A damper control is employed in the exhaust duct of a bakery oven to maintain constant air mass flow through the duct during a baking cycle to ensure even baking conditions. The damper control can include a pitot tube from which velocity pressure can be derived, and a pneumatic or electronic control loop to move an exhaust damper in the exhaust duct as necessary to keep the velocity pressure constant.

A bakery oven, of the type employing a continuous spiral conveyor for carrying goods to be baked through an oven enclosure, employs an air distribution system to direct heated air from near the top wall of the oven enclosure to a plenum chamber, and from there through an air distribution network to at least certain ones of the tiers of the spiral conveyor. Preferably, heater elements are disposed beneath alternate ones of the tiers of the conveyor system within the oven enclosure, while the air distribution pipes are disposed beneath the remaining tiers. This arrangement serves to decrease fuel consumption for the burners, thereby increasing productivity, and further serves to decrease the stratification of heat layers within the oven enclosure, thereby providing uniform baking conditions throughout the oven enclosure.

A stator for an electric motor includes first and second rows of conductors arranged concentrically around an axis inside a steel core. Each conductor includes a linking end. The stator also includes a first dielectric shim ring arranged between the two rows of conductors. Each conductor of the first row is bent in either a clockwise or a counter-clockwise direction relative to the axis and each conductor of the second row is bent in the opposite direction. The linking end of each conductor of the first row is attached to the linking end of an adjacent conductor of the second row after the conductors are bent. The first shim ring separates the first and second rows of conductors when the conductors are being bent, and is also at least partially disposed between the first and second rows of conductors when the linking ends are being attached.

A processor is described which is particularly useful in a cell which cell forms part of a network for sensing, communicating and controlling. The processor includes a plurality of sets of registers, each associated with a different processor. Each set of registers shares a single ALU. Data associated with each set of registers is simultaneously moved through a path which includes the registers, ALU, and memory.

A bar wound stator assembly includes a connection module attached to a stator core at a weld end of the stator assembly. The connection module provides all required electrical connections to connect shaped plurality of hairpin bar connectors of the stator assembly within a first pole pair of a winding set of conductors. All of the hairpin bar conductors include an identical span. The connection module completes each phase of the winding set, to connect each phase of the winding set to define a connection configuration, e.g., a wye or a delta connection configuration, and to connect the stator assembly to all external connections.

A system and method of conveying objects. A switching station is operated in coordination with gaps formed in a first product stream carried on an upstream conveyor, to split the first product stream into two or more second product streams carried on downstream conveyors.

An autocollimator having particular utility in optical aiming systems for the cannons of battle tanks comprises a pair of light sources for directing two beams of light along different paths towards a light reflector mounted, for example, on the muzzle of a tank barrel. The two beams of light are thus reflected along different paths towards a position sensitive light detector suitable for providing an output electrical signal indicative of both the receipt thereon of one or both of the reflected light beams and the position of the light beams on the light detector. The light sources are alternately turned on and off in non-overlapping time periods to provide identification of which of the two beams is being detected by the light detector.

A method of joining the ends of wire windings for a motor stator or the like includes preparing a surface at each end (e.g., by removing any enamel coating), deforming the surfaces to produce knurls, striations, and the like, and then ultrasonically bonding the two surfaces to produce the bond between windings, thereby providing a joint with improved strength.

In systems embodying the invention, a battery powered collimated light source is located at the muzzle end of a cannon and is beamed back over the length “L” of the cannon gun tube to the collecting aperture of an optical transceiver located near the breech end (or trunnion) of the cannon. The turn-on and turn-off of the collimated light source is under the control of the gunner of the tank or the tank's fire control computer system to ensure that the battery power/energy is used only when deemed necessary by the user so that battery power is conserved.
