Abstract: AUTOMATIC TWO-WAY CENTRIFUGAL CLUTCH FOR MOTOR DRIVEN APPARATUS ABSTRACT OF THE DISCLOSURE An automatic two-way centrifugal clutch having a pair of clutch members mounted for pivotal movement on a rotating drive member is disclosed. Each clutch member has a first state in which driven surfaces are in contact with a clutch drum interior friction drive surface; a second state in which the clutch members are out of contact with the drum frictional drive surface; and a third state in which clutch driving surfaces are in driving contact with the frictional drive surface. At least two spring members are connected between the clutch members, the springs urging, when the speed of rotation of the drive member is below a first selected speed, the clutch driven surfaces against the frictional drive surface. When the rotational speed of the rotating drive member is greater than the first selected speed, centrifugal force overcomes the spring force and urges the clutch members, which are mounted symmetrically with respect to the rotation axis, to pivot to a position wherein the clutch driven surfaces are out of engagement with the frictional drive surface. If the rotation speed is greater than a second selected speed, the centrifugal force urges the clutch driving surfaces into driving contact with the friction drive surface. By an appropriate choice of springs and spring position, a significant and distinct idle range, which is substantially independent of the device manufacturing tolerance, is defined.

Abstract: EFFICIENCY HEATER                         ABSTRACT          Three elements are secured together in new and unique fashion to form a heating unit, movable and installable as an integral unit and capable of obtaining maximum BTU's from the fuel used.  These elements are (1) an outer jacket, which defines the design and outline of the heater, (2) an inner jacket, forming with the outer jacket a residual burning chamber, narrow in cross section and relatively high in vertical extent to provide maximum heat transfer surface, and (3) an A- or tent-shaped fire box or combustion chamber, enclosed by and secured to the inner and outer jackets.  The tent-shaped fire box extends from the extreme lower end of the heater to its upper limit.  The edges of the walls of the fire box are secured to outer and inner jackets in sealed relationship, dividing the areas within the heater into heat producing and heat conducting areas and clean air passage-ways.  The configuration of the inner jacket 14 is an incomplete cylinder. It has separated edges, each slanted to conform and attach to one of the slanted walls of the fire box.  The broken away areas of the cylinder is triangular.  One edge of the triangle is secured to an edge of the fire box wall.  The other edge nests and attaches to the outer surface of the opposite wall and in the vacinity of a final vent.  Thus access is provided to the residual burning chamber from the interior of the fire box, and egress therefrom is provided in the form of a final vent.  The residual burning materials are thus conducted in a circular path around the clean air passageway, thus all possible energy units are extracted from whatever fuel is used.

Abstract: ABSTRACT A track and hold system for use with a test instrument such as a multimeter includes an input circuit, a buffer amplifier, a storage device such as a capacitor, an output amplifier, an output circuit, a detector for detecting a pulse on a signal passing from the input to the output, and a switch responsive to the detector for isolating the storage device from the input circuit but not the output circuit for a predetermined period.  The system also includes a timer responsive to the detector to provide an isola-tion command to the switch for the predetermined period.  Further, the system includes a delay circuit, responsive to the detector, for interposing a delay of variable duration prior to activating the timer.  In a preferred embodi-ment, where the system is used in conjunction with a multimeter having a "hold" circuit which directs the meter to display the last-measured signal, an output is provided to the hold input of the meter directing the meter to "hold" for predetermined periods whenever the switch opens or closes.  The "hold" output circuit is also used to provide indefinite retention of a read-ing and trigger lockout for the detector circuitry.

Abstract: ABSTRACT A process for preparing starch-containing rayon fibers by forming a slurry of starch granules in an aqueous medium, adding an aqueous solution of a starch chain-splitting agent thereto, adding sodium hydroxide to produce an aqueous alka-line solution of the starch and agent, blending the alkaline solution with viscose and extruding the starch-containing vis-cose thus obtained to form starch-containing rayon fibers. These fibers have improved fluid holding capacity and are use-ful in making fabrics or material where fluid capacity is an important requisite. The use of higher starch concentrations allows a reduction in the amount of dissolved cellulose pulp used in the production of these rayon fibers and thus provides a more economical process for the production of such fibers.

Abstract: ABSTRACT OF THE DISCLOSURE         A burner cut-out safety control for a combustion heating device having an automatic exhaust flue damper.  The safety controls act to discontinue burner operation in the event the damper actuator device or controls fail, or other flue blockage causes products of combustion to be exhausted through the draft diverter inlet opening.  The control is integrated with an existing burner pilot safety circuit and pilot valve to cause the pilot valve to be closed in the event combustion gases begin to pass out of the flue through the draft diverter inlet opening, this condition being detected by a lineal temperature sensor extending about the draft diverter inlet opening, which senses combustion gas spillage by the resultant heating of any portion of the lineal tempera-ture sensor.  The lineal temperature sensor is placed in series with the pilot burner ignition temperature sensor to cause closing of the pilot valve, located ahead of the main gas valve activated by the burner controls during normal automatic operation of the burner.  The fuel supply is thus cut off even if the main gas valve fails.  A second tempera-ture sensor is located in the plenum of the warm air ducting as a secondary safety control feature also acting to cause the pilot valve to close in the event of an excessive tempera-ture being sensed in the warm air plenum.

Abstract: CATALYTIC HYDROCRACKING OF HEAVY OILS            Abstract of the Disclosure An improved process is described for the hydrocracking of heavy hydrocarbon oil, such as oils extracted from tar sands.  The charge oil in the presence of an excess of hydrogen is passed through a tubular hydrocracking zone , and the effluent emerging from the top of the zone is separated into a gaseous stream containing a wide boiling range material and a liquid stream containing heavy carbons.  According to the novel feature, the hydrocrack-ing process is carried out in the presence of a catalyst consisting of finely divided coal or other carbonaceous material carrying catalytically active metals from VIA and Group VIII of the Periodic Table of Elements, e.g. . cobalt and molybdenum.  The catalyst is slurried with the charge stock and has been found to greatly reduce coke precursors and thereby prevent the formation of carbonaceous deposits in the reaction zone while also being effective in reducing the sulfur concentration of the product.

Abstract: ABSTRACT OF THE DISCLOSURE           Four PIN diodes are connected, two in parallel oppositely directed at each of two ports of a 3 db, quadrature bybird which equally divide the power from an input port.  The mismatch produced by the PIN diode resistance in parallel with the matching load resistance reflects part of the power, which combines at the two ports and exits at a fourth port of the hybrid.  Direct-current bias to the PIN diodes is adjusted to vary the attenuation.  There is also variable resistance and capacitance which serves as variable adjustments on the termina-tions of the hybrid when the diodes are unbiased.
