Abstract: ABSTRACT OF THE DISCLOSURE    Radioassay for vitamin B-12 using the unknown quantity of non-radioactive vitamin B-12 released from serum mixed with the radioactivity of a known quantity of radioactive vitamin B-12 tracer.  A solution of intrinsic factor having a binding capacity less than the quantity of serum vitamin B-12 and radioactive vitamin B-12 is used to bind a portion of the vitamin B-12 mixture.  The vitamin B-12 not bound to intrinsic factor is removed by addition of a bentonite-containing tablet.  The quantity of radioactive vitamin B-12 bound to intrinsic factor is compared with standard values and the unknown serum vitamin B-12 obtained.    In the steps of the procedure the acid assay medium is pre-combined with the radioactive tracer so that the radioactive vitamin B-12 tracer receives the same treatment as serum vitamin B-12.  Certain of the other reagent solutions are pre-combined and the concentration of the components adjusted so that the volume used of each of these other reagent solutions is the same in different assay steps.  Thus, fewer pipetting steps are necessary.

Abstract: ABSTRACT OF THE DISCLOSURE             A track mounting device for printed circuit board includes an elongated channel member of generally U-shaped cross-section and including intermediate opposed resilient finger means for resiliently gripping the circuit board, as well as opposed intermediate thickened portions for reinforcing the upstanding parallel side walls of the track device.          Furthermore, the track mounting device is provided with opposed protrusions disposed at the opposite ends of the side walls and projecting into the space between said side walls.  The spacing between the opposed protrusions is less than the spacing between the opposed thickened portions, but greater than the spacing between the opposed resilient fingers.  The end protrusions limit the vibration of the printed circuit board at its extremities where vibrations are the greatest, and also prevent the inadvertant insertion into the track of oversized (thickness) printed circuit cards.  The protrusions also aid in reinforcing the upstanding side walls of the track mounting device.

Abstract: Abstract of the Disclosure An apparatus for retreading tires with a precured and premolded tire tread material comprises a multi-part rigid shell for holding a tire and a precured tread assembly, the shell defining a sealed chamber around the tread of the assembly.   The shell has a base, with a flat circular portion formed thereon and adapted to support a tire and precured tread assembly, an annular ring member extending upwardly from the circular portion of said base, and a cover having a flat circular portion mounted on the annular ring member and secured to said annular ring and said base by upwardly extending securing means.   The base, ring, and cover define the sealed chamber around the tread portion of the assembly.          A thin flexible envelope covers the assembly from sidewall to sidewall around its outer perimeter.   Sealing means provides a seal between the flexible envelope and the base and cover means at each of the sidewalls of the assembly.   The sealing means cooperates with the base and cover and the exterior surface of the envelope to provide a fluid tight seal for the chamber.   Fluid inlet and exhaust means are provided for pres-surizing and heating the fluid within the annular chamber.   An inflatable means is mounted for inflation within the assembly to a pressure greater than the pressure in the annular chamber and laterally distends the sidewalls of the assembly to urge them into contact with the sealing means.   Means mounted between the assembly and the envelope evacuate air trapped between the surface of the tire and precured tread assembly and the thin flexible envelope.

Abstract: Abstract A cycloalkane is oxidized in the liquid phase at elevated temperature and pressure to the corresponding cycloalkanone and/or cycloalkanol by means of a molecular oxygen-containing gas and in the presence of a dissolved metal serving as a catalyst but in the absence of a boric acid derivative.  The unreacted cycloalkane is separated from the reaction mixture and recycled to the oxidation step. Prior to recycling unreacted cycloalkane, water is evaporated from cycloalkane to be oxidized as a azeotrope with the cycloalkane.  It has been found that evaporation of the water from cyclolakane to be oxidized by this process reduces fouling of the oxidation reactor vessels, and reduces the occurence of oxygen breakthrough.

Abstract: TREATMENT OF ORGANIC WASTE          LeRoy F. Grantham ABSTRACT      An organic waste containing at least one element selected from the group consisting of strontium, cesium, iodine and ruthenium is treated to achieve a substantial reduction in the volume of the waste and provide for fixation of the selected element in an inert salt.  The method of treatment comprises introducing the organic waste and a source of oxygen into a molten salt bath maintained at an elevated temperature to produce solid and gaseous reaction products.  The gaseous reaction products comprise carbon dioxide and water vapor, and the solid reaction products comprise the inorganic ash constituents of the organic waste and the selected element which is retained in the molten salt.  The molten salt bath comprises one or more alkali metal carbonates, and may optionally include from 1 to about 25 wt.% of an alkali metal sulfate.

This safety latch includes a latch housing, a slidable bolt having a wedge shape outer end portion selectively retractable in the latch housing, a cam rotatably engaging the bolt and operatively retracting the latter, a stem extending endwise into the latch housing, axially pushable inward, and operatively rotating the cam for retraction of the bolt by the cam upon rotation of the stem while the latter is held inwardly pushed.

Abstract: ABSTRACT    In a generator of musical notes for use as an electronic organ or other instrument, particularly of keyboard type, a computer is programmed to provide control and data signals to external hardware in response to the selection of stops and keys.          In response to each change of stop a range of characteristic harmonic structures is synthesised digitally to provide single-cycle reference waveforms for storage for so long as that stop remains in use.  In response to the selection of a key in that stop an appropriate reference waveform is sampled, or interpolative sampling is performed between two waveforms, so that an harmonic structure is produced by sampling which is precisely related to the position of the key in the register.  The pitch of the note to be reproduced from the digital samples is determined by the rate of sampling which can be finely resolved.  Samples are read at a fixed clock rate, but the number of clock intervals required to step through the single-cycle reference waveform is caused to be inversely proportional to the required pitch.   Many independent notes can be produced simultaneously for audio-reproduction following digital-to-analogue conversion of the sample values.
