Microporous waterproof and moisture vapor permeable products are described which are formed from a matrix having an internal microstructure which is coated with a hydrophobic material. A process is described including the steps of (1) applying to the surface of the matrix a liquid hydrophobic material, (2) allowing the liquid to penetrate into the microstructure and then (3) drying, vulcanizing or...

Disclosed is a sanitary napkin (20) having flaps (78) folded over the topsheet (22). This arrangement helps to maintain the topsheet in a sanitary condition and is more convenient for the wearer than a configuration having the flaps folded over the backsheet. The flaps (28) may be maintained in this folded arrangement by a unitary release strip (46) which bridges the flaps and covers any adhesive ...

A stretchable nonwoven polyolefin fabric is produced by heat fusing a web of a mixed fiber containing at least 30 wt.% of a highly crimpable and heat-fusible conjugate fiber of polyolefin in such a manner that the area of each heat fusion point ranges from 0.007 to 0.8 cm<2> and the sum of the areas accounts for 10 to 40 % of the surface of the web and heat treating the web thus fused to crimp and...

An image display apparatus includes an automatic pedestal processing circuit for detecting the minimum signal level of the input video signal for controlling the signal level of the video signal on the basis of results of detection. A control section is provided for activating the automatic pedestal processing circuit during the effective display period for the input video signals to prevent ma...

Date Nov. 5, 1987.The invention relates to a method and a device for producing a mineral wool web from a thin primary web formed on a movable collecting surface (6). According to prior known methods, the primary web is folded on a receiving conveyor (18) in an ...

WASHING/DRYING METHOD AND APPARATUS A washing/drying method, comprising: dipping a material to be washed into an aqueous solution containing a surfactant having a water repellency so that at least one molecular layer of the water repellent surfactant is attached to the surface of the material to be washed; and then drying the material according to a known drying method such as vacuum drying, sha...

2081912 9117283 PCTABS00008 The present invention is an improved method for applying a dark coating (16), such as for a border, to a substrate (11) such as glass, plastic, or other transparent article. The method incorporates the use of metal carbides, oxides and nitrides, deposited on the substrate (11) by using a vacuum vapor deposition process such as a sputtering process. Other vacuum vapor de...

Pneumatic rams inside ovens have hitherto been used to thermocompression bond metal sealing components to the alpha alumina ceramic lid of a sodium sulphur cell. This invention discloses a spring loaded jig utilising disc springs. The jig comprises a pair of bayonet fastened separable portions. The components to be sealed are first loaded in the jig, compressed together and then placed in an oven.

The cathode region of a sodium sulphur cell has hitherto sometimes been sealed by a thin metal member welded at its outer periphery to the metal casing and at its inner periphery to the alpha alumina lid of the electrolyte. The welding operation damages the essential protective coating of the thin metal member. This invention discloses sealing the cathode region with a thin metal member secured to...

The adhesion between surfaces of polyimide, particularly the through hole surfaces of polyimide-based multilayer laminates used in the fabrication of multilayer printed circuits, is improved by pretreatment of the surfaces with an essentially non-alkaline aqueous permanganate solution.

The new design increases the potential density of overhead (interface) circuitry by adding extra conductor layers (16,17) which act as alignment buffers between the final metal layers (18,19) and the contact windows for the source and drain regions (33). The additional conductors are made of the same materials as those in the memory cells, and can be formed at the same stages of the fabrication ...
