Abstract: Abstract of the Disclosure In order to convert a standard manually controlled bar tacker type sewing machine to automatic numerical control an assembly to constructed which consists of a stepping motor drive system operatively connected to the work clamp positioning levers through gear sectors mounted on pivot arms. In this manner rotation of the stepping motor? causes movement of the work clamp along two axes similar to the motion caused by a style caps.  The style cam is therefore eliminated.  Collateral functions such as nipping and thread cutting are initiated by the  knife cam which is driven through a clutch by the cam shaft.  In order to remove the restrictions caused by gear ratio and cam size and shape, the knife cam is engaged only for the first and last few stitches of the tack design.  The control system, therefore, initiates and times the positioning of the work clamp, starting and stopping of the machine and engagement and disengagement of the knife cam.

Abstract: VARIABLE FLUX-RESET FERRORESONANT VOLTAGE REGULATOR             Abstract of the Disclosure A thyristor controlled ferroresonant voltage regulator in which The output voltage is made adjustable by varying the reset flux level of each of two parallel magnetic core paths upon which the load windings are wound.  Decoupling from the alternating current source is provided by a separate inductor.  The two core paths are decoupled by magnetic shunts, which provides an inductance which may be designed to obtain a soft com-mutation characteristic for the ferroresonant capacitor.           During one half cycle of the output waveform one thyristor is enabled by an associated control circuit to complete a circuit path for the resonant capacitor through a winding on the second magnetic core path, while the flux in the first magnetic core path is clamped; in the second half cycle, another thyristor is enabled at a time determined by the control circuit, to complete a circuit path for the capacitor through a winding on the first magnetic core path while the flux in the first magnetic core path is clamped.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved air stripping device for stripping copy sheets from the surface of an elastomeric fuser roll surface in which copies are fused under heat and pressure.  The improved air stripping device utilizes the deformation in the elasto-meric surface resulting from the pressure to strip the copy sheets without directly contacting the fuser roll surface.          One or more apertures are formed in the tip portion of the stripping device which are connected to a source of air pressure. The tip portion can be either flat or curved and is positioned at an acute angle relative to tangential direction from which the copy sheet is stripped from the fuser roll surface which undergoes a rippled effect from the air pressure to facilitate the stripping of the copy sheets therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE:          Process in which a regulatable quantity of water is blown into the reduction-oxidation zone of a combustion chamber together with and through the secondary air and in which an oxygen excess sufficient for the subsequent burning of unburnt material is introduced into the combustion chamber.  The co-oxidation of the unburned material is catalytically accelerated by a homogeneous water gas reaction and simultaneously the laminar flow of the combustible gases is converted into a turbulent flow for mixing the gases in the combustion chamber,  Also according to this process, a predetermined maximum gas temperature and a water content of at least 10 Vol. % is maintained in the flue gases prior to their discharge from the combustion chamber. There is likewise disclosed an apparatus for performing the process, wherein at a mixing nozzle for the secondary air and the water is provided in one of the two furnace side walls as well as in the heat reflection wall of the combustion furnace overlying the final combustion zone of the combustion grate.

Abstract: ABSTRACT OF THE DISCLOSURE         A line card circuit providing supervisory functions in a key telephone system is disclosed.  Two multi-contact relays perform all of the switching functions required to operate the audible and visual signaling devices used to indicate incoming calls, busy lines, and held calls, and to switch a shunt impedance across the line conductors to maintain line current when a call on that line is being held.  Ringing voltage and line current are sensed by semiconductors which comprise the combination of light-emitting diodes and an adjacent light-responsive semiconductor switch.  These optical semiconductors are interconnected with other semiconductor devices to form a logic circuit for actuating the two control relays, and for disabling the line current detec-tion circuit when the associated line is being held.
