Abstract: Abstract of The Disclosure A known powered air-purifying respirator has an alarm that is preset to be actuated whenever a Pitot static sensor indicates that the airflow has dropped below a safe level.  The invention permits such a respirator to be used with either a tight-fitting facepiece or with a loose-fitting hood or helmet and, without adjusting the preset alarm, can indicate that the airflow has dropped below the proper minimum for whichever is being used.  This is accomplished by supplying the respirator with two breathing tubes, a first of which is unobstructed and can be fitted only to a loose-fitting hood or helmet that requires high airflow.  The other breathing tube can be fitted only to a tight-fitting facepiece and has a protuberance that reduces the cross-sectional area of the chamber in which the Pitot static sensor is mounted so that the alarm is actuated only when the airflow drops below a level that is lower than the alarm-sounding level when the first breathing tube is being used.

Abstract: An analog digital conversion is provided for two color difference signals, for example for a recording according to a timeplex method. The color difference signals are adjusted in their amplitude at the input of the analog digital converter such that the modulation range of the analog digital converter is always fully used independent of the original amplitude of the color difference signal. The amplitude is restored back to its original value after a digital to analog reconversion. This results in an improvement of the signal to noise ratio during the transmission. The amplification provided to the various signals can be controlled by comparator circuits comparing the signal level with a reference signal.

Abstract: A method of processing cattle feed products based on agricultural material, such as sugar beet pulp, citrus fruit pulp and peel, and material obtained in the fermentation of agricultural material, such as distiller's grain, which material is available after either a fermentation process or sugar leaching of beet pulp or after mechanical dewatering (pressing) or evaporation. To improve the nutrient value and general quality of the cattle feed product while at the same time improving the heat economy of the production process the invention proposes a method comprising the steps of preheating the material in steam, known as carrier steam, disintegrating the material in said steam for fragmentation thereof into uniform particle size, and drying the material particles in heat exchangers. Preferably the carrier steam is a part of the drying medium used in the process, that is, for heating and conveyance of the particles. The cattle feed processing steps may be performed in the order indicated or processed in any other suitable order. The cattle feed product/material is then separated from the carrier steam and cooled. The plant designed to perform the method includes a pressure vessel (5) to which moist cattle-feed material (1) is transported via a pressure lock (4), equipment (8, 10) for disintegration of the material to equalize the particle size, equipment (11) for drying the material and a pressure lock (14, 15) to discharge and separate the material from the carrier steam.
