Abstract: IMPROVED ULTRASONIC IMAGE STORAGE DEVICE AND METHOD            ABSTRACT OF THE DISCLOSURE            An improved ultrasonic imaging system and method are provided for medical diagnostic purposes.  In order to store additional digital ultrasonic imaging information in a limited memory, a first digital signal representative of a video input signal is provided.  The first digital signal comprises a series of digital amplitude samples of the transverse component of the input signal.  A second series of samples is provided from the first series.  Each element of the second series is the arithmetic average of a group of elements of the first series.  Since the number of elements of the second series is less than the number of elements of the first series, memory density of the transverse component of the input signal is decreased.          The second digital signal series is companded to form a third digital signal series, the third digital signal series being stored.  The companding provides a third digital signal which is a non-linear function of the second digital signal such that the granularity of the stored signal is increased in regions of high diagnostic interest at the expense of decreased resolution in areas of low diagnostic interest.  When it is desired to display the stored digital image, the third digital signal is retrieved from the storage means and decompanded to provide the reconstituted second digital signal which is thereafter directed to a video display.

Abstract: ABSTRACT OF THE DISCLOSURE        A ligating clip is provided with first and second legs joined at their proximal ends by a hinge and terminating at their distal ends by a latch means for holding the clip latched closed when the legs are squeezed together.  One of the legs is provided with a base defining guide means for engaging portions of an instrument that may be used to apply the clip.  An instrument is provided to apply the clip and includes first and second handles mounted together for pivotal movement.  Each handle extends beyond the pivot axis to form a clip closing jaw.  The first handle includes a guideway for receiving a plurality of the open clips.  A pusher member is provided within the first handle to push the clips to the jaw region.  A spool is mounted for rotation in the first handle jaw and includes a forward flange and a rearward flange between which the front clip of the row of clips may be positioned. An L-shaped rod extends from the spool and is pivoted in one direction by one of the handles when the handles are closed to rotate the spool to permit passage of the closed clip from the jaws after the jaws are subsequently partially opened.  The rod is also pivoted in a second, opposite direction after the handles are partially opened to orient the spool to block feeding of the next clip beyond the jaw region.

Abstract: LAUNDRY SOFTENING DETERGENT A heavy duty laundering and textile softening detergent composition, in particulate form, useful for automatic machine washing of laundry in water, especially hot water, and readily dispensable from a charging compartment of an automatic washing machine (by action of water being fed through such compartment) includes a synthetic organic detergent, a builder for such detergent and a laundry softening proportion of bentonite, with which there is present a dispensing assisting proportion of a siliconate or similarly functioning derivative of such siliconate. In addtion to tending to inhibit firm adherence to the charging compartment walls of the bentonite, which is advantageously in separately agglomerated bead form, and promoting release thereof from such walls, the siliconate also aids in controlling the foaming activity of the built synthetic organic detergent and in strengthening the bentonite agglomerates. It also assists in stabilizing perfumes, dyes and bleaches, when such are present in the detergent compositions when it is employed in coatings for particles containing such components.

Abstract: ABSTRACT         "DEVICE FOR CONTROLLING GOLF SWING"       The present invention provides a golf swing aid which allows the user to practice a golf swing, including the hitting of a ball, so as to improve there style.  It has long been recognised that it is desirable to have the golf swing subscribe a mere circular arc within a fixed plane.          The angle of such plane might vary dependent upon a number of conditions such as the operators height and length of club being used.  The present invention provides a rigid elongate member with pivotable attachments at both extremities.  One pivotable attachment is constrained to the golf club shaft proximate its head.  The other pivotable attachment is fixed via a mounting means to a rigid point for example 6 feet above the ground level.  The pivotable nature of the two attachments and the rigidity of the elongate member provide geometric restraints upon the golf club while being swung and result in a near "perfect" golf swing.

Abstract: Abstract Location-representative signals are communicated to vehicles (12, 14, 16) by modifying existing traffic detector stations of the type utilizing an inductive coil (20) embedded in the roadway (22).  Circuitry (44-52) is provided for generating a carrier signal modulated in accordance with a modulating signal representative of the location of an associated traffic detector station.  A transformer (56) couples the modulated carrier signal into the existing inductive coil such that the coil establishes a magnetic field above the roadway which is modulated by the location representative signals.  The vehicles have inductive coils (703 mounted thereon for sensing the modulated magnetic fields, and circuitry (72, 74, 76) for extracting the location-representative signals therefrom.          The location-representative signals may then be, e.g., automatically transmitted to a central dispatching station (18).

Abstract: ABSTRACT A low-speed two-stroke diesel engine (12) is provided in the hull (22) and is connected to the propeller (16) via a line of shafting (21) for direct propulsion of the propeller.  A thrust bearing (15) secured in the hull (22) and taking the axial forces of the propeller is disposed in the line (21) between the propeller (16) and the diesel engine (12) and a coupling (14) allowing axial movements of the shafting portions connected by the same is provided between the bearing (15) and the engine (12).  The merchant vessel running costs are low because the direct propulsion eliminates transmission losses between the engine and the propeller, and because of the low specific fuel consumption of low-speed two-stroke diesel engines.  The thrust bearing protects the engine from the considerable axial forces of the propeller occurring during ice-breaking, thus simplifying the engine design.

Abstract: ABSTRACT OF THE DISCLOSURE     The color signals to be printed by a thermal color transfer printer are processed in order to provide gamma and temperature compensation for nonlinearities in the responses of the colored dyes used in the thermal printing ribbon and also to provide color compensation to correct for any over-lap in the spectral response of these colored dyes.  Color data signals are sampled and multiplexed to place the main or print color signal, which is determined by the color of the dye in position in front of the thermal head at that instant, in the center of a multiplexed, time-sharing arrangment with the non-print color signals arranged on either side.  The multiplexed signal is digitized and used to address a read only memory containing compensation curves to provide both gamma compensation and color compensation, and the compensated signals are adjusted in gray scale magnitude before being pulse width modulated for driving the thermal head to produce the desired color, hard-copy print.
