Abstract: A method for the eradication of venous blemishes, such as venous "spiders," "sunbursts," telangiectases, venous plexi and groups of dilated venules consists of sclerotherapy employing at least a 20% saline solution with heparin added as a sclerosing agent. The afflicted venules are first partially emptied of blood by gravity and are then completely cleared by forcing small amounts of air through them before they are injected with the sclerosing solution. Chemical burns caused by the caustic effect of extravasated solution on surrounding tissues may be counteracted by injection of water or of a dilute solution of procaine hydrochloride (commonly known as Novocaine) in water.

Abstract: Rolling mills require uniform temperature control across the width of the sheet in order to roll a flat metal sheet of uniform gauge. This invention provides a rolling mill with spray nozzles that operate in groups to maintain substantially uniform temperature across the width of the sheet metal. Back pressure of the coolant within the cooling spray nozzle adjustment means obtains automatic control of individual nozzle adjustment to make the rate of flow of the coolant to the sheet metal workpiece always obtain substantially uniform temperature of the metal. In place of back pressure, other signal energy supplied to nozzle adjustment can be used. The nozzles are carried by spray boards that adjust to control the angle of impingement of the nozzle sprays against the sheet metal; and there is a novel construction for transmitting liquid between fixed passage to other passages in the angularly adjustable spray boards without the use of hoses.

Abstract: This invention is a coaxial cable with watertight compartments between the discs that hold a center conductor coaxial with a tubular outer conductor. The object of the invention is to obtain greater mechanical strength for the cable without undue increase in attenuation. Discs are connected with the center conductor by a chromate conversion coating on the copper of the center conductor; by a polyethylene tube hugging the center conductor; and by necked down regions of the center conductor. This latter construction makes the cable suitable for microwave transmission as well as TV signals. Disc bonding to the outer conductor utilizes coatings on the inside surface of the outer conductor.

Abstract: An improved method of making hard and semi-rigid book covers, and the product obtained, provides a multi-layer plastic book with any desired ratio of flexibility to stiffness in the different parts of the cover such as the front and back panels, the hinge lines and the backbone panel that connects the front and back panels. A first layer of plastic is cast or extruded on a casting paper or belt or other supporting surface, and additional plastic material is applied to the first layer over areas that will form the front and back panels, and to the backbone area if the desired cover is one that is to have a stiffened backbone panel. A second layer is applied under conditions that insure a highly effective bonding and freedom from distortion when a curing step is necessary. The operation is continuous and the laminate formed is severed into separate covers as it is delivered from the laminating operation.

Abstract: The telephone communication cable of this specification has a metal shield formed by bending a sheet of metal at one or both edges so that the portions of the sheet that are folded over one another form a shield of double thickness and the shield has one or both of its edges formed by a continuous extent of folded metal instead of a square edge or fluted edge with a burr along the side of the edge toward which the slitting instrument advanced to make the cut. Air spaces are prevented by filling any clearance between the folded areas of the shield with adhesive. The shield is applied as a D-Screen with the edges off the original strip on the curved part of the D-Screen and away from the group of pairs that are shielded by the D-Screen.

Abstract: In raster-scan of a given electronically imaged field, a predetermined digital value is assigned to each raster element. A raster element scanned for the first time, within the boundaries of an object to be evaluated, is projected in at least one preselected direction upon raster elements of consecutive raster lines, thereby changing its digital value in each consecutive line scan by one digit position until said predetermined value has become displaced to a preselected guide value. All raster elements which after scanning are associated with said preselected guide value define an object which is to be evaluated.

Abstract: This method of copper plating aluminum and aluminum alloy wire or strip applies an adherent and ductile plating while the wire is moving rapidly and continuously through the plating apparatus. An improved chemical zincating step followed by a copper pyrophosphate strike plating, within critical thickness limits, reduces the plating time and makes practical plating of the wire while moving at speeds of about 100 feet per minute or more in relation to the processing solution.

Abstract: For binding books with plastic covers, this invention cuts the covers from plastic stock such as calendered sheets or continuous webs; and the plastic is preferably one that can be cut from the stock with a die used with a high frequency electromagnetic field for softening the plastic. In the preferred method, a tear line is formed around the outline of the cover and the cover is torn from the sheet with a smooth tear. The leaves constituting the filler for the book are assembled, stabilized with adhesive and then trimmed before assembly with the cover. With plasticized covers, provision is made for preventing migration of the plasticizer into the adhesive with possible resulting loss of strength of the adhesive. By using electromagnetic adhesive to stabilize the filler, the adhesive can be activated by an alternating electromagnetic field when desired to secure the filler to the spine portion of the cover.

Abstract: A parison for blow molding is applied to a core rod by successive injection operations in different injection molds. The material for the first layer is injected into the end of the mold cavity remote from the neck portion of the core rod, in the usual manner. The second layer is injected into the second injection mold cavity adjacent to the neck of the core rod to flow over the first layer in a direction from the cooler part of the first layer toward the hotter part. The twolayer parison is then transferred to a blowing mold where it is blown in the usual way.

Abstract: This flyer bow is for a machine used for twisting together communication cable wires to make conductor pairs, or twisting together large numbers of wires. The bow has a recess into which the twisted wires can nest and be held by centrifugal force in a position away from the windage caused by the rapid rotation of the bow in an orbital path. This prevents a loop from forming in the twisted wires as sometimes occurs in machines where windage overcomes the centrifugal force and wire tension. This invention permits operation of twisting machines with lower wire tension.
