Nylon lung for respiratory diseases

CURRENT
Sub-Miniature Gyro-Compass Tested in Helicopter.-For the first time a true north-seeking gyro-compass of traditional battleship accuracy has been successfully operated in flight. For its initial flight, the beginning of a series of demonstrations to focus attention on the applicability of high-accuracy gyro-compasses over a wide range of military navigational requirements, the gyro-compass was mounted near the pilot in a conventional military helicopter. As regularly installed, it would be located out of the way, and only a repeater would be mounted with other instruments in the cockpit. The gyro-compass, which has no magnetic reference, is no larger than a paratrooper’s boots. It can be carried easily in one hand and is rugged enough to perform accurately in an Army tank operating in rough terrain. It has been developed by the Arma Division of American Bosch Arma Corp. Concurrent with the airborne tests, carried out by the Engineer Research & Development Labs., Fort Belvoir, Va., a general exhibition to the military was undertaken by Arma as a preannouncement showing of the division’s advances in gyroscopics, exemplified by the Subminiature Gyro-Compass which is now in factory production. Being proved are many facts which herald early solutions not only to the puzzling problem of all-weather, allarea helicopter navigation, but also solutions to many facets of navigating other airborne vehicles and land and water craft which are unable to accommodate the greater bulk of earlier highaccuracy gyro-compasses. Most important, perhaps, is that environment on land or sea or in the air does not deteriorate the high accuracy of the instrument. The compass neither has to be handled tenderly nor to be operated by

skilled personnel. Also, it is not susceptible to magnetic storms, changes in magnetic structure of vehicle frame, and d.c. fields from motor or radar operation. In addition, it eliminates deviation corrections and permits highlatitude operations. Although characterized as a “breadboard” demonstration, nothing was lacking. Installation and display packaging specific to helicopter and various other vehicle types is yet to come. Details of the Arma subminiature gyro-compass are not classified and the instrument may be made available for commercial as well as military operations. Nylon Lung for Respiratory Diseases.-A new portable respirator-a nylon lung-which is thought to be the smallest and most advanced machine of its kind in the world, has been invented by Electronic and X-ray Applications, Ltd., a London firm. Comprising a lightweight nylon jacket and a highly specialized pump-valve mechanism, the lung operates either from power mains or, in emergency, from batteries. The whole machine weighs no more than 80 lb. One section of the equipment provides manually operated breathing. This component is watertight, buoyant and extremely strong and might, for example, be dropped from an aircraft into the sea for immediate use in lifeboats or aboard ship in cases of drowning or severe shock. It is expected the nylon lung will help speed convalescence of patients recovering from respiratory ailments, since it enables them to move around fairly freely in bed, instead of having to lie supine, and to be comfortably transported from one place to another if necessary.
