Abstract: A precision electric welding device is used for welding dental crowns and bridges in the mouth. The dental elements to be welded comprise dentally suitable metals, especially titanium and titanium alloys. The device comprises a welding gun and a base unit provided with a direct current voltage source and a storage device for storing welding sequences. Each welding sequence defines the energy requirements for successive pulses in a particular welding operation. The base unit generates a series of controlled voltage potentials for each operation, and the welding gun is responsive thereto for performing the welding operations. The portable welding system is of the capacity-discharge, contact-resistance type, and performs welding with high-precision endo-oral metals by generating controlled sequences of electrical energy pulses (1) selected from a permanent storage library, or (2) manually controlled from a local console, or (3) externally controlled from an external computer.

The reaction arm encompasses the clamp wheel through a maximum of 180 degrees.

Abstract: A coincineration process whereby sewage sludge or other toxic liquid chemical waste is incinerated with a supplemental fuel such as municipal refuse, coal, sawdust, tire chips and the like involves introducing the sewage sludge into the incineration zone by means of a pressure spray nozzle or a spinning cone or disc atomizer. In the form of ultrafine solids, liquid or gas, a supplemental fuel may be introduced with the sewage sludge. Supplemental fuel may also be introduced into the incinerator by conventional means. Addition of tire chips in the feed provides in a higher incineration zone temperature and significantly reduces dioxin compounds present in the incineration zone off gas. Also, to reduce the scaling and fouling of the boiler tubes and incinerator, to increase the density and pumpability of the sewage sludge, and to eliminate metal salt deposits from the incinerator, the boiler feedwater and the sewage sludge are each contacted with an electromagnetic field device prior to heating.

The diaphragm is increased in rigidity which is required as physical properties therefor and is easy in forming.

Abstract: Dental crowns, bridges and jointing implements or tabs for dental prostheses which are capable of being welded in the mouth are disclosed. These structures are preferably comprised of high purity titanium alloy. The dental crowns are formed as a cast or prepressed central cap in the shape of the tooth to be treated. The crown is additionally provided with one or two tabs which correspond to one or both of the linking sides of the crown with an adjacent crown. The titanium jointing tabs are designed for coupling and welding in the mouth and may be used with crowns or bridges of conventional structure such as gold or a gold alloy. Each jointing implement is provided at one end with a shaped element such as a screw to be rigidly coupled to the crown. The jointing implement is also optionally provided with one or more microindentations on the inside lateral surface to facilitate welding in the mouth with the jointing implement or tab of the crown element associated with the adjacent tooth.

This reduces the chance of damage to the operating mechanism should the handle be operated when the mechanism is jammed. The wheels are set in rotation by spring loaded fingers which drive said wheels, said fingers being moved to their loaded position by said clutch and engaging a stop to causing said clutch to release the fingers which spring back and spin the change wheels.

Abstract: A device for removing irregularities in or enlarging a buried duct comprises a cylindrical housing corresponding approximately in diameter to the required diameter of the duct, an expandable sheet comprising a plurality of tapered leaf members pivotally attached at their rear ends to the front of the housing, and remotely controllable drive means for moving the leaf members between contracted and expanded configurations. In operation, the apparatus is drawn through the duct with the leaf members in a contracted configuration in which they enter a portion of the duct of a diameter less than the required diameter. The drive means is operated to force the leaf members outwardly against the sides of the duct to expand the duct. The leaf members are then retracted and the apparatus is drawn forward. The apparatus is particularly intended for preparing damaged sewers prior to fitting an inner, lining pipe.
