Title: Method and device for controlling periheral speed of plurality of wheel of railway rolling stock
IPC: B60T8/66
Filed: 1978-06-28
Abstract: PURPOSE: To control slip of wheels to the predetermined and optimum slip in accordance with running speed by reducing driving force for a wheel which slips lastly and increasing friction force between the wheel and a rail when reaching a slip amount that all the wheels cannot permit. CONSTITUTION: Wheel peripheral speeds v1 to v4 detected by sensors G1 to G4 are compared with an evaluation reference value v from an element F taken out from the signals in comparison elements k1 to k4, and difference signals [Delta]v1 to [Delta]v4 are output to logical elements V1 to V4 through controllers R1 to R4. Moreover, when all wheel speeds v1 to v4 are increased above the evaluation reference value, a selection circuit L judges a wheel which slips lastly from the minimum value of the difference signals [Delta]v1 to [Delta]v4 based on the difference signals [Delta]v1 to [Delta]v4 to turn on the logical elements V1 to V4 by corresponding signals from output terminals L1 to L4, to reduce driving force on the wheel which slips lastly through operation parts MV1 or MV2 to MV4, and to increase friction force between the wheels and a rail by sand. Consequently, it is possible to control slip of wheels to the predetermined and optimum slip by corresponding to running speed.

Title: Machine for assembling screw blanks and washers
IPC: B23P19/08
Filed: 1979-03-05
Abstract: A machine for assembling washers on headed screw blanks, comprises a turntable having peripheral recesses into which the washers are inserted. Elevators in the form of vertically swinging arms are mounted on the turntable about the periphery thereof, extending generally radially of the turntable, and are cam controlled to swing vertically relative to the turntable. In their upwardly swung position, recesses in the outer ends of the arms receive screw blanks beneath the heads thereof, the arms then swinging downwardly to insert the screw blanks in the washers that are in alignment below the screw blanks on the turntable. At the discharge side of the turntable, a slideway is provided for complete assemblies but incomplete assemblies are detected and are disassembled with the parts returned to storage. Incomplete assemblies are diverted along a pair of spaced horizontal rails that extend tangentially of the turntable and have opposed grooves that receive the washers, the heads of the screws riding on the upper surfaces of these rails. The slideway for the complete assemblies is horizontally swingable, under control of a detector of incomplete assemblies, into vertical registry over the pair of rails, whereupon the incomplete assembly is dropped from the slideway onto the rails, the rail grooves terminating sooner than the upper surfaces of the rails, so that the washers drop off the incomplete assemblies before the screw blanks drop from the rails, thereby to separate the washers from the screw blanks of the incomplete assemblies.

Title: Method and apparatus to control a blending installation for textile fibres.
IPC: D01G7/00
Filed: 1981-07-10
Abstract: A method of, and apparatus for, checking a plant for blending textile staple fibres of different types, which are supplied by fibre metering units. The supply of fibres to the storage device is interrupted during repeated time intervals. According to the invention the fibres supplied by an individually operated fibre metering unit, supplying a constant quantity, during part time intervals within the time intervals are transported to a quantity measuring device and are measured. The present invention permits very reliable and precise checking of the fibre quantities supplied by the fibre metering units in such a manner that a desired blending proportion can be maintained precisely. The machines fed from the storage device can be maintained operating during the checking periods, i.e. at all times. The checking operations thus can be effected within relatively short time intervals in such manner that deviations from a pre-set desired value are detected early and that also relatively short-term deviations can be detected.

Patent ES-8503436-A1 (ES)
Title: Method for the ultrasonic measuring of the relationship between the volume of gas present in an enclosure containing a liquid-gas mixture end the total volume of the enclosure.
IPC: G01H5/00
Filed: 1983-02-08
Abstract: The invention relates to a method of ultrasonic measurement of the ratio of the volume of gas present in an enclosure containing a diphase liquid-gas mixture to the volume of the enclosure, or void coefficient. Waves at different frequencies are propagated through the fluid filling the enclosure (1). The propagation times of the waves are measured and the difference between these propagation times is calculated. If the propagation times are identical, it is deduced that all the gas is in the form of a layer surmounting the liquid. The void coefficient is determined from the propagation velocities of the ultrasounds in the gas and the liquid and from the measured propagation time. If the propagation times are different, a part of the gas is in the form of bubbles in the liquid, the void coefficient due to the gas surmounting the liquid and the void coefficient due to the gas bubbles in the liquid are determined separately. The total void coefficient is determined by adding the two values obtained. The void coefficient due to the gas surmounting the liquid may be determined by virtue of the waves reflected by the gas-liquid interface. The void coefficient due to the gas bubbles is determined by virtue of the relationships existing between the velocity of the ultrasounds and the frequency of the waves, according to the pressure and the void coefficient. The invention is applicable to the measurement of the void coefficient in a pressurized water nuclear reactor after an accident.

Patent ES-8501885-A1 (ES)
Title: Apparatus and method for measuring the filterability of a fluid.
IPC: G01N11/06
Filed: 1983-08-31
Abstract: A cold box (12) has a temperature regulating mechanism (14) connected thereto. In the cold box a filter holder (24) is connected between first and second cylinders (26 and 28). The filter holder has a housing in two parts held together by a quick attachment and release mechanism (34) which permits a calibrated filter to be inserted and removed easily. The first cylinder (26) contains a free piston (50) which separates a quantity of fast fluid from a pressurized inert gas (56) which is supplied to an opposite side of the piston. The pressurized gas forces the fast fluid through the calibrated filter to the second cylinder (28) where it impinges on another free piston (66). This free piston is biased by gas pressure (pressure regulator 84) so that back pressure is created across the filter to simulate actual conditions which would occur in a full-size device, such as an engine. The rate of flow at a given temperature is measured by a flow meter (78) or by measuring the time for a predetermined volume of test fluid to be displaced (calibrated indicator rod 68 fixed to piston 66).
