Patent ES-353121-A1 (ES)
Title: Dc motor speed control for operation over a wide range of supply voltages
IPC: H02P4/00
Filed: 1968-04-24
Abstract: Apparatus such as a shaver or toothbrush is driven by an electric motor 2 adapted to be supplied from direct voltage sources having differing magnitudes, the motor being rated for the lowest value of said voltages. A control device is located in the casing of the apparatus and transmits rated power to the motor despite changes of the supply voltage. In one arrangement, the armature of the motor 2 is shunted by a resistor 6 in series with capacitor 5, and when the voltage across the capacitor increases so that the Zener voltage of diode 8 is exceeded, a voltage is developed across resistor 9 to operate a transistor 10. Transistor 12 then becomes conductive to render the switching transistor 4 non-conductive until the capacitor voltage decreases and the diode 8 is blocked. The motor thus receives a pulsating current, the pulse duration being dependent upon the source voltage. Diode 7 prevents voltage peaks due to the switching operation, and capacitors 14, 15 steepen the slope of the pulsating D.C. supply.

Filed: 1968-05-07
Abstract: A fuel module forming part of the core or blanket of a breeder reactor comprises a shell 11 of hexagonal cross - section having an inlet 12 and outlet 37 for liquid sodium coolant, the coolant flowing through tubes 21 connected between lower and upper end plates 14, 22. The fuel is in the form of a slurry consisting of particles of plutonium dioxide and uranium dioxide in a fluidizing medium of liquid sodium and is initially admitted through a pipe 33. The fluidizing medium maintains an expanded bed 40 of fuel between a distributer plate 24 and a level control screen 30, this medium being kept in circulation and leaving through a pipe 36. Movement of the fluidizing medium through the expanded bed 40 is made possible by providing clearance spaces around the tubes 21 in their passage through the plate 24 and intermediate baffles 27. The baffles serve to prevent circulation of the bed 40 and thus enable an axial temperature gradient to be formed in the module. The fuel may be discharged by applying fluidizing medium to an inlet 34.

Title: Hoist system
IPC: B66C1/34
Filed: 1977-09-15
Abstract: In a load system which involves a powered chain hoist wherein raising or lowering of a load is effected by a rotating drive sprocket over which the chain is trained, the amplitude of motion due to resonant response of the load system as a consequence of coincidence between the natural frequency of the load system and the frequency of oscillatory excitation produced by the chain/sprocket drive is significantly reduced by providing an energy dissipation device in series with the load. This device involves a spring mechanism which permits a limited motion at the resonant condition, in combination with a controlled damping factor. The spring compliance of the device normally will lie in the range of about 1/2-3 times the spring compliance of the active length of the chain at the resonant condition and the relation between the spring rate of the device and the effective damping factor is perferably such that the spring rate divided by the damping factor will be at least about 0.006 seconds. The device so tuned is also effective in rapidly attenuating the amplitude of the transient motion induced when the hoist is suddenly stopped or started.

Title: Unloading
IPC: B02C2/04
Filed: 1978-09-08
Abstract: In the case of overloading of a gyratory crusher the manometer 14 detects a mean effective pressure of the hydraulic fluid in the cylinder 7 greater than a first limiting value, which causes the opening of the maximum pressure valve 18. The hydraulic fluid then flows into the hydraulic accumulator 22, previously filled with a gas at a pressure substantially equal to the said first limiting value. When the overloading is terminated, the maximum pressure valve 18 re-closes and the hydraulic fluid returns by the return branch 24 into the pressure chamber of the cylinder 7. In the case of very substantial overloading capable of damaging the apparatus, the manometer 26 causes the opening of the safety valve 29.
