Patent EP-0117910-A1 (EP)
Inventor: EFRON EDWARD
IPC: G11B27/36
Filed: 1982-09-14
Abstract: Method and means for evaluating the quality of audio and/or video transfer characteristics of a device upon which, or through which, audio and/or video information is contained, or passes, respectively. Both method and apparatus concern the evaluation of the quality of information transfer in the recording and playing back of a recording medium or in the transferring of audio and/or video information through an information handling device referred to as a throughput device. Unit evaluation is accomplished by establishing an input signal of known content, measuring selected parameters of selected parts of the input signal, feeding the input signal to the unit under test, measuring the parameters of parts of the output signal from the unit under test corresponding to the same selected parts of the input signal, and comparing the selected parameters of the input signal with the corresponding parameters of the output signal. Whether monitoring the quality of the signal transfer characteristics of a throughput device, a magnetic tape containing program material, or a video disc, master disc or replica, a "signature" is created for the unit under test, and subsequent analysis of the unit as it progresses along a production line or of a copy made on the same or alternate recording medium results in a second "signature" which is compared against the first signature to make a determination as to the quality of the signal handling or transfer characteristics of the unit. In this manner, out-of-tolerance conditions can be automatically detected, thereby eliminating subjectivity and providing consistency in the quality level of device testing.

Abstract: An improved apparatus for cutting hair includes a pair of panels which are pivotally interconnected for movement between an open position in which the panels are spaced apart from each other and a closed position in which major sides of the panels are disposed in a side-by-side relationship. Each of the panels has a nonlinear pattern edge portion which is used to guide a haircutting device, such as scissors or a razor or clippers, along a nonlinear path. The pattern edge portions of the two panels have the same configuration with crests projecting outwardly away from base edge portions of the panels and troughs between the crests. In order to comb the hair and retain it against sidewise movement along the pattern edge portions, a large number of bristles extend outwardly from a major side of one of the panels. The hair is laid across the bristles when the panels are in the open position. The other panel is then clamped against the bristles to hold the hair.

Abstract: Un système de contrôle d'un paramètre de moteur, par exemple la pression d'huile, qui varie en fonction de la vitesse du moteur, contrôle ce paramètre par rapport à une valeur supérieure et à une valeur inférieure. La pression d'huile est détectée par un transducteur (122) et la pression détectée est contrôlée par une paire de comparateurs (252, 266) comparant la pression d'huile détectée avec les tensions de référence correspondantes aux valeurs supérieures et inférieures. Les tensions de référence peuvent être modifiées sélectivement par un commutateur (124) afin de changer les valeurs prédéterminées de pression. Les sorties des comparateurs (252, 266) commandent un indicateur (16) qui réagit lorsque la pression contrôlée est inférieure à l'une des valeurs prédéterminées. Un circuit (75) est prévu pour empêcher l'actionnement de l'indicateur (16) par le comparateur (252) contrôlant la pression par rapport à la valeur supérieure lorsque la vitesse du moteur est inférieure à une valeur prédéterminée. La sortie du comparateur (266) réglant la pression par rapport à la valeur inférieure commande un compteur horaire de service (18) afin d'indiquer le temps qui s'est écoulé pendant que le moteur tournait.

Abstract: Band-rejection filter of the switched capacitor type in which at least one unwanted frequency component present in an information signal must be suppressed. To that end this filter comprises an adder circuit 4 to which the information signal is applied via a switching device 3 and a feedback signal via a switching device 5. Both switching devices are controlled by a first control signal consisting of a sequence of control signal periods of a duration T<sub>s</sub> which are each divided into a tracking phase and into an interrupt phase. During the tracking phase the signal can pass uninterruptedly through the switching device, while during the interrupt phase signals are not allowed to pass. The output of adder circuit 4 is coupled inter alia via a switching device 8 to the input of a bandpass filter 9 whose passband at least coincides with the unwanted frequency component. The switching device 8 is controlled by a second control signal which is also formed by a sequence of control signal periods of a duration T, and which are each divided into a tracking and an interrupt phase.In order to realize an adequate suppression of the unwanted frequency component the instants at which the tracking phases in the first control signal and the tracking phases in the second control signal end are mutually phase-shifted over a fixed distance.

Abstract: @ The conical pre-sealing ring (30) is intended to provide temporary sealing while the appliance (20) is being screwed into or unscrewed from the valve (10) of a gas cylinder. 
     Deep penetration of the push-element (21) of the appliance (20) can cause the conical pre-sealing ring (30) to reverse and remain in this position, even after unscrewing. 
     According to the invention, to overcome this drawback, the conical pre-sealing ring (30) is provided with radial protuberances (33) which prevent gas-tight contact between the reversed surface of the conical pre-sealing ring (30) and the valve shoulder (16). This ensures that the space (40) always remains in communication with the gas pressure, so that, on dismantling, the sealing ring is returned to its initial position by a purely pneumatic effect.
