Abstract: A user of a self-powered electronic combination lock rotates an outer dial to cause generators to generate energy for storage in a capacitor bank. The user then rotates an inner dial to cause a microcontroller to sequentially display a combination of numbers, and presses the inner dial to select a displayed number. The microcontroller determines direction and extent of motion of the inner dial by receiving signals derived from Wiegand sensors placed in proximity to a magnetized disc which rotates integrally with the inner dial, and controls the display of numerals on an LCD display accordingly. When the microcontroller determines that a correct combination has been entered, it activates a motor to move a motor cam to act directly on a locking lever so that the locking lever can engage a drive cam integrally linked with the inner dial, to allow the inner dial to withdraw the lock's bolt.

Abstract: A roofing and/or siding unit and methods are disclosed, the units being formed of an appropriately formulated flexible foamed PVC material, and having a size, overall shape, and exposed surface configuration modeled after a traditional building material unit for which the units of this invention may be substituted (for example shake shingles, or various types of roofing tiles). The units are manufactured by an injection molding process wherein one part of the mold utilized is made by taking a metal casting of the normally exposed surface of one of the traditional building units so that substantial duplicates thereof are produced by the molding process. Since the units produced are similar in size, shape and the like to the traditional type units, workers need no special training regarding their application, which in most applications requires no techniques differing from techniques utilized to apply the traditional building units after which the units of this invention are modeled.

Abstract: A motorcycle anchoring device capable of being driven through asphalt, tarmac, or pavement, and to which a motorcycle can be tethered, thereby providing an anti-theft security when no other mechanism for securing is available. The device is in the form of a solid metal stake designed to be driven through the asphalt or tarmacadam commonly used in a paved parking lot or roadway. The stake includes collapsible barbs or flukes which retract while the stake is being driven into the ground, then deploy after the spike is in the ground, particularly as someone attempts to extract the stake from the ground. The barbs thus provide some in-ground stability, but mainly serve to prevent the spike from being raised. The exposed upper end of the spike is designed to permit secure tethering of the motorcycle to the stake, thereby securing against unintended removal and usage. Once the stake is no longer required, the stake is simply and easily driven completely into the ground.

Abstract: A protective cover for finery cases containing jewelry, precious metals and the like. The cover is made of nontransparent plastic sheets which are hinged together.

Abstract: A system for the secure transportation of articles such as cheques and bank notes comprises first and second docking stations at different locations, and a secure container which mates with the docking stations. The container has a number of lockable doors into which bank notes are fed by a feeder mechanism at the first docking station. The container has its own microcontroller which monitors the status of the doors and the integrity of the container, and which can respond to external control signals while it is in transit. Once the container has been loaded at one docking station, it is transported to the second docking station at a different location, where it can be unloaded. A one-time code is generated each time the container is loaded, and must be communicated to the second docking station before the container can be unloaded. Any attempt to tamper with the container while it is in transit results in the activation of a dye dispenser, which marks the contents of the container.

Abstract: A pass-through transaction drawer with a hinged, moveable security flap is disclosed to permit the conveyance of articles, in a relatively secure manner, between an attendant or clerk within a building and a customer outside the building irrespective of the drawer size or depth. The hinged, moveable security flap is only moveable by the attendant to maximize security. The security flap can be adapted with a small contents tray to facilitate transactions involving the exchange of money or credit cards. To facilitate transactions which may require deeper transaction drawers, the transaction drawer may be adapted with an interior partition to compartmentalize a relatively deep drawer, whereby relatively larger, bulky items are conveyed in the deeper compartment and smaller articles are conveyed in the shallow compartment.

Abstract: A door locking device with an antitheft mechanism comprises a main lock lever linked to a key cylinder and changed over from an unlock position to an antitheft position through a lock position, a sub lock lever linked to an inside lock button of the door and changed over to an unlock position and a lock position, and a linkage member having sufficient elasticity to connect the lock levers with each other between the lock position and unlock position. As the main lock lever is displaced from the lock position to the antitheft position the linkage member is elastically deformed and permits the sub lock lever to be left at the lock position, and as the main lock lever is displaced to the antitheft position the sub lock lever is composed so that it can not change over the main lock lever.

Abstract: A floor mat has a slip resistant upper surface intended for foot traffic and a backing layer intended to lay across a surface on which the floor mat is supported. The core of the mat is a woven roving sheet of fiberglass. A layer of polyurethane is bonded to the fiberglass, and beads are projected to impact the polyurethane layer when it is soft and tacky. The beads are sintered ceramic beads having a high coefficient of friction. At first, the beads are partially embedded in the polyurethane layer, then the polyurethane is heated to further embed the beads to 60-90% into the polyurethane. This leaves the crowns of the beads exposed, and in combination with the intervening expanses of polyurethane provides a slip resistant surface.
