Abstract: A gas flushing device for a blowpipe of a degassing vessel, the blowpipe being cladded with a fire resistant material. The gas flushing device has a plurality of channels which are distributed around the circumference of the blowpipe and pass through the fire resistant cladding radially in relation to the central longitudinal axis of the blowpipe and can be connected on the outside to at least one gas feed pipe. The channels are between 0.5 and 2 mm in diameter, are spaced at intervals of less than 10 mm and can be pressurized in such a way that the gas on entering the blowpipe rises in the immediate vicinity of the blowpipe inner wall.

Abstract: A method of preventing the inserting of a wrong flowmeter tube into an anesthesia machine comprises the steps of forming a selected number of longitudinal ridges at selected places on the inside surface of an upper portion of a flowmeter tube, attempting to insert the upper end portion into a socket pin mounted on the housing of a anesthesia machine, seating the tube on the socket pin if the socket pin exterior surface has grooves corresponding to the number and placement of ridges on the flowmeter tube, and rejecting the tube by the socket pin if the socket pin exterior surface does not have grooves corresponding to the number and placement of the ridges on the flowmeter tube, since the lack of said correspondences indicates that the tube is the wrong tube for the socket pin.
Abstract: A method for representing optically a fabric consisting of warp and weft threads and with a pattern. To optically represent the fabric, the pattern is acquired by scanning from a model, or from an existing data carrier, or represented directly on a computer display. A crossing scheme is then assigned to the warp and weft threads. The course of the warp and weft threads is then determined by varying at least one of any parameters specific for the thread, such as the number of color components of a single thread and their distribution, the construction of the thread's surface or the material of the thread and by varying at least one of any parameter specific for the fabric, such as the closeness of the warp and weft threads, the advance of material in weaving, the sequence of the warp threads or the control functions for a weaving machine.
Abstract: A bag suitable for use in microwave cooking is constructed of an elongated tube of flexible material closed at one end by means of a cold seal closure and having a heat seal adhesive deposit applied to the other end thereof for use in closing the bag after filling thereof; and methods of making the same are described, including the making of a roll from which said bags can be made.
Abstract: A spigot actuator assembly for dispensing liquid from a spigot mounted on a projecting spout of a bag-in-box container for operating a dispensing lever on the spigot to move the dispensing lever from a horizontal closed position to an upwardly projecting open position for dispensing the liquid from the container, and for quickly replacing the container when desired. A method of using the spigot actuator assembly including snapping the spigot actuator assembly onto the spout, pushing down on a lever of the spigot actuating assembly for dispensing the liquid, releasing the actuator assembly to automatically close the spout, and snapping off the actuator assembly from the spout when it is desired to remove the container, and snapping a replacement container onto the actuator assembly.

Abstract: A lightweight waterproof pouch for carrying personal objects such as cash, a watch, credit cards, a wallet, and the like in a wet environment and for keeping those objects safe and dry comprises an outer enclosure formed of flexible material, a removable, resealable, waterproof inner pouch liner for insertion into the outer enclosure, and a strap attached to the outer enclosure for holding the pouch around a wearer's body. The inner pouch liner forms a watertight compartment when closed for keeping the personal objects dry.
Abstract: Aerator with a basic body (10) that can be connected to an air feed (50) pipe and with a diaphragm (20), which can be attached to the basic body (10) and whose edge (20r) can be fixed to the circumferentail surface (10r) of the basic body (10) by a static fastening part (30) for the diaphragm (20), which fastening part is designed such that it surrounds the edge (20r) of the diaphragm (20) in a positive-locking manner and can be fixed itself to the basic body (10) wherein the basic body (10) has, on its side facing a way from the said diaphragm (20), a centrally arranged air inlet area (12, 14), on which the fastening part (30) can be placed with a corresponding connection part (36).
Abstract: A thermoplastic splinting material with a uniform skin contacting layer of silicone elastomer which accurately contours complex anatomical geometries and is suitable for use in the treatment of dermatologic scars. The product is manufactured in sheet form and may be custom shaped to fit the unique contours of an individual patient by a technician at the clinical site.
Abstract: An adjustable golf club having means for adjusting the balance of the club and means for adjusting the alignment angle of the club. A club head is attached to the connection end of the shaft by connecting means at a connection point along the heel-to-toe axis and at a line-of-play alignment angle and a heel-to-toe alignment angle. The connecting means includes a slide fixed to the connection end of the shaft and a socket in the top portion of the club head. The balance of the club can be adjusted by linearly moving the slide along the heel-to-toe axis in the socket. The line-of-play alignment angle of the shaft can be adjusted by rotatably moving the slide in the socket. After the club is adjusted, the slide is secured in the socket by locking means to prevent the club from deviating from the desired adjusted configuration during play. A method of putting a golf ball with the above-provided adjustable putter. The adjustable putter is provided to the golfer.
