Abstract: The float of this disclosure is used with a fishing line to support the bait at any desired depth below the surface of the water. When the fisherman swings his rod to cast the bait and float, they are close together for casting, but the float is constructed to permit the bait to move downward to a predetermined depth after the float strikes the water. When a fish is caught, the bait and fish are brought close to the float during the first part of the reeling-in of the line, so that the fish can be netted, if desired.

Abstract: This is a burglar-proof door for apartments or houses and it is held closed by bolts extending from within the door and into sockets in the frame that surrounds the door. The door has hinges, but in the preferred construction there are four bolts, one on each edge of the door so that the door cannot be opened by removal of the pins from the hinges. An electric motor operates, when a magnetically-coded card is inserted in a slot in the outside of the door, to lock or unlock the door when a handle is turned one way or the other. When there is a serious fire in the apartment or the house, a thermostat causes the door to unlock automatically.

Abstract: This beer-dispensing apparatus has a keg fitting with a single valve in the keg that is operated by an annular probe in a probe fitting to control the flow of the beer from the keg and the flow of gas into the keg. Both gas flow and beer flow are shut off automatically when the probe moves upward in the probe fitting. A conventional bayonet connection is used to connect the probe fitting to the keg; but a single handle, operated sequentially, connects the probe fitting to the keg and then opens the keg valve by further movement of the handle in the same direction.

Abstract: This blow molding machine overcomes the tendency of the parison to sag toward the bottom side of the core or for air currents to unevenly cool the parison, while at the same time allowing the parison to be cooled from the core side and then outside to the desirable orienting temperature, so that at the subsequent blow, or stretch-blow station, a bi-axially oriented container is produced having uniform wall distribution. As a means of intensifying the cooling on the outside, in order to speed up the operation, provisions are made to enclose the parison with an open end cylinder having means of introducing a flow of air in a tangential manner so that it circulates around the parison as the parison is rotated.

Abstract: This improved gland assembly is primarily for use with mineral insulated cables. The same gland body and lock nut is used for cables regardless of the cable diameter. The dimensions of the compression ring are the same, except for the ring bore, which matches the diameter of the cable. The lock nut bottoms on a shoulder to prevent overtightening of the nut and risk of fracturing the sheath of the cable.

Abstract: The subject invention relates to a new connector assembly design for making a low resistance, stable electrical connection to a plastic coated aluminum shield adhering to and underlying polyethylene jacket of telephone cables. When the connector in accordance with the invention is applied across the composite sheath, it eliminates the creep strain exhibited by the polyethylene jacket and aluminum shield and results in a stable low resistance electrical connection, which is essential for noise-free operation of the cable and good lightning protection of enclosed telephone circuits.

Abstract: This invention is an improved connection for splicing or terminating coaxial cables. The connection of this invention maintains substantially the same ratio of outer conductor inside diameter to inner conductor outside diameter as in the rest of the cable, and thus avoids impairment of signals transmitted by the coaxial cable. The splices prevent moisture from entering the cable when used underground; and the splices are strong enough to permit the cable to be plowed in with no fear of splice hang-up in the plow guides.

Abstract: This safety device has a delivery outlet and a pressure-relief valve for venting gas from a source of gas when the gas pressure rises above a predetermined maximum. A delivery line supplies gas from the source to a place of use, and there is a delivery line shut-off valve which shuts off flow to the place of use whenever the relief valve opens by a substantial distance from its seat. This prevents piping and hoses communicating with the delivery line from being subjected to excess pressure in the event that pressure rises faster than the relief valve can vent the excess pressure.

Abstract: This invention is an improved apparatus and method for making fiber optic communication cables by cutting accurate helical grooves in a layer of insulation surrounding the surface of a strength member, and inserting the fiberglass conductors into the grooves with fillers and spacers around and between the glass conductors to protect them from damage. Helically wrapped binders and heat barrier tapes may be wrapped over the assembly with any additional binder threads or tapes as may be necessary to hold the heat barrier in place.

Abstract: This package has a main panel with a plurality of sockets formed by displacing material of the panel in a direction to form sockets with closed ends within the package and the sockets opening through the bottom of the package. A thin and easily tearable film is adhered to the bottom of the package in position to close the lower ends of the sockets so that products do not fall out. The sockets can be collapsed by finger pressure against the upper ends of the sockets, and a pill pushed from a collapsed socket tears the film as it is pushed out. The package is made child-proof by adhering a strong film over the bottom of the thin film, and this strong tough film can be peeled off when a pill is to be removed from the package by an adult. A cover hinges over one end of the main panel and covers the closed ends of the sockets.

Abstract: Communication cables with cores that have groups of conductor pairs, that carry messages in opposite directions, in the same cable present the problem of crosstalk between the different groups. With the increase in carrier frequency that is used for communication, the crosstalk problem increases, and cables that were acceptable for lower frequency are no longer adequate. This invention provides more efficient shielding; is suitable for higher frequencies; provides a stronger cable structure; and reduces corrosion of the shielding.

Abstract: This method makes plastic book covers which have stiffer front and back panels and which have diminished plasticizer migration between the cover and any contacting cover or other adjacent surface. The covers are cross-linked to a limited extent to improve the elasticity of the hinge lines; and to a greater extent at the back and front cover areas to add stiffness to the plastic material. Laminated plastic covers are made with the different layers made of material that responds to cross-linking chemicals or radiation to different degrees, The covers can be made of expanded plastic and laminates.

Abstract: In some critical use, air-drying systems, 100% back-up capability is desired. The problem has been that an idle standby unit requires considerable time to reach full capability for dry air delivery. This invention bleeds enough dry air from the operating primary unit through parts of the idle back-up unit to maintain any dynamic conditions that are necessary to keep the standby unit ready for immediate use in the event of a failure of the primary unit.

Abstract: This invention provides a method and aparatus for welding together paper sheets, more especially for, but not limited to, bookbinding. The sheets are held in a desired relation with one another, and the portions to be connected are held together while subject to ultrasonic vibration which fuses ingredients of the paper so as to weld the fused areas together. A folded sheet can be welded across a midportion thereof and then folded along the weld or parallel to the weld to make a signature for a book; or stacked sheets can be bound together along their rearward edge portions by the ultrasonic vibrations.

Abstract: This invention is a fibre optic communication cable in which the signals are transmitted by light. The glass fibres used for the cable are protected from breaking strain and from excessively sharp bends by supporting helically wound optic fibres on the inside of a tension element with provision by which the diameters of the helical convolutions can become smaller to increase the axial length component of the optic fibres when the a axial length of the tube is increased by forces that strain the tube. Several ways of maintaining the helically wrapped optic fibres supported from the tube so as to permit decrease in the diameter of the helix are described and illustrated.

Abstract: This cable for high-voltage, alternating current power transmission cables not only reduces the access of moisture into the cable but reduces access of moisture to the inner face of the insulation to such an extent as to make the cable highly resistant to the formation of electrochemical trees in the solid extruded insulation of the cable. A compressible layer of closed cell, foamed plastic is extruded over the outside surface of the insulation; and a metallic shield fits tightly around the compressible layer, the metallic shield being a longitudinally folded tape with a lap seam which is preferably bonded to prevent ingress of air or other fluid into the cable. If the conductor is stranded, sealant is used to prevent ingress of moisture, or of air, and the humidity it contains into the cable at cable ends.

Abstract: The application of low loss optical fibers in optical communication systems requires that the glass fibers are suitably packaged into a cable. This invention provides a system of multiple optical fibers between two tapes or films, one of which holds the fibers on the film by pressure-sensitive adhesive and in spaced relation to one another. The fibers are covered by a second film, preferably thinner than the first film, and secured to the first film along the edges of the films to provide a laminated structure suitable for cabling. Spacers between the films eliminate asymmetric pressure of the covering film against the optical fibers which are nearest to the edges of the films; and the spacers are preferably strength members for stiffening the laminate.

Abstract: This electrostatic shielding tape is a metal strip of low resistance and low reactance folded longitudinally over the length of an insulated power cable having a semi-conducting insulation shield surrounding its insulation. The longitudinally folded metallic tape has its edges free to permit expansion of the insulation and insulation shield, located directly under it, without significant deformation of the insulation and the insulation shield. When the tape is of a metal requiring a thin corrosion-protective coating, the coating on the side adjacent to the insulation shield is preferably semi-conducting to accept charging current from the insulation shield. It is a feature that the metal of the electrostatic shield is in electrical communication with the insulation shield. .Iadd.
