Abstract: Diaphragm interface apparatus to improve a cycle life of a diaphragm are described. An example fluid regulator includes a fluid flow passageway between an inlet and an outlet, where a sensing chamber defines a portion of the fluid flow passageway. A diaphragm senses a pressure in the sensing chamber and a diaphragm interface adjacent the sensing chamber has a curved surface to contact a portion of the diaphragm that moves in response to pressure changes in the sensing chamber. The curved surface affects an amount of stress imparted to the portion of the diaphragm during operation of the fluid regulator.

Abstract: Dome-loaded pressure regulators are disclosed. An example pressure regulator includes a body having a pressure inlet and first and second pressure outlets and a first dome-loaded pressure regulating valve fluidly coupled to the pressure inlet, the first pressure outlet, and a first control pressure. The first dome-loaded pressure regulating valve includes a first piston having a transverse bore defining a fluid path through the first piston to fluidly couple the pressure inlet to the first pressure outlet and configured to engage a first valve seat and to respond to the first control pressure to control the flow of fluid between the pressure inlet and the first pressure outlet via the first valve seat. The example pressure regulator includes a second dome-loaded pressure regulating valve fluidly coupled to the pressure inlet, the second pressure outlet, and a second control pressure.

Abstract: A cell-type filter unit having two or more filter media layers and/or zones, at least one of the layers/zones having a different particle retention capability disposed on each side of a non-filtering separator element. The filter media are preferably positioned such that each succeedingly distal filter layer or zone from the separator has a decreased particle retention capability than each proceeding filter layer or zone. The filter media layer most proximal to the separator element may be separated from the separator by a support material for supporting such filter media element and preventing collapsing of the media into any separator conduit.

A piston is disposed in the body and fluidly coupled to the pressure inlet, the pressure outlet, and the pressure control inlet. The piston is configured to contact a valve seat and to control the flow of fluid from the pressure inlet to the pressure outlet in response to a pressure applied to a surface of the piston via the pressure control inlet.

Abstract: An apparatus for vacuum coating, including a vacuum chamber including at least one magnetron (2), each magnetron holding a target including at least one metal sheet (24) from which metal particles are transferred to a surface of a receiving item. The magnetrons have a channel system for supplying and discharging coolant. The magnetrons (2) preferably include an elongated body having mutually movable and interacting parts which are an outer part (14) having a longitudinal cavity and which outwardly at opposite sides of the cavity has inwardly facing holder members (12) and an inner part (18) located in the longitudinal cavity. these inner parts outwardly along opposing sides has edge parts for interacting with the holder members for clamping the target (24), which in size is adapted to the magnetron (2). Each of the magnetrons includes means for displacing the inner part (18) in relation to the outer part (14).

Abstract: A fluid filtration unit having two or more filter medium layers and/or zones, at least one of the layers/zones having a different particle retention capability disposed on each side of a non-filtering separator element. The filter medium are presently preferably positioned such that each succeedingly distal filter layer or zone from the separator has a decreased particle retention capability than each proceeding filter layer or zone. The filter medium layer most proximal to the separator element may be separated from the separator by a support material for supporting such filter medium element and preventing collapsing of the medium into any separator conduit. At least one of the medium elements is formed from a material which swells in size due to fluid absorption with the various zones and the separator being operatively connected by a new and innovative edge seal.

Abstract: A device which is easily attached to the side of a scaffold for lifting objects up the side of the scaffold. The device consists of a carriage which has a rectangular frame having guide members with wheels attached at each corner for engaging the pipes of the scaffold frame. The wheels are attached such that the carriage can ride up and down on the scaffold without interference with the scaffold frame supports and cross members. The carriage has a motor attached to it which is connected to a chain drive. There is a chain which runs through the chain drive and attaches to the top of the scaffold frame. The motor and chain drive act on the chain to drive the carriage up and down the scaffold. The chain drive preferably has a brake for use when the carriage is stopped. The carriage frame has a means of attaching a pair of forks. The width of the forks are adjustable on the carriage frame.

Abstract: A spray pattern analyzer for use in analyzing spray patterns formed by spray nozzles which are attached to an agricultural spray applicator boom. This analyzer includes a corrugated collector tray mounted on a cart. The cart has wheels for moving the collector tray through the spray pattern. The collector tray is designed so as to receive collector test tubes each being longitudinally aligned with the troughs of the collector tray. When the troughs are partially filled with spray, the collector tray is tilted so that the spray will flow into the test tubes to provide a visual indication of the pattern. The collector tray is constructed in segments to allow the collector tray to be collapsed. Further, the cart is constructed to permit an adjustment of the height of the collector tray from the surface upon which the cart rests.
