Abstract: ABSTRACT OF THE DISCLOSURE           A method for applying measured amounts of viscous material in a predetermined pattern in registry to a continuously moving sheet is provided which includes the steps of introducing the viscous material into a rotary valve having a bore in the valve rotor operatively communicative with the fluid inlet, and a passage radially communicating between the axial bore and an opening in the valve seat through which the material is dispensed onto the sheet stock.  The length of the material dispensed to the sheet stock is determined by a slot formed on the surface of the valve rotor which surrounds the opening for the radial passage.  Registry of the pattern is accomplished by correlation of the rotation of the valve with the rate by which the sheet material passes underneath the valve orifice.  The valve containing the slot and related apparatus is also part of the invention.

Abstract: METHOD OF COLOR PRINTING                 Abstract of the Invention A method of providing full range color printing using duplicator technology is disclosed.  The system utilizes subtractive color printing techniques, but avoids the necessity for color masking and generally eliminates color correction as well.   Following exposure of multiple negatives to develop color separations, corresponding printing plates are prepared and developed.  A proofing sequence is optional between the development of the negatives and the plates.  The ultimate printing is achieved by feeding stock into a duplicator which carries each of the three basic negative complementary colors, in sequence; a "black" printer can also be used for a higher degree of contrast and tone.

Abstract: ABSTRACT OF THE DISCLOSURE A copier capable of producing simplex and duplex copies includes an inverter that has constantly rotating input and output rollers mounted for pivotal movement into and out of engagement with a reversibly rotatable sleeve that is mounted on a stationary shaft. When inversion of a sheet is required, a shiftable gate deflects the sheet into a nip formed between the input rollers and the rotatable sleeve. A sensor senses the trail edge of the sheet and through a controller causes a reversible drive motor to pivot the input rollers out of engagement with the sleeve while simultaneously placing the output rollers into driving engagement with the sleeve. The sheet is then driven by the output rollers out of the inverter and back into the paper path of the copier for further processing.

Abstract: Abstract Method and apparatus for ultrasonic non-destructive testing by the pulse echo method.  The pulses received from flaws in a test object are supplied to a main branch circuit for amplification to produce a suitable flaw display and to a back echo branch circuit having a lower amplification such that the back echo signal does not saturate the amplifier.  During a "flaw gate" period, the output from the main branch circuit is supplied through a high speed electronic switch to a display.  At the conclusion of the flaw gate period, the switch is actuated to supply the back echo branch circuit output to the display.  In this manner, the back echo signal may be monitored for additional flaw information.

Abstract: ABSTRACT OF THE DISCLOSURE        A self-storing, inflatable pool cover designed to float to the surface of the pool when inflated and form over this surface an insulating air dome, and to sink to, and spread over, the bottom of the pool when deflated.  This pool cover comprises a plastic membrane shaped to substantially conform with the  inner periphery of the pool and ringed by an endless, peripherical tube provided at one side with at least one bleed hole opening onto the bottom of the membrane, and with an air intake at the other side opposite to the one side.  An inflatable bladder is fixed slightly off center onto the membrane.  A closable air-vent is connected to the membrane near the bladder, and an air-line connectable to a compressed air supply is provided to supply air to the spout of the bladder and to the intake of the tube in this order.  In use, connection of the air line to the air supply while the air vent is closed causes the bladder to inflate and to raise the center of the membrane in such a manner that this membrane may trap the air subsequently forced by the air supply through the endless tube and the bleed hole.  This raises upwardly from the bottom of the pool until it floats to the surface of the same.  In contrast, opening of the air vent while the air line is disconnected from the air supply, causes the trapped air to escape, the bladder to deflate and the cover to sink to the bottom of the pool.
