Abstract: ABSTRACT OF THE DISCLOSURE          In an explosive powder operated setting device or gun for driving fastening elements, such as bolts, studs and the like, into a hard receiving material, the amount of explosive gases used in the driving operation is regulated by a control member located in the setting gun.  The control member is conically shaped and fits into a conically shaped surface in the bore of the gun.  The conical member is rotatably mounted in the bore between the firing chamber and an exhaust duct for regulating the amount of explosive gases diverted to the duct instead of being used in the fastening element driving operation.

Abstract: Abstract of the Disclosure The following specification describe's a magnetic assembly for use in controlling the main contacts of a circuit breaker.  The magnetic assembly includes a yoke, an armature for attraction to the yoke to move an operating lever and a pivotable adjustment arm.         The lever operates the trip crossbar, which opens the main contacts and is in turn pivotably carried by the adjustment arm.  One end of the operating lever is held against longitudinal movement relative the trip crossbar, when the adjustment arm is pivoted to calibrate the circuit breaker.  The lever therefore pivots on the adjustment arm to move the armature towards or from the yoke to control the armature air gap without altering the lever travel distance to the crossbar.  The armature is also mounted on the lever for relatively linear movement in relationship to the yoke.  The main contacts include a stationary contact, which is engaged by the mass of a spring supported floating arc quenching magnet that serves to absorb the shock of contact closure for reducing contact bounce.

Abstract: ABSTRACT OF THE DISCLOSURE     Clandestine signals are transmitted by using a surface wave acoustic device to disperse the spectrum of a pulse-modulated CW carrier.  The dispersed signal is itself modulated and then transmitted to a remote location, at low level.  At the remote location, an acoustic device of conjugate characteristics is used to recover the dispersed signal from out of the background noise.

Abstract: FURNACE WITH RADIANT BURNDOWN TUBE                Abstract A radiant burndown tube for furnaces which have a chamber sealable from the ambient atmosphere and in which there is a combustible gas.  The burndown tube is divided into three func-tional areas; the burner leg, the exhaust leg and a tube portion.          The tube portion is located within the furnace chamber.  There is an inlet where the combustible gas from the furnace chamber is drawn into the burndown tube.  The combustible gas is mixed with air and ignited in the tube and the combustion products are exhausted via the exhaust leg.  Thus, the heat energy normally lost in the burndown of combustible furnace exhaust gases out-side of the furnace is captured and used to provide additional heat to the furnace.

Abstract: Abstract of the Disclosure Polymeric structures having interpenetrating matrices in cured form comprising an epoxy-polyamine network and a polysiloxane network.  The interpenetrating network physical and chemical properties are improved over those of either polymeric component alone.  The network can be prepared by simultaneously reacting epoxy resin having at least two oxirane groups with amine curing agent, and having present at least 0.1 equivalent of silane, water being substantially uniformly distributed throughout the mixture in an amount sufficient to bring about substantial hydrolytic polycondensation of the silane to form a cross-linked interpenetrating polymer network.  The amine curing agent may be substituted wholly or in part by aminosilane. Sources of silane may include aminosilane and epoxysilane. Relative reaction rates of formation of the polymeric networks are controlled, to get good intertwining of the two polymers.
