Title: A perforating gun having a plurality of charges
Inventor: PARROT ROBERT A
IPC: F42D1/045
Filed: 1995-03-28
Abstract: A perforating apparatus adapted to be disposed in a wellbore includes a plurality of shaped charges, an electrical current carrying conductor, and a plurality of exploding foil or exploding bridgewire initiators disposed, respectively, between the the plurality of charges and the current carrying conductor for simultaneously detonating thereby simultaneously detonating all of the plurality of shaped charges of the perforating apparatus in response to a current flowing in the conductor. Each of the shaped charges include a new secondary explosive primer disposed in the apex of the charge for detonating in response to a detonation of the exploding foil or exploding bridgewire initiator. The electrical conductor may include a flat cable having a plurality of such initiators spaced apart at predetermined intervals along the cable and adapted to wrap helically around the perforating apparatus until each of the initiators abut against a shaped charge of the plurality of charges in the perforating apparatus. In an alternate embodiment, the electrical current carrying conductor may include a flat sheet having a specific length and width and including a plurality of such initiators. The flat sheet is adapted to wrap around the entire circumference of the perforating apparatus until each of the initiators in the sheet abut against a shaped charge of the plurality of charges in the perforating apparatus. The current in the conductor may originate from a compressed magnetic flux (CMF) current pulse generator or from a charging capacitor of a conventional system including one or more charging capacitors and associated discharge switches. When the perforating apparatus includes a first and second perforator separated by an adaptor, the adaptor includes a pressure bulkhead adapted to seal the first perforator from the second perforator, an explosive disposed in contact against one side of the bulkhead and a piezoelectric ceramic disposed in contact against the other side of the bulkhead.

Title: Applicator for liquids such as adhesives
Inventor: GORDON FERGAL ANTHONY
IPC: B05C5/02
Filed: 1995-09-01
Abstract: An applicator is described which is sealed to a very high degree against any ingress of air and is therefore suitable for use with adhesives which react strongly with air. The applicator comprises a housing (2, 3, 4) having a bore (6) terminating at one end in an outlet aperture (10), a plunger (13, 14, 15, 16, 17, 18, 20) received in said bore (6) and mounted for movement between an open (liquid application) position and a closed position, the rear end (13, 14) of the plunger projecting from the other end (2) of the housing, the plunger including a longitudinal bore (19) for supply of liquid to be applied, the plunger being provided with one or more ports (21) through which liquid may flow from the bore (19) of the plunger into the bore (6) of the housing so arranged that when the plunger is in the fully open position the bore (6) of the housing and the bore (19) of the plunger co-operate to provide a streamlined flow path, means (16, 23, 25) for moving the plunger between the closed position and the open position; and a seal (34, 35, 36) between plunger and housing to prevent ingress of air. The novel features are (a) that the seal is a liquid barrier seal (36) and (b) that in the closed position a forward end (20) of the plunger seals said housing outlet aperture (10) and in the open position the forward end (20) of the plunger (13, 14, 15, 16, 17, 18, 20) is retracted into the housing.

Title: Magnetic resonance apparatus
Inventor: MCGINLEY JOHN V M
IPC: G01R33/385
Filed: 1995-10-11
Abstract: In a magnetic resonance apparatus whose subject receiving bore (12) is short, e.g. has an axial length to diameter ratio of less than 1.75:1, typically about 1.67:1, harmonic distortions in a temporally constant magnetic field generated in the bore by superconducting magnets (10) surrounding the bore are reduced by placing shims in shim trays (80) disposed longitudinally around the bore (12). Each shim tray contains a number of shim pockets (84) which receive ferrous shims for shimming the magnetic field in the bore. An initialization system (60) calibrates the initial magnetic field within the bore. An initial shim distribution is determined which shims the inhomogeneous magnetic field toward a target more homogeneous magnetic field. An optimization system (66) determines a residual magnetic field from a difference between the present inhomogeneous magnetic field of the bore and the target magnetic field. The amounts of ferrous material assigned to the shim pockets are optimized in fractional groups to determine optimal shim settings to produce a shimming magnetic field equal to a negative of the residual magnetic field. In this manner, the net magnetic field is made substantially equal to the target homogeneous magnetic field.

Abstract: An effective, readily ingested molluscicidal bait poison includes an inert mollusc bait and two active ingredient precursors. These precursors are edible and non-toxic to terrestrial molluscs when consumed alone. However, the composition which includes the two precursors is fatally toxic to terrestrial molluscs. One precursor is a simple iron compound, while the other precursor is selected from edetic acid, its hydroxyethyl derivatives and salts of these acids. In another embodiment a single active ingredient may replace the two precursors. This active ingredient may include ferric edetate and the ferric hydroxyethyl derivative of edetic acid.

Abstract: Un signal d'entrée alimente un comparateur qui compare ce signal d'entrée à une tension de référence VR. La sortie du comparateur est reliée à un circuit diviseur qui produit des signaux en quadrature, chacun de ces signaux ayant une fréquence égale à la moitié de la fréquence du signal d'entrée. Les deux signaux sont ensuite envoyés sur l'entrée d'un détecteur de phase qui produit un train d'impulsions corrélé à la différence de phase si ces deux signaux ne sont pas exactement déphasés de 90 DEG . Le train d'impulsions passe ensuite par un filtre passe-bas, et par un intégrateur, en vue de l'obtention d'une tension de référence ajustée VR. Cette tension VR permet l'ajustement du passage à zéro du comparateur de manière à amener les deux signaux en quadrature.
