Abstract: A method of locating an underground utility line. A first step involves securing transponders along a length of an underground utility line at regular spaced intervals. A second step involves interrogating the transponders to receive transponder signals. A third step involves ascertaining the position of the transponder signals and extrapolating positioning of the underground utility line from the transponder signals.

Abstract: A method of dynamically tracking a location of one or more selected utilities. A first step involves providing a portable controller having a memory. A global positioning system (GPS) co-ordinate device and a display are coupled to the controller. A second step involves storing in the memory of the controller a series of GPS co-ordinates for the one or more selected utilities within an assigned service area of a municipality. A third step involves using the GPS co-ordinate device to dynamically provide GPS co-ordinates to the controller as positioning of the GPS co-ordinate device changes. A fourth step involves using the display to display the GPS co-ordinates of the GPS co-ordinate device on a scrolling display of GPS co-ordinates, together with the series of GPS co-ordinates for the one or more selected utilities, such that the relative position of the GPS co-ordinate device to the one or more selected utilities is always known.

Abstract: A method for determining positioning relative to utility lines. A first step involves providing a global positioning apparatus. A second step involves providing a processing unit with a display. The processing unit has stored in memory at least one geographical map depicting positioning of at least one utility line. A third step involves transferring data received from the global positioning apparatus to the processing unit and displaying on the display the positioning of the mobile machine relative to the at least one utility line on the at least one geographical map.

Abstract: An ink jet print cartridge having a compact electrical interconnect structure that includes a plurality of pairs of columnar arrays of electrical contact areas disposed on a rear wall of the print cartridge and electrically connected to ink drop generators arranged in primitive groups.

Abstract: A chandelier frame made from rings and spokes is provided. The rings are adapted for supporting ornaments, and the spokes are attached to the rings for supporting the rings, preferably coaxially. The rings and spokes are attached to one another by interengaging locking means which mechanically and detachably secure the rings and spokes to one another. The rings and spokes may be formed entirely from nonstressed metal, and most preferably are cut from flat sheet metal.

Abstract: The invention provides a two piece chandelier securable at two discrete positions. An upper and lower framework are moveable with respect to one another along a displacement axis and are securable in an access position and a decorative position, whereby access to an internal component of the chandelier such as a lighting element is facilitated in the access position relative to the decorative position.

Abstract: The present provides a new and improved apparatus for verifying the operation of a signature hopper of a collator. The hopper includes a rotary drum for transporting a signature from a storage bin to a feed location on a raceway having a moving conveyor. Two reflectors are secured to the drum. A first, miss reflector, is located so as to be covered by a signature during a normal feed operation. A second, miss verify reflector, is located so as not to be covered by a signature during a normal feed operation. An optical sensor directs a beam of light toward the drum and monitors for light reflected by the reflectors. A controller determines when the sensor should receive a reflected beam from the miss verify reflector. A warning signal is generated if no light is reflected from the miss verify reflector when it is expected.

Abstract: Apparatus for sensing a double thickness of a sheet-like product being conveyed past the apparatus by a feed device comprises a roll positionable adjacent the feed device. The roll has a perimeter partially defining a gap in the path of movement of the product. A support structure supports the roll for rotation relative thereto and for movement away from the path. A sensor senses movement of said roll away from said path. A caliper member is supported adjacent to the support structure. The support structure is mounted for adjustment to a position in which the gap has a width which is greater than the thickness of the product and less than the thickness of two products in response to positioning the product between the support structure and the caliper member. An adjustable member is movable to hold the support structure in the position to which it is move in response to positioning of the product between the support structure and the caliper member.

Abstract: A chlorine generating apparatus is disclosed herein by which chlorine gas or sodium hyperchlorite is generated in small quantities from a brine solution economically enough to be practical for use in the backyard swimming pool. The apparatus includes a free standing unit and cell utilizing only salt as its raw material to generate the chlorine required. The chlorine generating cell incorporates a chemical pump for forciably urging the resulting product to the pool without the use of mechanical pumps or membranes. A device is included whereby hardness minerals are prevented from being deposited within the cell.
