Abstract: A split collar for surrounding an article comprises two half sections, each having an internal surface configured to engage the article. A pair of grooves surrounds the collar, and a cut-out is provided to form a pair of attachment projections. An elastic member, such as a rubber band or O-ring, is folded in half and one end is placed around one of the projections. The two strands of the folded elastic member are then placed in the grooves and drawn around the two half sections. The other end of the elastic member is then stretched over the other projection, whereby the two half sections are held together. The collar is suited for many uses, such as covering the junction between the telescoping tubes of a motorcycle fork assembly.

Abstract: A system for continuously monitoring and/or controlling blood hematocrit levels is disclosed. The system includes a photometric hematocrit sensor which is coupled to a linear response meter, and in one embodiment a separate sensor is coupled to a three-way solenoid valve. The sensor is responsive to the hemoglobin density in the optical path. The valve system automatically causes diversion of solution having a degree of hematocrit dilution below a set minimum. The sensor is independent of the amount of oxy-hemoglobin (HbO.sub.2) and reduced hemoglobin (HHb) and the system allows for instantaneous detection of improper hematocrit levels and obviates the need for time-consuming and unreliable centrifugal micro-hematocrit tests.

Abstract: Dry food quality protein and lactose powders are produced from cheese whey by sequential ultrafiltration processes, each of which removes as permeate substantial amounts of water and dissolved solids from the respective concentrates. In the initial protein recovery process, the concentrated protein fraction is pasteurized to inhibit bacterial growth and is evaporated to produce a protein substance which is palatable, highly soluble in water and rich in essential amino acids. The lactose concentration step produces a fine quality sweetner of excellent solubility and food value. Temperatures and pressures are carefully controlled in the first two processing operations. A third operation removes additional solid material which can be easily disposed of and a fourth operation reduces the BOD of the remaining liquid fraction to the point that it can be discharged into rivers or streams.

Abstract: Children's playground toys constructed from used tires are coated with an epoxy resin coating which is resistant to abrasion, temperature fluctuations and which adheres firmly during flexing and stretching of the tires during use. The coating enhances the visual appearance and functional characteristics of the equipment and prevents rub-off from the tire bodies onto the skin or clothing of children using the playground toys.
