A laminating apparatus for improving the uniformity of the thickness of a resulting laminate to improve the yield of products such as laminates is provided. A pressing device includes: a first press block movable back and forth; a second press block disposed in opposed relation to the first press block; a first pressing plate mounted to the inside of the first press block; and a second pressing plate mounted to the inside of the second press block. The first pressing plate and the second pressing plate are opposed to each other. A surface of the first pressing plate which is opposed to the second pressing plate has a peripheral portion formed into a tapered surface in such a manner that the distance from the second pressing plate increases in an outward direction.

An ultrasonic welding system. The system includes an ultrasonic transducer assembly having a horn and a first transducer and a second transducer arranged to impart ultrasonic energy into the horn. The horn has a first part-interfacing surface and a second part-interfacing surface opposite the first part-interfacing surface. An actuator assembly is operatively coupled to the ultrasonic transducer assembly and configured to cause rotation of the horn. A controller is configured to: cause the actuator assembly to rotate the horn so that the first part-interfacing surface applies the ultrasonic energy to a first part along an entire length of the first part-interface surface while a first ultrasonic energy is applied through the horn via the first transducer to cause the first part-interfacing surface to vibrate back and forth along its entire length as the first ultrasonic energy is applied by the first transducer to the horn.

In exemplary embodiments of the present invention, various novel dispensing devices can be provided. Such devices can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Novel sprayer/foamer heads can include buffers of various types. By using a buffer, a user need not continually be pumping the device in order for the device to be spraying or foaming. In exemplary embodiments of the present invention, such a buffer can be spring loaded, spring loaded combination, elastomeric or gas. In exemplary embodiments of the present invention, the buffer can be in line or adjacent to a piston chamber. If adjacent, it can be connected to the piston chamber with a one way valve, to provide for spray after a downstroke of the piston has been completed, or without, to allow spraying to cease once a user releases the trigger or other actuator. In exemplary embodiments of the present invention, such novel sprayers and foamers can be mounted upside down, in various “Flairomop” devices, used to clean floors or the like. When using a buffer, a piston chamber can be designed to deliver greater amount of liquid per unit time than can be possibly dispensed through the nozzle or nozzles. The fraction of liquid that cannot be sent through the nozzle(s), due to their inherent restriction, can thus be sent to the buffer for dispensing after the piston downstroke has been completed. A volume of the piston chamber, a volume of the buffer, a pressure response of the buffer, the throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.

A waterless toilet (1), at least comprising a tubular film (2), a transport unit for transporting the tubular film and a detection device (3) for detecting the tubular film (2), wherein the tubular film (2) has, over its entire length, a pattern (7) that can be detected by the detection device (3).

Aspects of the disclosure relate to envelopes for aerial vehicle. The aerial vehicle may include an envelope including a plurality of gores. The aerial vehicle may also include a seal arranged between a pair of the plurality of gores, the seal including six layers of envelope material heat-sealed together.

A heat sealing apparatus includes: a first sealing unit and a second sealing unit which are provided to be capable of being opened and closed and perform a heat sealing process of a bag while nipping the bag in a state where the first sealing unit and the second sealing unit are arranged in a closed position with the bag positioned between the first sealing unit and the second sealing unit; and a heat shield member including a heat reflector which is provided to cover at least a part of the first sealing unit and the second sealing unit arranged in the closed position, at a position away from the first sealing unit and the second sealing unit.

A container formed of a common one-piece thermoplastic substrate. The container has an overlapping seam having an overlap magnitude. At a location that is five times the overlap magnitude away from the overlapping seam, the container wall has a container wall Opacity less than about 50%. At a corresponding position along the overlapping sea, the overlapping seam has a seam Opacity that is less than 200% of the container wall Opacity.

A control circuitry (11) comprises an adjustable capacitor (C1), and a bias source (111) configured to apply a bias voltage (V2) to said adjustable capacitor (C1) to adjust a capacitance value of the adjustable capacitor (C1). Such a control circuitry may for example be part of a sealing device (1) to seal a medical tubing (2), the sealing device (1) comprising a receptacle (100) to receive said medical tubing (2), the receptacle (100) comprising an electrode arrangement for causing a heat action on the tubing (2).

A vibration measurement device measures vibration of at least one of the first sealing member and the second sealing member. A determination device determines quality of the sealing process according to a measurement result of the vibration measurement device from before the first sealing member and the second sealing member reach the closed position to after the first sealing member and the second sealing member reach the closed position. The sealing drive unit causes relative movement between the first sealing member and the second sealing member from an open position at a moving speed determined according to a type of the bag, to place the first sealing member and the second sealing member in the closed position.

The invention relates to a method for forming a laser-welded connection, in which two parts to be joined (11; 11a, 12; 12a) are connected to one another under the effect of a laser beam (1) in a joining region (30; 30a) to form a weld (2), wherein one part to be joined (11; 11a) consists of a material transparent to laser radiation and the other part to be joined (12; 12a) consists of a material absorbent to laser radiation, and wherein the two parts to be joined (11; 11a, 12; 12a) form a receptacle (25; 25a; 25b) for a component (13; 13a; 13b; 14) separate from the parts to be joined (11; 11a, 12; 12a).
