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.

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.

Abstract: A pipe support strut system uses struts, each having a rigid sighting member having threaded shafts extending opposingly therefrom. Each shaft is provided with a correspondingly threaded nut having steel rod handles. A pipe extends coaxially around and outward from each threaded shaft and abuts the nut threaded thereon. The pipe terminates outwardly in a base plate having flanges for retaining a wooden block or pad against the internal wall of a large-diameter, flexible pipe prior to burial thereof.

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.

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.

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.

Abstract: The car locking device of the present invention has a latch to be engaged with a striker, a ratchet for preventing the reversal of said latch, an opening lever for disengaging said ratchet from said latch, a locking lever for changing over said intermediate lever and said opening lever between an engaged state (unlocked state) or a disengaged state (locked state), and the first and second change-over levers. The key device of a door is connected to said first change-over lever, and said locking lever is connected to said second change-over lever. Said first and second change-over levers are rotationally moved together by key operation between the locking position and the unlocking position, and in the case of the excessive turn beyond the unlocking position, the first change-over lever only is rotationally moved, with said second change-over lever and said lock lever kept stationary.

Abstract: The foot bearing the seat surface of a seat is divided at a distance of 20-30 cm from the seat surface. Between the mutually facing end faces of the two foot parts (5a,5b) a rubber cushion (9) is arranged, the circumferential area of which is widened to form a brake ring (11). The elastic restoring force, working counter to the inclination of the seat, of this cushion is reinforced by two further cushions (16,17) arranged within the foot parts (5a,5b). By means of the suitable arrangement of sliding elements with low friction (T1-T3), the mutual rotation between the two foot parts (5a,5b) is ensured.Thanks to this construction, the seat surface can be swiveled in a tumbling manner in such a way that every point of said seat surface moves on an imaginary spherical surface and thanks to the mentioned elastic restoring force, the seat part always returns automatically to its initial position.

Abstract: To provide lock servicing of particular door locks in common use, a bypass key (1) with key blade (2) long enough to reach through a lock-cylinder plug (26 and 45) and low enough to pass under extended tumblers (37) of a lock cylinder (28 and 43) in order to dislodge a tailpiece (36) from a stop-washer (63 and 45) or other attachment means at an inside end of the plug is provided in conjunction with a control key (14 and 21) with a key blade (13) of the same length into which single-lock and multiple-lock profiles (15) can be made to rotate the lock plug (26 and 45) and disengage or engage a lock cylinder (28 and 43) and its means of attachment to a door lock (54).

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.
