Abstract: ABSTRACT Tripeptide derivatives having the formula    I   wherein H5 is a chromogenic substituted amino group which is capable of being split off by enzymatic hydrolysis to form a coloured or fluorescent split product H - R5. The tripeptide derivatives of formula I are used for assay-ing certain enzymes, more particularly factor Xa. Enzyme-bearing materials are reacted with the said tripeptide deriv?ives.  The quantity of split product H - R5  released by th? enzymatic action of the tripeptide derivative is determined photometrically, spectrophotometrically. fluor-escence-spectrophotometrically or electrochemically. The quantity of released split product H - H is proportional to the quantity of enzyme present in the starting materials.

Abstract: UNINTENTIONAL IMPEDANCE DETECTION SYSTEM              ABSTRACT OF THE DISCLOSURE     A detection system for detecting unintentional impedances between the power conductors and a first node of either a power conversion circuit or a load, the first node typically being an earth ground.  The circuit has power level lines utilizing a wye-connected line filter network which has equal impedance values for each leg of the line filter and which defines a first node at the common connection thereof.  A different impedance network is also connected in wye-fashion to the power level lines and defines a second node at the common connection there-of.  Each impedance leg of the impedance network is also equal in impedance value whereby the second node normally has the same potential as the first node.  The potential difference between the first and second nodes is fre-quency compensated to produce a system output signal indicative of a predetermined value of current in unin-tentional impedance between any of the power conductors and the first node.

Abstract: Abstract of the Disclosure A photopolymerizable monomer comprising a lipid having at least one hydrophobic acyl chain containing at least two conjugated acetylenic linkages is useful in preparing radiation-sensitive compositions and photo-graphic elements comprising a plurality of liposomes.          Further, processes for photopolymerizing the radiation-sensitive compositions and for forming an image in the photographic elements comprise exposing the lipid to radiation, heating the lipid to a temperature equal to or above a first transition temperature of the lipid to render it insensitive to further exposure, and optionally cooling the lipid to a temperature equal to or below a second phase transition temperature of the lipid to render it again sensitive to further exposure.  The monomeric lipids, when photopolymerized, form polymeric lipids exhibiting different solubility and liposome wall permeability as compared to the unpolymerized monomeric lipids,

Abstract: ABSTRACT OF THE DISCLOSURE    METHOD AND APPARATUS FOR MINIMUM KNOCK OPERATION OF AN   INTERNAL COMBUSTION ENGINE ON LOW KNOCK-RATED FUEL       The invention relates to method of, and apparatus for, operating an internal combustion engine on low knock-rated fuels as the primary fuel system in which engine knock is anticipated and suppressed by simul-taneously detecting actual engine load conditions that may induce such knock and knock condition that actually are occurring in at least one combustion chamber of the engine.  In response to such simultaneous conditions, a small but effective amount of anti-knock fluid is supplied to the engine combustion chambers in an amount and for a time sufficient only to suppress knock to a satisfactory level.  Such a system permits the use of more economic fuels, such as gasoline, having a substantially lower knock rating than those normally used in automotive equip-ment and only small but sufficient anti-knock fluid is added solely when the engine is knocking.  Such conditions occur over approximately 5-10 percent of road conditions and can readily be supplied by a 1-2 quart container of anti-knock fluid, such as higher knock-rated gasolines, alcohol or the like for each filling of the fuel tank with 10-20 gallons of less expensive low knock-rated gasoline to improve both economic and energy efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE               Apparatus for the shingling of cut sheets of paper as they pass between conveyance on a high-speed tape conveyor and and a low-speed tape conveyor is provided by means comprising a two-stage slowdown arrangement.  At the first stage, a slowdown mechanism, comprising two rolls arranged respectively above and below each sheet passing through a drop-off area from the high-speed conveyor to the low-speed conveyor, serves to engage the tail portion of the sheet in a nip such that the sheet is slowed down to a speed approximately 30 to 40% of the speed of the high-speed conveyor.  In this manner, the lead edge of a next succeeding sheet overlaps with the trailing edge of the nipped sheet in a drop-off area from the high-speed tape conveyor.  Downstream of the slowdown rolls is a stop roll which serves to reduce the speed of the immediately preceding sheet to the speed of the low-speed tape conveyor, which is still slower than the speed of the slowdown rolls such that the sheet passing through the nip of the slow-down rolls further overlaps with the immediately preceding sheet. The possibility of lead edge damage to the sheets engaging with a stop roll for shingling is effectively eliminated.

Abstract: ABSTRACT   An adaptive thresholder for processing image pixels. A portion of the image pixel line or lines is examined and the maximum and minimum pixels in the line portion determined. The maximum and minimum pixels are differ-enced, and the resulting difference signal compared to a constant representing the minimum desired change in background level. Where the difference signal is larger, a new threshold is thereafter used. To determine the new threshold level, the difference signal is multiplied by a factor representing the amount of change in threshold for a given event and the result subtracted from the previously determined maxi-mum pixel. The subtracted output is brought within predetermined maximum and minimum threshold constraints to provide the new threshold.
