Abstract: A clamping ring for a sealing system has a channel for receiving flanges of the pipe connections and seals is formed of a plurality of segments, which are pressed radially on the flanges by a strap retainer, which has an arrangement for tightening the retainer on the outer portions of the segments.

Abstract: A clamp assembly (10) includes a corrosion resistant coated pipe (12) secured to a plastic two piece clamp (14). The clamp has a arcuate pipe receiving base member (16) and a flat cover member (20) that is snap fitted to the base member to clamp about the pipe. The pipe has a flat (22) that abuts the cover member such that the pipe is secured against axial slippage and rotational movement with respect to the clamp (14).

Abstract: The present invention is to offer a ratchet diving mask strap which can be adjusted to a desirable tightness even under water through a process of two-piece opposite direction displacement tightening by turning the adjusting knob to tighten the two sides of strap, and consists of one each elastic strap on the left and right, a guard cover an upper rack, a lower rack, a gear, an adjusting knob and a check device, wherein each elastic strap is combined with the left and right sides of the upper and lower racks to form a strip, the upper and lower racks are mutually overlapped and disposed in the guard cover, a gear disposed in the tooth grooves of upper and lower racks to engage with the upper and lower racks, and the gear is combined with the adjusting knob, turning the adjusting knob can displace the upper and lower racks left and right and further pull the left and right elastic strap so as to adjust the tightness of said strap, and the check device can check the adjusting knob to keep the tightness of mask

Abstract: A novel surgical clamp is provided for application to the liver, comprising an upper flexible band and a lower base, which are attached at their distal end. The proximal end of the lower base terminates in a handle. A worm drive apparatus for receiving the proximal end of the upper band is slidably mounted on the lower base. Clamping is accomplished by positioning the slidable worm drive apparatus, such that the length of the lower base between the apparatus and the distal end conforms to the inferior surface of the liver, and then gradually engaging the upper band with the worm drive apparatus, such that the upper band is compressed toward the lower base.

Abstract: An improved clamping collar of the type comprising a hooped band, one end of which mounts thereon a support for a rotatable screw which meshes with teeth stamped at the opposite end of the band. The support is formed by a portion having a U-shaped section which has longitudinal entrant portions which are fitted into the neck of the screw for providing the necessary support for same, and for preventing the screw from coming out on slackening of the clamping collar.

Abstract: A worm drive clip comprises a housing having a driving worm screw inserted therein, with the housing comprising an upper part and a bottom part for enclosing the worm screw and a flexible band with transverse ribs and transverse openings inserted in the housing. The band has transverse ribs and transverse openings equally spaced along its full length. The bottom part of the housing has means engageable with at least one transverse rib and/or at least one transverse opening of the band at one end of the band. The worm screw is engageable with the transverse ribs and the transverse openings at the other end of the band.

Abstract: A chuck key storage attachment for use with an electric drill for conveniently storing a chuck key. The attachment is retained against the body of the drill itself by a chuck key retention means which in turn retains the chuck key in the attachment. The chuck key storage attachment provides for several sizes of aperture for accommodation of the various sizes of chuck keys available in the market place.

Abstract: An improved hose clamp apparatus for alternatively clamping, tightening and/or release of a hose associated with a collar of an engine, motor, pump or the like, in tightly confined or constricted spaces most accessible primarily from a direction substantially parallel to the hose comprising, a rotatable geared shaft engaging and driving corresponding transverse slots formed in a flexible band surrounding the hose being clamped. When a sufficient axial force component is supplied to the shaft so as to defeat the spring biasing force and disengage a shaft member, rotation thereof is possible so as to alter the circumference of the flexible band and correspondingly loosen or tighten the clamp apparatus about the hose fitted upon the collar.

Abstract: A radially contractible hose clamp is provided with axially spaced serrations having inwardly facing openings and spaced gripping edges symmetrical about a centerline of each opening, with the serrations extending substantially the entire circumference of the clamp.

Abstract: The disclosure relates to a hose clamp comprising a band, a housing having a pair of juxtaposed legs having tabs engaged in load transfer relationship in an aperture in one end of said clamp band, and a screw journaled in said housing engageable with the other end of said band. A relieved area is provided between the legs of the clamp housing which permits the legs to rotate relative to one another about a point intermediate the width thereof to minimize spreading of the tabs and thereby to preclude rupture of the band at the aperture therein.

Abstract: A radially-adjustable wire grip hose clamp made of a single wire strand forming a pair of coaxial, axially-spaced clamping loops. Each loop having a portion progressively traversing a seat element as said clamp is adjusted by a radially-disposed screw threadedly engaging a nut and bearing upon the seat element. The traversing portions are maintained at equal length to stabilize the screw against tipping and a mechanical interlock configuration of bends retains the nut against torsion-induced angular displacement.

Abstract: Clip apparatus for use in securing a member such as a hose to a pipe or the like. The apparatus includes a housing secured to one end of a spirally configured flexible strip. A rotatable driving member carried by the housing is formed with threads engageable with complementary threads formed on the strip. Rotation of the driving member causes expansion and contraction of the strip relative to the pipe or the like. Slidable movement of the driving member disengages its threads from those of the strip.

Abstract: A clamp for pipes or the like has a band whose width is constant save for two recesses in the marginal portions of one of its end portions which is received in the housing of the clamp. The bottom wall of the housing has projections which enter the recesses and the recesses are bounded by S-shaped lugs, at least at those ends which are nearer to the respective end of the band. Such lugs abut against the respective end face of the bottom wall of the housing to prevent extraction of the band when a threaded portion of the band meshes with a tightening screw which is mounted in the housing and can be rotated in a direction to reduce the size of the loop between the end portion and the threaded portion of the band.
