Method for distribution control of drum type washing machine before drying clothes

The invention discloses a method for distribution control of a drum type washing machine before drying clothes, which comprises a speed at the beginning of water drainage stage, a low rotating speed of clockwise and anticlockwise rotation in the water drainage stage, a medium rotating speed after a rapid rising state through high-speed rotation in one direction and a high rotating speed after a slow rising stage in the direction identical to the direction of the previous stage. The amount of unbalance is judged after the high rotating speed is stable. When the amount of unbalance is larger than or equal to the amount of weight unbalance set in a program, the rotating speed is reduced to the low rotating speed in the water drainage stage, and the distribution is performed again from the second stage 5-6 seconds later, and if the pulse conditions can not satisfied after continuous distribution for three times, the distribution is performed again from the first stage. If the amount of unbalance is smaller than the amount of weight unbalance, the pre-hydrating and drying can be directly performed. The control method of the invention not only can achieve the best clothes distribution effect, thereby reducing the damage to the drum caused by displacement and centrifugal force resulting from uneven distribution, but also can greatly reduce the time before main drying and simultaneously save the electric energy.

Algae culture agent for aquaculture

The invention relates to an algae culture agent for aquaculture, and belongs to the technical field of aquaculture. The algae culture agent is prepared from potassium fulvic acid, sodium metasilicate, ammonium sulfate, sodium humate, monopotassium phosphate and a beneficial algal solution. The algae culture agent is prepared by weighing the materials according to ratios, uniformly stirring and mixing the materials into paste, and packaging the paste, thereby obtaining the algae culture agent for aquaculture. The raw materials selected for the algae culture agent are dissolved in water at constant speed, so that the phenomenon that a pond substrate is corrupted by insoluble raw materials settled to the bottom of a pond is avoided. Meanwhile, after the sodium humate is dissolved in water, a certain water color appears, so that slow growth of algae can be controlled, and the phenomenon of stress to an aquatic animal due to rapid rise, which is caused by rapid growth of the algae, of the pH of the pond is avoided. Furthermore, the beneficial algal solution in the algae culture agent can be multiplied preferentially after obtaining proper nutrition, so that the amount of beneficial algae is effectively increased, and multiplication of harmful algae is inhibited; therefore, a better guarantee is provided for aquaculture success.

Methods and apparatus for recording impulsive sounds

Loud sounds with fast rise times, like gunfire and explosions, can cause noise-induced hearing loss (NIHL). Unfortunately, current models do not adequately explain how impulsive sounds cause NIHL, which makes it difficult to predict and prevent NIHL on battlefields and other hostile or rugged environments. Fortunately, the impulsive sounds experienced by soldiers and others working in rugged environments can be recorded using a compact, portable system that acquires, digitizes, and stores high-bandwidth audio data. An example of this system can be mounted on a helmet or other article and used to record hours of audio data at a bandwidth of 20 kHz or higher, which is broad enough to capture sounds with rise times less than 50 ms. An analog-to-digital converter (ADC) digitizes these broadband audio signals at rate of 40 kB / s or higher to preserve the impulse information. A processor transfers the digitized samples from a buffer to a memory card for later retrieval using an interrupt-driven processing technique.

Slowly digestible starch-containing foodstuffs

InactiveUS20070082109A1High reduction in GISlowly digestibleDough treatmentPreservation by heat treatmentDiseaseDigestible starch
The invention relates to slowly digestible starch-containing foodstuffs, such as cereals and snacks, while a substantial percentage of the starch phase of starch-containing foodstuffs is transformed into a slowly digestible form in situ during foodstuff manufacture by modifying the method typical for the respective foodstuff, and if necessary, the recipe. During the manufacture of starch-containing foodstuffs, the starch is most often prepared to the extent where it digested exceedingly quickly, and converted into glucose in the process. This leads to a rapid rise in the blood sugar level (high sugar), followed by a speedy to severe drop in the blood sugar level (low sugar). These foodstuffs have a high glycemic index (GI). A high number of more recent studies suggest that foodstuffs with a high GI are a significant cause of diabetes, obesity and cardiopulmonary diseases. The WHO believes that indicating GI values on foodstuff packaging would effectively help in preventing the mentioned diseases. Therefore, there is a need for starch-containing foodstuffs that have a reduced GI, i.e., are slowly digested. Within this context, the ideal scenario involves a foodstuff with a constant hydrolysis over time, wherein precisely the amount of glucose consumed for metabolism is released per unit of time. Such a foodstuff would be exceedingly desirable in particular for diabetics. The best currently existing solution for diabetics in this regard is uncooked, i.e., native corn starch (WO 95 / 24906), which is digested relatively slowly. However, the consumption of native cornstarch in the form of an aqueous slurry is unattractive on the one hand, and only a limited time-constant release of glucose can here be achieved on the other. In addition, the temperature stability of native cornstarch is limited, so that only very limited incorporation in processable foodstuff preparations is possible. Other forms of slowly digestible starches include resistant starches (e.g., high corn, Novelose, ActiStar, CrystaLean). These starches exhibit a high crystalline percentage, and about 50% can be digested in the small intestine. The remainder is fermented in the large intestine. The percentage that can be digested in the small intestine is predominantly digested very quickly, so that it makes sense to use only a limited amount of resistant starches as food additives for reducing the GI. Other slowly digestible starches are described in WO 2004 / 066955 A2. These starches are obtained by gelatinizing a suspension of about 5% starch in water,
