Title: Improvements in or relating to x-ray devices comprising a movable x-ray tube
IPC: H05G1/54
Filed: 1953-05-13
Abstract: 733,730. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 13, 1953 [May 15, 1952], No. 13367/53. Class 98 (1). Apparatus including a movable X-ray tube has a safety circuit the current in which is controlled by movement of the X-ray tube and renders the X-ray tube inoperative when this movement ceases. As shown, an X-ray tube 5 is mounted for rotation on an arm 6, which is movable horizontally in a bracket 7 slidable on a column 17. Switches 4 of a kind which are open while rotating and closed when stationary are mounted to be rotated by the three components of the tube movement, and are connected to three relays 14 operating contacts 20 in the circuit of the X-ray tube. When the switches are open relays 14 are de-energized and contacts 20 are closed, but when one of the movements of the tube stops, the associated switch closes to energize the relay and open one of the contacts 20 so that the tube 5 cannot be energized. Where the tube has a reciprocating movement, the switches may be rendered inoperative at the moment of change of direction, or the relays may be slow-acting. In another example, a disc driven by an electric motor has a spindle mounted thereon. An electric motor moves the spindle longitudinally at right-angles to the disc, and the X-ray tube is mounted on the spindle. The shaft of each motor carries a magnet which, when rotated, generates current in a coil to energize a relay to close a contact in the X-ray tube energization circuit.

Filed: 1942-09-29
Abstract: 556,851. Controlling motor vehicles. PIOTROWICZ, A. Sept. 29, 1942, No. 13644. [Class 79 (v)] Comprises an emergency brake and ignition control in which the steering hand-wheel is movable axially and when pulled towards the driver releases a spring which applies the brakes and breaks the ignition circuit. In the construction shown a wire C is connected at one end to the steering hand-wheel and passes through down the steering-shaft (not shown) to a pivoted catch E which normally holds a bar F in place against the pressure of strong springs G. In the normal position the bar F presses against a spring-loaded plunger AB the other end of which bears against a spring contact SP and so closes the ignition circuit. When the driver pulls the steering wheel towards him the wire C is pulled and the catch releases the bar F which is moved to the left to the position shown thereby breaking the ignition circuit and applying the foot and hand brakes through rods K, L attached to rods J sliding in casings encircled by the springs G. The bar F bears on lugs H fixed to the rods J and sliding in grooves Y in the casings. To reset the apparatus a pedal O is actuated and forces the bar F back against the springs G until it is held again by the catch E. The steering wheel-hand shaft is made in two telescoping parts splined together, so that the hand-wheel can move axially without disaffecting the steering gear. A spring ball-catch holds the hand-wheel in its normal position.
