Abstract: Abstract of the Disclosure A traveling unit which has instrumentalities for reinstituting attenuated strand formation at drafting systems of a textile yarn forming machine and which traverses a textile yarn forming machine having a plurality of drafting systems is controlled by an arrangement which facilitates reduction in the number of ineffective attempts at reinstitution of strand formation.      The control arrangement includes an active sonic detector for electrically signaling traversal of a drafting system location at which a stop number is in a retracted position and an attenuated strand detector responsive to electro-static charges normally present at drafting system locations during attenuated strand formation.  The control arrangement distinguishes among three possible circumstances and initiates operation of the instrumentalities for reinstituting strand formation only as required.

Abstract: APPLICATION OF:     JOHN J. SASENA            FOR:     FASTENER FOR FENCE          CONSTRUCTION AND FENCING SYSTEM UTILIZING SAME.             ABSTRACT OF THE DISCLOSURE            A one-piece spring fastener is provided for mounting fencing wire or the like to a channel shaped support.  In one embodiment the wire is mounted generally perpendicularly  to the support and is free to move along its axis relative to the support.  The fastener is of a generally "U" shape  in cross-section comprising two generally parallel, spaced apart, generally "T" shaped members joined along substantially the entire tops thereof by a bight or interconnecting bridge portion.  The top portions of the "T" shaped members in combination with the bight portion form a trough for receipt of the wire and the base portions of the "T" shaped members are generally dart shaped for non-rotational, forced receipt inbetween and retention by the inturned flanges of the channel shaped support.  Projections on opposite ends of the top portions are designed to engage opposite, parallel, exterior surfaces of the support when the dart shaped base portions are retainingly engaged between the inturned flanges to prevent rotation of the fastener relative to the support.

Abstract: ABSTRACT OF THE DISCLOSURE           A spark ignition circuit begins producing sparking pulses and a storage capacitor begins charging upon closure of a space thermostat.  An electromagnetically operated valve controlling gas flow to a burner is energized sufficiently to open only upon discharge of the capacitor and a parallel holding circuit holds open the valve and prevents recharging of the capacitor.        A counting circuit, including a first monostable multivibrator, responds to each sparking pulse to effect incremental charging of a capacitor.  Circuit means, including a programmable unijunction transistor and a second monostable multivibrator, responds to each occurrence of a predetermined charge on the capacitor to produce an output pulse comprising negative and positive signal voltages occurring in that order.          Switching means responding to the positive signal of the first occurring output pulse effects the discharge of the storage capacitor and completion of the holding circuit, whereby the valve is open.  If timely ignition occurs, means responding to burner flame cuts off igniter operation.  If ignition does not occur within the following counting period, the switching means responds to the negative signal of the succeeding output pulse to break the valve holding circuit.

The mixture is then added in a continuous manner to a bath containing such solvent, and is distributed therein. The rolling mill scale is the slowly moved out of the solvent containing bath while mixing the rolling mill scale with an oil-free solvent of the above mentioned type passed in counter-current flow to the last mentioned mill scale. The movement of the thus obtained last mentioned mixture is continued while causing the solvent to drip off out of the grease-free rolling mill scale. The rolling mill scale is then heated, and the residual solvent driven out of the rolling mill scale. Finally, the grease-containing solvent is regenerated by distilling the same, and the oil-free solvent is condensed and fed back to grease-covered rolling mill scale to be de-greased.

Abstract: ABSTRACT OF THE DISCLOSURE       In one embodiment the main water valve to an irriga-tion system is connected by a fulcrum arm to a float chamber with a float therein operatively connected to the arm.  When the water is "on" a controlled feed gradually fills the float chamber which shuts off the water when the float chamber is full.  At this point a controlled bleed valve in the bottom of the float chamber gradually emptys the float chamber and turns on the water when the float chamber is emptied thus tim-ing the "on" cycle and the "off" cycle.  By closing the control-led feed and fully opening the bleed valve, the water level in the ground can raise and lower the float so that irrigation is by soil moisture content rather than by time.  In another embodiment the water in the float chamber raises and lowers air pressure in a sensing tube which acts upon a diaphram which in turn is operatively connected to the fulcrum arm.  Once again the actuation can be on a time basis or by the moisture content of the soil.

Abstract: ABSTRACT OF THE DISCLOSURE         A porous lightweight particulate aggregate for use in concretes, mortars, building blocks and other building elements, comprises expanded and vitrified low alkalinity particles of a material composed of an alkali metal silicate having an M2O/SiO2 ratio of from about 1:2 to 1:4 wherein M is an alkali metal; silica in an amount of from about 0.1 to about 50% by weight of said alkali metal silicate; and an alkaline earth metal silicate in an amount of from 0.1 to 200% by weight of said alkali metal silicate, said particles having a density of not more than about 60 g/dm3 and a com-pression strength of up to about 275 kg/cm2 and having an expansion ratio of up to 15 times their original collapsed volume.  Suitable fillers and additives may be added to said aggregate to provide specific and useful properties for a variety of uses thereof.         A process of manufacturing a porous lightweight particulate aggregate comprises kneading an aqueous slurry of an alkali metal silicate, finely divided silica and a finely divided alkaline earth metal silicate, in order to form a homogeneous mixture, reducing said slurry to parti-cles of a preselected size depending on the desired size of the finished aggregate, gradually raising the tempera-ture of said particles to from about 110 to about 700°C, and then firing until a temperature of from about 700 to about 1500°C is achieved and vitrification of the silicates is completed.  Potassium nitrate may be added to provide for the formation of a large central pore to produce a hollow particle structure on heating the   mixture.         The gradual increase in the temperature may be partially carried out in the presence of saturated steam in order to humidify and to therefore render the surfaces of the particles sufficiently plastic, whereby a hollow structure having a central large pore surrounded by a shell of highly porous material is obtained.

Lateral guidance windings are provided on the lower arms of the magnet and the lower pole faces slope to the horizontal, in the lateral direction of the track so that, at a track junction, by energising appropriate windings, the vehicle is guided to a selected track.  The lower arms are longer than the upper arms to give, as a result of the leakage flux, lateral damping.

Abstract: Abstract of the Disclosure The present invention relates to the production of water-moistenable adhesive coatings and to products incorporating such coatings.          A two-stage process for applying such coatings to wallcoverings and the like is known.  In this process, a water-insoluble resin copolymer, in which at least one monomer is an acid, is deposited and subsequently neutralized upon the substrate.  This process suffers from many disadvant-ages, including the need for excessively high application weights, hazards to equipment and operators, and excessive penetration of the copolymer into the substrate resulting in incomplete neutralization thereof by the subsequently applied alkali.  In the present invention, these problems are avoided by neutralizing an acidic copolymer to form a salt thereof before applying such salt to the substrate.  The salt may then be applied in various ways, such as from an aqueous or organic suspension or in a dried powderous form.
