A composite signal comprising an analog signal with transient pulses superimposed thereon is periodically sampled and each sample is converted to a digital value which is stored in a buffer register prior to transfer to a data processing unit. A special circuit comprising a differentiator and comparator continuously receives the composite signal, detects the transient pulses, and forces a value into the buffer register to represent each transient pulse, even though the pulse may occur during an ...

A mechanism suitable for securing and locking the posting board of a mechanized filing cabinet having a position adjustable posting board is disclosed. The posting board is maintained at a desired elevation by a pair of locking rods that normally project outwardly through apertures in the frame of the filing cabinet. When it is desired to change the position of the posting board, a release handle is moved outwardly. Movement of the release handle outwardly moves the locking rods inwardly and all...

A plurality of finger-like dispensing arms are mounted for pivotal movement back and forth along a path over a slot in the bottom of a toner dispenser hopper. The degree of pivotal movement controls the amount of toner dispensed. A linkage including a cam follower arm is provided for driving the dispensing arms in one direction in response to rotation of a continuously rotating cam. Springs provide the force for driving the dispensing arms in the opposite direction and for holding the cam follow...

A vacuum-type sheet feeding device is described which comprises a reciprocating shuttle plate having a gated vacuum groove. In operation, as suction is applied to the groove and a sheet to be fed is thereby sucked into the groove, the vacuum gate, which closes off one end of the vacuum groove, yields to allow the sheet to move into the groove. The sheet feeding apparatus also includes a sheet magazine which comprises a separating ledge for supporting a bottom front corner of a sheet stack, a suc...

A xerographic copy machine is provided with an elongated web for wiping toner particles from the surface of a rotating xerographic drum. The web is supported by supply and take-up rolls carried on a pivotally mounted bracket. The bracket is spring biased to hold the web out of contact with the drum surface when the machine is idle. When the machine is turned on a electro-mechanical clutch is energized to rotate a latching mechanism including a cam and arm. The cam pivots the bracket to bring the...

A floor-type billiard game is described wherein a rectangular playing surface has a length dimension range of from 8 to 12 feet, a width dimension range of from 6 to 8 feet and a length-to-width ratio of less than 2. Playing balls for the game are approximately the same size and composition as standard billiard balls. There are two oppositely-disposed, off-center side pockets which are closer to a spotting end of the playing surface than to a scratch-line end, and two side-by-side center end poc...

An apparatus and method are described for packing a plurality of containers in a case at a packing station. The apparatus comprises a plurality of suction cups mounted on vacuum manifolds suspended between two flexible endless transporting chains which are laterally spaced from one another. Containers are deposited on the vacuum cups and a vacuum is applied to the manifolds. The transporting chains are then driven to invert the suction cups and gripped containers. The vacuum is then disabled and...

A plurality of rods are assembled in a predetermined configuration to form a core which is surrounded by a molten matrix metal within a heated crucible. The temperature of the thusly charged crucible's upper portion is maintained above the matrix metal's melting point. In this respect, as the heat is applied to the top of the melt, the crucible is maintained in a hot environment while the bottom of the crucible is centrally chilled. In this manner the charge is solidified from the bottom toward ...

A tapered object attitude sensing and turning system is described wherein a sensor assembly includes a detector head comprising a butt-end and a tapered-end pivotal feeler arms for making contact with the same side of each tapered object passing the detector head. The feeler arms have freedom of movement such that contact with tapered objects causes them to pivot outwardly. In addition, a mechanical linkage between the feeler arms causes the tapered-end feeler arm to pivot in response to pivotin...
