IPC: A61K35/74
Filed: 1998-05-22
Abstract: This invention provides materials and procedures for the delivery of selected strains of bacteria and/or oxalate-degrading enzymes to the intestinal tracts of persons who are at increased risk for oxalate related disease because they have lost, or have inadequate concentrations of these bacteria. The administration of these bacteria and/or the relevant enzyme removes oxalate from the intestinal tract and thus reduces the amount of oxalate available for absorption and reduces the risk for oxalate related disease.

Title: Blasting ignition assembly
Inventor: ROBERTSON J
IPC: F42D1/04
Filed: 1982-09-10
Abstract: An electrically actuable ignition assembly comprising an electric ignition element having insulated electrical leading wires connected by means of conducting metal contact elements to the ends of a secondary winding of insulated wire on a transformer ring core. The transformer core and contacts are preferably encased in a synthetic plastics case. The assembly is for use in blasting operations in which multi-shot rounds are fired from an a.c. supply by electromagnetic coupling of the supply with the secondary winding by means of a single primary wire threaded through the ring cores of a plurality of assemblies. The use of the metal contact elements eliminates the previously used soldered joints between the ignition element leading wires and the transformer secondary winding.
