Patent CA-2073035-A1 (CA)
Title: Single stage demodulator with reference signal phase dither
Inventor: WINSTON CHARLES R JR
IPC: G01C19/72
Filed: 1991-06-24
Abstract: A fiber optic rotation sensor includes a fiber optic coil with light beams counterpropagating therein where the beams are phase modulated with a squarewave carrier at the coil eigenfrequency. The beams recombine at the coil output with a resultant optical intensity which is a measure of the change in sensor rotation rate.  The recombined signal also contains an error component due to squarewave carrier imperfections which cause high frequency spikes in the modulated rate signal resulting in rotational rate bias errors. The rotational rate bias errors are reduced by demodulating the modulated rate signal with a demodulator reference signal uniformly phase dithered about the carrier signal.

Patent CA-2079623-A1 (CA)
Inventor: MCKENNA JAMES L
IPC: H04L29/06
Filed: 1992-10-01
Abstract: A data communication controller having a memory access control unit characterized by a symmetrical access port architecture. The memory access control unit allows both a host processor and the medium access control (MAC) unit of the data communication controller to transparently access a single-port data packet buffer memory while operating a full specified operating speed and without interference between simultaneous memory access requests. The memory access control unit arbitrates asynchronous memory access requests from both the host processor and the medium access control unit, while permitting each of these processors unlimited access to the single-port buffer memory as if it alone had the full memory available to itself at all times. The above capabilities are achieved using automatic address incrementation and data-byte prefetching operations, without requiring the use of a port processor or additional internal data buses.
Patent CA-2082852-A1 (CA)
Inventor: KEEFE BRIAN J
IPC: B41J2/16
Filed: 1992-11-13
Abstract: In a print cartridge according to the preferred embodiment of the invention, a polymer tape having orifices formed therein and containing conductive traces has a substrate containing heater elements affixed to a back surface of the tape. Each of the heater elements in the substrate is located substantially behind each of the orifices. The edges of the nozzle member overlap the edges of the substrate, and the back surface of the tape is sealed with respect to an ink reservoir so that a seal substantially circumscribes the substrate. This allows ink to flow around the side edges of the substrate and into vaporization chambers associated with each orifice.      The conductive traces on the tape are attached to electrodes along the shorter side edges of the substrate so as not to interfere with the edge-feed of ink along the longer edges of the substrate. A demultiplexer on the substrate requires relatively few electrodes to be formed on the substrate for supplying energization signals to the numerous heater elements formed on the substrate.

Filed: 1993-01-21
Abstract: A method and apparatus is provided for controlling the speed of a slave drive roller in a coating machine. Speed of the slave drive roller at a second coater is regulated by an adaptive gain allowing greater tolerances when not at run speed.  That is, in addition to normal speed correction, the system accommodates greater web speed fluctuation during threadup,  acceleration,  and deceleration.   This accommodation may be based on the sensed position of the float roller or, alternatively, on the sensed rate of acceleration/deceleration of the master drive roller.

Title: Automatic molding system
Inventor: LAU CHUN P
IPC: B29C33/48
Filed: 1993-06-15
Abstract: ABSTRACT OF THE DISCLOSURE      A mold set is formed by sandwiching a preform between upper and lower plates.  Each plate has openings corresponding to areas on the preform to be encapsulated.  Upper and lower cover plates overlie the openings to form molding cavities.  A plurality of mold sets are conveniently stacked to form mold units which may be placed in a storage apparatus.     A first unit is transported to a station for preheating. After a predetermined time, the unit is moved to a molding station where it is clamped under pressure and plastic is injected into the mold cavities.  While molding is occurring, a second mold unit is moved from the storage apparatus to the preheating station.     After the first unit has undergone the molding and an initial cure step,  it  is unclamped and moved to  a curing station. Subsequently, the second unit moves into the molding station.  At this time,  a third unit may be transported to the preheating station.     After curing, the first unit is opened to remove the product and the separated plates are passed through a cleaning station for subsequent reassembly at an assembly station.   The first unit plates are reassembled and moved to the preheating station for preheating  while  the  third  unit  is  undergoing  the  molding operation.  During the third unit molding, the second unit is being cured and opened for product recovery.  The cycle is repeated with each mold unit and is coordinated with a central control system.   Efficiencies are obtained by aligning the mold parts into vertical  stacks  which  are  readily  conveyed  by  magazines  and carriage frames.  The operating stations are separated into upper and lower levels whereby gravity and simple elevator mechanisms may be used in an effective manner.

Title: Settable printing apparatus
Inventor: MITCHELL PAUL
IPC: G07B17/00
Filed: 1993-11-12
Abstract: A Settable Printing Apparatus ABSTRACT       In the field of, e.g., mail processing apparatus, it is known to provide encoding marks on settable members such as thumbwheels for setting the date to be printed on envelopes.  The encoding marks in known apparatuses are detectable by retro reflective sensors to determine the setting of the settable members.      Previous  such  apparatuses  are  disadvantageous  because  it  is necessary to provide a sensor circuit and a set of encoding marks for each thumbwheel,  etc.   Thus,  the arrangement is complicated and the processing of the resulting signals time consuming.      The disclosure relates to a settable apparatus for use in a mail processing apparatus, in which at least one settable member (10) includes encoding marks such as digits marked thereon.  A charge coupled device (17) is arranged to detect the encoding mark of one or more settable members simultaneously.  A lens (18) is disposed between the settable member and the charge coupled device to focus the image of the encoding marks onto the surface of the charge coupled device.      Thus,  the  settings of a number of settable members such as thumbwheels may be determined simultaneously.      An optional feature of the invention is a shutter which by be closed across the charge coupled device to protect it from damage, dust contamination etc. (Figure 1)
