Disclosed is a device for tightly gripping on the spinous process, installed between two spinous processes, with a horizontal hole through the main body, and two arc-shaped side plates connecting onto two ends of the main body, each plate having a through hole, and fastening on the spinous process, and a centrally placed item passing through a horizontal hole of the main body thereby connecting the main body and the two plates, and firmly fastened by a single or plurality of fastening items on one or two sides of the centrally placed item. Furthermore, the centrally placed item having at least one fixed hole section, and when the fastening items move toward the main body and tighten, the two plates change shape, putting pressure on the upper and lower gripping section of the two plates, this upper and lower gripping section therefore more firmly gripping on the spinous process.

A clamp for attaching a medical device to an OR table rail, including two closable clamp jaws that close to an extreme position that leaves inadequate room for the rail. A handle actuates the jaws apart, and a spring biases them together through a range of jaw positions. A lock member is biased to swing through a range of lock positions in which it progressively engages and locks the jaw mechanism through its range of jaw positions. A pair of bars carries the medical device on the clamp, and allows it to be adjustably positioned with respect to the rail.

A band clamp can be movably applied to an elongated object, such as a hose, conduit or the like, when the band clamp is in an open or non-engaged position. In one embodiment, the elongated object is gripped between a pair of arms which project inwardly from opposite sides of an inner circumferential surface of the band when the band is in its open or non-engaged position. The inner circumferential surface of the band also includes a pair of recesses, one on each side thereof. When the band is in its closed or engaged position, each of the arms is received in a corresponding recess. The first and second arms are attached at a common junction with the band forming an arc that is no less than about 180°.

A conveyor suitable for conveying objects along a transport direction, and related links, are disclosed. The conveyor includes a plurality of connected links, each link having a length extending across the direction of transport and a width extending along the direction of transport. Each link also has a body, a cam follower member, and at least one gripping member. A gear drive mechanism may be used to interconnect the cam follower member and the gripping member. The cam follower member is movable to selectively move the gripping member between a first position and a second position. The gripping member when in first position is disposed in an open position, and the gripping member when in the second position is disposed in a gripping position for contacting one of the objects to hold the object during transport. Gear-drive mechanisms of various designs may be used to interconnect the cam follower member and gripping member. A releasable holding member, such as a spring-loaded ratchet member, may be used to secure the gripping member in the second position. Multiple opposed gripping members may be used. Various modifications and options are possible.

The present invention provides an improved slip joint pipe coupling, which is reinforced by the mechanical compression of a split collar and sealing ring.

An electronic shelf label (ESL) holder, including an attachment member portion to be secured to a supporting surface, such as a C-channel, a holder member with protrusions for removably receiving and supporting the ESLs and, optionally, a cover member pivotally carried by the holder member to overly and protect the ESLs. The holder member includes a lip extending from at least one of the top or bottom fingers of the holder formed of flexible PVC material that is flexible relative to the remaining portion of the holder and is compressible for providing a tight fit of the ESL to the holder. The flexible lip is utilized in combination with a backing member which, in one embodiment, is a flexible PVC bead that extends along the length of the holder and, in a second embodiment, includes a relatively broad or wide pad of flexible PVC material that further provides a seal against the battery or other electronics of the ESL.

A novel panel-mountable fiber optic cable feedthrough is described that has two main body parts that can be brought together around a fiber optic cable and secured in place to prevent slippage of the cable. Use of two such main body parts that split along a plane that passes through the axis of the fiber optic cable allows joining the two main parts at any position along the cable without the need to thread the cable through a pre-formed cylindrical cavity in the body of the feedthrough. The main parts for this fiber optic feedthrough can be made by plastic injection molding suitably shaped to relieve bending strain in the glass optical fiber(s) within the cable. The foot-print for mounting such a feedthrough can be made compatible with that of a number of popular fiber optic connector mounts, including the SC-connector.

A heavy duty, large self-forming socket having a plurality of retractable gripping pins bundled in parallel and held in a frame within a housing is disclosed. The frame is positioned axially within the housing by radially extending, elongated hold elements that are positioned circumferentially around the housing. Slots in the housing exterior allow efficient inspection of the position of holes into which the hold elements are installed. A collar with shelf around the center pin protects the bias spring for the pin from over-compression. The gripping pins may be held to the frame by spring clips and / or a resilient O-ring. An adaptor is attached wherein a secondary operation is used to remove the adaptor from the square end of the socket. The self-forming socket is well suited for use with valves and controls for water, gas, sewage conduits and piping.

An adjustable wrench for gripping hexagonal and other shaped heads includes two slightly non-parallel jaw faces, wherein one face is smoother than the other. The angle between the two jaw faces is extremely shallow to create a “snap-action” geometry. Combining that geometry with jaw faces of unequal roughness can result in a desirable binding action that causes the wrench to tightly grip the head. In some cases, the wrench will continue clinging to the head even after the user releases the handle of the wrench.

A corner key includes a first body and a first engaging portion. The first body has a first slot. The first engaging portion is disposed on a surface of the first body and a position of the first engaging portion is corresponding to the first slot. The first engaging portion has a first section, a second section and a third section, wherein the first and third sections are located at opposite sides of the first engaging portion, the second section is located between the first and third sections, and a height of the second section is greater than that of the first section or the third section.

An X, Y positioning unit, mount or fixture is designed to adjust the position of an optical element mounted in the fixture so as to move it laterally and vertically with respect to the optical axis of the element, such that, once adjusted, the position is maintained through the clamping of plates about the positioning fixture to lock the hinges against movement. In this manner the adjusted position of the optical element is locked with high forces exerted by the plates on the fixture, with the locking technique not affecting the alignment. In one embodiment, the fixture includes live hinges which join an optical element holder to a fixed plate and pivot the holder about orthogonal axes crossing at the center of an optical element holder such that small movements of the hinged holder about the hinges adjusts the position of the center of the optical element holder and thus the optical element. The fixture in a preferred embodiment includes a milled block of metal having slots Electric Discharged Machined or High Speed Machined therein to leave thin flexible hinges, with positioning screws utilized to move the optical element holder about the hinges. When the appropriate adjustment has been made, the holder is clamped in the adjusted position to the fixed plate through the use of the clamping plates to provide a rigid structure capable of withstanding high static and dynamic loading. For laser target designator applications, positioning unit tolerance is less than one half micron, resulting in target designation boresight alignment errors less than 500 microradians.
