Title: Luggage safety barrier
Inventor: COOGAN JAMES DEANE
IPC: B60R21/12
Filed: 1995-08-31
Abstract: A safety screen or barrier (10) for the protection of occupants within the vehicle against unrestrained forwardly moving loads within the vehicle in a situation where the vehicle suddenly decelerates.

Patent CA-2187432-A1 (CA)
Title: Production wells having permanent downhole formation evaluation sensors
Inventor: TUBEL PAULO S
IPC: E21B47/10
Filed: 1996-02-09
Abstract: A downhole control system for a production well is associated with perma-nent downhole formation evaluation sensors which remain downhole throughout production operations. These formation evaluation sensors may include, for exam-ple, neutron generator, gamma ray detector and resistivity sensors which can, inreal time, sense and evaluate formation parameters including important information regarding formation invading water entering the producing zone. Significantly, this information can be obtained prior to the water actually entering the producing geo-logical formation and therefore corrective action (i.e., closing of a valve or sliding sleeve) can be taken prior to water being produced. This real time acquisition of formation data in the production well constitutes an important advance over current wireline techniques in that the present invention is far less costly and can anticipate and react to potential problems before they occur. In addition, the formation eval-uation sensors themselves can be placed much closer to the actual formation a.e.adjacent the casting or downhole completion tool) than wireline devices which are restricted to the interior of the production tubing.

Abstract: Les appareils servant à empêcher la formation de glace dans les ouvertures pratiquées pour fins de pêche sur glace qui existent actuellement sont très utiles mais apportent beaucoup de désagréments aux pêcheurs lors de leur utilisation. Ainsi, plusieurs de ces appareils sont munis de composantes chauffantes ou de ballons gonflés lesquels sont insérés dans le trou et doivent être retirés dudit trou à chaque pêche.      D'autres appareils ne font que protéger la surface du trou en étant disposés sur la surface de la glace. Enfin, certains appareils gèlent au niveau de leur extrémité supérieure et ce, étant donné sa position trop près du niveau de l'eau. Ainsi, la présente invention remédie à ces inconvénients par sa simplicité d'utilisation en minimisant le déplacement d'air refroidissant l'eau et donc, permet à l'appareil de demeurer dans le trou pour toute la journée de pêche.

Inventor: SCHABEL GREGG W
IPC: F16D3/40
Filed: 1997-06-02
Abstract: An improved driveshaft assembly includes a cylindrically shaped driveshaft tube and a tube yoke. The tube yoke is attached to the driveshaft tube and transfers torque between the driveshaft tube and a universal joint. The tube yoke has a first end having a tube seat for connecting the driveshaft tube to the tube yoke and a second end having lugs for connecting the tube yoke to the universal joint. The tube seat has an outer surface which is fixed to the driveshaft tube to prevent relative movement between the driveshaft tube and the tube yoke. A diamond-shaped relief formed in an end surface of the tube seat has two pairs of opposed points, with each point positioned 90 degrees from another point. Flats are foamed between each adjacent points. The diamond-shaped relief is oriented to provide tube seat walls which are thickest at the locations which receive the greatest stress during rotation of the driveshaft assembly. Two of the points face the yoke lugs and the other two face at 90 degree angles away from the yoke lugs. The diamond-shaped relief reduces the weight of the tube yoke and prevents undesirable distortion of the tube seat which can weaken the union between the tube yoke and driveshaft tube.
