Tools made of ice facilitate forming of soft, sticky materials
Tools made of ice facilitate the forming or shaping of materials that are soft and sticky in the uncured state. The low-temperature of the ice slows the curing of the material, extending the working time available before setup. Handling problems are eliminated because the material does not adhere to the tool, and the melting ice serves as a lubricant.

Survey of man-made electrical noise affecting radio broadcasting
Survey, consisting of limited noise measurements, was made to augment and verify existing data at HF and VHF and to obtain basic data at UHF. Exact frequencies were determined by the absence of intentionally generated signals around three selected frequencies.

Concerning the sound insulation of building elements made up of light concretes
The sound insulating capacity of building elements made up of light concretes is considered. Analyzing differentially the behavior of light concrete building elements under the influence of incident acoustic energy and on the basis of experimental measurements, coefficients of correction are introduced into the basic formulas for calculating the sound insulating capacity for the 100-3,2000 Hz frequency band.

A cascade investigation of a convection- and film-cooled turbine vane made from radially stacked laminates
Heat-transfer was investigated on an air-cooled turbine vane made from photoetched laminates that were joined by diffusion bonding. Data from the investigation were compared with data of an impingement-, convection-, and film-cooled vane and a full-coverage film-cooled vane, and data of a transpiration-cooled vane.

The need to measure man-made radiation from orbit for spectrum management
Measurements of RF radiation from orbiting spacecraft are discussed as an approach to improving man-made radio-wave spectrum management for avoidance and prediction of harmful RF interferences. It is pointed out that a measurement program is required for acquisition of data on electromagnetic fields to be expected in orbits, and that several types of satellites could provide platforms for such missions. Papers by Reich et al. (1972) and Kelleher et al. (1972) are referred to for descriptions as to how such platforms could be used. An electromagnetic field spectrum measurement program is outlined for orbital missions.
