Abstract: A method and device for coupling optical fibres and opto-electronic components. In the fibre, a reflecting surface is created that is generically tilted with respect to the main propagation path of the optical radiation in the fibre, so as to originate by reflection an additional propagation path that is generically deflected with respect to the main propagation path. In a mounting support common to the fibre and the related opto-electronic component, a groove is made along an external face so as to accommodate the optical fibre in a tight condition. The groove is then covered through a laminar cover, that is transparent to the radiation and has a flat surface. The fibre is inserted into the groove in order that the deflected propagation path passes through the cover of material transparent to the radiation, and the opto-electronic component is mounted on the cover in alignment with the deflected propagation path.

Title: Intravenous fluid heating system
Inventor: SHIGEZAWA GORDON Y
IPC: H05B3/58
Filed: 2000-08-22
Granted: 2008-07-29
Abstract: A medical tubing is used for heating an intravenous fluid immediately prior to the fluid's introduction into a patient. The medical tubing comprises an internal web with a heating element along a length of the web, which heats fluid passing through the tubing. Temperature sensors at an entrance and exit of the tubing communicate the temperatures of the unheated and heated fluid, which provides a feedback control circuit for regulating the amount of heat delivered to the fluid. Current carrying wires in the web dissipate heat and thereby heat the web, which in turn heats the fluid in the tubing. A heat controlling unit adjusts an electrical current transmitted to the current carrying wires in the web. The web may be formed separately from the tubing and subsequently inserted therein, or formed integrally with the tubing by, for example, an extruding process. The web is of sufficient thickness to carry the heating element and additionally carry a separate line for the temperature signals, yet remain flexible so that the tubing can be used in the traditional manner.

Abstract: An apparatus and method for recycling drilling mud contaminated with particulates, consists of channelling a stream of contaminated slurry onto a screen deck, with the partly cleansed liquid entering a mixing tank. Liquid within the tank is continually mixed. An exit conduit removes liquid from the tank on a continuous basis, where it is given an additional purification with a cyclonic separator. The heavier fraction is further screened, with the resulting purified liquid reentering the tank. The lighter fraction exists the cyclonic separator, and a portion of the lighter liquid is withdrawn for use as a substantially cleansed liquid. Another portion of the lighter fraction is re-circulated back into the tank, thus providing multi passes through the system to provide enhanced purification. The cleansed liquid may be directed into a separate mixing apparatus, in which additional slurry-forming powder such as Bentonite is added for forming a new slurry.
