  • Publication number: 20240150632
    Abstract: According to the present invention, there is provided a filler compound, the filler compound comprising filler particles and a binder, wherein the filler particles comprise particles of at least one glassy material, and the particles of glassy material are at least 10 wt. % of the dry mass of the filler compound, and wherein at least 30 wt. % of the filler particles have a diameter between 50 and 100 microns inclusive. Use of a filler compound in the erection of a structure is also described.

  • Patent number: 6793208
    Abstract: A tool system for inserting temple screws in eyeglass frames includes first and second scissor arms, with each scissor arm having proximal and distal ends, the arms pivotally connected so that the ends can be moved towards and away from one another when the arms are pivotally moved using finger-receiving devices at the distal ends of the scissor arms. A clamp locking mechanism is an extended ratchet device for providing stepwise engagement of the first and second scissor arms in a position where the finger receiving devices are moved closer together and prevented from moving further apart. Clamping and gripping surfaces at the proximal ends of the arms grip the spring hinge eyeglass frames, with an elongated projection extending away from the clamping surface on one arm to engage the eyeglass temples to temporarily secure the spring hinge in a state of extension.

  • Patent number: 5653019
    Abstract: A repairable, chip-to-board interconnect process which addresses cost and testability issues in the multi-chip modules. This process can be carried out using a chip-on-sacrificial-substrate technique, involving laser processing. This process avoids the curing/solvent evolution problems encountered in prior approaches, as well is resolving prior plating problems and the requirements for fillets.For repairable high speed chip-to-board connection, transmission lines can be formed on the sides of the chip from chip bond pads, ending in a gull wing at the bottom of the chip for subsequent solder.
