    Notes: The feasibility of using myosin, extracted from post-rigor bovine muscle, as a binding agent for meat pieces, was examined. Crude myosin was extracted with solutions containing various concentrations of sodium chloride (salt) and sodium tripolyphosphate (TPP). Maximum yield was obtained using 1M salt and about 0.25% TPP in the extracting solution. Binding strength, i.e. the strength with which pieces of meat adhere, of crude myosin extracted with 1M salt and 0.15, 0.25 or 0.5% TPP were not significantly different and were only slightly lower than that for crude myosin extracted from pre-rigor muscle. The myosin preparations had binding strength much greater than that reported previously for actomyosin. These results show that crude myosin extracted from postrigor bovine muscle has a potential use as a meat binding agent.

    Notes: Suspensions of myosin, actomyosin and sarcoplasmic protein, isolated from beef semitendinosus muscle, were prepared at several protein concentrations and with various amounts of added sodium chloride up to 1.4M. An aliquot from each suspension was pressed between two pieces of muscle of fixed cross-sectional area and cooked. Binding strength was estimated from the force required to separate the meat pieces. At salt concentrations up to 1M the binding strength of myosin was superior to that of actomyosin (P = 0.05 – 0.001), and that of sarcoplasmic protein was too low to be measured by the techniques that were used. However in the absence of added sodium chloride, a mixture of sarcoplasmic protein and myosin had greatest (P = 0.05) binding strength.

    Notes: Evacuation of the chamber of the press used to form flaked beef into a restructured meat product (patty) did not affect the binding strength of the cooked patty but under some conditions decreased the cooking loss. In studies using patty mixes containing 0–1.0% added sodium chloride, meat binding strength increased with decrease in the temperature of the mix when formed into patties over the temperature range - 1° to -5°C. The largest effect generally occurred between - 1° and -2°C. However, the effect was only noted in patties that were frozen (-30°C) before being cooked for assessment. With decrease below - 1°C of the temperature of patties when pressed, cooking losses increased for the patties without added salt but decreased for those with added salt (0.5% or 1%). Change in the pressure applied to form the patty (in the range 1.4–13.7 MPa) can affect binding strength.

    Notes: An improved method for the sampling of splash droplets carrying fungal spores uses fixed photographic film. Droplets left clear, permanent traces within which spores were easily visible. The droplet spread factor was constant because the gelatine layer was uniform. A comparison of estimates of the numbers of splash droplets, spore-carrying droplets and spores dispersed by a 5 mm drop falling onto a spore suspension (depth 0.5 mm) with those obtained by other workers demonstrated the reliability of this method. The accuracy was improved by semi-automatic analysis of the spore-carrying splash droplet traces with an image-analysing computer.

    Notes: Suspensions of crude myosin, sarcoplasmic protein and a mixture of both were prepared. Each was mixed with coarsely-ground meat in the ratio 1:10 w/w. The product was formed into frozen rolls, 6.5 cm diameter, from which steakettes 2 cm thick were cut. These were oven broiled to an internal temperature of 70°C and assessed by a laboratory taste panel. The binding strength between meat pieces was also objectively assessed. Overall, taste panel members preferred the products containing added myosin with salt to those without salt or with added sarcoplasmic protein only. Correlations between various attributes of the product were investigated. Significant correlations were found between overall acceptability of the product and flavor, juiciness, tenderness and the objective measurements in binding strength. Significant correlations also were found between the objective and subjective assessments of binding strength.

    Description: Residential winter thermal energy storage features water encapsulated into 3-in. (7.6-cm) diameter plastic pipes, mounted into conventional stud wall cavities of a house. With an air solar collector, solar-heated air can be passed through the stud cavities, heating the water. During the discharge mode, this water loses its heat directly to the house, and the radiating walls allow the residents to feel warm even at lower interior air temperatures. Empirical and theoretical component performance data are reported for the waterfall thermal energy storage unit. The interaction between a large air-heating solar collector and the waterfall thermal energy storage is considered for the winter heating mode. The collector-storage thermal integration analysis is detailed for a charging flow rate of 40 cfm per cavity. A simpler but reasonably accurate integration analysis is illustrated for 10 cfm cavity flow rate. Performance parameters indicate that the waterfall thermal energy storage approach is very compatible with a solar air heater.

    Description: Exergy destruction associated with the operation of a solar heating system is evaluated numerically via an exergy cascade. As expected, exergy destruction is dominated by heat transfer across temperature differences. An energy analysis is also given for comparison of exergy cascade to energy cascade. Efficiencies based on both the first law and second law of thermodynamics are calculated for a number of components and for the system. The results show that high first-law efficiency does not mean high second-law efficiency. Therefore, the second-law analysis has been proven to be a more powerful tool in identifying the site losses. The procedure used to determine total exergy destruction and second law efficiency can be used in a conceptual design and parametric study to evaluate the performance of other solar heating systems and other thermal systems.

    Description: A solar power plant suitable for earth orbits passing through Van Allen radiation belts is described. The solar-to-electricity conversion efficiency is estimated to be around 9 percent, and the expected power-to-weight ratio is competitive with photovoltaic arrays. The system is designed to be self-contained, to be indifferent to radiation belt exposures, store energy for periods when the orbiting system is in earth shadow (so that power generation is contant), have no moving parts and no working fluids, and be robust against micrometeorite attack. No electrical batteries are required.
