Abstract: FLUID ABSORBENT QUANTITATIVE TEST DEVICE Abstract An absorbent quantitative test device in the form of a flat patch.  When placed on the skin of a subject, the device collects a fixed volume of sweat.  It is particularly intended to be used in screen testing for cystic fibrosis by measuring the chloride level in sweat and providing a visual indication when the level is in excess of a predetermined concentration.  A fill tab indicator undergoes a color change when the fixed volume of sweat has been collected signifying comple-tion of the test.   The device includes two concentric circular reaction areas of chemically treated absorbent paper or the like.  The sweat sample is introduced into the device at the center of the first or inner circular reaction area which contains a chemical composition capable of reacting with all chloride in the sweat sample below a predetermined concentration value to screen out that amount of chloride.  A second or outer ring-shaped reaction area contains a chemical com-position which indicates a color change for any chloride reaching it in excess of the predetermined concentration value.  The color change in the outer ring-shaped portion thereby provides a quantitative indication of the presence of a concentration of chloride in the subject's sweat in excess of the prede-termined concentration level.

Abstract: LIGATING CLIP CARTRIDGE            Abstract A multiple clip applier including a handle and a cartridge which holds a large number of ligating clips and which snaps into a cartridge-receiving channel on the handle. The handle operates like an elongated scissors with scissors handles at one end and jaws at the other to which clips may be delivered in rapid succession.  Opening and closing the scissors handles operates the mechanism of the handle to open and close the jaws and to provide a long stroke motion for delivering clips from the end of the cartridge to the nose section.  Clips may be indexed through the cartridge by reciprocating parts of the cartridge with respect to one another with a short stroke cocking motion captured from the long stroke delivery motion from a cooperating slot and pin mechanism.  These two motions are accomplished within the envelope of motion of the normal opening and closing of the scissors handles to operate the jaws of the applier and to feed and index clips from the cartridge to the nose.  The mechanism of the present invention permits the overall shape of the handle to be small, compact and readily adaptable for use even deep in an incision site.

Abstract: "Error-Correction System For Two-dimensional Multilevel Signals"                         ABSTRACT       Disclosed is an error correction system in which part of the data bits of first multilevel input data is differentially encoded to form second data comprising the differentially encoded data bits and the remainder data bits and converting the bit patterns of the second data into third data in two-dimensional multilevel signal space according to a predetermined transfer function.  A transparent error-correcting code is derived from each of the different phase of the third data and appended to each different phase to thereby form fourth data which is then modulated upon a carrier in two-dimensional multilevel signal space for transmission to a receiver where the signal is demodulated to recover the fourth data.  The appended error-correcting code is separated from each different phase of the fourth data.  An error which might exist in the received data is corrected by the separated error-correcting code in respect of each phase.  The bit pattern of the error-corrected data is reconverted to recover the original second data.  One of the phases of the second data is differentially decoded to recover the original first data.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a compact automatically operating distillation apparatus comprising a baseplate that will free-stand, but is more usually located on a reservoir to receive the distillate, which usually is water.  A boiler container having an electric heater is removably mounted on a support, which is movably mounted on the baseplate with the weight of the container and the water opposed by a spring.  The support operates electric switches that open a solenoid-operated valve to supply water to the boiler when its weight decreases a predetermined amount, and that will switch off the heater if the boiler has insufficient water.  The output of the boiler goes to a condenser coil which is supplied with cooling air by a fan, the operation of which is similarly controlled.  A float in the reservoir controls another switch that will stop operation when the reservoir is full.

Abstract: ABSTRACT           Apparatus for accumulating stacks of superimposed layers or piles of paper sheets has a horizontal platform which receives successive layers from a feeding unit and can open up to permit the properly oriented layer thereon to descend by gravity onto an elevator which is disposed at a level below the platform and at a distance only slightly exceeding the height of a layer.  The elevator is then lowered by a step, and the platform receives and discharges the next layer in the same way so that the elevator supports two layers.  The accumulation of layers on the elevator is repeated as often as desired in order to accumulate a stack of desired height.  The elevator is then opened and permits the fully grown stack to descend through a chute and into a container (such as a carton which is disposed therebelow and is properly centered by a suitable receptacle).  The descent of the stack is braked by the column of air which is pushed by the stack in front of it through the chute and into the interior of the carton.  The platform comprises two panels which are movable laterally away from each other to permit a layer to descend from the platform onto the elevator or onto the topmost layer on the elevator.
