Abstract: The invention relates to safety glass comprising a silicate glass layer and a coating of an elastic material forming a protective layer on at least one side of said glass layer. The coated side has a delineated area formed of a relatively hard, scratch-resistant material to which a label may be removably attached. Thus, when the label is removed, the protective layer is not damaged.

Abstract: A cutter for cutting continuous stock materials into discrete lengths is disclosed. The cutting device includes a plurality of rotatable cutting tools or blades extending transversely across a cutting zone. The cutting tools are mounted in a common plane, are intermeshed, and are synchronously driven in opposite directions. The cutting zones of the intermeshed cutting tools overlap and thus the cutting device is capable of performing the cutting operation by movement in one direction through the material being cut. The cutting tools have opposed segments that carry cutting edges. In one form of tool, the cutting edges are spaced from the axis of rotation of the cutting tool by a distance that continuously increases in a direction opposite the direction of rotation of the cutting tool. This change in distance can be related to the speed of rotation of the cutting tools and the speed at which the cutting tools are advanced through the material being cut.

Abstract: A process and apparatus for strand transfer is disclosed. The transfer occurs during the exchange of two winding collets in which the first, full collet, is shifted to the position where it is emptied while the second, empty collet, picks up the strand. According to the disclosure, the linear drive speed of the first collet is reduced; the arc of contact of the strand on the circumference of the second collet is increased as the second collet arrives at the position previously occupied by the first; the portion of the strand travelling from one to the other is engaged between the collets and the engagement of this portion is maintained and progressive breaking of the strand by abrasion is effected until the second collet takes up the strand. A novel device comprising a moveable means capable of introducing and maintaining the strand in position between the two collets and abrading the strand until the transfer has taken place is disclosed.

Abstract: Apparatus and method for winding a continuous strand formed from an attenuable material is disclosed. An end face of a winding collet includes strand-engaging elements spaced about the periphery of the end face of the collet that engage the strand as it is brought against the face of the collet. There are at least three strand-engaging elements on the face of the collet. The strand is conducted from the strand-engaging elements to the starting drum and is wound on the collet until it reaches operating speed. When the winding collet is at its operating speed, the strand is urged onto a winding sleeve to form the winding.

Abstract: A two-cycle internal combustion engine having reed-type intake valving, and specially configured and positioned intake and injector porting, with the porting constructed and arranged to improve various of the operating characteristics of the engine, and particularly adapted to increase the effectiveness of the injection through the injector porting.

Abstract: Carriers adapted to support strand spools in wire type pallets are disclosed. Each carrier comprises a tray having gripping devices or claws for centering the carrier at the intersection of the crossed support wires which comprise the pallet. Tubular supports extending upwardly and downwardly from the central tray are adapted to hold the ends of spools in position on stacked pallets. The lower support is slotted so that it can extend beneath the plane of the pallet. A central bore extending through the supports and the spool tray allows for circulation of air and treatment fluid so that the spools may be treated with steam or other treatment gas while on the pallets.

Abstract: Fuel porting and passage arrangements including transfer porting and passages between the crankcase and the combustion side of the piston, together with intake porting and passage arrangements for delivering fuel to the crankcase. The transfer and intake passages include portions of regions common to both or in communication with each other in relationships providing not only for direct delivery of fuel to the crankcase but also for augmenting fuel transfer into the combustion space.

Abstract: Equipment is disclosed for gas blast attenuation of attenuable materials by the toration type of technique according to which a gaseous jet is directed transversely into a gaseous blast of larger cross section, thereby developing a zone of interaction of the jet and the blast into which a stream of the attenuable material is delivered. Each fiberizing center incorporates a plurality of components including means for generating the jet, means for generating the blast, and means for supplying the stream of attenuable material. In addition, the fiberizing center frequently also incorporates an additional structural element or means positioned along the path of the jet and influencing the jet flow.

Abstract: A thermal fluxmeter is disclosed, comprising a sensor or pick-up incorporating at least one interconnected series of thermocouples, the sensor comprising a board or plate-like element having metallic plating applied to both sides of the element and to the interior surface of the orifices, the plating being divided into local areas and being formed of different metals in different areas thereof to provide thermocouples having low temperature and high temperature junctures at opposite side faces of the sensing element, which junctures are interconnected by plating within the orifices.

Abstract: Method and apparatus for the production of fibrous materials from attenuable substances, particularly molten glass, are disclosed, along with the fiber products which result. In the disclosed system the material to be fiberized flows into a region established as a result of the interaction of a jet transversely oriented with respect to a larger blast, the material being acted upon in the interaction zone to produce a highly attenuated fiber. Method and apparatus are disclosed utilizing a glass admission orifice and jet blast generating devices which are spaced from each other. Moreover, method and equipment are disclosed for forming fibers from attenuable material by the use of high velocity whirling gas currents or tornadoes. Attenuation is preferably effected in two sequential stages, each of which utilizes a pair of high velocity whirling currents or tornadoes, with the gases in the two tornadoes of each pair turning in opposite directions.

The strand is conducted from the strand engaging means to the starting drum and is wound on the starting drum until the winding collet reaches operating speed. When the winding collet is at its operating speed, the strand is urged away from the starting drum and onto the winding collet to form the winding.
