Abstract: A filler cap is provided comprising a flange having a handgrip, a stem of square shape for engagement in a complimentary square shaped opening in the tank. The stem is comprised of two sections angularly offset relative to each other by 45.degree. and connected by inclined surfaces. Once the first section of the stem is inserted into the tank opening it is sufficient to rotate the cap by 1/8 of a turn in order to lock it in a closed position.

Abstract: The present invention relates generally to improvements in machines designed to form longitudinally extending slots in the shanks of fasteners and more particularly in fasteners having radially extending wings at the entering end portion. The machine incorporates an indexing dial with blank receiving pockets at the outer periphery thereof to transfer the blanks from a loading station to a slotting station. An orienting station intermediate the loading and slotting stations creates a rotary force on the shanks of the fasteners causing them to rotate relative to the pockets. The pockets include means to limit the rotation of the shanks therein by interengagement of one of the wings with an abutment surface formed in a recess in the pocket. The orienting station revolves the blank about its axis until the shank is properly oriented for the slotting operation.

Abstract: A mechanical assembly for rotating an axle comprises means for actuating said axle and means for fixing said actuating means together in which the axle comprises an end adapted to receive said actuating means. On this end, are at least one flat and at least one groove extending over a circular arc situated at right angles with respect to the flat. The actuating means is constituted by a knob or crankhead including a central recess adapted to receive said axle end and at least two flexible parts mounted in the recess and arranged at right angles to one another. One of these parts is adapted to bear on said flat and the other provided with a pin adapted to be engaged in said groove. The fixing means is constituted by a ring adapted to encircle and grip the two parts of the actuating means respectively against and in the flat and the groove of the axle end. The ring comprises means adapted to render it itself fast to the actuating means.

The contact terminal is deformed to provide angled surfaces on the contact terminal at the upper and lower surfaces of the base where the terminal extends from the base so that the angled surfaces of the contact terminal are wedged tightly against corners of the mold, thereby preventing the escape of plastic material from the mold during molding of the base around the terminal.

Abstract: Axial leads extending from opposite ends of electronic components are straightened by two pairs of fingers having pads which press on the leads and are rotated in opposite directions while they are driven along the leads. The straightening fingers have pads on their ends which are made of a soft resilient material, such as nylon. The fingers each have a cam follower on their ends away from the pads which allows the fingers to be opened and closed by the longitudinal motion of a cam on the end of a rod that is slideably positioned in a rotating tube. One end of the tube is attached to a support member and the fingers are secured to the support member. The finger pads are preferably shaped so that they overbend the lead by a small amount, such as 5.degree..
