Title: System for discharge of bulk materials from vehicles
Inventor: KWOK ALEXANDER KING WAI
IPC: B61D7/26
Filed: 1992-06-05
Abstract: A system for operating hopper doors 14, 16 in a bulk transport vehicle comprises a pair of linkages 34, 36, 38, 40 forming an over-center locking arrangement and separate opening and closing trip levers 24, 50 attached to an operating shaft 30. The trip levers 24, 50 are operated by engaging associated cams 24, 54 as the vehicle is moved relative thereto. A single door or pair of doors may be operated at the same time. To prevent false triggering of the door mechanism in transit, a secondary lock can be provided where a spring or counterweight is used to bias a lever which restrains a governor. The governor moves between stops which determine the angular positions corresponding to the door(s) 14, 16 being opened or closed. The cams 24, 54 can be inactivated so as not to trigger the operation of the doors 14, 16 by being rotated, translated or lowered out of the path of the trip levers.

Patent CA-2077527-A1 (CA)
Inventor: KEUSCH SIEGFRIED
IPC: B27C3/04
Filed: 1992-09-03
Abstract: Abstract of the Disclosure The invention relates to a boring machine, particularly for woodworking, for boring rows of holes and structural bores in plate-shaped workpieces such as cabinet sidewalls, cabinet doors, etc., with a machine frame having a workpiece holder and an adjustable multi-spindle boring assembly arranged over the workpiece holder, a fixed, longitudinally oriented workpiece stop being mounted on the back of the workpiece holder, and which has a stop fixture consisting of stop rails aligned parallel to and projecting laterally at the longitudinal sides of the workpiece holder and whereat adjustable and lockable stop receivers can be introduced into the stop rails, the stop receivers receiving spring-loaded stop platelets, which project at the surface of the workpiece holding fixture, but which can be brought into a pushed back position.  The operation of the boring machine is simplified and facilitated in that the multi-spindle boring assembly is adjustable and lockable vertically to the longitudinal sides of the workpiece holder, that "n" stop strips with holding fixtures for stop receivers are combined into a stop roller with n angles in the cross-section, that the stop roller can be brought into n angular positions below the workpiece holder, whereby the stop platelets of the stop rail facing an opening in the workpiece holder project through this opening.

Title: Optical signal channel selector
Inventor: WEIR CHARLES S
IPC: A61B5/00
Filed: 1992-09-16
Abstract: Docket No. 32078 OPTICAL SIGNAL CHANNEL SELECTOR              ABSTRACT OF THE DISCLOSURE     The optical signal channel selector apparatus includes one or more first optical channels, and a plurality of a secondary optical channels for carrying an optical signal.          A  parabolic  mirror  is  rotatable  to  provide  optical communication between a first optical channel and any one of the secondary optical channels.   A position encoded stepper motor  is  coupled  to  the  parabolic mirror  for controlling  the position  of  the mirror.    Solid  state optical interface blocks having one or more filters receive the optical signal and transmit output optical signals with filtered  wavelength  ranges  in  the  secondary  optical channels.  The rotation of the mirror by a position encoded stepper motor allows  selection of  a  desired  secondary channel, and automatically shutters the remaining channels closed.

Title: Method for accessing an identified window into a multi-window interface
Inventor: SCANNELL PETER
IPC: G06F3/048
Filed: 1992-09-23
Abstract: ABSTRACT            The  method  of  the  present  invention  allows  direct  user management  of  the  display  of  a  plurality  of  objects, particularly opened windows,  on the display  surface of a computer monitor.  At least one window is identified by the user  for  priority  display  at  user  selected   times.  The computer  system  generates  a  priority  ordering  for  the opened  windows,  including  from  time-to-time,  the window identified   for   priority   display,    independent   of identification of a window for priority display. Responsive to the current ordering the computer assigns a display space on the  display surface to at least the first window in the ordering. Windows lower in the ordering receive assignment of display space to the extent display space is available. Responsive  to  user  initiated  action,  the  computer  will temporarily assign display space to  the window identified for  priority  display  notwithstanding  a  possibly  lower priority  ordering  to  other  overlapping  windows.   Such overlapping  windows  as  have  previously  been  assigned display   space   are   altered   in   appearance   to   avoid obscuration of the identified window.  Direct manipulation of the altered windows is blocked subject to release of the user initiated action.

Title: Pneumatic outlet
Inventor: DUGGE RICHARD H
IPC: B61D7/02
Filed: 1993-06-07
Abstract: Abstract of the Disclosure A Pneumatic outlet (10) is for use on a railcar (C) for discharging a lading from a hopper (H) of the railcar.  An improvement to the outlet comprises a bottom cover (16) extending the length of the outlet.  This cover is severable into two sections (44A, 44B) one of which is reversible with respect to the other.  The two sections are joined together to form an integral cover through which lading flows during discharge.  A bulkhead divider (48) is installed in the cover at the juncture between the two cover sections.  A pair of outlet valves (12A, 12B) are installed in the cover.  The valves are mounted on respective valve shafts (54A, 54B) which are installed in the cover with the inner end of each valve shaft being removably mounted on the divider.  An end closure (64A, 64B) is installed at each end of the outlet, and the outer end of each valve shaft is located adjacent a respective closure.  Each end closure is pivotally mounted to an end wall (90A, 90B) of the outlet.  This allows a closure to be rotated away from the end wall of the outlet and permits access to the interior of the outlet for cleaning the outlet, or for removal of a valve for repair or replacement.
