp assemblies are provided to releasably engage the lid with the flange and draw the protrusion into sealable, releasable engagement with the gasket.

Abstract: The invention concerns the treatment of porous structures such as cross-linked foams, woven or nonwoven, to make them electrically conductive by depositing polymers. The device enables, in a chemical reactor, to perform the activating treatment directly through non-reeled off blocks or rolls of porous structures, the treating fluids of the successive steps being made to circulate inside said blocks or rolls, via a perforated rotary mandrel whereon they are pressed. Said device enables to activate efficiently the structures, which may be metal-coated or not, and are particularly designed to be used as electrodes for liquid effluent electrolysis, of detectors and traps of organic or biological molecules, electrode supports for electrochemical generators, catalyst supports, filtering media, acoustic insulants, electromagnetic, nuclear and antistatic protection structures, heat exchangers and the like.

Abstract: The present invention is directed to an elastic laminate which is elastically extensible in at least one direction. The elastic laminate includes an elastomeric material having a first surface and a second surface opposing the first surface; and a first nonwoven layer joined to the first surface of the elastomeric material. The first nonwoven layer is formed from component fibers having a primary fiber direction. The first nonwoven layer has a Fiber Orientation Ratio within about ±20 degrees from a primary fiber direction of at least about 65%. The present invention is also directed to a disposable garment employing such an elastic laminate.

Abstract: A composite textile includes a batting layer, a cushion layer, and a face fabric. The batting layer has high melt temperature and low melt temperature fibers. The cushion layer is needled to the batting layer. The face fabric is bonded to the cushion layer by an adhesive. The face material/cushion layer/batting layer is heat set and rolled onto a roll for use in forming composite parts. The composite textile is more readily recyclable when the batting layer, the cushion layer, the adhesive, and the face material are all formed completely from material of the same chemical nature, such as polyolefin, polyester, or the like.

Abstract: A pliable pad includes a layer formed of an absorbent material and a formable material arranged generally parallel to each other. The selected formable material, such as aluminum foil, is capable of assuming a desired shape and of retaining the desired shape which has been assumed. As a result, the formable material can be shaped so that the pliable pad defines a basin for collecting and absorbing liquids. The pliable pad can also include one or more layers for defining a liquid barrier. The pliable pad can be used to collect excess liquid produced during a medical procedure, such as the irrigation of a wound, or can be used in other, non-medical applications in which liquid is to be collected.
