  • Patent number: 5058404
    Abstract: The push-button lock arrangement includes a permutation chamber, and, in accordance with the invention, the combination of the permutation chamber can be changed without dismantling the lock arrangement and without the use of special tools. A cam, which is rotated by a simple screwdriver, activates the end of the lock-out slide of the permutation chamber to put the permutation chamber in its reset mode. The lock arrangement also includes a rotating stop member and a stationary stopper. The rotating stop member is connected to the outside door knob so that the rotation of the outside door knob is constrained to a predetermined angle of rotation.

  • Patent number: 5059076
    Abstract: A structure for preventing from readjusting an adjustment member, which adjusts an extent of operation by rotating the adjustment member, and more particularly, for preventing from readjusting an adjustment member in a carburetor. The structure for the adjustment member includes a hollow tube of a heat shrinkable resin to be fitted around the outer surface of a rotating operational portion of the adjustment member in such a manner that when the hollow tube is heated to be shrunk, it is securely fixed around the outer surface of the adjustment operational portion. Owing to such an arrangement, it will be impossible to fit a tool or the like onto the adjustment operational portion of the adjustment member once it has been available to the user, thus preventing the readjustment. Even if it is readjusted, the readjustment will be easily recognized during a particular inspection of performance.

  • Patent number: 5052199
    Abstract: A clamp device for securing the housing of PC's and similar equipment to a desk or table so that it can not be moved or stolen. The device is shaped to fit on the PC housing. Clamp pieces at the rear are made to grip the PC at its back by insertion of a wrench or screwdriver in sockets which drive threaded rods. Rotation of the rods causes the rear clamps to move forward or rearward. A key locking means at the front of the device, is used to block access to the clamp adjustment sockets, preventing the clamp from being removed from the PC. In addition, provision is made for insertion of blocking bars in the device frame, so that access to the PC disk drives can be denied.

  • Patent number: 5052204
    Abstract: A security device for an internal combustion engine comprising a valve for installation in either the air inlet, fuel inlet or exhaust outlet of the engine, and a lockable valve control mechanism. When installed, the valve is operable from within the cabin of the vehicle by means of the valve control mechanism to open or close the valve. The valve control mechanism can be locked with the valve in the closed position so that when a thief attempts to start a car in which the device is installed, the engine won't start or if it does it won't run for long.

  • Patent number: 5046342
    Abstract: A cylinder lock (1) has a standard lock mode (12 o'clock position) and a service lock mode (10 o'clock position). If the lock plug is turned to the service lock mode with the standard key (8) and left in this position, the plug can be rotated with the aid of the service key (9). The service key is latched against withdrawal, when the lock is in its standard mode. The plug can be displaced axially through a distance of about 0.9 mm, after inserting the standard or service key. A latching device (22) prevents axial return movement of the plug when an attempt is made to remove the service key with the lock in its standard lock mode. This can avoid unintentional jamming of the lock in the standard mode.

  • Patent number: 5044851
    Abstract: A fastening element is set in a receiving material, such as concrete, stone and the like, by driving it through the base of a blind borehole previously formed in the receiving material. When the fastening element is driven initially, it moves through a sleeve and expands and secures the sleeve in the blind borehole. Accordingly, the fastening element is fixed in the receiving material and is also secured by the sleeve in the range of the borehole in the receiving material. A fastening element assembly made up of a fastening element and a sleeve can be used.
