Title: Process for preparing improved lithographic printing plates
Inventor: WANAT STANLEY F
IPC: B41N3/04
Filed: 1994-09-27
Abstract: Provides herein is a brushgraining process to improve the quality of lithographic printing plate substrate surfaces. In the process, the surface is brushed in an aqueous slurry comprising a mixture of particulates of alumina and quartz in a weight ratio range 95:5 to 5:95, with the particulates being in the size range of 1-20 microns. Such a process surprisingly lessens the number of scratches produced on the substrate surface than when compared to using alumina alone or quartz alone or a mixture of alumina and quartz with particle sizes higher than the range disclosed.

Patent CA-2175575-A1 (CA)
Inventor: INCULET ION I
IPC: B05B5/16
Filed: 1994-11-04
Abstract: An actuator (20) for electrically charging an aerosol spray has an inductor (34) located adjacent to the spray nozzle (18) to induce a charge on the atomized fluid. Charge to the inductor (34) is provided by a piezoelectric crystal (46) which is stressed by movement of an operating member (26) to open the spray valve (16). Inductor charging utilizes negligible electrical power so that additional power sources are not required. The crystal may be stressed continuously such as by squeezing, or intermittently, such as by striking. When an intermittent stressing is utilized, the electrical circuit includes a switch between the crystal and inductor which is opened as the valve is opened to isolate electrically the inductor during spraying.

Title: Hierarchical system of locks and keys and key blanks therefor
Inventor: LINDSEY DAVID P
IPC: E05B35/12
Filed: 1996-06-21
Abstract: A hierarchical system of locks and keys with at least two distinct key slot configurations and at least two distinct  key blanks, each key blank being configured to enter only one of the first or second key slots.  The key slots include an upper portion and a lower portion, and the lower portion extends away from the upper portion at a predetermined angle.  The angles are different for each key slot and are selected so that the lower portions of the two distinct key slot configurations overlap, i.e., the upper portions thereof may be aligned such that the lower portions, which extend therefrom at different angles, define a common area of overlap.  The overlap area defines the configuration of a corresponding third key which will enter each of the other two key slots (and thus be a master key with respect to the first and second key slots).  In addition, the overlap area defines a third key slot configuration which may be used in an additional lock and will receive the third key blank but not the first and second key blanks.  This feature permits limiting the access of certain keys within one hierarchical system while increasing masterkeying capabilities beyond those of the prior art.

Abstract: The invention relates to a method and system for controlling a statistically multiplexed ATM bus (1), to the bus being connected a bus controller (6) and interface units (21-2N) for transmission of packets, i.e. cells, over the bus.  Having detected, for each cell to be transmitted to an ATM bus, the address of the interface unit participating in the transmission, the bus controller (6) sets the address on an address bus (1a) of the ATM bus (1), thereby activating transmission of the cell from the bus controller to the interface unit or vice versa over a data bus (1d) of the ATM bus. During the transmission of the cell, the bus controller (6) fetches the next interface unit address for transmission of the next cell from or to the interface unit concerned.

Title: System and method of improving the signal to noise ratio of bar code and indicia scanners that utilize fluorescent inks
Inventor: BERSON WILLIAM
IPC: G06K7/12
Filed: 1996-10-22
Abstract: A bar code and/or indicia scanning method that is able to determine what light was emitted from an upper layer invisible bar code and/or upper layer invisible indicia and what light was reflected back to the detector from avisible lower layer bar code and/or visible lower layer indicia. The detecting is "blind" to the spectra of the excitation source. Rather than differentiate between the exciter and emitter in the spectral domain, this invention differentiates between the exciter and the emitter in the time domain. The latency and persistence of the phosphorescent pigments of the invisible ink are used so that the detected signal is only the signal emitted by the upper layer invisible ink after the light source is turned off. Illumination and detection are synchronized to reduce the effects of reflection to zero so that the detector need not be chosen to be blind to the exciter. The foregoing is particularly suited to LED and laser illumination where the light source may be easily turned on and off.
