Abstract: This invention refers to a sonic and/or ultrasonic generator for emission in air with a power capacity and certain radiation characteristics which permit the necessary acoustic levels (>170 dB ref. 2.10?4 ?bar) to be obtained in a way that is safe and controlled for the mechanical breakage of high consistency bubbles constituting industrial foams.

Abstract: The process consists of carrying out the first phase of generating the transaction signature (9), with prior authentication by the cardholder, in the issuing centre (3) through its authentication server (5), a second phase of decimalising (10) the signature (9) to obtain a valid permutation number and a third phase of permuting (11) the intermediary positions or digits of the card, the processor fixing a BIN and maintaining the check digit. In this way, the digits forming the expiry date are permuted. The card and expiry date are sent in the data flow (12) of the transaction to the acquiring server (7), from where they are sent back to the issuing centre (3), to its processing centre (6) to be specific, where three other operative phases are carried out: the new generation of the signature (13), its decimalisation (14) and lastly the inverse process (15) to reestablish the card's real data and expiry date.

Abstract: Starting from a purchase system wherein the holder of a mobile phone comes to an agreement with a financial company which provides him with a paycard to which he can subsequently charge his purchases, in such a manner that in each purchase he should provide his telephone number so that they may validate the operation in a processing centre contacting the user by phone to ask for the payment authorisation after identification of the user by a secret code, the invention consists of using a new card (1), with the classic sixteen digits, where the first four (2) correspond to the specific BIN of the processing company, the nine following ones (3) to the user's mobile phone number and the last digit (4) consists of a control digit for the 15 previous ones, as in any conventional paycard. In this manner, on supplying the client physically with the card, or its data through Internet, the mobile phone number is inadvertently being supplied to be able to validate the operation by telephone.

Abstract: A process and apparatus for ultrasonic cleaning of materials in which vibrating plates are used in close contact with a material to be cleaned. The material is placed in a shallow liquid and the vibrator of the plates eliminate dirt or contaminating substances from the material by cavitation of the liquid. The vibrating plates are flexurally vibrated at a frequency which correspond to its resonant frequency and is one of a sonic or ultrasonic frequency. The acoustic field created by the oscillation of the plates and in cleaning the material. A pledging system may also include ultrasonic vibrating plates to assist in expelling water.

Abstract: Apparatus for forming and cooking articles made from material of dough-like consistency. The apparatus combines: means adapted to contain a fluid cooking medium at an elevated temperature; an endless belt means adapted to continuous operation having a plurality of convex porous mold members arranged on a surface; a web-like articulated continuous conveyor means adapted to receive finite quantities of amorphous, dough-like material; and means for intermittently positioning consecutive portions of said web-like conveyor means into operative engagement with consecutive mold members to shape each of said quantities of material of amorphous, dough-like consistency into articles of desired configuration. Thereafter the engaged portions of said conveyor and belt means move into said fluid cooking medium containment means.
