Title: Packaging for shipping compressed gas cylinders
Inventor: PIETRANTONI DENNIS P
IPC: B65D81/38
Filed: 2001-02-22
Abstract: An overpack is provided for packaging cylinders containing compressed gas.  Cylinders containing compressed gas typically have a pressure relief mechanism that releases the gas from the cylinder when the pressure inside the cylinder approaches a pressure detrimental to the cylinder. In high heat, high temperature situations such as when the overpack is exposed to a fire, the overpack of the present invention extends the time that it takes for the cylinders to trigger the pressure relief mechanism. The overpack comprises a first container (16), a second container (50) and a thermal barrier (34), which is disposed between the containers (16 and 50).

Title: Formation cutting method and system
Inventor: SHARP DAVID PAUL
IPC: E21B7/16
Filed: 2001-09-13
Abstract: A method and system for drilling or cutting a subterranean well or formation (52) using a drilling rig (5), a drill string (55), a plurality of solid material impactors (100), a drilling fluid and a drill bit (60) is disclosed.  This invention may have particular utility in drilling wells for the petroleum industry and for cutting formation in the mining and tunnel boring industries.  In a preferred embodiment, a plurality of solid material impactors are introduced into the drilling fluid and pumped through the drill string and drill bit to impact the formation ahead of the bit. At the point of impact, a substantial portion by weight of the impactors may have sufficient energy to structurally alter, excavate, and/or fracture the impacted formation. The majority by weight of the plurality of solid material impactors may have a mean diameter of at least 0.100 inches, and may structurally alter the formation to a depth of at least twice the mean diameter of the particles comprising the impacted formation. Impactor mass and/or velocity may be selected to satisfy a mass-velocity relationship in the respective impactor sufficient to structurally alter the formation. Rotational, gravitational, kinetic and/or hydraulic energy available at the bit in each of the bit, the impactors and the fluid may thereby more efficiently effect the generation and removal of formation cuttings ahead of the bit.

Abstract: A method in which information pertaining to a device (104) generating digital signatures (122) is reliably identified includes manufacturing (102) devices in a secure environment (114) and for each device (104) before it is released from the secure environment: creating a public-private key pair (116, 118);  storing the private key (116) within the device (104) for utilization in generating a digital signature (122) for a message (122); and linking the public key (118) to a Security Profile (120) of the device (104). The devices (104) then are released from the secure environment (114) and a digital signature (122) is received from somewhere (108) in the world (106). The message (122) is authenticated using a suspect public key (124) and the suspect public key (124) is compared with the linked public keys (118). A  Security Profile (120) of the genuine device (104) to which belongs the private key (116) used in generating the digital signature (122) is identified when the public key (124) matches a linked public key (118). A risk that the message (122) is fraudulently signed is determined.

Filed: 2001-09-14
Abstract: In accordance with the present invention, a pump apparatus (100) for use in conjunction with the feeding and aspiration of a patient's gastro-intestinal tract is provided. In accordance with the present invention, an apparatus (100) and method are provided in which the aspiration of excessive material and air from a patient's gastro-intestinal tract proceeds until the flow of aspirate ceases. A flow detector (130,140,142) determines when aspirate flow has ceased. Aspirate removed from the gastrointestinal tract is retained for subsequent return to the patient for absorption to prevent dehydration. After the aspiration is concluded, material aspirated from the intestine and additional nutrition or fluids are introduced into the gastro-intestinal tract for absorption by the intestine. After an optional delay to allow for the absorption of materials by the intestine, the aspiration cycle resumes. This frequent aspiration serves to prevent overfeeding and its associated risks of intestinal distention.

Abstract: Method and apparatus for adjusting the position of a cutting tool. In one embodiment, a boring tool (20) includes a coupling member (45) which is driv en by a CNC boring machine, and a sliding tool holder (35) which is slidably coupled to the coupling member. A frictional force resist sliding movement o f the cutting tool member (35). The frictional force is sufficient to retain t he position of the cutting tool during machining operations. However, the frictional force is insufficient to resist a lateral force applied parallel to the direction of sliding, as used during adjustment of the tool position. In  another embodiment, either a surface (1134) of the sliding tool holder (1135 , 1135') or a surface (1458, 1458') of a frictional member (1450, 1450') are contoured with a shape that corresponds to a desired contour of a sidewall (1184a) of a hole (1184). During machining, a follower (1457b) in contact wi th the contoured surface (1458, 1458') causes the cutting tool holder to slide laterally during machining, thus contouring the sidewall of the hole.</SDOAB >

Abstract: An integrated telephone and hearing aid that has a single in-ear speaker is disclosed. The illustrative embodiments automatically adapt the operation of the hearing aid based on whether a telephone call is in progress or not. For example, when the user is not engaged in a telephone call, the illustrative embodiments function as a normal hearing aid. But when the user does become engaged in a telephone call, the illustrative embodiments alter the hearing aid function so that the user can hear the telephone call. For example, the illustrative embodiments attenuate the hearing aid function while a call is in progress so that the user can hear both the telephone call and retain some, albeit diminished, auditory input from the environment. This enables, for example, the user to still hear loud sounds (e.g., a car horn, a fire alarm, a person screaming, etc.).
