Abstract: IMPROVED COOXIDATION PROCESS FOR THE PRODUCTION OF DIMETHYL TEREPHTHLATE                 Abstract of the Disclosure Disclosed is an improvement in the cooxidation process for making dimethyl terephthalate (DMT).  In the cooxidation process an oxidate comprising monomethyl terephthalate and p-toluic acid is esterified with methanol to form a reaction mixture comprising DMT and methyl p-toluate, methyl p-toluate is separated from the reaction mixture, and p-xylene and said methyl p-toluate are cooxidized in the liquid phase with mole-cular oxygen to form more oxidate, which is esterified, etc. The improvement comprises separating p-toluic acid from part of the oxidate prior to esterifying the oxidate, and cooxidizing separated p-toluic acid with said p-xylene and said methyl p-toluate.  This improvement results in a lesser quantity of oxidate subjected to esterification, and a reduction in the quantity of methyl p-toluate cooxidized with p-xylene.

Abstract: Abstract of the Disclosure Frequency doubled television receiver horizontal deflection frequency signals are divided in a divide-by-525 counter to produce pulses at the vertical deflection rate. The five hundred twentieth pulse of each 525 pulse series is used to enable a bistable multivibrator which produces an enabling signal on an "and" gate.  The five hundred twenty-fifth pulse of each 525 pulse series produces a resetting signal on an "or" gate.  The fifth pulse of each 525 pulse series removes the enabling signal from the out-put terminal of the bistable multivibrator thereby inhibiting the "and" gate.  The vertical sync pulse appearing between the five hundred twentieth pulse of each 525 pulse series and the fifth pulse of the next succeeding 525 pulse series passes through the enabled "and" gate and synchronizes the operation of the vertical deflection circuit.  The vertical deflection sync pulse is also coupled to the "or" gate to reset the divide-by-525 counter and synchronize its oper-ation to the incoming vertical sync.

Abstract: METHOD OF PREPARING STABLE CONDENSATION PRODUCTS   USING A WATER-ALKYLENE OXIDE TREATMENT AND PRODUCTS THEREFROM     Abstract of the Disclosure Products which are phosphorus containing oligomers having   linkages between phosphorus atoms and which are obtained by the self-condensation of.beta. -haloalkyl esters of pentavalent phosphorus acids or the condensation of these esters with alkyl esters of a pentavalent phosphorus acid are treated after residual acidity has been neutralized, e.g., with an alkylene oxide,with water and then with an alkylene oxide for a period of time which is sufficient to enable the water to open labile groups contained in the product and the alkylene oxide to neutralize any further acidity generated by the opening of such groups.  The stabilized product formed by this process when incorporated in a polyurethane foam gives a foam having superior green strength to a polyurethane foam which is not treated in accordance with the invention.

Abstract: ABSTRACT OF THE DISCLOSURE   A lawn mower is disclosed, having a novel cutting arrangement.  The mower has a housing with an open bottom, and a blade carrying rotor mounted within the housing.  The blades are disc cutters, mounted in pairs on the rotor by means of support members themselves pivotally mounted on the rotor. One blade of each pair has a driving shaft that projects upwardly from the support member and carries a roller at its upper end.  Upon rotation of the rotor, the support members swing outwardly under centrifugal force until the rollers come into contact with a ring mounted on the underside of the housing top wall.  This contact drives the roller, its shaft and the associated blade. The other blade has a shaft that is biased with an appropriate spring to bring the two blades into overlapping contact.  Thus, rotation of the one roller causes counter-rotation of the other.

The dried aggregates are there-after crushed, calcined and rapidly quenched.  It is preferred to dry the slurry in a spray drier and thereafter omit crushing after drying and to calcine the dried admixture by means of a plasma arc so that the mixture is rapidly quenched after calcina-tion.  The calcined mixture is introduced into a crusher, such as a ball mill, with a carbonaceous cellulating agent and reduced to a fine pulverulent material.  The pulverulent material is then cellulated in a cellulating furnace to  form cellular borosilicate bodies.  Where desired, the calcined material may be utilized as a ceramic frit.
