Abstract: ABSTRACT OF THE DISCLOSURE       This equipment is of the type comprising a spray gun provided with a hydrostatic atomizing nozzle delivering a flat jet of liquid in combination with a pair of orifices disposed on either side of the nozzle and symmetrically in relation to the flat jet of liquid so as to deliver air jets in a plane perpendicular to that of the flat jet of liquid.  The front surface of the nozzle is frustoconical and the two orifices are adapted to direct the air jets against said frustoconical sur-face and thus create two fan-shaped sheets of compressed air on either side of the flat jet of liquid also of fan-like configuration, said two fan-shaped sheets of compressed air being somewhat wider than the jet of liquid and meeting together at their edges while clamping said liquid jet.  The equipment further comprises means for varying the pressure of the paint or other product from 5 to 30 bars (72.5 to 435 lbf) and the air jet pressure from 1 to 4 bars (14.5 to 58 lbf).

Abstract: SHEET HANDLING APPARATUS   ABSTRACT OF THE DISCLOSURE An apparatus for transporting a sheet of a flex-ible material between a first and a second position.  The apparatus includes and elongated frame and an air-previous endless belt movably mounted on first and second pulleys positioned at each end of the frame.  The belt has its upper rung travelling from the first pulley, adjacent the first position, to the second pulley, adjacent the second position, and is arranged to receive a lead strip of the sheet from the first position.  A vacuum chest having a perforated top extends longitudinally of and below the upper rung of the belt.  There are means for evacuating air from the chest in order to apply a vacuum at the undersurface of the belt and thereby cause the lead strip to cling to the belt.  The apparatus has means defining an opening where the sheet leaves the belt and an air is directed contrary to the through the opening.  The air is directed contrary to the direction of movement of the belt and with a velocity suffi-cient both to overcome any gripping effect air entrained within the air-pervious belt and to lift the sheet of flexible material.                   - i -

Abstract: The present invention is directed to an improved bidet toilet seat adapted to be mounted on a toilet bowl in place of a conventional toilet seat.  Prior art bidets are traditionally separate from the conventional toilet. Attempts have been made to provide an automatic washing apparatus built into a conventional toilet seat but they have proven to be too messy or ineffective. The present invention overcomes the disadvantages of the prior art by providing a toilet seat having an antisiphon bidet nozzle, an antisiphon vaginal wash nozzle, and the toilet seat forming housing for receiving a deodorant container, a warm air blower, a water heater, a manually accessible pressure regulator, a medication container, and appropriate manually operated valve and switches for supplying water to the bidet and vaginal nozzles, and actuating the blower, the toilet seat having an adjustable mounting means for attachment to the toilet seat mounting means of a wide variety of toilet bowls.

Abstract: ERROR RECOVERY AND CONTROL IN A MASS STORAGE SYSTEM Abstract A virtually addressed multilevel mass storage system (MSS) has error recovery and definition procedures and apparatus for controlling and enabling recovery from error conditions in an upper storage level.  A plurality of possible error conditions in an upper level gives rise to errors in destaging data signals to a lower level, plus possible overwriting good data with data in error.          A first such error condition is a data error detected during a destage.  A second such error condition is repeated upper-level equipment (not data) errors.  Both errors make data integrity of the lower-level suspect.   Corrective action for a plurality of errors includes co-ordination with a host computer, reconfiguration, destaging data in error after precautionary steps, and preserving data in error at the failing upper level unit which is used in virtual mode except for the portion yielding the error condition.

Abstract: ABSTRACT OF THE DISCLOSURE            The nozzle includes a sleeve and a hollow body concentrically disposed within the sleeve. A hollow cylindrical baffle housing is coaxially maintained within the body by vanes which extend between the housing outer wall and the body inner wall. Formed on the outer wall of the body is a thread which mates with a thread on the inner wall of the sleeve to permit rotation of the sleeve relative to the body between two stop positions. A baffle is secured to the baffle housing and is provided with a head which, as the sleeve is rotated toward the first stop position, approaches a baffle seat formed on the sleeve and thereby diminishes the quantity of liquid discharging from the nozzle.   The sleeve is prevented from being rotted beyond the second stop position by two alternative modes:  the female thread at its trailing edge is provided with an end wall which is disposed normal to the adjacent side walls of the thread and which, when the leading edge of the male thread is advanced  into contact therewith prevents further advance of the male thread.  Alternatively, the trailing edge of the male thread is provided with an enlarged portion which jams in the female thread when the sleeve is in the second stop position and prevents further rotation of the sleeve.

Abstract: A METHOD OF MAKING A COFFEE EXTRACT          Abstract of the Disclosure An improved coffee extract is prepared by subjecting roast and finely ground coffee particles of 5-800 microns to a slurry extraction operation which employs moderate temperatures  and low shear gentle agitation to negotiate the extraction of high quality soluble coffee solids there-from without forming emulsions caused by released coffee oils and excessive agitation.  The extract is separated from slurry insolubles to yield 18% - 27% soluble coffee solids based on the dry weight of the roast and ground coffee charge.  This extract provides the basis for an improved instant coffee.
