Abstract: ABSTRACT OF THE DISCLOSURE A mixer for mortar, plaster, fireproofing material and the like utilizing a plurality of mixing paddles supported from a horizontal shaft in a pivotal mixing drum.  Six paddles are mounted on the shaft and are oriented in a unique arrangement by which they rotate in a triple eight mixing action constantly dividing and recombining the mixture again and again thereby resulting in a smooth, uniform mix.  The paddles are provided with blades arranged so that material in the end of the drum is pushed half way to the middle of the drum by the first blade.  The second blade pushes material from the center of the drum halfway toward the end.  The next following blade then cuts the resulting pile into two approximately equal parts and pushes one part that has been cut from the pile toward the opposite end of the drum.  This action occurs simultaneously at both ends of the drum every time the paddle shaft revolves 360° and up to 50 cycles per minute depending, of course, upon the rotational speed of the paddle shaft.  The blades incorporated into the mixer provide an interrupted or staggered spiral which results in dividing, separating and recombining the materials which results in reduced rolling of the mix inasmuch as the interrupted force against the drum end will reduce the tendency of the mix to roll which is caused in a conventional mixer by the horizontal force on the mix being negated by the drum end so that all force will be exerted in a vertical direction.

Abstract: LIQUID TEREPHTHALIC ESTER POLYOLS            (D#80,319-F) Terephthalic esters may be made to remain in a liq-uid form by reacting recycled or scrap polyethylene tere-phthalate (PET) with diethylene glycol and one or more oxy-alkylene glycols and stripping out some of the ethylene glycol present.  The mole ratio of glycols to scrap PET should also be greater than 1.2:1.  This process keeps any diesters from separating out of the solution as solids.          These liquid terephthalic esters are useful as polyol ex-tenders in rigid polyurethane foams and as the sole polyol component in polyisocyanurate foams.

Abstract: METHOD OF MAKING A STENCIL PLATE    Abstract of the Disclosure A stencil plate is made by an electroplating process rather than a steel fabricating process.  A resist material and a film were placed upon a  matrix and by using conventional photoresist operations, a resist coating is formed on the matrix in the shape of the apertures to be formed in the stencil plate.  Metal is electroplated on the upper surface of the matrix and around the shaped resist material forming a stencil plate.      Subsequently, another resist coating may be placed over the first plated material and openings are formed in the second resist material.  Upon a subsequent plating operation, these openings are filled with a plating material and this provides a color dams structure around the openings in the originally formed stencil plate.

Abstract: ABSTRACT OF THE DISCLOSURE     In a transmission for an automotive vehicle, a control system for a direct-coupling mechanism for mechanically engaging input and output members of a hydraulic power transmission means.  Operating fluid pressure regulating means controls operating fluid pressure applied to a hydraulically operating portion of the direct-coupling mechanism, and the direct-coupling mechanism applies an engaging force corresponding to the operating fluid pressure thus controlled to the input and output members.  Vehicle speed sensor means detects the speed of the vehicle, and slip sensor means detects the value of a predetermined parameter indicative of an amount of relative slip between the input and output members.  When the detected vehicle speed falls between a first predetermined value and a second predetermined value larger than the first predetermined value and at the same time the detected value of the predetermined parameter is outside a predetermined range, control means causes the operating fluid pressure regulating means to vary the magnitude of the operating fluid pressure so that the predetermined parameter falls within the predetermined range.

Abstract: Abstract of the Disclosure PROCESS FOR THE SYNTHESIS AND PURIFICATION            OF DIISOPROPENYLBENZENE      Diisopropenylbenzene is a monomer that can be used in the preparation of many useful polymers and is also a chemical intermediate that can be employed in a number of chemical processes.  Diisopropenylbenzene is normally synthesized by the dehydrogenation of diisopropylbenzene.  Unfortunately in this dehydrogenation process a number of olefinic impurities are produced as by-products.  This invention discloses a process for the separation of diisopropenylbenzene from these impurities and for recycling some of the impurities.  In one embodiment of this invention this process comprises:  (1) dehydrogenating diisopropylbenzene to form a dehydrogenation mixture containing diisopropenylbenzene and organic impurities, (2) continuously distilling said dehydrogenation mixture to separate said diisopropenylbenzene from said organic impurities in a continuous recovery column 10, (3) fully hydrogenating said organic impurities to form a mixture of regenerated diisopropylbenzene and saturated organic impurities, and (4) fractionally distilling said mixture of regenerated diisopropylbenzene and saturated organic impurities under conditions sufficient to separate said regenerated diisopropvlbenzene from said saturated organic impurities.  The regenerated diisopropylbenzene can then be recycled for dehydrogenation with fresh diisopropylbenzene in the first step of the above described process.

Abstract: ABSTRACT OF THE DISCLOSURE:            In a three phase static voltage regulator com-prising a set of parallel-connected thyristor and diode between each phase R, S and T of a three phase supply source and the corresponding phase of a three phase load, a pulse is produced in response to each single phase source voltage passing by a zero amplitude where the voltage amplitude changes from a negative to a positive value.  A pulse is also produced in response to each such passage by a zero amplitude of the difference voltage between the phases R and S, which pulses are counted and digital-to-analog converted to produce a sawtooth signal of period To.  During each period To, the sawtooth signal is compared with a reference signal to produce a control pulse.  At the beginning of each control pulse, the pulses obtained from the difference voltage are applied to the gate of the thyristor interposed between the phase R and the corresponding phase of the load to turn the same on whereby a voltage is applied to the load.  After the latter voltage is detected, the pulses obtained from the single phase voltage of each phase  R, S and T are transmitted to the gate of the thyristor connected to this phase to turn the thyristors on and supply the load with power, until the control pulse ends.  In operation, the electric power supplied to the three phase load is adjusted by adjusting the width of the control pulses through adjust-ment of the amplitude of the reference signal.
