Abstract: A method for joining a belt having a reinforcement structure having a plurality of spirals connected to each other by transverse wires includes compressing the belt along two transverse compression zones and extracting a transverse wire while the belt is being compressed along the transverse compression zones.

Abstract: Provided is a cervical brace. The cervical brace according to the present invention may include an upper support that supports and covers a jaw of a wearer, a lower support supported by being pressed against shoulders around the neck of the wearer, a rear support that is positioned behind the upper support and the lower support and supports the rear of the wearer's neck, and a height adjuster including a body installed at one side surface of the upper support, a connecting member formed to extend from one surface of the lower support toward the body, and a rotating member that is installed at one side of the body such that the connecting member penetrates and rotates about the connecting member in both directions, wherein the body of the height adjuster moves upward and downward along the connecting member according to a rotating direction of the rotating member and thus the upper support moves upward and downward with respect to the lower support.

Abstract: The present invention discloses a rigid tie down in the field of mechanics, which addresses the problems of the existing tie downs, for example, they occupy a large space and have a low binding efficiency. The rigid tie down comprises a body, a first hook and a second hook provided on both ends of the body, and a handle connected to the body. The body has a cylindrical shape. The first hook has a first screw thereon, and the second hook has a second screw thereon. The first screw is threadedly connected with one end of the body, and the second screw is threadedly connected with the other end of the body. The direction of the threads of the first screw is reverse to that of the second screw. The rigid tie down could be operated in a convenient manner, have a high binding efficiency and occupy a small space.

Abstract: An extended length strand take up device is presented that may be used to repair damaged guy wires in the field. The invention comprises two connecting bodies connected by a single tension rod that extends continuously between the two connecting bodies. Each connecting body slides over opposite ends of the tension rod and is held in place by a stop member, such as threaded nuts screwed onto the respective ends of the tension rod. The connecting bodies may further include an inwardly-facing pull tab or tabs that can be used for pre-tensioning the guy wire. An alternative embodiment of the invention comprises a single tension rod that is fixedly anchored to the ground and several connecting bodies that are fixedly mounted along the end of the guy wire at standard increments. The tension rod runs parallel to and overlaps the end of the guy wire. The connecting bodies slide along the length of the tension rod until the required tension and length is reached.

Abstract: An injection device for injecting selectable amounts of a substance includes an activating mechanism including an axially moveable operating button which can rotated in a resting position only, a tubular drive element non-rotatably connected to the operating button, an axially fixed and non-rotatable guiding element, and an axially moveable driven member held non-rotatably in the device. A rotational grid is operationally between rotatable and non-rotatable components of the injection device such that the operating button can be moved two rotational directions when in the resting position whereby a selected amount of the substance to be injected can be selectively varied. For example, a dosage inadvertently selected too large by rotating the operating button too far in one direction can, in accordance with the present invention, be reduced by rotating the operating button in the opposite direction.

Abstract: A lifter is disclosed using two transmission mechanisms at two sides of a housing for lifting, for example, a bed or chair, each transmission mechanism including a motor. a worm gear wheel meshed with a worm shaft as the output of the motor, a screw rod threaded into an inner thread in the hollow gear shaft of the worm gear wheel, a push block fixedly fastened to one end of the screw rod and moved with the screw rod to lift/lower the load upon rotation of the motor, and a sliding block fixedly fastened to the other end of the screw rod to guide axial displacement of the screw rod in the housing.

Abstract: A load binder mechanism is disclosed that has an improved arrangement for connecting the hook and shaft end portions of the load binder to the elongated axially extending tubular body. The load binder mechanism of the present invention provides an axially extending tubular body having opposed end portions, each end portion being fitted with a sleeve that has both internal and external threads. The load binder mechanism includes first and second attachment members, each providing a shaft with an externally threaded portion. The attachment member shafts have respective right and left-hand thread patterns that engage correspondingly threaded internal bore sections of the sleeves.

Abstract: A turnbuckle having pivoting releasable anchors on opposing ends that when attached to different articles provides for moving one or both of the attached article toward or away from the other. The turnbuckle anchors comprise a plate incorporating housing for releasably receiving a turnbuckle eyelet and a blade extending from the base having a substantially triangular shape.

Abstract: A hoist or pulley adapter that fits upon an elevated “all thread” type rod or a threaded bold. The adapter includes engagement means that are adapted to receive the all thread or threaded bolt and are connected to a support member featuring an eyelet or similar opening structure to support a rope or pulley.

Abstract: An extended length strand take up device comprises at least two tension rods disposed in parallel spaced relationship to one another, and a first connecting body slidably mounted on the tension rods for connecting the extended length strand take up device to a guy wire, and a second a first connecting body slidably mounted on the tension rods for connecting the extended length strand take up device to a ground anchor. The first and second connecting bodies each include at least two side load tubes interconnected by a central web, each side load tube being slidably disposed on a respective one of said tension rods. A stop member at each end of said tension rods retains the first and second connecting bodies on the tension rods.

Abstract: A clamping device adapted to receive respectively in each of two linearly spaced members the distill end of a shroud line and a deck plate mount, the members being moveable along a threaded shaft to draw the distall end of the shroud line toward the deck plate member for attachment thereto; and a guage for determining precisely the linear relationship between the distill end of the shroud line and the deck plate.

Abstract: An insulator-jack for replacing damaged electrical insulators in a string of insulators comprises a pair of threaded rods disposed in substantially parallel relation to one another, a pair of coplanar spaced-apart insulator clamping collars, each being connected to opposite ends of the rods by a pair of lateral arms, wherein one of the insulator clamping collars is movably positionable along the threaded rods by a pair of ratchet members to selectively vary the distance between the two clamping collars. The non-movable clamping collar is provided with an upwardly and inwardly projecting safety tongue which engages the connection between the insulator clamped within the collar and the next-above insulator in the string, and is also provided with inward projections along the internal periphery to securely engage the insulator and thereby prevents slippage of the insulator.
