  • Patent number: 10993577
    Abstract: In order to apply decorative effects to a multilayered coffee surface, particulary a crema, a focused air jet for drawing or writing is contactlessly guided across the surface, wherein the air jet pressure at the action point is selected to overcome the surface tension of the multilayered surface and to produce swirls between the individual layers. To carry out this method, a wand is used as a writing implement, the wand containing a compressed air source and a switching element, and a small airflow tube (9, 15, 21) protruding from the housing (1, 10, 16) of the wand as a drawing- or writing nib. The compressed air source can also be a replaceable capsule (12) filled with a compressed air. It is particularly effective if a blower (19) driven by a battery-powered electric motor (18) is accommodated in the housing (16) of the wand as a compressed air source.

  • Patent number: 10551923
    Abstract: A toroidal actuator is responsive to a teleoperator for providing haptic feedback responsive to a curvature or articulated movement applied to a gripped object. The toroidal actuator surrounds an operator member such as a finger, and is responsive to pneumatic pressure for increasing telepresence force defined by resistance encounter against a teleoperated robotic claw. As the teleoperated claw grips an object, increased pneumatic pressure in the toroidal actuator tends to elongate the toroidal shape in a linear manner and oppose a curvature force applied by an inserted operator finger. Resistive force is based on soft sensing of the gripped object, thus the toroidal actuator applies an increasing resistive force to curvature as the robotic claw closes around a gripped object by solenoid regulated air pressure. A typical assembly includes at least 3 toroidal actuators for two digits and a thumb of an operator.

An exemplary rotary sprayer may include a spraying body configured to be mounted on a drive shaft of a drive motor for rotation with the drive shaft. The spraying body may further include a detachable mounting device for coaxial connection of the spraying body to the drive shaft. The detachable mounting device may include a spraying body thread that mates with a driveshaft thread defined by the drive shaft, and a plurality of elastic tabs configured to abut a corresponding cavity defined by the driveshaft, such that rotation of the spraying body increases an abutment force between the elastic tabs and the corresponding cavity of the driveshaft.

  • Patent number: 8789768
    Abstract: A variable arc sprinkler may be set to numerous positions along a continuum to adjust the arcuate span of the sprinkler. The sprinkler includes a nozzle body and a valve sleeve that helically engage each other to define an arcuate slot that may be adjusted at the top of the sprinkler to a desired arcuate span. The sprinkler may include a flow rate adjustment device that may be adjusted by actuation or rotation of an outer wall portion of the sprinkler. Rotation of the outer wall portion may cause a throttle control member to move axially to or away from an inlet, or may cause one or more restrictor elements to open or close, to control the flow rate of the sprinkler.

  • Publication number: 20140091156
    Abstract: A rotary atomizer spray coating device, in certain embodiments, has a bell cup with a generally parabolic flow surface. This generally parabolic flow surface provides additional surface area for dehydration of coating fluids, thereby improving color matching as compared to traditional bell cups, for example, by affording capability for higher wet solids content. In addition, the coating fluid accelerates along the generally parabolic flow surface, resulting in the fluid leaving the bell cup at a greater velocity than in traditional bell cups. Furthermore, a splash plate disposed adjacent the bell cup, in certain embodiments, is designed such that fluid accelerates through an annular area between the splash plate and the generally parabolic flow surface.

  • Patent number: 8668488
    Abstract: A process for the combustion of a liquid in a combustion chamber includes atomizing liquid sulfur using a rotary atomizer and introducing the liquid sulfur into the combustion chamber. The liquid sulfur is charged onto an inside of a cup. The cup is rotated so as to form a liquid film on the inside of the cup and so that parts of the liquid film are radially flung off from an edge of the cup edge into the combustion chamber. The rotational speed of the cup is varied so as to control a thickness of the liquid film in the cup to between 200 and 1000 ?m. The liquid sulfur is evaporated and subsequently burnt in the combustion chamber.

  • Patent number: 8444064
    Abstract: A rotary sprayer (10) for fluids (14), has a rotating disc (22), a drive (58) for the disc (22), and a supply device (28) for the application of fluid (14) onto the disc (22). The disc (22) has a distribution plane (30) for the fluid (14), and at least one opening (34) is provided in the distribution plane (30), via which a secondary flow (50) of the fluid (14) is separated from the main flow (48) to another plane (46). The disc (22) has a first spray edge (44) for spraying the working flow (52) of the fluid (14) and a second spray edge (54) for spraying the secondary flow (50) of the fluid (14). Since the main flow is divided into a secondary flow and a working flow, the effective amount of fluid that is used to moisten the workpiece can be reduced without having to therefore reduce the amount of fluid that is supplied e.g. via the pipe conduit. The formation of drops is thereby reliably prevented and a pipe conduit is used that has a cross-section of adequate size to prevent clogging.
