  • Patent number: 3956866
    Abstract: A packaging system for packaging articles in bag-like containers. An adjustable support disposed below a loading station receives the lower end of a container positioned in the loading station and articles loaded into the container. The support includes a pair of relatively movable members defining surfaces which converge toward each other to support the container when loaded.

  • Patent number: 3956903
    Abstract: A system for recovering and condensing vapors from a liquid process or storage tank in which a shell is connected to the tank for receiving the vapors from the tank, and a vortex tube is adapted to supply a stream of cold air into said shell. The cold air is passed in a heat exchange relation to the vapors in said shell to condense the vapors, and the condensed vapors are passed back to the tank.

  • Patent number: 3956904
    Abstract: A compressor-expander assembly for use in a refrigeration system which includes a housing defining compression and expansion chambers of generally cylindrical section arranged side by side. Compressor and expander rotors of cylindrical shape are journaled for rotation in the respective chambers. The rotor shaft is offset from the chamber axis so that the surface of each rotor extends closely adjacent to the wall of the chamber causing each chamber to have a convergent side and a divergent side. Equally spaced about the rotor periphery are a set of vanes having their outer edges extending into engagement with the walls of the respective chambers so as to define a series of compartments of changing volume. The compression chamber has an arcuate inlet port which extends over substantially the entire divergent side and a concentrated outlet port which is located near the end of the convergent side.

  • Patent number: 3956906
    Abstract: The panty portion of the panty hose is knit of stretch and spandex yarns to provide compressive force against the body of the wearer. The panty portion includes an attractive pattern of relatively opaque areas and open lace areas with alternate courses being knit of spandex yarn and intervening courses being knit of main and auxiliary stretch yarns. The spandex yarn is knit in every wale of the opaque areas and is selectively knit and tucked in the open lace areas. The main stretch yarn is knit in every wale of both the opaque and open lace areas while the auxiliary stretch yarn is knit in plated relationship with the main stretch yarn in the opaque areas and is floated in the open lace areas.

  • Patent number: 3956907
    Abstract: Apparatus for tensioning textile material as the material is knitted from a strand of yarn into an elongated sock by a circular knitting machine includes a first roller over which the sock is passed and a second roller which urges the sock into engagement with the first roller. The first roller has a left-hand helix on one half of its surface which advances from the center of the roller to the edge of the roller as the roller rotates, and has a right-hand helix on the other half which advances from the center of the roller to the opposite end of the roller as the roller rotates. These helixes hold the sock in alignment between the first and second rollers. The first roller is driven by a belt and pulley arrangement and the second roller is free-wheeling so that it is rotated by tangential force applied thereto through the sock.

  • Patent number: 3956908
    Abstract: A knitted sleeved garment is made from a blank comprising sleeves and body joined together on the knitting machine by sleeve and body shoulder portions knitted integral with one another and formed with wales of different lengths by taking successive needles out of action during knitting of the shoulder portions and reintroducing those needles in opposite sequence to cause the sleeves to lie at an angle to the body. The shoulder portions extend only part way from the arm pits of the blank to the neck and a shoulder region of the blank adjacent the neck is formed by extensions of the body shoulder portion and/or sleeve shoulder portions.

  • Patent number: 3956909
    Abstract: The body garment is of seamless knit and unitary construction and may comprise a panty or the body portion of tights or panty hose of the one-piece type. The body garment comprises a plurality of panels formed by reciprocal knitting which enables variations to be made in the size of different portions of the body garment according to the walewise and coursewise dimensions of the several panels. These panels comprise two elongated waist panels generally formed with tapered edges and separated by a crotch panel running generally perpendicular thereto. The last complete course on the leg portion of the body garment is parallelly interknitted with the adjacent courses on both the crotch and waist panel sections.
