Abstract: VERNIER ADDRESSING APPARATUS                           Abstract A vernier address scale reduces the number of addressable memory locations required for numerical look-up tables.  Read-only memories (ROMs) store the data of linear or non-linear functions.  Decoders determine which ROM is selected and advantage is taken of accuracy improvement as numbers become larger by dropping least significant bits as the vernier address scale moves from one ROM table to another.  Accuracy is further improved by using a method of one-half level quantization step for rounding.  This reduces the size of numerical tables for math processing of reciprocals, roots of numbers, powers of numbers, logarithms, trigonometric and exponential functions.

Abstract: ABSTRACT         In a device for receiving leaking liquid for use in a ship carrying low temperature liquid or corrosive liquid in self-standing tanks, a frustoconical, umbrella-shaped leaked liquid diverting means is disposed around the root of a tank supporting block of the self-supported tank so as to direct liquid, which has leaked from the tank, to a heat insulating and protective member or a reservoir which is mounted below the outer periphery of the leaked liquid diverting means.  This prevents the extremely low temperature liquid or corrosive liquid from directly contacting the bottom of the ship's hold.  The problem the invention seeks to overcome is damage to a ship's structural steel caused by highly corrosive or extremely low temperature liquids which comprise the ship's cargo.  Prior to this invention the alternatives were to either construct a ship of expensive special steel or provide a double insulating jacket. Both of these alternatives are extremely uneconomical.  The present invention provides a low cost, efficient alternative.

Abstract: METHOD OF QUANTITATIVE ANALYSIS OF SUBSTANCES AND           NUCLEAR-RESONANT QUANTITATIVE ANALYZER THEREFOR                    Abstract A method of quantitative analysis of substances based on nuclear magnetic resonance comprises the steps of weighing a sample of substance to be analyzed, obtaining therefrom and accumulating nuclear magnetic resonance signals during n measuring cycles, computing a mean value of the nuclear mag-netic resonance signals, and determining percentage of com-ponents in the sample being analyzed with regard to its mass and the mean value of the nuclear magnetic resonance signals. The mean value of the accumulated signals and its standard deviation are computed as the accumulation occurs during each of the n measuring cycles, the subsequent step being subtraction of the standard deviation form the per-missible limiting standard deviation value whereupon the accumulation is topped during the ?ith cycle in which a difference between said magnitudes is a positive value.     A nuclear-resonant quantitative analyzer for accomplishing the aforesaid method comprises a magnetic system, a nuclear magnetic resonance signal pick-up arranged in its gap, an amplifier, a selector and an analog-to-digital converter, which are connected to the output of said pick-up, a video--pulse generator connected to the input thereof, and a radio--pulse generator. The analyzer also comprises an automatic sample weighing unit composed of such series-connected compo-nents as a weight-to-frequency converter, a load-receiving platform thereof being inserted in the nuclear magnetic reso-nance pick-up, and a frequency-to-code converter, a data swapping unit, a processor, a control unit, a pro-gramming unit  and a  data  output unit.

Abstract: ROCKER-RECLINER CHAIR     ABSTRACT OF DISCLOSURE.        A rocker-recliner chair including a base, rocker cams mounted on the base, a unitary seat and armrest assembly mount-ed on the rocker cams by a novel linkage system for movement between a closed or generally upright position with the asso-ciated footrest closed, a TV position wherein the footrest has been extended and the seat inclined relative to the rocker cam, and any one of a number of advanced reclining positions where the footrest remains extended and the backrest has moved relative to the seat while the seat has moved relative to the rocker cam.  When the chair is in the TV or any advanced reclining position, a "rock-blocking" mechanism prevents forward-rearward rocking of the cams relative to the base, however, the cams are permitted to rock rearwardly to permit movement of the seat into advanced reclining positions.  In the preferred embodiment, actuation of the footrest to the TV position is initiated by means of a handle positioned on one side of the chair.  This opens a release mechanism to allow the chair to be moved to TV position through the weight of the occupant of the chair.

Abstract: SPECIFICATION            RELAY STRUCTURE                ABSTRACT OF THE DISCLOSURE A relay structure advantageous for compacting purpose is disclosed herein.  The relay comprises a generally L-shaped yoke having an upright yoke leg and an upper yoke member extending substantially at a right angle thereto, the upright yoke leg being connected to one end of the core of an energizing coil which extends substantially in parallelism with said upper yoke member.  The upper yoke member is formed with a center slot extending longitudinally thereof to be open at both longitudinal ends.  A generally L-shaped armature is hingedly supported onto the free end of the upper yoke member with a tab extending across the air gap defined between the free end of the upper yoke member and the opposite end of the core.  Extended from the upper end of the tab is an actuator arm which is received in said slot and on which overlies a spring blade carrying at its free end a movable contact.  Upon hinging movement of the armature in one direction in response to the coil being energized, the actuator arm presses upwardly the spring blade to engage or disengage the movable contact from a cooperating fixed contact.  Conversely, when the coil is deenergized the armature is driven to hinge in the opposite direction by the biasing force from the spring blade to disengage or engage the movable contact with the fixed contact.  During this hinging movement of the armature, the actuator arm of the armature is kept substantially within said slot in the upper yoke member, requiring no additional spacing above the yoke for the the movement of the armature. That is, the thickness of the actuator arm can be substantially received within the upper yoke member so as to reduce the total thickness or height, presenting a very compact arrangement with respect to the height of the relay.

Abstract: CHEESE STARTER MEDIA AND METHOD OF MAKING SAME            Abstract of the Disclosure Low cost, readily dispersible, phage-resistant cheese starter media are described which include milk-derived nutrients (e.g., nonfat milk and whey) along with a minor proportion of prefer-ably free or unbound lecithin.  The media also may advantageously include sodium tetraphosphate which assists in the dispersion of whey solids.  The media of the invention can be used at significant-ly lower levels as compared with nonfat dry milk solids (e.g. 7 percent versus 12 percent), while nevertheless   obtaining  essentially  equivalent results in terms of culture growth and final culture properties.  A method of producing the media is also disclosed, involving liquid pre-blending of phosphates and lecithin, followed by addition thereof to milk-derived nutrients and reaction of the phosphates to tie up free calcium ion.  The final step involves drying of the mix-ture to yield a substantially homogeneous, recon-stitutable powder.  In other cases the phosphate-lecithin preblend can be dried for later addition to  milk-derived  nutrients  to  produce  a  final starter medium.

Abstract: Abstract of the Disclosure A double lumen catheter made up of an elongated integral flexible plastic thin-walled tubular body extending from a proximal end part, through an intermediate part, to a distal end part, terminating in a tip.  The intermediate part has an outer wall and an internal septum wall contain-ing juxtaposed arterial and venous lumens.  The terminal end of each lumen in the proximal part is adapted for connec-tion to an access tube to hemodialysis apparatus.  At the junction of the intermediate part and the distal part, the arterial lumen is terminated and the venous lumen continued at least part way to the tip of the distal part.  The out-side surface of the outer walls are continuous and smooth to offer minimum resistance to insertion into the body of a patient.  The walls are also relatively thin to provide for lumens of relatively large cross-section compared to the total cross-section of the catheter body.  Removable obturators are inserted in the lumens to prevent the catheter from buckling.  The inner surface of the outer walls and the surfaces of the septum wall are continuous and smooth and any change of direction in the lumen wall is in a gradual curve to accommodate negotiation by a flexible obturator.  Alternatively, the catheter may be made from tubing sufficiently resistant in itself to buckling for the catheter to be inserted without the use of obturators.  One such form of tubing is made of alter-nating hard and soft plastic rings welded together.          Another form employs wire reinforcing within the walls.          Welding and molding methods for making the catheters are disclosed.
