Patent CA-2196477-A1 (CA)
Inventor: BONERB TIMOTHY C
IPC: E04D5/06
Filed: 1997-01-31
Abstract: A device and method for removing ice and snow from roofs whereby a flexible sleeve attached to the lower part of a roof is remotely inflated, thereby shattering the ice in a controlled and safe manner. In the preferred embodiment, a mounting frame is sealingly attached to the roof surface and is configured to removably retain the flexible, inflatable sleeve in position on the roof. A number of retention means are disclosed.  However, the preferred means is a zipper assembly, which is easy to operate and retains the overall flexibility of the inflatable sleeve to allow it to be rolled up for easy storage when it is removed from a roof. The lower end of the inflatable sleeve extends beyond the lower edge of the roof surface where it is movably secured to the edge of the roof. An operator realizing the need to remove ice from a roof remotely inflates the sleeve with a low pressure air supply. The expansion of the sleeve attached to the roof shatters the brittle ice. The movable attachment to the lower edge of the roof allows the sleeve to expand and still retains it in a taught manner when the sleeve is not inflated to prevent flapping in windy conditions.

Title: Depth stop apparatus and method for laser-assisted transmyocardial revascularization and other surgical applications
Inventor: MUELLER RICHARD L
IPC: A61B17/00
Filed: 1997-03-25
Abstract: Improved methods and apparatuses related to laser-assisted transmyocardial revascularization, and more particularly, to improved methods and apparatuses for precisely positioning a fiber-optic or other waveguide adjacent the area or areas to be lased, including at positions adjacent the posterior epicardial and endocardial surfaces of the heart and at trans-septal positions within the chambers of the heart, thereby making possible the creation of channels in myocardial tissue at precisely the positions in the heart where ischemia or infarction or other have rendered such treatment desirable or necessary. These methods and apparatuses can be adapted for use in surgical applications throughout the human body or in animals for transmitting laser energy precisely, at predetermined positions and to predetermined depths. A catheter device for performing laser-assisted transmyocardial revascularization (TMR), the device particularly adapted for delivery of laser energy via a laser delivery means or manipulation of some other apparatus inside a body cavity or organ chamber where the depth of delivery of the laser energy is critical to the procedure, the device comprising an outer lumen and a depth stop, the depth stop having a deploying means, such that when the catheter device is placed adjacent tissue to be lased and the depth stop is deployed, the spatial reference of the position of the catheter device and the laser delivery means or other apparatus used in the catheter device is maintained in a predetermined position relative to the position of the distal end of the outer lumen. Deployment of the depth stop consists of inflating a balloon tip, or there may also be an inner lumen such that deployment comprises slightly retracting the inner lumen such that an expanding mechanism such as a braided basket or "moly bolt" device increases the diameter of the end of the catheter device, thereby providing a contacting surface for performing the surgical procedure, whether it be laser ablation, visualization, or other. A method of use is also described.

Abstract: Cette invention concerne un procédé permettant d'optimiser l'utilisation d'un réseau téléphonique, lequel procédé consiste à attribuer des numéros de téléphone à un premier groupe d'utilisateurs situés dans une zone géographique, à attribuer des numéros de téléphone à un second groupe d'utilisateurs situés hors de ladite zone géographique, et à effectuer l'interconnexion de tous les utilisateurs desdits premier et second groupes par des lignes téléphoniques, de sorte que chaque utilisateur soit connecté à au moins une ligne téléphonique, ainsi que par des commutateurs. Un utilisateur peut ainsi téléphoner à un autre utilisateur en composant le numéro de ce dernier, une communication étant ainsi établie entre les deux utilisateurs. Le procédé d'amélioration fait appel à des étapes supplémentaires consistant à attribuer un autre numéro de téléphone à un premier utilisateur du premier groupe sur la ligne téléphonique existante de ce premier utilisateur, à rediriger toute communication destinée à cet autre numéro de téléphone du premier utilisateur vers un second utilisateur du second groupe en programmant une commande de renvoi automatique sur l'autre numéro de téléphone du premier utilisateur et en envoyant ainsi l'appel téléphonique vers le numéro de téléphone du second utilisateur. Il est ainsi possible de téléphoner au second utilisateur du second groupe en composant l'autre numéro de téléphone du premier utilisateur du premier groupe. Ce procédé d'amélioration comprend, de préférence, une étape complémentaire consistant à publier un répertoire contenant tous les numéros de téléphone du premier groupe d'utilisateurs du centre urbain, et dans lequel l'autre numéro de téléphone d'un premier utilisateur renvoie à un second utilisateur.

Abstract: A method of impregnating a polymer plastic plug with wood preservative. A first step involves dehydrating a polymer plastic plug to reduce its naturally occurring moisture content. A second step involves introducing liquid wood preservative into the polymer plastic plug while the polymer plastic plug is in a dehydrated state by immersing it in the liquid wood preservative and boiling the liquid wood preservative at temperatures that are less than that required to turn the polymer plastic plug into a molten state. In accordance with the teachings of this method liquid wood preservative is absorbed into the dehydrated polymer plastic plug in place of the naturally occurring moisture content.

Inventor: WAYCUILIS JOHN J
IPC: F23C6/04
Filed: 1996-11-22
Abstract: A system and process are provided for converting a light hydrocarbon gas to a synthetic heavier hydrocarbon liquid. The system includes an autothermal reformer, a Fischer-Tropsch reactor and a Brayton cycle that are structurally and functionally integrated. In the practice of the process, a mixture of a hydrocarbon feed gas, a compressed air feed and process steam is fed to the autothermal reformer to produce a synthesis gas. The synthesis gas is fed to the Fischer-Tropsch reactor where it is catalytically reacted to produce heavy hydrocarbons. The outlet from the Fischer-Tropsch reactor is separated into water, a low heating value tail gas, and the desired hydrocarbon liquid product. The water is pressurized and heated to generate process steam. The tail gas is heated and fed with compressed air and steam to the Brayton cycle having a combustor and a series of power turbines and compressors. The tail gas and air feed are burned in the combustor to produce a combustion gas that is used to drive a power turbine linked by a shaft to an air compressor, thereby driving the air compressor. The system further includes a plurality of heat exchangers that enable heat to be recovered from the outlet of the autothermal reformer. The recovered heat is used to make the process steam as well as to preheat the hydrocarbon feed gas before it is fed to the autothermal reformer, preheat the synthesis gas before it is fed to the Fischer-Tropsch reactor and preheat the tail gas before it is fed to the combustor.
