The address of each defective memory cell in a memory cell array is stored within a semiconductor ROM in advance. In parallel with the operation of reading out information from a memory cell of the array, whether or not the address of the memory cell agrees with the previously stored address of a defective memory cell is distinguished. When they agree, a correcting signal is formed. Erroneous data...

Pyrimidine derivatives of the formula in which R<1> is hydroxyl or esterified hydroxyl, and amides and Schiff's bases thereof have antiviral activity and can be used for the treatment or prophylaxis of viral, especially retroviral, infections, such as visna and HIV infections. They can be prepared starting from corresponding 3'-hydroxylated compounds.

The derivatives correspond to the formula: in which B denotes a radical derived from guanine, cytosine or adenine in which the exocyclic NH group is protected by the group with R<1> denoting a hydrogen atom or an alkyl radical and R<2> denoting a hydrogen atom, an alkyl radical, an alkoxy radical or an optionally substituted aryloxy radical, R<3> denotes a hydrogen atom, the di...

Fly waste removing system for the spinning winder which has a spinning frame and a winder connected to each other. A common cleaner having ducts is run between a spinner area and a winder area to blow off or suck the fly wastes by applying air from air injection and/or air suction ports of the ducts.

An absorbent structure is provided which contains a loosely compacted cellulosic fibrous batt having two reservoirs and a connecting channel. The absorbent structure may be an infant diaper, an adult diaper, a sanitary napkin and incontinence pad or the like.

A facing is provided for a body fluid absorbent product which facing is not only substantially nonwettable and pervious to body fluid, but which also enhances the clean and dry appearance of the product after it has absorbed body fluids. The facing comprises a polyolefin having an open area of from about 1.3 to about 35 percent of the total area intended for the passage of body fluids and having i...

Plasma albumin is separated by a crude albumin fraction from blood plasma by a rough fractional separation and then separating plasma albumin through an ultrafiltration membrane. The ultrafiltration membrane is a membrane made of a polysulfone resin having the formula (n=50 to 250).

In the treatment of the swimming pool water, the water is continuously withdrawn from the pool and brought into contact with semi-permeable membranes of a separating apparatus. The fraction of the water which has passed through the membranes is returned to the pool.

The perfumed tampon is made up of an ultrathin polyurethane membrane 40 in which a perfume is dispersed. A layer of pressure-sensitive adhesive 41 is applied to make the element adhere to a surface. The polyurethane is made from a diisocyanate, a macroglycol and an acrylic chain terminator, a photoinitiator and a perfumed oil being added thereto before the curing. A layer forming a barrier 43 may ...

The invention applies in particular in cards containing CCC-type components for electronic payment or security cards. A continuous conducting strip is made up, on which is grafted a series of conducting cells (29, 30) made up of a part with contacts (C1-C8) and of a central region (S1) on which will be deposited a microcircuit. Then, a protective resin capsule (31) will be deposited on the face ca...

The invention relates to a foldable articulated cloth, without permanent fold, and a blind manufactured with this cloth. The articulated cloth of the present invention is continuously manufactured by weaving warp threads and weft threads made from any materials, such as textile fibres or metallic threads. In its structure, the articulated cloth has at least one longitudinal zone of weakness formin...

In previous composite building slabs for sectional false floors, which are supported at their four corners and consist of an upwardly open trough produced from tension-proof material and of a filling of compression-proof material, e.g. anhydrite, a greater deflection is produced, under load, at the edge of the slab than in the centre of the slab, which is undesirable. In order substantially to eve...
