Inventor: HUCKINS HAROLD
IPC: B01J10/00
Filed: 1998-01-15
Abstract: Cette invention concerne un procédé et un appareil permettant de produire en toute sécurité du peroxyde d'hydrogène, ceci en injectant de minuscules bulles dispersées d'hydrogène et d'oxygène dans un milieu liquide qui s'écoule rapidement. Ces bulles minuscules sont entourées par un volume suffisant de milieu liquide pour éviter toute réaction explosive entre l'hydrogène et l'oxygène. Le milieu liquide consiste en une solution aqueuse et acide comprenant un catalyseur à base d'un métal du groupe VIII. L'hydrogène est introduit par barbotage dans le milieu qui s'écoule de manière à pouvoir s'y dissoudre, et les bulles d'oxygène entrent en réaction avec l'hydrogène dissous de manière à produire du peroxyde d'hydrogène. Le milieu liquide possède de préférence une rapidité d'écoulement d'au moins 10 pieds par seconde de manière à obtenir un régime d'écoulement bulleux dans le réacteur. Cette invention permet de combiner directement l'hydrogène et l'oxygène tout en évitant la propagation de conditions explosives à l'intérieur du réacteur. Ce procédé et cet appareil permettent de produire du peroxyde d'hydrogène en toute sécurité tout en réduisant les coûts de production.

Title: Column protector apparatus
Inventor: GUILBEAULT ROBERT H
IPC: E04C3/30
Filed: 1999-07-30
Abstract: A protector apparatus is provided for a vertical structure and includes a plurality of protector units for contacting the vertical structure, wherein each protector unit includes a structure-contacting portion, standoff portions projecting out from the structure-contacting portion, and a bumper portion supported by the standoff portions. Interconnectors are provided for connecting between the protector units for securing the protector units to each other and to the vertical structure.  The interconnectors are connected between standoff portions of adjacent protector units. The standoff portions include bolt-reception channels, and the interconnectors include double-threaded-double-ended bolts. A single threaded end of each of the double-threaded-double-ended bolts is received in a bolt-reception channel, and the interconnectors include nuts secured to the single threaded bolt ends. When the nuts are tightened on the double-threaded-double-ended bolts, the protector units are connected tightly to each other. As a result, the protector units are secured to the column by virtue of the fact that the column is in effect tightly clamped between the protector units.  In addition, the widths of the standoff portions provide a standoff distance which is greater than an outlet distance for an electrical outlet that may be located on the column. In this way, the electrical outlet is protected by the protector units.
