Abstract: A telescoping shipping container for fragile articles and formed of corrugated sheet material includes an upper portion and a lower portion, each respectively having an upper end and a lower end with standard flap closure. The upper portion telescopes completely over the lower portion, to effectively double the thickness of the side walls of the package. The inner/lower portion includes a complete lining of resilient foam padding for further protection of articles contained therein; the inside of the upper lid is also similarly lined.  By forming each portion of double plies or laminates of corrugated material, the sides of the closed package or container effectively include four corrugated layers, which along with the resilient foam lining, provides superior protection against penetration and damage to the package. The corrugated material may be cardboard, plastic, or other suitable sheet material capable of being similarly formed. A reusable seal or closure, is included so that the package may be reused, if desired. The packaging is particularly valuable for the shipping of personal computers and related components, but may be used for shipment of virtually any fragile article, depending upon the specific interior padding used.

Abstract: Sont décrits des substrats revêtus d'un déshydratant, des roues de déshumidification rotatives régénérables et d'autres dispositifs utilisés pour le traitement d'un gaz (par exemple l'air) dans lesquels on utilise de tels substrats, ainsi que des procédés permettant de fabriquer ces substrats. Lesdits substrats peuvent être pourvus d'un revêtement dont l'épaisseur varie entre environ 2 et environ 10 millièmes de pouce (c'est-à-dire d'environ 0,051 à 0,254 mm) et contenant des particules d'un ou de plusieurs déshydratants adsorbants et un liant organique à base d'eau. Les particules de déshydratant conservent une grande partie de leur capacité d'adsorption d'origine, étant donné que les pores des particules de déshydratant contiennent un agent de déblocage des pores avant la prise du liant et que cet agent de déblocage quitte les pores pendant le processus de fabrication pour empêcher que le liant bloque lesdits pores. Selon des modes de réalisation préférés, un mélange de différents déshydratants est utilisé et un agent de mise en suspension des particules maintient des particules bien mélangées de sorte que les particules de déshydratants soient aussi bien mélangées que possible sur le substrat pourvu de son revêtement. L'agent de mise en suspension peut également jouer le rôle d'agent de déblocage des pores. Un agent de réglage du pH peut être utilisé pour régler le pH du revêtement, si le liant ou un autre constituant du revêtement est sensible au pH.

Granted: 1999-04-27
Abstract: A semiconductor integrated circuit comprises a conductive protein electrode, such as cytochrome C, deposited on the surface of an apatite insulating layer such as hydroxyapatite, fluorinated apatite or chlorinated apatite.  The apatite insulating layer is thin film coated onto a substrate such that it is C-axis (002) oriented, which allows the integrated circuit to be of small size while minimizing undesired electron transfer between electrodes because the conductive protein electrode adopts the orientation of the apatite insulating film.

Title: Method for maintaining mailpiece integrity
Inventor: ZUIDEMA ERIC L
IPC: G07B17/04
Filed: 1996-05-03
Granted: 2009-10-13
Abstract: A method for maintaining mailpiece integrity in a mailing system when a mechanical module experiences an error. For one category of errors, the mailing system may automatically recover from the error without operator intervention. For the remaining category of errors, the mailing system may recover from the error with minimum operator intervention, that is, the operator may be required to only remove the error producing mailpiece. A  motion control processor for an error producing mechanical module will report a fault to its corresponding mailpiece builder task and the error detector task.  Movement of at least the error producing mailpiece shall stop. The fault will be reported to the mailpiece builder tasks corresponding to the mechanical modules having no error condition. The mailing system shall suspend further processing of mailpieces upstream from the error producing mailpiece. For one category of errors, the mailing system will purge the error producing mailpiece from the error producing module without operator intervention. For the remaining category of errors, the operator will be required to remove at least the error producing mailpiece. State machines are then selected to perform system wide job recovery.
