Abstract: The present invention relates to an apparatus for protecting and insulating an electrical connection in a hazardous area adjacent a wellhead barrier of a well enclosing fluids.  The electrical connection is between a first electrical conductor extending from a non-hazardous area and a second electrical conductor extending through the wellhead barrier.  The second electrical conductor includes a conductive portion circumscribed by insulation.  The apparatus is comprised of a unit for electrically and mechanically coupling the first and second electrical conductors together forming the electrical connection.  A breather boot is provided for protecting and insulating the electrical connection.  The breather boot includes an inner cavity for containing the electrical coupling unit, a first opening for receiving the first electrical conductor and a second opening for receiving the second electrical conductor. The insulation is terminated  within the breather boot.  A header space is located where the insulation is terminated within the second opening.  A gas block seal passage is provided adjacent the header space allowing passage of the conductive portion of the second electrical conductor from the second opening to the electrical coupling unit.  A breather passage is provided which allows fluid communication between the header space and the area surrounding the breather boot.  The breather passage and the header space are filled with a dielectric compound so that in the event well fluids escape between the insulation and conductive portion of the second electrical conductor the well fluids will escape without migrating through the gas block seal passage.

Title: Remedies for eating disorders
Inventor: HASHIZUME KIYOSHI
IPC: A61K38/27
Filed: 1997-07-02
Abstract: Remedies for abnormalities in eating attitudes caused by anorexia nervosa. Although it has been a practice to use tranquilizers, etc. for treating mental symptoms characteristic of anorexia nervosa typified by abnormalities in eating attitudes, such as refusal of food, intentional vomiting and eating in secret, only poor effects can be achieved thereby. The administration of the above-mentioned remedies, i.e., human growth hormone (hGH) preparations makes it possible to impart the spontaneous will to eat to those who can get nourishment exclusively by passive means such as compulsory nutritional education or nasal feeding. These remedies are particularly efficacious against eating disturbance of anorexia nervosa seemingly based on the hypersecretion in the central growth hormone releasing factor (GRH)-hGH secretion system.

Title: Roll on - roll off piggyback bimodal terminal system
Inventor: KLEIN DONALD R
IPC: B61B1/02
Filed: 1999-03-08
Abstract: The invention is a system for transporting highway vehicles on railway vehicles. It has rail cars positionable relative to one another at an angle of at least about 50 degrees. Each car has a deck for highway vehicles. The system has a railroad terminal with a first track with switch(es) connected to spur(s) so trucks supporting a first set of car ends may be kept on the first track, while a second set of trucks supporting a second set of car ends is placed on the spur(s). The rail cars are thereby placed in a zig-zag configuration. For each of the rail cars, a truck supporting one end remains on the first track while a truck supporting the other end is placed on a spur. A vector parallel to the direction of travel of a truck along the tracks supporting it has a vector component of at least about 0.25 in a direction parallel to the centerline of a railway vehicle supported on the truck, so forces for moving rail cars into and out of the zig-zag configuration may be communicated by tension or compression along the rail cars. The terminal has a dock or ramp having an elevation about equal to the elevation of the rail cars so that highway vehicles may be driven or pulled onto or off the rail cars. The terminal has a roadway or other driveable path to an external highway system.
