An apparatus, system, and method are disclosed for positioning a printed circuit board component. A clamping member applies a clamping force to a levering member linked to a positioning member. The levering member biases the positioning member toward a printed circuit board in response to the clamping force. The positioning member positions the printed circuit board and a component disposed on the printed circuit board in response to the positioning member bias. In one embodiment, the positionin...

An apparatus for use with a device for producing a suitable electric field to effect the electrodynamic spraying of solutions, dispersions, or mixtures of solids. The apparatus includes at least one spray station for spraying into a given spray zone. Each spray station includes two spaced apart tanks for holding the medium to be sprayed and which are disposed on both sides of the spray zone. An endless band is supported by pulleys disposed at each tank for circulating the band and constantly run...

Hydraulically operated working machine such as a puncher provided with a piston retracting mechanism including a high power piston retracting element or elements such as an urethane body or bodies or a washer spring or springs and disposed outside the machine main parts confining a piston chamber, all the auxiliary elements such as a piston shifting mechanism being incorporated within the machine main parts for convenience in use and transportation of the machine.

A closed cigarette filter for preventing tobacco from coming into direct contact with the mouth of the user and filtering undesirable products in the smoke, which includes strip of filter material having one edge cut to define multiple, adjacent panels or fingers, which strip is capable of being shaped in a tubular configuration and applied to the end of a cigarette, with the upward-standing panels located above the open end of the filter and the panels subsequently folded inwardly, either in at...

A preformed planar structure is interposed between the chip(s) and the substrate in a flip-chip structure, and establishes a minimum gap between the chip(s) and the substrate. Liquid flux may be applied to the preformed planar structure in order that flux is selectively applied to the solder balls (pads) on the chip and the substrate. The preformed planar structure may be provided with through holes in registration with the solder balls on the chip(s) and the substrate. In this case, liquid flux...

There is described an array of charging electrodes such as are used in ink jet printers. At least portions of the exposed surfaces of such electrodes, used to charge passing ink drops, are overcoated with a continuous coating substantially free of cracks of a semiconductive material doped to have a resistance, at room temperature, when measured transverse to the electrode, of between 10.sup.8 and 10.sup.11 ohms, such material being essentially insoluble in the ink.

A paint storage vessel is disclosed which is subdivided by flexible insulation into two interior spaces, each connected to its own distribution line and its own paint supply line. The ring main system is connected to the two distribution lines and is effected with the interposition of an electrically insulating change-over mechanism.

A surface mountable leadless fuse generally includes a tubular fuse sub-assembly with an insulating body molded thereto in intimate sealing relation. The tubular fuse sub-assembly includes a nonconductive tubular housing, cup-shaped metal end caps enclosing the housing. The insulating body includes an upper and lower portion which are integral as molded. The end caps protrude from a bottom surface of the insulating body so that the fuse can engage the flat conductive areas of a circuit board for...

In a method and a device for redundant transmission of protection commands between remote tripping devices (1, 8), useful information which represents a protection command or a rest signal is transmitted by a first remote tripping device (1) in at least two time slots via a first interface (2) to a first multiplexer (3), and is transmitted via different transmission paths (4, 5) by the multiplexer (3) based on the time slots. A second multiplexer (6) receives the useful information via the diffe...

A self-darkening shield for replaceably attaching to a torch. The self-darkening shield includes a shield and apparatus. The shield replaceably attaches to the torch, is self-darkening, and is a plate that is substantially inverted U-shaped to straddle the torch to provide shielding not only above the torch but also to its sides. The apparatus is operatively connected to the shield and replaceably attaches the shield to the torch.
