Abstract: Abstract The subject matter of the present invention is a method and apparatus to determine the trace and depth of metallic conductors (6) located beneath ground level.   The substance of the method is that ferrite antennas (16,16') are matched to coupled parallel os-cillating circuits the capacitive element of which provides resonance frequencies equal to the (cp ? 1)-th, preferably (cp - l)-th and cp - th, or (2c ? l)-th, preferably (2c - l)-th and 2c-th upper harmonic of the basic frequency of the alternating current, where c is a properly selected integer higher than 1, the value of p is 1, 2, 3, or 6 as required, while cp is an even number, thereafter the trace of the conductor (6) is localized by detecting the vertical component (5) of the magnetic field at an upper/lower level and the horizontal component (4) at a lower/upper level, on the basis of the ratio of the two components the trace is approximated to a certain extent, then in order to measure the depth (4) of said conductor (6) the hori-zontal component (4) of the magnetic field is detected both at the upper and the lower level and the depth (4) is determined by the known formula.   The apparatus com-prises an upper and a lower ferrite antenna (16, 16') at least one of which can be rota-ted in the vertical plane.   By means of the method and apparatus provided by the present invention the trace and depth of conduc-tors conducting an alternating current can be determined with a high selectivity and accuracy.

Abstract: APPARATUS AND METHOD FOR LOCALLY          HEATING CONVEYED GLASS SHEETS                   ABSTRACT         An improved apparatus including a local-ized heater that moves along the direction of con-veyance with conveyed glass sheets to provide localized heating of a portion of each glass sheet to be bent without heating the rest of the glass sheet prior to its subsequent treatment.  This in-vention is especially suitable for locally heat-ing designated portions of glass sheets as they are heated while being conveyed through a furnace on a horizontal roller conveyor where the desig-nated portion of glass sheets are to be formed with bends having relatively short radii of cur-vature at a bending station.  The apparatus inclu-des a pair of elongated localized gas heaters, each of which is positioned above the portion of the glass sheet which requires significant bending.          These heaters are mounted on a carriage driven by a drive mechanism.  The drive mechanism causes the carriage to move along a path parallel to the path of glass sheet conveyance to allow the heaters to continuously heat the designated portions of the glass sheet between an upstream position and a downstream position of the carriage.  After the carriage reaches its downstream position, the drive mechanism causes the carriage to return to its up-stream position in preparation for another cycle.

For this purpose the exhaust gas is introduced as a fluidizing gas into a fluidized bed which consists of two solid fractions differing in particle size, namely, a coarse-grained fraction having a particle size dp 50 in the range of 150 to 500 µm and a fine-grained fraction having a particle size dp 50 below 10 µm.  The coarse-grained solid fraction consists preferably of CaO, CaCO3, MgO, MgCO3, dolomite and/ or sand and the fine-grained solid fraction consists of Ca(OH)2 and respectively amount to 70 to 90 % by weight and 10 to 30 % by weight of the entire fluidized bed.  A gas velocity of 1 to 10 m/sec and a mean suspension density of 0.2 to 2 kg/m3 are preferably maintained in the fluidized bed reactor.

Abstract: ABSTRACT A television receiver comprises a digital signal processing system that develops an analog signal for displaying a picture from a digitally supplied information signal.  Binary coded digital samples are processed by a first processor, operating at a first rate, to develop a first data stream.  The samples are also processed by a second processor, operating at a second rate faster than the first rate, to develop a second data stream.  An interpolator inserts interpolated signals into the first data stream to produce a modified first data stream having the second data rate.  Combining means combines the modified first and the second data streams, to produce an output data stream.  An analog to-digital converter generates an analog signal from the output data stream to display the picture on an image display device.

Harrow attachments intended for use with shovels on shank type cultivators are generally not adapted for use behind one way rotary disc type cultivators in that such harrow attachment do not have provision for forced pivotal lift-ing of the harrow relative the shovels on shank type cultivator frame.   Such pivotal lifting is particularly suitable for harrow attachments to be used on one way rotary disc type cultivators because the frame of a one way rotary disc type cultivator is generally not vertic-ally movable with respect to the field surface.   The present harrow attachment advantageously can be provided with a journalling device for attachment on the rocking shaft  generally  provided  parallel  the  discern  frame.          Furthermore linkage can advantageously be provided which links movement of the gang lifting mechanism so as to provide  simultaneous  lifting  of  a  discer  gang and harrow.

Abstract: TUNABLE VISCOUS SPRING MOUNT           Abstract A viscous spring damper particularly adapted for supporting an automobile engine is provided.  The damper comprises a first fluid chamber including a first wall portion defined by an elastomeric journal and a second fluid chamber including a second wall portion defined by an elastomeric diaphragm.  A restrictor plate is inter-posed between the fluid chambers and includes a main fluid port and an auxlliary fluid port for communicating fluid between the cham-bers.  First and second elastomeric flaps are oppositely disposed about the main fluid port.  The flaps are selectively tensioned and spaced from the restrictor plate to seal the main fluid port against fluid flow upon deflection of the flaps against the port in response to a preselected shock amplitude and frequency. The flaps are inde-pendently tensioned and spaced from the restrictor plate to possess the capability of having distinct natural frequencies and to seal the fluid port upon distinct amplitude deflections and frequencies during damper compression and rebound. The main fluid port is sized so that the flaps may be receptively deflected into the port upon sufficient compression of a fluid chamber to substantially limit the pressure in the chamber.
