Abstract: Figure Displaying Device Abstract of the Disclosure A figure displaying device operates to display a plurality of fundamental figures, each defined by a preset number of vectors, on a device of the raster scanning type.  The figure displaying device stores the start and end point coordinates of the vectors of the respective fundamental figures and the gradient vectors of the data of the respective fundamental figures and determines whether the respective vectors are located on a horizontal scanning line or not for each fundamental figure prior to the scanning operation of the horizontal scanning line. If the vectors are located on the horizontal scanning line the gradient data corresponding to the vectors on the aforementioned horizontal scanning line are read out and added to the start point coordinates whereby to renew the start point coordinates.  A line memory is provided having a capacity corresponding to the number of picture elements in one horizontal scanning line so that preset data can be stored therein at the address corresponding to the added results.  A control circuit consecutively reads the data out of the address in the line memory, which corresponds to the position of the horizontal scanning line being scanned, whereby to effect the display in accordance with the read results.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a composition for the improvement of the adhesion and adhesion retention between conventional rubber skim stock compositions, utilized in the manufacture of tires, conveyor belts, hoses and the like, and metallic reinforcement cords such as brassed steel.  The invention composition is prepared by incorporating an inorganic salt of cobalt or nickel and a rosin-derived resin into the rubber stock prior to contacting the metallic reinforce-ment.  Tests conducted with brass-plated and zinc-plated steel cords showed improved metal adhesion and metal adhesion retention with use of the rubber skim stock of this inven-tion when compared to existing formulations.

Abstract: PROCESSING OF SEA URCHINS        ABSTRACT of DISCLOSURE         A tool for cracking the shells of sea urchins, comprising a blade formed with central recess which enables the blade to penetrate the shell in the region of the mouth thereof without causing significant damage to the internal organs or roe of the sea urchin, and means for restraining the shell and for moving said blade laterally with respect to said restraining means to thereby open the shell. In its simplest form, the blade is formed at one end of one handle of a hand tool while the restraining means is formed at one end of a handle to which the first mentioned handle is pivotted to achieve said lateral movement of said blade.  In a more sophisticated embodiment, the blade is mounted for vertical movement by means of a pneumatic cylinder and is arranged for lateral movement relative to the restraining means by means of a further pneumatic cylinder which operates when the blade is in the shell penetrating position.        Also disclosed is a system for processing sea urchins in which the shell is opened at sea by means of a shell cracking device while other sea urchins are being harvested, the roe in said shell being removed and stored in a suitable solution for transport back to shore where-upon it is further processed for final transport to its intended market.  This processing system enables the processing time and labour content to be substantially reduced and for the roe so harvested to be delivered to the intended market much faster than is presently possible.

Abstract: HIGH-SPEED SMOKELESS COKE OVEN BATTERY         AND METHOD OF OPERATION                 ABSTRACT OF THE DISCLOSURE         A plurality of sole flue-heated, nonrecovery coke ovens constructed in side-by-side relation in a battery have their chimney uptake outlets connected to a common combustion tunnel extending longitudinally of and above the battery and connected to stacks at spaced intervals along its length.  Each oven has a bypass  flue directly connecting the top of its coking chamber to the combustion tunnel, and a normally closed valve in each bypass  is operable to selectively connect the coking chamber to the tunnel to permit charging gases to be drawn from the chambers to be burned in the tunnel and stack.  The bypass  valve is closed during coking so that the partially burned gases from the crown of the coking chambers are led through downcomers in the oven walls to the sole flues where a controlled amount of combustion air can be admitted to promote the continued burning process and provide maximum heat in the sole flues.  The gases then pass through the chimney uptakes to the tunnel where additional combustion air can be admitted to assure complete combustion in the tunnel and stack before being discharged to the atmosphere.  Combustion air admitted into the sole flues can be preheated  in pipes extending through the base slab beneath the sole flues where waste heat is extracted to protect the foundation of the ovens while increasing the temperature in the sole flues.
