Abstract: The present invention is directed to an improved form of a splint having a contact portion for maintaining the vertical separation of rearwardly opposed teeth in the oral cavity of a patient wearing the splint. The splint is provided with a contact portion for contacting opposed forward teeth to the forward teeth to which the splint is attached such that movement of the opposed forward teeth with respect to the contact portion maintains the spacing of the rearward teeth. The contact portion is provided with a central or intermediate section to which a forward portion is angularly inclined. The splint is optionally provided with a third portion angularly inclined to the central or intermediate portion for stabilising the position of the jaw or teeth to prevent permanent or long term change in the jaw position (strictly).

Abstract: A method and apparatus for making webbed plastic tubing suitable for use as a support for a filter pad in a cartridge filter. The webbed tubing is made by extruding a thermoplastic polymer in the form of a tube, cutting slits in the tube, and expanding the still warm and plastic tube by passing it over a mandrel slightly larger in diameter than the unexpanded tube.

Abstract: A non-woven fabric web is converted to a tubular shape by forming the web between a cylindrical mandrel and surrounding sleeve, and passing reciprocating barbed needles through the region where the sides of the web abut each other, to form a butt joint thereat. The apparatus includes a pair of rollers for drawing the tubular shaped web between the mandrel and sleeve, as well as a motor and control circuit for operating the reciprocating needles.

Abstract: A rotary filter apparatus includes a tank for containing a slurry to be filtered. A rotary drum is mounted for rotation about a horizontal axis. The drum has a filter surface which extends into the slurry, so that the filtrate may be withdrawn from the interior of the drum. An agitator in the bottom of the tank includes a vane mounted below the drum for rotation about a horizontal axis. The vane is driven to reciprocate through a driven angle about its rotational axis.
