Abstract: A door for a computer case is provided which can be moved to a blocking position for blocking access to bays and/or drives of the case. The door can be attached to the case by a slide connection for sliding it along the front of the case between its blocking and accessing positions. In the preferred form, the case is a vertical tower type of case and the door is preloaded on track guides so that when it is raised such as to the blocking position it will not fall back to the accessing position under the influence of its own weight. A gear drive can be provided between the door and housing to provide for smooth manual sliding of the door to readily allow the door to be pushed to overcome the frictional resistance provided by the preload without hang ups in the track guides.

Abstract: A latch assembly of a padlock for sliding doors is provided with male and female plate members capable of effectively engaging with each other. The male member includes of a first mounting part having a plurality of screw holes and mounted to either a doorframe or a door, and a first bending part perpendicularly bent from the first mounting part. The female plate member is mounted to the remaining one of the door and the doorframe so as to vertically engage with the male member. The female plate member includes of a second mounting part having a plurality of screw holes and a second bending part vertically bent from the second mounting part. Therefore, the screw holes of the male and female plate members are respectively hidden by the second and first bending parts when the door is locked by a padlock.

Abstract: A clamping structure between a container body and a cover mountable thereon in an air-tightly sealable contained such as wafer carriers from semiconductor silicon wafers used for storage and transportation thereof. The clamping structure includes a container body and a cover mountable on the container body each provided with an encircling stepped flange around the open periphery. The stepped flanges on the container body and the cover are engageable each with the other. A pair of engagement tabs, each having an engagement groove, protrude from the open periphery of each of the container body and the cover at oppositely facing positions. Also, an engagement board which is resin plate is provided with a U-shaped openwork notch at the center thereof in a longitudinal direction.

Abstract: A hatch in road or rail tanker (2) includes a hatch cover (7) mounted in a flange (8) of a compartment manhole (9). In order to prevent leaks from the hatch cover (7), a band (13) is welded to the top of the tank (2) around compartment manhole (9). The band (13) includes an outwardly concave flange (14) providing a groove for receiving a hatch sealing device (15). The hatch sealing device (15) includes a generally cylindrical rubber cylinder having an open end and a closed end closed by a seal membrane, also of rubber. Around the inside of the rim forming open end there is provided an internally extending lip shaped to fit into concave flange (14). Around the outside of the cylinder is provided a split ring of metal, the ends of which are drawn together in order to radially compress the cylinder and thus seal it around the flange (14).

Abstract: A carton closure apparatus releasably and securely closes a carton having a rectangular bottom, four side walls, two minor top flaps connected to the shorter two walls, and two major top flaps connected to the longer two walls. The apparatus has two parts. The first part is an insert that has a planar surface and a latching member that extends away from and at a right angle to the planar surface. The second part is a socket that has a receiving member for releasably and securely engaging the latching member of the insert. The socket is attached to one of the shorter side walls of the carton at a point along the top edge and equidistant from the adjoining side walls. When the two major top flaps are folded over the two minor top flaps and the insert is placed into the socket with the insert's planar surface extending over a portion of each of the major top flaps, the carton is releasably and securely closed.

Abstract: Fitting for a door, window or the like comprising locking elements provided with at least one operating rod allowing the actuation of a mechanism for locking the leaf in rotation, in various angular positions, with respect to the sash-frame. This mechanism is composed of at least a clamping element and an additional member, one of which is made integral with an extension of the operating rod and the other one with the sash-frame. The clamping element and the additional member of the actuation mechanism are located on the rotation axis of the leaf, each comprising slits intended for co-operating with each other when actuating the locking elements. The clamping element further comprising connecting members intended for making same integral with either the sash-frame or the operating rod and with respect to which it can move with a stroke of a length at least equal to the height of its slits.

Abstract: A detachable two-part lid for a container wherein oppositely positioned wire members hold the two parts of the lid together when separated from the container and also provide a captured hinging of the lid parts when they are positioned on the container. In a preferred manner, a slot is provided in a guide and a gooseneck portion is provided in the wire members, so as to afford a wire rentention feature when the gooseneck portion is moved outwardly from the slot.

Abstract: A flexible flap, having an elastic memory, which flap is used to normally cover a lightwave connector so as to prevent laser radiation emissions from the connector. The flexible nature of the flap allows the forcible deflection thereof, so that a mating connector can be attached to the normally covered one, and yet when the mating connector is removed the flap will automatically return to the covering position. In addition to preventing the emission of laser radiations, the flap can reduce contamination materials, such as dust, from covering the end of the fiber optic material.

Abstract: A device for locking a rectangular electric meter box having an openable front cover. The device has an L-shaped lock housing which includes a first leg fixed to the front cover of the box and a second leg which is detachably fastened to the side wall of the box when the front cover is closed. A barrel lock is inserted into the second leg of the lock housing to block unauthorized removal of the detachable fastener from the side wall of the meter box.

Abstract: A locking assembly for electrical enclosures to prevent unauthorized tampering with internal power connections. The locking assembly comprises an adjustable bracket which is secured to the walls of the enclosure by bolts; a cover which covers the open front and a substantial part of the sides of the enclosure and which is secured by a bolt to the adjustable bracket, a locking shield which overlies and prevents removal of the bolt which attaches the cover to the adjustable bracket, and a removable lock bolt which secures the shield to the cover.

Abstract: Force-resistant locking devices for electric meter boxes with hinged cove or the like, comprise a stud member mounted to a wall of the box and a flange member received on the stud member, the flange member including a flange overlying a marginal portion of the cover to keep it closed. The flange and stud members together define an opening receiving and fully enclosing a utility lock for securing the flange and stud members together. In one embodiment, the flange member is an angle iron with rectangular metal stock welded to one leg, and the stud is cylindrical and received in an opening through the flange member. The lock-receiving opening intersects the stud-receiving opening and the shear strength of the utility lock holds the locking device together. In another embodiment, the flange member is a section of channel iron and receives a rectangular stud, the lock-receiving opening deployed to utilize the shear strength of the lock.

Abstract: A highly tamper-resistant lock for attachment to an electric meter box, as a supplement to other locking means, if any, or a replacement therefor, the lock having one part secured to the box and a separable part adapted to be locked in engagement with the first part and in a position to prevent separation of the parts to project in front of the meter box cover to prevent opening thereof. The part secured to the box includes a reinforcement member having at least one wing piece which engages a portion of the separable part in the locked position to prevent tilting of the separable part by prying. The lock for the separable part is shown as a plunger type lock, to be inserted in a deep tubular chamber.
