Title: Separator drain boxes
Inventor: MAVROS STRATOS
IPC: B01D45/18
Filed: 1985-12-11
Granted: 1991-04-16
Abstract: P.14 ABSTRACT Separator Drain Boxes It is common for engines of the gas turbine variety to have filters at their air intakes.  An example of a system employing such a filter takes the form of a tube or duct into which is drain the air to be filtered, which tube contains a number of filtering components including pads of knitted mesh and a series of zig-zag vanes.  These vanes remove any entrained water droplets, and the "condensed" water runs down the vanes (under gravity) into what is known as a "drain box", from which it is led away and disposed of.      The present invention proposes a novel design of drain box; instead of having the vanes bottom on a ledge in the drain box, above the drain box floor, leaving a gap between the bottom of the vanes and the floor of the drain box, and so allowing re-entrainment of the moisture, the present invention proposes that the vanes be extended to the floor of the drain box in intimate contact with the drain enclosure bottom surface.  In addition to preventing re-entrainment, extending the vanes in this way provides additional structural vane support, and results in a stronger, more rigid filter system.

At least 90% of the pellets in the silicon carbide media have a specific gravity (density) greater than 3.05 g/cm3.    The invention includes the unique media, which may be used for various grinding operations,  and includes unique milled powders.  One of the unique powders has particles which have an average length to width ratio of greater than 2.5.  Another of the unique powders is black silicon carbide containing, from 200 to 2,000 parts per million of aluminum in solid solution.

Abstract: ABSTRACT           The placing of an artificial intraocular lens device (IOL) in the anterior chamber of the eye (in front of the iris) for treating myopia.  The intraocular lens device includes a meniscus style lens which has a plano anterior surface and a concave posterior surface. The edges of the lens are rounded off and the peripheral portion of the lens is considerably thicker than the central portion of the lens.  The lens is a minus (negative) refracting lens.  The lens is suspended in the anterior chamber by three or four carrying angles or haptics having solid footplates at their ends for anchoring the device in the anatomic angle of the eye.  The solid footplates are sized to prevent tissue overgrowth and resulting synechia after placement, additionally facilitating subsequent removal of the lens device from the anterior chamber if necessary.  A ridged lens glide is also provided to facilitate insertion of the lens device into the anterior chamber during implantation.          This lens device is utilized in the phakic state (the state of the natural lens being retained).  With the patient's natural crystalline lens being retained, the natural crystalline lens is located in the posterior chamber behind the iris and the artificial intraocular lens of negative power is located in the anterior chamber in front of the iris.  The presence of the phakic state allows for accommodation to occur.  The intended age range for applicability of the device is approximately from age 20-50.
