Abstract: The body bulge controlling portion of the panty hose has elastic yarn incorporated therein to provide a medium amount of compressive force against the body of the wearer and is positioned between portions of the panty hose having a relatively great amount of compressive force and a relatively small amount of compressive force. The compressive force against the body is thereby varied in a stepped or gradual manner so as to eliminate or minimize the abrupt outward bulging of the underlying portion of the body of the wearer. In one embodiment of the panty hose, the body bulge controlling portion is positioned between a panty girdle portion with a great amount of compressive force and the sheer legs which include very little if any compressive force. In another embodiment, the bulge controlling portion is positioned between the elastic waistband and the upper portion of the panty of the panty hose.

Abstract: Apparatus for forming loops of strip material, with each loop comprising a length of the material having its ends secured together, comprising a sewing machine for stitching ends of the length of strip material together to form it into a closed loop, and nozzles for directing air under pressure at the material for intermittently feeding a length of the stip material from a supply. A guide is provided for guiding the leading end portion of the strip material as it is fed forward from the supply generally into the form of a U extending down on one side of the sewing machine and up on the other side of the sewing machine. A cutter is provided for cutting the strip material at the trailing end of the U-shaped leading end portion of the strip material to provide a generally U-shaped length of the material with the sides of the U-shaped length of material extending on opposite sides of the sewing machine.

Abstract: A tent comprising side walls which are inclined when the tent is erected, loops at the lower edges of the walls adapted to receive stakes driven into the ground, and a floor member of water impervious material comprising a floor panel adapted to lie on the ground when the tent is erected and sides extending up from the floor panel, the perimeter of the floor panel being spaced inwardly from the lower edges of the walls when the tent is erected, the sides of the floor member and the walls of the tent being sewn together at seams at the upper edge margins of the sides of the floor member, said seams being above the ground. Rings of elastic material are provided at the perimeter of the floor panel adapted to receive the stakes for holding the floor panel taut.

Abstract: A four-point suspension for a load comprising first, second, third and fourth supports for the load located at the corners of a quadrilateral and adapted to bear on a supporting surface for supporting the load above the surface at four points. Each support has an individual connection with the load for transmission of force from the load to the supporting surface and each connection permits relative up and down movement of the load and the respective support at the respective corner.

Abstract: Apparatus for feeding a web of material from a supply thereof through an inspection area and winding the web, comprising a frame, a supply roll on the frame, a mandrel for winding the web on the frame having a gripper for gripping a leading end portion of the web, a drive for rotating the mandrel for winding the web thereon and for feeding the web through the inspection area, a panel engageable with the leading end portion of the web for backing the web fed through the inspection area, a pivotal connection mounting the panel on the frame for movement between an operative position relative to the mandrel for starting the winding of the web and a retracted position away from the mandrel, the panel being engageable with the leading end portion of the web, and cylinder units attached to the panel for moving the panel between operative and retracted positions. The gripper comprises a series of holes in the periphery of the mandrel and a vacuum pump in communication with the holes for drawing air into the mandrel.

Abstract: A vehicle comprises a frame, wheel carriers spaced longitudinally of the frame, and wheels on the carriers. A suspension system supports the frame on the carriers with connections between the frame and the carriers allowing relative rocking movement of the frame and each carrier about an axis extending generally longitudinally and centrally of the vehicle. Linkages between the carriers on opposite sides of the axis each comprise bell cranks having a first arm interengageable with the respective carrier and a second arm, and a tension link interconnecting the second arms, adapted to effect relative rocking movement in one direction of one carrier and the frame on relative rocking movement of the other carrier and the frame in the opposite direction, and vice versa.

Abstract: The treatment of nylon fabric for wettability, with the treated fabric capable of withstanding a substantial number of launderings without undue loss of wettability, involving exhaustion of a condensation product of ethylene oxide with an aliphatic primary amine having between about 16 and about 18 carbon atoms in a ratio of about 16 moles ethylene oxide per mole of said primary amine, quaternized with methyl sulfate, onto the fabric under relatively intense agitation.

Abstract: A cover of flexible sheet material and a flexible resilient rib adapted to extend in arched configuration over a boat from adjacent one gunwale of the boat to the other for supporting the cover arched over the boat. The rib is secured to the cover with the cover extending down beyond the ends of the rib and then down on the sides of the boat for securement over the boat. The rib may be bent into various arched configurations depending on the beam of the boat, and then held in any of the arched configurations.

Abstract: The snag resistant leg portion of this hosiery article is knit of a composite self-crimping yarn including a series of mechanical crimps imparted thereto prior to knitting, and a series of crimps imparted to the composite yarn by development of the latent crimp in the composite yarn after knitting. The hosiery article knit of the composite self-comprising yarn having both types of crimp therein has much greater snag or pick resistance than either a hosiery article knit of the same type of composite yarn but including only the crimps imparted by development of the latent crimp in the yarn, or a hosiery article knit of yarn having mechanical crimp only. The knitting of a mechanically crimped composite yarn also produces a normal size greige hosiery article blank which may be processed in the usual manner to produce the finished hosiery article.

Abstract: A coating composition useful for imparting fire resistance and water-repellency to fabric comprises between about 5% and about 23% by weight of a liquid chlorinated paraffin, between about 20% and about 40% by weight of a resinous chlorinated paraffin, between about 4% and about 12% by weight of a copolymer of ethylene and vinyl acetate, between about 3% and about 18% by weight of a fire retardant, and up to about 15% by weight of an organic solvent. A novel water-repellent and fire resistant fabric material, and a method of preparing such material by coating tentage fabric with the composition of the invention are also disclosed.

Abstract: A tent comprising four walls and a peaked roof, the upper edges of the walls constituting eaves which generally form a rectangle when the tent is erected. The tent further comprises an external frame for holding the tent erect including a pair of eave frame members for attachment to two opposite eaves extending generally parallel to the two eaves on the outside thereof and a pair of poles, one for each of the eave frame members, for supporting the eave frame members to hold the tent erected. Each pole has means at its upper end for connection to the respective eave frame member generally at the center of length of the eave frame member. The external frame also has a ridge frame member extending generally centrally over the roof of the tent from one of the eave frame members to the other. The ridge frame member has means for connection of the center thereof to the peak of the roof.

Abstract: A tent comprising a bay extending from front to rear and wings extending laterally outwardly from opposite sides thereof, each wing having a front wall and a back wall, each wall of each wing comprising an outside screen and an inside closure flap adapted to be closed on the inside of the screen or opened for ventilation purposes, the closure flaps also being adapted to form partitions dividing the bay into individual chambers.
