An apparatus for severing (collar) blanks from a web of material is disclosed. Knife rollers (10) which are provided with knife edges (17) are used to sever blanks of (thin) cardboard from a web. A knife roller (10) is pressed against a counter roller (11). For this purpose, there are provided resiliently adjustable pressure elements (30). The pressure is exerted on the counter roller (11) in the ...

Red blood cells being salvaged are centrifuged into a liquid layer, mixed with a wash solution, and thereafter separated therefrom.

A process for manufacturing single disposable panties is described, the panties being individually separated from two continuous webs (27,26) and provided with elastic parts (4,5) at a waistline (2) and a pair of leg openings (3), the said parts being fed in continuously during manufacture and the webs being provided at predetermined points with adhesives (30a,30b), so that the elastic parts can b...

A curved edge (24) (25) (26) on a lens (21) is formed by directing a laser beam (23) onto the lens adjacent its edge and causing relative movement between the laser beam and contact lens whereby a curved surface is formed on the edge of the lens by the removal of material therefrom through ablative photodecomposition.

An antenna point at a controlled distance ahead of the centre of mass of the vehicle is caused to follow a predetermined track automatically by means of a supplementary controller (3), to which provisional signals (1 star, h star), denoting steering angle adjustment and traction or braking respectively are supplied from the main position controller (1). Outputs to respective power amplifiers (5,7)...

PURPOSE:To provide the production process which can make exact reproduction by using a mold made of a transparent resin, density of the transmitted through which corresponds exactly to the ruggedness of an original. CONSTITUTION:The original 1 consisting of wood, cloth, stone, etc., is templated by the colorless and transparent resin 2. The resin is then parted from the original to form the transp...

PURPOSE:To prevent the adhesion of a mask material or the uppermost layer component of the mask material to the rear of a supporter even when the mask material or a prepared mask material are superposed or wound and preserved by forming a blocking preventive layer on a surface on the reverse side to the light non- transmitting layer of the supporter. CONSTITUTION:In a mask material for forming a p...

A rigid duct (54) conveying the control fluid to the brake device, and a supply duct (56) receiving the control fluid from a fluid source are connected respectively to a first and a second part (46, 48) which can move with respect to each other and are connected to each other by a laminated block (40) formed by a stack of alternating metal and rubber layers adhering to one another. The end layers ...

In order to dry finely divided, expandable styrene polymers having a particle size of from 0.02 to 3 mm, the bead polymers, in the form of a slurry in water, are freed from the majority of the water and subsequently exposed to a gaseous medium. The drying is carried out in two steps, by jointly conveying the bead polymer and a first gas stream, warmed to from about 45 DEG to 120 DEG C., through ...

The invention relates to a receiver intended for receiving information transmitted from the bottom of a well to the surface, with the aid of electromagnetic waves. This receiver includes a receiving antenna (11) intended for receiving a signal transmitted from the bottom of the well; a noise detector (28) intended for detecting a noise current received by the receiving antenna; and a noise elimina...

The self-locking differential gear has a bolt (4) through a differential cage housing (1) crosswise to its pivot axle (2) from at least one differential bevel gear (5). Driven shafts (7) protrude from the housing (1) at opposite ends and have, a flanged (19) end facing the bolt (4) and supported on the housing (1) by an outer pressure bearing (20). A driven bevel gear (6) acts with axial sloping p...

A well tool such as a measuring sonde is arranged in a protective housing and introduced into a well at the end of a tubing. A retractable latching device fastens the tool to the housing and to an electrical transmission cable. The tubing is connected with a pumping assembly capable of circulating up to the housing a cooling fluid at a temperature lower than the temperature prevailing in the well ...

A cellular telephone call detail recording system records details such as number called, call duration and time of day for calculation of call billing.
