Abstract: A flow control valve such as a ball valve (12) for controlling fluid flow through a flow line (16). The control valve includes a flow chamber (18), an upstream passage (19), a downstream passage (20), an annular valve body (24), a retainer (26) sealingly engaging the outer annular surface of the flow line and secured to the valve body by a pair of flanges (28), a flow control ball (32) rotatably disposed within the flow chamber for controlling fluid flow through the passages, an operating member (42) for rotating the ball between open and closed positions and means (70) for equalizing the pressure in the valve chamber. The ball includes a centrally bored flow passageway (36) for communicating fluid through the passages and is rotatably supported within the chamber by an annular upstream seat carrier (48) and an annular downstream seat carrier (50). Each seat carrier includes a ball seat (52) positioned within an annular recess (54) provided on the inwardly facing surface (55) of the seat carrier and an O-ring (56) positioned within an annular recess (58) provided on an axially facing surface (59) of the seat carrier. Each seat 52 includes an inwardly facing surface (60) that abuts the outer surface of the ball and an axially facing surface (62) that abuts an axial surface (64) of the seat recess.      The pressure equalizing means includes a passage (72) extending radially inwardly within seat carrier (48) and communicates with an annular groove (73) cut in axial recess (58) and with chamber (18) by an outlet (76) in a recessed portion (82) on an outwardly facing surface (80) of seat carrier (48).  Pressure is equalized when upstream pressure is introduced into chamber (18) inside O-ring (56), through groove (73) and through passage (72). The O-ring in seat carrier (50) seals against ball (32).

Title: Apparatus for enhancing color of gas flames
Inventor: SHIMEK RONALD J
IPC: F24C3/00
Filed: 1994-03-23
Abstract: Method and means for enhancing the visible length and color of high efficiency gas flames in an artificial gas log fireplace/gas burner system is characterized by selecting from a plurality of metallic salt compounds, compounds having a low melting point and the ability to exhibit light in the visible spectrum when the metallic salt compounds absorb energy from a gas flame. The metallic salt compounds are placed in a high temperature area of the burner system adjacent the gas flames so that at the melting point of the metallic salt an ionized vapor is generated which is directed into the path of the combustion air being supplied to the gas burner. The energy level of the ionized metallic salt compounds are elevated and when subsequently cooled, they emit light in the visible spectrum which combines with the gas flames and colors the invisible flame spectrum so that the invisible gas flames become visible and appear longer and exhibit natural colors.

Abstract: A sports ball comprises a hollow spherical-shaped inflatable tube; a covering layer comprising a thin rubber pouch and covering the tube; a reinforced layer which is adhered on the surface of the covering layer with a solution of an adhesive agent and an outer layer formed on the surface of the reinforced layer.  The covering layer is made of a material which does not permit the solution of the adhesive agent to pass therethrough and an inorganic lubricant is disposed between the tube and the covering layer, so that adhesion between the tube and the covering layer is prevented.  A method for making a sports ball includes the steps of: inserting an inflatable tube into a covering layer which comprises a thin rubber pouch and is made of a material which does not permit the solution of an adhesive agent to pass through the covering layer; injecting a powder of an inorganic lubricant into the covering layer; and inflating the inflatable tube into a spherical shape.  A reinforced layer is attached on the surface of the covering layer with the solution of an adhesive agent, alignment guides are formed on the surface of the reinforced layer by molding, and an outer layer is attached on the surface of the reinforced layer along those alignment guides. Alternatively, a method includes the steps of: spreading a powder or a suspension of an inorganic lubricant on an inflatable tube; inserting the tube into a covering layer which comprises a thin rubber pouch and is made of a material which does not permit the solution of an adhesive agent to pass through the covering layer; inflating the inflatable tube into a spherical shape and attaching a reinforced layer on the surface of the covering layer with the solution of an adhesive agent.  Alignment guides are formed on the surface of the reinforced layer by molding, and an outer layer is attached on the surface of the reinforced layer along those alignment guides.

Inventor: FRICK BEAT
IPC: G03B27/73
Filed: 1995-08-14
Abstract: During the processing of an order in a photographic printer, a developed copy film strip can be scanned negative by negative and point-by-point in a scanning station of the printer. From the scan signals, density values for exposure time determination in three partial colors and details on the image field number of the scanned negative can be obtained, and these data are stored in a memory, coordinating the determined three partial exposure times with the corresponding image number. All negatives of the copy film strip are exposedsuccessively on photographic paper on an enlarged scale, using the determined exposure times. In a further step, a number of successive negatives of the film strip are exposed on full-scale or reduced scale in matrix form onto a single sheet of said photographic paper. The image field number associated with each negative is also exposed in matrix form on the single sheet and the exposure data stored from the initial scanning procedure are used as a basis for the exposure of the individual partial images. In addition to the exposures of the negatives, further data in connection with the film strip can also be exposed.
