Abstract: 118                47,802 ABSTRACT OF THE DISCLOSURE A programmable controller of the type used to solve relay ladder diagrams is taught. The programmable controller includes a memory into which is placed a digi-tal representation of  the rungs of the ladder diagram The dispositions of various switches and coils are period-ically  sampled  by  other  portions  of  the  programmable controller  and  stored  in  other  memory  locations.   At appropriate times between sampling intervals, the various memory information are combined and provided to a relay line  solver  which  comprises  part  of  the  programmable controller.  The relay line solver updates the status of the relay ladder diagram and restores the updated informa-tion in a memory.   This memory is used during the samp-ling intervals to change the status of output devices. The  programming portion  of  the  programmable  controller includes UP, OPEN and RETURN keys which may be manipulated by an operator in an appropriate manner for entering the ladder diagram initially into the programmable controller memory or  for updating or  changing  the  status  of  the various rungs of the ladder diagram. The entry keys are such that contact interconnection information is entered 119                47,802 into the memory at the same time and by the same keys that are utilized to enter the contact information.  This means that no separate memory words are required for contact interconnection information in the appropriate memory of the programmable controller.  Notwithstanding the afore-mentioned, very complex rungs of ladder diagrams may be entered using the three previously-mentioned keys.

Abstract: Abstract of the Disclosure A method of preparing large pore volume zirconia-silica catalyst supports, the resulting supports and a method of poly-merizing olefins comprising contacting an olefin or mixture of olefins with a catalyst prepared with these supports.  The supports are prepared by reacting a zirconium compound of the formula M4Zr(C2O4)4?nH2O , where M is an alkali metal or ammo-nium ion and n equals 0 to 10, with a silicon compound of the type A2SiO3 , where A is an alkali metal, in an aqueous solution at a pH equal to at least 11, then adding an acidic solution to a pH of about 5-9 to produce a hydrocogel.  The hydrocogel is then aged and washed free of soluble by-products first with water, then with aqueous ammonium nitrate and again with water.  The water is removed from the washed hydrocogel by azeotropic dis-tillation or by washing with a water miscible solvent and then calcining the resulting xerocogel.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to improvements in centri-fugal separators of the cyclone type, in which the liquid or gaseous fluid to be purified passes through an inlet blading which is sectioned so as to cause the fluid to rotate rapidly in so-called irrotational flow or regime with uniform longitudinal component, around high voltage electrode. An outlet device firstly comprises a convergent portion which partly converts the energy of rotation into energy of longitudinal translation, then a blading which com-pletes the conversion, and finally a divergent portion in which the excess of dynamic pressure of flow is converted into static pressure in order to recover as much as possible of the energy applied to the fluid upstream of the inlet of the cyclone device. The separated particles are evacuated through a tangential out-let The invention is more particularly applicable to the purifi-cation of fluids.

Abstract: ARRANGEMENT FOR ANGLE MODULATING A PHASE-LOCKED LOOP FREQUENCY SYNTHESIZER              ABSTRACT OF THE DISCLOSURE          Various arrangements for eliminating undesired side effects of modulation deviation within a phase-locked loop frequency synthesizer are presented. Angle modulation is simultaneously applied to two or more points within the synthesizer in order to eliminate the modulation distortion and side band power during modulation otherwise presented in the phase locked loop.  In the preferred embodiment, modulation phase shifts which would otherwise be coupled to one of the signal inputs of the loop phase detector are cancelled before they reach the loop phase detector.  Modulation is applied simultaneously to the loop voltage controlled oscillator (30) and a converting oscillator (52).  The output signal of converting oscillator (52) is mixed with the output signal of voltage controlled oscillator (30) by a mixer (54) to cancel modulation deviation before the loop signal is coupled to divider (36) and to loop phase detector (24).

Abstract: ABSTRACT A system and method for shearing pieces from bars, characterized by the normal positioning of a bar zone heating element such as an induction heating coil at one or a multiple of piece lengths in front of the bar shear. A bar feed incrementally longitudinally advances a bar one piece length at timed intervals through the heating coil to the bar shear, whereby localized areas or zones of the bar are heated at one piece length intervals. The heat received from the heating coil at each zone soaks into the bar to raise its core temperature as each zone is advanced from the heating coil toward the bar shear. After each incremental advance of the bar, a piece is sheared from the end of the bar at the then presented heated zone. Continuous automatic operation of the system is obtained by automatically detecting the remnant end of the bar, butting the leading end of a new bar to such remnant end of the old bar, automatically advancing the old and new bars together in the aforedescribed manner, and automatically moving the heating coil toward or away from the bar shear a distance corresponding to the length of the remnant piece of the old bar after the last zone of the old bar has been heated, whereby the zones of the new bar heated by the heating coil will be spaced at one piece length increments from the leading end of the new bar. The heating coil is automatically returned to its normal position when the remnant piece of the old bar is discharged from the bar shear so that the new bar is always heated at the desired incremental bar lengths.

Abstract: Abstract of the Disclosure A word processing system includes a voice recorder/player connected to the microprocessor of the word processor per se.  In use, a previously typed text is displayed on a visual display unit to the author who indicates by operating a remote switch that he wishes to provide instructions regarding the page of text displayed.          The microprocessor causes a unique burst of digital information to be recorded on the recorder identifying the page of text and the fact that an instruction is to be made.  Thereafter the computer activates the recorder microphone, allowing the author to insert verbally the desired instruction.  When annotation in this way is complete, the system is then handed over to the operator (typist) to whom the pages of text to be edited are displayed under control of the microprocessor which also causes the recorder/player to play back the appropriate voice instructions at the appropriate times.
