Title: Charge director compositions for liquid developers
Inventor: ALMOG YAACOV
IPC: G03G9/135
Filed: 1990-07-24
Abstract: A liquid developer system for use in electrostatic imaging processes of the positive toner type comprises toner particles micro-dispersed in a carrier liquid and at least one charge director compound soluble in the carrier liquid, wherein the total amount of charge director compound is associated with the toner particles and essentially no charge director compound is present in the carrier liquid. Especially useful charge director compounds are those which have been reacted with at least about one molar equivalent of at least one acid containing at least one organic moiety, the acid being effective in that the reacted positive charge director compound increases the short-term charging of the micro-dispersed toner particles as compared with charging when the same molar amount of unreacted charge director compound is used. Positive charge director compounds reacted with acid are e.g. those of the general formula RSiX3 wherein R is a hydrocarbon radical, one or more of the hydrogen atoms of which may be substituted by halogen atoms, and X is halogen or lower alkoxy; the reaction products with acid of the compounds RSiX3 are believed to be novel.
Patent CA-2061292-A1 (CA)
Inventor: BERNARDINI BERNARDINO
IPC: G11B5/86
Filed: 1992-02-17
Abstract: The present invention falls within the technical field of devices for the duplication of industrial magnetic tapes.          More particularly it relates to an electronic device for the fast duplication of magnetic tapes.  The device, through a microprocessor, activates selecting circuits to control static memory cards of a memory bank.  The selecting circuit generates proceeding signals and selecting signals which single out memory cells of the memory bank for writing and reading.  These selecting signals and proceeding signals cause a subdivision of the cards in the memory bank, allotting a part of the memory for reading and another part for writing.  The selecting and the proceeding signals are carried out through digital signals.  The final digital signals are subjected to a digital-to-analog conversion.

Abstract: A folding ramp replaces the tailgate of a pickup truck. The ramp has two congruent rectangular panels joined by knockdown hinges. The inner panel is pivotally attached to the truck just as the tailgate was. The two panels relatively rotate between an extended planar disposition for use as a ramp and a folded or sandwiched position for use as a replacement gate. The inner panel includes hardware for pivotal attachment to the bed, for latching to the ends of the sidewalls of the truck bed, and for clamping the two panels together when in the gate position. The hinges have removable pins, so that the two panels can be separated;  the inner panel can then be used alone as a hate. For trucks with step bumpers, the inner panel may include an extension, comprising a cross bar pivotally attached to the truck, and two parallel telescoping arms slidingly inserted into the side members of the inner panel. The arms bridge the width of the step bumper and remain horizontal; the two panels slope down to the ground from the ends of the arms.

Abstract: To prepare an initial portion on a replacement roll (4) of a substrate web (41), for example a printing paper web, for flying pasting, the new roll (4) is rotatably supported in a predetermined position. An adhesive application and cutter structure (5) is then placed in operative association with the roll. An initial portion of the web (41) is rolled off from the new roll, positioned on the support plate, and, in one operating step, an end, which may be jagged, is cut off and, inwardly of the cut edge (42), a perforating or tear-off line (43) is formed, to leave, between the cut edge and the tear-off line, a tear-off section (44). The web can then be repositioned on the plate (6) and a connecting adhesive (19) is applied to the upper side of the web, for subsequent flying pasting against a moving expiring web, for example, as well as a holding adhesive, applied in the inside of the tear-off section (44), so that the end portion of web (41) is securely attached to the roll. Preferably, the cutter and perforating blades are located on a single support block; and the adhesive applicators, likewise, are retained on a common support structure, which may be coupled with the blade support structure, for conjoint movement across the web.

Inventor: DUBOIS JACQUES
IPC: G01S3/785
Filed: 1992-06-18
Abstract: A laser warning receiver (LWR) having an ability to not only detect a low power level laser source, such as a pulse train emitted by a laser beam rider, but to also provide a high angular resolution in determining the angle of arrival of that pulse train. The receiver includes a lens/filter arrangement for a large area photodetector to detect an incoming signal from an emitting source and a high gain amplifier to amplify the signal which is then applied to a synchronization generator that generates a digital pulse train with pulses corresponding to peaks in the incoming signal. The digital pulse train is applied to a code breaker where the code is analyzed and a further code is generated anticipating the arrival of further pulses in order to verify the code. That further code is applied to a time gate generator which generate a code, synchronized with the incoming signal, that controls the high voltage of a gated image intensifier which is coupled to a video camera. Gating of the image intensifier is synchronized, as a result, with coded emissions from the source so that a video image from the camera can be displayed on a monitor and more easily differentiated from the background. The width of pulses generated by the time gate generator, the video camera, gain of the gated image intensifier, gain of the gated image intensifier and an auto-iris zoom lens coupled to the image intensifier are all under the control of a video processor.
