摘要： A Magnetic Resonance Imaging (MRI) phased array head coil (10) comprises an array of coils (1, 2, 3, 4) a decoupling circuit (7) and a decoupling base (14). Counter wound inductors from adjoining coils (1, 2, 3, 4) in the decoupling circuit (7) are interlaced to achieve mutual decoupling between adjoining coils. Each separate coil (1, 2, 3, 4) includes a pair of spaced parallel main conductors (12) located on opposite sides of a cylindrical space (5) enclosed by the coils (1, 2, 3, 4). The decoupling base (14) comprises two meandering conductor bases (8, 9) which are interlaced. Orthogonal main conductors (12) of the coil (1, 2, 3, 4) share a common conductor base (8, 9). The multiple crossings of the paths of the conductor bases (8, 9) reduces mutual coupling effects.

摘要： A coil for a magnetic resonance imaging device consists of multiple coil elements arranged about an imaging space. Each coil element comprise radiating structures oriented at an angle to a tangent of the imaging space. Angling the radiating structures reduces mutual coupling between coil elements and enhances the penetration of the radio frequency field to the imaging space.

摘要： A metering apparatus for liquids containing granular solids, in particular lapping liquid. The stream of liquid issuing from the feed pipe is conveyed with a wide area against a substantially vertical wall, to run down thereon in the form of a thin film of uniform thickness. The collecting pipe is arranged on the side of the wall which is remote from the liquid film. The wall has an orifice therethrough in its lower zone for the free end of the collecting pipe which extends obliquely upwardly. The collecting opening has a cross section which widens with progressive movement of the collecting pipe through the orifice.

摘要： Means for terminating the infeed of a machine tool, particularly a grinder. An electrode is imbedded within the tool and is exposed at the active surface thereof, such as the grinding surface of a grinder, and a sensing voltage is placed between said electrode and the workpiece. Suitable switching means is placed within the circuit of said electrode and workpiece which switching means will be activated upon the occurrence of a spark between said electrode and the workpiece. Activation of said switching means then activates further means to terminate the infeed of the tool. The circuitry supplying the voltage aforesaid may include a transformer having a plurality of output taps by which a plurality of voltages may be applied between the electrode and the workpiece and such circuitry will in such case include switching means automatically responsive to said different selected voltages. Thus, one voltage may be utilized at a first distance for terminating a rapid infeed, the occurrence of a spark at such distance then terminating the rapid feed, imposing a second and lesser voltage between the tool and the workpiece, and activating a creep feed and finally activating a switch sensitive to such second voltage which, when a second selected distance is reached, may be utilized to stop the power feed entirely.
