Abstract: A wellbore sealing assembly including a downhole device with a sealing sleeve coupled to the uphole end. The downhole device has an internat channel allowing fluid communication through the device that is substantially blocked when a ball is seated in the sleeve. The walls of the sleeve are elastically or plastically deformable, and are shaped to be deformed when the ball is seated. When deformed, the walls are in contact with the wellbore surface substantially blocking fluid communication around the device. Elastically deformable walls of the sleeve may further include a plastically deformable layer on its inner surface that, once deformed by the seating of the ball, keep the elastically deformed walls in contact with the wellbore surface when the ball is not seated.

Abstract: In an individual section (IS) machine glassware forming system (10) that includes a gob distributor (16) for delivering glass gobs to individual machine sections (20a, 20b---20n) in sequence, blank molds (30) at each machine section for forming gobs into blanks and blow molds (32) at each machine section for forming the blanks into hollow glass containers, apparatus for timing arrival of the gobs at each machine section and terminating operation of a section in the event of an imminent gob misload comprises gob sensors (40, 42) and associated electronics (44, 46) for determining gob arrival timing at each machine section. The gob arrival timing so determined is compared to a preset shut-down limit at each machine section. Operation of the blank molds at a machine section is immediately terminated when gob arrival timing at that section exceeds the preset limit, while the blow molds and ware transfer mechanisms for that section are permitted to complete an operating cycle. In this way, damage to the blank molds and generation of tramp glass are prevented while the section is cleared of acceptable glassware. After the potentially misloaded glass is cleared and any necessary repairs are made, the machine section may be restarted employing normal restart techniques. Operation at the other machine sections continues without interruption. <IMAGE>

Filed: 1990-12-13
Abstract: Hazardous waste is formed into non-hazardous non-leaching aggregate by introducing the material to a rotary kiln where the large solids are at least partially combusted to form a primary aggregate. Gaseous combustion by-products and waste fines from the waste materials are introduced into at least one oxidizer having water-cooled metal walls. Some of the waste fines are melted to form a molten slag-like material that is removed from the apparatus and cooled to form non-hazardous aggregate. The portion of the material in the oxidizer that is not melted, is cooled, neutralized and subjected to a solid gas separation. The solid is reintroduced to the oxidizer with the primary aggregate where they are either melted or entrained within the molten material and become an integral part of the non-hazardous aggregate. <IMAGE>
