Abstract: This invention is a terminal connector device for electrical wires and comprises a flap member movable under the action of an actuating button, which flap is interposed, in a biased position, between a terminal entry member and a wire receiving support. The withdrawal of said flap from this interposing position, under the action of said button, permits the introduction of the wire whose connecting is obtained automatically by lateral wedging of the wire inserted into said receiving support by the action of said flap, when the button is released. The button is lockable to hold said flap in its retracted position permitting introduction of the wire, which position also enables the disconnection of a previously positioned wire.

Abstract: There is disclosed a battery hydrometer for providing an analog electrical signal having a magnitude related to the specific gravity of a battery electrolyte.

The fastener includes a keeper and a locking means which requires the simultaneous application of a plurality of forces originating from differing directions in order to unlock the keeper for purposes of opening the fastener.

Abstract: A plastic clip comprises an insertion piece adapted to be inserted into the groove of an object having a section of the shape of the letter "C" from one end thereof, a neck portion projecting from the center of one surface of the insertion piece and adapted to pass along the slit communicating with the groove of the object, and an oblong head piece formed at the leading end of the neck portion. The insertion piece of the clip is provided with four flexible wings projecting outwardly from the four positions on the outer boundary of the central piece. With this clip, the object is fixed on a given panel by causing the central portion of the insertion piece to be slid into the groove of the object, then allowing the oblong head piece of the clip to be passed through a matched oblong hole bored in advance in the panel and finally turning the protruding oblong head piece by 90.degree., and the removal of the object from the panel is effected by turning the oblong head piece by another 90.degree..

Abstract: A housing unit is constructed substantially in a tightly closed state and divided by a partition into two chambers, one for encasing a fuel gauge and the other a strainer. The housing unit, on being attached to a fuel tank, simultaneously functions to indicate the amount of fuel in the fuel tank and strain the fuel to remove foreign matter therefrom.

Abstract: An apparatus for fastening an inside handle cover to an automobile door comprises an engaging leg integrally extended from the lower surface of a bottom plate of the cover, adapted to be brought into engagement with a hole bored in advance in a panel of an automobile body and having an insertion hole perforated along the axis thereof and ridges formed on the inner wall surface of the insertion hole, and a pin provided on the outer wall surface thereof with screw threads and adapted to be inserted into the insertion hole of the engaging leg; and facilitates the fastening of the cover to the automobile door and thereby improves the work involved and, at the same time, enables the cover fastened to the automobile body to be removed by a simple manipulation.

Abstract: A filling connection for vehicles driven by internal combustion engines, which is fastened in an opening of the car body and has one section disposed on the inside of the car body adapted to be connected to a line leading to the fuel tank, while a section disposed on the outside is provided with an inner or outer thread onto which a lid may be screwed, and an axially effective sbaling is arranged between the lid and the section disposed on the outside.

Abstract: A plastic retaining-fastening device comprising a retaining piece adapted to be wrapped around an article subjected to fastening and a pair of leg segments adapted so as to form one leg with check claws for insertion into a fitting hole bored in a given support plate on being juxtaposed to and pressed against each other, the improvement including having the retaining piece provided at the opposite ends; operating means adapted to release the check claws from their fast engagement with the edges of the fitting hole in the support plate. Owing to this improvement, the device once fastened to the support plate can be released from the support plate by actuating the operating means directly from the front side of the support plate.

Abstract: A fastener with a modified thread form discourages a nut from becoming irremovably frozen on the shank of a bolt. A first normal thread extends from a base reference surface to a height on the fastener shank to permit full thread engagement by a nut. Axially outwardly along the shank from that point, there is provided a second thread of reduced crest diameter but still of sufficient size to engage the threads on the nut. This reduction in thread diameter provides additional clearance to permit the nut to be backed off in spite of marred threads or paint or rust buildups.

One end of said male stud carrying a deflectable spherically shaped segmented head which permits limited tolerance variation between center lines positions of making bores in the two workpieces.

Abstract: There is disclosed a two-way valve which includes a single valve seat for controlling the flow of fluid in opposed directions through the valve responsive to differential fluid pressures across the valve. The valve includes first and second ports and a valve chamber. Across the valve chamber there is disposed a resilient diaphragm having an opening defining the valve seat. A ball valve element is supported in aligned relation to the valve seat and biasing means urge the ball element and valve seat into sealing engagement. When the pressure at the first port is greater than the pressure at the second port by a predetermined amount, the ball element moves away from the valve seat permitting fluid flow from the first port to the second port. When the pressure at the second port is greater than the pressure at the first port by a predetermined amount, the valve seat moves away from the ball element permitting fluid flow from the second port to the first port.
