Patent CA-2212045-A1 (CA)
Inventor: POWELL JAMES ANTHONY
IPC: C02F1/68
Filed: 1996-02-01
Abstract: The invention of this application relates to a method for utilising tyres for vehicles whereby the tyres are introduced into a water such as rivers, seas, oceans or lakes, and thereby is used to improve the environment of the water and also the general environment. The method includes the step of cutting into and/or removing a portion of the rubber element of the type to expose the metal therein to the water when the tyre is submerged in the same. The exposure of the metal to the water allows the same to corrode and allows the introduction of elements of the metal into the water. This creates increased oxygenation of the water which, in turn, improves the quality, and, by photosynthesis, reduces the carbon dioxide content in the water and hence reduces the level of pollution in the same. Preferably a number of tyres are linked together to form barriers and/or reefs within the body of water and said barriers and reefs also act as a suitable habitat for marine and river life. The invention therefore provides a suitable utilisation for the vast quantity of vehicle tyres which are stored throughout the World at the present time.
Patent CA-2212250-A1 (CA)
IPC: B23K20/12
Filed: 1997-09-09
Abstract: A process and an apparatus for diffusion bonding two elements together with the assistance of instant mechanical friction is disclosed in which the areas to be joined or the whole welding assembly are heated either by localized heating methods or furnace. A constant or a variable axial pressure is applied to bring the members into contact. The bonding stress produced by the applied axial pressure, constant or variable, is maintained below the compressive yield strength of the elements throughout the entire diffusion bonding temperature range. At different stages of the bonding process, instant in-situ friction treatments at the joint are conducted by means of introducing small scale relative movement between the contact surfaces of the elements. The instant in-situ friction treatment is only aimed to reduce oxidation and to overcome the oxide barrier at the joint interface to stimulate inter-diffusion and coalescence. Microscopic mixing and localized dynamic grain growth at the joint are also achieved at the joint during friction treatment. The combination of temperature, pressure, time and instant friction applied at the contact surfaces does produce any significant macroscopic deformation of the elements. Addition of insert material at the joint interface is optional.

Title: Mill guide and anchor assembly for subterranean well casings
Inventor: WHITE PAT M
IPC: E21B23/02
Filed: 1997-12-04
Abstract: A retrievable mill guide and anchor assembly is provided for use in forming a side wall window in a vertical subterranean well casing for subsequent connection to the casing of a lateral bore liner member extending through the casing window. The mill guide extends upwardly from the top end or the anchor. With the assembly in its run-in orientation, a milling pipe with a first mill bit on its lower end is releasably locked within the upper mill guide end, and pressurized fluid within the milling pipe is used to hydraulically set the anchor in the casing. After the anchor is set, the first mill bit is rotated, lowered and deflected by the mill guide to engage and form an initial opening in the casing side wall. The milling pipe is then removed from the casing, the first mill bit is replaced with a second mill bit, and a specially designed retrieval collet is installed on the milling pipe. The milling pipe is then lowered into the casing, and the second mill bit is used in conjunction with the mill guide to enlarge the casing side wall opening to the final desired window size. The retrieval collet is then latched into the upper mill guide end and pulled up to sequentially release the anchor and pull the mill guide and anchor assembly out of the casing with the milling pipe.
