Inventor: KOHN HAROLD
IPC: H05K3/12
Filed: 1986-08-26
Abstract: Apparatus 20 for applying solder paste 58 to printed circuit boards ("PCB's") 54 in a continuous operation. A drum 72 containing solder paste is positioned over a work station and has an outlet slot through which the solder paste can be discharged onto the surface of a PCB as it advances through the work station. A stencil 84 formed with a desired pattern for application of the solder paste to the PCB is rotatably mounted on the outer surface of the drum 72 and overlies the outlet slot. Gravity, machine vibration, and, if desired, air pressure are effective to discharge the solder paste onto the PCB with the aid of a resilient pad of a squeegee blade 96 adjacent the outlet slot. A drive mechanism 32 directly couples the translational movement of the PCB through the work station with the rotational movement of the stencil at the work station.

Abstract: method of manufacturing sintered nuclear fuel bodies by pressing of a powder of UO 2  containing 1-20 per cent by weight Gd 2 O 3  and possibly containing up to 20 per cent U 3 O8 into a pressed body and sintering of the pressed body. according to the invention the gadolinium in said powder consists at least partly of monoclinic Gd 2 O 3 . The monoclinic Gd 2 O 3  can be manufactured by heat treatment of cubic Gd 2 O 3  at a temperature of at least 1250°C. By employing monoclinic Gd 2 O 3  a considerably increased homogeneity with respect to solid solution of gadolinium in the UO 2  structure is obtained. Particularly favourable results are obtained if the sintering is carried out in a sintering atmosphere which, at 1750°C, has an oxygen partial pressure which is higher than 10- 7  atm.

Abstract: A display generation system comprises a memory 22 with a display portion storing display information, and an inactive portion storing test data. Scan logic 20 controls a monitor and accesses the memory at locations corresponding to the position of a scan beam of the monitor. A generator 16, 26, 28, 30, 32 generates display control information to provide information control signals to the scan beam, so displaying the information stored in the display portion of the memory. A register 34, 36 stores display control information generated from the test data stored in the inactive portion of the memory, the register being enabled by a control signal generated from the scan logic indicating the end of a display frame. The scan logic is operative during a period of time that the monitor is blanked to allow the scan beam of the monitor to be positioned to a beginning point of the display. An element 10 compares the display control information stored in the register corresponding to the test data with an expected result, the comparison being performed during the period of time the monitor is blanked, thereby verifying on-line that the display generation system is functioning correctly.

Abstract: A method, apparatus and feeder sleeves are described for producing casting moulds having feeder sleeves incorporated therein in instances when the mould pattern plate or the cope mould are not accessible. Two part feeder patterns having a lower part (la) and an upper part (l) and feeder sleeves (6) whose lateral surface tapers from the bottom and to the top end of the sleeve are used. For moulds having a side feeder the lower part of the pattern (la) produces a depressed seating sur­face (2) for the feeder sleeve (6) in the drag mould and the upper part (l) which has substantially the same taper as the taper of the feeder sleeve (6) and dimensions greater than the corresponding dimensions of the lateral surface (9) of the feeder sleeve (6) produces a cavity in the cope mould. The cope and drag moulds are closed in such a manner that the central vertical axis of the cavity in the cope mould is in line with the central vertical axis of the feeder sleeve (6), and there is a gap (7) between the wall (8) of the cavity and the outer lateral surface (9) of the sleeve. When metal is cast into the mould the sleeve (6) floats up and sits firmly and is sealed against the wall (8) of the cavity. For moulds having a top feeder the lower part of the pattern produces a depressed seating surface for a core whose upper surface has means for locating and centering the feeder sleeve.

Abstract: The present invention refers to a process for preparing 5-hydroxymethylfurfuraldehyde, which is also called HMF. This compound was yet prepared by dehydration of fructose-containing carbohydrates in the presence of various catalysts. Nevertheless, the separation of HMF from starting material, by-products and organic solvents was difficult and disadvantageous, especially by the presence of organic solvents. Surprisingly, it came out, that it is possible, to separate 5-hydroxymethylfurfuraldehyde from reaction mixtures, which are obtained by reactions of saccharides with an acid catalyst, in great purity and good yield with exclusive utilization of water as solvent, by means of ion exchangers, and to crystallize it out from chromatographic fractions.

Abstract: A polyurethane RIM method has two mixheads. Reactants are brought to each mixhead and are supplied as separate streams to two spaced cavities in a mold having a pre-formed porous mat separating the two cavities. One stream contains an isocyanate, polyol, chain extender and crosslinker selected to have a very low viscosity and which reacts to produce a high modulus armature or load bearing member. The other stream contains a polyol and isocyanate with additives that have relatively high viscosity to produce a semi-rigid polyurethane foam. At each mixhead the proportions of ingredients are controlled to give a desired isocyanate index to control the flex modulus and other properties of the loading bearing member and foam molded components of the product. The low viscosity material penetrates the porous mat to reinforce it and the porosity of the mat prevents the high viscosity material from entering the armature cavity so as to reduce the load capacity of the finished product.

Abstract: Large fittings or other structures are made by rotationally moulding a first component 18 of polyethylene and joining cylindrical pups 20, 22, 24 of polyethylene to the component by butt fusion joints 26, 28, 30. The structure within the boundary 50 is irradiated with gamma radiation followed by post-heating to remove free radicals. The extremities of the pups are shielded to prevent irradiation. Their capability to be joined to polyethylene pipes 12, 14, 16 by butt-fusion joints 32, 34, 36 is unimpaired. The irradiation introduces cross-linking to give improved properties such as impact resistance and stress crack resistance and to bring the fitting within the specification for polyethylene pipe for natural gas distribution. The joints 26, 28, 30 are made using differential heating of the ends to be joined to compensate for differences in melt flow index. Alternatively, the component 18 is slightly irradiated to lower its MFI before pups are joined to it.
