Abstract: Apparatus comprising an indium bump (11) that may be etched in a low concentration of hydrochloric acid (typically 1%) to remove oxide buildup, and a pad generally comprising a three layer arrangement of gold (16) over nickel (15) over titanium (14). The indium bump (11) and the gold pad (20) are pressed together for a short period of time, typically on the order of ten seconds, and then the pressed components are allowed to alloy weld over an extended period of time. 
Alternatively, the bump and pad may be heated at approximately 100 degrees Celsius for a period of about one hour to accelerate the alloy process. The heating diffuses the gold from the pad into the indium bump, thus forming a true alloy weld between the two that has incredibly strong bonding strength. Such bonding materials and men are useful in bonding integrated circuit components, and the like.

Title: Method of inserting active viscous ingredients in the housing of a galvanic element
Inventor: SAUER HANS
IPC: H01M50/618
Filed: 1990-11-06
Abstract: In a metering device (1), which operates on the principle of a hose pump, for active, viscous ingredients of galvanic elements, a compression roller (4) can be moved cyclically by means of operating cylinders (6, 7) relative to a straight rubber-elastic hose (2) in such a manner that, during the actual operating phase, a quantity of fluid material (8), for example a zinc gel, corresponding to the filled volume of this hose section is pressed out of the nozzle (9) by rolling off along a predetermined hose path a b in the direction of the outlet nozzle (9) with simultaneous pinching of the hose. Subsequent dripping of the ingredients (8) is suppressed in that a further movable roller (5) exerts a brief pinching at a point on the hose which is connected in a sealing manner to the section (a-b) after the roller 4 has completed the operating phase.

Inventor: HILLIARD JOHN C
IPC: F23C99/00
Filed: 1990-02-23
Abstract: In one aspect, the apparatus includes a pair of spaced electrodes (96, 112) through which a hydrocarbon fuel gas is flowed. An electric arc is struck across the electrode gap to pyrolyze a portion of the hydrocarbon fuel gas, leading to the formation of carbonaceous heat radiative bodies which are entrained in the hydrocarbon fuel gas stream. In the presence of an oxidant gas such as air, a turbulent diffusion flame (36) is created having an increased luminous radiant heat output, an improved turn-down ratio, increased flame stability, and reduced nitric oxide emissions. The method and apparatus are particularly adapted to increasing the luminous radiant output of hydrocarbon fuels having a low carbon-to-hydrogen ratio such as natural gas. In another aspect, a method and apparatus are provided by which the accumulation of pyrolytically formed carbonaceous bodies (312) on an electrode during the pyrolysis of a hydrocarbon gas is effectively prevented by a secondary gas jet. In still another aspect, the present invention provides a method and apparatus for controlling the rate at which heat-radiative carbonaceous particles in a diffusion flame are oxidized by introducing a protective sheath of non-oxidant gas as a tertiary flow circumferentially around a stream of fuel gas having entrained heat-radiative carbonaceous particles. Various modification of these methods and apparatus are also provided.

Abstract: A press, and a process of printing a combination of fixed and variable data on such press, is disclosed wherein printed images being manufactured are created by direct digital driving of an imaging device at normal press speed, optionally followed by one or more processing operations in the case of business forms or the like, as required for a particular job. The content or arrangement of printed images can be changed without stopping the press. The press and process use one or more unique electrostatic printing engines (PE1, PE2) having direct digital imaging on a photoreceptor surface 51 of a drum 50 which can create latent electrostatic images at normal press speeds, and can accommodate substantial speed variations. An electronic imaging system is provided in which base image data and variable image data can be combined electronically to drive a single exposure system 70 in a printing engine. Repetitive latent images are formed and developed using a high resolution liquid toner, and the resultant visible image is transferred and fixed to a wide variety of materials, preferably in a continuous web W. The photoreceptor surface 51 is cleaned and thoroughly dried each revolution so as not to interfere with the next charging of the drum. With this imaging system and printing engine, makeready time between successive printing jobs can be significantly reduced. The press also has a fuser/dryer 23 in which the developer carrier liquid is vaporized from the drum and treated through a catalytic converter to control emissions from the press. Heat from catalytic treatment of the volatile carrier liquid is utilized as a heat source for air used in fuser/dryer 23, thus providing a recuperative system.
