  • Patent number: 4298595
    Abstract: An intestinal anti-inflammatory preparation comprising a polymeric agent for releasing 5-aminosalicylic acid or its salts is disclosed. The polymeric agent comprises a nonabsorbable pharmacologically acceptable organic polymer backbone containing aromatic rings to which are covalently bonded via azo bonds a plurality of salicylic acid or salicylate salt groups. The azo bonds attach to the salicylates' 5-position carbon. The polymer's azo bonds undergo bacterial cleavage in the mammalian lower bowel to release 5-aminosalicylic acid and/or its salts.

  • Patent number: 4134464
    Abstract: A system for bidirectional in-motion weighing of freight cars of a train includes a weighbridge, first and second sets of load cells, three wheel sensing devices, a control device, a device initiated by the control device for weighing operations, and a printer for the total car weight. The sets of load cells are mounted to receive the load from opposite ends of the weighbridge. Each set has a rapid change of output voltage when an axle enters or leaves the associated weighbridge end. The weighbridge is located between two spaced, aligned tracks and has a third track. The three tracks provide a path of train travel. Each wheel sensing device has a component to provide a signal when a wheel passes. Two components are mounted beside the first two tracks a predetermined distance from opposite ends of the third track. The third component is located beside one of the three tracks a predetermined distance from one end of the third track.
