The invention relates to a loudspeaker combination comprised of at least two loudspeakers, of which one is preceded by a low-pass frequency filter, the other by a phase shifter in the form of an all-pass filter. The invention addresses the problem of providing with simple means a configuration simple of realization of such a loudspeaker combination, whose frequency response and whose radiation characteristic is significantly improved. The invention resides therein that the other loudspeaker or t...

A MIMO antenna (20) disposed on a substrate (10) including a first surface (102) and a second surface (104). The MIMO antenna includes a first antenna (20a) and a second antenna (20b) each including a radiating body (22a), a feeding portion (26a) electrically connected to the radiating body, and a metallic ground plane (24a). The radiating body includes a first radiating portion (222a), a second radiating portion (226a), and a gap (28a) formed between the first radiating portion and the second r...

A low bandwidth high brightness display system that utilizes a multiple beam cathode ray tube to write multiple rasters by concurrently scanning a plurality of lines with a selected number of beams. Each of the rasters covers a different portion of the screen so that the vertical deflection of the beam is reduced for each beam by a factor related to the number of beams. The system reduces the maximum data rate in writing speed relative to conventional arrangements with a resultant bandwidth redu...

A thermally responsive valve assembly comprises a plurality of fluid ports in which typically two are connected to vacuum sources, one to vent and another two to control functions. The switching of the control functions from vacuum to vent and back again is controlled by a bimetallic coil which rotates and, in turn, causes a switch disc to rotate thereby changing the passage route between the ports from vacuum to vent or visa versa.

A multiple pin connector for a multiple conductor cable formed of a housing having a face plate, a hollowed-out central area and a passageway to permit a multiple conductor cable to extend from the housing exterior into the hollowed-out central area wherein the housing includes a raised "U-shaped" collar having "U-shaped" collar ends terminating in a differential locking boss having a keyway which extends toward the other end of the face plate and with a clamping lip located on the exterior of t...

A multiple number of rotatable, axial flow turbine blades having a common platform and shroud portion from which two arcuately separated, axially extending, side entry roots protrude radially inwardly toward the axis of rotation of a rotatable shaft.

An antenna (10) suitable for multiple frequency band utilization includes three impedance elements (11,12 and 13). The second impedance element (12), which may also be called a network (12), includes a coil (L.sub.2) and at least one other conductor (17) in operative association therewith. The second impedance element may be electrically connected to both a first impedance element (11), which may include a linear conductor (14) coupled to a radio, and a third impedance element (13), which may in...

An improved hydrate store for a metal halogen battery system is disclosed which employs a multiple stage, multiple filter means or separating the halogen hydrate from the liquid used in forming the hydrate. The filter means is constructed in the form of three separate sections which combine to substantially cover the interior surface of the store container. Exit conduit means is provided in association with the filter means for transmitting liquid passing through the filter means to a hydrate fo...

Several sequences of radio-frequency and magnetic field gradients are presented for obtaining from a sample multiple response echo signals from which to obtain a plurality of independent angiograms, which can be combined or separately analyzed to provide more information than an individual angiogram, but in substantially the same amount of time as a single angiogram. For example, a series of angiograms, each with a different projection axis, can be obtained in the time required to obtain a singl...

A plurality of AC windings are disposed to share a common magnetic field circuit, to define a like plurality of electrically isolated, multiple-phase, stator windings on the same mechanical structure of an alternator. The plurality of multiple phase windings feed full wave rectifiers to supply a like plurality of outputs of selected voltage levels. Relay switching provides controlled output levels to loads of differing voltage requirements, regardless of unbalance in the loading of the plurality...
