Abstract: A soldering tool comprises a handle (10) and a rod-shaped or tubular heating element fastened to the front end of the handle. A soldering tip (4) can be placed on the free end of the heating element. The soldering tip (4) has a borehole for receiving the free end of the heating element and can be fixed to the handle (10) or heating element by means of a fastening sleeve (1). The end of the fastening sleeve (1) nearer the soldering tip has first rotary catches (2, 3) which can be locked by second rotary catches (5) arranged at the rear end of the soldering tip (4) by turning the fastening sleeve (1) relative to the soldering tip (4).

Abstract: A spherical joint and bearing assembly utilizes a ball and socket arrangement between a connecting rod and a crosshead in a power reciprocating fluid pump. The connecting rod is spherically shaped and is held in a thrust bearing having a matching interior surface. A split retraction ring is held between the rear portion of the sphere and a shoulder in the crosshead. The result is an increased bearing surface and reduction in misalignment.

Abstract: An integrated circuit is utilized to control a switch so the flash rate and duty cycle of a flasher system is accurately regulated. The tighter control allows two flash rate and duty cycle combinations whereby a driver perceives a significant difference between the two settings, normal operation and lamp out operation. Such a feature allows one flasher to meet all Federal Motor Vehicle Safety Standards when used as a combination flasher for a 3-lamp turn signal and a 6-lamp hazard warning lighting system in vehicles.

Abstract: A windscreen-wiper blade includes a moulded plastics holder constituted by a main bow with a central portion for the attachment of an operating arm and at least two secondary bows formed in a single piece with the main bow, and a wiper blade carried by a longitudinal support which is inserted between pairs of lateral retaining claws on the main and secondary bows. The main bow has two transverse centering and stop projections at its ends for preventing the support with its wiper blade from coming out of the holder longitudinally.

Abstract: An improved hook plate for a windshield wiper arm includes a first end portion for attachment to biasing spring, a central portion for mounting the hook plate to a wiper arm and a second end portion for mounting a windshield washer jet assembly.

Abstract: A sealing arrangement in which a sealing member 25 seals against an annular sealing surface 20. The sealing member 25 has an annular sealing surface 29 the axis of which is offset relative to the rotational axis of the surface 20. Thus when the annular surface 20 rotates the area swept out by the sealing member surface is larger than the area of its sealing surface. The arrangement has application to seals for gate valve stems.

Abstract: A fuse housing for an oil-cooled transformer that uses a stopper to prevent oil from escaping the transformer tank as the fuse and fuse holder are removed. During normal operation, the stopper is held in an open position by the fuse holder. When the fuse and fuse holder are removed, the stopper closes and seals the upper end of the holder, preventing oil from draining through the upper portion of the fuse housing and escaping from the transformer tank.

Abstract: An electrical plug assembly providing internal, adjustable gripping means and sealing means for electrical cords of various sizes. The internal, adjustable gripping means is a three-jaw grip assembly using pie-shape jaws which are slidably mounted on tracks and moved towards and away from the center of plug body to form a gripping circle around cords of various sizes. The cord seal consists of a notched rubber bushing formed between two rings. As the cover is tightened over the clamping jaws, the rings on either sides of the rubber bushing are urged together causing the bushing to collapse inward and seal the cord. The cord seal also provides means for locking the cord seal in place and increasing torque needed to remove the cover.

Abstract: An adapter providing electrical and water-tight mechanical connection between a spark plug cable and a high output terminal of a distributorless ignition system. An expandable, electrode extension is anchored in the ignition system terminal at one end and connected to the spark plug cable via a spark plug terminal at the opposite end. The extension fits within a rubber insert that is inserted into the ignition tower to provide a water tight seal.

Abstract: An adjustable hanger is slightly wider than the vertical vane and includes a horizontal slot through which the vane is pulled as it is installed in the hanger. To shorten the length of the vane between the hanger and the floor, additional vane material is pulled through the slot. The excess material that has been pulled through the slot hangs down on the opposite side of the vane and is invisible from the front of the blind. Each vane has its own adjustable hanger and can be adjusted individually.

Abstract: The method of making a miniature co-axial cable of the present invention includes the insertion of a pre-sized, conductive core into an outer cover with supporting material to center the core. The assembly is then heated and the thermoplastic cover and core supporting material is drawn down around the central core. The result is a miniature co-axial cable with a precise amount of air space, or dielectric region between the core and the outer cover.

Abstract: The invention is for a cord system for a dual function window blind. A looped cord acting with a master carrier controls the traversing movement of the vertical vanes. The other, smaller diameter cord controls the tilt of the vanes and is not a looped cord but a much thinner cord with a tassel attached at each end. The tilting is performed by pulling the tassels whereas the traverse is performed by pulling the heavier cord. The first, looped cord slides freely through holes in the tassels. The result is the appearance of a single cord with a tassel on each side.

Abstract: The tubing hanger seal assembly of the present invention includes a metal to metal seal that is energized from above by a drive sleeve. The drive sleeve is threaded to the outside of the tubing hanger and as it is rotated downward, engages a load ring which in turn energizes the metal to metal seal by compressing it between the tubing hanger and tubing head. In addition, the invention includes a split ring which is forced into a notch by the drive sleeve in the inside of the tubing head to prevent the seal from being blown-out by upward pressure.

Abstract: The rivet shaver driver element of the present invention includes an internally threaded hollow cylindrical body. At one end of the hollow cylindrical body is located a drive slot. Along the length of the driver element are spindle locking slots. Wrench flats are formed on the sides of the drive element. The placement of the drive slot spindle locking slots and wrench flats as such that the driver element is dynamically symmetrical.
