Patent number: 4769272Abstract: A sidebrazed ceramic package is provided with a closure seal that employs a high alumina ceramic lid that matches the composition of the package body. The lid is provided with a recess in the sealing face and the sealing face is provided with metallization that adheres to the ceramic and is wet by solder. The metallized ceramic lid is sealed to the metallization ring on the sidebrazed ceramic body by means of the conventional gold-tin solder. The resultant hermetic seal can be insepcted by observing the solder fillet in the lid recess. Such a closure seal is fully hermetic and can readily survive repeated thermal cycling.Type: GrantFiled: March 17, 1987Date of Patent: September 6, 1988Assignee: National Semiconductor CorporationInventors: Robert C. Byrne, Jon T. Ewanich, Chee-Men Yu

Patent number: 4769262Abstract: The packaging of fresh fruit and vegetables is effected in a package at least part of which is made of a transparent film of a polymeric material. The film has a high rate of gas permeability and is impervious to the ingress of bacteria. As the fruit and vegetables continue to respire in the package an atmosphere is set up inside the package which serves to retard spoilage, mould growth and flavor deterioration, thereby providing the package with a longer shelf life than an open receptacle. The film is preferably polymethyl pentene and may form all the container or a lid to a rigid receptacle.Type: GrantFiled: November 19, 1986Date of Patent: September 6, 1988Assignee: Bunzl Flexpack LimitedInventors: Andrew N. Ferrar, Arthur N. Jones, Albert P. Taylor

Patent number: 4767653Abstract: Heat-sealable sheet material for use in the fabrication of lapped-seam membrane. In a presently preferred construction, linear low density polyethylene film is adhered to one lateral border of cured polymerized EPDM composition; preferably the adhesive is protected with a removable liner, e.g., a polyester film until lapped-seam splicing is to be carried out. A transfer tape based on thermoplastic heat-sealable adhesive carried by a strippable liner also constitute part of the invention. The transfer tape is advantageously applied to a sheet of uncured EPDM compound and the resultant assembly subjected to heat and pressure to cure the compound and bond the heat-sealable adhesive firmly thereto.Type: GrantFiled: November 12, 1985Date of Patent: August 30, 1988Assignee: Minnesota Mining and Manufacturing CompanyInventor: Richard L.

Patent number: 4767665Abstract: This invention describes a platable plastic material that uses a phosphide compound as a filler at levels of 5 to 40 weight percent. The phosphide filler used in this way has good dielectric properties and is non-conductive, but the phosphide provides coupling sites for a conductive plating to initiate and to bond to the filler and thus to the plastic. Surface treatment of the plastic may be needed to expose the particles but this invention removes requirements for catalytic treatment with noble metal chlorides and relies on bonding mechanisms other than the mechanical grip on a rough surface.Type: GrantFiled: September 16, 1985Date of Patent: August 30, 1988Inventor: Richard E. Seeger
