A composition, device, and method for maintenance of railroad wood ties is presented herein. The device comprises a system for simultaneously filling rail spike holes in wood cross ties including a controlled system able to move in the x, y, and z planes. The system includes a product distribution box with multiple valves and dispensing lines for applying an environmentally friendly wood filler composition into multiple rail spike holes simultaneously. The wood filler composition is applicable for filling holes or gaps in wood to stabilize wood structures.

An apparatus for applying viscous material to workpieces has at least two material outlets. A needle valve is assigned to each material outlet, the valve needle of which being able to close the respective material outlet on a valve seat. Each valve needle is assigned a cylinder, in the piston chamber of which a piston is movable by pressure applied by a fluid, and which cylinder has a piston rod for impingement on the respective valve needle, the piston rod being connected to the piston, being guided out of the piston chamber on an end face facing the valve seats and extending longitudinally. The cylinders are arranged one behind the other longitudinally and the piston rod of at least one of the cylinders is guided in a sealed manner through the piston chamber of at least one further cylinder arranged closer on the valve seats.

A valve for free-flowing media, such as a glue valve, with a valve housing, and with a closure member, such as a valve tappet, which is movable in the valve housing by means of an electromagnet and which bears with a closure piece on a valve seat in the closed position of the valve and which sits at least partially in a continuous interior of a one-piece coil carrier on which the windings of a coil of the electromagnet are wound, and having two terminal receivers for a dosing unit and a valve lift adjustment unit with an elongate abutment part which is arranged at least in part in the interior of the coil carrier and which limits a movement of the closure member in the direction of the valve lift adjustment unit, with the valve lift adjustment unit being is secured on the coil carrier.

An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

Systems and methods for dispensing liquid materials as may be used in applications for coating flexible films and the like. Such a film may be coated by dispensing a rheological material onto its surface while drawing the film through a gap between a pair of rollers. The gap defines the thickness of a layer of the material applied to the film and is maintained at a desired width by microwires positioned through the gap. Another film across the gap from that to which the rheological material is applied aids in the coating of the layer and a contact area of the second film may be adjusted relative to the gap, e.g., when changing materials or when the coating film becomes abraded or deformed.

An applicator for dispensing adhesive onto a substrate is described. The applicator includes a manifold and at least one dispensing module coupled to the manifold. The applicator may include a least one pump assembly removably mounted to the manifold. Each pump assembly can have an outlet in flow communication with the manifold, and an inlet in flow communication with the adhesive. The use of a removable, independently controllable pump assembly can provide an operator of the applicator greater flexibility during adhesive dispensing.

The present invention refers to a flow measuring system and, more particularly, to a flow measuring system adapted for measuring a flow rate of sealant applied to a plurality of parts, the flow measuring system having a plurality of flowmeters, each of the flowmeters in fluid communication with a fluid injector, and the plurality of flowmeters being configured to generate, process and transmit a signal related to the flow rate of the injected fluid.

A discharge device includes a plunger unit (20) provided with three or more plungers (31), a plunger drive unit (60), a valve unit (40) including three or more metering bores (42) into which the plungers (31) are inserted, discharge ports (53) and a liquid material supply path (45) that are communicable with the metering bores (42), the valve unit (40) selectively taking a first position at which the metering bores (42) are communicated with the liquid material supply path (45) and a second position at which the metering bores (42) are communicated with the discharge ports (53), a valve drive unit (70) for switching over the valve unit (40) between the first and second positions, wherein the plunger holder (31) is detachably attached to the plunger drive unit (60) such that the number of the discharge ports and an interval therebetween can be changed depending on uses.

A preform coating device is provided with: a plurality of rotational holding parts that horizontally hold a preform; a conveyance part that conveys the preform by moving the plurality of rotational holding parts, the plurality of rotational holding parts being disposed at a predetermined interval along the conveyance route of the conveyance part; and a dispenser that discharges a coating liquid toward the preform. The dispenser has: a head including a mechanism for feeding the coating liquid; and a plurality of nozzles that are in fluid communication with the head and that each include a slot for discharging the coating liquid. The plurality of nozzles are disposed at a predetermined interval along the conveyance route. The interval between the plurality of nozzles is equal to the interval between the plurality of rotational holding parts.

A method for controlling a recirculation pump assembly is disclosed. The method includes receiving a process-dependent characteristic and determining a recirculation flow rate of adhesive that flows to the recirculation pump assembly based on the process-dependent characteristic. The method further includes determining a recirculation pump speed of the recirculation pump assembly for pumping the adhesive to a supply channel using the recirculation flow rate, and adjusting an operating speed of the recirculation pump assembly to match the recirculation pump speed. A system and storage device for performing the above method are also disclosed.
