Abstract: A tool for segmenting a stack of bonded IC chips into short stacks includes a heat conducting base having at least one cavity in its upper face for receiving a portion of an IC chip stack. The length and width dimensions of the cavity are essentially the same as the corresponding dimensions of the stack. The depth of the cavity is selected to correspond to the desired thickness of the short stack to be formed from the stack. The base is heated to raise the temperature of the cavity walls to heat the stack above the softening point of the bonding material. A driver is movably mounted on the base for contact with a portion of a face of the stack extending above the opening of the cavity, and a threaded rod supported on the base urges the driver against the stack to effect separation of the extending portion of the stack from the segment portion which remains in the cavity. A track in the upper surface of the base is provided for travel of the driver.

Abstract: There is disclosed a wood shaving device which utilizes a rotating cutting member that supports a plurality of cutting blades which move past a stationary doctor bar. The cutting blades are arranged in a spaced-apart array on the shaving device, lying along non-radial paths so that the predominant action is a successive impact of individual cutting blades, rather than a simultaneous impact of two or more blades against the wood scrap. The cutting blades are preferably supported on a rotating cutting wheel which has a plurality of through apertures, with one each of the cutting blades removably mounted immediately adjacent each through aperture. The cutting blades are rotated past the doctor bar which restricts movement of the wood, resulting in a shaving action on the wood. The wood shavings pass through the through apertures of the cutting wheel and are removed.

Abstract: There is disclosed an aerospace fastener system in which a threaded bolt fastener is secured with a free spinning threaded nut or collar and in which the engagement of the threaded members is fixedly secured by an adhesive. In this invention, the length of the bolt fastener is preselected such that when the fastener is applied in a maximum grip condition, the end of the bolt fastener does not project beyond the top surface of the nut or collar. In this invention, the bolt fastener can even be slightly shorter than the length necessary to reach the top surface of the nut or collar when the fastener still meets the tensile load requirement of the specific application. Preferably the adhesive also includes an ultra-violet light fluorescent pigment so that upon ultra-violet illumination, the correct application of the fastener can be easily observed.
