Abstract: Title of the Invention:  FLEXURE SUSPENDED GYRO UTILIZING                    DUAL SALIENT POLE MAGNETS                  ABSTRACT OF THE DISCLOSURE      The torquer section of a gyro includes a plurality of torquer coils symmetrically positioned within a flywheel.          A pair of parallel spaced radially oriented salient torquer magnets are located within the flywheel and are equidistant to each respective coil.  The magnet pairs increase the flux density within the operating gap between coil and magnets while minimizing fringing flux.  The torquer section is secured to the gyroscope housing by mounting materials which reduce unwanted thermal gradients during rapid warmup and high torquing rates thus virtually ensuring consistent torquer coil position over the operating temperature range..

Abstract: DIVIDER/COMBINER AMPLIFIER     Abstract of the Disclosure A divider/combiner amplifier circuit divides input power through a sectored coaxial line to a plurality of longitudinal parallel channels spaced around the circumference of a cylinder; the power in each channel is amplified by a semiconductor device; and the amplified power is combined in another sectored coaxial line.  A microwave waveguide connected to the input and output of each amplifying device confines the microwave energy of the operating mode to the longitudinal channel formed by said waveguide.  Each waveguide extends longitudinally along the cylinder and each is circumferentially spaced from its neighboring waveguide by a space which forms a cut-off waveguide to the operating mode.  In the event of a failure of one or more amplifying elements, the space allows the failure mode to propagate radially to microwave absorbing material where it is absorbed to prevent reflection back into the longitudinal waveguide and thus effectively isolates the failure to provide a gradual deterioration of the amplifier circuit performance with element failure.

Abstract: 14                  49,566 ABSTRACT OF THE DISCLOSURE   A gas-insulated  circuit  breaker  is  described which  includes  a Y-shaped,  hollow grounded metal  base member formed from a support section and two angularly-extending legs.  A hollow insulating casing is secured to each base member leg.  A stationary and a movable contact, separable from each other to establish an arc therebetween, are disposed in one of the casings, with an insulating gas disposed within both the base member and the insulating casings.  A mechanism is used for directing a blast of insulating gas into the arc established between the separ-ating contact, and includes a piston fixedly disposed in the one casing and a puffer cylinder secured to the movable contact and movable over the piston to compress the gas therebetween.  An operating mechanism is associated with the base member support section for moving the movable contact, and a drive rod insulatably connects the movable contact and the operating mechanism.  The operating mech-anism thus moves the movable contact through the insulating drive rod.

Abstract: ABSTRACT           A process for the delignification of cellulose material in an aqueous alkaline-oxygen medium in a reaction vessel comprises dispersing oxygen into the alkaline medium prior to introduction of the medium into the reaction vessel and continu-ously flowing the alkaline-oxygen medium through the reaction vessel.  The alkaline-oxygen medium continuously flows through the cellulose material in the reaction vessel where the cellulose material is maintained at a consistency of from about 5% to about 15% in the alkaline-oxygen medium and where the reaction vessel is maintained at about atmos-pheric pressure and a temperature of from about 60°C to 100°C.  The continuous flow of medium through the reactor results in reaction byproducts from the delignification reaction flowing from the cellulose material as a waste stream which is continuously discharged from the reactor.

Abstract: PC-BOARD MOUNTED THERMAL BREAKER     ABSTRACT      A PC-board mounted thermal breaker that opens with a snap action is disclosed.  A bimetallic element, connected to the load terminal of the thermal breaker,  rests on an insulated sawtooth surface when the breaker is in the closed position.  A contact blade, connected to the line terminal of the breaker, is pivotably biased downward into electrical contact with the bimetallic element by the action of an overcenter spring.  An overcurrent through the breaker heats the bimetallic element directly and causes it to bend up-wardly, forcing the contact blade to pivot against the bias of the spring.  When the contact blade has pivoted suffi-ciently to move the spring  overcenter,  the  direction of spring bias reverses,  pivoting the contact  blade rapidly upward, and thereby opening the breaker with a snap action

Abstract: ABSTRACT A self-regulating porous heater device regulates the temperature of fluid passing through it.  This device includes at least one layer of a porous material which has a magnetic permeability inversely related to tempera-ture over a given range.  Due to conductor skin effects, changes in permeability cause changes in the depth of pe-netration of a.c. current passing through the magnetic layer.  Changes in the depth of penetration, in turn, re-sult in changes in resistance--the less the depth the greater the resistance--and in I2R Joule heat.  The com-bined result of these effects is to provide more heat where the temperature of the fluid and the layer through which the fluid flow is below a specified temperature which is related to the Curie temperature of the layer. The invention further contemplates a laminate structure including a porous magnetic layer and at least one other magnetic layer or at least one low resistance nonmagnetic layer or a combination thereof, which may or may not be porous.  Other variations in heat generation response can be realized by specially defining the alloy structure or dimensions of a layer or layers in a device.  Significant-ly, by properly defining pore dimensions, the heater de-vice can filter contaminants from a fluid as it flows therethrough.  Means for switching between a normal ope-rating temperature and an elevated temperature for vapo-rizing or burning off contaminants at the pores is also provided.  A tubular structure, as well as a conical structure, of the heater and optional filter device is contemplated.  In a preferred mode, a porous heater de-vice is included in a chemical reaction chamber.  Fluids flowing through the chamber are closely controlled in temperature through each reaction zone by the heater de-vice (through which the fluids flow) and by an optional cooling element.  By defining the structure of the cham-ber and the rate of fluid flow, close control of other reaction parameters can also be achieved.  Such close control permits greater specifity of reaction yield and greater safety in various exothermic reactions.
