rat Method and apparatus for interlocking load carrying elements By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT A method for interlocking structural steel components with a metal-filled interlock is disclosed herein. The method comprises placing a mold about aligned contoured portions of structural steel components and attaching a crucible and a spout to the mold. The crucible is charged with exothermic reactive metals which are ignited, forming a molten metal filler. The molten metal filler melts a metal plug in the crucible or spout and the molten metal filler flows into the mold and about the aligned contoured portions of the structural steel components. Cooling of the molten metal filler forms a metal-filled interlock. Molds for performing the disclosed method are also disclosed herein. Full Article
rat Tower pump casting apparatus By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT A casting apparatus having a main chamber connected to at least one casting tower. The main chamber may contain molten metal and the temperature within the main chamber may be maintained by a furnace. A pump may pump the molten metal up the tower and into an upper pool chamber. A feeder nozzle may feed the molten metal from the upper pool chamber and onto a chilling wheel, which may turn the molten metal into metal flakes. Full Article
rat Multiple casting apparatus and method By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT Apparatuses and methods of forming battery parts are disclosed herein. In one embodiment, a method of forming a battery part includes receiving a flowable material into a cavity, and reducing a volume of the cavity while a pin extending through at least a portion of the cavity remains at least generally stationary therein. The method further includes sealing the cavity by slidably engaging at least a portion of the pin with a recess in the piston proximate the end face of the piston. Full Article
rat Method for producing a trailing arm of a twist beam axle in which a drive unit of an electrical drive close to the wheel, comprising an electrical engine and a transmission, is integrated By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A method of producing a trailing arm of a torsion beam axle in which an integrated drive unit of a wheel-adjacent electric drive has an electric machine and a transmission. By using the method, the trailing arm is produced in the form of a casting with a box profile. The contours for producing the area that accommodates the transmission, the connection point to the vehicle body, the bore that receives the cross-member which connects the two trailing arms to one another, the U-profile of the trailing arm, the box profile and the area that accommodates the electric machine, are modeled by cores such that the contours for producing the connection point of the trailing arm to the vehicle body, the bore that receives the cross-member and the U-profile of the trailing arm are modeled by one core.

The apparatuses and methods include a fluid purification apparatus and a level sensor that regulates operation of the fluid purification apparatus. The level sensor may further operate a bypass valve or a heater. Full Article
rat Oil recovery apparatus By www.freepatentsonline.com Published On :: Tue, 04 Feb 2014 08:00:00 EST A method and apparatus for recovering oil from oil-containing sorbents, such as drill cuttings obtained from drilling with an oil-based mud. The method includes peptizing the substrate with an acid reagent and direct thermal desorption with combustion effluent gases at high temperature under turbulent mixing conditions. Another method disclosed includes upgrading the oil in the substrate to improve one or more of the properties of the recovered oil relative to the oil in the substrate, such as, lower aromatics content, lower sulfur content, lower functional group content, higher saturates, higher viscosity, higher viscosity index, and any combination thereof. The apparatus provides for efficient recovery of oil from the substrate with a short residence time, high throughput, low residual oil content in the treated solids and/or high percentage of oil recovery. The apparatus may be transported to a remote location for on-site treatment of drill cuttings or other oil-containing solids. Full Article
