Abstract: A hose clamp may include a body portion having an annular shape which is open at one portion and surrounding an external surface of a hose and an external surface of an object to be fastened, a stationary portion coupled to an external surface of one end portion of the body portion, a movable portion coupled to an external surface of an opposite end portion of the body portion, and a fastening portion coupled to the stationary portion to be movable along axial directions of the body portion. The fastening portion moves along one of the axial directions of the body portion and presses the movable portion in a first circumferential direction of the body portion such that the one end portion and the opposite end portion of the body portion move toward each other and the body portion inwardly presses and fastens the hose and the object.

Abstract: An open hose clamp with a tightening mechanism in the form of a so-called Oetiker ear. The tightened condition is locked by toothed portions which mutually engage outside the area of the ear on the side of the ear remote from the outer clamping band end. In the locked tightened condition, the ear is free of forces so that the hose clamp retains its clamping function even if the outward projecting ear is damaged.

Abstract: Techniques for detachably joining a first component and a second component includes a band clamp, a tensioning device, a plurality of shoes, and a plurality of brackets. The band clamp is configured to cause the plurality of shoes to engage an abutting cylindrical flange of each of the first component and the second component and to provide a sufficient clamping pressure to join the first component with the second component. Each of the plurality of brackets is attached to one of the first component and the second component. The sufficient clamping pressure results from redundant, independently inspectable, sources, a primary redundant source being circumferential tension in the band clamp, caused by tightening the tensioning device, to produce a first radial restraining force on the shoes, and a secondary redundant source being a second radial restraining force, applied by way of the plurality of brackets, to the band clamp.

Abstract: An annular-shaped, expansion type clamping band has laterally overlapping ends, each having a skewed surface, the skewed surfaces slidably engaging one another. The ends are further provided with elongated guide slots for receiving a threaded bolt. A threaded nut threadly engaging the bolt, when tightened, moves the overlapping ends toward a longitudinal central axis of the band whereby the band expands to exert an outward radial force against an interior surface of a gasket to provide a liquid-tight fit between the gasket and an opening having a surface engaging an outer periphery of the gasket. The band may be a one-piece or two-or-three-piece assembly and may be formed of an suitable metallic or plastic material. The threaded member is slidable along the aforesaid guide slots enabling the bolts to be self-centered. The nut and bolt assembly, in one embodiment is designed to require only one tightening tool.

Abstract: A positive release bracket (16) for an object such as an electrical connector part (12) includes first and second semicylindrical shells (18,20) which are releasably held together by plates (36,38).

Abstract: A band assembly for effecting a seal particularly adapted for use in establishing a joint between a sewer pipe and a reinforced concrete manhole riser. The seal is affected by a tapered elastomeric tubular connector boot and a clamping band member with an expansion mechanism. Wedge followers are loosely captured in the end sections of the clamping band and lie along a circumferential center line on the band. Driving wedges extend along an axis transverse to the circumferential center line. The wedge followers and wedge drivers both have divergent edge sections that interengage and slide over one another as the driving wedges are pulled together by a clamping mechanism comprising, in a simplest form, a nut and bolt. As the driving wedges move toward the circumferential center line, they displace the wedge followers. The wedge followers engage the end portions of the clamping band and force it and the connector boot into a sealing relationship with the surrounding manhole riser.

Abstract: A clamp for tightening heating coils around a cylindrical object being heated has a split tubular housing with straps extending from each housing edge and forming loops pulled together by forces exerted from a pair of wedging elements with conical surfaces. The wedging elements have a cylindrical portion journalled in loops connected to one housing edge and a conical inner portion on which a strap connected to the other housing edge is mounted. Movement of the wedging elements axially with respect to one another changes the effective diameter of the conical portions engaging the strap. This causes the housing edges to be pulled together. Movement of the wedging elements with respect to one another is provided by securing one element to a mounting pin and providing a threaded bore through the other element, the element with the bore being restrained from rotation. When threads on the pin engage the threaded bore, the elements are pulled together.

Abstract: An improvement in cam operated clamps for clamping heater elements to the nozzles of injection molding equipment. The clamp is adjusted by the rotation of a cam shaft parallel to the nozzle axis. The clamp housing consists of a circular cylinder with a longitudinal slit. Journals for the cam shaft are mounted on one side of the slit and the cam follower is mounted on the opposite side of the slit. Adjustment of the cam shaft increases or decreases the width of the slit providing the clamping action. Attached to the clamp housing is a tab which stops the cam pin rotation at an optimum position just beyond the position of maximum clamping effect. This position provides substantially the maximum clamping effect available from the clamp and effects a torque on the cam pin which holds the cam follower against the stop tab locking the clamp in place.

The proximal ends of the clamp halves define a pair of ramps tapering in opposed directions. Each of first and second wedges engages one of the pair of ramps. A threaded member, threadedly interconnecting the wedges, draws the wedges toward one another to urge the proximal ends of the clamp halves toward one another into gripping engagement with the circumscribed pipe through the wedging action mainfested by the pair of ramps.

Abstract: An electrically conductive cable is held within the inner bore of a well tool connected to coiled tubing by a clamp which comprises a split ring having radially outwardly extending lug portions on the split ends of the ring. The lug portions are located within a longitudinally upward slot of a sleeve located within the inner bore of the well tool. Upon application of tensional force to the cable, the lugs of the split ring clamp are drawn into the taper thereby compressing the split ring in tighter engagement with the outer surface of the cable.

Abstract: A clamp housing for cylindrically wound heaters, particularly for an injection molding nozzle heater has a slit that permits changing the effective diameter of the housing and it is actuated by an axially extending cam pin that can be easily adjusted from an exposed end of the heater. The cam pin has a central cam portion formed between two end hubs that are rotatably mounted with respect to one edge of a longitudinal slit in the clamp housing, and a central cam portion that is mounted in a loop formed from the opposite edge of the slit in the housing. As the cam pin is rotated the two edges of the slit in the housing can be forced together because of the cam action and the housing will tighten around a heater held on the interior of the clamp.

Abstract: A clamping ring for use e.g. as a support around a jointing sleeve during explosion welding consists substantially of two preferably equal ring halves (1,2) connected to each other over slots (3) limited by flanges (4,5) comprising surfaces (6,7) which form an angle (.alpha.). The surfaces co-operate with opposing surfaces (10,11) on an annular clamping member (9) which enclosed the flanges. Means, e.g. screws (12), are provided for bringing about a wedging action by displacing of the clamping member in relation to the clamping ring, thereby varying the bore circumference of the clamping ring. The force uniting the clamping ring halves is completely taken up by the clamping member (9) and does not stress the screws (12).
