Abstract: FULL RANGE CURRENT LIMITING FUSE HAVING HIGH      LOAD CURRENT CARRYING CAPACITY                    ABSTRACT OF THE DISCLOSURE         A current limiting fuse is provided with a number of discrete current limiting elements coupled electrically is parallel between a pair of conductive terminals, and fused gap assembly in series with each current limiting element whereby full range fault current protection is provided by the fuse.  Under the influence of high range fault currents, the current limiting elements operate col-lectively to quickly clear the fault, while low fault currents are interrupted by fusing of the fused gaps to present a plurality of parallel arc gaps in the elements, which parallel gaps function in turn to sequentially distribute the full fault to each element resulting in successive interruption by the elements and ultimate clearing of the low range fault.  In a second form of the invention shiftable contact sets in each element are operably coupled with a low fault current responsive device to create the arc gaps required for sequential operation of the current limiting elements.

Abstract: FREQUENCY MEASURING APPARATUS Abstract of the Disclosure Frequency measuring apparatus wherein a single sideband modulator is fed by an input signal, the frequency of which is to be determined, and a reference signal having a predetermined frequency f0 to produce upper and lower sideband frequency signals separated in frequency by 2f0.  A delay line shifts the phase of one of such signals 0 relative to the other one of such signals, such phase shift being related to the frequency of the input signal.  The signals are then combined and detected to produce a signal having a frequency 2f0 and a phase angle related to the phase shift 0.  A phase comparator, responsive to the reference signal and the later produced signal, detects the phase of the later signal thereby providing an indication of the frequency of the input signal.  With such an arrangement relatively fewer and less costly devices may be used for the frequency measuring apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE           Test means, such as a composition or device, method of making a test device and process for determination of at least one oxidizing substance, such as a peroxide, are disclosed.  More particularly, the contemplated test means comprises a hydrazone and a hydroxynapthalenesulfonate selected from the group 4,5-dihydroxy-2,7-napthalene disulfonic acid (chromotropic acid) and 1-hydroxy-2-napthalene sulfonic acid.  Further provided is a test system for the determination of a constituent in a sample, having means responsive to the presence of said constituent in said sample to produce at least one oxidizing substance and a composition for deter-mining said at least one oxidizing substance, having the improvement wherein said composition comprises a hydrazone and a hydroxynapthalenesulfonate selected from the group of 4,5-dihydroxy-2,7-napthalene disulfonic acid and 1-hydroxy-2-napthalene sulfonic acid.  The test system is preferably of the type which determines peroxides formed from enzymstic conversion of constituents in biological fluids.  When in the form of compositions the test means can optionally be incorporated with a carrier, such as a tablet or matrix, to provide a test device.  The indicator system is highly sensitive to low levels of body fluid constituents to be detected while also being highly resistant to interfering reducing substances, such as ascorbic acid, often present in body fluids.

Abstract: ABSTRACT The present invention relates generally to a one-piece electrical contact fabricated from a single, integral piece of sheet metal.  Prior art connectors with standard contacts are not capable of withstanding severe environmental conditions while retaining good serviceability.  In connectors where environmental conditions have been considered, the con-tacts of such connectors, and the grommets in which they are inserted, may be damaged during installation, impairing the quality of the seal obtained.  This is particularly trouble-some with socket contacts having small resilient fingers or tines stamped from the body of the socket.  The present inve-tion overcomes these deficiencies by providing an improved electrical contact which is formed from a single, integral piece of sheet metal and includes an active contact element, a terminal element and a hood.  The hood covers at least the active contact element to protect the pin-engaging tines formed integrally therewith from inadvertent distortion or breakage.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention relates to a CTD arrangement comprising an input stage (ETS) which increases each of the input, signal-dependent charge quan-tities by basic charges (fat zero).  In arrangements of this kind, it is en-deavored to eliminate the influence of fluctuations in operating voltages upon the d.c. voltage component or d.c. component of the output signal.  The invention solves this problem in that a compensation stage (KST) which fully-eliminates the added basic charges is inserted into the CTD channel.  The sphere of application for the invention includes CTD circuits, and in partic-ular CTD transversal filter circuits.

Abstract: ABSTRACT OF THE DISCLOSURE A rotary power trowel having a safety clutch, a gyroscopic stabiliz-ing ring, blade pitch control, and an adjustable handle.  The safety clutch employs a belt tension adjustment to act as a brake on the drive belt when activated either manually or, in an emergency, automatically by a lever on a handle near the operator.  When the rotary trowel goes out of control in an emergency, centrifugal force activates the lever and disengages the driving force and acts to brake the belt in less than one turn of the handle.  The gyroscopic stablizer ring lowers the rotary trowel center of gravity and generates a stabilizing effect.  Blade tilting is accomplished through a turning knob located at the end of the adjustable handle, which is adjustable to the height of the operator.
