Abstract: Abstract A low actuation pressure bar vent  for use  in a tool string having  low pressure therein.   The vent includes a body portion and a piston slidingly disposed in the body.          The piston and body define a first cavity therebetween and a second cavity therebetween,  spaced from the first cavity.          The body further defines a plurality of  transverse ports therethrough providing communication between a body central opening and a well annulus.  When in a closed position, the piston sealingly closes the ports.   In a first embodiment, the first cavity has a spring disposed therein. The body also defines a second plurality of ports therein providing fluid communication between the first cavity and the well annulus.   Pressure in the well annulus and the spring bias the piston toward an open position uncovering the ports.  In an  alternate  embodiment,  a  pressurized  gas  biases  the piston.  The second cavity is filled with a fluid such that movement of the piston is prevented.  A break plug is posi-tioned in the piston and includes a shearable portion, which when sheared, allows the fluid in the second cavity to be released to the tubing string.  The biasing force moves the piston to the open position, displacing the fluid from the second cavity.  During assembly, an assembly plug holds the piston closed.

Abstract: A preparation for rehydrating monogastric animals, including humans and newborn ruminants who/which are suffering from diarrhoea, which preparation is intended to be mixed in water, comprises a water-binding swelling agent, electrolytes and (a) lactose-cleaving enzyme(s), and, where appropriate, fillers, taste corrigents and dyes. The swelling agent constitutes 20-70% according to weight, preferably 40-43%, the electrolytes constitute 40- 60% according to weight, preferably 53-57%, and the enzyme or enzymes constitute(s) 0.01-5% according to weight, preferably 0.025-0.027%, and the remaining quantity consists of fillers, taste corrigents and/or dyes, with a filler preferably being wheat bran. It has been found to be particularly advantageous for the swelling agent to be plant fibres from the family Plantaginacea, and for the enzyme to be lactase having a pH optimum of between 2 and 10, and for the electrolytes to be a mixture of 2 or more of the substances magnesium oxide, citric acid, potassium chloride, sodium citrate, sodium chloride, sodium bicarbonate and glucose. An optimal effect is achieved when the fibres are dried, crushed seed husks from Plantago ovata. This results in a composition for rehydrating diarrhoea- affected animals, which can be cured within the course of a very few days, with fatalities and weight loss being avoided. The vast majority of cases of non-infectious diarrhoea in single-stomach animals can be cured in a very few days.

Abstract: For ventilating a floor in a building, air is made to flow in a ventilation space 6 between a subfloor 1 and an upper floor 8. The air drawn into the ventilation space is taken at a temperature which exceeds that prevailing in the ventilation space or at floor level, preferably by being drawn in at roof level. The relative humidity is measured in the air being drawn out of the ventilation space, which is drawn off by a fan 31. When the optimum relative humidity falls below a given threshold value, the capacity of the fan is kept at a given constant and low level. If the measured relative humidity exceeds the threshold value, the capacity of the fan is kept at a higher value, for as long as the measured relative humidity lies above the threshold value. Heat exchange takes place between outgoing air and fresh air drawn into the building. <IMAGE>

Abstract: The invention relates to a method and/or a device for demodulating a binary coded phase-modulated signal (biphase signal). It is provided to determine the period of time (T) passing between each two successive level jumps of an incoming biphase signal, to generate or extract a clock frequency (B) approximately corresponding to the bit rate of the biphase signal with the aid of a clock generator, the clock period (1/B) of which clock frequency is compared with the period of time (T) between each two level jumps, and to determine the logical value of the biphase signal with the aid of an interrogating circuit controlled by the clock frequency (B), and to output a signal corresponding to the logical value, whenever a value of between 1/4 and 3/4 of 1/B was determined twice in succession for the period of time (T) immediately before, or whenever a value of between 3/4 and 5/4 of 1/B has been determined for the period of time (T) immediately before. In addition, a signal identifying a disturbance can be output or the output can be muted if a value of less than 1/4 of 1/B or greater than 5/4 of 1/B has been determined as the period of time (T). The invention makes it possible to recover the original data with sufficient reliability in a relatively simple manner when a biphase signal is present.

Abstract: The device for calculating the tariff, preferably intended for an electricity meter, exhibits a microprocessor (1), a data memory (6) and a bidirectional interface (8) for data transmission with a reader. A timing section (9) is activated for the duration of a data transmission and, via a logic circuit (10) blocks a predetermined storage area (6a) against being loaded with data. The data stored in the storage area (6a) and used for accounting purposes are thus protected against unintentional changes during the data transmission even if the software has corresponding errors. The function of the timing section (9) and of the circuit (10) can be checked in a simple manner. Objections with respect to the data security during a bidirectional data transmission are thus without substance. The device for calculating the tariff is therefore suitable for calibration.
