Abstract: A condenser (13) is connected to an outlet of a compressor (10). An expansion valve (16) is connected to the condenser (13). An evaporator (17) is connected between the expansion valve (16) and an inlet of the compressor (10). A sensor (21) detects a condition of refrigerant at an outlet side of the evaporator (17). A variation in rate of refrigerant flow into the evaporator (17) is detected. A control device (22) determines a variation in the detected condition of refrigerant which occurs in response to the variation in the rate of refrigerant flow. The control device (22) judges a quantity of refrigerant to be insufficient when the determined variation in the refrigerant condition is equal to or smaller than a reference value.

Abstract: The binders can be used in particular for formulating corrosion- resistant single-layer coatings having excellent decorative properties. A water-insoluble, film-forming polyhydroxy component with or without phosphoric acid groups is mixed or partially condensed with a water-soluble polyester component whose salt-forming groups are present in the form of phosphoric acid groups attached in the manner of a ester in an amount to correspond to at least 0.1, preferably 0.2 to 2.0 mol of phosphorus per 1000 g of polyester component. Following addition of a crosslinking component from the group of the amino resins or phenolic resins or blocked polyisocyanates or epoxy resins, the resulting resin combination is converted into water-thinnable form by neutralisation of acid-functional groups.

Abstract: Modern infrared radiation detectors have a coverage angle of up to 180 DEG . Such a wide coverage angle is not always required, since interfering sources which are located outside the area under surveillance are occasionally detected in its peripheral area. The new radiation detector is intended to enable simple restriction of the coverage angle and can be adapted, if necessary, to changing conditions. 
<??>According to the invention, a detector casing (1) is provided with a frame (5), in which a guide channel (7) is formed which is suitable for the accommodation of a closable covering element (6). The covering element (6) can be pushed in front of an optical system (3) so that the coverage angle ( alpha 1) of the latter is reduced to a coverage angle ( alpha 2). 
<??>The invention is preferably employed in passive infrared detectors which are used for area surveillance.

Abstract: Accelerations due to excitation of the natural modes of an aircraft's body are suppressed by an active suppression system. Dedicated accelerometers are positioned in the aircraft at optimal locations for sensing modal induced lateral accelerations. The accelerometer produced signals are processed through control logic which, in response thereto, and in response to aircraft velocity and altitude related signals produces output control signals. The control signals effect rudder deployment creating forces to suppress the natural mode induced accelerations.

Abstract: A fibrous substrate having a first coefficient of thermal expansion and having porous characteristics is formed from discrete elements, such as carbon fibers, having anisotropic properties. A matrix formed from a refractory material encases the discrete elements and has a second coefficient of thermal expansion different from the first coefficient. The matrix has minimal chemical or mechanical bonding to the discrete elements to provide for a displacement of the matrix relative to the substrate with mechanical shock or changes in temperature. The matrix includes a first element having refractory properties and selected from the group consisting of hafnium, zirconium, tantalum, tungsten and molybdenum also includes a second element bound to the first element. The matrix is preferably formed by providing a mixture of a first gas containing the refractory element and a second gas containing the second element and by introducing the gases into a chamber containing the substrate. The gases are introduced into the chamber at an elevated temperature and with a pressure pulsating at a particular rate between first and second pressure limits to obtain the deposition of the refractory material on the discrete elements. The gases are periodically exhausted from the chamber and fresh gases are introduced into the chamber. The matrix may consist of first and second layers respectively having hafnium (e.g. hafnium carbide) and zirconium (e.g. zirconium carbide) as the refractory materials. These layers define pores with the   substrate and further define an external surface. A layer of rhenium may cover the matrix in the pores and in the external surface.

Abstract: A memory routing scheme for a computer system having M processors (P0 ... P5) and N memories is described. M processors are coupled through a randomizer (23) to a routing network (10), such as a crossbar. The crossbar is coupled to N memories (MEM 0 ... 5). When a memory address is specified by a processor, it is acted on by the randomizer and a routed address is given to the memory. The memory having the routed address is coupled to the processor for the access. By utilizing a random routing scheme, the memories are not optimized for any one particular access mode, but present the same look to the processors regardless of the access mode. The average number of collisions in this scheme is a function of the number of memories, number of processors and number of access ports. In one embodiment, a hashing table is utilized for the assignment of the routing address to the memories. Alternatively, a randomizing function is utilized to generate a routing address.
