Title: Selectively opened bi-directional cracking valve
Inventor: POLI ROBERT G
IPC: A61M39/28
Filed: 1994-11-25
Abstract: A bi-directional cracking valve that can be selectively opened. Bi-directional cracking valve (10, 70) is formed using an elastomeric membrane (34). Centered within the elastomeric membrane is a slit (36) that remains closed, blocking fluid flow tbrough the device until a differential pressure across the elastomeric membrane exceeds a predefined cracking pressure, sufficient to force fluid through the slit. The elastomeric membrane is an integral part of an elastomeric cylinder (28), which is mounted in a valve carrier (12). The valve carrier includes ports disposed at opposite ends and theports are adapted to couple to tubing. An operator can selectively enable fluid flow tbrough the device by squeezing side tabs (40, 42) disposed on opposite sides of the elastomeric membrane together, forcing the slit open. A latch (46) is provided to keep the bi-directional cracking valve in an open state.

Patent CA-2178517-A1 (CA)
Title: Neisseria meningitidis capsular polysaccharide conjugates
Inventor: KANDIL ALI
IPC: C12P21/08
Filed: 1996-06-07
Abstract: Capsular polysaccharides containing multiple sialic acid residues, particularly the Group B polysaccharide of Neisseria meningitidis, are modified by chemical reaction to randomly introduce pendant reactive residues of heterobifunctional linker molecules to the polysaccharide backbone. The capsular polysaccharide is deacetylated and the heterobifunctional linker molecule is reacted with the deacetylated material and any residual amino groups are blocked by reaction with alkyl acid anhydride. The introduction of the linker molecules to the polysaccharide chain between the termini enables the polysaccharide to be linked to a carrier molecule, such as a protein, to enhance the immunogenicity of the polysaccharide. The conjugate molecule may be formulated as an immunogenic composition for raising antibodies in a host to the polysaccharide.

Inventor: DALLMAN JIMMIE J
IPC: F15B11/028
Filed: 1996-07-31
Abstract: A flotation control system for controlling the boom of a tractor or brush cutting machine. Three hydraulic valves operate together and work in conjunction with the existing main valve of the tractor or brush cutting machine to provide flotation control or automatic movement up and down of the boom in response to ground surface variations. The system also allows the amount of weight that the cutter or other attachment exerts against the ground to be increased or decreased. The first valve is a flow control valve or a flow restricting or dividing valve that divides hydraulic flow from the pump of the tractor to the flotation control system. The second valve is a pressure reducing valve that provides the general operation of the flotation control system. The third valve is a directional valve and functions as an on/off for the flotation control system. The third valve allows a float mode by moving a cylinder which is already present in the tractor hydraulic system up or down to control movement of the boom up or down. The system is used in either a closed center or open center hydraulic system. A method of providing flotation control for controlling the boom of a tractor or brush cutting machine is also disclosed.

Title: Method and apparatus for sterilization of seeds, herbs and spices
Inventor: SIEGMUND MICHAEL L
IPC: A23B7/005
Filed: 1995-12-29
Abstract: The present invention provides a method for sterilizing seeds, herbs and spices while minimizing the loss of volatile oils from the product. The seeds, herbs, and spices are fed from a hopper (116) to a sterilizer (112). Sterilization is carried out by quickly heating the surface of the seeds, herbs and spices with steam or other heating agent under greater than atmospheric pressure to reduce the microbial load substantially without volatilization of oils in the product. The product is then quickly cooled under greater than atmospheric pressure in a pressure vessel and cooling chamber (124). carrying out the cooling under pressure reduces the volatile oil loss due to flashing and hence substantially retains the original aroma and flavor of the sterilized product. The cooled product may then be discharged from the cooling chamber (124) to a dryer (130).

Title: Self-extinguishing burning bar
Inventor: SAUNDERS GREGORY J
IPC: E21B7/14
Filed: 1997-02-25
Abstract: A metallic pipe may be used as a burning bar if the pipe contains wires. The wires are usually steel but may be combinations of steel wires, aluminum wires, magnesium wires and the like. To use the burning bar one end is heated to at least red hot condition. Oxygen is then pumped down the pipe and the pipe then produces a self-sustaining high temperature, high heat flame. A burning bar may be used for demolition and similar uses. In this improved burning bar, the wires within the pipe are arranged so that the wires do not extend the full length of the pipe.     There is a portion of the pipe adjacent to the end of the pipe held by the operator which does not contain any wires. The pipe is thus self extinguishing at the point where the wires cease thereby providing safety to the operator and economic advantages.

Patent CA-2205836-A1 (CA)
Inventor: VARMA HERMAN P
IPC: G06F17/30
Filed: 1995-10-31
Abstract: An improved database data structure and datatype is disclosed for storing, manipulating and accessing multidimensional spatial data in a database. Binary helical hyperspatial code (HH CODE) is used to represent data of N dimensions. The binary HH CODE data structure maintains the dimensional organization of multidimensional data within the data itself. Spatial data is stored using BH code which is modeled as a N-tree structure derived using recursive decomposition.  A high water mark is set as the upper limit for data volume which may be stored in any one partition. As data stored in a partition exceeds the high water mark, the data is decomposed into child partitions such that no partition data stores exceed the high water mark. If the high water mark is exceeded, additional child partitions are automatically created and the parent table is not retained. A data structure is defined which represents the partitioned tables and BH code values. Appropriate attributes are associated with each of the BH code values which may represent non-spatial data such as temperature, salinity, or cosmic ray flux. Methods and apparatus are also provided to apply teachings of binary HH CODE to line segments and topology.
