Patent CA-1062002-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE     A process and apparatus for maintaining the uniform moisture content in a continuously conveyed batch of porous materials is described. The porous material is continuously fed through a treatment tank, wherein it is contacted with a liquid to be absorbed therein.  The moisture content of the material is continuously monitored as a direct function of the com-bined weight of the material and the treatment tank to generate error or correction signals, as compared to the uniform weight (moisture content) desired.  The control or error signals are utilized to vary the dwell times (up or down) of the porous material in the treatment tank.  By varying the dwell times the porous material is contacted by the treating liquid for either larger or shorter periods until the weight of the tank and material therein returns to the uniform weight desired.  Thus, the moisture content of the porous material is continuously adjusted to substantially maintain a uniform standard.

Abstract: Abstract of the Disclosure Organic solid wastes represented by the general chemical formula CXHYOZ are reacted with steam at elevated temperatures to produce H2 and CO2.  The overall process is represented by the re-action CXHYOZ + 2(X-Z/2)H2O ? XCO2 +                           (1) [(Y/2) + 2(2X-Z/2)] H2 .            Reaction (1) is endothermic and requires heat.  This heat is sup-plied by a tower top solar furnace; alternatively, some of the solid wastes can be burned to supply heat for the reaction.  The hydrogen produced by reaction (1) can be used as a fuel or a chem-ical feedstock.  Alternatively, methanol can be produced by the commercial process CO2 + 3H2 ?  CH3OH + H2O   .                    (2) Since reaction (1) is endothermic, the system represents a method for storing heat energy from an external source in a chemical fuel produced from solid wastes.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for the manufacture of circular workpieces from hypereutectoid steel, which forms, after quenching or harde-ning, a low carbon martensite with a dislocation structure.         This process consists in the preparation of ring shaped semipro-ducts by centrifugal casting, cleaning of these semiproducts from layers of slag and other impurities, cooling these rings from the casting temperature to a temperature at the maximum 100° C below the eutectoid temperature change of the structure of this steel, again heated to a temperature at the maximum 100° C above the temperature of eutectoid change.  After obtaining a structure of spheroidized perlite, the temperature is raised to a value at the maximum 1150° C, the semiproduct is formed for instance by rol-ling, thereafter quenched and tempered.

Abstract: ABSTRACT OF THE DISCLOSURE        A process for improving the properties, particularly the dyeing properties, of cellulose fibers. The process comprises impregnating cellulose fiber with an aromatic acyl halide and thereafter immersing the impregnated fiber into an aqueous solution containing more than about 10% by weight of an alkali hydroxide to acylate the cellulose fiber on the surface portion thereof. In another embodiment of the invention, a continuous process for improving the properties of cellulose fiber yarn of fabric is provided. According to the continuous process, uniform acylation is achieved  by maintaining the yarn or fabric in a stretched state during impregnation with the aromatic acyl halide and during the initial stages of immersion in the aqueous alkali hydroxide. The acylated cellulose fiber produced according to the invention may be dyed with good color fastness with disperse dyes and still retain the soft tactility characteristic of the fiber.

Abstract: ABSTRACT OF THE DISCLOSURE             A testable protective system for an operating system is provided with redundant trip components serially connected to redundant lock-out components.  The trip com-ponents are signaled by fault sensors which monitor cri-tical conditions of the operating system.  These trip components produce an output indicative of such conditions, which output is fed to certain actuated devices which may either correct the condition or shut down the operating system until the cause of the problem can be determined and the necessary repairs made.  When it is desired to test one of these trip components, the operator activates the corresponding lock-out component and performs the necessary test.  The activation of this lock-out component has an effect of making the protective system output signal (the output to the actuated devices to correct the fault or shut the system down) independent of the output of that trip component when it is being tested.  Should an operator mistakenly activate both lock-out components at once, the protective system output signal is a function only of the fault sensor input to a first trip component and a driving signal to the protective system.  Thus, even if both lock-out components are activated at once, a fault signal to the first trip component will effect a fault output signal from the protective system to the actuated devices.

The drum comprises a circumferential array of drum-forming segments which are supported for radial dis-placement to and from contracted and expanded dispositions, and apparatus for displacing the segments radially between the contracted and expanded dispositions.  Each of the segments has the same axial extent and terminates at each end in a respective flange projecting radially in-wardly.  Each of the flanges has a respective recess exposed radially outwardly, corresponding ones of the recesses which are at the same segment end defining co-operatively with one another at each such segment end a radially outwardly exposed annular bead-seat.  The segments, when in a fully contracted disposition, present a substantially cylindrical outer carcass-ply support-surface having a diameter which is less than the inner diameter of any annular metallic bead-core to be thereby operated upon.

Abstract: ABSTRACT      An apparatus comprises an explosion made in the form of a tube closed at one end which accomiodates at least one spark plug.  The explosion chamber communicates with a chamber for preparation of an explosive mixture and with a batcher metering pulverulent coating material, via a mixing chamber of the batcher communicating with a hopper, via a passage.  The passage incorporates a device for controlling the cross-sectional area thereof and is provided with a jet nozzle for positively feeding the coating material to the explosion chamber.  A partition wall of a gas-permeable material is mounted within the hopper in equally spaced relation to the walls thereof to define an annular space communicating with a compressed gas source preventing self-compaction of the powder.  A non-return valve is mounted in the batcher passage, in the portion thereof connected to the hopper which shuts-up the passage in case of back impact from the explosion chamber.      This apparatus provides for more reliable cyclic batching of pulverulent coating material fed to the explosion chamber and is reliably protected against break-through of gas in case of back impact from the explosion chamber as compared with conventional apparatus of the same type.  This considerably improves quality of coatings, especially when finely commented pulverulent coating materials based on refractory compounds are used.

Abstract: VARIABLE ADJUSTER FOR DISC BRAKE  ABSTRACT OF THE DISCLOSURE A disc brake provides an adjustment mechanism to dispose a pair of friction elements In close proximity to a rotor by limiting the amount of retraction of the friction elements from the rotor.  The adjustment mechanism has more than one rate of extension so that large clearances between the rotor and friction elements are reduced to a predetermined running clearance with few brake applications.  In particular  a pawl engages a toothed member upon a brake application to rotate the toothed member thereby extending an exten-sible member which limits retraction of the friction elements to a predeter mined running clearance after a brake application.  Keys on the pawl are engageable with the toothed member.  These keys are radially disposed to each other so that different rates of rotation are provided for the toothed member thereby varying the rate of the extension of the extensible member.
