Abstract: A token and photo-detector circuitry in an electronic device used for supplying electrical power to an external appliance for an amount of time represented on the token. The token contains encoded information in a base numbering system in several regions of the token and this information is read by the circuitry to represent a time value whereby the circuit relays power to the appliance for an equivalent length of time. Several tokens may be deposited into the device in any orientation so as to accumulate time for use of the appliance. The device is programmable and can communicate with the user/operator with the appropriate hardware additions.

Abstract: An arrangement in a press feed line for picking up and conveying metal blanks at generally the same rate of speed they exit speed from the press, and automatically stacking them on a stacker car, or the like. The stacker car has a rotatable base supporting a pallet, which in turn supports the stacked blanks, and is designed for sideshifting and raising and lowering of the base, in the stacking station, thereby allowing the desired positioning of the stacked blanks on the pallet and the pallet on the base. Automated adjustable devices which may conform to the configuration of the blank neatly stack the blanks and variations to the arrangment allow more than one blank to be removed from different sources in the press, thereby permitting more than one stack to be made simultaneously.

Abstract: An embedding apparatus for optionally cutting through different densities of soil and rock in order to embed cable in a waterbed. The apparatus comprises a low pressure jet assembly for cutting into the soil, a rock-cutting assembly with teeth for cutting into soft rock; a rock-embedment depressor with a rotary saw blade assembly for cutting into relatively harder rock; and a depth sensor device. The low pressure jet assembly is part of a pivotal soil embedment depressor and liquifies the soil without any permanent soil displacement. The rock embedment depressor is selectively attachable to the soil embedment depressor, and has jets connected to a source of pressurized fluid to provide an hydraulic cushion thereunder and to clear the rock debris for the embedment of the cable.

Abstract: A system for pickling hot rolled carbon steel strip with hydrochloric acid completely and uniformly in optimum time. The system consists of a series of cells made up of a number of section modules, each having a straight narrow passageway with monolithic top and bottom walls through which the strip and pickling liquor travels and a pair of cooperative conduits in the top and bottom walls for introducing the fluid into the passageway. A wringer roll assembly with motor driven wringer rolls push the strip through each cell and consists of a housing having walls closely spaced to the rolls and a sealing element in the walls for the concentration of acid in each individual cell. The rate of pickling on the strip is increased due to the turbulence of the circulating pickling liquor within each cell, the higher temperatures, and the high concentration in each cell; the latter two of which are due to the design of the section modules.

Abstract: A handle for a luggage case made of two longitudinal spaced apart rows of heavy cord of twisted material with an outer piece of fabric material folded longitudinally around the two rows and sewn along a longitudinal centerline to form a strap. The cords are centrally located and of a length such that it determines the length of the handle and forms a substantially rigid, padded central portion of the handle. The opposite ends of the formed strap are free of the corded fabric, are slid through attachment loops, and folded under until the ends substantially come together thereby forming a lower and upper layer for the handle. A sleeve is wrapped around the juncture of the ends, and both upper and lower layers are fixed together.

A computer preferably has stored information regarding the desired shape and gauge effects a comparison between the signals received from the shape and gauge sensors.Gauge sensors may be provided adjacent to the shape sensors. The mill stands preferably have roll bending cylinders positioned by roll bending system servo-valves which are actuated by signals from the controller.

Abstract: An arrangement for winding material onto a coiler drum along a passline of a hot reversing mill comprising an apparatus having two pivotal arms mounted on a common shaft and movable in a different arcuate path toward and away from the coiler drum. Rollers at the end of the arms tightly enwrap the material around the drum when the arms are positioned against the drum as the material is being underwound onto the drum. The roller of one of the arms may act as a deflector roller when positioned away from the drum as the material is being overwound onto the drum. The other arm consists of two wrapper rollers on a pivotal mounting for their proper orientation around the drum and for flat passes of the material through the mill. This other arm is positioned away from the drum below the passline to allow a retractable table roll assembly consisting of a plurality of table rolls to be positioned in the passline for supporting the material.

In addition, a length of strap may be arranged along the length of the hand-grip member to add rigidity thereto. A piece of leather is brought through a loop and fixedly attached to the ends of the hand-grip member, and a fabric piece of material is brought through the other side of the loop to form an anchoring portion for attachment to the luggage case.

Abstract: A substantial amount of liquid lubricant used in a cold strip rolling mill is prevented from passing between the area of the work roll necks and work roll bodies not in contact with a strip by locating in a strip guiding means on the entry side adjacent both edges of the strip, several zoned air nozzles which delivery a positive pressure to force the liquid away from this area, in a direction toward the center of the strip and rolls, and which nozzles are controlled according to the width of strip being rolled. The relatively small amount of liquid finding its way onto the delivery side is removed from the strip by providing in the strip guiding means both positive and negative air pressure means located above and below the strip, and negatively pressurized longitudinal enclosures located adjacent both edges of the strip and the said area.

Abstract: A rolling mill arrangement having at least one roll carrying a sleeve forming a cavity with the roll body near the two opposed ends of the roll.
