The present invention provides a solution to the prior art problem of producing a high density papermakers batt fabric or felt which may be secured to an undamaged under layer in an economic manner. The present invention provides these improvements by providing a batt which is comprised of a non-woven low melt scrim to which the batt material is initially needed. Subsequent to producing a batt of ...

A method of rapidly dissolving particles of water soluble polymer gels in water. A suspension of gel particles is formed and subjected to conditions of high shear in a particle size reduction apparatus whereby finely sliced particles are formed and instantly dissolve in water. Sufficient water is present that heat is dissipated and molecular degradation of the polymer is avoided.

An end component (3) is spin-welded into the cut end of an extruded tube (1) with the application of axial pressure but without the application of radial pressure to the weld area. The radial forces required to create a weld are provided by hoop stresses which are formed in the tube by shock-cooling the tube as it emerges from the extrusion die. When the tube is cut, the hoop stresses cause the cu...

A vibrating beam force transducer includes a piezoelectric beam structure supported at first and second ends, and an oscillator for inducing a vibration in the piezoelectric beam. To permit adjusting the bias frequency of the beam, an adjustment mass is formed at the center of the beam, the adjustment mass made of piezoelectric material. Part of the adjustment mass can be broken off to adjust the ...

A packing container is provided with an opening arrangement which comprises a hole (9) included in the container wall (7) and weakened areas designed and located so that the wall section between the weakened areas forms a tongue (10) projecting into the hole (9). The hole is closed by a cover strip (11) fitted over the hole and sealed to the container wall.

A fall arrest device for a pole climber which has a main yoke (30) with resiliently biased arms (34) at each end for partly encompassing a pole. The resiliently biased arms (34) are movable in the same plane as the main yoke (30) and also urge the secondary yokes into contact with the pole to accommodate a range of pole diameters. Handles are attached to each arm (34) for gripping by the pole clim...

A plate-like catalyst for reducing nitrogen oxides in flue gases in the presence of a reducing agent includes a support, an undercoating in the form of a ceramic composition disposed on the support, and a catalyst composition containing titanium oxide disposed on the undercoating.

A joint is made between elongate substrates (2,4) (such as pipes) of a conducting material by positioning a tubular insert (6) of an insulating material between the substrates, the insert having a circumferentially extending rib (8) to prevent end faces of the substrates from coming into contact. A heat-recoverable sleeve (14) is used to seal the joint. The joint of the invention provides a dielec...

A crucible for the thermal analysis of aluminum alloys is disclosed. This crucible is characterized in that the internal surface of at least one of its side walls is at least partially covered with a film of refining agent. The crucible finds application in measuring both the silicon content in and the degree of refining of hypereutectic aluminum-silicon alloys.

A pharmaceutical preparation comprising indomethacin as active anti-inflammatory drug and a metabolisable carboxylic acid and a salt of a metabolic carboxylic acid and a metabolisable carbohydrate to protect both the stomach and the intestinal tract against damage by the drug.

Process for carrying out an enzymatic reaction, in which the substrate treated is in an organic liquid which is a fluorinated hydrocarbon, which can include halogens other than fluorine.

Method for removal of asbestos fibres from buildings and equipment by penetrating the fibre compound with at least one syringe and injecting a fluid such as water containing 30-50% preferably 40% of a wetting agent, until saturation is reached. The compound together with its reinforcement and wrapping is then cut open, preferably under continuous sprinkling, and escaping air and fluids are collect...
