Disclosed are a method and apparatus for laying down, abandoning and/or recovering a pipe on the sea floor. During lay-down and abandonment, the pipe is lowered by a high capacity winch to an intermediate depth, at which the loading exerted by the pipe has dropped to within the rated capacity of a low capacity winch, to which the loading is then transferred. The high capacity winch line is then recovered to the attendant vessel and the pipe lowered to the sea floor using the low capacity winch. Pipe recovery is essentially a reversal of the above procedure. In this way, the length of the line of the high capacity winch is considerably reduced, which reduces the winch size and hence cost.

An arrangement is provided for providing redundancy in a vehicle electrical control system, including a plurality of electronic control units connected to each other through a first data bus, and where each electronic control unit is connected to one or more I/O-units through a separate second data bus, where each second data bus is provided with a separate transceiver which allows communication between an electronic control unit and an I/O-unit, and where the arrangement includes a programmable switch arranged between the electronic control units and the transceivers, where the programmable switch is adapted to interconnect each transceiver with a selected electronic control unit. A transceiver may be reconnected to a new ECU in an easy way, when the ECU to which the transceiver was originally connected to breaks down, which allows the new ECU to access the I/O-units of the broken ECU and which in turn provides an effective redundancy for the electrical control system.

A mud flap holder assembly includes a mud flap support clip bifurcated at one of the ends thereof to define an open ended variable width slot. The mud flap is held in position by a bolt positioned in the slot with portions of the support clip defining the slot forming a detent frictionally releasably engaging the flap.

A lift-out device for attachment to a pitless adapter in a water well assembly for use when servicing well pumps including a light source mounted near the lower end of the lift-out device for illuminating the interior of a well casing to facilitate attachment of the device to a pitless adapter. Apertures are located in the side of the tubular pipe member adjacent the light source, and a socket for electrically connecting said light source to an external power source such as a rechargeable battery pack is preferably mounted in the handle of the device. The illumination device is preferably cushioned in order to prevent breakage during use and storage.

An eyeglass frame having selectively interchangeable temples has a conventional frame front, combined with specially-designed hinges and the temples. Each temple has a longitudinal cavity of generally rectangular cross section, at the hinge end thereof, that is in communication with a rectangular aperture that opens to the inner surface of the temple. Each temple is attached to a frame front end piece via an interconnection clip having a single loop that is sandwiched between two loops that are unitary with the frame front, and with the three loops being held together with a pivot screw, thereby forming a butt hinge. Each interconnection clip incorporates a single-barb spring clip that slides into the longitudinal cavity of a temple. The barb locks against a forward edge of the rectangular aperture. By depressing the barb with a finger, the temple and the interconnection clip can be pulled apart.

A belt for power transmission and for conveying elements is provided wherein the belt comprises a top layer attached to the top surface of the belt. The top layer provides a generally smooth top surface for the belt. The belt preferably is a link belt and the top surface of the belt comprises a bonding layer for adhering the top layer to the belt. The bonding layer may be a thermoplastic urethane that is heat fusible with the compressible layer to adhere the compressible layer to the belt. A method is also provide in which a top layer is adhered to a link belt and the top layer is then severed into a plurality of separate elements.

Provided are an adhesive composition suitable for a hot-melt adhesive which has a low tack and which after adhering to an adherend and through heat treatment comes to have sufficient adhesive force; and an adhesive product using the adhesive composition. The hot-melt adhesive composition includes an acrylic block copolymer (I) having at least one polymer block (A) including methacrylic acid ester units and at least one polymer block (B) including acrylic acid ester units, wherein the acrylic acid ester units constituting the polymer block (B) contain an acrylic acid ester (1) represented by CH₂═CH—COOR¹ (1) (wherein R¹ is an organic group having 1 to 3 carbon atoms) and an acrylic acid ester (2) represented by CH₂═CH—COOR² (2) (wherein R² is an organic group having 4 to 12 carbon atoms), and a mass ratio (1)/(2) of the acrylic acid ester (1) to the acrylic acid ester (2) is 90/10 to 25/75.

The invention discloses a yarn breakage retracting device for facilitatingbroken end connecting, and relates to the technical field of spinning machinery. The device comprises a base, a fixed seat isfixedly connected to the surface of the base, a standing column is fixedly connected to the surface of the fixed seat, upper retracting devices are fixedly connected on both sides of the standing column,lower retracting devicesare fixedly connected on both sides of the fixed seat, the inner surfaces of the upper retracting device and the lower retracting device are fixedly connected with retracting motors, the ends of the output shafts of the retracting motorsare fixedly connected with rotating rods, a plurality of lanyards are fixedly connected to the circumferential side surfaces of the rotating rods, hooksare fixedly connected with the ends of the lanyards, and the inner surfaces of the upper retracting device and the lower retracting device are rotatably connected with a plurality of rolling rods. Through the cooperationof the upper retracting device and the lower retracting device, the length of a fold line inside the device is increased through the hooks, so that a broken end ofa yarn is retracted toward the device, the broken end of the yarn can be quickly found, and the device has the advantage of facilitating the yarn broken end connecting.

The invention provides a self-power-off explosion-proof lamp with a high-temperature protection function, which comprises a lamp body, wherein the lamp body comprises a shell, an LED lamp panel arranged in the shell and a light-transmitting cover positioned at the light-emitting end of the LED lamp panel, and a power line is arranged at the top of the lamp body; a first radiator mounted on the rear surface of the LED lamp panel in an attached manner and used for absorbing heat on the LED lamp panel and radiating the heat; and an electric connector assembly used for connecting the power line and the LED lamp panel, wherein the electric connector assembly internally comprises a connecting mechanism with a heat collecting function, and when heat absorbed by the connecting mechanism exceeds a threshold value, expansion is generated, and connection between the power line and the LED lamp panel is cut off.
