Abstract: Bundled signatures are placed on a first set of conveyor belts which move the signature bundle to a shingling station. A pair of side belts at the shingling station are spaced so that the signatures are individualy bowed forwardly upon encountering the belts so as to separate each signature from the other signatures of the bundle. A third set of conveyor belts move the bowed signatures upwardly in a shingled condition from a discharge site of the side belts.

Abstract: A machine for arranging signatures in bundles includes a receiving conveyor onto which the signatures are initially directed, and this conveyor moves the signatures in a shingled condition between deflecting surfaces which cause the signatures to simultaneously bow forwardly and rise at their leading edges so as to assume an edge-standing condition. The edge-standing signatures move onto a consolidating conveyor which advances them at a lesser velocity so that they move closer together, and here the signatures are also jogged into marginal registration. At the end of the consolidating conveyor the signatures pass onto an accumulating conveyor which normally advances the signatures at a slightly lesser velocity than the consolidating conveyor, so that the signatures pack together.

Abstract: A method and apparatus for high speed pouch or bag making from thin, heat-sensitive thermoplastic film webs or multiply webs of paper, film and foil in which the seal pattern may be simple or complex sealing and in which the method is applied to a continuously moving web and sealing is achieved at temperatures below the softening temperatures of the film or the sealing interfaces. A method of forming an open pouch comprising the steps of continuously driving an elongated web of pouch forming material at a constant speed along a pouch making path which extends continuously through a web coating station, a web collating station, an E.B. curing station and a web cutting station. A pattern of a coating is applied to a first surface of a first continuous web of pouch forming material as it is driven continuously through the web coating station to render the interface bondable at a seal line and non-bondable in the area of the storage compartment when subjected to electron beam radiation.

Abstract: A machine for stacking and bundling flexible sheets, such as the signatures that are delivered from a printed press, includes a succession of aligned conveyors. The sheets are deposited on the first conveyor where they accumulate in a generally horizontal disposition, one on top of the other, and the first conveyor withdraws sheets from the bottom of this pile and conveys them to a gate in a shingled condition. At the gate, which is narrower in width than the sheets, the sheets bow forwardly and rise upwardly at their leading edges until they stand on edge. It is in this condition that the sheets pass onto a second conveyor which moves them through another gate that is narrower than the first gate, so that the degree of bowing increases. The second conveyor moves slower than the first conveyor and as a result the flexible sheets consolidate in the upright condition on the second conveyor.

Abstract: A process for avoiding compaction and permeability reduction in carbonate formations when fluids are injected into such formations in a manner to produce hydrocarbons from such formations. The process involves controlling the pH and the state of mineral saturation of the injection fluids.

Abstract: A tapping accessory for use with the chuck of a rotary-operated machine such as a drill press or lathe in which a tap tool is detachably secured to one end of a body, and a first guide element is on the other end of the body. A second guide element is telescopically related and rotatively mounted to the first guide element on a longitudinal axis and is adapted to be gripped in the chuck of the rotary-operated machine. A handle is detachably secured to the body between the tap-connecting assembly and the guide elements for turning the body and tap tool manually about the axis of the guide elements. More particularly, the first and second guide elements are at the same side of the handle, while the tap-connecting assembly is at the opposite side of the handle. In one embodiment, the first guide element is a socket in the said other end of the body, while the second guide element is a spindle slidably and rotatively received in the socket.
