A hand held dispenser of hot water intended for weed control purposes has a handle containing a hose connection, a flow regulator, a heating tube, an exit tube, a nozzle and a power switch. The handle is connected to a tube which contains a main electric water heating element surrounded by a tube through which water can flow form the bottom of the wand towards the handle before being piped through an exit tube to the nozzle. A temperature sensor is positioned adjacent the handle to regulate the power supplied to the heating element.

An electric coil is printed onto a flexible sheet so that it can be bent into any desired shape to create a complex magnetic field. A flexible parallelogram substrate, having a two-coil pattern printed thereon, can be bent into a cylinder so that the coil pattern at the ends of the cylinder generate an axial magnetic field while the remainder of the coil pattern on the cylinder can generate a transverse field varying continuously through 90.degree..

Electronic arrangement for detecting and identifying individual balls in a table ball game involves the use of two or more distinct code elements embedded in the balls. When applied to a pool table, the balls landing in the pockets are conveyed by inclined ducts to an electronic detector coupled to a scoring device. The detector recognizes the resonant frequency of each code element and compares the codes detected with the combination of codes assigned to the different balls. The application of the invention to Kelly Pool and Poker Pool is described.
