Abstract: ABSTRACT              A distance amplitude compensation system is disclosed herein for comparing received signals with a reference signal having a time varying amplitude.  The preferred embodiment of the invention disclosed herein is particularly adapted for use in an ultrasonic nondestructive testing system to vary the reference signal of the system as a function of time to compensate for variations of the echo signal produced by changes in the amplitude of the ultrasonic energy as it propagates through the workpiece as a result of attenu-ation or other causes.  A pulser/receiver transmits ultrasonic signals into the workpiece, receives echo signals returned therefrom and produces received signals corresponding to the echo signals.  A

Abstract: PRESSURE COOKER             Abstract of the Disclosure:       A pressure cooker has a cover which is removably secured in pressure-tight relation to the cooker body.  The cover has a centrally disposed valve which regulates pressure development in the cooker and an over-pressure release plug in the cover margin adjacent the cover handle which separates from the cover in reponse to excessive pressure development in the cook-er and is captivated by an overhang portion of the cover handle which directs the escaping fluids away from the hand grip por-tion of the cooker handles.  The cooker also has an interior-located pressure-actuated interlock in the margin of its cover opposite the cover handle which inhibits removal of the cover when the cooker is in a pressurized condition, and prevents pressure build up in the cooker when the cover is incompletely locked to the cooker body.

Abstract: ABSTRACT OF THE DISCLOSURE             An improved low-energy detonating cord, which is light-weight, flexible, strong, and non-conductive, detonates at high velocity, and is readily adapted to high-speed continuous manufacturing techniques, has a continuous solid core of a deformable bonded detonating explosive composition comprising a crystalline high explosive compound, preferably superfine PETN, admixed with a binding agent, the crystalline explosive loading being about from 0.5 to 10 grains per foot (0.1 to 2 grams per meter) of length; and, enclosing the core, a protective plastic sheath, e.g., about 0.005-0.075 inch (0.127-1.905 mm) thick, no metal or woven textile layers being present around the core or sheath, Preferably, one or more continuous strands of reinforcing yarn e.g., running substantially parallel to the core's longitudinal axis, are located between the core and the plastic sheath, or in or around the sheath.  A prefered cord can be made by drawing strands of yarn under tension in the form of a moving cage of substantially parallel strands, allowing the moving cage to entrain a bonded explosive core within it and thereby form a conveyor for the curve, and applying a layer of plastic material around the cage while effecting sub-stantially no change in the diameter of the explosive core after its entrainment within the cage.

Abstract: ABSTRACT OF THE DISCLOSURE:            An improved isobasic double-recycle process is disclosed for synthesizing urea with the formation of ammonium carbamate as an intermediate, comprising effecting reaction between ammonia and carbon dioxide at high NH3:C02 molar ratios, a heat-treatment of the synthesis product at sub-stantially the same pressure as that of the synthesis step and in the presence of a stripping gas, and two distinct isobaric recycles of the residual substances and of the substances in excess released from said synthesis product, said process being characterized in that: (a) said heat-treatment of the synthesis product is carried out in two consecutive stages which are isobaric or substantially isobaric with respect to the synthesis step, in the first of which stages said synthesis product is heated, whereby substantially all the residual smmonium carbamate is decomposed and the decomposition products are displaced together with part of the excess NH3, while in the second stage the remaining part of the NH3 excess is displaced by supplying supplemental heat and by injecting thereto a C02 stream; and (b) the gas phase stripped in the first stage is immediately recycled to the synthesis step and the gas phase stripped in the second stage is subjected to a condensation and to a residual gas purge and then recycled, in the liquid state, to the synthesis step.  The synthesis temperature may range from 170° to 205°C, the synthesis pressure from between 100 and 250 Kg/cm2, and the NH3: C02 molar ratio during the synthesis from 2.5:1 to 10:1.

Abstract: ABSTRACT           An organic product material having a high nitrogen and phosphorous content is produced as the product of a biological system for the treatment of a BOD-containing influent which also contains phosphorous and fixed nitrogen.  The biological treatment system comprises the reaction of a mixed liquor composed of an activated biomass and a BOD-containing influent initially under anaerobic conditions and thereafter treating such mixed liquor under oxic conditions.  The treated material is them separated into a supernatent liquid in which the BOD is depleted and a dense, activated biomass.  A portion of this biomass is employed in forming the mixed liquor for the initial anaerobic treatment, while the remaining portion of the biomass is recovered as product. The living biomass product can be used in the fermentation indus-tries.  Alternatively, the product can be used as such or further processed, e.g. dried, for employment as a fertilizer or a nutrient in animal feeds.

Abstract: ABSTRACT       A dispenser for wound rolls of flexible sheet material, such as, paper towels, toilet tissue or the like has inwardly facing tracks on the opposite inner side walls of the dispenser housing to receive therein outwardly projecting spindles carried by wound rolls to be dispensed for the rolls to move in succession downwardly relative to the tracks with a section of the lower end of each track slanting away from a feed roller mounted adjacent the lower end of the dispenser housing and each track having at such lower end section a pivotally mounted roll rotation driving guide biased toward the track center to form the lower side of each track section slanting away from the feed roller. A pressure roller is biased into rotating engagement with the feed roller for flexible sheet material to drivingly pass therebetween with the pressure roller having at least one resiliently deformable segment that is eccentric to the pressure roller axis to pick up the leading free end of sheet material on a full roll and lead it into the nip between the feed roller and pressure roller, this pressure roller also has axially spaced conical resilient portions along the length thereof with the conical portions facing from the opposite ends of the pressure roll inwardly toward the mid-point of the pressure roll to promote spreading out the sheet material passing between the feed roller and the pressure roller. A serrated cutting knife is pivotally mounted within the feed roller to sever the sheet material, the serrations on the knife being spaced to accommodate therebetween the deformable eccentric segment and the conical portions on the pressure roller during initial projection of the knife from within the feed roller in severing the sheet material. The cutting knife swings about an axis laterally displaced from the plane of a radially outward portion of the knife and cam followers are carried by the ends of the knife extending beyond the ends of the feed roller with the followers displaced from the pivot mounting axis of the knife. Stationary cams are mounted adjacent the ends of the feed roller with which the cam followers on the knife edge engage to positively project the knife cutting edge beyond the feed roller periphery and retract the cutting edge upon rotation of the feed roller.
