Title: An energy amplifier for "clean" nuclear energy production driven by a particle beam accelerator
Inventor: RUBBIA CARLO
IPC: G21G1/02
Filed: 1994-07-25
Abstract: The method is for producing energy from a nuclear fuel material contained in an enclosure, through a process of breeding of a fissile element from a fertile element of the fuel material via a .beta.-precursor of said fissile element and fission of the fissile element. A high energy particle beam is directed into the enclosure for interacting with heavy nuclei contained in the enclosure so as to produce high energy neutrons. The neutrons thereby produced are multiplied in sub-critical conditions by the breeding and fission process. Said breeding and fission process is carried out inside the enclosure.

Abstract: Apparatus for providing emergency actuation of lights on a trailer is disclosed. The apparatus comprises an electrical input connector for electrically connecting the apparatus with the plug of a towing vehicle lighting pigtail, an electrical output connector for electrically connecting the apparatus with an electrical connector of a trailer lighting harness, a battery, a battery charging circuit operable to receive power from a towing vehicle through the electrical input connector and to charge the battery, and a control circuit comprising a flasher and a solenoid switch. The control circuit is operable, in a first mode, to electrically connect the towing vehicle lighting pigtail with the trailer lighting harness with a towing vehicle lighting harness and operable, in a second mode, to connect the battery of the apparatus, through the flasher, to the trailer lighting harness. The solenoid switch switches the control circuit from the first mode to the second mole when no power is delivered to the electrical input connector. The control circuit may include an actuation switch. When the apparatus is connected to the towing, vehicle lighting pigtail and actuated by the switch with the lights of the towing vehicle turned off, the apparatus will cause the trailer lights to flash until the towing vehicle lights are actuated. The trailer lights will thereafter be controlled by the lighting controls in the towing vehicle until such time as the towing vehicle lighting pigtail stops delivering power to the electrical input connector of the apparatus.

Title: Radio frequency signal reception using frequency shifting by discrete-time sub-sampling down-conversion
Inventor: WOOLEY BRUCE A
IPC: H04B1/16
Filed: 1996-06-06
Abstract: An RF communications receiver permits greater integration on standard silicon chips and consumes less power than previous receivers. Sub-sampling and discrete-time signal processing techniques are used to frequency down-convert, filter, amplify, and select a desired analog RF channel. A sample-and-hold circuit (81) sub-samples the desired analog RF channel of carrier frequency fc, thereby down-converting it to a discrete-time image signal of frequency fi. Successive down-sampling, (99. 1) anti-alias filtering, (95.1) and amplification of the discrete-time image signal yields a low-frequency discrete-time signal containing a down-converted channel of frequency fk. The low-frequency discrete-time signal is then digitized, (87) filtered, (91) and demodulated (93) to reveal its baseband information content.

Title: Personal oxygen dispenser
Inventor: PALMER KENNETH J
IPC: C01B13/02
Filed: 1996-09-09
Abstract: A lightweight, personal, portable dispenser of medically pure oxygen at appropriate temperature and delivery rate for direct inhalation is disclosed. The dispenser contains an oxygen producing generator (15) to initiate the creation of oxygen instantaneously from a fuel-less self-contained chemical reaction of extended shelf-life inert compounds in a totally safe and reliable generator. The oxygen initially enters an expansion chamber (22). A cylindrical dispenser body (1) houses the oxygen producing generator and forms an annular space between the cylindrical dispensing body and the oxygen producing generator. A bottom web (2) attached to the periphery of the bottom of the cylindrical dispenser body allows air from outside of the dispenser to enter the annular space formed between the cylindrical dispensing body and the oxygen producing generator and flow out the top of the cylindrical dispenser body. The oxygen passes through a cooling coil (25) and the air flowing through the annular space cools the cooling coil and any oxygen flowing through it. In one arrangement, the cooling coil is formed within the annular space between the cylindrical dispensing body and the oxygen producing generator and forms a cylindrical helix.
