Abstract: 22.11.77 ABSTRACT     A  magnetic domain device comprises a first layer of a magnetic material for the formation magne-tic domains, for example bubbles, under the influence of a background magnetic field, which field is dis-posed transversely to said layer. There is provided a propagation structure with magnetically operating elements for driving the magnetic domains by the se-quential formation thereon of preferred positions for said domains. Drive means for the formation of a se-quence of preferred positions comprise a second layer of silicon with current conductors arranged thereon, so that the heat developed in the current conductors can readily be carried off by the silicon which ex-hibits a good thermal conductivity. In a first em-bodiment the current conductors are arranged so as to generate a rotary magnetic field in the plane of the first layer. In a second embodiment the current conductors are meander-shaped and arranged along a propagation structure for locally alternately at-tenuating and amplifying the background magnetic field. In a third embodiment the currents in the current conductors drive a so-called bubble lattice.          The said current conductors may also be employed for selectively creating domains and controlling them through switches, and for detecting and destroying domains.

Abstract: DISCRIMINATION OF BUBBLE STATE BY BUBBLE COLLAPSE          Abstract of the Disclosure A method for detecting the wall state of a soft bubble based upon the collapse characteristics of the bubble domain on a layer of bubble domain supporting material is described. The method includes the step of exchange coupling a magnetic layer, for example, an ion-implanted layer, to the bubble supporting layer.  An in-plane field is applied to the bubble supporting layer when Bloch lines are present in the bubble domains.  The bias field and the pulse field are set at a level to form a range of pulse widths which are suitable for the discrimination of soft bubble domains having different wall states.  A pulse is then applied for a time sufficient to collapse only the S=1 bubble and not the S=0 bubble. Thereby this method distinguishes S=0 bubbles having one pair of winding Bloch lines from S=1 bubbles having one pair of unwinding Bloch lines.  This method also distinguishes S=1 bubbles having a clockwise chirality from S=1 bubbles having a counterclockwise chirality.

Abstract: ABSTRACT OF THE DISCLOSURE              A nozzle for a jet stream in which the rear edge of the nozzle has a number of notches spaced there-along to widen the jet stream while directing the jet stream rearwardly of the nozzle.  Each notch has a narrow front apex and a rear opening substantially wider than the apex/ and each notch widens substantially smoothly and progressively from its apex to its rear opening, each notch having sides which at least over a major portion of their length diverge from each other at an angle of at least 60 degrees, and preferably at least 90 degrees. The nozzle will commonly blow into a diffuser to provide thrust augmentation but may also be used simply to blow over a flap, or it may be used without any diffusers or flaps, simply to provide noise reduction.  So long as the notch divergence angle is wide enough, loss of nozzle efficiency is minimized, and when a diffuser is used, thrust augmentation is increased.          In another embodiment, fairings are placed between the notches to guide and confine the flow to the notches, permitting a large reduction in the notch angle.

Abstract: J. T. Barnes et al 1-1-3-1 LUMINAIRE FOR RESIDENTIAL ROADWAY LIGHTING            ABSTRACT OF THE DISCLOSURE:         A luminaire for roadway lighting using a one-piece reflector developing at least two collimated beams in each longitudinal  direction.    The  collimated  beams  impinge on sloping faces of a refractor to diverge the beams into a regular pattern covering the street with a sharp cutoff at predetermined longitudinal distances from the luminaire.  The refractor employs a compressed parabola comprised of radial sections of comparatively large focal length with steps and risers.   The complex shape of the one-piece reflector may readily be produced by a reflector finish applied to a molded plastic matrix.  In the luminaire, the prismatic surfaces of the  inclined  walls  of  the refractor diverge  the formerly collimated beams in a carefully controlled manner to produce very uniform distribution of light.

Abstract: ABSTRACT      A method of locating an object by wave energy reflection and an apparatus therefor in which receiving outer trans-ducers  provide  directional  receptivities  represented  by polar lobes diverging on opposite sides of a reference axis and  an  inner  receiving  transducer  provide  a  directional receptivity represented by a narrower polar lobe centered on the reference axis.   The signals received from the outer transducers are operated upon in channels of the receiver to modulate them with a frequency swept local signal derived from the transmitted signal and develop indicator signals of difference frequency between the transmitted and received frequencies and which represent the range of the object.  The outer signals are displayed binaurally, to enable the user to achieve firstly approximate directional sensing by binaural effect, and thereafter more accurate directional sensing by the use of signals developed in a central channel and derived from the inner transducer or outer transducers simulating an inner  transducer.   Gain  in  channels  fed  from the  outer transducers is preferably adjusted as an inverse function of signal strength in the channel.  Higher frequency components are preferably accentuated in the inner channel to improve object character recognition.

Abstract: ABSTRACT      A method of determining flow velocities by measu-ring the phase difference between Doppler signals deri-ved from wave pulses and reflected by substantially the same reflector at two different times, the interval bet-ween the times being predetermined, a pair of electric signals being derived according to the method from each Doppler signal by modulation in quadrature, the signals jointly bearing  information relating to the phase of the Doppler signal, and a device for performing the method. In order to make full use of the possible measuring range, even at a relatively poor signal/noise ratio, at least a first and a second pair of signals (A, B and A', B' respectively) are combined to form a third pair of electric signals (Re, Im) which together bear an item of information depending on the phase difference between the Doppler signals. Mean-value signals (Re, Im) are for-med, each corresponding to the mean value of one of the third pair of signals, and an output signal which cor-responds to the mean value (.DELTA..PHI.) of the phase difference between the Doppler signals is derived from the mean-value signals.  It is particularly advantageous to use the method in an ultrasound diagnostic device for determining the velocity profile of a flow, more particularly of blood in a blood vessel.
