Abstract: FRAMELESS METAL BUILDING  AND BUILDING COMPONENTS                    Abstract of the Disclosure .              A series of rectangular sheet metal roof and wall panels each includes inner and outer corrugated skin portions which are connected by web members or portions which may also be corrugated.          A fabricated sheet metal ridge beam rigidly connects the inner skin portions of the roof panels on opposite si des of the ridge to transmit tension forces, and connects the outer skin portions of the roof panels for transmitting compression forces. Inclined inner eave attachment plates or panels rigidly connect the skin portions of the roof and wall panels, and other eave attachment members rigidly connect the roof panels and wall panels to form a building structure which has substan-tial total strength and may be easily and quickly erected without the use of a crane, Each of the roof and wall panels is prepunched and may be formed from a single metal sheet which has a single major corrugation or a Z-shaped lateral configuration. Longitudinally spaced sheet metal spacers connect the outer skin portions and web portions of assembled panels, and longitudinally spaced and laterally extending elongated stiffeners or tie members rigidly connect the inner skin portions and spacers of the assembled panels.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to the induction of interferon production in the cells of living organisms, in-cluding human beings.  According to the invention, nucleic acid complexes, such as the polyriboinosinate and polycytidylate complex (rIn?rCn), are modified to yield unpaired bases (uracil or guanine) along the polycytidylate strand which render the complexes more readily hydrolyzable by nucleases present in living cells.  The modified complexes retain their ability to stimulate interferon release by the cells but are rendered more vulnerable to destruction within the cells, the modified complexes being significantly less toxic than the original complexes.  In addition, polyinosinate strand now has been prepared to contain 5-16% 2'-O-methyl inosinate residues, designated as (rI5-20,2'-MeI)n.  The new complex (rI5-20,2'-MeI)n? rCn, exhibits 100-fold more activity than rIn?rCn as an interferon inducer in human cells.         This patent application is a divisional of Canadian patent application Serial No. 212,624 filed by Applicants on October 30, 1974 for "Induction of Interferon Production by Modified Nucleic Acid Complexes".

Abstract: Abstract of the Disclosure Boron trichloride is prepared by free-radical chlorination of liquid borate ester, e.g., trimethyl borate, at temperatures of between about 20°C. and 100°C.  Color bodies which form and accumulate in the liquid reaction mixture are removed by extracting a purge fraction of the reaction mixture from the reactor, distilling such liquid reaction mixture, and recycling distillate obtained from the distillation to the reactor.          The volume of the purge fraction can vary between about 4 and about 20 volume percent of the reaction mixture per hour.  Borate ester can be added to the distillate before introducing it into the reactor.

Abstract: ABSTRACT OF THE DISCLOSURE         The thermodynamic efficiency of a tar sands condition-ing drum is improved by continuously and simultaneously dis-charging steam from all the nozzles of an array of a few relatively large nozzles distributed circumferentially around the inner drum periphery rather than selectively sparging the steam only from those nozzles beneath the tar sands pulp sur-face.  As a result, the drum shell and components above the pulp are heated and thus heat the pulp by radiation and, after entering the pulp, by convection as well as by sparging.  Hot water droplets formed continuously in the steam cloud rain onto the pulp surface to provide another highly important heat transfer mechanism.  Coincidentally, mechanical reliability and economics are achieved by eliminating the sparge valve and multiplicity of smaller nozzles which characterize the prior art tar sands conditioning drums.

Abstract: TAMPER-RESISTANT TELEVISION SIGNAL SCRAMBLING          Abstract of the Disclosure A method and apparatus for blocking the reception of a subscription television program while substituting a replacement program at a blocked receiver, provide security against detuning an unauthorized receiver to receive the subscription program.  A security carrier signal is provided in a subscription television signal at the frequency of the audio carrier of the lower adjacent channel and is alternately amplitude modulated with bursts from first and second interference frequencies at a third or keying frequency.  The television signal also includes an interfering scanner signal intermediate the audio and video carriers in the channel and the interfering is modulated with a substitute television program.  When a receiver is properly tuned to the channel, the security carrier has no effect on reception and either the subscription or substitute program is received, depending on whether the receiver is authorized or not. Should an attempt be made to receive the subscription program in an unauthorized receiver by detuning the receiver, the security carrier interferes with or blocks video reception in the detuned receiver and the modulation as that carrier produces a moving visual pattern which is extremely annoying to a viewer.

Abstract: ABSTRACT OF THE DISCLOSURE   A novel method and apparatus are provided for mixing and dissolving solid and liquid substances.  The method includes the steps of first keeping both the solid and liquid substances to be mixed continuously in a constant circulation inside an in-line mixing zone surrounded axially by the mixing/ reactor zone using an external source of mixing energy to maintain a mix-ture or solution.  The next step involves continuously internally recircu-lating a portion of the mixture or solution along with an additional por-tion of the mixture or solution from an external source in a separate concentric circulating zone within the mixing/reactor zone.  The next step in-volves continuously withdrawing a portion of the mixture or a portion of the solution from the concentric zone through  an annular outlet connection zone leading to the mixing/reactor zone and thence through an annular inlet connection zone leading to the concentric zone.  The next step involves continuously discharging a solution from the mixing/reactor zone through a separate annular discharge zone and through outlet zones to a level-controlling dis-charge zone. The final step includes continuously and controllably supply-ing an amount of both the solid and the liquid substances to the mixing/reactor zone, the supplied amount being equal to the discharged solution withdrawn through the discharge zone.  The apparatus for performing the method com-prises a specially configured loop-type reactor having a special mixing and dissolving chamber with internal recirculating means and separate with-drawal means to external recycling means.  By this method and apparatus, a solution is obtained in a continuous flow.

Abstract: ABSTRACT     A safety circuit for a lifting device extensible boom is presented wherein the boom angle of elevation and boom length are each converted into a parallel coded word.  The two coded words, one representing boom angle and the other boom length, are processed in a digital logic network which provides inhi-bit functions that prevent boom extension or boom lowering when either of the two boom actions will place the boom in a position which will damage the boom or topple the machine.  A plurality of switches are associated with the boom to generate and apply the boom length code word to a monitoring circuit, which responds thereto to provide a switch malfunction signal when one of the switches is defective, whereby boom extension or lowering are inhibited.
