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.

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.
