Abstract:
The container includes a first chamber connected to the liquid source through an inlet port of a given cross-sectional area and a second chamber connected to a drain through an outlet port of at least equal size. The chambers are separated by a partition having a slot which has an elongated portion extending from the container floor in a direction generally parallel to the container side walls. The area of the elongated slot portion is approximately equal to the area of the inlet port. Liquid level or weight sensors generate signals representative of the quantity of the liquid level in the first chamber to a microprocessor to measure the flow rate. The signals are integrated over time to measure the total volume.
Abstract:
A panel having high strength relative to its weight is made of rigid material and is formed with a plurality of open cells, each open at one side, and with a plurality of closed cells, each closed on all sides. Each of the open cells is surrounded on all its sides by a plurality of the closed cells, and each of the closed cells is surrounded on all its sides by a plurality of the open cells.
Abstract:
A double-wall container comprises outer side walls integrally formed with semi-tubular ribs extending heightwise of the container and joined at their apices to the inner side walls of the container, and an outer bottom wall also integrally formed with semi-tubular ribs which extend transversely of the container and join at their apices to the inner bottom wall. The inner side walls of the container are formed with inwardly-curved corners extending heightwise of the container, and the outer side walls are formed with outwardly-curved corners extending heightwise of the container and complementing the inwardly-curved corners of the inner side walls to define therewith tubular columns at the corners of the container.
Abstract:
Liquid, such as milk, enters the sealed container from an inlet at the top of the container and exits through an outlet at the bottom of the container. The quantity of liquid in the container is sensed and a microprocessor calculates the total volume of liquid. During periods of low flow, such as at the beginning and at the end of the milking cycle, the outlet is automatically closed, partially or completely, by a motorized valve connected to the microprocessor, or by a weighted float situated within the container, so as to accumulate the liquid during those periods thereby enhancing the accuracy of the measurement.
Abstract:
An electrically-operated control valve includes a rotor rotatably mounted to a first position connecting a fluid inlet port to a fluid outlet port, or a second position disconnecting the fluid inlet port from the fluid outlet port; a battery-operated electrical rotary motor for rotating the rotor; and limit switches for deenergizing the electrical motor when the rotor arrives in either the first or second positions. The electrical motor is coupled to the rotor by a speed-reducing, torque-increasing transmission such that very little electrical power is required to operate the motor, thereby enabling the control valve to be used as a remotely-controlled pilot valve for controlling a water irrigation system.
Abstract:
A high pressure plastic container is made by rotationally moulding a first wall of plastic material, and a second wall enclosing and bonded to the first wall. One of the walls is integrally formed with a plurality of circumferentially-extending axially-spaced ribs of a hollow construction. The other wall may be unribbed, or may be integrally formed with a plurality of axially-extending circumferentially-spaced hollow ribs. The hollow ribs, are filled with a rigid plastic foam.
Abstract:
An irrigation system comprises a water supply line located on the ground having a plurality of equally spaced valve assemblies and an irrigation machine movable along the water supply line. The irrigation machine comprises a base frame situated on the ground to move along the water supply line, propelling means provided on the base frame for moving the base frame along the water supply line at a constant speed, water transfer means on the base frame for supplying water onto the ground, and a coupling assembly on the base frame. The coupling assembly includes at least two coupling sections connected to each other to freely move relative to the base frame so that when one of the coupling sections is moved in one direction along the longitudinal direction of the base frame, the other coupling section is moved in the opposite direction along the longitudinal direction of the base frame. The coupling sections are connected to the water transfer means at respective ends and are engaged at the other end with one of the valve assemblies of the water supply line alternately. At least one of the coupling sections is always connected to one of the valve assemblies.
Abstract:
Method and apparatus for making a honeycomb structure including a honeycomb core in which a plurality of preformed honeycomb core elements are moved through an extrusion machine, while a layer of a plastic material is simultaneously extruded over the opposite faces of the honeycomb core elements.
Abstract:
Water irrigation apparatus comprises a water supply pipe divided into a plurality of sections each formed with a plurality of water outlets spaced along its length; pivotal connections connecting the ends of each section to the ends of the adjacent sections to form a line of sections articulated at their ends; a wheel carried by each section for propelling the respective section over the ground; and horizontal aligning means for each section effective to couple or decouple the wheel of each section to its respective section in response to the angle between it and the next adjacent section.
