Abstract: TITLE: CONVERSION FILTERING FOR DIGITAL    SIGNALING SYSTEMS        Inventor:  Michel T. Fattouche ABSTRACT          One way to increase the bandwidth efficiency of a linear modulation scheme is to increase the number M of possible signaling levels.  Such an increase is achieved however  at  the  expense  of  a  smaller  minimum  distance dmin between the multilevels for a fixed average signal power.   The  present  invention  involves  the  use  of  a conversion filter as part of a digital signaling system used over  a communications  channel  of  limited bandwidth and  power.   A  conventional  digital  signaling  system consists  of  an encoder,  followed  by  a modulator  and  a bandpass filter.   In  the  present  invention,  the digital signaling system consists of  an  encoder,  followed  by  a modulator, a conversion filter and a bandpass filter.  The conversion  filter  increases  the  bandwidth  efficiency offered  by  the  encoder-modulator  combination  when  the length  L  of  its  impulse  response  extends  over  several signaling  intervals.   Such  an  increase  is achieved, however,   at   the   expense   of   a   smaller   dmin.    By increasing  the  modulation  index  h  of  the  conversion filter,   it   is   possible   to   increase   dmin   without significantly  affecting  the  bandwidth  efficiency.   The invention also provides steps for choosing the modulation index  h  and  the  cutoff  frequency  fco  of  the  bandpass filter for a fixed length L of the conversion filing such that   dmin   is   at   least   locally  maximized   without significantly affecting the bandwidth efficiency.

Abstract: Abstract of the Disclosure An electrochemical cell comprising a relatively thin strip of anode material, first and second electrolyte layers coated on the opposing surfaces of the anode strip, first and second relatively thin strips of cathode material contacting the first and second electrolyte layers, thereby forming a laminate strip with the electrolyte layers and anode strip and a single cathode current conductor strip.          The laminate strip is deformed such that both of the first and second strips of cathode material contact the single cathode current conductor strip along substantially the entire length thereof.  In one embodiment, the cell takes the form of a spiral, in which the conductor strip is superposed to the laminate strip and the combination is rolled lengthwise, and in another embodiment, the cell takes the form of a stack in which the laminate strip is fan-folded and the conductor strip is fan-folded and inserted between the folds of the laminate strip such that the corners of the folds of the laminate strip are perpendicular to the corners of the folds of the conductor strip.

Abstract: ABSTRACT OF THE DISCLOSURE      A pin and box connection for connecting tubular members together utilizes a split sleeve.   The split sleeve is carried on one of the members and has the ability to retract.   This allows the members to be snapped together without rotation.  The split sleeve is threaded, and the threads ratchet over each other when snapped together.  A locking pin is located in one of the members for engaging a longitudinal slot in the other member.  The locking member prevents the members from rotating to unscrew once snapped together.   The locking pin can be removed to allow the members to be unscrewed from each other.

Abstract: PRIVACY NURSING BLANKET            ABSTRACT OF THE DISCLOSURE           The  invention  provides  a  blanket  which  can function not only as a blanket for keeping warm, but also as a blanket to provide privacy for a nursing mother to breast feed her baby in public and also as a sun shade and wind  shade.  The blanket  has  a  periphery  and  an  inner portion, and also a contracting structure for contracting the inner portion to form a hood means when contracted, the  contracting  means  being  spaced  inwardly  from  the periphery. A margin extends between the contracting means and the periphery and is adapted to form gathers or folds extending  from  and  around  the  hood  means  when the contracting means is contracted.  The hood means receives the baby's head, and usually most of  the baby's  torso. The  gathers  stiffen  the  margin  of the  blanket  to  be essentially self-supporting when extending from the hood means for leaning against the mother's upper body.

Abstract: An improved packing device which holds an article being shipped between membranes.  The membranes provide shock adsorption through their own resiliency and by allowing motion when forces in excess of the frictional limit are applied.          A pair of rigid frames and having central openings covered by an attached pliable material, form spacers which are forced in intimate contact with a fragile article within its shipping container to absorb shocks, flexion and torsion of the container due to shipping and handling loads.  The spacers can be a box-like structure with at least one open face covered with a flexible membrane.  The contour of the other faces of the structure are shaped and dimensioned to match the internal geometry of the container.  In some applications, the spacer structure is a wedge that fits in one corner of the container.          Two to four such wedges are typically used to support the object.  The framed membranes offer a versatile substitute for a variety of common packing inserts.

Abstract: An indirect lighting system having a generally visible light transmissive element, such as a prismatic lens element (31, 33) or a diffuser strip,  which modifies  the direction of  the  light incident thereon from a secondary light source,   The lighting system has a primary light source (13, 14) and structural means as in  a housing  (21)  for  positioning  the  primary  light  source proximate a reflective surface  (12)  which reflects light back toward the light transmissive element and which thereby acts as a secondary source of light for illuminating this element.  A light foil means such as vertical side reflector walls  (45,  47)  are disposed between the primary light source and light transmissive element for substantially blocking direct transmission of light to the latter from the former.   The light foil means, by keeping primary source light from directly striking the light transmissive element, forces the observable brightness in this element to be induced substantially entirely by the reflected light from the secondary source.
