  • Patent number: 12097568
    Abstract: An apparatus and method for fastening layers of non-ferrous alloys, like aluminum, magnesium and copper utilizes a steel fastener and a spot welding machine. The fastener and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the fastener to penetrate the aluminum. A weld zone between the fastener and the various layers creates an internal weld. The fastener has a rough shaft that is coated by the molten weld zone and is hard to withdraw on solidification. Layers of non-conductive materials like plastics and ceramics may also be affixed to a conductive layer using a fastener made from a compatible material that extends through a pilot hole and welds to or penetrates a conductive layer. The fastener may have projections that initially reduce contact area with the stack.

  • Publication number: 20240291174
    Abstract: An apparatus and method for fastening dissimilar materials like steel, plastic and aluminum. A resistance welding fastener having multiple layers may be used with or without a sealant. The fastener may be used to form an aluminum covered steel laminate via a hemming pattern of attachment. The fastener may have a solid shaft or have an extended reach and have features for interacting with the welding electrode. A variety of electrode tips may be employed to cooperate with the fastener.

  • Patent number: 12042876
    Abstract: An apparatus and method for fastening dissimilar metals like steel and aluminum utilizes a steel rivet and a spot welding machine. The rivet and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the rivet to penetrate the aluminum and weld to the steel layer. The fastener may be used to join stacks with several layers of different materials and may be used to apply a threaded socket or stud made from steel or titanium to an aluminum or magnesium alloy structure. Layers of non-conductive materials like plastic and ceramics may also be affixed to a conductive layer using the fastener made from a compatible material that extends through a pilot hole.

  • Patent number: 9943603
    Abstract: The present invention is directed to a monomer useful in preparing therapeutic compounds. The monomer includes a diversity element which potentially binds to a target molecule with a dissociation constant of less than 300 ?M and a linker element connected to the diversity element. The linker element has a molecular weight less than 500 daltons, is connected, directly or indirectly through a connector, to said diversity element, and is capable of forming a reversible covalent bond or non-covalent interaction with a binding partner of the linker element. The monomers can be covalently or non-covalently linked together to form a therapeutic multimer or a precursor thereof. Also disclosed is a method of screening for therapeutic multimer precursors which bind to a target molecule associated with a condition and a method of screening for linker elements capable of binding to one another.
