Abstract A pilot-scale fourdrinier former has been developed for the purpose of investigating the relationship between retention and paper formation (features, retention aids, dosage points, etc.). The main objective of this publication was to present the R-F (Retention and formation)-machine and demonstrate some of its fields of applications. For a fine paper stock (90% hardwood and 10% softwood) with addition of 25% filler (based on total solids content), the relationship between retention and formation was investigated for a microparticulate retention aid (cationic polyacrylamide together with anionic montmorillonite clay). The retention-formation relationship of the retention aid system was investigated after choosing standardized machine operating conditions (e.g. the jet-to-wire speed ratio). As expected, the formation was impaired when the retention was increased. Since good reproducibility was attained, the R-F (Retention and formation)-machine was found to be a useful tool for studying the relationship between retention and paper formation.

California dairy farmers producing and selling Grade A milk for pasteurization receive payment based on milkfat and solids-not-fat content of raw milk. In 1970, the concept of using electronic methods for testing of milk and its components was accepted by the California Department of Food and Agriculture. The InfraRed Milk Analyzer (IRMA) with its ability to measure fat, protein, and lactose, using a predetermined factor for the unmeasured solids, appeared to fill the need for a rapid, accurate, and economical method. After comparing IRMA results with chemical tests of known accuracy for several seasons, it appeared the ash factor could vary seasonally and geographically, as well as with individual dairy herds. It was decided to study the accuracy and calibration stability of InfraRed Milk Analyzers (IRMA), as well as the use of a constant value for the ash factor. By applying a multiple regression technique to milk sample data, it was possible to generate a model describing the relationship of fat, protein, and lactose to total solids (and solids-not-fat).

The relationship of specific heat of canine blood to hematocrit and density was determined at 37.46 C. Density is seen to give the better index of this property. The equation describing the relationship is: specific heat = 0.998 – 2.30 (specific gravity – 1). Submitted on October 6, 1961
