An apparatus for controlling the level of liquid in a centrifugal separator drum by regulating the flow of liquid out of the drum. The drum includes a plurality of circumferentially spaced openings in a radial end wall of the drum. The openings have movable weir plates in one form controlling the openings with the weir plates movable and positionable in a radial direction by axially movable linkag...

Here is disclosed a method for manufacturing individual disposable underpants provided around a waist line and a pair of leg-holes with elastic members from two continuous webs and a plurality of continuous elastic members, characterized by that the webs are applied on predetermined locations with adhesive so that the elastic members can be reliably held on the webs although the elastic members mu...

A biaxially-oriented film with high mechanical strength, which includes 69 to 94.99% by weight of a polyolefin, 5 to 30% by weight of a natural or synthetic resin having a softening point in the range from 70 DEG to 170 DEG C., and 0.01 to 1% by weight of a nucleating agent, based on the total weight of the film. A method for producing this film includes biaxially drawing the film at temperature...

INSPECTION APPARATUS FOR TUBULAR MEMBERS An inspection apparatus for the internal inspection of tubular members has a body 1 adapted for insertion into the tubular member and the body has an inspection window 2. A projection means including a laser 14 and associated reflectives 13, 10 and 9, the reflective 9 being rotated by a motor 7, is directed such that a beam of radiant energy is directed thr...

The invention relates to a high density composite sheet based on discontinuous mineral fibers. The inventive sheet has a content of mineral fibers greater than 70 wt. % of the total weight of fibers and binder, and has a density between 400 and 1600 kg/m3. The sheet can be employed in particular as an architectural structural wall facing, as a component of a composite insulating panel, etc., and i...

A method of molding and coating in a mold a thermosetting substrate includng the steps of forming the substrate between at least two separable dies which form a mold cavity therebetween, curing the substrate to the point that the substrate is receptive to a coating, injecting the coating into the mold cavity at a pressure substantially in excess of the mold cavity pressure while maintaining the di...

A polynucleotide which has been modified by a hydrophobic moiety so that the polynucleotide attaches to a substrate by the hydrophobic moiety, rather than by a portion of the polynucleotide, thereby allowing the polynucleotide to be available for hybridization.

A container for enclosing a liquified gas tank protects the tank from rough handling and prevents the corrosion from exposure to the atmosphere. The container comprises a vertical cylindrical shell with bottom cap attached thereto, formed of resilient plastic non-combustible material, the inside diameter of the shell being greater than the outside diameter of the gas tank; removable friction fit l...

In the continuous production of mineral wool nonwoven fabrics, fiber/gas/air mixtures (3, 4) produced by several shredding units (14 to 17) are directed onto collecting conveyor units (19, 21) with suction surfaces (c, d) running in a curve and being under suction pressure for the formation of a wool nonwoven fabric (25). In this case the arrangement is such that an imaginary suction surface, incr...

Mutant enzyme having reduced stability under industrial application conditions A mutant enzyme is provided which exhibits reduced stability under industrial application conditions. As an example mutant bacterial .alpha.-amylase is provided which has reduced thermostability during baking conditions. This modified .alpha.amylase can be suitably used for improving both loaf volume and crumb softness ...
