Title: Method for anchoring bolts for shaft-lining protection
Inventor: LEE SONG-WOO
IPC: E21D20/00
Filed: 1987-10-13
Granted: 1991-03-30
Abstract: The method anchors bolts in existing concrete structures  for their expansion. The anchor bolts each have disk plates mounted on it in even spacings for the anchoring portion to be plated in  the anchoring hole. The disk plates each  have  projections  on  their peripheral edges to keep annular spacing between the hole wall and the disk edge. The disk also has a hole for holding  an  injection pipe and a hole for an air outlet  pipe.  The  front  end  of  the injection pipe is arranged to protrude above the top disk plate to spout the injection material in  the  space  gap  defined  by  the disks. A hot wire is wound on  the  injection  pipe  and  the  air outlet pipe and is connected  to  the  disk  plates  to  heat  and expedite the curing of the expoy filler.

Abstract: Optical wave guides are interconnected with the use of two interfitting shell parts which when fitted together form a continuous tubular channel for receiving the wave guides between there. For this purpose a carrier shell part is provided with a continuous longitudinal groove of a size to accommodate a cover shell part and each part has a longitudinally extending receiving channel portion of complementary form which fit together and form a continuous receiving channel for the optical wave guides which are to be interconnected. After the wave guides are placed end to end in the longitudinally extending wave guide receiving channels defined in the carrier shell, a cover shell is engaged over the carrier shell in a manner which positions it complementary optical wave guide channel with the wave guide channel defined on the carrier shell portion. Wave guide channels are advantageously made with curved up portions at respective ends of the interfitting carrier shell and cover shell. Advantageously, the cover shell has terminal rib portions which engage over weak edges of the outer surface of the wave guide carrier shell.

Abstract: A process for making additive multilayer circuit boards wherein an insulating film (16 preferred a photo-processible film) is bonded to a pre-existing multilayer structure and selected areas of the insulating film are removed down to underlying metal sites (14) for electroless plating. All of the apertures in the insulating film are then electrolessly plated full of metal flush to the upper surface. Additional patterned composites are applied and plated up as desired to create blind vias and new conductor patterns layer by layer. In a preferred embodiment the insulating film (28) supports a patterned conductive metal foil (30) and is bonded foil pattern side down to the substrate. In an alternate process a foil clad composite is bonded to an existing substrate foil side up. The insulating layer is selectively etched through windows photoetched in the foil layer. The voids in the insulator layer expose copper sites on the underlying composite. The voids are plated full of metal to form vias and the foil layer is photoetched to make a conductor pattern. The process is repeated to make a multilayer PWB.
