Abstract: A portable billiard ball polishing device configured for use with a buffing pad comprising a generally hollow body having a closed bottom surface, arcuate sidewalls and an open upper surface. The hollow body sidewalls are segmented to provide lower and upper cavities of varying diameter, to receive a first resilient pad in the lower cavity, and a second resilient pad in the upper cavity of the device, and a sleeve-shaped inner liner configured to the sidewalls of the hollow body.

Abstract: Tools and tool supports in a press which permit a tool changeover operation to be performed quickly and easily are disclosed. A pivot arm is carried on a ram of the press. A punch has an aperture formed therethrough, allowing it to be slidably mounted on the pivot arm. The punch is normally retained by a keeper for use in a first operating position on the pivot arm. The punch may be reversed for use in a second operating position by raising the keeper out of its retaining position and moving the punch along the pivot arm toward a second position. There, the punch can be rotated one hundred eighty degrees about the pivot arm. Then, the punch is moved back to the first position. The keeper automatically retains the reversed punch adjacent to the first support block when the punch is moved back to its original position. To remove the punch from the pivot arm, a retainer pin is removed, allowing one end of the pivot arm to pivot away from the ram.

Abstract: A cue tipper 42 for a stick 33 includes a positioner 44 having in a side 47, a cavity 48 centered around a preferred assembly axis V--V and facing toward a stick holder 54. Holder 54 has a device 56 to clamp a cue stick so a planar free end 35 faces cavity 48 and its centerline C-S coincides with the assembly axis V--V. A mover system 60 has a guide pin 62 affixed to holder 54 and extended slidably through positioner 44. A mover pin 64 is connected to positioner 42 and is threadably engaged to holder 54. In operation, a tip 20 has a planar end 26 contacted to the free end 35 of stick 33 and the positioner 44 and holder 54 are moved together by system 60. Cavity 48 engages primarily a desired dome 30 of a cap 22 on the tip 20and tip 20 is moved laterally and rotatively as required normal to assembly axis V--V until base plane 29 of dome 30 is made normal to axis V--V and dome centerline C-D coincides with axis V--V in a disposition preferred by pool players.

Abstract: A 3-D measurement system utilizing a holographic scanner is provided with beam direction compensation means for compensating for changes in angular deflection of the scanner and further means is provided for synchronizing the scanner diffraction segments with the camera imaging mechanism of the 3-D system as well as for providing multiple offsets of the projected beam.
