Abstract: A padlock type security seal and method of making same include a U-shaped shackle, a pair of reversely bent end portions, and a transparent body having a pair of chambers for receiving the bent end portions. The chambers each have a locking groove therein for receiving the bent end portions. The seal elements are formed from two molded thermoplastic pieces, an insert and a body. The relative dimensions of the chambers, the shackle, and the locking grooves are chosen to prevent picking.The insert has a channel in which a liquid filled vial is inserted. The vial contains a colored liquid. When the shackle is attempted to be removed from the body portion, the shackle end portions penetrate the insert and the vial causing the liquid to seep into the various chambers, the seepage being visible through the body.

Abstract: A latch bolt actuating mechanism for a door having a latch bolt mounted on its inner surface adjacent a top edge thereof in position to engage and cooperate with a fixed keeper above the door includes an elongated strap having its top end connected to the latch bolt for vertical movement therewith and its bottom end connected to an actuator pivotally mounted in a rigid housing on the door surface by a removable shaft extending through the housing. The actuator is biased to the closed or latched position and a lever or strike plate extends from the housing in position to be pivoted about the shaft toward and away from the door inner surface with the lever being operable upon movement toward the inner surface to move said strap and the latch bolt connected thereto downwardly to release the latch bolt from the keeper. The rigid housing provides a stop for engaging said lever to limit the pivotal movement of said actuator and the downward movement of the strap.
Abstract: A door latch has a housing for installation in a prepared cavity at a door edge and has interchangeable faceplates for finishing the door edge. The interchangeable faceplates each have an opening for permitting extension and retraction of a latch bolt, have a peripheral shape required for compatibility with the prepared cavity, and have features providing for releasably securing the faceplates to the housing and to the door edge. This permits installation of door latches regardless of the door preparation by merely interchanging the faceplates to match the door preparation.
Abstract: A method is for selectively locking two frame members of a window or door to prevent sliding movement of one frame relative to the other. The method involves providing an aperture in one frame, securing a sleeve to the other frame in alignment with the aperture, inserting a bolt through the sleeve and into the aperture. The bolt includes two lengths which are pivotably connected together. When the bolt is in retracted position, one portion of the bolt can be pivoted relative to the other portion of the bolt and then moved along a line perpendicular to the axis of the first portion of the bolt.
Abstract: A vehicle door latch has a selectively activated security lock that prevents a vehicle door from being unlatched by an inside door handle. The security lock is activated and deactivated when the vehicle door is open by inserting a key or other probe-like instrument into a slot in an inner panel of the vehicle door to manipulate a moveable arm of the security lock.
Abstract: A latch arrangement for an access opening cover on a bulk material storage structure. The access opening will include a frame defining an opening periphery, with the covers hinged for movement between a closed position and an open position. Each cover will include at least one slide bar extending between sides of the cover. Each slide bar has a length such that the ends of the slide bar are in proximity to the frame. Lock studs extend inwardly from the frame, with one stud associated with each end of each slide bar. Each slide bar is mounted for sliding movement perpendicular to its longitudinal axis in the plane of the cover between latched and unlatched positions, and includes a stud face and a lock face. The stud face includes slits through which the studs may pass at the closed position of the cover, allowing the bar to drop down over the stud. When dropped down over the stud into the latched position, the lock face abuts against the stud, arresting movement of the bar.
Abstract: A plastic seal including: a body to which is connected at least one cord, provided with at least one end with a hook; an aperture provided in the body for insertion of the hook; a seat for housing the hook inserted into the aperture; a means for the irreversible retention of the hook to the body and a pair of closure plates applied to the body.
Abstract: A brittle thermoplastic molded cylindrical hollow hole seal has a top wall and a depending side wall. An annular external rib snap fits to an annular groove in a hole side wall to secure the seal in place. Axially extending angularly shaped in cross section grooves are on the side wall interior and spaced axially extending slots pass through the side wall. The top wall internally has an eight point star shaped set of ridges and troughs whose points terminate at the side wall forming the interior grooves. Reflective aluminum flakes are in the material to provide a spotty finish. The slots, grooves, ridges and troughs form weakening regions causing the seal to shatter in response to an applied local pressure, for example, exerted by a screw driver for use with a screw plugged by the seal. The spotty appearance is difficult to hide when the seal is broken.

The primary latch housing 32 is simply modified to provide for passage of the rod 26 through the housing for supporting the rod in the hood open position and for guiding its movement between that position and the closed position.
Abstract: In an infant-restraining protective seat, a cover seat (98) is tiltably supported on a turning shaft (20) which tiltably supports a seat back (3) on a seat portion (2). When the cover seat (98) is at a position at which it closes a second recess of a seat-portion body (7), the cover seat (98) forms a seat surface on the upper side of the seat-portion body (7). When the cover seat (98) is at a position at which it opens the second recess (14), the operation for fastening and unfastening a tongue (123) and buckle (124) of a seat belt device installed in a vehicle seat, which operation is performed in the second recess (14), can be performed with ease from above the front of the protective seat (1).
Abstract: A pawl latch that provides an integral gripping feature to facilitate opening panels and a visual indication of latch closure. The front portion of the latch has two pieces. In the open position, the two pieces are positioned with respect to each other so that the top piece reveals a colored face of the bottom piece. The colored face of the bottom piece can be observed at great distances from the latch. In the closed position, the top piece totally covers the bottom piece so that no color is visible on the latch. Further, in the open position, the front piece is at right angles to the bottom piece, and the front piece is positioned away from the panel so that it can be easily grasped with two fingers to allow the opening of an attached panel. Also, the latch is designed to be attached to a surface of the panel that is not horizontal to a frame to which the panel is to be secured to by the latch.
