Title: Method and apparatus for air temperature regulation
IPC: F23N1/02
Filed: 1965-12-22
Abstract: In a pulverulent fuel fired furnace, the heater 3 for the secondary air fed to the furnace and the heater 9 for the primary air fed to the pulverizers 18 are arranged in parallel in a gass pass 7. The proportion of hot and cold primary air fed to each pulverizer 18 and the total air flow through each pulverizer are controlled by dampers 25, 24 and 32 and a selecting controller 35 adjusts the total primary air damper 39 to maintain the most nearly open pulverizer damper 32 in a preselected nearlyopen position. A damper 12 controlling the amount of flue gas flow through the primary air heater 9 is adjusted by a selecting controller 43 to maintain the most nearly closed cold primary air damper 25 in a predetermined nearly closed position. The mean of the cold primary air temperature and the cooled flue gas temperature at the exit of air heater 9 is used to regulate the operation of heater 9 to prevent corrosion by passing steam through a heating coil 54 in the primary air heater supply conduit, or by feeding part of the primary stream through an air heater by-pass to mix with the hot primary air stream, or by changing the preselected position of the chosen pulverizer cold air damper 25 to enable hotter primary air to be used.

Patent ES-355502-A1 (ES)
Title: Starting aids
IPC: F23Q7/00
Filed: 1968-06-19
Abstract: To prevent the fuel tank 7 of a fuel-injection I. C. engine from fully emptying, with consequential occurrence of air locks in the fuel system, a float-operated valve 1 located in the tank obstructs the outlet from the tank if the level in the tank falls below a predetermined level, whereby flow of sufficient fuel to permit continued running of the engine is prevented, so that the engine stops. A controlled leakage of fuel may be allowed, either through the valve or through a small by-pass bore, so that the vacuum occurring in the fuel system after the engine has been stopped is gradually removed, thereby reducing the risk of air leakage into the fuel system through imperfect joints. The vacuum may be used to actuate a piston 49 to close down the fuel injection pump 43 by means of the rack 45. Instead of a piston 49, a solenoid controlled by a vacuum switch may be used, and the vacuum switch may also control a solenoid-operated stop cock located upstream of the pump 43. The stop cock may instead be operated through a diaphragm by the difference in pressure between a point in the fuel line 11 adjacent the stop cock and a point adjacent the valve 1.

Patent ES-389570-A1 (ES)
Title: Machining of workpieces by electro-erosion
IPC: B23H1/02
Filed: 1971-03-25
Abstract: The energizing circuit of an electro-erosion system, connected across an electrode and a workpiece to be machined, comprises a source of alternating current with an operating frequency of up to 5,000 Hz from which an unbroken succession of voltage pulses is obtained by means of a full-wave raw-rectification circuit. A reactance common to both branches of that circuit, such as an inductance effectively in series therewith, maintains a residual potential difference across the erosion gap as the driving voltage of the source goes to zero, resulting in continuing ionization of a substantially stationary dielectric liquid in the gap to increase the service life of the electrode by limiting the amplitude of the current pulses.
Patent ES-395520-A1 (ES)
Title: Synchronizing system
IPC: H04N5/12
Filed: 1971-07-29
Abstract: A vertical phase synchronization system for a television receiver develops vertical deflection frequency signals by employing a resetable frequency divider circuit to count down clock pulses having a frequency twice the horizontal deflection frequency. The resultant internally generated vertical signals are compared with received external vertical synchronization signals. If a phase error exists, a pulse width detector to which external sync pulses subject to noise are applied, is activated. When activated, the pulse width detector develops a reset pulse for the frequency divider to lock the phase of the internally generated vertical signals with external vertical sync in response only to a pulse of the requisite vertical sync pulse duration, thereby providing noise immunity for the system.
Patent ES-412344-A1 (ES)
Title: Devices for sensing deviations from a horizontal plane
IPC: G01C5/04
Filed: 1973-03-05
Abstract: A device for sensing deviations from a horizontal plane is disclosed, which device includes a pair of spaced chambers interconnected by a tube which allows liquid to flow from one chamber to the other as the position of the device varies with respect to the horizontal plane. A metal float is provided in each chamber and above each float there is a sensor of the proximity type. Transistor oscillators, the outputs of which vary upon approach of a float, form suitable sensors. A metal rod runs through the tube and is pivotally mounted at the centre of the tube. The floats are secured one adjacent each end of the rod and the rod thus prevents both floats from lifting simultaneously. Electrical signals from the sensors, which signals indicate a deviation from the horizontal plane, are fed to drive means such as an electric motor which operates to tilt the device back to the horizontal position.

Title: Procedure for control of processor overload
IPC: H04M3/36
Filed: 1977-09-13
Abstract: The work load of a computer in a data processing system is periodically regulated in such a way that the maximum permissible load to be processed in a given time interval is a function of the instantaneous occupancy level of the computer. Such a method of regulation may be applied to a processor-controlled telephone switching system in which it is desirable to control the load conditions since if the processor(s) is or are overloaded, then the service which the system provides deteriorates. The overload conditions are controlled by ensuring that in each of a number of successive time intervals only N new calls will be accepted, any new calls above the number N thus being deferred to the next time interval. This number N, and possibly also the duration of the time interval, is periodically up-dated in accordance with the current traffic conditions. Thus a dynamic technique for the control of the overload in achieved.

Title: Deviation detector for AC signal - has switching circuit delivering signal when DC component is at either max. or min.
IPC: G01R19/165
Filed: 1977-10-31
Abstract: The detector senses any deviation of an a.c. signal from a specified characteristic. The a.c. signal is applied to a circuit that delivers a signal when the d.c. component is at either a max. or min. This signal is completely outside a stationary signal area during a specified min. period, or when the a.c. component is at a min. and the peak-to-peak signal amplitude falls below a specified min. value during a specified min. period. Once a signal is delivered it can be suppressed only on reception of an erasing signal. The switching circuit can comprise an a.c./d.c. signal AND gate (3) with two inputs (1, 5). An a.c./d.c. converter (7) follows the gate (3) and has its output connected to the d.c. input (5) of the AND gate (3).
