Title: Fuse link for a fuse cutout
Inventor: SABIS RICHARD J
IPC: H01H31/12
Filed: 1981-03-20
Granted: 1983-01-11
Abstract: ABSTRACT OF THE INVENTION An improved fuse link has a fusible element attached between first and second terminals. The first terminal is attached to, or integral with, a length of flexible stranded cable. The terminals, the fusible element and some of the cable are within an arc-extinguishing sheath. The cable is unified and stiffened for a selected distance immediately adjacent the first terminal to act thereat sub-stantially as a solid rod. The unified region acts as a guide for the first terminal moving through the sheath, reduces binding friction between the cable and the sheath, and eliminates "mushrooming" of the cable within the sheath.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of manufacturing a welded can body from tinplate or a tin-iron alloy plated steel sheet comprises overlapping the opposite marginal portions of a blank of the tinplate or the tin-iron plated steel sheet to form a can body preform having an overlapping portion, applying at least to the cut edges of the marginal portions of the blank a fluxing agent promoting wetting of steel with molten tin, and electrical resistance seam welding the overlapping portion in a nonoxidizing atmosphere by employing a pair of wire electrodes each covered by a layer of metallic tin on the surface thereof facing the overlapping portion.  The welded portion has improved corrosion resistance, as an extruded weld portion and a remaining cut edge surface portion thereof are covered with tin transferred from the surfaces of the wire electrodes and/or the tinplate during the welding operation.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a process for the recovery of elemental metal values from ores and processing liquids by solvent extraction-eletrowinning. The process involves extracting metal values by means of an aqueous strip solu-tion containing strong acid such as sulphuric or phosphoric acid.  The aqueous strip solution containing the metal values is used as electrolyte in an electro-plating process to electrowin the metal values.  A problem which has arisen is that oxygen evolved at the anode during electroplating entrains the strong acid electrolyte, to form a fine mist or spray which is corrosive and constitutes a health hazard.  In the present invention, the aqueous strip solution contains from 1 to 200 parts by weight of fluoroaliphatic surfactant, per million parts of strip solution, the surfactant having at least one cationogenic group which is the radical of a base having an ionization constant in water at 25°C of at least 10-6, and containing at least 30 weight percent fluorine in the form of carbon-bonded fluorine in a fluoroaliphatic radical, said fluoroaliphatic radi-cal having at least 4 carbon atoms and at least a terminal perfluoromethyl group. The invention inhibits or suppresses acidic mist formation above electrowinning tanks.

Abstract: CONTINUOUS RELEASE OF REAGENT IN AN ANALYTICAL      ELEMENT TO REDUCE ASSAY INTERFERENCE      Abstract of the Disclosure Analytical elements and methods for the selective determination of an analyte in aqueous fluids containing the analyte.  These elements and methods feature means for continuously releasing chromogenic indicator reagent from a reagent zone to a reaction zone.  The continuous release means is responsive to the application of a sample of the fluid to continuously release reagent into the reaction zone at a rate producing color response corresponding to interaction of the indicator with the analyte and reduced interaction of the indicator with interferents.  In pre-ferred embodiments, albumin is determined in the presence of interfering proteins such as globulins using buffered chromogenic indicator reagent.  In such embodiments, when protein interferents are present, their interference can be substantially eliminated for up to three minutes, dur-ing which time color response is substantially only from the interaction of albumin and reagent.  The determination of albumin follows from such color response.

Abstract: ABSTRACT:            Arrangement for modulating the output signal of a converter converting electric signals into other signals, for example optical signals. An analog signal is applied to a difference producer the output signal of which con-trols a limiter.  The binary output signal thereof con-trols the semiconductor laser diode which is coupled to a photo-sensitive detector for producing a feedback signal. After having been amplified in a broad-band amplifier and integrated in an integrator, this feedback signal is applied to the difference producer, in which the feedback signal is subtracted from the analog signal. Variations in the optical output signal due to a non-linear conversion characteristic of the laser diode and due to an optical retroaction of the fibre on the laser diode as well as out-put noise and signal-dependent amplitude variations are reduced by the negative feedback.

Abstract: FREQUENCY SHIFT KEYING DEMODULATORS          Abstract of the Disclosure: In an FSK demodulator, the output of the phase detector of a phase locked loop (PLL) is capacitively coupled to one input of an FSK voltage comparator, the capacitive coupling blocking d.c. and d.c. being restored at the comparator input by diodes connected between the two comparator inputs.  The other input of the comparator is supplied with a reference voltage corresponding to a nominal center frequency of the FSK signals.  A buffer amplifier permits rapid charging of the coupling capacitor, which is set to a determined state when there is no phase lock of the PLL.  The arrangement facilitates demodulation of narrow-band FSK signals whose center frequency is subject to change.             - i -

Abstract: ABSTRACT OF THE DISCLOSURE           A surgical cutting intrument that is particularly adapted to lift individual ones of sutures from the skin of a patient and to hold each suture by means of a knot at one end thereof while cutting the suture to free it from the skin.  The instrument comprises a longitudinally extended body having a generally straight handle portion at one end and a pair of tines at the other end.  Both tines are up-turned and are of unequal length with blunt innermost edges defining a narrow slot open at one end to snare the knot of a suture.  The tine ends are blunt and rounded, the longer of which is insertable under the suture.  A longitudinal sharp,thin cutting edge, which comprises a replaceable steel blade in a polycarbonate plastic embodiment, is disposed along a portion of the outermost edge of the longer tine ad-jacent the junction of both tines and the body.  Rotation of the handle brings the sharp edge into cutting relation with the suture which is then severed and removed by lifting the knotted end held fast between the two tines.

Abstract: BALL TYPE UNIVERSAL JOINT AND METHOD OF MANUFACTURE   Abstract of the Disclosure A ball type universal joint construction where a ball member is rotatably received in a housing and a bearing structure interposed therebetween in a manner which limits the relative rotational degrees of freedom.  The ball member has a spherical surface portion which includes axially extending bearing receiving slots and the housing has a cavity spherical surface portion which includes bearing receiving recesses in registry with the receiving slots.  Ball type bearings disposed partially within the recesses and partially within the slots limit movement between the ball member and housing to articulated movement relative to each other.  The housing also includes an access opening at one end face having an enlargement through which the ball member can be passed when rotated 90 degrees to its nominal, functioning position.  This allows the ball member to be inserted into the housing through the enlargement while at the same time accommodating passage of the bearings into the housing recesses.  Thereafter, the ball member is further rotated such that the receiving slots also partially receive the bearings and thus capture the ball member in an articulating, non-rotatable relationship in the housing.
