Title: Automatic weather monitoring and adaptive transmitting system
Inventor: SIMON GARY B
IPC: G08C17/02
Filed: 1995-03-16
Granted: 2005-01-11
Abstract: A method for automatically providing weather advisories for an airport to pi lots comprises monitoring weather conditions at the airport and then generating weather advisories in response to these weather conditions. The broadcast traffic on a common traffic ad visory channel is also simultaneously monitored and then menus providing for select able weather advisories and radio check options are broa dcast to the pilots. The weather advisories or radio check can then be selected by the pilot by clicks of their transmit button. The time spacing between the menus is adaptively changed in response to traffic on the common traffic advisory frequency. Also, the length of the wea ther advisories is also changed in response to this traffic. The radio check opti on is provided automatically by first confirming selecti on of the radio check option and then allowing the broadcaster to broadcast a short me ssage which is recorded by the system and then rebroadca st.

Abstract: An apparatus for quickly and efficiently removing valve packing from a valve of the type having a threaded or non-threaded valve stem. In general, the apparatus includes a sleeve adapted to be positioned about the portion of the valve stem which extends exteriorly of the packing. The sleeve is rotatably connected to a translation mechanism operable in conjunction with the exposed portion of the valve stem. Depending on the type of valve and whether the exposed portion of the valve stem is threaded or smooth and whether or not the valve stem is capable of rotation, the translation mechanism can either be threadingly mated or clamped onto the valve stem to cooperate therewith for translating the sleeve toward or away form the packing. When the translation mechanism is operated, the rotatably connected sleeve is caused to translate along the valve stem. A plurality of curved teeth depend from the sleeve in such a manner that they all curve in the same rotational direction with respect to the sleeve. When the sleeve is rotated in that rotational direction and a downward force on the sleeve is applied by operating the translating mechanism, the teeth are forced to penetrate down and into the packing material. Once embedded, the translation mechanism can be operated in the opposite direction to apply an axial removal force to the sleeve and, hence, the teeth, thereby extracting the valve packing in which the teeth are embedded. Advantageously, since the sleeve is rotatable independently of the translation mechanism, the rotational force on the sleeve can be maintained or furthered to ensure the teeth remain embedded in the valve packing and to provide relative twisting motion between the valve packing and valve packing housing to facilitate removal of the valve packing. The teeth are readily removable and replaceable with different teeth or other implements for performing a variety of functions relating to removal of the valve packing, such as cutting, chiselling gouging, cleaning and polishing.

Abstract: Pipettes for infusing the uterus are disclosed, each pipettes being generally comprised of a proximal end, a mid-section and an enlarged distal tip. The proximal end has a coupling portion for engagement with a fluid-expressing syringe. Distal tips disclosed are of two primary shapes, one having a generally hemispherical distal zone of expanding diameter in a distal to proximal direction; and, another having a generally frusto-conical distal zone, with a similarly expanding diameter. Each tip also has a frusto-conical proximal zone, decreasing in diameter in a distal to proximal direction. One embodiment includes a generally cylindrical medial zone between its distal and proximal zones. The method of the invention includes using a guide hand in the anal canal above the cervical area to align the enlarged distal end of the pipette with the cervix;  driving the pipette through the cervix until a decrease in resistance is sensed; and, then pulling back on the pipette such that its enlarged distal tip effects a sealing action against the rim of the inner cervical opening. Once the fluid is infused into the uterus, the pipette is withdrawn.

Abstract: A roll fed labelling system and associated label are disclosed. The label (12) includes a triggering mark (28) formed of luminophor ink, i.e. containing a fluorescent optical brightening agent, that reflects visible light when irradiated with UV light. A modulated UV light is directed at the label and the modulated reflected visible light is detected and used to trigger a cutting mechanism to separate a single label from the remainder of the roll. The triggering mark need not visibly contrast with the surrounding graphics of the label and may be invisible in visible light. When producing the roll of labels, the amount of brightening agent may be controlled by monitoring the luminescence of the triggering mark relative to a reference level which may be derived with reference to a maximum luminescence of other parts of the label.

Abstract: A lip guiding mechanism is disclosed for use with a dock leveler having a deck which is pivotally movable with respect to a loading dock, a lip which is pivotally attached to a front of the deck, and a lip keeper which is positioned to receive the lip when the deck is in a cross-traffic position and the lip is in a pendant position. In use, the lip guiding mechanism selectively deflects the lip of the dock leveler away from the lip keeper to facilitate below dock level end-loading conditions. The lip guiding mechanism includes a lip guide member with a camming surface. The lip guide member is disposable adjacent to the loading dock and is movable between a stored position, wherein the camming surface is positioned for clearance from the lip of the dock leveler, and an activated position, wherein the camming surface is positioned for engagement by the lip of the dock leveler. When the lip guide member is in the activated position. the camming surface deflects the lip of the dock leveler away from the lip keeper of the dock leveler to permit the deck to be lowered into a below dock level position. The lip guiding mechanism is also provided with an actuator for selectively moving the lip guide member between the stored and activated positions.
