Abstract: A central belt lock for safety belts, especially such belts for pilots and other aviators or for parachute jumpers, for the rapid and at the same time releasable connection of several belts which come together at a central point. To avoid the problem of having to carry out, during fastening or release of the belt, operations which impair the reliability of the lock, the rotary lock member is provided with a linearly displaceable device which is operated by finger pressure. This device is provided with at least one transfer element for temporarily releasing an arresting mechanism for the connection members. The linearly displaceable device is spring loaded counter to the direction which it is pressed, and when it returns to its starting position it moves the arresting mechanism back into the arresting position.

Abstract: A package for an urinary catheter consists of a generally rectangular tray with an open top, to which a peel-back cover is bonded, containing a catheter assembly, a syringe prefilled with bacteriostatic water, and two gloves. The catheter assembly is designed such that a urinary catheter may be simply and efficiently placed into the bladder under sterile conditions. The catheter assembly consists of a heat shrunk seal to hold the end cap, three intermediate caps with antiseptic soaked sponge tips bonded to the ends, and the tube-like guide in proximity therewith. The catheter passes through the guide after removal of the heat shrunk seal and the systematic removal and utilization of the end cap and the three intermediate caps. A protective shroud encloses the distal end of the catheter, as it is bonded to the guide. A biocompatible lubricant is contained between the third intermediate cap and the guide.
