Patent ES-407076-A1 (ES)
Title: Electronic system and method for capsule inspection
IPC: B07C5/342
Filed: 1972-09-27
Abstract: An electronically controlled system and method for processing the signals obtained from an optical inspection of rapidly presented and rotated medicinal capsules. Built-in deviations in the capsule structure are differentiated from structural defects which may occur and the decision made to accept or reject each capsule. The occurrence of a defect or a built-in deviation causes photo detectors to have a current spike output. Both the defect and the built-in deviation spikes are converted to digital pulses. The defect pulses are counted and the deviation pulses are used to reset a free-running oscillator controlled counter. A defect in the circumferential vicinity of the built-in deviations causes the built-in deviation counter to be prematurely reset. This causes a defect to be recorded. Each capsule is redundantly examined. A sufficient number of reoccurrences of any defect causes a shift register to be activated which initiates and controls the rejection of the capsule. Optical readouts present the number of rejected and accepted capsules, and the percentage of rejected capsules for each lot of 1,000 capsules which are inspected.

Title: Anti-lock vehicle brake systems
IPC: B60T8/1763
Filed: 1975-04-30
Abstract: An electronic control circuit for an anti-lock vehicle brake system which includes apparatus responsive to an input signal having a quantity which is a function of wheel speed to produce an output signal for causing energization of a solenoid valve when the quantity undergoes a change corresponding to a change in wheel speed at a rate in excess of a first predetermined rate of change of wheel speed and by an amount which is greater by a given percentage than its amount of change would have been had its change of wheel speed continued at said first predetermined rate of change. The latter corresponds to a reference rate of wheel deceleration. Other apparatus responsive to the input signal when the output signal is produced to store an initial reference velocity signal that has a predetermined relationship with the actual wheel speed to which the value of the quantity then existing corresponds. Other apparatus is responsive after a predetermined period for producing a generated signal following the initial storage of the reference velocity signal. The generated signal corresponds initially to the reference velocity signal but then decreases at a second predetermined rate of change of wheel speed greater than the first reference rate of wheel speed and for a variable period whose duration is a function of the initially stored reference velocity. This apparatus is responsive following the variable period for then increasing the generated signal at a third predetermined rate of change of wheel speed until it attains a predetermined value having a given relationship with the initially stored reference velocity. This apparatus is also responsive following the attainment of the predetermined value by the generated signal to decrease the latter at a fourth predetermined rate of change of wheel speed. Additional apparatus is responsive to the input signal for terminating the output signal to cause solenoid de-energization whenever the quantity assumes a value corresponding to a wheel speed having a given relationship with the prevailing value of the generated signal.

Title: Water pump seal wear measurement - using optical device mounted in discharge pipes to show datum mark movement
IPC: G01B11/02
Filed: 1977-02-03
Abstract: The pump which circulates water in a water cooled nuclear reactor has a rotor (6) mounted on a shaft.
