Granted: 1996-02-20
Abstract: A cargo carrier (16) for pack animals having a side wall (18) and a bottom wall (28), with the bottom wall extending outwardly from a lower edge of side wall (18).   Both of these walls  (18,  28)  are preferably formed as a single monolithic unit of rigid material, such as aluminum.  The side wall (18) is curved about at least one line located on a side of the side wall opposite to that of the direction of extension of the bottom wall.  As such,  this curvature may conform to the side of the animal, thus distributing the pressure of the carrier and load more evenly upon the animal and providing greater comfort.  Various straps (42) may be provided to hang the side wall (18), and thus the bottom wall (28) and cargo from a crosstree saddle (14), or other type of pack saddle.  Various rings (52, 54) and straps (44, 48) are provided with the side and bottom walls to secure the cargo thereto.

Patent CA-2131267-C (CA)
Inventor: TURUDIC ANDY
IPC: H04B17/40
Filed: 1994-08-31
Granted: 2004-04-27
Abstract: A communications method and a network for carrying out the method are provided. The network includes a loopback command system and a first link station connected to a communications link. The link traverses several loopback-capable devices as it extends from the first link station to a second link station remote from the first link station. The loopback command system controls the loopback-capable devices to cause them to loopback. In order to command a loopback of a particular loopback-capable device, the first link station generates an initial loopback value and forwards the same over the link to a downstream loopback-capable device located along the link.      Each loopback-capable device receives a loopback value from an upstream device, and compares if the received value is equal to a predetermined value. If the loopback value is equal to the predetermined value, the device is placed into a loopback state. Otherwise, the loopback value is modified by the device, and the modified loopback value is forwarded to the next downstream device located along the link. The loopback value may be represented by a digital bit word, or by the position of a particular bit within a bit stream of the link.

Title: Methods of terminating undesirable gas migration in wells
Inventor: SAPONJA JEFFREY CHARLES
IPC: E21B33/138
Filed: 1994-11-10
Granted: 2000-04-25
Abstract: The present invention relates to a method of terminating undesirable gas migration in a well through one or more passages such as channels and microannuli in the cement sheath holding the casing in the well bore.  The methods basically comprise forming one or more lateral openings through the casing  and  the  cement  sheath  into  a  substantially  gas impermeable formation penetrated by the well bore.   One or more  horizontal  fractures  are  created  in  the formation extending from the lateral openings, and a fluid which sets into a substantially gas impermeable solid is deposited in the openings and fractures.  The fluid is permitted to set into a substantially gas  impermeable  solid  in the  openings  and fractures whereby passages in the cement sheath are plugged and gas migration is terminated.

Abstract: Chemiluminescent electron-rich aryl-substituted 1,2-dioxetane compounds are disclosed in which the aryl group is polysubstituted with suitable electron-donating groups such that the light-emitting pattern of the molecule results in a very high luminescent count, thus providing for a sensitive and precise assay for haptens, analytes, polynucleotides and the like. These substituted aryl-containing 1,2-dioxetane compounds can be used as direct labels in an immunoassay or when derivatized with an appropriate leaving group, can be used as a substrate for an enzyme immunoassay. The unusual chemiluminescence of the compounds allows the timing of the luminescent reaction to be exactly controlled.

Abstract: The system allows radio broadcast listeners to use a telephone to connect to a database that contains prerecorded audio descriptions (e.g- spoken text and/or music) of material played by the radio station. The database is indexed by the radio station's program schedule or play list to allow the user to select a particular audio description of interest (e.g. the song currently airing, the song last played, etc.). Hearing the audio description over the telephone insures the listener that the requested selection is in fact correct. By using the telephone DTMF touch tone controls, the listener can place an order to purchase the selected material over the telephone.

Title: Process for disposal of decomposable organic waste
Inventor: VORONEY R PAUL
IPC: C05F9/04
Filed: 1996-01-25
Granted: 2000-06-06
Abstract: A process for disposal of organic waste containing large quantities of fat or oil. A sample of the waste is decomposed in soil containingample quantities of nutrients required for decomposi tion, specifically nitrogen and phosphorus. Resulting test data indicates how much nutrient material is required for decomposition, and how much, and when, nutrient material is released to the soil after decomposition. The waste is then incorporated into soil in a field, and nutrients are applied to induce a rapid decomposition phase in which soil organisms absorb and immobilize the applied nutrients to decompose the waste and a subsequent mineralization phase in which the soil organisms release nutrients to the soil. A crop is appropriately selected and planted to begin absorbing significant quantities of soil available nutrients during the mineralization phase. The amount of applied nutrient material corresponds to crop growth requirements plus waste decomposition requirements less nutrients released during the mineralization phase, effectively reducing nutrient requirements is for rapid waste decomposition. Soil organisms and crop growth tend to immobilize soil available nutrients through the process, and no soil available nutrients remain after completion of the process. Leaching of nutrients to groundwater is minimized.
