Abstract: A method and apparatus for assembling a spool valve into a valve bore of a body by providing compressed gas to the valve bore at a pressure below the pressure of compressed gas supplied to a passage within a carrier body containing a spool valve substantially concentrically aligned with the valve bore to advance the spool valve from the passage into the valve bore. The compressed gas in the passage provides a force acting generally uniformly on the spool valve substantially concentrically aligning the spool valve within the passage. The compressed gas supplied to the valve bore also acts substantially uniformly on the spool valve tending to substantially concentrically align the spool valve within the valve bore when the spool valve is advanced therein. While the gas in the passage and the valve bore align the spool valve, the higher pressure of the gas in the passage advances the spool valve into the valve bore.
Abstract: An apparatus is provided for the removal of "trims" and other waste from small rolls of toilet paper, all-purpose wipers and other articles, with arrangement for thrust-operated advancement of rows of said small rolls (R). It includes at least a continuous belt element 12, with a suction box 30 able to hold the small rolls (R) in suspension and to move the latter forward, while excluding the "trims" (RF) or other scraps from this action. The continuous belt element 12 has uniformly distributed apertures (22) and, in its lower active travel portion, moves at a speed at least equal to the average feeding speed of the small rolls. It slides beneath the suction box 30 which exerts a pneumatic aspirating and retaining action on the row of advancing small rolls.
Abstract: A seamless belt is fabricated by application of a coating to an endless substrate. The substrate is elastically stretched over a hollow cylindrical elongated support mandrel. The mandrel is formed of a porous material. Fluid is applied under pressure through the mandrel to form a layer of fluid between the outer surface of the mandrel and the inner surface of the substrate. The flow of fluid is manipulated to axially displace and to rotate the substrate on the outer surface of the mandrel. The flow of fluid is manipulated to orient a selected portion of the surface of the substrate to an angle to a direction of application of a coating. The temperature of fluid is manipulated to assist in substrate temperature control at steps of the coating and drying process.
Abstract: A media transport mechanism including a high accuracy vacuum belt used in conjunction with a pinch roller assembly. The media transport mechanism includes a vacuum belt supportably wrapped around two sprocket assemblies and a plenum and disposed in facing relation to a print head. The vacuum belt has two pinch roller assemblies disposed in spaced-apart relation across the front surface of the vacuum belt, with each pinch roller assembly including two pinch rollers which, in conjunction with the vacuum belt, grip and advance a sheet of media across the front surface of the vacuum belt during printing. The plenum provides a vacuum hold-down force for holding the media flat against the front surface of the vacuum belt.
Abstract: An apparatus for bonding a multi-layer thin film onto a substrate and for removing a layer of the film. A printed circuit board having a multi-layer film bonded to a planar surface thereof has one layer of the film lifted at a leading edge by vibration and fluid pressure. The leading edge is mechanically gripped and a pulling force applied thereto to draw the film from the surface of the circuit board and to transfer the removed film along a path to a discharge apparatus. The transfer apparatus includes frictionally engaged belts which direct the film along a transfer path to a source of ionized fluid which is applied to the film in order to remove static and direct the film along the transfer path towards a used film receptacle.
Abstract: A process for coating wet rubber pellets including coating the pellets with an inorganic partitioning agent, a thickener and binder, and an anionic water soluble dispersant, air conveying the pellets to a dryer, and compressing the pellets to form a bale. By virtue of the coating, the bales are rendered more friable.
Abstract: A web of paper, cardboard, foil or textile material is pulled against and between two rotary knives which sever the web longitudinally and form a slot as well as dust. Such dust is removed by a pneumatic mechanism having one or more nozzles which discharge one or more streams of compressed ionized air against the upper side of the web in the region of the slot, and a suction chamber disposed beneath the path for the web, extending across the slot beneath the nozzle or nozzles, and having one or more suction ports which enable the chamber to collect the particles of dust. The port or ports further enable the chamber to collect those fragments of the web which adhere to the separated sections of the web in the region of the slot between such sections.
Abstract: A method and apparatus for collecting dust and particles produced in machining a workpiece. The method and apparatus uses a shroud formed by a pair of frusta-conical walls spaced apart from each other to define an annular air passage therebetween. The shroud is mounted so that the machine tool extends through a central opening formed in the shroud. The annular air passage has an upper air inlet intersecting the air passage with a cylindrical component and a lower air outlet facing inwardly toward the machine tool. Pressurized air flows into the air passage and is thus directed from the air outlet toward the machine tool in a swirling manner. At the same time, a vacuum withdraws air from within the shroud to collect dust and chips produced by the machine tool.
Abstract: A device is provided for automatically inspecting a fastener for defects prior to its installation in an assembly operation. The fastener is propelled by air or gravity along a feed line. The inspection device is connected in the feed line and has a cam member that is positionable into the fastener's path of travel for blocking it at a certain position. A television camera produces a video image of the stopped fastener, which shows the fastener's actual dimensions. A computer then compares the actual dimensions with the fastener's desired, which are prestored in the computer's memory. If the two substantially match, the fastener is known to be acceptable for installation.
Abstract: A system and method for efficiently removing and disposing of a continuous web of matrix waste formed during the high speed manufacture of adhesive backed, pressure sensitive label stock on a printing press. As it leaves the press, the web of matrix waste is formed into a generally tubular rope in a cylindrical eductor. A controlled mixture of a high volume, high air and oil is used to pass the rope of matrix waste through an eductor, into and through a flexible hose, and into a compactor where the rope is compacted into relatively compact bundles. These bundles can then be readily deposited and efficiently stored in waste receptacles.
Abstract: A device and method for removing chips generated by a tool operating on a workpiece using air, and for lubricating the tool using a fluid lubricant are proposed. The device includes a manifold containing air and fluid lubricant chambers, at least one lubricating fluid nozzle connecting to the lubricating fluid chamber and at least two air nozzles connected to the air chamber. The nozzles are located so that the lubricating fluid stream is directed to impinge the tool from a given direction, and the air streams are directed so that neither the chips generated nor the air streams themselves significantly disrupt the lubricating liquid stream.

Abstract: An apparatus for automatically processing the wire ends of cores includes a forming die for bending the axially projecting wire ends back to project parallel to one another generally away from the core. Cores are received in a receiving station aligned with the forming die and orientated so that the wire ends are spaced as far as possible from the die. When the wire ends are sensed to be in the correct orientation, an actuator is operated to push the core through the forming die. The core with its wire ends bent back is then preferably stepped through a series of processing stations to trim and tin the wire ends and then ejected from the machine. A series of cores can be stepped continuously one after the other through the machine.
Abstract: A device wherein pharmaceutical capsules, each consisting of a separable bottom for receiving the said pharmaceutical product and a separable top for closing the said bottom, are fed in bulk into an input feedbox and sent, through a number of withdrawal and positioning ducts, to a rotary conveying device having two parts, one over the other, the first having a number of upper recesses for the tops and the second having a number of lower recesses for the respective bottoms, the rotary conveying device cooperating with a suction opening device designed to hold the tops inside the upper recesses and to suck the bottoms into the lower recesses, so as to separate the latter from the respective tops.
Abstract: A table (1) revolving intermittently and carrying on its periphery piece-holder grips, has central openings (11), which make possible the discharge of working shavings and wastes at the center of the table itself (arrow 12) and not at the periphery (arrows 7, 7') as now is done. This makes possible direct discharge of the working shavings and wastes in the collection container underneath and avoids clogging and stopping of the machine for cleaning which requires the presence of additional labor and limits production. Nozzles (13, 13') direct fluid radially inwardly to assist in this central discharge of shavings and wastes.
