Title: Cartouche pour outils industriels a detonation
Inventor: SCHINDLER JOHN J
IPC: F42B5/26
Filed: 1995-03-03
Granted: 2005-08-09
Abstract: La présente invention concerne une cartouche (24) pour outils industriels à détonation (10). Ce type d'outil comporte un pointeau perforateur (46) qui perce une surface de la cartouche pendant le montage de la cartouche dans l'outil. Lors la mise à feu de la cartouche, les gaz résiduels produits par l'explosion sont évacués dans l'atmosphère après que le pointeau perforateur se soit dégagé de la perforation. Sur une surface de sa base (62), la cartouche de la présente invention comporte un creux (64) dans l'alignement du pointeau perforateur (46). Une section (66) relativement mince de la base reste au fond du creux. Cette section fine est dimensionnée de sorte que lorsqu'elle n'est pas soutenue, par exemple lorsque l'on utilise un pointeau perforateur défectueux, elle se fracture sous les forces dégagées par la poudre en explosant et que les gaz résiduels produits par l'explosion soient évacués dans l'atmosphère par cette fracture.

Title: Method for stripping open ended bellows part from injection mold
Inventor: ODER REUBEN EARL
IPC: B29C45/43
Filed: 1995-10-27
Granted: 2001-04-17
Abstract: A method for stripping an open ended bellows part from an injection mold has as a first step the injection molding of a bellows part. The bellows part has a resilient portion located between a core pin (28) and a first split cavity (30) and a substantially rigid portion located between the core pin (28) and a second cavity (44). The substantially rigid portion has a first open end (46) and an external undercut portion (48), and the resilient portion of the bellows part has an inner surface and a second open end (50). The first split cavity (30) opens laterally to permit the resilient portion of the bellows part to be stripped from the core pin (28). Compressed gas passes through the core pin (28) to the inner surface of the resilient portion of the bellows part while both open ends of the bellows part are closed off by the second cavity (44) and the core pin (28). As the cavity and core portions of the mold separate, the second cavity (44) grips the undercut portion (48) of the substantially rigid portion of the bellows part, thereby pulling the resilient portion of the bellows from the core pin (28) while compressed gas maintains the resilient portion expanded. Finally, the second cavity (44) either opens or has a stripper rod (54) to disengage the undercut portion (48) of the substantially rigid portion of the bellows part so that the bellows part may be ejected from the injection mold.

Abstract: An expendable autonomous underwater vehicle (10) is deployed from a trash disposal unit (32) of a submarine (30) into a body of water. The vehicle (10) and one or more launch-aiding components (44, 46, 51, 52, 60, 72) are inserted into the trash disposal (32) in an arrangement that results in safe and reliable deployment from the trash disposal unit. The launch-aiding components keep the vehicle in a predetermined orientation within the trash disposal unit prior to deployment and protect the trash disposal unit from damage. The launch-aiding components also aid the vehicle in ejecting from the trash disposal unit and descending into the body of water to a depth at which the vehicle can begin its autonomous operation. In general, the vehicle must be a safe distance away from the submarine before it begins operation. The launch-aiding components fall away from the vehicle in the body of water as the vehicle descends thereinto. The expendable autonomous underwater vehicle, which is typically used by submarine personnel as a training target, drops to the bottom of the body of water after its internal battery is exhausted.

Abstract: Techniques for patterning chemically or biochemically active agents on a substrate surface involve providing a micromold having a contoured surface including indentations defining a pattern and forming, on a substrate surface, a chemically or biochemically active agent or fluid precursor of a structure on the surface. A chemically or biochemically active agent or fluid precursor also can be transferred from indentations in an applicator to a substrate surface. The substrate surface can be planar or non-planar.      Fluid precursors of polymeric structures, inorganic ceramics and salts, and the like can be employed to form patterned polymeric articles, inorganic salts and ceramics, etc. at the surface. The articles, according to one aspect, are formed in a pattern including a portion having a lateral dimension of less than about 1 millimeter. Smaller dimensions can be achieved. The indentation pattern of the applicator can be used to transfer separate, distinct chemically or biochemically active agents or fluid precursors to separate, isolated regions of a substrate surface. The invention provides for inexpensive and simple synthesis of a combinatorial chemical or biochemical library.

Abstract: A new peptide, k-conotoxin PVIIA, is disclosed. This peptide is found naturally in the cone snail Conus purpurascens and has the amino acid sequence Cys-Arg-Ile-Xaa-Asn-Gln-Lys-Cys-Phe-Gln-His-Leu-Asp-Asp-Cys-Cys-Ser-Arg-Lys-Cys-Asn-Arg-Phe-Asn-Lys-Cys-Val (SEQ ID NO: 1) where Xaa represents 4-trans-hydroxyproline, hydroxyproline or proline. This peptide together with a previously disclosed peptide, 6-conotoxin PVIA, act synergistically to rapidly immobilize fish which are injected with the two peptides. Injection of r.-conotoxin PVIIA alone results in different symptoms with an injected fish becoming hyperactive and then contracting and suddenly extending all major fins. This "fin-popping" occurs repeatedly resulting in a series of jerky movements, but injection of only k-conotoxin PVIIA does not immobilize or kill the fish.

Granted: 2005-07-05
Abstract: A human body detector for a seat which does not deteriorate comfort of sitting even when it is disposed on the seat, has a high sensitivity and can be easily fitted to the seat. Vibration detection means (5) is disposed in such a manner that even when a person is seated, the means (5) comes into contact with the bottom surface of a seat pad (16) of a seat (19) and accordingly the person does not feel the means (5). According to this construction, the human body does not easily feel the means (5) by the provision of the seat pad (16), the existence of the vibration detection means (5) is hardly felt even when the hardness and the shape are changed, and various measures for improving the sensitivity of the vibration detection means (5) can be taken. The vibration detection means (5) may be merely bonded to the seat pad (16) or may be fixed to a seat spring (17) or a seat frame (18), and can be fitted more easily to the seat (19) than when it is disposed below a surface cloth (15) of the seat (19).

IPC: H04Q3/00
Filed: 1997-10-14
Granted: 2004-02-24
Abstract: A method of controlling traffic in an intelligent communications network having a distributed processing environment using software objects corresponding to respective components of the network, wherein each object is associated with a respective service element parameter (SEP) and writes its SEP to a SEP field of each generated request, together with, in the event that the request is generated in response to receipt at the object of a request sent from another object, the contents of the SEP field of the received request. While an object is in overload state it rejects newly received requests if the contents of their S EP fields are less than a threshold. If the object is already handling a request, a newly received request will take priority if it has a higher SE P value. The request which gives way may be rejected, or may have its processing suspended.

Title: Arc fault detector comparing integrated interval to interval filtered load current and circuit breaker incorporating same
Inventor: SCHMALZ STEVEN CHRISTOPHER
IPC: H02H1/00
Filed: 1999-06-02
Granted: 2011-04-26
Abstract: Arc faults are detected by bandpass filtering the current to generate a sensed current signal with a pulse each time an arc is struck. A resettable integrator integrates this sensed current repetitively over equal time intervals such as each cycle of the ac current. The integrated value of the sensed current is compared with the value for the previous corresponding time interval stored in a sample and hold circuit, with the indications of interval to interval increases and decreases in the integrated sensed values for a selected number, such as six, of the most recent time intervals stored in a shift register. For each time interval, a chaos detector counts the number of changes between increases and decreases for the selected number of most recent corresponding time intervals and accumulates a weighted sum of the counts which is time attenuated. When the sum reaches a predetermined amount, an output such as a trip signal for a circuit breaker is generated.
