Title: Composite mailer form
Inventor: VIGNEAULT ANDRE
IPC: B42C3/00
Filed: 1991-10-10
Granted: 2001-11-20
Abstract: A composite mailer and a method of forming same.      The mailer has a front and a back panel interconnected together along the top, bottom and side edges thereof by glue edge portions to form an envelope. The side edges are glue bonded along an edge strip thereof. One of the top and bottom edges has a fold glue flap formed integral with one of the front and back panels and folded over and glued along an edge of the other of the front and back panels to form a reinforcing flap to provide increased rigidity to the envelope for handling thereof by automatic mail sorting machines. One or more information-carrying sheets are interposed between the front and back panels and each has a connecting end edge portion glued between a common edge portion of the front and back panels opposite the edge having the glue flap. The information-carrying sheets have their other edges spaced inwardly of the glue edge portions.      A perforated line is provided below the connecting end edge portion to form a tear tab to detach the connecting end edge portions to provide access to the interior of the envelope while simultaneously detaching the information sheet from the connecting edge portion for their removal from inside the envelope. The information-carrying sheets are individual sheets and some of these sheets have folded sections.

Title: Adaptive filter capable of quickly identifying an unknown system
Inventor: SUGIYAMA AKIHIKO
IPC: H03H21/00
Filed: 1991-12-27
Granted: 1996-02-06
Abstract: In an adaptive filter formed by first through N-th delay elements connected in series to one another to define first through N-th taps, first through M-th coefficient circuits which are smaller in number than the delay elements and which produce first through M-th coefficient signals together with first through M-th calculated signals, an adder for summing up the first through the M-th calculated signals to produce an echo replica signal, and a subtractor for subtracting the echo replica signal from an echo signal to produce an error signal, a matrix switch circuit is arranged between the first through the N-th taps and the first through the M-th coefficient circuits and is controlled by a control circuit to adaptively select, from the first through the N-th taps, first through M-th taps connected as active taps to the first through the M-th coefficient circuits.  The control circuit supplies the matrix switch with a matrix control signal which includes active tap numbers assigned to the active taps.  A plurality of the active taps may be replaced by changing a replacement time interval determined by the control circuit with reference to a result of monitoring the error signal or the coefficient signals.  Alternatively, the control circuit can change an initial assignment to the first through the M-th taps from one to another when a dispersive portion of an impulse response has not been searched out for a long time.  On the other hand, the control circuit concentratedly sets the active taps once the dispersive portion has been found out by monitoring a maximum absolute value of the first through the M-th coefficient signals.

Title: Peristaltic voltage blocks
Inventor: JAMISON CHRIS M
IPC: B05B5/16
Filed: 1992-03-17
Granted: 1994-04-19
Abstract: Peristaltic Voltage Blocks Abstract of the Disclosure A coating material dispensing system comprises an electrostatic high potential supply having an output terminal on which the supply maintains a high electrostatic potential, a source of coating material, and a dispenser for dispensing the coating material.  The output terminal is coupled to the dispenser to supply potential to the coating material dispensed by the dispenser.  A peristaltic device couples the dispenser to the source of coating material.  The peristaltic device has a length of resilient conduit and contactors for movably contacting the length of resilient conduit at multiple contact points for substantially dividing the coating material in the peristaltic device into discrete slugs of coating material substantially to interrupt the electrical path through the coating material from the terminal to the coating material source.  The peristaltic device includes an inlet end for coupling to the source of coating material.  The length of resilient conduit has a first inside transverse sectional area at a first location along its length when it is filled with coating material at the first location and a second inside transverse sectional area larger than the first at a second location along its length further from the inlet end than the first location when it is filled with coating material at the second location.
Patent CA-2063333-C (CA)
Title: Data fault detection system
Inventor: SEKINE SHIGERU
IPC: H04L1/22
Filed: 1992-03-18
Granted: 1999-05-04
Abstract: A fault occurring in a data frame is detected, thus avoiding incorrect data processing when the data frame is transmitted between a high-level unit and a low-level unit through a down transmission line or an up transmission lines which are used for connecting the high-level unit and one or more low-level units in series.  The data frame includes at least two fault monitor bits with an alternating bit pattern having different binary values.  Each low-level unit detects fault monitor bits with an alternating bit pattern having uniform binary values "HH" or "LL" as an alternating bit pattern breakdown fault occurrence.  When fault monitor bits of a data frame have a broken alternating bit pattern, being detected by a fault detecting means in the low-level unit as an alternating bit pattern breakdown fault occurrence, the low-level unit transmits a fault-occurrence notifying signal to the high-level unit through the up transmission line.  It is desirable to use a signal also conveying a broken alternating bit pattern of "HH" or "LL" as a fault-occurrence notifying signal.

Inventor: HIRATA HIDEYUKI
IPC: G06F5/16
Filed: 1992-04-10
Granted: 1996-05-14
Abstract: In an elastic store supplied with a sequence of reception data, a sequence of reception clock pulses, a sequence of reception frame pulses, a sequence of system clock pulses, and a sequence of system frame pulses comprisi.ng successive system frames each of which has a system frame phase, a first signal generating circuit alternately controls write-in operation of first and second data memory blocks in response to the reception clock pulses and the reception frame pulses.  The first and the second data memory blocks thereby memorize the reception data as first and second memorized data, respectively.  A second signal generating circuit alternately controls read-out operation of the first and the second data memory blocks in response to the system clock pulses and the system frame pulses.  The first and the second data memory blocks thereby deliver the first and the second memorized data as first and second read-out data, respectively.  A selector selects one of the first and the second read-out data as selected data and delivers the selected data as output data synchronized with the system frame phase within a predetermined phase difference.

Patent CA-2077125-C (CA)
Inventor: BRYDON LOUIS B
IPC: B64G1/54
Filed: 1992-08-28
Granted: 2002-04-09
Abstract: A self-supporting convex cover for spacecraft hardware is described. In the preferred embodiment, the cover is made of a laminated material. Strips of material are inserted into the laminate in a channel shape, such that sufficiently rigid box beam structures are formed in a pattern to hold the convex shape. Ribs of foam may be placed between a layer of the laminate and the strips of material to provide the channel shape. The cover is attached to the spacecraft hardware by one or more drawstrings which are laced through the perimeter of the cover. With appropriate materials, the resulting assembly is light, inexpensive, easy to assemble, and transparent to radio frequencies, yet sturdy enough to maintain its shape during launch.

Title: Continuous on-line measurement of fluid or slurry viscosity
Inventor: COWPER NORMAN TERRY
IPC: G01N11/08
Filed: 1991-03-18
Granted: 2001-05-15
Abstract: A rheometer or viscometer for continuously measuring the rheological properties of non-Newtonian, mixed phase fluids or slurries.    The device has a vertically disposed, inverted U-tube to maintain solids in suspension and, therefore, exhibit a homogeneous character. The fluid flow rate is controlled to assure nonturbulent laminar flow through the tube.    Pressure is measured at a point in each leg of the U-tube and compared. For a constant flow rate, the pressure drop over the tube is used to measure the viscosity of the fluid in the tube.
