Abstract: A shielding bladder for the venting arrangement of a linear actuator having a housing, a reciprocable member disposed therein for linear reciprocable movement therethrough, and a venting arrangement in the housing for communicative flow of ambient air into and out of the housing during operation. The bladder is a sleeve sealably affixed exteriorly to the housing enclosing the venting arrangement and defining a chamber between the sleeve and housing that contains a volume of air for contractionally expelling the air into the housing in response to increases in its volumetric capacity resulting upon outward reciprocation of the reciprocating member and expansionally receiving air from the housing in response to decreases in its volumetric capacity upon inward reciprocation of the reciprocating member.

Abstract: A control system for use in textile processing equipment including a card and a chute feed delivering a batt of fiber thereto. The operating speed of the card is sensed to generate a signal that is used to drive the motor for the oscillating densification plate and the feed roll of the chute feed at speeds having a predetermined ratio of the operating speed of the card. The weight of the batt formed by the chute feed is sensed and a signal is generated in proportion to the sensed weight, and this signal is used to override the primary drive for the oscillating plate and thereby vary the ratio between the operating speed of the card and speed of oscillation of the plate. The chute feed includes a device for sensing the level of accumulated fiber in the chute feed, and this device generates a signal that is utilized to override the primary drive for the feed roll of the chute feed and thereby vary the ratio between the operating speed of the card and the speed of such feed roll.

Abstract: Bed frame members are provided for quick, snap-together, interlocking assembly for preventing relative rectilinear motion between members without loose or screwthread parts. One member has a first slot with an enlarged retaining portion and a mating member has a projection thereon for entrance into the slot. The projection carries a Belleville washer having its conical convex face disposed for engagement with the slot for compression as the projection moves thereinto and for retaining engagement with the periphery of the enlarged retaining portion of the slot when the projection has been fully inserted in the slot. A second slot in one member has a portion disposed at a substantial angle to the first slot and receives a second projection disposed on the other member.

Abstract: An underground duct is connected to other ductwork and controls associated with a building for automatically selectively passing outdoor air through the underground duct to the normally outdoor coils of a heat pump, recirculating air through the underground duct to the heat pump outdoor coils and back through the underground duct, and passing outdoor air directly to the heat pump outdoor coils and also passing outdoor air through the underground duct to recondition it, in order to achieve optimum heat pump efficiency for selectively heating and cooling the building. Alternatively, air from the underground duct or from outdoors is selectively passed directly into the building for optimum cooling thereof while a dehumidifier is used to remove latent heat from the air; and other heat sources may be used with direct recirculation of air through the building and addition of a portion of tempered air from the underground duct for slightly pressurizing the building interior with heated air.

Abstract: Apparatus for removing fiber portions from a selected plurality of bales and delivering the fiber to a receiver, such apparatus including a head that is lowered into contact with the top surface of such bales to grasp fibers therefrom. A control system is provided which generates a signal when the head has traveled a predetermined vertical distance toward a bale, and the signal is used to vary the sequence of pick-up or the amount of fiber picked up, from the plurality of bales to assure that the plurality of bales are maintained at substantially even heights during the sequential pick-up of fiber therefrom.

Abstract: A spring-loaded cartridge or capsule forms a connecting link for inclusion in the accelerator-throttle linkage of an internal combustion engine to convert such linkage to a changeable length linkage which permits an overriding governing action to close the throttle against the action of the accelerator without significant effect on the operation or feel of the accelerator. The operation or feel of the accelerator is not affected because the spring-loading of the cartridge is only slightly stronger than the normal throttle-closing spring which constantly urges the throttle toward its closed position.

Abstract: For use in textile processing, equipment such as jet dyeing machines, a fixed cloth tube for transporting cloth from the jet to the cloth storage compartment, such cloth tube having an exit end portion which is substantially greater in cross-sectional area than the portion extending from the jet, whereby the cloth leaving the cloth tube is permitted to assume a more open condition and whereby the velocity of the liquid flowing with the cloth is reduced as it leaves the cloth tube. A pair of cloth directing liquid jets are disposed oppositely in the exit end of the cloth tube, and a control system is provided for alternately admitting fluid to such cloth directing jets at predetermined time intervals to impose a sinuous path of movement on the cloth as it leaves the cloth tube and thereby provide an orderly and even distribution of the cloth within the cloth storage compartment.

Abstract: A textile yarn winding machine and method for winding yarn utilizing a rotatable package supporting spindle, two continuous belts movable oppositely along two respective traversal spans for traversingly moving yarn longitudinally along the package, and rotating yarn engaging fingers adjacent opposite ends of the package for positively transferring the yarn between the belts at the package ends. The belt traversal spans extend in crossing relationship from respectively opposite yarn engaging locations closely adjacent opposite ends of the package to respectively opposite disengaging locations spaced from the other package end to effect quick yarn reversals. The yarn engaging fingers move in circular reversal paths to positively engage the yarn at the disengaging locations of the spans, disengage it from the belt guiding it, and move it to the engaging location of the other belt.

Abstract: An improved method and apparatus for wet processing an endless rope of material wherein a modified J-box arrangement is provided for storing an accumulation of rope in a treating bath and a combined overflow chamber and liquid jet assembly is provided for circulating the rope to and from the bath in an entraining liquid stream. The storage arrangement includes a partially perforate outer wall and an imperforate partial inner wall spaced inwardly therefrom forming a confinement area therebetween for rope and liquid returning from the circulatory system. The confinement is sufficient to maintain therein a column of the returning liquid extending above the level of the bath whereby gravitational forces acting thereon hydraulically move the rope accumulation through the bath, the rope in the confinement being released to expand as it moves past the terminating end of the inner wall whereby movement of the rope through the bath is enhanced.

Abstract: A controller for the power supply system of a building structure divided into multiple zones provides a time-programmer and a load shedder for controlling the availability of separate heating, ventilation, and air-conditioning apparatus for individual zones and the separate apparatus associated with the building and includes switches for overriding the time programmer to allow selected apparatus to operate at will for a short period. The controller includes thermostats monitoring the temperature in the zones and operating the HVAC apparatus during certain temperature conditions, a meter for displaying the monitored temperature, and switches for selectively disconnecting the thermostats from the respective zone apparatus and connecting them to the meter while simultaneously connecting a dummy resistor to the respective zone apparatus in lieu of the thermostat.

Abstract: A multi-spindle double twist twisting machine having a belt drive assembly, a spindle frame formed to enclose the belt drive assembly, and traversing rod reciprocating means. The machine may be a horizontal spindle machine with two rows of spindles on each side. A beam mounted independently of the spindle frame extends along each side between rows and supports a drive belt for tangential driving contact with spindle whorls. The belts are commonly driven and reversing rolls are associated with one belt so that it travels opposite the other belt, and compensating rolls are associated with the other belt so that the belts may be of the same length. The spindle frame has two spaced support plates laterally outward of the belt drive assemblies and two cover plates secured to and extending between flanges on the support plates to form an enclosure for the belt drive assembly.
