Abstract: Apparatus for delivering a heavy cable such as a rescue cable from the oc's surface to an extended depth for attachment to an object such as a stranded submarine and, after attachment of the free end of the cable to the object, delivering the cable to the ocean's surface. A syntactic foam float provides positive buoyancy for a frame assembly which supports a cable reel holding the heavy cable. Releasable ballasts are included to provide an initial overall buoyancy of a small negative value during the descent of the appartus. A release system is provided to simultaneously release the releasable ballast to change the buoyancy of the apparatus to a positive value, release the cable reel to allow cable payout. The cable reel is coupled to a waterbrake system which limits the rate of cable payout to below the rate of ascent of the rescue cable reel. The waterbrake system includes a depth-activated clutch which engages a secondary waterbrake to slow the rate of cable payout near the ocean surface.

Abstract: In a machine for cement lasting side portions and the heel seat of shoes, the side portions are lasted by lasting rolls and the heel seat by wiper plates. For applying adhesive, each lasting roll has an associated nozzle which applies adhesive progressively in advance of its associated lasting roll. Furthermore, when the lasting rolls reach the point of termination of side lasting, they remain in pressing engagement with the shoe bottom, but their rotation is terminated, and in this condition the nozzles continue to apply adhesive in the heel seat region. This may be achieved by merely discharging adhesive from the stationary nozzles and allowing it to run into the heel seat, or alternatively the nozzles may track bodily into the heel seat. Thereafter, the lasting rolls and nozzles are retracted and heel seat wiping can take place. The invention may also be incorporated in a machine in which the whole of the shoe bottom is lasted.

Abstract: In constructing a stayed girder bridge, the end abutments and intermediate permanent bridge supports are built in place. The stiffening girder is formed of reinforced concrete or prestressed concrete and is built in sections at a location adjacent one of the abutments. As each section is built, it is connected to the previously produced sections by the reinforcing used, and the stiffening girder is moved from the one abutment toward the other by the length of the sections. When the girder reaches the other end abutment, a reinforced concrete tower is constructed upwardly from the girder at a location spaced from the abutments. A pair of stays are constructed of prestressed concrete each secured at one end to the other part of the tower. From the tower each stay extends in an opposite direction diagonally downwardly to and is secured to the stiffening girder.

Abstract: A transportable bridge unit has bridge spans located side-by-side and held apart with a space between the spans by crosspieces which include spars connected heightwise to the bridge spans and to a central transverse web in a manner that enables the spans to change their positions relative to each other.

Abstract: An interproximal toothbrush comprises an elongated metal handle terminating at one end in a threaded section. The stem of a twisted wire brush passes through a hole in said threaded section, humps up above the threads, and then passes down into a groove in the handle. A nut travels on the threads until it encounters and seizes upon the hump in the twisted wire. This way, the brush is securely locked into position, but the nut never touches the stem in the area of the brush. Thus, the brush is not damaged by the locking nut. A second hole in the handle receives a toothpick.

Abstract: A chimney cleaner of universal application and especially suitable for cleaning heavy wood resin residue is disclosed. An A-frame assembly capable of expansion and contraction to accommodate various chimney sizes is held together by pivot connections.

The legs of the A-frame end in wheels which ride up and down the chimney corner opposite the brush. The chimney cleaner's overall dimensions may be increased or decreased by applying a torque to the rod which, through a threaded connection with a leg, will cause the legs to spread or contract.

Abstract: A controlled deflection roll comprising a stationary roll support and a roll shell rotatable about the roll support. The roll shell is guided in radial direction upon the roll support in order to perform displacement movements, typically lift movements. The controlled deflection roll is equipped with a shutoff element, a slide or a valve, which upon exceeding a given displacement magnitude of the roll shell causes outflow of pressurized fluid medium from a pressure line, and thus, prevents the development of the full pressing or contact force which otherwise could lead to destruction or damage of the roll shell. In an overflow line, branching-off of the pressure line, there can be arranged a residual pressure regulator equipped with valve means or throttle means for preventing drop of the pressure in the pressure line below a desired value.

The sleeve is connected with a source of pressurized liquid through a conduit in the support. The sleeve opens toward the shell. A spring normally urges the sleeve toward the shell. The sleeve is closed in the space between the support and the shell except where it opens toward the shell. The inner diameter of the section of the sleeve closer to the shell is approximately the same as the outer diameter of the sleeve more remote from the shell for improving the hydrodynamic force exerted by the "plug" of pressurized liquid inside the shell.

Abstract: This invention relates to a heating process and its apparatus in reducing air pressure within a chamber at a balanced level. The air within the sealed chamber is suctioned forcibly and discharged thereoutside by rotation of rotary means installed to the chamber. Then, the air pressure therewithin gets reduced at a balanced level. Meanwhile, air friction heat is generated by continuous rotation of the rotary means, thereby the inside of the chamber is heated by air friction heat. Any wet articles are incorporated in the chamber may be dried effectively, and energy consumption for heating and drying may be saved. Further, since high temperature heated air fully fills the chamber, the chamber itself may be used as a heat source.
