Abstract: Solder particles 220 are deposited onto metallized contacts of a direct chip attach (DCA) site located on a substrate 301. The contacts 302 are coated with a layer of flux 303. A pick up head 211 is positioned in a reservoir 201 of solder particles 220 and particles are attracted to the apertures in the end 213 of the head. The apertures have an arrangement corresponding to the footprint of the metallized contacts on the substrate. The head 211 is positioned adjacent the substrate 301 and the particles 220 released. The particles 220 stick to the flux 303 coated on the contacts 302. The particles are reflowed, leveled and again coated with flux. An integrated circuit chip is then placed on the leveled reliefs 501 and the reliefs reflowed again to attach the chip onto the contacts 302.

Abstract: Where an electrical connection is needed between an electric circuit on a substrate and a component with very finely spaced leads, pads are formed on the substrate at points where such connections to the circuit are to be made. A solder paste is deposited using a particular, described stencil having a thickness and apertures with specific tolerances. The component is positioned so that its leads to be attached are contiguous with corresponding pads, and the electrical connections are completed by reflowing the solder paste forming consistent and reliable electrical joints of solder alloy.

Abstract: The method for soldering a chip to a substrate to form a module and then soldering the module to a circuit board includes selecting a three level hierarchy of solders by the temperature required to melt. By this method, a module can be soldered to and de-soldered from a circuit board without affecting adversely the solder between the chip and the substrate. The package formed by this method is free of faults that are caused frequently during both manufacture and service.

Abstract: An image generator system for producing real time imagery from a digital database includes processors performing in sequence: scene data management, geometry processing, and video processing. The scene data management processor selects and organizes the data base objects, modeled with polygons, and distributes polygons to parallel geometry processing modules. Geometry processing modules convert the images from 3-D to 2-D coordinates and divide the polygons into two-pixel-high scanline-aligned "spans". Spans are collected and sorted in a region buffer associated with each channel of a scene. Occlusion is done hierarchically to conserve time and bandwidth, and antialiasing is performed recursively for the same reasons.

Abstract: A metal carrier has a dielectric material with a thickness of less than 0.004 inch and electrical voltage insulation characteristics of at least 2500 volts formed on a surface. A donut configured land defines at least one via or opening for removing dielectric material selectively. Reflow solder is used to form electrical interconnections, and the vias provide thermal dissipation sufficient to conform to safety requirements.

Abstract: A method and apparatus for testing a new pipe coupling for a leak that could be too small to be detected visually involves a section of pipe, a hole through the pipe, a 90 degree ell affixed to the hole from inside the section of pipe, a length of tubing from the 90 degree ell extending to a tee outside the section of pipe, an air gage attached to the tee, and a tire pump attached to the tee for applying about 100 psi of air pressure to the interior of such pipe coupling through the hole to a small space between the section of pipe and the coupling, for locating a leak in the coupling after first sealing the pipe coupling to the pipe section, as done by observation at the air gage of a decrease in air pressure at such small space.

Abstract: A paper stacker includes adjustable sides to receive paper passively of different widths. The uppermost ends of the sides are flared to avoid paper encountering these ends, permitting the received paper to slide down between the sides to settle on a bottom surface without assistance. Each of the sides has a portion cut away to permit grasping a paper stack for removal. A trapezoidal platform is located on the bottom between the sides and has a friction material on a substantially flat upper surface to prevent paper slippage.

Abstract: A capacitor structure is described as having a plurality of dielectric materials located so that each dielectric material is in parallel between capacitor plates. The capacitor value of this structure is preset, therefore, for operation electrically at different specific temperatures. The description gives a specific stacked arrangement for the various dielectric materials in which this capacitor can be formed, as one example of that to which it is adaptable.

Abstract: An image generator with a system to affix a flag for identifying high resolution pixel data in a signal of both high and low resolution pixel data, so that high resolution pixel data is divided readily for separate treatment in a high resolution frame buffer. The low resolution pixel data is connected to a low resolution frame buffer where it is treated with an occlusion mask in accordance with occlusion fractional coverage computed separately. The pixel data is combined again in a mixer before it is converted for visual display.

Abstract: A base structure for receiving an electrical relay is described as being adapted to receive the relay removeably. Electrical contacts in the base connect the base electrically with the circuitry of the attached relay. Terminals are provided for the connection of external wiring to the base and are each connected to at least one of the electrical contacts. Permanent magnets affixed to the base attach the base securely to an electrical panel so that the base is easily removed. According to a modification, electro-magnetism is used to secure the base to the panel. A magnetic shield is disposed, according to a modification, between the source of magnetism and the attached relay.

Abstract: The mason's hand trowel has a blade member with a handle supported from the back surface of the blade by attachment members so that the handle is spaced a desired distance from the back of the blade. At least one, but preferably two surfaces are supported by a plate so that they are movable contiguously relative to a working edge of the blade member and an adjacent edge. At least one guide pin extends through an opening in the handle and is attached to the plate with its movable surfaces, and a spring extends from the under side of the handle to the plate to maintain the surfaces in a normally retracted position.

Abstract: Multiple circuit functions embodied in electrical circuit lines and areas are supported by a multilayered printed circuit board of various lengths and widths (defining "x" and "y" directions) and of various thicknesses (defining a "z" direction) all on a single board. Several ways of achieving such variations in thickness include providing two layer subassemblies arranged in an alternate and intermediate manner, one subassembly being adapted to support electrical circuit lines and areas, and the other subassembly being formed of thin film dielectric material of various precalculated thicknesses. Another way of achieving a variation in thickness is to limit the surface covered by circuit lines with a pre-calculated core thickness.

Abstract: A motion detection system detects both a soft, or near, jam and a complete, or hard, jam in movement of a paper web. A first sensor generates signals in response to the web driver, and a second sensor generates signals that are responsive to actual web movement. The signals from the second sensor are connected to a register to exhibit a signal state, and the signals from the first sensor are totalled in a counter between a cycle of changes in the state of the signal in the register. If there is a significant deviation in this total, an "error" signal is generated to advance a counter. If the number of "error"s are counted above a preset number, a shut down signal is generated.

Abstract: An energy dampening drawbar for use with receiver hitches and specialty types of hitches is described as including an elongated hollow shank having slots on opposite sides. A first cushion block is located within the shank and has a portion of the first cushion block adjacent one surface of a pin block. The pin block has a hole that aligns with a portion of the two slots. A second cushion block is located within the shank adjacent another surface of the pin block. A first restraint prevents longitudinal travel within the shank by the first cushion block. A second restraint prevents longitudinal travel within the shank by the second cushion block. A plate is attached to one end of the shank to provide a surface for attaching a trailer coupling.

Abstract: A system is described to separately furnish to an injector apparatus that is placed within a pipe two or more grout components. The injector apparatus is secured in position in the pipe by components of the injector apparatus that are urged into a position of cooperation with a modified section of pipe as a consequence of the increased hydraulic pressure that occurs within the injector apparatus during the pumping of one of the grout components thereinto. The two or more grout components after separately being furnished to the injector apparatus are then combined together by elements of the system and are then thoroughly mixed (reacted) together by other elements of the system to form a grout that is discharged from the system following their mixing together and prior to setting of the grout in ideal proximity with respect to a crack or crevice requiring grout application. All components of the system are recovered for subsequent use elsewhere.

Abstract: A round bale handling apparatus is described for the lifting, transportation, and unloading of round bales in cooperation with a motor vehicle. The apparatus has an upper frame assembly attached pivotally to a lower frame assembly. A conveyor on the upper frame assembly adjusts the position of bales on the apparatus. Lift arm assemblies have two sections spaced apart to place bales on the trailer one at a time and stacked. A stack of three bales is moved rearward on the upper frame assembly by the conveyor to provide additional space for loading additional bales. Side rails are attached to the upper frame and are adjustable by eccentrics to adapt the trailer to the size of round bale being loaded and to move the side rails pivotally toward the center of the trailer to conform to public highway regulations governing trailer width.
