Abstract: Abstract of the Disclosure A fluid layering device for use with a syringe to facilitate layering a liquid from the syringe onto a denser liquid contained in an open-top centrifuge tube.  A fitting in the device is releasably attachable to the syringe for receiving liquid therefrom.  An elongate nozzle carried on the fitting has a pair of opposed end faces, and a pair of flow-contricting bores communicating associated nozzle end faces with liquid received in the fitting.  An annular step formed on the fitting is engageable by friction fit with the tube's upper open end to hold the nozzle at an axially aligned position within the tube.  At this position, each of the nozzle end faces confronts, and is spaced from, an inner wall portion in the tube by a clearance which is adapted to produce, with liquid being forced from the syringe through the associated bore in the nozzle, a controlled-flow ribbon of liquid down the wall of the tube onto the upper surface of the denser liquid in the tube.

Abstract: ABSTRACT OF THE INVENTION     In the recording/reproducing of digital audio signals, errors are detected and corrected by using two parity words, one arranged at the center of the block formed of data words and the arranged at one end of the block.  The probability that uncorrectable error will be present in the center of the block is relatively high, so placing the parity word there prevents loss of the more valuable data.          Maximum correctable burst errors are determined by the length of the block, so placing the other parity word on the end of the block lengthens it and improves burst error correction.  The parity words are arranged as indicated before adding a cyclic redundancy check (CRC) code to the data signal and then modulation coding the signal before recording.  During playback, the reproduced signal is demodulated and the CRC code used to detect errors for which error pointers are generated.  The reproduced data is read into memories in accordance with generated addresses and the pointers prevent the writing in of words found to be in error, which error words are subsequently corrected if possible using parity codes originally encoded into the signals prior to recording.

Abstract: ABSTRACT    A cam actuated ejector is provided with a shell press having a crankshaft for reciprocating a slide to which die tooling is mounted and having a forming station in which the die tooling forms a part to be ejected.  The ejector includes a kicker bar slidably received within a recess in the press and which is in close proximity to and substantially coplanar with a part to be ejected.  The kicker bar is positively reciprocated by a cam assembly that is synchronously engaged with the crankshaft, which operates the press slide, such that an end of the kicker bar cyclically moves at a first rate of movement from a first position outside the forming station to an intermediate position wherein the end contacts a part to be ejected.  The cam assembly continues to advance the kicker bar at a second rate of movement greater than the first rate from the intermediate position to a second position to eject the part and thereafter the cam assembly rapidly withdraws the kicker bar end from the second position to the first position to clear the die area and to ready it for subsequent cyclic ejection of other formed parts.  The different timed rates of movement of the kicker bar are provided by selectively con-touring the cam surfaces within the cam assembly to contact the part at an optimum speed and to provide positive drive to the kicker bar throughout its cyclic movements.

Abstract: TRACTOR MOUNTED HARVESTER Abstract of the Disclosure A mounting and dismounting system for a rear-mounted cotton harvester or similar implement which permits the tractor to be removed from under the crop receptacle without utilizing a hoist or other large equipment.  By attaching dismounting stands to the rear cross auger frame and to the rear lift frame assembly, the rear basket posts which normally are connected to the tractor axle can be lifted therefrom by extending the hydraulic cylinders connected to the rear lift frame assembly.  The front basket support posts are unpinned from the forward frame of the basket, and as the rear basket posts tilt rearwardly, the basket is lifted to provide clearance in the forward direction.  The tractor can then be driven out from under the basket.  An extension hose is connected to the lift cylinders so that they remain connected to the source of pressure on the tractor as the tractor is driven forwardlly.  Once the tractor has cleared the basket assembly, the front basket posts are reattached to the basket and the pressure in the cylinders is released so that the basket tilts downwardly and rests on the posts for storage.  The procedure is reversed for mounting the harvester.

Abstract: "INTERCRANIAL PRESSURE REGULATOR VALVE"             ABSTRACT OF THE DISCLOSURE         An intercranial pressure regulator valve adapted particularly for the treatment of hydrocephalus and the draining of cerebrospinal fluid (CSF) from a ventricle in the brain to another location in the patient's body includes a movable, flexible diaphragm having first and second surfaces of substantial area which are contacted by the fluid which is being drained and the fluid in the area to which the CSF is to be drained, respectively.  A valve seat on the diaphragm is movable therewith and the valve seat includes a passage for the flow of the fluid which is being drained through the diaphragm.  A ball closure valve is positioned on the cephalad side of the diaphragm.  When the pressure differential on both surfaces of the diaphragm is low, the valve seat flexes into engagement with the ball closure valve to close the passage.  When the pressure differential between these two surfaces increases, the diaphragm flexes in response to the increase such that the valve seat moves away from the ball closure valve to open the passage and drain the CSF from the ventricle to the other location in the body.
