Abstract: Title:        VAULT GRID            Inventors:  Charles U. Deaton Lloyd H. Anderson ABSTRACT OF THE DISCLOSURE A grid which produces a vault like appearance on one side comprises a first series of parallel plates extending in one direction and a second series of parallel plates extending in the direction to intersect the first series of plates.  At least one of the series of plates is generally concave on the one side; when only one series of plates is generally concave on the one side a tunnel effect is pro-duced, but when both series of plates are generally concave on the one side, a dome appearance is produced with the side edges generally concave.  The grid may be used as a ceiling grid and illuminated, if desired, or as an upright partition or divider placed on one edge.  The opposite edges of the plates may be equidistant, including any deviations from a curve on which the edges may be laid out.  A series of scallops, concave on the one side and convex on the opposite side of each plate may have the length corresponding to the distance between intersecting plates.  When used as a ceiling grid, illuminated from above, the distance between plates of each series may be, and, when a tunnel effect is produced, is proportioned so that the angle of cutoff of light is the same.

Abstract: PRINT PIN ACTUATOR AND METHOD OF MAKING SAME     Abstract of the Disclosure The high speed print pin actuator disclosed herein is constructed as two sub-assemblies, a U-shaped fixed magnet structure and an armature sub-assembly.  One leg of the U-shaped structure constitutes a coil core and the other includes a permanent magnet and a keeper plate, the ends of the keeper and the core being finished to a common plane.  The armature assembly includes a flux return bridge structure which extends from the keeper to a region adjacent the end of the coil core and which is bifurcated to receive an armature which is selectively attracted to the coil core.  The armature is carried on a spring which is, in turn, mounted on the bridge structure.  With the spring in a deflected position, the armature is finished to a common surface with the portion of the bridge which mates with the magnet structure.  Accordingly, assembly of the armature sub-assembly with the U-shaped fixed magnet structure is facilitated and accurate parallelism of the armature and pole piece is provided.          Preferably, a thin shim of a wear resistant material is inter-posed between the spring and the bifurcated portion of the bridge structure.

Abstract: A B S T R A C T           Bales and/or packs of dried tobacco leaves, parts of tobacco leaves and/or reconstituted tobacco, which are compacted for convenience of shipment from the maker to the processor, must be broken up prior to the making of cigarettes, cigars or cigarillos by separating the particles from each other.  This is accomplished in part by subjecting the bales, packs, portions of bales and/or portions of packs to the action of microwaves which are furnished by adjustable microwave generators and enhance the tendency of the particles to become separated by reducing the force with which the particles adhere to each other.  The bales and/or packs can be transported past a battery of microwave generators, and the temperature of the bales and/or packs is monitored to adjust the microwave generators when the temperature is outside of a preselected range.  The treatment by microwave generators is followed by a mechanical treatment which ensures permanent separation of particles from each other, and the mechanically separated particles are thereupon introduced into a moistening apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE   A paper feed system in a printer includes a platen for supporting a recording paper sheet, a paper feed drive motor, and a transmission gear mechanism for transferring the rotation of the paper feed drive motor to the platen so as to conduct an automatic paper feed operation. The paper feed system further allows a manual paper feed operation wherein the platen is manually rotated.   A detection system is provided which detects the manual paper feed operation. If the manual paper feed operation has been conducted before the automatic paper feed operation, a compensating paper drive is first con-ducted when an automatic paper feed instruction is developed. In the compensating paper drive, the platen is first driven to rotate in a reverse direction by a predetermined amount and then to rotate in a forward direction by the same amount, thereby compensating for the displacement of the paper sheet location caused by the backlash of the transmission gear mechanism during the manual paper feed operation.                   * * * * * * * * * *

Abstract: ABSTRACT    The invention provides a turf aerator wherein a plurality of tyne arms, having tynes attached to their lower ends, extend substantially vertically downwardly from the cranks of a crankshaft located transversely of the direction of travel of the aerator.  The aerators may either be self propelled or towed behind a tractor in which case a drive linkage connects the crankshaft to the power take-off of the tractor and is driven such that, as the aerator is moved forward, the crankshaft moves with the lower arc of its rotation in the rearward direction.  In the case of a self propelled aerator a motor is provided to both propel the aerator and to drive the crankshaft.  The length of the tyne arms is such that they are projected into the ground as the respective crank moves through its lower arc and they are lifted clear of the ground as the crank moves through the upper arc of it's travel.  While the tynes are engaged with the ground, the tyne arm is maintained in a substantially vertical orientation by the rearward motion of the respective crank through the lower arc of its rotation.  The lower end of each tyne arm extends through a slot running longitudinally of the aerator such that lateral movement of the tyne arm is prevented.  Each tyne arm is biassed toward the forward end of it's slot by a spring and the tyne arm moves reardwardly in the slot when the tyne is engaged in the ground due to the forward motion of the aerator over the ground.  When the tyne is retracted from the ground by the crankshaft the tyne arm is returned to the forward end of its slot by the spring.  In operation the tynes penetrate the turf with a reciprocating action, individual groups of tynes being staggered in their operation relative to other groups of tynes such that, at any one time, at least some of the tynes are in engagement with the ground, while others will be clear, thereby distributing the effort of driving the tynes into the ground over a full revolution of the crankshaft.          The tyne battery is raised and lowered by hydraulic means to allow ground clearance during transportation.

Abstract: Abstract:         An idle speed control device for an automobile engine has an electromagnetic driving portion and a flow rate controlling portion disposed in a bypass passage formed in a throttle chamber so as to bypass a throttle valve.  The flow rate controlling portion has a body defining a passage for the air to be controlled, a seal formed in an intermediate portion of the passage, a first valve driven by a plunger of the electromagnetic driving portion through a rod so as to be brought into and out of contact with the seat.  A sleeve is disposed in the body, and a second valve is connected through the rod to the downstream side of the first valve so as to produce a vacuum force that acts in the opposite direction to the vacuum force produced on the first valve whereby to absorb any fluctuation in the intake pressure in cooperation with the first valve.  The second valve is loosely received in the sleeve.  By this arrangement, it is possible to eliminate any unfavourable effect of the fluctuation in the intake vacuum on the actual air flow rate.  In addition, since the flow from the vacuum compensating portion is minimized, vacuum compensation is made possible without incurring any increase in the initial leak.
