Abstract: Abstract An improved fastener indicates when a predetermined preload has been applied to the fastener.  The fastener includes a body section which is connected with a thread convolution.  A load transmitting and indicating section is connected with the body section.  The load transmitting and indicating section includes a bearing section having a flat annular bottom surface and an undulating annular spring section which circumscribes the bearing section. The spring section has a bottom surface with crest and trough portions.  The crest portions extend tangentially to the plane of the bottom surface of the bearing section.  The trough portions are resiliently deflectable toward the body section to flatten the undulations in the spring section upon application of the predetermined preload to the fastener.  The spring section is resiliently returnable toward an initial configuration to increase the amplitude of the undulations in the spring section to provide a visual indication that the connection between the fastener and a member is loosening.

Abstract: ABSTRACT OF THE DISCLOSURE A specific type of protein, which has been designated B-protein (Bucovaz-protein), is present in most serum of individuals with cancer.  The B-protein interacts with a low molecular weight protein component, which is released by the coenzyme A-synthesizing protein complex (CoA-SPC) of Bakers' yeast during the course of CoA synthesis.  This low molecular weight protein, for purposes of identification, is referred to as binding protein.  The binding protein has a molecular weight of 10,000 to 15,000.  Interaction of radioactively labeled binding protein of CoA-SPC with the B-protein of serum provides a marker for the detection of cancer.  Of 3005 serums assayed, which included 908 patients diagnosed as having cancer, the B-protein assay agreed with the clinical diagnosis in more than 89% of the cases.

Abstract: ABSTRACT OF THE DISCLOSURE         A building construction system that permits the erection of a modular-skeleton structure type building in a very short time utilizing relatively unskilled labour.  The construction system utilizes a skeleton-type structure consisting of vertical metal profile posts which extend from the foundation to the horizontal roof girders in a single unit of uniform cross-section.  The roof girders are attached by means of slotted tension bolts.  The one-piece vertical profile posts have a cross-section which is essentially the combination of a T-section and a U-section.  In the lower part of the building, basement wall elements extend into the vertical profile posts with their angled legs on the inside of the building.  In this position, they are secured by a bracing tube.

Abstract: A b s t r a c t Coating compound for silica bricks The porosity of silica bricks ranges between about 15 and 25%.   Only less than 1% of the pores are closed because of the low glass content.   Consequently, silica bricks do not have a compact fired skin.   The object of the invention  is to enable the surface of silica bricks intended more particularly for the construction of the walls of pitch coke ovens to be protected against the penetration of liquid and gaseous substances and prevent graphite incrustations as far as possible, by the use of an extremely simple and relatively inexpensive method.     To this end, according to the invention, a suspension of water-glass powder and glass powder together with a stabilizer if required, e.g. hydroxy ethyl cellulose, in a concentrated water solution, is applied to the surface of a fired or unfired silica brick, dried and then baked in.   This gives a substantially sealed and smooth surface.

Abstract: ABSTRACT OF THE DISCLOSURE        In a valve wherein a flexible tube is stretched around a circular barrier between inlet and outlet slots and is conditioned to enable flow in an annular path around the barrier when upstream pressure overcomes pressure in a control jacket around the tube, the improvement comprising a second flow path directly through the barrier, which is normally closed off by a poppet valve engagable with a seat around the passage. A spring augmented by a control pressure biases the valve toward closed position and is preferably set so that, only after capacity of the flexible tube is reached or approached, does the poppet valve open to answer the need for high pressure demand downstream or for relief of a high pressure surge upstream.

Abstract: METHOD AND APPARATUS FOR ANALYZING WELL FLUIDS BY PHOTON IRRADIATION             Abstract of the Disclosure In a method for analyzing a mixture containing water and a hydrocarbon, notably for determining the composition of the fluids produced in a petroleum well, the flux resulting from the interaction of incident photons with the mixture is measured on two distinct energy levels, at least one of these levels corresponding to a significant rate of absorption by a photoelectric effect.   Advantageously, use is made of an X-ray generator (80) on a tool mandrel (60) on which are mounted two radiation receivers (82) and (84) placed at different respective distances from this generator (89) along the mandrel.  The measurement makes it possible to determine a parameter characteristic of the photoelectric absorption capacity of the medium and its density, notably in order to deduce the composition of a ternary mixture, for example a mixture of petroleum and of water of unknown salinity.

Abstract: ABSTRACT OF THE DISCLOSURE     To dry wet fabrics, a hot drying gas is introduced into a drying chamber containing the fabrics.  The drying chamber is maintained at a suffi-ciently high pressure greater than atmospheric pressure so that a portion of the gas in the drying chamber can be discharged directly to the atmosphere. The remainder of the gas in the drying chamber is withdrawn, and at least a portion of the withdrawn gas is used to produce the hot drying gas introduced into the drying chamber.  This is effected by increasing the pressure of the withdrawn gas, heating the  withdrawn gas, and combining it with a dilution gas.  The amount of the dilution gas which is combined with the withdrawn gas comprises from about 5 to about 20% by volume of the hot drying gas introduced into the drying chamber.  Before the withdrawn gas is heated, preferably it is filtered by a lint screen for removal of lint and other contaminants.  Novel lint screens capable of self-cleaning during a cooling mode of operation are described.

Abstract: ABSTRACT OF THE DISCLOSURE       This invention is concerned with a continuous process for improving the manufacture of alkanols containing 1 to 2 carbon atoms, especially ethylene glycol and methanol, or carboxylate derivatives thereof from the reaction of hydrogen and carbon monoxide, by a continuous homogeneous catalytic process using as the catalyst a solubilized ruthenium carbonyl compound and a rhodium carbonyl compound by maintaining the concentration of ethylene glycol or carboxylate derivatives thereof in the reaction medium at less than about 20 weight percent and the combined concentration of methanol, ethanol and ethylene glycol or carboxylate derivatives thereof at less than about 50 weight percent.  The continuous process is operated in such a manner that products are removed from the reactor so as to maintain the total concentration in the reaction medium at the desired concentrations such that the net effect is that the overall efficiency of the reaction to the production of ethylene glycol is more favorable.
