Title: Process for the production of a metal melt
Inventor: BERGER HARALD
IPC: C21C5/38
Filed: 1993-07-15
Abstract: ABSTRACT OF THE DISCLOSURE:   In a process for the production of a metal melt in a metallurgical vessel, the filter dusts incurring in producing the metal melt are to be processed to charging substanceswithout causing a load on the environment and without great expenditures.   This is achieved in that the filter dusts are introduced into the metallurgical vessel by aid of a gaseous conveying medium composed of natural gas or a mixed gas primarily containing natural gas, the filter dusts being supplied to the metallurgical vessel in a closed system and reduced by the carrier gas.

Patent CA-2116586-A1 (CA)
Title: Baseboard with movable electrical outlet
Inventor: GLEN BRYAN DAVID
IPC: H01R25/14
Filed: 1992-08-28
Abstract: Existing electrical outlet tracks require that the outlet be slid from one location to another along the track. The present invention provides a readily movable electrical receptacle which also discourages contact with the conductors. The receptacles of the present invention can be readily installed at any location along a baseboard conductor without sliding of the receptacle. This is accomplished using a T-shaped element which is inserted through the lengthwise groove of the continuous track and rotated into place. Screw-mounted bars arc used to tighten the receptacle into place at the chosen location.       Multiple raceways on a single baseboard, accommodating different types of receptacles, are disclosed.

Abstract: A square saw tooth having four cutting edges of the type which is rotatable about its axis on a saw disc to present a fresh cutting edge when the radially outermost edge wears out has carbide wear plates covering the high wear areas of its attack face and providing its cutting edges.  A wear plate is provided at each corner of the attack face, and each wear plate has a flat rear surface for attachment to the tooth body and a front surface of a complex shape, having plateau surface areas at the corners, where the plates are thicker, and curved surfaces which recede from the plateau areas toward the interior of the attack face, so that the plate recedes in thickness away from the plateau area.  This construction helps provide more uniform wear over the surfaces and edges of the attack face for a more efficient consumption of the wear plates.          In an alternate embodiment, the plateaus are provided at the corners of a tooth having a spherically concave attack face so as to inhibit wear of the corners.

Abstract: An arrangement for connection of wiring backplanes and module circuit boards wherein individual contact passages arranged in a housing are surrounded by electrically conductive shielding plates that are connected to contactings that carry shield potential. They are attached in the intermediate grid both at the backplane side as well as at the assembly side, and are charged with a corresponding potential. In order to create a connector arrangement for extremely high transmission frequencies and good transmission properties, terminal ends of spring elements of the sheet metal shielding compartment and terminal ends of the spring elements of shielding plates of the contact passages abut with a contacting layer of precious metal at the backplane side. Both the spring elements of the shielding plates arranged perpendicular to the wiring backplane as well as the spring elements of the shielding compartment proceeding perpendicular to the wiring backplane are corrugated. Terminal lugs are provided on the precious metal layer on the wiring backplane in the cooperating region of the terminal ends. The housing is mechanically secured to the wiring backplane at a plurality of locations.

Title: Device for controlling the opening and chosing of safety gripping jaws on a pressure vessel
Inventor: CHAMEROY ERIC
IPC: A47J27/08
Filed: 1995-07-04
Abstract: The lid has a pair of radially-mounted jaws connected to a central actuating mechanism by a pair of transverse drive rods. A mobile control member (56) is located centrally on a control knob (50), for reciprocating movement in a direction radial to the knob and the lid.   Manual pressure moves the control member radially inwards, actuating the drive rods via a mechanical connection to move in a radially outward locking direction. The control member is linked to a control button (52), such that manual downward pressure on the button causes the control member to move radially outwards and the drive rods to move in a radially inward unlocking direction. The control member and button together form a central gripping handle for the lid. <IMAGE>
