Abstract: ULTRASONIC DIAGNOSTIC IMAGING SYSTEMS FOR VARYING DEPTHS OF FIELD            ABSTRACT OF THE DISCLOSURE            An ultrasonic diagnostic imaging system is described in which a multi-element transducer array transmits a focused beam of energy from the transducer elements.  As the depth of focus is varied between near and far field focusing under operator control, the nominal frequency of the transmitted ultrasound energy is varied correspondingly by the system, from relatively high frequency transmission in the near field to relatively low frequency transmission in the far field.

Abstract: ABSTRACT OF THE DISCLOSURE      Systems      and methods for detecting and eliminating latent          and existing short circuit current paths through photovoltaic devices of the type including at least one semicon-ductor region      overlying a substrate      and a layer of conductive light transmissive material overlying the at least one semiconductor region      are disclosed.  The latent paths are first converted to existing short circuit current paths by applying a bias voltage to the devices.  The short circuit current paths which are eliminated extend through the at least one semiconductor region      from the substrate to the layer of conductive light transmissive material,       The resistivity of the short cir-cuit current paths is increased substantially at the interface between the conductive light trans-missive material      and the semiconductor region by isolating electrically the conductive light transmissive material      from the short circuit current paths.

Abstract: Abstract Quadrature-related outputs of synchronized color reference oscillator at +(R-Y) and +(B-Y) phases are applied to a matrix to develop a third oscillatory signal of a third intermediate phase.  Additional operations on the oscillator outputs develop oscillatory signals of different phases symmetrically disposed about the third phase.  A differential amplifier, of substantially fixed gain, with differential inputs respectively responsive to the developed oscillatory signals, further develops a fourth oscillatory signal, with a phase in quadrature relation with said third phase, across an output load.  The reference signal input for a demodulator is derived from signals appearing across said output load.  A controlled amplifier, fed with the third oscillatory signal, is disposed to supply said third oscillatory signal as an additional oscillatory signal to said output load, when desired for hue adjustment purposes, with the magnitude of the supplied additional signal dependent upon the magnitude of difference, if any, between an adjustable control voltage and a reference voltage, and the polarity of the supplied additional signal dependent upon the sense of said difference.

Abstract: ABSTRACT OF THE DISCLOSURE         The device is used to connect electrical conduits together and comprises a male plug and a female receptacle, each of which has a housing with a central tubular component and a cavity extending through and adapted to receive an electrical conduit.  When the plug and receptacle are joined together an electrical conduit ends disposed in the plug and receptacle are electrically interconnected.  Both the plug and receptacle also include means for securing the conduits in place and sealing means for thermally sealing the conduits therein against atmospheric conditions.  The central tubular components are electrically insulative.          The male plug has a plurality of flexible fingers extending from the front end thereof while the receptacle has its tubular member dimensioned such that it splits the fingers as the plug and receptacle are joined together.  The receptacle tubular member has a plurality of recesses into which the finger ends snap to hold the plug and receptacle together.  Locking tabs slide over these recesses to lock the fingers in the recesses.  The fingers are retractable from the recesses, thus permitting uncoupling of the plug and receptacle, by sliding the outer sleeve of the recep-tacle rearwardly against an internal spring and carrying with it the locking tabs to a rear unlocked position.  The device is simple, durable and highly effective.  It is utilized in interconnecting nuclear reactor cable components and in other high temperature corrosive environments which require positive locking thermal and corrosion resistant connectors.  The device is also useful in high frequency electrical conductor applications.

Abstract: ABSTRACT OF THE DISCLOSURE In the optical connection of telecommunication glass fibres to semiconductors a novel curable lacquer is used which comprises a polyester-urethane-acrylate or a polyether-urethane-acrylate.  The lacquer furthermore comprises a heat- or light-activatable initiator.  The refractive index of the cured lacquer is adjusted by the addition of both a reactive diluent which increases the refractive index and a reactive diluent which reduces the refractive index.  Said reactive diluents furthermore serve to establish the desired mechanical properties of the lacquer prior to and after curing.  In the novel method, the curable lacquer is provided on the glass fibres and/or on the semiconductor laser, after which they are contacted with each other and are optically aligned.  The lacquer is then cured by raising the temperature or by exposure to light.

Abstract: ABSTRACT OF THE DISCLOSURE This invention refers to a locking device for a wear-parts system for earth moving machines.  The locking device consists of a rigid lock bolt connected to a lock catch which is intended to prevent the lock bolt falling out after it has been fitted in the lock opening for this purpose where it prevents the different parts of the wear-part from moving relative to each other. According to this invention the lock catch is designed so that it can be easily fitted in position together with the lock bolt and there provide the best possible locking action.  On the other hand no regard has been paid to the lock catch being able to be loosened from the outside in order to remove the lock bolt.  Instead a breaking point has been provided along the fixation of the lock catch in the lock bolt.  The breaking point makes it possible by means of subjecting the lock bolt to forces e.g., from blows with a heavy hammer, in the longitudinal direction of the lock bolt to load the connection between the lock bolt and the lock catch until it shears.  The latter remains in the lock opening when the lock bolt is forced out of the opening.

Abstract: ABSTRACT OF THE DISCLOSURE           An oil burner is of the type which enables controlling a degree of burning and performing fire extinguishing by vertically moving a wick.  The invention is directed to restricting the control of burning within a range of normal combustion, removing the restriction to manually perform fire extinguishing, and automatically performing fire extinguishing when vibrations are sensed by a vibration sensor.  The oil burner includes a slide shaft mounted on a wick shaft and a rotary member mounted on the wick shaft and enabling moving when axially pushed by the slide shaft.  The rotary member is interlocked with the wick shaft by an actuation member provided on the wick shaft, and is provided with a stop member which stops the wick shaft at a predetermined position in rotating in a wick lowering direction.  The rotary member is biased in the wick lowering direction by a spring which conserves resilience when the wick is elevated by operating the wick shaft, and is locked by a lock member in rotating in the wick lowering direction.  The locking of the rotary member by the lock member can be released when vibrations are sensed by a vibration sensor.

Abstract: ABSTRACT OF DISCLOSURE            The present invention concerns the dimensioning of a ground water well by investigating the yield characteristics of the ground water region. The object is, with the aid of the invention to obtain as correct data as possible for ground water well dimensioning, espe-cially when the water supply of a habitation centre or of an indus-trial plant is concerned. The initial exploration undertaken in the ground water area for well dimensioning purposes consists of pump-ing runs with an observation tube in the manner of stepwise pump-ing, using short time intervals (15 seconds to 20 minutes), and measuring the hydrostatic height of the water. In this way one finds the yield as a function of the level drop.  The yield of a well, compared with the yield of the observation tube, is found from the ratio of the strainer sections of well and observation tube, potentially with correction using an empirical factor due to the different size of the strainers. In the case of ground water deposits at very great depth, the yield may be explored by an inverted method in that water is pumped into the ground and the hydrostatic pressure is measured with different pumping rates.
