PIPE FITTING INSTALLATION DEVICE
20190203867 · 2019-07-04 ·

A portable assembly for securing a plastic fitting to a plastic pipe by employing fusion or thermal sealing is disclosed. The assembly is secured to the outer circumference of a plastic pipe at a desired location. The assembly can be secured at any longitudinal and lateral position along a plastic pipe. A heater heats both the pipe and the fitting to the point where they begin to melt. The heater is then removed and the fitting is pressed onto the surface of the pipe, thus fusing the fitting to the pipe. After cooling, the assembly is removed and the surface of the pipe within the interior of the fitting is drilled or removed. This now enables fluid within the pipe to be sent to the fitting and onto distribution lines which are connected to the fitting.

PROTECTIVE TEXTILE SLEEVE WITH HOT MELT FIXATION, END FRAY PREVENTION LAYER AND METHODS OF CONSTRUCTION AND APPLICATION THEREOF
20190181626 · 2019-06-13 ·

A protective textile sleeve having enhanced end fray resistance and being adapted to be bonded to an elongate member extending therethrough, and method of construction thereof, are provided. The sleeve has a wall with a cavity bounded by an innermost surface extending between opposite open ends. A first material, including a hot melt adhesive material, facilitating bonding the wall to an outer surface of an elongate member extending therethrough, is bonded to the wall immediately adjacent the opposite ends, and a second material, facilitating prevention of end fray of the wall ends, including an elastomeric material is bonded to the wall immediately adjacent the opposite ends.

IV MEMBRANE ATTACHMENT SYSTEMS AND METHODS

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.

Fusible Size-On-Size Or Reduced Branch Fitting For Use With Polyethylene Pipe
20190137024 · 2019-05-09 ·

A fusible fitting of this disclosure includes a saddle having a radially extending branch with a closed bottom end. The closed bottom end forms a portion of the saddle and contains some of the fusion wires that run through the saddle. After the fitting is fused to a pipe, the closed bottom end may be tapped through, with that portion of the fusion wires being removed along with the coupon. Because of this configuration, the branch may be a size-on-size or near size-on-size branch. For example, the radially extending branch may have an inside diameter in a range of greater than 75% of an inside diameter of the pipe to 100% of the inside diameter of the pipe plus one wall thickness of the pipe.

STABILIZER BUSHING

A stabilizer bushing installed on a stabilizer bar is made of two divided parts of rubber or the like to prevent or decrease generation of a gap in a bonding surface. The stabilizer bushing installed on an outer periphery of the stabilizer bar by adhesion includes divided rubber bushings of an upper rubber bushing and a lower rubber bushing. Before adhesion, both end portions of the upper and lower rubber bushings, respectively, in a circumferential direction are tapered so that an overlapping amount between the upper and lower rubber bushings increases toward the outer periphery side of the bushings. After adhesion, a bonding surface is bonded by pressure

A stabilizer manufacturing apparatus is adapted to bond a rubber bush, which is a bush made of rubber disposed between a stabilizer and a vehicle body, to a rubber bush bonding location where an adhesive layer of the stabilizer is formed. The stabilizer manufacturing apparatus is provided with: a curing furnace for heating the stabilizer, which is conveyed by a manufacturing line conveying unit and has the rubber bush bonding location with which the rubber bush is press-contacted, and performing the bonding; a heat source device that heats air; a blower device that sends the air heated by the heat source device as hot air; and a plurality of nozzles that are disposed along the manufacturing line conveying unit in the curing furnace and blow the hot air against, at a near position from, a location in the vicinity of the rubber bush bonding location of the stabilizer.

Catheter shaft having high strength and flexibility

Elongated shaft for a catheter including a single layer biaxially oriented nonporous thermoplastic polymer tubular member having a Shore durometer hardness of less than about 75D is provided. Elongated shaft for a catheter prepared by a process is also provided.

Penetration fitting
10240695 · 2019-03-26 · ·

Disclosed is an apparatus, a kit, and a method for repairing a sump wall pipe fitting. The apparatus may comprise first and second fitting halves for repairing a penetration fitting for a sump wall, the fitting halves having a semi-annular flange with a seal plate adapted to be sealed to the sump wall; at least one semi-cylindrical cuff that extends axially outward from surface of the semi-annular flange opposite the seal plate; and a semi-annular rib that extends radially inward from the semi-annular flange spaced at a distance between the seal plate and a rim of the at least one semi-cylindrical cuff. A dispensed bonder may also be included.

REINFORCED THERMOPLASTIC DUCT
20190078705 · 2019-03-14 ·

A reinforced duct system includes at least a first thermoplastic duct section and a stiffening ring affixed to the first thermoplastic duct section. The stiffening ring includes first and second thermoplastic core rings, an inner reinforcement strip adhered to and spanning adjacent interior surfaces of the first and second core rings, an outer reinforcement strip adhered to and spanning adjacent exterior surface of the first and second core rings, and a flat reinforcement ring interposed between the first and second core rings.
