In digital transmission systems, adapted data units travel at a high throughput rate over large parts as a stream of fixed length data packets, called cells in this instance. The present method permits the measurement of characteristic magnitudes of the cell stream with respect to the respective individual connection to which they belong. It is based on storing from each arriving cell the identifi...

Material that is to be used in wrapping medical items or in making gowns, drapes, and the like is treated with silicone to make it liquid repellent. The material, after being sterilized by an oxidizing plasma process, still retains its repellency.

In a contact-type vapor and particle sampling apparatus for collecting vapor or particles from a moving subject, a wand having a plurality of sampling holes is oriented so that the holes extend in the direction of movement of the subject. The external width of the wand is less than a characteristic dimension of the contour of the surface of the subject being sampled, and a central fluid flow passa...

A clothes washing-drying machine provided with a washing tub (1), a drum (2) which rotates within the tub and which is capable of containing the articles to be washed and rotating at different speeds including the spin speed, a discharge conduit (5) disposed below said tub, a circuit for circulating the drying air which is made up at least by a first conduit (6) for drawing in moist air from the i...

A center star assembly for use with a capping machine where the center star assembly can be quickly removed from the capping machine and replaced with another center star assembly for handling different size bottles or containers without having to remove and reinstall any fasteners or other mounting components.

The method consists in forming a product of coagulated polyurethane, immovably bound to a flexible support, and stripping the product from the support only when all the operations of forming of the product itself have been completed, so that said operations can be carried out by methods independent of the strength of the product. The layout comprising at least one station for spreading polyurethan...

Dredging apparatus for bottoms in which the boxlike body of the dredging head has side pieces completely closed and watertight and it is provided with at least one opening through which a volumetric pump, actuated by a variable-speed and controlled motor, can admit into said body the necessary water for fluidification and transport of the dredged material, which water is aspirated from the surroun...

A machine tool for machining panels, plates and discs, is fitted with a number of workpiece clamping devices (10) that move along a work bench (20) of the machine tool. The machine tool has sensors (8) designed to detect the position of the clamping devices (10), and a unit (2) built into the operating head (15) of the machine tool, which engages the clamping devices (10) to move them to preset po...

A biscuit is described which is free from added fats and includes from 36 to 90% by weight of cereal flakes and from 7 to 28% by weight of sugar binder. The biscuit is manufactured by baking and extrusion of selected ground cereals and flaking and mixing of the flakes with the sugar binder. The flake-binder dough, which is obtained with a moisture content of 15-30%, is finally shaped.
