Abstract: ABSTRACT A whirlpool bath designed for use in hospitals and similar institutions has a tub which is raised sufficiently above the floor level on a recessed steel base so as to allow a vertical clearance for the use of trolleys and mobile patient-handling equip-ment to move patients toward and lower patients into the whirlpool bath.  The recess also makes work around the tub easier for attendants, providing toe room allowing the attendants to move closer to the tub. Bumper strips and base moldings are attached to the whirlpool bath to protect the bath from damage from movable patient-handling equipment.  The sides and ends of the tub have removable panels fitting under the rim of the tub and clipping to a steel frame for rapid and easy removal and replacement.  A capped opening in the built-in plumbing allows the water supply from a wall-mounted mixing valve to be admitted directly to the tub through the whirlpool fittings as an alternative to a spout or hose.

Abstract: ABSTRACT MONITORING GASES An adsorptive trap for monitoring gases and/or vapours comprises a tube (e g. length about 4-8 cm, internal diameter about 3-5 mm) packed with one or more suitable adsorbents in appropriate amount (e.g. about 0.5 g), each adsorbent being held packed in place between a pair of rigidly fixed porous discs e.g. porous sintered powder or metal gauze or mesh discs.  It has been found that these adsorptive traps provide improved accuracy and precision of measurement as compared with prior art traps in which the adsorbent is relatively loosely packed and retained in the tube. A preferred method of fabricating the traps makes use of thermal contraction and expansion by allowing a previously cooled, contracted, oversize disc to be loosely fitted within the tube and expand on warming to ambient temperature and thereby become rigidly fixed in place.

Abstract: ABSTRACT   An echo canceller eliminates undesirable echo appearing in a long distance digitized telephone network of the type in which incoming and outgoing digital signals have mutually different sampling rates.  The echo canceller com-prises a sample interpolator for converting the incoming digital signal into one having the same sample rate as the outgoing digital signal.  An echo estimator responsive to the output of the sample interpolator produces an estimated echo signal to cancel by subtraction the echo signal present in the unprocessed digital signal.

Abstract: BF&N 6991 VENEER LATHE SCANNING SYSTEM   Abstract of the Disclosure A  pair  of  sonic  transducers  are mounted above a peeler  block on a veneer  lathe,  adjacent opposite ends of the block.  Bursts of sonic energy are directed downward to strike the surface of the block such that sonic energy is reflected from the block surface to the transducers.  The distance from the transducers to the axis of rotation of the lathe spindle upon which the block is mounted is known and,  as  a consequence,  the  radius  of  the peeler block may be determined in response to the ultra-sonically measured distance from the transducers to the block surface. A series of radius measurements may be made as the block is rotated on the lathe spindle.   Additionally,  measurements may  be  made when a log is first loaded onto the lathe, after the log is rounded up, and after peeling of the block is completed.

Abstract: BLIND FASTENER DEVICE            Abstract of the Disclosure A blind fastener assembly for securing together panels or sheets of material which may have the same or different hardness and thickness and also for attaching articles to panels or walls of relatively soft material. The assembly includes a hollow rivet body having a fixed head portion at one end and longitudinally separable and spreadable sectors formed by axial slots at the opposite end of the rivet body.  An elongated pin located within an axial cavity of the rivet has an enlarged tapered end portion.  Between the pin end portion and the opposite end of the rivet body is a deformable sleeve member adapted to bear against the inner end of the rivet. Axial pulling force on the pin causes its tapered end portion to compress and deform the sleeve against the inner slotted end of the rivet body and ultimately causes its longitudinal sectors to spread apart.  Continued pulling force causes the deformable sleeve to enlarge in diameter so as to press the separated body portions firmly against the surface surrounding the rivet, thereby anchoring it in place.
