Title: Set screw
Inventor: CORRIGAN NIALL
IPC: F16B35/00
Filed: 1991-08-12
Granted: 1998-04-07
Abstract: This invention relates to a set screw comprising a shank having external threads and a work-engaging end portion integrally formed at one end of the shank.  The work-engaging end portion has a frustohemispherical outer surface comprising a plurality of circumferentially spaced serrations in the form of teeth.  Each of the teeth comprises a ramp extending outwardly from a root to a crest thereof with the ramp being inclined in a direction which is opposite to the direction of rotation of engaging the set screw in a workpiece.  A cavity is formed in the outer extremity of the work-engaging end portion.  The cavity cooperates with the frustohemispherical outer surface to form therebetween an annular wedge.

Filed: 1993-02-19
Granted: 2003-01-14
Abstract: A method and apparatus for inspecting articles such as printed circuit boards doubles the transport rate for the article under inspection, and modifies the manner in which acquired video images are processed to account for this change in rate.      Primarily, this involves two modifications to existing video processing systems including a change in synchronization for obtaining the frames which are to be processed, and a selective exposure (i.e., shuttering) of the video cameras to the images which are to be acquired in order to avoid the acquisition of plural images in a single frame. Once acquired, the video images are stored and processed making use of techniques which substantially correspond to those previously employed by existing inspection devices of this general type.

Title: Method of creating detachable solder connections
Inventor: BEAUMONT GUY D
IPC: H01L21/60
Filed: 1993-12-06
Granted: 1996-12-31
Abstract: A method is provided for creating solder connections between two surfaces which connections are relatively weak and thus can be readily fractured for separating the surfaces. The preferred application of the disclosed process is its use in connecting semiconductor chips to a carrier in order to conduct burn-in tests on the chips. The process consists of a series of steps to form a surface having a matrix of wettable and non-wettable areas on the pads of the carrier. Once the solder balls on the chip are attached to the treated pads on the carrier, electrical contacts are made and the chip can be readily removed after the test. The uniquely configured carrier can then be-reused numerous times for testing chips.

Title: Method for hydrophilizing absorbent foam materials
Inventor: STONE KEITH JOSEPH
IPC: C08J9/28
Filed: 1992-08-07
Granted: 1998-02-03
Abstract: Normally hydrophobic foams, such as polyurethane foams and polymerized water-in-oil emulsion foams, are rendered hydrophilic by means of treatment with sorbitan monolaurate.  Thus, a polymeric foam can be prepared or treated with sorbitan monolaurate and thereafter dried to leave a substantially uniformly distributed residue of sorbitan monolaurate on the internal foam surfaces. The resulting treated foams are rendered hydrophilic and are thus suitable for use in absorbent devices, including diapers, sanitary napkins, bandages, and the like.
