Abstract: This relates to the provision of the pour spout portion of a blow molded plastic bottle with a dripless lip. In one form, the terminal end of the pour spout is internally reamed at an angle so as to terminate in an exterior sharp edge, after which the resultant tapered end portion of the pour spout is engaged by a rotating tool which frictionally heats the plastic engaged thereby and progressively turns over the sharp edge through an angle on the order of 180.degree. to provide the desired dripless lip. In another form, the pour spout portion of the container neck finish is provided with an integrally molded outwardly directed hollow rib which lies in a sloping plane. The rib extends only partially about the circumference of the pour spout. The pour spout is then trimmed at an angle to the axis of the pour spout and parallel to the plane of the rib so as to provide for a pour lip of limited circumferential extent and which pour lip, depending upon the plane of trimming may terminate in a sharp dripless lip.

Abstract: A clean box in which the rubber arms and hands may slide laterally relative to the remainder of the box. A first rigid plastic sheet has ovals passing through it. A second rigid plastic sheet, in front of the first, has circular openings on which the rubberized arm and hand gloves attach. The circular openings' diameter approximately equals the smaller dimension of the ovals on the first sheet of plastic. Resin strips provide an air seal along the upper and lower edges of the sliding first sheet of plastic. Wiper blades attached to the edges of the moving sheet complete the seal between the two sheets of plastic. A worker, with his hands and arms in the gloves and needing to reach a distant point in the clean box, may simply push against the edge of the openings for the gloves. The sheet of plastic will then move in the direction in which pushed. The clean box may have entirely rigid transparent sides to allow for a clear view.

Abstract: A vial washer in which the vials follow a serpentine path through several stages of cleaning. A sheet having the serpentine path in the form of an elongated slot guides the vials through their washing. Conveyor belts moving in opposite directions underneath the elongated slot move the vials in the directions through the equipment. The conveyor belts have an open grid allow for the passage of the cleaning liquids through them. The sheet with the cut-out slot may be replaced with a similar sheet with a different width of opening for bottles of differing sizes. The cleaning may include one or more stages of a detergent wash, water rinse, and air and vacuum drying. Slight deviations in the straight sections of the elongated slot will cause the vials to rotate so that all sides become clean.

Abstract: A cleaner for removing particulate matter on bottles moving on a conveyor line. As the bottles move along the conveyor, they contact brushes in the form of continuous, endless belts. The belt has motion relative to the bottles which it contacts. Preferably, the belt moves in the same direction, but faster than, the bottles. On the other side of the bottles, a screw auger having spaces large enough for the bottles to fit in may assure the correct motion of the bottles. Alternately, a brush also in contact with the bottles and on the other side of the belt brush may also help assure the proper cleaning of the bottles. The second brush may take the form of a rotating cylinder, a rotating auger formed of brush bristles, or even a second endless, continuous belt brush.

Abstract: Optical components and methods for an I.V. flow detector providing complete coverage of a drip chamber through the use of a single emitter and receiver. The optical components take the light of a single emitter and spread it uniformly across the entire drip chamber. Furthermore, the light is collimated as it passes through the chamber. In addition, the optics collimates the light at some point in its path from the emitter to the drip chamber. Similarly, it collimates the beam of radiation at some point in its path from the drip chamber to the receiver. Further, the optics creates a plane of symmetry for the light path passing through the center of the drip chamber and lies perpendicular to the path of the light. The design specifically takes into account the optical characteristics of the drip chamber itself.

Abstract: A drop detector for intravenous systems in which an infrared emitter is pulsed at 10 kHz. The pulsed radiation passes through a drip chamber and then to a detector. The detector circuit determines the amplitude modulation of the 10 kHz. carrier frequency. This provides an indication of when the drop falling through the drip chamber has interrupted the light beam. An automatic gain control circuit maintains the output of the detector, on a long time constant basis, at a constant level to eliminate the vagaries of drip chambers with different optical characteristics and the like. When the AGC circuit lacks the ability to maintain the output of the detector circuitry at a constant level, a fault detector provides an alarm to indicate that the circuitry has exceeded its operational range.

Abstract: A housing for a laptop computer or computer terminal and the computer and terminal themselves in which opening the top causes a curved surface to descend below the computer's rear, bottom surface. This ridge runs across at least half of the bottom of the computer's back and preferably the entire computer. It serves to support the bottom section of the cover, and thus the keyboard, when used on a person's lap at a suitable angle. Specifically, it elevates the rear of the keyboard so that the hands have facile access to all the keys. The curved surface is formed integrally with the edge of the computer cover's upper section. When the top closes, the surface moves to a position where it does not descend below the bottom of the cover in order to provide a neat, portable package. Opening the top causes the surface, or ridge, to occupy the position where it will sit on the person's legs to prop up the keyboard.

Abstract: This relates to the provision of a container having as an integral part thereof a separate pickup tube so that the neck finish of the container has the usual mouth together with a pickup tube mouth. A conventional spray pump has the vent and pickup passage portion thereof replaced by a replacement assembly which will interlock with the container neck finish between the two mouths in a manner to orient the pump with respect to the container. The replacement assembly includes a combined vent and pickup member and a separately formed backup disc which are interlocked relative to one another for selectively positioning the backup disc with respect to the combined vent and pickup member and thus with respect to the pump. The backup disc, in turn, has projecting legs which interlock with the container neck finish. The backup disc has several possible positions with respect to the combined vent and pickup member.

Abstract: An oval mat cutter allows the continuous adjustment of the overall size of the oval as well as the difference between its larger and smaller axes. The cutter may also produce circles. The cutter separates the knife from a first point which it keeps in a first groove. It separates this first point from a second point which it keeps in a second groove lying perpendicular to the first. A generally circular motion of the cutter while maintaining the two points in their respective grooves creates the desired oval. Making the two points in their respective groove coincide with each other will result in the production of a circle. The knife that makes the actual cut sits next to a wheel whose outer circumference has a sharp ridge. The knife has configurations where it extends to various distances beyond the edge of the wheel and one in which it sits within the wheel's circumference. To make a clean cut, the wheel, with the knife retracted, makes a groove in the mat.

Abstract: Waistband interlinings are made by ultrasonically cutting a fabric having warp yarns and fill yarns of a thermoplastics material along lines parallel to the warp threads. An acrylic finish on the fabric permits it to undergo the ultrasonic cutting, will retard the development of brittleness in the fused fibres, and keep the resulting fused edge intact. The fabric should have at least 30 fill yarns per inch but no more than 42 warp yarns per inch. The fabric is cut by passing it between a stationary pressing element, or knife, and the horn of an ultrasonic generator. The fill yarns melt as they pass between the knife and the horn and fuse into adjacent fill threads to form a continuous edge along the length of the cut fabric. The resulting waistband material has a smooth edge formed from fill, or weft, fibres fused to each other and to not more than one warp thread. The waistband interlining finds use in a waistband assembly for slacks and pants.

Abstract: A spooling apparatus attachable to a printing press and operating under pneumatic control and power. An elongated web passes through a linear slitter, over a unidirectional roller, and onto a take-up spool. The spool rotates on power received through a belt drive and a variable speed gear box from the press itself. Upon the receipt of a signal from the press, a pneumatically controlled and powered knife cuts the web and urges it onto another spool. A spring dampener keeps the knife from bouncing and produces a clean cut. When the knife returns to its original position, the pneumatics applies a brake to the full spool to stop its rotating and allow the operator to remove the spooled web. The pneumatics then lifts a cam follower from a stop in a cam and engages a clutch to rotate the frame which holds the rollers for the spooling. This brings the filling spool to the location previously occupied by the full spool. There it continues to rotate and take up the web.

Abstract: A pocket for a garment adapted to removably receive an object having appendages partially visible therein, wherein the pocket is a panel of flexible yieldable material which has a top and sides, with openings therethrough, and the object may be inserted into the pocket with its appendages extending through the top and a side opening. The pocket may have a bottom side parallel to the top side and opposed parallel sides and tapered sides between the parallel sides and bottom side, and openings through the tapered sides. The garment may have graphic indicia arranged on it and the object, when secured in the pocket, forms a part of the graphic indicia.

Abstract: Improvements for an incinerator system including double reburn tunnels, an excitor within a reburn tunnel, a choker for closing off part of a reburn tunnel, a grate near the incinerator's inlet to permit the drying and initial combustion of refuse, an ash scoop which remains out of the water during most of its operation. The use of dual reburn tunnels, along with a damper that permits the closure of at least one of them, permits the efficient and environmentally acceptable utilization of the main incinerator chamber even with minimal refuse contained there. With less refuse, only one reburn unit operates; it will still have sufficient heat and throughput to maintain, with minimal auxiliary fuel, the temperatures needed for complete combustion. An excitor, or solid stationary object placed within the reburn tunnel, permits the retention and reflection of the heat generated by the burning to assure complete combustion of all hydrocarbons within the reburn unit.

Abstract: This relates to a labeller for applying simultaneously two labels to a dual cavity mold half. The labeller is especially constructed to receive a pair of labels from a pair of adjacent label magazines and then move one of the labels towards the other so as to reduce the overall width of the pair of labels. This permits the pair of labels to be moved between a pair of mold halves within the limited space available and thereafter be rotated for alignment with the dual cavities of the mold half for positioning within the dual cavities. Basically speaking, the labeller includes a support member having mounted thereon a pair of carriers for separate movement towards and away from one another. The carriers are moved such that one normally remains fixed after a label is picked up by pickup heads carried thereby while the other carrier is moved towards the first carrier so as to move the labels together.

Abstract: A valve assembly which may be incorporated in a pump and container arrangement so as to permit the dispensing of liquid from the container when the container is in an inverted position as well as when the container is in its normal upright position. The valve assembly is primarily formed by a disc which has formed as part thereof a valve unit. The valve unit, in turn, is provided with a vent passage therethrough which is normally closed in the inverted position of the unit and a liquid passage which is normally closed in the upright position of the valve assembly. The liquid passage is opened by the weight of the liquid within the container on the ball check valve thereof when the container is inverted.

Abstract: Resin-coated bottoms of pockets to provide extended life for the porous material. Coating one side of the pocket bottoms provides enhanced abrasion resistance and reduces seam slippage along the stitching on the pocket's bottom. The resin may include a polyurethane or a polyacrylate, with a polyester polyurethane combination finding particular utility. The resin fills many of the pores of material, but leaves others open. The open pores avoids perspiration and other moisture from adhering to the wearer's skin. Coloring the resin helps identify the resin's presence as well as providing an indication of origin for the garment or pocket itself. Typically, the only manufacturing of the pocket includes coating one side of the pocketing material with the uncured resin. The compound embedded on one side of the material then undergoes curing, generally through the application of heat, to form a coherent substance and open the pores.
