A method, apparatus, and kit are provided for non-invasively freezing a content of a pipe. The method comprises the steps of applying a substantially continuous seal over an outside surface of a pipe at a location where a content of the pipe is to be frozen, covering a surface area of the pipe with a cover sheet in such a way that the substantially continuous seal separates the cover sheet from the surface area to define a cavity between the surface area and the cover sheet, and introducing a cryogenic fluid into the cavity to draw heat away from a content of the pipe, through the surface area. A periphery of the cavity is defined by the substantially continuous seal. The method advantageously provides an apparatus for freezing the content of the pipe. A kit can be used to assemble the apparatus. Advantageously, the method, apparatus 80, and kit provide a non-invasive way of freezing the pipe's content. There is no need to penetrate the wall of the pipe to insert any complex structures or mechanisms. Nor do the method, apparatus, and kit require multiple complex devices, each of which accommodates different diameters of pipe. The method, apparatus, and kit advantageously can be used at locations along the pipe where there are external obstructions 30. They also can be used in such a way that the escape of cryogenic fluids into the atmosphere is minimized, if not eliminated.

A composite cellulose fiber reinforced polyolefin is enclosed. The polyolefin is manufactured by a process that includes preparing and mixing a blend of molten polyolefin, a coloring concentrate and a coupling agent in a kneading extruder, preheating cellulose fibers in an enclosed cram feed and mixing the blend of polyolefin, preheated cellulose fibers and ozone gas in a ozone chamber to form a polyolefin and fiber matrix. The polyolefin and fiber matrix is then fed to a twin screw extruder where it is further heated, mixed and then conveyed to a die to extrude the mixer to a desired shape.

A golf club holder can be folded up to be carried in a golfer's pocket and can then be unfolded or extended so that its ground-piercing legs can be pushed into the ground. The golf club holder includes a clamp, having first and second clamping surfaces, at least one of which is movable relative to the other for clamping the golf club onto the golf club holder. The golf club holder is clamped onto the club and is then pushed into the ground simply by holding the grip of the club and pushing the club down until the head of the club rests on the ground. To remove the holder, the golfer simply pulls the club by its grip, pulling the holder out of the ground, and then removes the holder from the club. In this way, the golfer can keep a spare club handy without its grip getting wet and without having to bend down to pick up a club from the ground.

An arm and hand rest device for performing microsurgery, such as an eye operation, on a patient lying on an operating table, the device having a board placed on the operating table beneath the upper body portion of the patient so that the weight of the patient will hold the device firmly in place. Two tables are disposed at the head end of the board and each includes a platform on which the hands and arms are rested while the surgeon uses a scalpel or other instrument in performing the operation. The tables are spaced from one another to define the area in which the patient's head is placed for the operation, and the platforms are adjustable vertically and have projections at the top end extending toward one another.
摘要:
A method of manufacturing a pallet made of a composite cellulose fiber reinforced polyethylene is disclosed. The composite polyethylene is produced through a process which blends preheated cellulose fibers with molten polyethylene. The blend of polyethylene and fibers is combined with ozone gas to form a polyethylene and fiber matrix. The polyethylene and fiber matrix is then fed to an extruder where it is further mixed, heated and then extruded through one of a series of dies to create the components of the pallet. The pallet has excellent rigidity and is welded together by coating meeting surfaces with a bonding material of blended high density polyethylene and iron oxide, placing the pallet into an electromagnetic field, and energizing the pallet with electromagnetic field having a frequency between 1 megahertz and 100 megahertz, causing the bonding material to melt and fuse the meeting surfaces.

Scope cover apparatus includes a generally cylindrical element made of stretchable material with end pieces and with a relatively narrow and elongated opening through which a scope fits into the scope cover. The material out of which the scope cover is made is elastic enough to stretch to fit onto a scope and yet to substantially cover the scope when the scope cover is placed on the scope for maximum protection.

A new and improved smoker's utility apparatus includes a base assembly which has a longitudinal axis and a transverse axis. A plurality of wells are contained within the base assembly. The wells include first wells adapted to receive containers. The wells include second wells adapted to receive pipe tools, and the wells include a third well extending substantially an entire longitudinal dimension of the base assembly adapted to receive a plurality of loose items. A plurality of containers are adapted to be received into the first wells in the base assembly. A plurality of pipe tools are adapted to be received into the second wells in the base assembly. A rough-surfaced striking surface is supported by the base assembly for igniting nonsafety matches struck on the rough-surfaced striking surface. One of the containers received in the wells of the base assembly is an ash tray. The ash tray includes receiving areas adapted to receive a cigar or a cigarette. The ash tray includes a clamp assembly adapted to receive and support a pipe. The pipe clamp assembly is supported by a support column which is supported by a floor portion of the ash tray. The containers include air-tight containers. The air-tight containers include body portions and lid portions.
