This paper presents some of the history of the Spacemetal process development; a discussion of the core forming machine, a description of the welder where corrugated core and facing sheets are joined; the quality control process employed for inspecting the finished product; and some of the material properties and applications. FOREWORD Development of a production process and the machines for fabrication of a resistance welded steel sandwich was made by Missile Division, North American Aviation, Inc. Development was carried forward under contract AF 33(600)-26154 from the Manufacturing Methods Branch, Industrial Resources Division of the Air Materiel Command USAF.

The last 20 years have shown a tremendous increase in the use of synthetic materials in the construction of low temperature bodies. This paper gives a brief comparison of the metals and the invading synthetics and outlines the design advantages of the use of synthetics. Included in this paper is also a simple theory which adapts itself to the determination of heat rise versus time in the media contained in an insulated body.

Recent developments to overcome the lower power and idle fuel consumption features of the automotive gas turbine engine have led to a new concept for applying this type of engine in military heavy-duty, off-the-road vehicles. In this application, a “siamesed” turbine configuration is employed, in which the compressor is split into two separate components. One component supplies air for the gas generator section and the other supplies air for the power section of the engine, both systems being selectively coupled by an arrangement of hydromechanical and aerodynamic links. The many advantages of this unique concept are described.

Advances in telemetry have produced techniques for the observation of phenomena that were not previously amenable to mensuration. An analysis of types of sensors such as mechanical, generator, resistive, and reactive is presented together with data pertaining to their operation. Means of transmitting and recording sensor data are also evaluated. Improvements in telemetry indicate that future testing equipment will be simpler, more reliable, and will operate with a greater degree of accuracy.

The technical specialty Value Engineering, conceived during World War II in General Electric Co., today is recognized as an effective approach for product improvement and technological advancement, and for cost reduction. In recent years, many consumer and defense industries have augmented their efforts to reduce product costs by introduction of value engineering programs. This paper: (1) provides a history of value engineering; (2) describes philosophy and techniques of value engineering; (3) demonstrates the effectiveness and acceptance of value engineering by presenting results of programs instituted in several companies; and, (4) relates experiences and procedures at Eclipse-Pioneer Div. of Bendix. The case study is presented with emphasis on the impact value engineering has on top management and management personnel.

This paper covers the design, development, and testing of a new product design of a stand-up model fork lift truck, which began in 1961 and was completed in late 1963. They are a production product line now, and are offered in load capacities of: Model MSA20 - 2000 lb at 15 in. load center. Model MSA25 - 2500 lb at 15 in. load center. Design objectives are outlined in relation to the final product design. Also detailed are certain development problems which were encountered.

Road test methods are described by means of which the total drag force, the air drag force, the tire drag force, and other drag components of a truck can be measured. The road tests consist of coastdown experiments over a wide speed range at several loads. Independent measurements of tire drag force and air drag force demonstrate that these road data are essentially correct. Examples of results of the road test method are shown for a few large transport trucks.
