Abstract: IMPROVED ROBOT-LASER SYSTEM               ABSTRACT        A robot-laser system having a minimum number of mirrors  for reflecting a  laser beam from  a  fixed  laser  beam  source  to  a  desired location wherein the mirrors are mounted within the hollow,  servo-controlled parts of the robot to  move  therewith.   Only  a  single  mirror  is mounted within its associated controlled part to reflect  the  laser  beam as  it  travels  between adjacent  controlled  parts.   The  robot  has  a number of degrees of freedom constituted by two orthogonally  related  linear  movements  along intersecting    longitudinal    axes    and    two orthogonally related rotary joints having inter-secting pivotal  axes.   Preferably,  two  of  the mirrors  are  mounted  so  that  the  laser  beam strikes and is reflected from both points of axes intersection within two of the controlled parts. In  one  of  the  disclosed  embodiments  a  mirror mounted in the base of the robot reflects the laser beam from the source to the other mirrors.

Abstract: Abstract of the Disclosure An air lock or transition chamber for controlling air pressure during ingress and egress from a multi-story building the interior of which is at an elevated air pressure.  An elevator car is provided with a substantially air-tight seal on its door.  Persons entering the building pass through an entrance lobby or an underground garage and enter the elevator.  These locations are an ambient atmospheric pressure.  The elevator doors close and the elevator moves to the desired floor, which is at an elevated pressure.  As the elevator car moves, the pressure within the elevator increases, either substantially to the elevated pressure of the destination or to a pressure between ambient atmospheric pressure and that elevated pressure.          Similarly, as the elevator car returns to the floor at ambient atmospheric pressure, the pressure within the elevator car decreases, either substantially to ambient atmospheric pressure or to a pressure between the elevated pressure and ambient atmospheric pressure.

Granted: 1990-08-21
Abstract: ABSTRACT            The high speed line adapter comprises a bit handling layer (34,46) and a byte handling layer (36,50) and a receive queue mechanism (48).     The bit layer receives the frames from the high speed line 9.          It performs the SDLC protocol,  it removes the flag and BCC characters and adds one ending condition control character which indicates whether the frame was correctly received or not. It causes the address and control fields, the data if any and the ending condition character to be stored into a receive queue buffer at the first free address.  The byte layer 50 takes out the frame characters from the receive queue as soon as a pool buffer is available in the memory of the central unit of the communication controller. It sends the data if any to said memory through a direct access memory bus and sends the address and control fields and the ending condition to the microprocessor of the adapter.     The provision of the receive queue mechanism allows high speed lines to be connected to a communication controller, without modifying its network control program.
