Patent CA-2244317-A1 (CA)
Title: Apparatus for performing a hydroforming operation
Inventor: MARANDO RICHARD A
IPC: B21D26/039
Filed: 1998-07-29
Abstract: A hydroforming apparatus capable of deforming relatively large and thick-walled workpieces, yet which is relatively small, simple, and inexpensive in construction and operation, includes a pressure vessel that is disposed within a frame. The pressure vessel includes upper and lower vessel members that support respective die sections therein. When the upper and lower vessel members are moved adjacent to one another, the die sections cooperate to define a die cavity in which a workpiece to be hydroformed is disposed. An inflatable bladder is disposed between one or both of the die sections and the associated upper and lower vessel members. During the hydroforming operation, pressurized fluid is introduced within the workpiece so as to expand it outwardly into conformance with the die cavity defined by the die sections. At the same time, pressurized fluid is introduced into the inflatable bladder, causing it to expand between the die sections and the associated upper and lower vessel members. The inflatable bladder allows for limited expansion of the upper and lower vessel members while preventing relative movement between the die sections. As aresult, the size, complexity, and cost of the hydroforming apparatus can be maintained at a minimum while facilitating the hydroforming of relatively large and thick-walled workpieces, such as vehicle frame components.

Title: Hartmann-type optical wavefront sensor
Inventor: DELONG RAYMOND K
IPC: G01J9/00
Filed: 1998-12-02
Abstract: An optical wavefront sensor for measuring phase tilt in two dimensions across the cross section of a beam (14), using only a single lenslet array (26) and a single camera sensor array (28). The rectangular lenslet array (26) is oriented at 45 degrees to first and second orthogonal sets of axes defining multiple points of interest (22') in the beam cross section, such that each lenslet subaperture is centered (at 40) between adjacent points of interest on the first and second axes. The points of interest (22') are locations corresponding to the positions of actuators (22) in an adaptive optics system. The camera sensor array (28) has more cells per unit area than there are subapertures per unit area. Only selected cells are activated, to provide for measurements at the approximate midpoints of lines between adjacent points of interest (22') on the first and second orthogonal axes. Thus the sensor array (28) has enough active cells to effect measurements in both orthogonal directions without interference between the cells used for measurement in the two directions, and without the need for multiple lenslet arrays or sensor arrays.

Un ensemble à brûleurs du four de réformage à combustion externe présente plusieurs brûleurs qui chauffent des tubes pour catalyse et plusieurs unités de stockage thermique qui préchauffent les flux d'air de combustion envoyés aux brûleurs. Les gaz d'échappement du four de réformage à combustion externe chauffent les deuxièmes unités de stockage de chaleur qui préchauffent les flux d'air envoyés aux deuxièmes brûleurs alors que les premiers brûleurs sont en fonctionnement et préchauffent les premières unités de stockage de chaleur qui préchauffent les flux d'air de combustion envoyés aux premiers brûleurs alors que les seconds brûleurs sont en fonctionnement. L'écoulement des gaz d'échappement est ainsi régulé de sorte que ces derniers soient envoyés sélectivement dans un premier ou un second passage. Le fluide constituant 10 à 30 % des gaz d'échappement du four de réformage à combustion externe est envoyé à un premier et à un deuxième échangeur de chaleur depuis la région à l'intérieur du four de réformage à combustion externe, et le gaz mixte d'hydrocarbures primaires bruts ou d'hydrocarbures/vapeur et l'air et/ou l'oxygène sont chauffés par les échangeurs de chaleur. Le gaz réformé généré dans le système est envoyé à un troisième échangeur de chaleur, chauffe le gaz mixte hydrocarbure/vapeur dans l'échangeur de chaleur, et sort dans un ligne de circulation de gaz réformé. Le système de réformage à la vapeur selon l'invention permet de faire des économies d'énergie élevées ou d'atteindre une efficacité de fabrication dans toute l'installation.
