Title: Air throttling valve for submerged pump
Inventor: HALL KEITH
IPC: F04D9/00
Filed: 1989-01-09
Granted: 1991-11-05
Abstract: AIR THROTTLING VALVE FOR   SUBMERGED PUMP SYSTEM           ABSTRACT OF THE DISCLOSURE            In a submerged pump system for pumping liquid from a well or vessel the vertical pipe through which the liquid is pumped by a submerged impeller pump is typically fitted at its upper end with an air valve. The air valve vents air from the pipe to atmosphere upon pump start up, then closes so that only water passes through a check valve to a pipe system and subsequently allows air to re-enter the pipe when the pump stops.  A special throttling valve associated with the air valve restricts the outward rate of flow of air to atmosphere to thereby reduce the rate of the rising liquid and thus the shock of this liquid on the air valve and on the check valve but allows essentially unrestricted re-entry of atmospheric air to thereby allow the vertical pipe to fill with air rapidly.  One form of throttling valve includes a valve plug mounted for axial movement into and out of a vent opening and spring-biased into the opening.  The plug is a loose fit within the opening, so that during venting the air passes through the restricted space between the plug and the wall of the opening.  Upon re-entry of air the force of the entering air moves the valve plug against the spring-bias and out of the opening in the direction of air flow whereby the opening is no longer restricted by the plug.

Title: Irrigation system
Inventor: WILLIAMS CHRISTOPHER G
IPC: A01G25/09
Filed: 1989-04-20
Granted: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE       An agricultural irrigation system for operation along an elongated pressurized water main having sections of land adjacent opposite sides thereof.  The water main includes spaced, normally closed, access valves.  The irrigation system has a length of water delivery pipe to extend from the water main.  Carts support the length of water delivery pipe for forward movement along the ground surface.  There is a drive on the cart for moving the cart and water delivery pipe transverse to the delivery pipe.  Water applicators are located along the delivery pipe for selective water application.  The delivery pipe can be rotated to control the drive to rotate the length of water delivery pipe to a position along the water main from one side to an opposite side so that the same length of water delivery pipe may irrigate two sections of land.  There are connectors on the delivery pipe for selectively connecting the delivery pipe to and opening the normally closed access valves.  The connector includes a valve coupling on the delivery pipe for selective engagement with the individual access valves to open the valves such that water is delivered through the delivery pipe.  The connector also has swing arms having a free swinging end mounting the coupling and a remaining end attached to one end of the traveling water delivery pipe to guide the coupling between access valves.  A pivot mounts the swing arm to the water delivery pipe for angular movement.       There are valve coupling travel devices to support and move the free swinging end of the swing arm, to transport the valve coupling between valves, and valve coupler rotation devices to allow horizontal rotation of the swing arm when connection is made to an access valve and the remaining swing arm end is carried forward by the delivery pipe.  Delivery pipe positioners maintain the delivery pipe aligned with the main during forward travel of the delivery pipe and subsequent water application.  A control associated with the valve coupling, valve coupling travel device, and delivery pipe positioner controls the uncoupling, travel, and coupling of the valve coupling along the series of access valves.

Abstract: This invention relates to apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger (10) of the continuous type, comprising a large number of vertical heat exchanger tubes (18) mounted between a lower chamber (17) and an upper chamber (16) within a jacket (15). Within the tubes (18) small solid particles are kept in a fluidized condition by the fluid medium passing up from the lower chamber (17) through the tubes (18), so as to achieve a good heat transfer, whereas also any deposit will be removed from the innertube walls. Forthe downward flow of the granular mass at least one return tube (21) is provided. Downward circulation of the fluid medium through the return tube (21) should be minimal, however, which can be achieved by an increase of the pressure difference between the upper and lower chamber (16; 17), which increase of the pressure difference can be achieved by fitting several distribution plates (24; 42) at a level above the return tube (21) outlet into the lower chamber (17), preferably so thatthe apertures in the various distribution plates (24; 42) of the multiple design are not vertically in line.The second distribution plate (42) also serves to minimise excessive wear of the material of the jacket (15) due to the eddying motion of the granules.
