An apparatus for applying a strip of elastomeric material to a surface, the apparatus comprising: a nozzle having an inlet in fluid communication with a pumping means, said nozzle having an upper surface and a lower surface, wherein the lower surface has a curved shape for mating engagement with an outer surface of a rotatable roller, said lower surface having an opening positioned for engagement with the roller outer surface.

A retainer is rotationally driven about a axis of a ball bearing, and convex areas having pockets provided therein along a ball pitch circle of the retainer and concave areas between adjacent pockets is detected by a sensor. Grease is discharged according to phases of the convex areas and concave areas in the rotationally driven retainer from a dispenser having grease discharge ports arranged to face an annular space.

The invention relates to applying a liquid to pasty hot-melt adhesive to a substrate (44), comprising a template (29), having at least one cavity (38) for the hot-melt adhesive, and also comprising an adhesive-transfer infeed (33), which is assigned to the template (29) and through which the adhesive can be introduced into the cavity (38). The special feature consists in that the apparatus (10) further comprises a transporting-fluid-supply opening (35), assigned to the template (29), and a device for displacing (13, 15), in particular pivoting, the template (29) between a first position, in which the cavity (38) is assigned to the adhesive-transfer infeed (33), and a second position, in which the cavity (38) is assigned to the transporting-fluid-supply opening (35), and therefore the adhesive, in the second position, can be discharged from the cavity (38) by a transporting fluid flowing through the transporting-fluid-supply opening (35).

In manufacturing a laminated iron core by laminating and bonding iron core laminates blanked from a sheet steel strip into a prescribed profile, the adhesive agent can be applied to the iron core laminates in a stable manner without regard to the arrangement and the number of the application spots on each iron core laminate. The metallic die machine (1) is provided with an adhesive agent application unit (12) configured to apply an adhesive agent to a prescribed area of the sheet steel strip (W) corresponding to the iron core laminates (2), and the adhesive agent application unit is provided with a casing (44) defining a plurality of adhesive agent storage chambers (55-57) for storing the adhesive agent before the adhesive agent is applied to the prescribed area. The casing is provided with a plurality of ejection orifices (H1 to H3) each communicating with a corresponding one of the adhesive agent storage chambers and configured to eject the adhesive agent.

A droplet forming device (1) for discharging a droplet in a flying fashion from a nozzle (32), the device includes a liquid chamber (29) that is communicated with the nozzle (32) and is supplied with a liquid material (37), a plunger rod (6) having a tip (34) that is moved to advance and retreat within the liquid chamber (29), a spring (8) that applies a biasing force to the plunger rod (6), a pressurization chamber (11) that is supplied with a pressurized gas (10) acting to retreat the plunger rod (6), a pressure source (15) that supplies the pressurized gas (10) to the pressurization chamber (11), and a controller (45). The droplet forming device (1) further includes a magnetic field generating mechanism (21, 22) that generates an attraction force to act in an advancing direction when the plunger rod (6) approaches a most advanced position thereof.

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.

A liquid coating apparatus includes a liquid chamber, a diaphragm deformable to change a volume of the liquid chamber, a piezoelectric element that deforms the diaphragm in a thickness direction, a pressurized casing bottom-wall portion between the piezoelectric element and the diaphragm to support the piezoelectric element from a diaphragm side, a fixed casing bottom wall portion that supports an end of the piezoelectric element on a side opposite to the diaphragm, a plunger that extends through the pressurized casing bottom-wall portion and transmits expansion and contraction of the piezoelectric element to the diaphragm, and a coil spring that is between the piezoelectric element and the pressurized casing bottom-wall portion and is supported by the first support portion to apply a compressive force to the piezoelectric element.

A sealant discharging nozzle includes a nozzle body, a flat surface, a cutout, and a shaping portion. The flat surface is provided on the nozzle body and is formed on a discharge port side of a through hole that extends along a central axis of the nozzle body. The cutout is formed on a first side with respect to the flat surface. The shaping portion is, with respect to the flat surface, formed on a second side opposite to the first side.

A syringe attachment/detachment mechanism enables a syringe to be easily attached to and detached from a discharge device without causing twisting of a tube, and enabling the syringe and an adapter to be fixedly held in a desired orientation. In the syringe attachment/detachment mechanism and the device provided with the mechanism, the mechanism being adapted for a discharge device to which a syringe including an attachment part and an upper connection part is attached through screwing, the attachment part includes an inner cylindrical portion having a small-diameter opening, an outer cylindrical portion surrounding the inner cylindrical portion, and a screw portion. The attachment/detachment mechanism includes a support member including a cylindrical insertion portion into which the inner cylindrical portion is inserted, and having a channel formed therein for communication between the small-diameter opening and a nozzle of the discharge device. A rotation member includes a screw portion.
