SYNOPSIS Aluminum cylinder heads have been widely used on automobiles during the past fifteen years to increase the efficiency of engine operation. The great majority have given satisfactory service during many years of use and high mileages. In 1938 their use was greatly curtailed because of competitive costs. The competitive situation now prevailing favors the re-adoption of aluminum cylinder heads. Because of this, it is fortunate that the two problems formerly associated with the use of aluminum cylinder heads have been solved. One was difficult removal resulting from corrosion at the stud clearances. Tests have shown that this can be prevented easily by the use of cap screws, larger stud clearances, or stud coating compounds. The other problem was corrosion at the coolant inlet ports. The causes and means of prevention of this difficulty have been determined recently by means of road tests of seventeen automobiles, and cyclic tests of V-8 engines with divided radiators.

A SURVEY of recent developments in the field of air brakes is presented here. For instance, improved versions of the compressor, brake valve, relay emergency valve, and the hose coupling are described. The rotochamber, which is an improved type of brake chamber is covered, as well as a new, combined quick-release and limiting valve, and also the protection valve, which seals off the straight air and emergency trailer connection on the tractor, should the trailer break away. The author also emphasizes the importance of maintenance in keeping the brake system operating at top efficiency, for he believes that most of the chronic braking troubles being experienced today on heavy-duty vehicles could be eliminated if the brakes were analyzed and then subjected to a well-planned and executed periodic maintenance program.

THE authors have found that of the many factors influencing ground and direct costs, these five have the greatest effect: 1. Payload. 2. Ratio of payload to number of passengers. 3. Number of ground stations. 4. Average length of passenger journey. 5. Administrative policy and efficiency. The effects of these factors on a sample airline are shown in a series of graphs.
