Abstract: FMC 1709 ABSTRACT Peroxycarboxylic acids are prepared by the oxidation of a fatty acid with an excess of hydrogen peroxide in the presence of a strong acid catalyst. The yield is improved and the reaction time is reduced by intimately dispersing throughout the reaction mixture an inert water immiscible solvent for the peroxycarboxylic acid. The product may be recovered in crystalline form from the solvent phase.

Abstract: PROCESS FOR MAKING AMINE OXIDE     SOLUTION OF CELLULOSE                    Abstract of the Disclosure A process is provided for making a solution of cellu-lose in an amine oxide.  In accordance with one aspect of the invention, a solid precursor of a solution of cellulose in a tertiary amine oxide in the form of a chip or the like which has been prepared by suspending cellulose in a mixture containing a tertiary amine oxide and water is heated in the barrel of an extruder to dissolve the cellulose, and the resulting solution is extruded to provide an extrudate adapted to be shaped into a cellulosic product.  In another aspect, a tertiary amine oxide solvent for cellulose can be added directly to the extruder where mixing and dissolution take place under the application of heat and pressure.  It is further advantageous, in either case, where a non-solvent for the cellulose, compatible with the tertiary amine oxide and water, is employed.

Abstract: ABSTRACT An index card register with index card selector means is disclosed. The register includes a housing consisting of a cover member and a bottom member. A plurality of selector keys are disposed on the cover in an array of several rows and columns.  A  drawer of the register is biased by a com-pression spring and is adapted to be locked by n locking mechanism.  A plurality of index cards are accommodated as a stack within the drawer, the index cards including punched-out selector apertures in their rearwardly dis-posed marginal portions.  Each selector key is mounted on one end of an associated one-armed pivot lever which is resiliently urged unto an initial position by a spring and carries at its free end index card retainer.  The index card retainer cooperates with the index cards so that when a selector key is depressed all index cards overlying the index cards associated with this selector  key will be retained when the drawer moves outwardly from the housing whereas the selected index card and all index cards underlying the selected index card move outwardly together with drawer.  Means are pro-vided for unlocking the drawer and releasing the index card that has been selected by a selector key, by urging the unlocked drawer outwardly by means of the compression spring.  The drawer includes entrainment cams adapted to engage punch-out entrainment apertures in the index cards.  The index card register is characterized in that the selector keys are of a plate-shaped, square or rectangular configuration and are coupled to the pivot levers by vertical webs.  The selector keys disposed within a column, one behind the other, are of a width that corresponds to the overall width of the pivot levers mounting respectively these selector keys.  The selector keys are connected to the pivot levers so that  rearward selector key is cantilevered to the left with respect to its associated pivot lever and a forward selector key is cantilevered to the right with respect to its associated pivot lever.

Abstract: I.                   ABSTRACT OF THE DISCLOSURE      An air cylinder for supporting a moving web of material during heat treatment, particularly during drying, of such web.   The cylinder comprises a plurality of nozzles which axe arranged in a part-circular array around which the moving web passes the nozzles being of the Coanda type wherein the discharged gaseous medium flows over a transversely extended lip surface of the nozzle between the extended surface and. the adjacent surface of a web being treated and is caused to cling to such extended surface by the so-called Coanda effect, In order to support the moving web particularly stably in the radial direction relative to the cylinder, the nozzles are arranged in pairs, with the respective trans-versely extended surfaces of the two nozzles in each pair extending in opposite directions whereby air flowing over these two extended surfaces flows in opposite circumfer-ential directions to respective radially inwardly directed air outlets.   Each air outlet commonly serves two nozzles, one from each of two adjacent pairs of nozzles, respect-ively.     A plurality of the part-circular arrays of Coanda nozzles can be disposed with adjacent arrays inserted in relation to each other so as to support the materiel web in a circuitous path around such arrays.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for producing a deuterium enriched mate-rial by photo-induced dissociation which uses as the work-ing material a gas phase photolytically dissociable organ-ic carbonyl compound containing at least one hydrogen atom bonded to an atom which is adjacent to a carbonyl group and consisting of molecules wherein said hydrogen atom is present as deuterium and molecules wherein said hydrogen atom is present as another isotope of hydrogen.  The or-ganic carbonyl compound is subjected to intense infrared radiation at a preselected wavelength to selectively ex-cite and thereby induce dissociation of the deuterium con-taining species to yield a deuterium enriched stable mo-lecular product.  Undissociated carbonyl compound, depleted in deuterium, is preferably redeuterated for reuse.

Abstract: Abstract Cover Arrangement for a Container A cover arrangement for a container, for example for a ship's hatchway, has a cover element which is hinged at one side.  The hinging  includes a lost motion connection, which allows automatic engagement and disengagement of mutually engageable means at that side for cleating.  This is achieved by movement of the cover element in its closed position within the scope of the lost motion connection.  The cover element may include other automatic cleating means on other sides; the cleating is preferably effected by final closing movement of the cover element under gravity.

Abstract: APPLICATION OF: STEVEN (NMI) GEPPERT FOR: CRANE OPERATING AID AND SENSOR        ARRANGEMENT THEREFOR                      A B S T R A C T     A crane operating aid comprises a load moment computer and a number of transducers which monitor crane parameters such as boom length, boom angle, and boom reaction forces. The computer then calculates the percentage of load capacity as a function of the crane manufacturer's published load rating tables.  In cranes having booms which are luffed by a plurality of hydraulic lift rams, boom reaction forces are determined by providing separate pressure transducers on the lower or high pressure end of each ram.  The upper or low pressure ends of the rams are in fluid communication with one another, requiring only a single pressure transducer.  Each transducer generates an output signal as a function of the pressure which it is monitoring.  The signals from the transducers associated with the high pressure ends of the rams are averaged and the difference between the output signal of the transducer associated with the low pressure ends of the rams and the average signal is used to generate a reaction force signal.
