Abstract: ABSTRACT OF THE DISCLOSURE   An arrangement for preventing overheating in electric air heaters of the type having a plurality of electric heating elements disposed in a casing defining a vertical air flow path having a lower air inlet and an upper air outlet includes the placement of a temperature sensing device in a vertical air channel located adjacent and external to the casing.  The vertical air flow channel communicates with the vertical air flow path intermediate the inlet and outlet via an aperture in the casing wall. A flow duct is provided in the casing below the aperture for preventing, during normal operation of the heater, heated air from the interior of the casing from reaching the sensing device in the air channel.  If the outlet of the flow path is obstructed, a portion of the hot air will travel from the casing through the aperture to the sensing device to activate the sensing device to deenergize the heating elements.

Abstract: OPTICAL FIBER POWER TAPS          Abstract of the Disclosure There is disclosed a variety of arrangements for tapping a portion of the signal power from an optical fiber waveguide without requiring that the fiber be terminated or broken.  Power is coupled out of the fiber waveguide, which typically includes an inner core surrounded by a lower refractive index outer cladding, by disposing a dielectric body in a coupling relationship with an intermediate length of the fiber from which all or most of the cladding has been removed or, alternatively, which is bent to cause a portion of the power to radiate out of the inner core into the outer cladding of the fiber.  The dielectric body couples power out of the fiber provided its index of refraction is approximately equal to, or greater than, that of the fiber cladding material.  The power coupled out by the dielectric body is converted to a representative electrical signal by a photodetector disposed adjacent to the dielectric body.

Abstract: "MECHANICAL DRIVES"      ABSTRACT A compact high-torque mechanical speed changer, which of-fers a very wide range of output speeds in different angular directions through selections from sets of fully-interchange-able planet and sun gear combinations, and in which one pre-determined counterweighting unit provides matching for the eccentricities associated with all the planet gears of such sets, comprises two sets of planet and sun gear combinations each having a one-tooth difference in numbers of effective teeth, the two externally-toothed planet gears being coupled together angularly and being mounted for eccentric rotation relative to a supporting input crankshaft, while the associated internally-toothed sun gears are respectively fixed with the changer housing and with an output member rotatable collinearly with the input shaft.  Planet-gear teeth or lobes are of epitrochoid curvature, and all of the planet gears of such sets are of the same diameter; concomitantly, the companion sun gears, which are preferably of the type involv-ing discrete roller-pin teeth rather than continuous-curvature teeth, are of the same diameter and only the number of such rollers varies from set to set.  In other dimensional respects the gear sets are substantially identical and can therefore be interchanged to effect different ratios and directional senses of input to output speeds.  A counterweight offsets the input-shaft and planet-gear eccentricities, and serves any selected planet gears from such sets.  The changer housing and interior mountings for gear combinations accommodate assembly of sets, as desired, to yield various speeds and directions of output.

Abstract: SERIES PARALLEL TRANSITION FOR POWER SUPPLY          Abstract of the Disclosure An AC generator or other AC source has two identical output sections which are connected through corresponding rectifiers to drive a DC load such as a group of DC traction motors connected in parallel for driving a locomotive.  The rectifiers are selectively placed in parallel to provide a high current low voltage mode and in series to provide a low current high voltage mode, thus furnishing a wide range of voltage and current at a given power level to satisfy a broad range of motor requirements with a power source of limited size and capability.          To effect smooth transition, one of the rectifiers includes SCR's to modulate the rectifier output voltage.  During transition that rectifier is phase back to zero voltage, allowing the other rectifier to supply the full load requirements and then the rectifiers are switched from series to parallel or vice versa whereupon the modulated rectifier is returned to its full voltage.          Whenever the rectifiers are in series, the modulation of the one rectifier is accomplished gradually to allow the other rectifier time to take on added voltage.

Abstract: ABSTRACT           A portable power tool or appliance, such as a cordless grass shear, may be slidably received within a unitary stirrup. A flexible flap on the stirrup carries a detent button that is automati-cally snapped into a screw-hole on the clam-shell power tool housing, as the power tool is fully seated within the stirrup, The flap may be flexed manually to release the detent button, thereby facilitating quick disengagement between the power tool and the stirrup. The stirrup carries ground-engaging wheels to facilitate manual movement and guidance of the power tool during its stand-up operation. An extension handle in the form of a tubular wand is secured to the stirrup and extends upwardly therefrom. A top handle with a switch is provided on the end of the wand, An electrical cable is connected to the switch, extends downwardly therefrom within the wand, and exits from the stirrup above the power tool. The end of the cable carries a plug adapted to be received within a receptable on the power tool. The receptable has spaced contacts formed as a con-tinuation of the contacts of the tool switch. This provides a parallel connection, bypassing the tool switch and, at relatively low cost, facilitating manual control by the switch on the top handle.
