Abstract: A corrugated pipe connection joint structure and method for connecting two sections of corrugated pipe. The joint structure includes opposing bell-formed ends with reduced corrugations, a connector insert including a gasket on either end and a push-ring. The gasket(s) form a seal sufficient to keep fluid inside the pipe, and to help keep the joint structure from separating under normal use.

The pressure relieving arch includes a first protective pipe sleeve in the shape of a hollow semi-circle having a first pair of mating edges; and a second protective pipe sleeve in the shape of a hollow semi-circle having a second pair of mating edges. The first pair of mating edges of the first protective pipe sleeve for mating and connecting with the second pair of mating edges of the second protective pipe sleeve for forming a hollow and cylindrically-shaped pressure relieving arch.

Abstract: A photographic mount. The mount includes a base member having a fold line defining a pair of blanks. The base member is made of a support layer and a polymer layer disposed thereon, preferably a low density polyethylene. The base member further includes a pair of spaced apertures which are disposed in overlapping registration when the base member is folded along the fold line. A locating frame is carried by one of the pair of blanks attached to the polymer layer, to form a frame about one of the pair of apertures.

Abstract: A magnetically receptive carrier plate 20 for a conventional shopping cart 10 is provided for the convenient in-store use of magnetic mount shopping aids such as a notepad/coupon holder 30, writing implement holder 60 or calculator 23. The magnetically receptive carrier plate 20 is rotatable around the handlebar 11 of a conventional shopping cart 10 and can present either magnetically receptive surface 20a or 20b to the shopper for the convenient magnetic mounting of portable notepad/coupon holder 30, pencil holder 60 or calculator 23. Supported on one side by the handlebar holder 21, the other end of the carrier plate rests on either the upper rear transverse rod 13 or the child seat upper transverse rod 14 of the cart 10. Additionally, the carrier plate can be rotated rearwardly over the handlebar 11 toward the shopper to hang downwardly in front of the shopper.

Abstract: In a door closer device which requires at least three switches consisting of a half door detection switch, a full lock (completely closing) detection switch and a switch for detecting the return to the initial position, the number of switches can be reduced. Two cam switch operating portions are formed on a cam plate fixedly secured to an output shaft of a motor. The motor is stopped by making use of one operating portion and the motor is rotated in a reverse direction by making use of the other operating portion.

Abstract: A spider for use in a compact universal joint, includes a spider body having a hollow cylindrical portion and two opposed tenons projecting radially outward from the hollow cylindrical portion along a common axis. The hollow cylindrical portion is adapted for installation of bearings therein for pivotal support of the cross body on a pin mounted in a first yoke of the universal joint, and the tenons are adapted for mounting within bearings in a second yoke thereof.

Abstract: An improved slide groove fixing device for use of curtains has a single-track slide body, a movable abutting seat, a transversely U-shaped clamping seat, a supporting spiral member, and an adjusting bolt.

Abstract: A water proof neoprene impregnated sheet material fabric support is formed into an hour-glass shape with two mirror image sections and is surrounded by a zipper which closes the support to form an inner pocket that is water impervious. Two right circular cylindrical cushions form pillow portions made of an inner core of foam rubber encased by an outer woven cotton layer that is mounted to the sections within the periphery thereof. The cushions compress when the pocket is closed forming a watertight pillow that is portable and easily opened for use. A carrying strap is attached to the support for carrying the zipped pillow.

Abstract: The invention relates to a joint arrangement for cardan waves adapted for the transmission of torque; with at least one joint fork; with journals borne in the fork eyes of the joint forks; the bearing arrangement of each journal comprises at least one radial bearing; to each bearing arrangement there is allocated a cover-form element subdividable into at least two partial zones of different dimensions, which cover-form element forms in the zone of at least one partial zone an axial stop for the seat of the inner ring of the radial bearing. The invention is characterized by the following feature: Means are provided which brace the cover-form element with respect to the journal, at least over a partial range of the other, second zone.

Abstract: An advertising display for mounting an advertisement on a supporting structure such as a billboard, the side of truck, or any other substantially planar surface. The advertising display includes an elastic display panel with four edges reinforced by elongate stays. A plurality of upper attachment fittings are spaced lengthwise along the top of the supporting structure. A corresponding plurality of lower attachment fittings are spaced lengthwise along the bottom of the supporting structure. Opposing forward and rear attachment fittings are spaced vertically along the supporting structure. A plurality of retaining clips are also provided each for attachment to the outer lips of the lower attachment fitting as well as the forward and rear attachment fittings for the purpose of retaining the edges of the stays therein, thereby holding the stays captive. The display panel can be tautly suspended over the surface of the supporting structure between the four attachment fittings.

Abstract: The inner peripheral wall of the sleeve has four longitudinal grooves each disposed between two adjacent races. The driver has the form of a cross with four arms disposed radially at right angles to one another and each serving as a pivot shaft for a corresponding equalizing lever. Each bipod has four radial lugs disposed at 45.degree. to the axis of the rollers carried by said bipod, and each lug has on its surface facing the driver a slot designed to receive an associated end of the corresponding equalizing lever.

Abstract: A connection tightness and swing angle adjustable pivot includes a rotary shaft, a stationary shaft having a slit end rotatably received in an end of the rotary shaft, and an adjusting bolt. The adjusting bolt is screwed into the slit end of the stationary shaft with a head portion located in the rotary shaft but accessible with a hand tool via openings formed on the rotary shaft. The adjusting bolt has a tapered portion contacting with another tapered surface around inner wall of the stationary shaft. When the adjusting bolt is turned at the head portion via the openings on the rotary shaft so that it is screwed further into the stationary shaft, its tapered surface tightly presses against the tapered surface in the stationary shaft to expand the slit end of the stationary shaft, so that the stationary shaft more tightly contacts with inner wall of the rotary shaft.

Abstract: A method for safe restraint of occupants in a crashing vehicle using safety belts, and a double tube frame construction vehicle seat. In a crash the kinetic energy of the occupant is restrained by the belt and by the cooperating resiliently deformable double tube frame construction in such a way that, at a moderate load, the upper portion of this double tube frame construction will move resiliently, but with a bigger load a permanent deformation will be the result. The device includes a seat frame with a seat portion and a back rest portion being made of a parallel tube frame having two tubes arranged above/under and forward/behind, at the seat portion and at the back rest portion respectively, up to a height at the breast of the occupant. The tubes are twisted above this height to a position side by side. Reinforcing, deformable form plates are rigidly arranged between the parallel tubes at least at the seat portion and at the lower portion of the back rest portion.
