Abstract: Improvements for hydronic air separators enable removal of micro bubbles of the air and micro particles of dirt. Adding coalescing media (CM) to existing and new tangential and in-line AS helps remove damaging micro air bubbles and small dirt particles from the water by a physics principle called surface adhesion. When the small air bubbles and dirt in the water come in contact with the CM, they stick to the surface of the media and then coalesce into larger bubbles and clumps of dirt. The larger air bubbles can float up off the CM and out of the water, to be released from the AS though an automatic air release valve. The larger dirt clumps fall off the CM and land at the bottom of the AS tank where they can be expelled through a hole in the AS tank connected to a drain valve. Water can be filtrated leaving the top of a separator tank. In such arrangements, material in the water with a specific gravity lower than 1.

Abstract: A light wave rangefinder includes a light transmitting optical system for directing a laser pulse at a target, and a light receiving optical system for receiving reflected light from the target, including a Geiger-mode avalanche photodiode (APD) array and a non-imaging optical device. The non-imaging optical device is positioned between the received reflected light and the APD array, and is configured to uniformly distribute the received reflected light across the APD array. The APD array is uniformly illuminated by a single received reflected laser pulse, producing a plurality of Geiger-mode avalanche events.

Abstract: The present invention comprises a novel apparatus for the cleaning of an ostomy bag being worn by an ostomy patient. The cleaning apparatus of the invention is configured in three embodiments capable of fixed installation, portable use and bedside use, respectively. The apparatus of the fixed and portable embodiments provides a support for a patient at a sufficient height above a toilet bowl in the form of a platform having support bars with security stops and a chute removably hung from said platform to discharge excreta into the bowl. The fixed embodiment employs a hose for attachment to house water supply and a nozzle adapted to clean within the ostomy bag. The portable embodiment employs a reservoir which supplies pressurized water either by elevation or by use of a portable pump. The convalescent embodiment is adapted to be used at the bedside and has a fluid reservoir/portable pump, hose and a collecting tank, such as a bedpan mounted to receive the excreta being cleaned from the ostomy bag.

Abstract: A printing apparatus includes a rotatable anilox roll engageable with a rotatable print cylinder for transferring ink thereto. A rotatable wipe roll and a doctor blade head are selectively engageable with different portions of the anilox roll to provide alternative wipe roll and doctor blade inking systems. Preferably both inking systems have substantially common ink supply and ink return paths with a valve being selectively operable to direct the ink supply path to either the wipe roll or the doctor blade head. Facilities for effecting a wash cycle may be provided to wash either inking system after use. Preferably an interlock arrangement prevents changing in use between the two inking systems until a wash cycle has been completed.

Abstract: A rotary die-cut apparatus, in which a die roll cooperates with a resiliently covered anvil roll for die-cutting carton blanks passed therebetween, incorporates a constant mesh gear train between the die roll and the anvil roll for providing an infinite hunting ratio between the rolls. This provides more uniform wear of the anvil roll cover and prolongs its effective life. Preferably, this gear train includes a harmonic drive having a wave generator cam rotatable by a trim motor. An arrangement for sensing changes in diameter of the anvil roll due to wear of its cover may provide an input for determining the speed of the trim motor. A resurfacing mechanism for removing the outer surface of the cover when worn may provide this input. A pulse generator is preferably incorporated in a controller of the trim motor for periodically making random changes in the speed of the trim motor.

Abstract: Apparatus and method for cutting an end portion of a carton blank, e.g. to form a stitch flap, employs a rotatably driven male cutting head cooperating with a rotatably driven female cutting head. The female cutting head has a peripheral cutting groove therein and an anvil surface adjacent one side of the groove. The male cutting head has a two edged slot cutting blade of predetermined arcuate length which enters the groove each revolution, and a knife which extends transversely away from the blade and engages the anvil surface each revolution. The blade has a scallop-like cut-out in the side adjacent the anvil surface. The cut-out modifies the blade to a single edged cutting blade for a small part of its length. Scrap portions produced from the carton blank by a slotting cut of the blade and a transverse cut of the knife are integrally connected together by a bridging piece enabled by this cut-out.
