Abstract: Improved metallic utility pole accessories used to either support objects on a utility pole or to support and stabilize the pole are provided. In general, the utility pole accessories include a polymeric chemically bonded coating that protects the underlying metal surface from corrosion. The coating also is substantially dielectric for preventing the accessories from interfering with the transmission of electricity through lines supported on the poles. The polymeric coating can be made from polymeric materials having functional monomers grafted thereto for chemically bonding with metal surfaces. Specific accessories within the scope of the present invention include crossbars, anchoring pins, transformer boxes, and guidewire supports. Also included is an improved insulator support post having a threaded portion made from a structural plastic material bonded to the polymeric coating.

A load sensing device may be provided for sensing the strain on the mechanical link. A measuring device 24 for measuring the resistance of the insulator 8 is provided to check the electrical condition of the load insulator, whilst a recording and indicating device allows for recording of electrical strikes and provide a lifetime expiry indicator.

Abstract: A bracket for fuse holders includes heat sink fins for cooling the fuse holders. The bracket has a main body conforming to the shape of the fuse holders and mounting members or feet which can be attached, using self-clinching nuts, to a printed circuit board on which the fuse holders are mounted. The heat sink is formed of fins attached to the main body. When space is limited, the fins preferably have a rectangular U-shape to provide increased cooling area. The main body provides structural rigidity to prevent the fuse holders from being dislodged due to torquing of the fuse holder caps.

Abstract: Herein disclosed is a piping/wiring clamping device which has a simple structure but can fix a piping/wiring element stably while allowing a tentative fixing. The clamping device comprises: a clamping wall formed by curing a band generally at its center for clamping at least one piping/wiring element fixedly; a pair of mounting walls which are formed to extend continuously from the two ends of the clamping wall and at least one of which is arcuated; engaging means formed at the extending end portions of the mounting walls for engaging with each other at their ends when the two extending end portions are pressed toward each other; and mounting holes individually formed in the mounting walls and adapted to overlap each other when the mounting walls are held in contact with each other.

Abstract: A heat processing apparatus comprises a reactor tube in which matters to be processed are housed, a wire-shaped heating unit enclosing the reactor tube, a support device for supporting the heating unit at plural positions, and reinforcing members for reinforcing the support device. The support device includes plurality of holders stacked one upon the others, each of the holders has recesses on those two faces thereof which are contacted with faces of its adjacent ones, and when the holders are stacked one upon the others in a pole, the recesses of the two adjacent holders stacked form a hole through which the heating unit is passed. The support device has support members each supporting a pole of the holders stacked and each of the holders is engaged with its corresponding support member.

Abstract: Disclosed herein is a novel and heretofore never anounced anchoring apparatus for telephone wire comprising a thickish plate-like base body of small size having a T-shaped suspending rod member protruded upwardly and forwardly from the upper side of the base body, three bores perforating the body in a front and rear direction for guiding set screws, a bore perforating the base body in a front and rear direction for guiding a set bolt, while the rear side of the body has a laterally elongated groove of a circular arc shape in section and a dent surface of circular arc shape in section along the longitudinal axis of the body.

Abstract: A pipe/wire gripping and fixing clamp comprises a gripping wall whose central portion is curved circularly and two attaching walls extending from either end of the gripping wall. The corners of the distal end of one attaching wall are cut off to define oblique edges, whereas the corners of the distal end of the other attaching wall are folded to define triangular hooks. When the one attaching wall is superposed on the other with a member to be secured being seated inside the curved central portion of the gripping wall, the oblique edges are latched by the hooks, whereby the member to be secured is reliably gripped and fixed by the clamp without causing any positional shift between the two attaching walls.

Abstract: An electric heater incorporating simple support structure therefor. A frame is insulated from an electric resistance heater coil by insulator supports mounted within beam members of the frame. The supports incorporate structural features enabling the use of simplified supporting beams. The support insulators include additional structural features for retaining the resistance wire in place and for simplified engagement therewith. The insulators may project on both sides of the support beams and retain heater wires in two planes. The support insulators further provide an integrated structure easily fabricated and simply assembled to the frame.

Abstract: A rail insulator (5) for the securing of a conductor rail (2) on a rail support (4) which comprises a substantially U-shaped supporting rail in which holes are provided at regular intervals, preferably in two parallel rows, and where the rail insulator (5) is formed with a notch (18) corresponding to the thickness of the rail being used, is arranged so that on the side turning away from the notch it has outwardly-extending, hook-formed holding elements (24, 25) arranged to grip around and be secured to the rail support (4), in that between the holding elements there is provided a guide stud (30) which fits down into one of the holes in one of the rows of holes. One thus obtains a rail insulator which is well-suited for use in the building up of rail areas, in that the rail insulator can quickly and easily be removed and mounted on the rail support without detracting from the strength and the ability of the rail area to absorb mechanical forces from changes in current.

Abstract: A wire clip for direct attachment to individual bricks of a masonry wall as a support and/or guide for climbing plants growing along the wall. The clip is a unitary wire member bent to the desired configuration and has a pair of opposite angular bent end formations and an intermediate outwardly projecting return bent formation which defines a loop when installed. The clip is slightly bowed and is spreadable so that the end formations engage opposite parallel longitudinal sides of an individual brick of the masonry wall with the clip disposed across the face thereof and the vine stem passing through the loop. Installation is effected by application of thumb pressure to the loop; disengagement can be effected by applying leverage thereto, all without any residual damage to the wall since installation does not involve digging into the brick or mortar.

Abstract: An interconnecting terminator bracket member and a resilient ring-shaped sleeve member are provided with a fastening means for releasably snap-locking the sleeve onto an electrical terminator for electrical cables without a need for nuts, bolts, screws, washers, and other conventional-type fastener hardware at the sleeve. The fastener means comprises two resiliently loaded spaced elements which project from an opening in the sleeve and a detent means which is formed within the bracket. The opening enables the two spaced elements to be squeezed or compressed towards one another. The detent means is uniquely configured to maintain the elements in a compressed state at the start of insertion, momentarily release the two compressed elements from compression forces exerted thereon during insertion, and completely enclose the elements when in the compressed state once insertion is complete. The fastener means is operated by inserting the elements when in the compressed state within confines of the detent means.

Abstract: A trellis arm and a support wire therefor. The arm has a hole in the first end to swingably attach the arm to a trellis post and a notch in its second end to receive the trellis wire. The support wire overlies the outer end of the arm, extends under the trellis wire and is attached to the top of the trellis post.The support wire may be in the form of a continuous loop.Various types of trellis arms have been proposed for supporting grape trellis wires but these trellis arms have not been as simple and efficient as is desirable.
