Title: Method & apparatus for printing postal code markings
Inventor: AGNEW EDWARD G K
IPC: G07B17/00
Filed: 1990-06-27
Abstract: The method of the present invention is intended to facilitate routing of correspondence to a destination address by automatic mail sorting apparatus comprising the steps: (a) marking a letter with an easily machine readable first code corresponding to the human readable postal code of the destination address; (b) stuffing the letter into a window envelope such that the first code is positioned within the window; (c) machine reading the first code within the window; and (a) printing a machine readable second code corresponding to the first code and the human readable postal code of the destination address in the location and format utilized by a particular automatic mail sorting apparatus such that the envelope is suitable for processing by the apparatus. The apparatus of the present invention includes a conveyor track for passing window envelopes through a read station and a print station. At the read station, an optical sensor reads the first code, in the form of printed marks signifying the postal code, through the window, the information being passed to a computer. At the print station, the second code, in the form of fluorescent or other marks are placed on the envelope, as instructed by the computer.
Patent CA-2020924-A1 (CA)
Inventor: YOSHINO KAZUNORI
IPC: F15B11/04
Filed: 1990-07-11
Abstract: A main poppet body of a logic valve receives inlet pressure  at  first and  second  ends.  A flow restricting orifice between the ends produces a differential pressure that maintains a pilot poppet body moveable in the main poppet body in sealing position, normally against a seat in the main poppet body, thereby preventing fluid at the second end from flowing. An external source of controllable pilot pressure acts on the pilot poppet body to permit a flow of inlet  fluid  from  the  second  end,  thereby  producing  a pressure reduction that tends to move the main poppet body out of its sealing position and consequently to permit an inlet flow past the seat of the main poppet body, to a drain. The position of the main poppet body varies in linear relationship to the pilot pressure applied to the pilot poppet body.

Title: Time division multiplex system and method having a time slot reuse capability
Inventor: PERDIKARIS ACHILLES
IPC: H04L12/52
Filed: 1990-07-30
Abstract: A multi-user Time Division Multiplex (TDM) system includes a plurality of stations and at least one erasure node located between groups of the stations. When a station reads the destination identification bits of a received time slot and determines that it is the destination for that slot, it sets the status of a slot-read bit, which follows the destination identification bits, to indicate that the slot has been read. When an erasure node detects a set slot-read bit it erases all or part of the associated slot, thereby enabling the reuse of that slot by subsequent stations. An interface apparatus, which enables the TDM system to connect the other TDM systems, filters intra-system communications from inter-system communications using the slot-read bit. When the interface apparatus detects a set slot-read bit it knows that the slot has been read and, therefore, is an intra-system communication which should be blocked or discarded. Since inter-system communications have notbeen read, the slot-read bit is not set and, consequently, the interface apparatus routes that slot to one of the other TDM systems as determined by the destination identification bits of the slot.

Abstract: A caster wherein an upright stub carries a swivel bearing for an inverted U-shaped frame having legs which support the shaft for a wheel. The shaft is movable sideways in elongated horizontal slots of the legs in response to depression or lifting of a pedal which is pivotably corrected to the legs. The pedal has two arms which flank the legs of the frame and are provided with substantially S-shaped slots crossing the slots of the adjacent legs and receiving portions of the shaft. When the pedal is depressed, the wheel frictionally engages and displaces a plate-like brake member which is vertically movably mounted in the legs of the frame and can be moved into direct frictional engagement with that part of the bearing which is non-rotatably connected to the stub. Alternatively, the plate-like brake member can be moved, into direct frictional engagement with bolts which secure the web of the frame to one race of the bearing whereby the brake member displaces a stub which is reciprocably mounted in the web and in the one race and moves into frictional engagement with another race which is rigid with the stub.

A running count of the transitions of the most significant bits of the interpolation signal  value  is  also  maintained  to  obtain  a  signal  value corresponding   to   the  total  of  intraline  complete   spaces traversed.   The  transition count and interpolation signals  are combined to provide a signal corresponding to the total intraline and interline distance traversed by the reading head.  (FIGURE 2)
