  • Patent number: 10518746
    Abstract: Trailer theft is a widespread problem, and existing locks have failed to solve the problem for a number of reasons. Some locks require permanent modification of a trailer jack, while others are easy to break into. The present invention provides a detachable trailer jack locking assembly including a retention shell couplable to a trailer jack body. The retention shell is sized and shaped to surmount an upper end of an outer tube of the trailer jack. The retention shell also includes a slot configured to accept a handle of a lifting assembly on the trailer jack. The assembly includes an attachment point disposed on the outer tube of the trailer jack. A lock is adapted to secure the retention shell against the outer tube by coupling with the attachment point. When engaged, the handle is immobilized within the slot, thereby rendering the lifting mechanism of the trailer jack inoperable.

  • Patent number: 8540013
    Abstract: A heat exchanger with a plurality of heat transfer plates between a frame and a movable plate employs hydraulic rams connected above and below the heat transfer plates to move the movable plate toward or away from the frame in a releasable clamping action against the heat transfer plates. A positive lock maintains the movable plate in its operational position. Supports above and below the heat transfer plates support and guide the movable plate and heat transfer plates. Thus, the heat transfer plates are removable from between the stationary and follower plates for replacement and maintenance when the movable plate is moved away from the frame without further reconfiguration or dismantling of the plate heat exchanger.

  • Publication number: 20100011818
    Abstract: A safety switch is provided in which the open-close condition of a switching contact provided in a lock mechanism is reliably switched in a manner coupled with a motion of a lock member between a lock position and a unlock position. Since a link member, which directly and simultaneously switches the open-close conditions of normally-open and normally-closed switching contacts pursuant to the motion of a lock member, is provided, the open-close conditions of the normally-open and normally-close switching contacts can be switched reliably in a coupled manner with the motion of the lock member between the lock position and the unlock position. As a result, for example, by monitoring the open-close conditions of the normally-open and normally-close switching contacts, it is possible to determine to which of the lock position and the unlock position the lock member has moved, that is, which of the locked state and the unlocked state the rotation of the drive cam is in.

The locking device is placed in ensleeving relation to an extended piston rod between a proximal hydraulic cylinder and a distal bearing point to prevent retraction of the piston rod. The device has a hollow sleeve configuration formed of confronting first and second sleeve parts that are hingedly connected to one another. A first lock secures the first and second sleeve members to one another along a longitudinally extending parting line. A second lock is opposed to the first lock and prevents hinged movement of the first and second sleeve parts relative to one another even if the first lock is defeated. The device is adaptable to a variety of hydraulic piston and cylinder assemblies.

  • Patent number: 6499324
    Abstract: A remote-controllable automobile anti-theft device replaces a common connection between the accelerator and the throttle of an automobile with a locking main shaft connector between an accelerator shaft and a throttle shaft. The locking main shaft rotates about a central axis in response to motion from the accelerator, and translates that motion to the throttle. The locking main shaft contains a hole. The remote control activates a push-pull solenoid which reversibly inserts a solenoid locking pin into the hole in the locking main shaft. When the solenoid locking pin is inserted into the hole in the locking main shaft, the locking main shaft is prevented from rotating around a pivot axis of the locking main shaft. Therefore, when the locking pin is inserted into the hole in the locking main shaft, motion of an accelerator shaft does not translate to the throttle shaft, and the automobile's engine cannot rev.

  • Patent number: 4314157
    Abstract: A safety lock for securing a radiation source in a radiography exposure device is disclosed. The safety lock prevents the inadvertent extension of the radiation source from the exposure device. The exposure devices are used extensively in industry for nondestructive testing of metal materials for defect. Unnecessary exposure of the radiographer or operator occurs not infrequently due to operator's error in believing that the radiation source is secured in the exposure device when, in fact, it is not. The present invention solves this problem of unnecessary exposure by releasingly trapping the radiation source in the shield of the radiography exposure device each time the source is retracted therein so that it is not inadvertently extended therefrom without the operator resetting the safety lock, thereby releasing the radiation source. Further, the safety lock includes an indicator which indicates when the source is trapped in the exposure device and also when it is untrapped.
