Abstract: A pressure resistant system for joining concrete pipes in an end to end relationship is disclosed. The first pipe terminates in a bell end and the second pipe terminates in a spigot end with the spigot end surrounded by a seal member and the inner surface of the bell also surrounded by a seal member. Each seal member has internal ribs which extend into and are embedded in the concrete pipe. The spigot end sealing ring includes an internal flap extending substantially perpendicular thereto across an internal offset face of the spigot and a lip extending across a portion of the end face. A rib of reduced length is disposed adjacent the lip and midway between the lip and the flap. In one embodiment the spigot and sealing ring defines a concave groove for receiving an O-ring seal, and in another embodiment the concave groove is replaced by an integral convex seal portion.

Abstract: Controlled release pesticide-polymers are prepared by reacting a polymer having a pendant group containing a reactive hydrogen with a chloroformamide derivative of a pesticide. In a preferred embodiment, metribuzin chloroformamide is prepared by reacting metribuzin with phosgene at a temperature of about 40.degree. C. The metribuzin chloroformamide is then reacted with cellulose to form a pesticide-polymer from which the metribuzin is released under use conditions by hydrolytic degradation of the carbamate bond attaching the metribuzin to the polymer.

Abstract: An improved seal system for the bell and spigot joint of a concrete pipe. The seal includes a bell sealing ring and a spigot sealing ring, each constructed of plastic material which when the spigot is received in the bell form a compression seal which will withstand substantial internal pressure without leaking. The ring members include, respectively, outwardly directed and inwardly directed ridges or flanges which are embedded in the respective bell and spigot ends of the concrete pipe. The spigot end ring, however, includes a central concave depression which extends into the concrete and receives an O-ring, and a lower depending flange also embedded in the concrete forming the spigot end. The joint of this invention then forms a reinforced concrete pipe capable of withstanding substantial internal pressure at least up to 50-60 pounds per square inch.

Abstract: A flow switch apparatus and method for use in determining the quantity of a beverage liquid passing through a conduit, the apparatus including a light path across the conduit and an actuator arm interposed across the light path, the actuator arm being activated by fluid flow through the conduit. The light path is formed by a light source transmitting light toward a light detector. The light detector produces an electronic signal when adequate light received by the light detector. The signal produced by the switch apparatus is in the form of digital logic voltage levels which can be monitored remotely by conventional electronic apparatus to accumulate the flow information provided by the flow switch. The conduit is adapted to be vertically oriented to accommodate the actuator arm resting under gravity in occulusion of the light path when there is no fluid flow in the conduit.

Abstract: A flowmeter apparatus and method for use in measuring the quantity of liquid beverage passing through a tubing, the apparatus including a flowmeter wheel adapted to be turned by the flow of beverage through the tubing. The flowmeter wheel is interposed in a light path between a light source and a light detector with a plurality of apertures in the flowmeter wheel permitting light passage through the light path to the light detector. Rotation of the wheel creates a series of light pulses that are detected by the light detector and are electronically counted to thereby provide an indication of the amount of beverage passing through the flowmeter and, correspondingly, the tubing.

Abstract: An end sealing member joined to the ends of a pipe for cooperation with a complementary end sealing member on another pipe to seal the joint formed when at least two such pipes are joined in end-to-end relationship. Each end sealing member has upstanding members extending into the surface of the pipe to seal the interface between the sealing member and the pipe to which it is secured. The exposed surface of one sealing member is configured to sealingly engage the exposed surface of a complementary sealing member when the one sealing member is telescoped over the other in forming the joint between the two pipes.
