Abstract: ABSTRACT           The present invention relates to a process for pacifying stickies in the papermaking process.  Accordingly, the present invention provides a paper making process in which paper furnish including recycled fibre is passed over drying rolls, wherein for the purpose of pacifying stickies in the paper product, an aqueous solution of urea is applied to the paper between the drying rolls and the finished produce reel.  The amount of urea applied is such that the paper product bears a coating surface of urea in an amount between 0.1 g/m2 and 2.0 g/m2 of paper surface.

Title: System for printed circuit board testing
Inventor: JACKSON DANIEL K
IPC: G01R31/28
Filed: 1988-09-08
Granted: 1992-01-14
Abstract: SYSTEM FOR PRINTED CIRCUIT BOARD TESTING ABSTRACT OF THE DISCLOSURE          A system is described for connecting a printed circuit board (PCB) under test to a digital anslysis unit to permit verification of the functional behavior of the PCB. A bed-of-nails (BON) fixture is employed, allowing access to internal circuit nodes of the PCB. Controlled-impedance wiring, terminated in its characteristic impedance at the test electronics, allows high speed signals to be communicated without degradation from the unit under test (UUT). Excessive dynamic loading of the UUT circuit nodes is avoided by employing isolation resistances at each BON probe. The potentially large number of UUT signals to be monitored is multiplexed down to a smaller number of lines more readily accommodated by the digital analysis unit. The selected signals from the UUT are processed in a wide-band asynchronous manner by the test electronics in such a way that uniform delay of all signals through the multiplexer is achieved. The digital analysis unit is able to monitor the operation of the UUT just as well as if neither the BON nor any intervening electronics were present. The high-speed functional behavior of the PCB itself remains essentially unaffected by the presence of the BON, test electronics and digital analysis unit.

Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE      In a so-called "scan-design" arrangement for testing integrated circuits, whether at the device level or at system level, problems associated with the storage and handling of vast amounts of data from increasingly complex devices are addressed by testing a pair of identical integrated circuits simultaneously and using the binary vector generated by scanning one of these integrated circuits as the reference against which to compare the binary vector produced by scanning the other integrated circuit.  A plurality of "scan-designed" integrated circuits may be connected in series, possibly in a ring, and each compared with its predecessor. zero-delay coupling across each device may be employed to allow each successive integrated circuit to be compared with the same reference circuit in the chain or ring.

Patent CA-1327714-C (CA)

Granted: 1994-03-15
Abstract: ABSTRACT OF THE DISCLOSURE    A fuel measuring system of the bubble type is adaptable for use with a plurality of tanks of predetermined differing geometries.  The system employs at least two bubbling tubes located at predetermined locations in a tank.  A predetermined volume flow of air is made to pass through each tube.  Pressure transducers are used to periodically measure the air pressures supplied to the bubbling tubes.  Temperature is also periodically sampled, and the pressure and temperature data is used by a microprocessor to make the necessary computations to first determine the averaged normalized air pressure and then the height of the fuel in the tank.  In order to correlate the computed value of fuel height with the actual quantity of fuel in the tank, the microprocessor accesses data in a table lookup memory for the particular tank and performs calculations in order to derive the instantaneous volume of fuel in the tank.  The instantaneous volume of fuel is then digitally filtered with two time constants, and the results of the digital filtering is used to determine whether fuel is being added to the tank at a rapid rate as in refueling or fuel is being drawn off the tank at a relatively slow rate as when fuel is being supplied to an engine.  Depending on the results of the test, an approximate, but stable, value of fuel volume is generated for display.

Abstract: ?MBER SELECTOR & MARKER                                 Page 39 Abstract of the Disclosure A number selector and card marker in accordance with this invention is usable in connection with the marking of a card or play slip, and it comprises a substantially flat housing having a slot therein for receiving at least a portion of the card. One part of  the housing has a series of closely spaced, carefully aligned holes of equal size, disposed in columns and rows.   The placement of the holes of the series closely coincides with the placement of rectangular boxes to be found in the game grids of the card to be marked.  An enclosure serves to enclose the series of holes as well as a plurality of small, equal size spheres.  Each of these spheres is slightly larger than the holes, so as not to be able to pass therethrough, the size relationship of the spheres to the holes being such that a small portion of each sphere extends below its respective hole when the spheres have settled into the holes.  A marking member is located in the housing directly below the series of holes and adjacent the aforementioned slot.  A marking device is slidably disposed in the enclosure, for applying pressure to the spheres when they have randomly come to rest in respective holes, the pressure applied to such spheres manifesting itself through the marking member so as to bring about the marking of the boxes of a card reposing in the slot, to make the card readily readable.

Abstract: In a fin-stabilized projectile (I) of a weapon, used to engage a tank (2) from above, the target end phase of the flight is initiated by a force on the nose of the missile body, in particular on the control unit that is located therein.  Because of the fact that the control unit (4) is rotating because of a target-detection sensor, during this rotary movement the projectile oscillates because of the gyroscopic effect and thus there are target deviations at different combat ranges.  In order to avoid the yaw angle and lateral deflections of the projectile that occur in the rotational-descent phase, within the projectile (I) between the control unit (4) and a warhead (3) there are means that impose a moment of momentum to the warhead (3) that corresponds but is opposite to the moment of momentum of the control unit (4).  These means are so configured that they are simultaneously suitable as a driving system to generate the rotation of the control unit (4).  According to a possible embodiment, gases from a pyrotechnic drive system, emerging tangentially from the nozzles on the warhead (3), cause a turbine wheel that encloses the control unit (4) and is connected thereto to rotate in the opposite direction.  The present invention also discloses the use of a mechanical drive means, such as, for example, the use of a coil spring or a threaded section in order to achieve an identical effect.

Abstract: An explosive powder charge operated tool for driving nails includes a housing with a muzzle part mounted in and projecting axially outwardly from the housing. By moving the muzzle part rearwardly into the housing, the tool is in the ready-to-fire condition. A magazine is supported at one end within the muzzle part and extends generally radially outwardly from it. A slide in the magazine feeds individual nails in a nail strip into the bore in muzzle part into position to be driven by a piston located within the housing. When all of the nails in the strip have been driven from the tool, one end of the strip projects into the muzzle bore. A stop shoulder on the one end of the strip faces toward an end face on the housing and contacts the end face when the muzzle part is pressed into the housing, preventing the placement of the tool in the ready-to-fire condition.
