Abstract: An extrusion pulling apparatus including an extrusion run-out table and an extrusion puller which is mounted for reciprocal movement along the run-out table. The extrusion puller has an upper jaw mounted for vertical reciprocal movement between clamping and release positions on a support frame and a lower jaw mounted for reciprocal lateral movement between clamping and release positions also on the support frame. The lower jaw is also mounted for vertical movement with respect to the support frame. A stripper finger is mounted on the puller adjacent the upper and lower jaws when the jaws are in the clamping position and is movable laterally to push extrusions toward a cooling table when the lower jaw moves in an opposite direction to strip the extrusions from the lower jaw and to push one end of the extrusions from the extrusion line.

Abstract: A flap is hinged on a container closure to swing between open and closed positions relative to a dispensing opening in the closure. When the flap is closed, upstanding ribs shield the free edge of the flap. A lift tab projects outwardly from the free edge of the flap and extends between the ribs to facilitate swinging of the flap to its open position. The flap is held releasably in its closed position by virtue of the ends of the ribs engaging the side edges of the tab with a snap fit and also by virtue of straight sections of the ribs engaging straight sections on the free edge of the flap with a snap fit at areas located adjacent the tab.

Abstract: A temperature controlled probe assembly (58) for measuring log temperatures in a furnace (10) for heating metal logs (20) includes a carriage (88) selectively movable by a pneumatically controlled air cylinder (64). The carriage (88) includes a barrel (92) having an air chamber (102), a pair of thermocouple probe rods (40, 42) extending through the barrel (92), and cooling air channels (126) opening into the air chamber (102) for supplying air to cool the probes (40, 42). Another thermocouple (94) measures the temperature of the environment surrounding the thermocouple probe rods (40, 42) and a cooling air regulator (160) is selectively actuated when the temperature of the probe environment is greater than a predetermined temperature. The regulator (160) varies the amount of cooling air supplied to the probe rods (40, 42) in accordance with the amount of combustion air being used by the furnace (10).

Abstract: A traveller for use in a textile spinning and twisting machine, includes a substantially C-shaped member adapted to engage and travel about a ring of the machine, the member having an outer surface and an inner surface constituting a yarn guide path on which yarn travels, the yarn guide path on the inner surface being free of any mold parting line, the traveller being formed in a mold and the yarn guide path on the inner surface being formed by a groove in an ejector pin of the mold.

Abstract: A conductive yarn includes a continuous non-conductive carrier thread having a relatively low modulus of elasticity; a continuous metal thread; and the carrier thread being wrapped around the metal thread. A process for making such conductive yarn includes the steps of pulling the continuous metal thread off a first package; pulling the continuous carrier thread off a second package; applying a relatively high tension to the carrier thread with respect to the tension on the metal thread as both threads are being pulled off their respective packages; and wrapping the tensioned carrier thread around the pulled metal thread. Apparatus for performing the method is also provided.

Abstract: An extrusion run-out table for aluminum extrusions and the like has an extrusion support table for supporting extruded profiles as they are extruded from an extrusion press along an extrusion path and a conveyor for moving the extruded shapes from the extrusion support table to a cooling area and to a further processing area. The extrusion support table includes a set of elongated heat-resistant bars mounted perpendicular to the extrusion path, with the bars extending laterally of the extrusion path into the cooling area a distance sufficient to position one or more of the extended shapes in laterally spaced relationship to the extrusion path. The extruded shapes are cooled through an air manifold above the extrusion path and through a series of air jet nozzles which project cooling air against the extruded shapes as they are extruded.

Abstract: A method and apparatus for heating metal logs of a predetermined length in which the logs are cut into billets for an extrusion press. A furnace has an elongated heating chamber with an entrance opening and an exit opening. A pusher table is mounted adjacent the entrance opening of the furnace and a conveyor extends along the pusher table, through the entrance opening of the furnace, through the furnace heating chamber and through the exit opening thereof. A log dispenser is mounted adjacent the pusher table for dispensing logs seriatim onto the conveyor at the pusher table. An insert log has a length substantially less than the given length of the logs in the log train and is selectively positioned in the log train between the pusher and the lagging log in the log train to increase the effective length of the log train prior to adding a new log to the log train.

Abstract: An apparatus for dispensing essentially dry powder onto a surface to be cleaned such as a carpet. The apparatus comprises a hopper for holding essentially dry powder, a cylindrical applicator, rotatably carried by the hopper and mounted such that one portion of the applicator is in contact with the carpet to be cleaned and the other portion is in communication with the inside of the hopper. A transport cover encloses the applicator when the apparatus is not in use. A hopper cover and sealing means maintains the moisture content of material inside the hopper.

Abstract: An assembly for providing a visually discernible indicator and a bar code in association with goods to be sold, includes a tray having opposing side walls and a front panel containing the bar code in association with the goods; first and second clips secured to the opposing side walls, respectively, and each having a flange having an aperture therein; and an indicator panel containing the visually discernible indicator and including opposite tabs pivotally mounted within the first and second apertures so as to pivotally mount the indicator panel between a first position in covering relation to the front panel, and thereby in covering relation to the bar codes, and a second position exposing the front panel and bar codes.

Abstract: A temperature control system (50) for use in a furnace (10) for heating metal logs (13) as the logs (13) move through a furnace heating chamber (12) includes thermocouples (52a-52e) adapted to sense log temperatures by direct contact during intermittent time intervals when the logs (13) are stationary. Radiation sensors (64a-64 e) continuously sense radiant energy emitted from the logs (13) and a temperature compensation circuit (62) compares signals representative of log temperatures as measured by thermocouples (52a-52e) and the radition sensors (64a-64e). The difference between the signals is utilized during time intervals when the logs (13) are moving as a compensation factor for the continuous signals representative of log temperatures based on sensed radiation. The compensated signals and signals representative of desired set point temperatures are applied to log temperature controllers (80a-80e) to regulate the thermal energy applied to the logs (13).
