Abstract: ABSTRACT     Circuitry for causing the two wires of a seismic signal channel to appear balanced to hiline signal induced from surrounding power lines and equipment.  In this manner, the undesired differential mode hiline signal is eliminated from the channel and the common mode hiline signal on the lines may be eliminated by the input amplifier of seismic signal processing equipment.    The lines are balanced by a respective in-phase and quadrature phase components of a correcting signal that is a scaled version of the common mode hiline signal on the lines seismic channel.  The scaling is a function of the correlation between the hiline common mode signal and the hiline differential mode signal.  The system operates so that the correcting signal causes the differential mode signal and the correlating signal to go to zero.

Abstract: PRECIPITATION OR DEPOSITING OF PARTICLES FROM A SOLUTION                   Abstract The precipitation or depositing of particles from a solution in a cell in which an electric field is applied between an anode        and a cathode    typically an electrolysis cell for the co-precipitation of mixed oxides but also cells for electrodeposition or the electrophoretic deposition of colloidal particles, is controlled by measuring the pH of the solution in the cell using a probe shielded in a tube from the migrating electric current and from gas bubbles. The pH of the solution is then adjusted to a selected value as a function of the measured pH, e.g. by varying the electrolysis current or by bubbling in acid vapour, air or base vapour.

Abstract: FM AUTOMATIC GAIN CONTROL SYSTEM                         Abstract An improved automatic gain control (AGC) for a television transmission system comprising a transmitter for transmitting a TV signal via a transmission path to a receiver and having a certain bandwidth in which said transmitter includes a generator for generating a baseband TV signal which can be pre-emphasized and a variable gain amplifier responsive to the basehand TV signal to produce an amplified baseband video signal.  The AGC system comprises a band eliminating filter responsive to the baseband output signal to produce a first control signal -whose amplitude reflects the change in energy content of that portion of the TV output signal lying outside the allowed transmission bandwidth when said baseband signal is frequency modulated to a carrier.  The variable gain amplifier is responsive to the control signal to vary its gain substantially inversely as the out-of-band energy content varies.  At the receiver, a detector detects a component of the received TV signal which has known characteristics, usually constant, in the absence of the gain introduced at the transmitter.  The detector produces a second control signal which controls another variable gain amplifier to compensate for such gain and return the TV signal to its original form.

Abstract: ABSTRACT OF THE DISCLOSURE An automated acousto-optic tunable filter infra-red analyzer system useable in a variety of industrial and commercial control applications.  The system relies upon a narrow band pass  tunable acousto-optic filter which is selectively tuned by predetermined rf frequency signals to selectively  transmit  the narrow band pass  of interest which corresponds to  a  specific molecular  species  for identification and analysis.  The system includes a micro-computer and associated memory function to measure  and compare detected signals from an infrared detector which converts the filtered infrared signal  to  an electrical signal.   The  memory  provides  control  signals  for  the computer and for controlling the sequence and frequency of rf energy applied to tune the filter.  In this way, the near to mid range infrared can be analyzed for absorption bands  corresponding  to  predetermined  molecular species such as combustion product gases,  and a feedback signal generated to control the combustion process.

Abstract: FILTER DEVICE WITH MAGNETIC FILTER CLAMP                     ABSTRACT         The filter device is for filtering liquids and has a reservoir member for receiving the liquid to be filtered and a spout member for exit of the liquid after it is filtered, the spout member being assembled to the reservoir member with a filter disc therebetween.  Each of these members has an annular ceramic magnet, these ceramic magnets being adjacent each other when the members are assembled whereby the magnetic attraction sealingly clamps the filter disc between the members.  In accordance with the invention, the annular ceramic magnet of the reservoir member is completely enclosed within a closed annular cavity in the organic plastic of the reservoir member, the annular magnet being of smaller size than the annular cavity; and the annular ceramic magnet of the spout member is completely enclosed within a closed annular cavity in the organic plastic of the spout member, this annular magnet also being of smaller size than the annular cavity in which it is enclosed.  Hence, the ceramic magnets are protected by the organic plastic against chipping, cracking, corrosion or like deterioration but because they are of smaller size than the cavities there is room for expansion, without creation of stresses, when the device is heated in an autoclave as is sometimes required.

Abstract: A FURNACE PANEL FOR USE IN AN ARC FURNACE          Abstract of the Disclosure A furnace panel for use in an arc furnace is disclosed having a cast iron block with first and second surfaces and with a cooling circuit located therebetween.  The block has at least one anchoring member projecting outwards from its second surface for retaining the block to a wall of the furnace.  The panel further includes steel studs embedded in the cast iron block which project outwards from the first surface and which have a profile which enhances containment of molten slag against the first surface to prolong the life of the block.  As the molten slag is splashed onto the first surface of the block, the steel studs protrude outward similar to fingers on a hand, and catch the slag and retain it until it momentarily solidifies.  Once the slag has solidified, it acts as an insulating layer to prevent erosion of the block by the further impingement of additional molten slag.

Abstract: TITLE OF THE INVENTION          APPARATUS FOR COLLATING SHEETS OF PAPER          ABSTRACT OF THE DISCLOSURE:          Sheets of paper coming from an office machine such as a copier, are collated in a collator having a vertically extending sheet feeding channel.  Collating compartments forming a stack extend up  from  the channel at a slant.  Each collating compartment cooperates with its lower end with one or two sheet feeding rollers and a tiltable guide flap.  If a flap is in a passive position the respective transport roller, in cooperation with a counter-pressure roller, will move a sheet past the flap.  If the flap is tilted into an active position its curved shape will guide a sheet out of the feeding channel into the respec-tive collating compartment.  The tiltable guide flaps are so arranged that they extend on both sides of a horizontal plane and a vertical plane extending through a rotational axis of the respec-tive sheet feeding roller or rollers.  These features assure a sheet feeding free of troubles even if sheets of different lengths and of different thicknesses are to be collated.

Abstract: Abstract of the Disclosure A combined safety clutch and brake mechanism for a rotary lawn mower blade has a driven blade carrier with self-energizing centrifugal shoes biased to engagement with a driving drum.  Brake drum segments fixed to the shoes are engaged by a brake band which physically forces the shoes to declutched position.  To ensure reliable operation, the brake band is connected to a lever arm which is strongly biased to brake-ON position by a coil spring engaged about a guide rod and disposed along the movable end portion of the brake band, in a chordal position between the band and a surrounding protective bowl.  The geometry of the lever arm and spring thrust line progressively reduces the force required to actuate the brake band to OFF position, relative to the spring force, as the lever arm is moved and the spring compressed.

Abstract: AIR-CORE CHOKE COIL            ABSTRACT OF THE DISCLOSURE            An axially symmetric air-core choke coil for high voltage applications.  The coil includes a plurality of radially concentric, helically wound layers of windings. Non-insulated wire cable is used to produce each winding. therefore, adjacent turns of each winding, as well as adjacent layers are spaced from one another.  Separation between adjacent turns of each layer is provided through longitudinally extending, non-conductive, strips which are circumferentially spaced around the outer periphery of each winding layer.  The strips are folded radially inward at the open spaces between turns.  The layers are separated by a plurality of longitudinally extending non-conductive bars. The bars can be positioned to overlap the strips.  Numerous air gaps are thereby defined between adjacent turns and adjacent layers which allow air to easily flow in a radial direction into the center of the air-core coil.  A screen is provided at one axial end of the air-core and to direct the axial air flow over the inner periphery of the air core. This creates a Bernulli effect which reduces the air pressure within the air-core so that the radial air flow is substan-tially increased.  Means are provided for axially compressing the windings of the coil to increase its mechanical strength to withstand disruptive forces which develop during short-circuit conditions.
