Title: Axial reactor with coaxial oil injection
IPC: C09C1/00
Filed: 1989-08-07
Abstract: An axial flow carbon black 
reactor (10) for producing carbon black 
particles having a relatively narrow 
particle size distribution. Feedstock oil is 
introduced into the reactor by a spray 
nozzle (12) located coaxial with the

Title: High speed data transfer on a computer system bus
IPC: G06F13/28
Filed: 1990-01-11
Abstract: A computer system bus is described which includes signal lines for 
controlling a high speed block data transfer mode between a bus master 
and a bus slave. When both master and slave devices support such a 
transfer, a high speed bus clock separate from the normal bus clock is 
used to transfer data. Devices not involved in the high speed block 
transfer see only an extended normal data transfer. The master and 
slave use bus control signals to determine the speed and data width of 
the high speed transfer. If the slave is unable to transfer the 
complete block of data at the high speed clock rate, it can signal the 
master to repeat the transfer of individual data items as necessary.

Patent EP-0570918-A3 (EP)
IPC: B23B31/12
Filed: 1993-05-18
Abstract: A chuck has a spring connection between the nut which rotates to advance or retract the jaws and the control ring or sleeve which the user rotates to operate the chuck. The spring normally transmits tightening or loosening rotation from the sleeve to the nut. When the jaws contact a tool, however, the spring allows the sleeve to continue to rotate even though the nut is stopped by the jaw-tool contact. Continued rotation of the sleeve relative to the nut causes a cam mechanism interposed between these two elements to force the non-rotating nut axially forward. This applies a final tool-gripping force to the jaws. <IMAGE>
