Abstract: STABLE LEAD DIOXIDE ANODE AND    METHOD FOR PRODUCTION                          Abstract An improved insoluble anode for electrowinning is described which comprises a graphite substrate covered by a tight fitting sheet of a nonconductive electrolytically inert mesh material over which covered substrate is electrodeposited a layer of lead dioxide.  The anode is formed by covering the graphite substrate with a sheet of the inert mesh material and thereafter electrodepositing lead dioxide thereon until a smooth layer of lead dioxide completely covers the mesh material.          The anodes are electrolytically stable and are not susceptible to cracking.

Abstract: GAME APPARATUS     Abstract of the Disclosure In the game disclosed herein, participants move their tokens, each representing a detective, over an indicia-carrying game board in pursuit of an imaginary thief whose location is not apparent on the board.  The indicia on the board defines a multiplicity of locations of several types and possible paths of movement between locations in accordance with certain rules of the game.  A value representing the location of the imaginary thief is held in a memory or storage register within a digital computing apparatus.  The digital computing apparatus also inclu-des a fixed table of information representing the various playing field locations, together with data representing the character of each location.  The value representing the location of the thief is periodically changed, upon player initiation, in a manner determined by a random number generator but in a conformance with predetermined rules of movement.  The digital computing apparatus also drives sound generating means to produce one of a plurality of characteristic sounds following each of the thief's moves.          Each characteristic sound is associated with a particular type of location on the playing field so that the sounds constitute clues as to the thief's movement and location.  The digital computing apparatus includes also a player operable means for initiating a capture and for designating a playing field location at which the capture is to take place.  The processor determines whether the player has properly located the thief and generates corresponding audible sounds indicating success or failure.

Abstract: ABSTRACT           A hinge link connecting a cover to an office copier machine is completely enclosed by the cover when the cover is swung down in a closed position on the copier machine.  One edge of the hinge link is connected to the top of the copier machine by a first pivotal joint or connection and an opposed edge of the hinge link is connected to the cover by a second pivotal joint or connection.  The two pivotal joints or connections permit the cover to be swung open around the first pivotal joint and enable the cover to be disposed substantially parallel to the copier top to accommodate articles of varying thickness placed between a platen on the top of the copier and the cover.  The hinge link can be planar or angular.  In the angular construction, the short leg of the angle is substantially the height of the cover with the other leg having a length greater than the short leg to permit the hinge link to be totally enclosed within the chamber of the cover and to enable the cover to be disposed spaced from the copier top.

Abstract: ABSTRACT OF THE DISCLOSURE         In a yarn tube having a yarn-supporting surface, a yarn-receiving pickup groove formed in the surface and extending circumferentially at least partially around the tube.  The groove, specifically configured to accommodate both right hand and left hand yarn pickup, has a constant varying width along the length thereof, and either two widest sections or a common widest section capable of allowing "dropping in" and orientation of the yarn from both the right and left.  Constantly narrowing sections extend outward from the widest section or sections to a common narrowest section or point to insure proper snagging of the yarn, initially received within the wide section or sections, regardless of the direction of rotation of the tube or the thickness of the yarn.  The entire groove is of constant depth with the constant varying width insuring an accommodation and proper gripping of the yarn over a wide denier range.

Abstract: ABSTRACT OF THE DISCLOSURE        An extracorporeal blood circulation system including a line for withdrawing the venous blood from the patient, an artificial lung provided on the line, a reservoir for the blood withdrawn, a blood supply line for sending out the blood from the reservoir to the artery of the patient, and a blood supply pump provided on the blood supply line and serving as an artificial heart.  The amount of blood to be supplied is automatically controlled to maintain the arterial pressure of the patient in a suitable required range.          The blood supply pump is stopped when the arterial pressure of the patient measured is above a predetermined upper limit value, while the pump is driven when the arterial pressure has lowered to a level below a lower limit value.  The amount of blood to be withdrawn is also controlled automatically to keep the central venous pressure of the patient approximately constant. The blood withdrawing line has a blood withdrawing pump.          The reservoir is connected to the inlet side of this pump by a shunt line having a valve which is usually opened.  The valve is closed when the central venous pressure exceeds a predetermined upper limit level.  A vertical overflow tube detects the central venous pressure exceeding the upper limit level.

Abstract: ABSTRACT OF THE DISCLOSURE          In the exemplary embodiments of the invention disclosed, the decay of the thermal neutron concentration in an earth formation following irradiation thereof with a burst of fast neutrons is measured by detecting indications of the thermal neutron concentration during a sequence of contiguous, discrete time gates between neutron bursts.  The time gate sequence begins following a discrete time delay after the commencement of the preceding neutron burst and extends over the entire, or substan-tially the entire, remainder of the interval between neutron bursts.  The time gates are grouped into a number of gate groups, e.g. four, each of which includes a number, e.g. four, of discrete time gates.  Both the time gates within each group and the groups themselves are contiguous in time.  The durations of the individual discrete time gates within the separate groups are equal, but the duration of the time gates progressively increases from group to group in the sequence.  The duration of the neutron bursts, the duration of time delay between the end of the bursts and the beginning of the gating sequence, and the durations of the individ-ual time gates may all be adjusted by a common, selected one of a finite number, e.g. four, of scale factor values.  Selection of the particular scale factor value used in the measurement of a given formation is made in a manner to optimize the statistical precision of the measurement of thermal neutron decay constants, e.g. ? and .SIGMA., of the formation.
