Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without disconnecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element.  The probe has at least two contact elements close enough to each other to simultaneously con-tact a led of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resistance of the lead segment, which current flow is indicative of the condition of the element.

Abstract: Abstract of the Disclosure An improved method is provided to cast a one-piece wheel having a circular hub and a plurality of airfoils.          The method includes providing a mold having a circular main section and a plurality of open-ended airfoil forming sections.  Each of the airfoil forming sections has a thick leading edge portion and a thin trailing edge portion.  During a casting operation, the mold is preheated while it is spaced from a chill.  The mold and chill are then moved into abutting engagement with the chill extending across the open outer end portions of the airfoil forming sections.  The relatively thick leading-edge portions of the airfoil forming sections are disposed adjacent to a portion of the chill.  Molten metal is poured into the mold cavity and flows outwardly through the airfoil forming sections into engagement with the chill.  This results in solidification of columnar grains of metal in a direction toward the center of the mold cavity.  As the molten metal is solidifying, heat is conducted at a greater rate from the relatively thick leading edge portions of the airfoils than from the relatively thin trailing edge portions of the airfoils.          Therefore, the columnar grains grow in a direction parallel to the central axes of the airfoils.

Driven side belts moving at the same speed contact the carcasses in the work stations and hold them steady against oscillation.  A saw or tool at each station is supported on a lead screw assembly for up and down movement.  The lead screw is di-rectionally and incrementally driven by a lead screw assembly at each station to locate each saw to perform work on the carcass.  The saws at each station successively cut off the shoulder, loin-belly and ham as the carcasses move, through the stations.  The shoulder, loin-belly and ham fall by gravity onto conveyers when cut off by the saws.          Manual means are provided to control the position of the saws as ob-served by the operator.  Automatic means include activating an intelli-gent vision camera at each station to identify the location of the de-sired work point on each carcass for each saw.  Camera data is calcu-lated against the last prior location of the saw and a signal developed and fed to the lead screw mechanisms to drive the lead screws to locate the tools or saws at the desired work points on each carcass at each station whereupon the carcass moves through the saw at each station at the desired paint of cut.

Abstract: ABSTRACT:     An output transistor (T1) to be protected, which transistor supplies a current (I0) to a load (3) is driven by a driver transistor (T2). The base-emitter junction of a current-sensing transistor (T3) is arranged in parallel with that of the output transistor (T1), the collector current of this transistor (T3) being a measure of the current (Io) of the output transistor (T1). A current generator (5) supplying a reference current (Iref) is coupled to the collector of the current-sensing transistor (T3). If the collector current of the current-sensing transistor (T3) exceeds the reference current (Iref) the protection circuit is activated in that the driver tran-sistor (T3) is bottomed via a transistor arranged as an emitter-follower (T4) so that the base current of transis-tor T1 is limited. Thus, the output current (Io) of out-put transistor (T1) is limited to a maximum value which is substantially equal to the product of the reference current (Iref) and the ratio between the emitter areas of the out-put transistor (T1) and the current-sensing transistor (T3).

Abstract: A B S T R A C T     Apparatus is provided for adapting an analog depth sounder for the calling out of the depth at regular time intervals. In one embodiment, a self-contained adapter module is mounted to the face of the depth sounder so as to cover the depth sounder display, with the module including a transparent plate carrying a detector array and with electronics and speaker carried at the center of the array. In this embodiment the detectors are arranged in thin radially extending lines to permit accommodation to displays of different diameter. Alternatively, small detectors are arranged along a circle having a diameter which overlies at least a portion of the orbiting radiating element which radiates along a considerable length.  This alternative array configuration also accommodates a range of display diameters.  As a further alternative, to accommodate different diameter displays. the thin line detectors may be replaced with radially extending light pipes with detectors at their ends.  The transparent plate with almost invisible detection apparatus permits viewing of the depth sounder displey through the plate so that visual as well as audible readout may be achieved.  Electronics is provided to decode the angular position of the orbiting element of the depth sounder at the time the element is actuated to provide a digital number repersenting depth. This number if then used in generating its speech equivalent through a standard speech synthesizer and loudspeaker.  The electronics may include a number of different ROMS or different sections of a single ROM to provide for scale adjustment. Alternatively, a variable rate clock may be used to adjust for scale. Alternative embodiments include sensing the time difference between pulses of electro-magnetic radiation from the depth sounder to establish depth, with the signals being available outside the depth sounder case. In each embodiment, signals which activate the speech synthesizer may be used to drive a digital display for improved filtering against spurious signals.

Abstract: ABSTRACT OF THE DISCLOSURE          A frazil ice concentration measuring instrument is described in which constant currents are supplied to a reference probe and sensor probe and used to generate voltages across the electrodes in these probes.  The sensing and reference voltages are amplified and compared in signal processing circuitry to generate an output voltage which is then integrated to give an average value of frazil ice concentration in a given time.  A heating system using oil as the heat transfer medium is used to supply and maintain the electrodes of the sensing and reference probes just above freezing to prevent ice accumulation on the electrodes.  The apparatus can also be used as general conductivity measuring instrument or for determining the concentration of a lesser conducting material in a more conducting liquid.
