Patent ES-468118-A1 (ES)
Title: Solar heat collector - with reflectors consisting of two intersecting part circles of specified configuration
IPC: F24S10/70
Filed: 1978-03-21
Abstract: A solar heat collector consists of parallel blackened copper tubes for water circulation which are housed in reflectors embedded in heat storing material. Each reflector has a cross-section of two intersecting parts of two circles of the same radius as the diameter of the copper tube. The centres of the two circles lie on the copper tube in a plane parralel to the transparent front plate. This ensures that the solar radiation is either directly or by multiple reflection directed to the copper tube surface, independent of the angle of the solar radiation as it varies through the day. Every brief appearance of sunshine is thus utilized.

Patent ES-8302074-A1 (ES)
Title: Process for heating coal-oil slurries.
IPC: C10G1/06
Filed: 1982-01-28
Abstract: Controlling gas to slurry volume ratio to achieve a gas holdup of about 0.4 when heating a flowing coal-oil slurry and a hydrogen containing gas stream allows operation with virtually any coal to solvent ratio and permits operation with efficient heat transfer and satisfactory pressure drops. The critical minimum gas flow rate for any given coal-oil slurry will depend on numerous factors such as coal concentration, coal particle size distribution, composition of the solvent (including recycle slurries), and type of coal. Further system efficiency can be achieved by operating with multiple heating zones to provide a high heat flux when the apparent viscosity of the gas saturated slurry is highest. Operation with gas flow rates below the critical minimum results in system instability indicated by temperature excursions in the fluid and at the tube wall, by a rapid increase and then decrease in overall pressure drop with decreasing gas flow rate, and by increased temperature differences between the temperature of the bulk fluid and the tube wall. At the temperatures and pressures used in coal liquefaction preheaters the coal-oil slurry and hydrogen containing gas stream behaves essentially as a Newtonian fluid at shear rates in excess of 150 sec -1. The gas to slurry volume ratio should also be controlled to assure that the flow regime does not shift from homogeneous flow to non-homogeneous flow. Stable operations have been observed with a maximum gas holdup as high as 0.72.

Title: Modulation system for railway circuits.
IPC: B61L1/18
Filed: 1984-01-13
Abstract: A modulation system for railway track circuits in which a modulated signal is applied to a section of track for the purpose of detecting the presence or absence of a train on the section. Such circuits are used to control signalling and they are vital to safe operation of a railway. At a transmitter end, the output (19) of a power amplifier (18) is connected to a section of track. The power amplifier (18) receives the modulated signal from a modulator (17) which is itself controlled by a pseudorandom binary sequence generator comprising a clock (11), a shift register (10), and a modulo 2 adding circuit (13, 14, 15). Equivalent circuitry is used at a receiver end to recognize the pseudorandom sequence in the absence of a train on a given section of track. The likelihood of interference from a train on that section generating an interference signal capable of being mistakenly recognized for the absence of a train can be reduced to an arbitrarily low value.
