Title: Two-plane stacking container for liquids
Inventor: BOUTIN RAYMOND
IPC: B65D21/02
Filed: 1996-08-07
Granted: 2002-01-15
Abstract: A container for liquids is configured for two-plane stacking with one or two similarly constructed containers; it comprises a body having a rectanguloid configuration with a top wall defining a recessed liquid pouring spout area and a raised handle area. The bottom wall has an underface included within a downwardly extending peripheral border defined by a series of spaced legs and pockets between the legs. The configurations of the top and bottom walls allow such containers to be stacked in two planes: one plane includes containers one directly above the other or one above the other but vertically offset thereto; a second plane includes containers in vertical planes 90° to one anoother. The handle area has rectangular planar faces and a handle bar therebetween, both cooperating with the legs and pockets of one or two superposed containers to secure them in stacked relations.

Abstract: A method of deconvolving surface measured seismic signals reflected from a sub-surface sequence of geological formations, in which the sub-surface sequence of geological formations contains an areally stable acoustic impedance sequence. An inverse filter is derived from correlating a seismic signal with a synthetic seismic log weighted at the time location of the areally stable acoustic impedance sequence. This inverse filter is applied to stacked or pre-stacked seismic signals to produce a deconvolved seismic signal. In a particularly powerful embodiment of the invention, several inverse filters are derived in this manner at several geographic locations within the area of stability of the areally stable acoustic impedance sequence. These several inverse filters are then averaged to produce an average inverse filter which is used to deconvolve a seismic signal in the area of stability.      Apparatus for carrying out the invention is also disclosed.

Granted: 2001-07-03
Abstract: A  radio-based  system  for  a  train  including  a  lead transceiver unit and multiple remote transceiver units.  The lead  transceiver  unit  initiates  a  command  by  sending  a command message.  Each of the remote transceivers receiving the command message transmits a reply message which repeats the command message and contains the status of the sending remote.   Remote   transceivers   not   receiving   the   lead transceiver's  transmitted command message, but receiving  a reply message  from one  of  the  other  remote  transceivers, transmit a reply message containing the remote's status. The lead transceiver detects whether reply messages are received from the remote transceivers and may transmit a request in response. One or more remote transceivers may store and re-transmit reply messages from other transceivers in response to the request.

Abstract: A refiner disk or disk segment is cast from a stainless steel alloy having a composition of 0.2 percent to 0.4 percent carbon, 0.5 to 1.5 percent manganese, 0.5 percent to 1.5 percent silicon, a maximum of 0.05 percent sulfur, a maximum of 0.05 percent phosphorus, 14 percent to 18 percent chromium, 2 percent to 5 percent nickel, 2 percent to 5 percent copper, a maximum of 1 percent molybdenum, and 1.5 percent to 2.5 percent niobium, the balance being iron. The Niobium forms discrete carbides at high temperatures during the melting process. Upon cooling, the carbides are distributed evenly throughou t the structure. This resultant alloy provides toughness and corrosion resistance like a lower carbon alloy plus increased wear resistanc e due to the carbide formation. The alloy utilizes chromium to impart corrosion resistance, the process of tying up carbon as discrete, non - chromium carbides increases the amount of chromium present to provide corrosion resistance.

Title: Desiccant entrained polymer
Inventor: HEKAL IHAB M
IPC: B29C45/16
Filed: 1998-03-05
Granted: 2007-09-04
Abstract: The present invention includes processes and resulting structures for producing moisture absorbing desiccant entrained polymers. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. To achieve certain results in the hardened end product, such as rigidity and durability, the polymer normally acts as a moisture barrier in a solidified state, both before and after melting. A  desiccating agent is blended into the polymer so that the desiccating agent is distributed within the polymer. A channeling agent is also blended into the polymer so that it is distributed within the polymer. The blending of the components is preferably done before the polymer is caused to assume a molten state. Together, the polymer, desiccating agent and channeling agent create a blended mixture. The mixture is solidified so that the channeling agent forms passages in the mixture through which moisture is communicable to desiccating agent that is entrained within the mixture. The solidified mixture may be used to form plug type inserts and liners for closed containers, or it may be used for producing laminated sheeting employed as package wrap.
