Abstract: ABSTRACT OF THE DISCLOSURE        A gas scavenger system is disclosed for use particularly with anesthetic administering equipment utilizing a demand valve for providing anesthetic gas to the patient. The gas scavenger system includes a collection manifold that collects the waste gases as they leave the normal exhaust ports of the demand valve.  A flexible tubing means then carries those collected gases to a surge chamber prior to eventual discharge into a vacuum system.  The surge chamber provides an interface between the vacuum system and the collection manifold and is connected to the vacuum system through a predetermined sized orifice which limits the flow to the vacuum system to a maximum known flow.  The surge chamber normally allows continuous flow through the orifice to the vacuum system but is sized to accumulate an excess of flow from the collection manifold under abnormal conditions such as is occasioned when a patient coughs to allow time to remove the gases through the orifice and thus to prevent leakage to atmosphere.  The surge chamber itself is directly connected to ambient through a known, fixed resistance such that an excess in pressure in the surge chamber above that determined by the known, fixed resistance is bled to atmosphere.  Thus, in the event of an occlusion in the vacuum line, the patient is always assured a path for exhalation.  Also, in the event the vacuum system draws gas at a faster flow rate than that of waste gases entering the surge chamber from the collection manifold, gas will be drawn from the ambient through the known, fixed resistance.  The pressure is thus controlled at the collection chamber to prevent an excess of either pressure or vacuum from affecting the function of the normal demand valve, yet no moving valves are utilized.  A relief valve is located in the lower portion of the surge chamber to allow runoff of any accumulation of water to prevent that water resulting from condensation from sealing any internal gas passages in the surge chamber.

Abstract: ABSTRACT     In a phototypesetter, an array of light emitting diodes is energized in synchronization with an associated staggered array of fiber optic filaments.  The array of filaments is slanted relative to the direction of movement, and type may be set in both forward and reverse directions.          Type font data is stored in a compressed form in a first microprocessor subsystem.  That compressed data is expanded in real time for each character in a high speed microprocessor subsystem.  Charac-ter image data in the form of character contours is written into alternating RAM groups.  The contour data is then read from the RAM groups on a slice basis and color data is generated.  The alternate RAM groups allow for proper coloring of overlapping character images.  The expanded data is then handled by a logic unit to allow for the staggered fiber optic filaments and for the slant of the fiber optic filament head in both forward and reverse directions.  The data bits for each slice of type is divided into odd and even bytes which are in turn written into and read from a random access memory in a sequence determined by a programmable read only memory.  Memory control bits in the high speed subsystem are obtained directly from a microinstruction memory.

Abstract: TITLE OF THE INVENTION HYBRID EXPANSION APPARATUS AND PROCESS            ABSTRACT OF THE DISCLOSURE     An improved sleeving apparatus and process capable of simultaneously expanding and rolling an interference joint between a reinforcing sleeve and a heat exchanger tube is disclosed herein.          The apparatus generally comprises an elongated housing onto which upper and lower rollers are mounted, and upper and lower hydraulic expanders capable of applying a radially expansive force onto a sleeve across the length of the rollers. The rolls in the rollers are driven by a common drive shaft which is coupled to a hydraulic motor. The apparatus includes a torque controller including a torque sensor and a computer for controlling the torque, and hence the rolling pressure, that the rollers place on the inside surface of the sleeve. The torque sensor is mechanically connected to the output of the driving means of the drive shaft, and electrically connected to the microcomputer. The microcomputer is connected to the control valve of the power supply of the hydraulic motor driving the drive shaft. The torque value programmed into the microcomputer of the torque controller may be chosen so that the rolling pressure exerted by the rolls elongates the metal in the sleeve at the interference joint to the same extent to which this metal is contracted by the hydraulic expanders, thereby resulting in a substantially stress-free joint.

Abstract: ABSTRACT OF THE DISCLOSURE         An ultrasonic wheel probe of the type having a wheel-shaped container with an annular outer surface for rotating about an axis of rotation and rolling upon a specimen to be tested is provided with a plurality of transducers for transmitting and receiving ultrasonic acoustic energy, respectively.  In accordance with the invention, an acoustic barrier is interposed between the transmitting and receiving transducers, and immersed in the coup-ling fluid, so as to isolate the transmitting and receiving trans-ducers from one another.  With this arrangement, echoes emanating from the interface, or surface, of the specimen being tested are prevented from reaching the receiving transducer.  The acoustic barrier is preferably installed on a yoke of the wheel probe so as to be displaceable in a substantially radial direction in response to the contour of the specimen being tested.  The radial align-ment of the acoustic barrier is maintained by a pair of shafts which extend through the yoke and have linear bearings interposed therein.  A resilient element, such as a spring, is arranged to urge the acoustic barrier to its maximum extent from the axis of rotation.  An additional transducer is arranged to communicate ultrasonically with the acoustic barrier so as to monitor its radial location at all times.  The signals produced by this mon-itoring transducer can be utilized to control feedback and gate triggering circuitry.

Abstract: DISPOSABLE WASTE CONTAINMENT GARMENT     ABSTRACT      A disposable waste containment garment which is particularly useful and leakage resistant for bedridden incontinent adults. The garment has side-edge-leakage-guard gutters having closed ends, and longitudinally elasticized distal edges. The gutters and the other garment elements are configured and disposed to substantially obviate inversion or unfolding of the gutters during application and use of the garment. The garment is sized and configured so that, when secured on a user, the elasticized distal edges of the gutters will normally extend along the groin regions of the user, and diverge upwardly across abdominal, hip and lower back areas of the user rather than encircling the thighs of the user. The absorbent core of the garment is preferably sufficiently resilient to cause it to stand away from some lower abdominal and hip regions of the user.   This, in conjunction with the gutters being sufficiently flexible and elasticized, causes adjacent portions of the gutters to be biased open.          These open portions of the gutters are, in fact, reservoirs which substantially obviate leakage by containing free liquid during urination events when fluid is received in the garment faster than it can be absorbed in the absorbent core of the garment, or whenever free liquid is squeezed out of a portion of the garment as when the weight of a bedridden user is shifted. The ends of the gutters in the waistband regions of the garment may be sealed liquid tight, or be secured closed with edge portions of the absorbent core and/or topsheet disposed therein, or a combination of such sealing and securing.
