Title: Tuyere for installation in hearth of electric arc furnaces
Inventor: DUDILL ROGER
IPC: F27B3/22
Filed: 1992-12-07
Abstract: ABSTRACT            TUYUERE FOR INSTALLATION IN HEARTH OF          ELECTRIC ARC FURNACE      Molten metal in an electric arc furnace is stirred by introducing a gas into the melt through tuyeres mounted in the hearth. Each tuyere has an inlet portion having a passage of relatively large diameter and an outlet portion having a passage of relatively small diameter. The tuyere is mounted in the bottom of the electric arc furnace with the inlet portion extending through the furnace shell and part of the reractory brickwork. With this design of tuyere gas at convenient-ly available pressure (16 bar A) can be fed to the tuyere and leaves the outlet portion at least at sonic velocity thus forming a relatively stable jet which inhibits molten metal entering the tuyere. The outlet portion may have a first portion with a slightly larger internal diameter than a second portion downstream of the first portion. When the second portion is fully eroded the flow of gas increases and triggers an alarm. However, the internal diameter of the first portion is still at least sonic to inhibit the ingress of molten metal into the tuyere.             * * *     (Figure 2)
Patent CA-2084849-A1 (CA)
Inventor: ADOLPHI JOHN
IPC: G03B15/10
Filed: 1992-12-08
Abstract: A special effects carrier for use in a photographic camera for taking portraits of individuals or groups. The wheel-shaped special effects carrier contains masks which produce various special effects. One of the masks included on the carrier produces no special effects so that the carrier can be used whether or not a special effect is desired. The carrier is located a fixed distance behind the objective element of the zoom lens so that the photographer is able to focus the camera without having to compensate for the changing focal length of the zoom lens. The carrier is connected to a CPU which drives a motor to rotate the carrier. An optical sensor reads bar codes on the carrier and relays information to the CPU thereby allowing the CPU to position the masks for use and freeing the photographer of that task.

Patent CA-2094302-A1 (CA)
Title: Ozone generation apparatus
Inventor: WEAVER WILLIAM C
IPC: C01B13/11
Filed: 1993-04-19
Abstract: Abstract of the Disclosure Ozone generating apparatus designed for installation into airflow ducts or other air handling structures of housing units or other buildings includes a porous gridwork, mesh, or other minimal airflow obstruction support with an ozone generating plate positioned to release ozone into passing air.  A second housing attached adjacent to the first housing contains electrical circuits for developing an electrical potential applied across the ozone generating plates positioned in the first housing. The second housing has a control surface that includes a control mechanism for controlling the electrical circuits.  The second housing also accommodates a first switch for activating and deactivating the electrical circuits that generate an electrical potential across the ozone generating plates.  A rocker sail, positioned adjacent to the first switch and pivotally attached to one of the first and second housings for pivotal movement, causes activation or deactivation of the first switch in response to airflow through the first housing.  Air striking the rocker sail pivotally moves the sail, activating the first switch, and consequently generating ozone.  In the absence of airflow, the rocker sail is biased to return to a position that deactivates the first switch.  Accordingly, when airflow ceases the rocker sail moves to a position that deactivates the first switch, causing the generation of ozone to cease.

Title: Method and apparatus for converting non-recyclable waste into a useable product
Inventor: PREIKSCHAS RONALD D
IPC: B29B17/02
Filed: 1993-09-01
Abstract: ABSTRACT   A method and apparatus for converting solid, typically considered non-recyclable waste into a useable product is disclosed. In one embodiment, the apparatus includes a pre-sizer to receive non-recyclable waste from a surge hopper and reduce the waste to particles of a first particle sizer. From the pre-sizer, the particles are conveyed to a final sizer 16 wherein they are reduced to particles of a second particle size smaller than the first particle size. From the final sizer, the particles are conveyed to a first separator in the form of a mechanical vibratory screener. Between the final sizer and the separator are located two additional separators designed to remove metal, rubber and/or vinyl material from the particles. The first separator screens the particles and has three or more outlets, at least one outlet for oversized particles, at least oneoutlet for undersized particles and at least one outlet for particles of the desired sizer. The outlet for the oversized particles leads to a feedback conveyor system which runs back to the inlet of the final sizer. The outlets for the desired andundersized particles lead to respective storage chambers.

Abstract: An electrosurgical unit (10) which combines an electrosurgical power generator and a filtered smoke removal system into a single compact instrument comprising an electrosurgical generator module (12) and a smoke removal module (14).  The electros-urgical generator module (12) is designed specifically to accommodate an electrosurgical tool (73) during LEEP or LLETZ proce-dures. The electrosurgical generator module (12) provides power to the electrosurgical tool (78) at a predetermined level. The smoke removal module (14) removes and filters smoke from the site of the electrosurgery.  A switching circuitry (60) activates the smoke removal module (14) substantially simultaneous to the activation of the electrosurgical tool (78) so that the smoke removal module (14) is activated automatically whenever the electrosurgical tool is activated. The switching circuitry (60) also delays the deactivation of the smoke removal module (14) after the electrosurgical tool (78) has been deactivated.  The electrosurgical tool (78) alternatively can be connected, concentrically or in parallel, to a smoke evacuation tube (80) in communication with the smoke removal module (14).
