The present application provides an apparatus for preventing solder paste dripping, comprising: a working platform support apparatus; a working platform connected in a fixed manner to one end of the working platform support apparatus, the working platform being used to bear a solder paste tub comprising a housing, with a solder paste nozzle being accommodated in the housing, the solder paste nozzle being mounted on the working platform, so that the solder paste tub is borne in an inverted manner on the working platform by means of the solder paste nozzle, with the housing being capable of moving relative to the solder paste nozzle so as to extrude solder paste accommodated in the solder paste tub from the solder paste nozzle; and a holder, the holder being connected to the housing of the solder paste tub and located above the working platform, and the holder being slidably connected to the working platform support apparatus, so that the holder can move downward as the amount of solder paste in the solder paste tub decreases, to adjust the relative position of the solder paste nozzle and the housing.

An adaptive hot melt feed system includes a melt system, a feed system, a gas control device, a sensor, and a controller. The melt system includes a heated vessel. The feed system is configured to deliver a solid material to the vessel of the melt system for melting. The gas control device is configured to control a supply of gas provided to the feed system to drive the solid material from the feed system to the melt system. The sensor can be configured to detect an amount of material in the vessel of the melt system. The controller is in electronic communication with the gas control device and is programmed to signal the gas control device to vary the supply of gas to the feed system based on a fill metric determined by the controller.

A pumping apparatus includes a pump chamber, a piston, a motor, and a controller. The controller determines an imaginary terminal point by referring to a dispense command, theoretical information, and a current position of the piston. The controller corrects the imaginary terminal point to a target position by referring to a correction graph. The controller outputs a drive command to the motor for moving the piston from a start position to the target position.

A device for performing a surface coating of pieces is disclosed. The device comprises a housing, including one leak-tight cavity containing a drum, heating means, at least one water inlet conduit and one dyeing agent inlet conduit, and a recovery tank and a fluid recirculation circuit from said recovery tank to said leak-tight cavity and drum. The leak-tight cavity includes a first level sensor connected to a control device, such that the entry of water to the leak-tight cavity is interrupted when a specific level is reached inside the cavity, and the recovery tank includes at least a second level sensor connected to the control device, such that the entry of water and dyeing agent to the leak-tight cavity is interrupted if a specific level is exceeded inside the recovery tank.

The present invention is directed to a process, which can be used in the production of exhaust catalysts. In particular, the present process describes way of testing the leak-tightness of the coating equipment before a new coating campaign begins or during a running campaign.

A device for detecting and replenishing a salt solution in a salt spray machine and the salt spray machine includes a salt solution collector installed at the bottom of the salt spray machine and configured to collect the salt solution, a return pipe is connected to the salt solution collector and the salt solution storage tank, and a pH value sensor, a water level sensor and the salt concentration sensor are connected to the salt solution storage tank.

A coating device for supplying a liquid to a substrate, particularly in the form of an optionally printed web, foil, strip or sheet, comprises a reservoir for holding a quantity of liquid. A coating assembly is provided which is able and configured to take liquid from the reservoir and transfer it to the substrate. A supply delivers the liquid into the reservoir during operation. The supply is controllable and is able to lead a constant liquid flow into the reservoir. The reservoir is provided with a level detector capable and configured to detect a liquid level in the reservoir. Provided between the level detector tools and the coating assembly is a control which controls the coating assembly during operation on the basis of a detection (LS) of the liquid level in the reservoir in order to maintain the liquid level at a fixed value.

A fluid pressure-feed device includes a main tank and a sub tank. The sub tank is connected integrally with an upper portion of a main follower plate that applies pressurizing force to a urethane adhesive inside the main tank. A drum pump is provided in an upper portion of a sub follower plate provided in the sub tank. While the urethane adhesive is flowing into the sub tank from the main tank, the urethane adhesive is fed under pressure from the sub tank to a fluid passage by actuation of the drum pump. While the main tank is being replaced, the urethane adhesive inside the sub tank is fed under pressure to the fluid passage by the drum pump.

First to eighth laser measurement sections (30a) to (30h) of a laser measurement unit (30) measures a height of a surface of powder resins (15) in a coil insertion range CA for every angular degree in a circumferential direction of a stator core (2). A control unit (18) computes the number of points where the height of the surface is lower than a predetermined height among measurement results at multiple points measured by the first to eighth laser measurement sections (30a) to (30h), where the number of points is defined as an index value indicative of a dispersion of the measurement results. When it has been determined that the index value exceeds a first predetermined value, a notification is issued by outputting from a speaker (32) a sound indicative of the fact that the index value that has been computed exceeds the first predetermined value.

An apparatus for melting thermoplastic material is disclosed. The apparatus includes a heated manifold and at least one heating element disposed within the heated manifold. The heated manifold defines a plurality of cavities, a pump supply passage, and a discharge passage. The plurality of cavities are spaced apart from one another, and each receives particles of thermoplastic material from a hopper. The particles of thermoplastic material are melted within the plurality of cavities. The pump supply passage receives molten thermoplastic material from the plurality of cavities and supplies the molten thermoplastic material to a pump. The discharge passage receives pressurized molten thermoplastic material from the pump and is in fluid communication with a dispenser. The heating element transfers heat substantially throughout the heated manifold.
