Equipment for the preparation of electric conducting composite samples by infiltration in a mould characterized in that it essentially comprises: - a pressurization/infiltration chamber having at least one opening to connect it by means of appropriate tubes with a vacuum line and a pressure line and devices for sealing both under vacuum and under pressure; - a sample-holder, inside said chamber, m...

A technique for regulation of packet switched network traffic through usage-sensitive pricing is disclosed. The network is partitioned into logical channels and a user incurs a cost for use of each of the logical channels. The logical channels differ primarily with respect to the cost to the user. Each user will select a channel that provides the subjectively optimal balance of cost and perceived ...

An apparatus for collecting particulates and vapours from a contaminated surface includes a manifold having at least one nozzle receiving gas from a supply and directing at least one jet of gas onto a target area of the surface thereby to dislodge particulates and vapours from the surface. The manifold also has an orifice therein, one end of which is adjacent the target area. A pump draws gas and ...

The plasma torch is provided with means allowing at least one electrode to be installed. It incorporates an inner hollow space which extends close to the distal end (22) of the electrode (2). Coolant is delivered by means of a pipe element arranged coaxially to the electrode. The pipe element (3) extends in the inner space (21) towards the inner section (20) of the distal end (22) in such a way ...

A cigarette portion (2) is transferred from a bed (5) of a manufacturing machine (1) to a respective first seat (51; 52) of a supply unit (12) for supplying an input conveyor (8) of a filter-assembly machine (3) by means of a pickup member (28) having a second seat (37) for receiving and retaining the cigarette portion (2) and movable along an annular path (T) tangent to the bed (5) and to the sup...

A method of rolling cigarette portions (16a, 16b, 16c, 16d), wherein a first succession (B) of first pairs (19) of cigarette portions (16c, 16a) and a second succession (C) of second pairs (20) of cigarette portions (16b, 16d) are advanced in a direction (D) crosswise to the respective axes of the cigarette portions (16a, 16b, 16c, 16d), each first pair (19) being defined by a first and a second c...

A method of conveying bar-shaped articles (1a, 1b, 16a, 16b, 16c, 16d, 21, 22, 23) on a filter-assembly machine, wherein first articles (1a, 1b) arranged in an orderly single succession (A) are advanced crosswise with respect to a given traveling direction (D); the first articles (1a, 1b) are cut in half in a direction parallel to the traveling direction to form second articles (16a, 16b, 16c, 16d...

L'invention concerne des dispositifs (monocanal et multicanaux) de démodulation cohérente. Selon l'invention, la démodulation cohérente est effectuée sans aucun e connaissance du signal transmis (c'est-à-dire sans pilote). L'estimation du déph asage est obtenue en produisant grâce à l'application d'une fonction prédéterminée, une va leur signée à partir de l'argument d'un signal sommé, ce signal s...

A cover for the cargo area of a vehicle includes two rails secured to opposite sides of the cargo area of the vehicle. A cover material is bounded by four peripheral rails. Two of the rails have the same cross-section and are located on two sides of the cover material. The other two rails are of a different configuration and are located on other two sides of the cover. A biasing member, such as a-...

Crossways-orientated to the first and second rails (51,52) are several components (8) supported on a base. The first and second rails are foxed to each other end to end by coupling devices (41,42). The components (8) supporting against an unprepared base (6') are formed at one end with a coupling device (8a). - The coupling device is suitable for a firm but easily removable cooperation with facing...

DETAILED DESCRIPTION - A guard (1) covering the front of the switches is joined to a cover part (2) running parallel to the top of the cooker. Attached to either side of the cover part are a pair of wings (3) with heels (4) protruding from them that slot into openings (7) in plates (5) mounted on opposite sides of the hob when the guard is lowered into position to protect the switches. The guard c...

To provide an apparatus for generating pseudo-random numbers at a high speed with sufficient cryptographical security, the apparatus comprises: a T-ary counter (101) for generating a count number from 0 to T ~ 1 cyclically by incrementing the count number in synchronization with a clock signal; a modulus memory (103) for outputting a prime number read out from T prime numbers prepared therein acco...
