Abstract: CHARACTER SET EXPANSION                 Abstract of the Disclosure A method of, and system for, increasing the number of characters available to be printed with a single print element.  If a printer is printing from storage and the character being presented to the printer does not match the print element in use, a determination is made as to whether the character is in fact available on the element.  If so, the character is caused to be printed.  If not, a determination is made as to whether the presented character can be constructed from characters existing on the print element.  If so, construction is caused to occur to avoid a print element change.  If, however, the presented character does not exist on the print element and cannot be constructed from characters that do exist on the print element, a requirement for a print element change is signalled.          Following a change, printing will continue with the new print element as long as characters are available, or can be constructed from available characters.   As such, throughput is improved and required operator attention is diminished.

Abstract: Abstract of the Disclosure Symbiotic microorganisms such as nitrogen fixing bacteria and phosphorus-providing fungi are isolated from nodules and mycorrhiza on the roots of host plants by sterilizing the surface and subsurface areas of root tissue with an aqueous solution of a fixative containing osmium tetraoxide.  The osmium tetraoxide is highly soluble in water, and volatil-izes at room temperature to form a vapor which penetrates subsurface air pockets in root tissues to kill contaminating microorganisms.  The osmium tetraoxide also provides a visual indicator of its progress through plant tissue by a progressive darkening of such tissue from the surface of root samples toward their centers.  In this manner, the sterilization can be halted before the centrally located causitive bacteria is destroyed.

Abstract: TOOL MOUNT ASSEMBLY METHOD Abstract of the Disclosure A torsion bar disk gang mounting assembly includes a shaft pivotally suspended from a disk frame.  A rectangular tube re-ceives a portion of the shaft.  A pair of disk gang support arms are pivotally coupled to the shaft and extend generally rear-wardly therefrom.  The arms are fixed to opposite ends of the tube and support a disk gang at their distal ends.  A torsion bar is resiliently coupled between the tube and the shaft to bias the disk gang downwardly.  A method of making such a disk gang mount-ing assembly includes the steps of assembling the shaft, tube and torsion bar, then fixing the arms to ends of the tube.  The shaft is then pivoted with respect to the tube and arms to es-tablish a predetermined preload in the torsion bar.  A stop arm is then fixed to the shaft in engagement with an abutment on one of the arms to maintain the preload in the torsion bar and to limit downward movement of the disk gang.  Coupling holes are then drilled in the ends of the shaft with a certain orientation with respect to the arms so that consecutive shafts may be coupled together with coupling collars.

Abstract: The anodes for the electrolytic production of zinc from acid aqueous solutions of sulphate comprise a skin portion formed by conventional anode metal, lead containing from 0.25 to 1.0% silver, and a stiffening reinforcing member of titanium or zirconium. The reduction in thickness of the anodes, which is made possible by the provision of the reinforcing member, results in a substantial saving in the amount of silver-bearing lead which is immobilized, and a substantial reduction in the unit weight of the anodes. The resistance of the lead to anodic corrosion in a sulphuric acid medium is maintained and the resistance to corrosion by passivation of the reinforcing member permits the reinforcing member to be accidentally exposed, without disadvantage. To produce the anodes, the reinforcing members are clad with lead at a temperature of more than 100 DEG  by rolling sheets of lead, by casting in a mould or by spraying on molten lead.

Abstract: ABSTRACT    An extensometer, for use in determining extensions or creep in studs or bolts for example, has a first tubular member in which slides a tube assembly carrying a second collet-like member.  First and second abutment formations on said first and second members, respectively, engage internal shoulders in a stud.  Upper and lower brackets which are restrained against separation, by a spring, beyond a datum position, are fixed relatively to said first and second members, respectively.  A dial gauge (0.01 mm divisions), which co-operates with a datum block on said lower bracket, is mounted on said upper bracket.      With the extensometer in position, the spring is stressed by relatively moving said first and second members to position said second abutment formation below the lower shoulder in the stud.  A plunger member is moved relative to said second member to expand the spring fingers thereof outwardly.  The spring is allowed to relax and pull said second abutment formation into contact with the shoulder.  The dial gauge can be then read.      In a modification, said first member can be a collet-like member also.
