Abstract: Apparatus for purifying confined liquids and slurries by means of a spark discharge wherein the inner surface (24) of a treatment vessel (20) is designed to include a reflector section (21) adjacent to a pair of electrodes (28) and a concentrating section (22) intensifying the shock wave generated by the discharge between the electrodes (28). An external power supply (11) is coupled through a pulse forming network (14) to the electrodes (28). The network (14) is impedance matched to the impedance of the plasma are generated between the electrodes (28) to provide a high power pulse to the electrodes (28). The establishment of the plasma produces an extremely high pressure shock wave of u.v. radiation fringing on X ray and electrohydraulic pressurization to alter the characteristics of liquid in the vessel (20).

Title: Apparatus for generating foam
Inventor: CRAWLEY HARRY D
IPC: A62C5/02
Filed: 1995-03-28
Granted: 2001-03-27
Abstract: An apparatus for generating foam includes a power source such as an internal combustion engine mounted in a frame for portable transportation of the apparatus. The power source drives an air compressor through an electric clutch which can disconnect the air compressor and a water pump. The water pump generates flow of the water under pressure through a duct system either to a water discharge valve or to a foam discharge valve. The foam is generated by injecting into the water stream a surfactant which is injected by reciprocating valve arrangement operated by flow of the water. The flow is controlled by a maximum flow orifice, a minimum flow orifice and an adjustable valve. The air compressor supplies a surge tank and the air is passed from the surge tank through a pressure regulator to a mixing device where the water and surfactant is mixed with the air to generate the foam. The mixing chamber comprises a vertical tube with a central shaft carrying a plurality of conical shaped baffles in spiral arrangement around the shaft.

Title: Ligand antagonists for treatment of breast cancer
Inventor: FUH GERMAINE
IPC: A61K38/00
Filed: 1994-02-09
Granted: 2009-12-01
Abstract: We have discovered that growth hormones form ternary complexes with their receptors in which site 1 on the hormone first binds to one molecule of receptor and then hormone site 2 then binds to another molecule of receptor, thereby producing a 1:2 complex. We believe this phenomenon is shared by other ligands having similar conformational structure. Assays based on this phenomenon are useful for identifying ligand agonists and antagonists. Sites 1 and 2 are structurally identified to facilitate generation of amino acid sequence variants of ternary complex-forming ligands. Novel variants of growth hormone, prolactin placental lactogen and other related ligands are provided. As a result of our studies with the ternary complex we have determined that selected antibodies to the receptor for these ligands are capable of acting as ligand agonists or antagonists. Novel growth hormones and novel uses for anti-growth hormone receptor antibodies are described. Methods for inhibiting the growth of breast cancer cells are also described.

Title: Loudspeaker system
Inventor: FIELD DANIEL JOHN
IPC: H04R1/28
Filed: 1994-01-27
Granted: 1999-04-06
Abstract: The present invention concerns a multiple speaker loudspeaker system wherein an internal baffle (30) extends the full length of the interior volume dividing the interior volume (24) into two unequal portions (26, 28). The baffle (30) has folded portions (34, 36), which is not parallel to the walls of the enclosure. Loudspeaker (38, 40) are mounted onto the folded portions (26, 28) within a first volume (26, 28). The loudspeaker (38, 40) radiate sound into a second volume (26, 28). One of the first and second volume (26, 28) is ported in a bandpass configuration, to the outside of the enclosure. Thus, the non-parallel portions of the baffle (34, 36) reduce unwanted peaks and/or cancellations in the sound emanating from the enclosure. Additionally, the baffle (30) is secured along its width to top and bottom walls (20, 22) of the enclosure, thus also providing extra rigidity to the enclosure.

Abstract: Un détecteur de radiations ionisantes comporte un substrat plat (30) ayant une pluralité d'arêtes parallèles découpées (40) sur une surface. Les côtés parallèles des arêtes portent une mince couche d'un matériau conducteur agissant comme une électrode (50, 60). Un faisceau (70) de particules ou de radiations à détecter arrive sur les arêtes (40) suivant une direction perpendiculaire au plan du substrat et provoque l'apparition de porteurs d'électrons/de trous dans les arêtes (40). Ceux-ci migrent vers les électrodes (50, 60) dans une direction perpendiculaire au faisceau (70), ce qui induit l'apparition de charges sur les électrodes. La lecture peut être extrêmement rapide, car les porteurs n'ont besoin de migrer que sur une courte distance vers le côté de l'arête.

Abstract: A fiber optic hydrophone is formed as a single interferometer having widely separated interferometer segments formed in each of a pair of optical fibers. The interferometer segments are designed to allow averaging of the effects of local noise sources over a broad area in order to increase the acoustic signal-to-noise ratio. The interferometer segments also allow deployment of the hydrophone around sharp bends. A first optical fiber is formed into a plurality of spatially separated outer coils. A second optical fiber is formed into a plurality of inner coils corresponding to the outer coils. The inner and outer coils are preferably arranged in concentric pairs to form a plurality of sensor segments. A plurality of spacers is arranged such that a spacer is between successive sensor segments. The spacers are formed to guide the outer and inner optical fibers between successive sensor segments such that changes in the physical parameter between the sensor segments produce no phase difference between optical signals guided by the outer and inner fibers. The outer and inner coils are preferably arranged for exposure to the parameter such that changes in the parameter at each sensor segment produce opposite phase changes between the optical signals in the outer coils and the corresponding outer coil.
