Abstract: The present invention relates to minimally invasive surgery techniques. It provides a method for manufacturing an antenna for percutaneous acute hyperthermia microwave applications of the monopole or dipole co-axial type provided with trap, commonly called choke, for blocking the propagation of the backwards reflecting wave towards the generator. The miniaturization of the device allows a use minimally invasive for interstitial hyperthermia in medicine and surgery, in particular for oncology. The method of manufacturing the antenna provides a metal needle ( 1 ) for the introduction of the antenna ( 2,3,4 ) in the target tissue. On the external conductor ( 4 ) of the antenna ( 2 ) a metal collar 6 is connected in a predetermined position; a plastics sheath ( 5 ) is applied in order to cover the external conductor ( 2 ) in the portion between the feed ( 7 ) and the collar 6 ; the inner wall of the metal needle 1 wherein the antenna is inserted is then used for containing and guiding the collar 6 and the sheath 5 ; in particular, the collar 6 being in electrical contact with the inner wall of the metal needle 1 . An antenna is thus obtained with choke of variable length and with miniaturized diameter. A thermocouple can be introduced through the choke that protrudes the directly in the "feed" zone.

Title: Washer-polisher for fruit and vegetables
Inventor: GOMEZ SANTIAGO MARTIN
IPC: A23N12/02
Filed: 2007-02-12
Abstract: The machine has a drum (2) with several brushes/rollers (3) laid on an imaginary almost semi-cylindrical surface, with a top opening, being subjected to an alternate swinging movement / pendulum action over its axel (4). This way, the gap remaining between the brushes/rollers (3) is always upward orientated but with a different inclination in one or another direction, for which a motor or another driving element, through a proper transmission, provides the axel (4) with an angular and alternate movement of 0° to 180° or more according to the need, with the peculiarity that each brush/roller is driven independently by its own motor (5). This way the typical belts or transmission chains are eliminated, the number of brushes/rollers is less, increasing this way their operative surface, the power consumption of the machine is reduced and the rollers-brushes can revolve in the same or different direction with the possibility of changing this.

Title: Player operated win checker appended to lottery agent terminal
Inventor: MARKOWICZ VICTOR
IPC: G06Q50/34
Filed: 1994-09-26
Abstract: A wagering system such as a lottery with a central computer communicating with agent terminals at which tickets are issued, for example in convenience stores and the like, has a player-operated win-checking system coupled to the communications network, preferably as a peripheral to the agent terminal but possibly as a separate network terminal. Player choices and game identifications are bar coded on the tickets. A player scans the ticket automatically to trigger comparison of the bar coded data with winning entry data kept in a past game memory, such that the system need not resort to stored data on individual wager transactions to check for wins. This reduces the burden on the agent and the network because most issued tickets need not be checked by attempting to validate them for a payout. A limited number of past games are stored, e.g., the most recent thirty Keno game cycles of a game run at five minute intervals. One or more of the win checking system, the agent terminal and the central computer can hold the past game memory. Winning choice data is downloaded after each game, or scanned player choices are uploaded, to effect the comparison. If a ticket is too old for the corresponding game data to remain in the past game memory, the player is directed to the agent, who can use the terminal to attempt to validate the old ticket as a winner.
