  • Patent number: 5090760
    Abstract: An assembly for flexibly securing the fuel filler pipe of a vehicle to the body of the vehicle. The assembly includes a flexible support member which is designed to provide a "break-away" connection to a housing which is attached rigidly to the body of the vehicle. Thus, in the event that the vehicle is involved in an accident, the filler pipe connector is permitted to move relative to the body thereby reducing the chance of breakage between the fuel filler pipe and the fuel tank of the vehicle. In addition a rigid connector plate is rigidly attached to the fuel filler pipe. This connector plate serves to connect the filler pipe to the flexible support member and in the event of an accident, it serves to protect the open end area of the filler pipe so as to reduce the chance of damage thereto, and also serves to lessen the change of damage or disengagement of a fuel cap attached to the filler pipe.

The clip is generally annular and in a first embodiment is preferably divided into four independently formed parts that transiently diverge when the base part of the manifold is driven into the clip and which regain their initial position of repose after the base has traveled therepast, capturing said base and preventing its retraction. Both the base and clip are provided with apertures or bores or cutaways that fill with flowable elastomeric material when the inflatable article is molded so that the manifold and clip become an integral part of the inflatable article when the elastomeric material hardens. In a second embodiment, the clip is integrally formed and is molded into capturing relation to the base.

  • Patent number: 4726527
    Abstract: A drip irrigation emitter which is constructed of a tubular housing within which is located an internal chamber. A pressurized source of water is to be supplied to the internal chamber which is divided into a plurality of valve chambers. Within each valve chamber is mounted a ball. The ball is to be movable due by the water pressure to engage a valve seat. Formed within the valve seat are a plurality of minute flow passages through which the water is to seep or trickle into a closed chamber with therebeing a separate closed chamber for each valve seat. The closed chambers are formed within a cover, a separate distribution conduit is connected to each closed chamber through which the water is conducted to be deposited at an exterior location. Each of the distribution conduits is passed through a separate opening formed within the cover. The cover is fixedly mounted onto the housing.

  • Patent number: 4613168
    Abstract: A strong joint for hoses for the cooling and crankcase ventilation systems of vehicles is made between a hose 1 and a branch by inserting the flared end 3 of a rigid cylindrical insert 4 into a hole 9 in the hose 1 to distort the margin around the hole. A second hose 6 is then positioned over the insert 4 so that its end abuts the margin of the hole and the joint is sealed and secured by an encapsulation which is vulcanized in situ.A curable polymeric liner 5 may be sandwiched between the insert 4 and the spout 6 and also vulcanized to act as a bond.The second hose may be omitted, leaving the insert as a projection to which a second hose may be fitted by other means.

  • Patent number: 4602658
    Abstract: A connector as disclosed for connecting fluid passages through a flexible eet material. The connector is appropriate for use in connecting the coolant lines of a personal cooling garment through a waterproof immersion suit or a chemical proof outer garment. The connector includes inside and outside connector blocks with matching faces that sandwich the sheet material between them. Fluid passages through the two blocks meet at respective ports in the matching faces and are joined by coupling sleeves extending through holes in the sheet material. O-rings around the ports seal the holes through the sheet material. A cap screw or the like secures the two blocks to one another. The connector is equipped with valve male fittings and male lock components of a standard connector system that is now used for personal cooling garments. This allows the use of the connector in conjunction with an existing and satisfactory "zero leak" connect and disconnect system.

  • Patent number: 4530525
    Abstract: A device and method for use in forming an access port, and also in forming a leakproof seal between a conduit (e.g., a catheter tube) and a thermoplastic film (e.g., the wall of an ostomy bag, wound cover pouch, or similar pouch). The device includes internal and external coupling rings adapted to be locked together with a collar of film material clamped therebetween. An elastomeric nipple has an enlarged proximal end portion similarly clamped between the coupling rings and contributes in forming fluid-tight seal between the parts. The method of use of the device is also disclosed, such method including the insertion of a piercing element into the opening of the internal ring to form a two-piece piercing assembly, followed by the step of utilizing that assembly to pierce a flexible plastic film and form a collar of plastic material about the outer surface of the internal ring.

  • Patent number: 4521041
    Abstract: A first pipe is connected to the wall of a container such as a larger pipe, tank or other vessel, wherein the transverse surface of one end of the first pipe is substantially flush with the inside surface of the portion of the wall of the container to which the first pipe is connected. The method for forming the pipe connection relies upon the plastic memory of the synthetic thermoplastic polymeric material from which the end portion of the first pipe and the portion of the wall of the container, to which the first pipe is to be connected, are formed. The diameter of a hole in the wall of the container is expanded in a cold condition in such a manner that the edges of the hole expand outwardly from the wall of the container while the diameter of the end portion of the first pipe is reduced in a cold condition such that the reduced diameter portion of the first pipe can be inserted into the expanded hole.

  • Patent number: 4364210
    Abstract: Penetrations or passageways through fire resistant walls, floors, partitions and ceilings are frequently necessary to provide for present or future pipes, cables or conduits. A device fixed to the walls of the penetration provides a barrier to prevent the passing of fire, heat, smoke and toxic gases, and water through the penetration under adverse conditions of fire or elevated temperatures. The device includes at least one end cap capable of providing a cold smoke seal. An intumescent material which in the event of excessive heat or fire, foams and expands to substantially fill the penetration, is provided. The device may include a laminated restraining layer to provide assurance that the char formed during the intumescent reaction to fire and heat, is generated so that the penetration cavity is optimally filled.

  • Patent number: 4335905
    Abstract: A tank installation comprising a tank having at least one flexible wall arranged to rest on a rigid apertured partition, which per se does not form part of the invention. A flexible duct is joined to said wall and is intended to pass through the aperture in the partition. One end of the duct is connected to the flexible wall of the tank by a folded-over portion located inside the tank, and the other end of the duct is arranged for connection to another device that is to be placed in communication with said tank.The other device may be a second tank which also comprises a flexible wall with a flexible duct substantially aligned with said flexible duct of said first tank, and the extremities of said two flexible ducts are joined to a rigid pipe. These two tanks may be adjacent, the flexible duct of said second tank being directed towards the inside of the second tank and the rigid pipe is located within the second tank.

  • Patent number: 4324424
    Abstract: An assembly for connecting a tubular conduit to an apertured wall of a non-metallic enclosure including a tubular insert seated in the aperture and a threaded, rotatable, hollow hub member arranged to be received by an externally projecting portion of the tubular insert. The closed end of the hub member adjacent the enclosure rests against a compressible resilient ring for sealing engagement and being further adopted for rotatable engagement with respect to the enclosure by means of an interposed washer made of a material having relatively low coefficient of friction with respect to the hub member. The components of the assembly are held together by means of a laterally extending lip formed at the distal end of the insert after assembly of the cooperating elements to the enclosure.
