The intermediate enclosure member is attached to a first trippable coupling member (146) which when trippe...

Disposable absorbent article such as a feminine hygiene pad, an adult incontinence article or a baby diaper having a minimised tendency for creating negative skin occlusion which might create over-hydration of the skin by exhibiting a low Breathability Value as impacted by the vapour permeability of backsheet materials and the respective areas as covered by such materials.

An object to be imaged is positioned between an x-ray source and an x-ray imager. The x-ray source is operated to direct x-rays through and around the object. Electrical signals representative of the intensity of the x-rays impinging on the x-ray imager are used to locate a boundary of the object, and an x-ray image is generated using this boundary. Alternatively or additionally, an x-ray image is...

The shoes (10) and models (50) are reusable and have standard shoe split diameters and chord lengths to reduce the time necessary to make th...

Rigid polyurethane foams having a low thermal conductivity are produced by reacting a) organic and/or modified organic polyisocyanates with b) at least one compound containing at least 2 reactive hydrogen atoms in the presence of c) blowing agents, d) catalysts and, if desired, e) auxiliaries and/or additives, wherein graphite is added to the component a) and/or b).

Method for inspecting an article for defects, light scattered by the article is collected. A defect in the article gives rise to a pulse scanning response signal, which is fed to a processing unit. The light beam has a wavelength such that the article is transparent thereto. At least two scanning response signals are obtained, which are associated with focal points at different focal depths in the...

A method for determining the relationship between the heading of a machine and the course of machine travel is provided. The method includes the steps of determining a previous and current course of machine travel, and a current and filtered heading. An indicator is used to represent the relationship between the heading of the machine and the course of machine travel. The previous and current cour...

Plastic pipes made of unsaturated polyester resins have low-molecular polyester units with free hydroxyl groups. These functional groups, which are present in the inner lining that is rich in resin, form the inner wall of the pipes and act as centers for chemical reactions involving various compounds such as water, inorganic and organic acids, and oxidation agents. When polyester tubes are used in...

A piston for operation of a hydraulic brake produced in a cold-forming process, for example a deep-drawing process, has a relatively thin outer wall (4) which has a cross-section smaller than the desired contact surface (A) for the contact of the piston (1) with the brake lining. According to the invention, it is proposed to roll the edge (3) of the pot-shaped piston (1) inwards and then to machin...

A method is disclosed for recycling fused vinyl plastisols. The vinyl plastisols are comminuted and dissolved in a solvent, such as cyclohexanone, dichloromethane, hexane, chloroform, methyl ethyl ketone or ethyl acetate. A plasticizer is added to the solvent mixture after the vinyl plastisol has dissolved, and the solvent is removed from the mixture under vacuum.

The monitoring method includes the steps of: acquiring a signal (s(t)) from an acceleration sensor; calculating a transform in the frequency domain of the signal (s(t)) to obtain a sequence of samples; acquiring a sample (F(2)) in the sequence of samples; calculating an actual amplitude value (C2) of the acquired sample (F(2)); calculating a relative deviation (RC2) between the actual amplitude va...

The monitoring method includes the steps of: acquiring a first signal (s(t)) from an acceleration sensor; calculating a transform in the frequency domain of the first signal (s(t)) to obtain an initial sequence of samples (S1), each of the samples having a respective amplitude and a respective frequency; processing the initial sequence of samples (S1) to obtain a final sequence of samples (S3); ca...
