Patent EP-0568127-A2 (EP)
Inventor: YUAN YI
IPC: G10K11/178
Filed: 1993-04-05
Abstract: An active noise control (ANC) system for attenuating engine generated noise containing at least one sinusoidal noise component having an amplitude and frequency varying with changes in engine rotational speed includes means (200-204) for generating at least one generator output signal containing one or more sinusoidal signal components, the frequency of each component corresponding to the frequency of a respective noise component. A separate control signal having an amplitude varying with engine rotational speed is generated to correspond with each generator output signal. Each generator output signal is multiplied by its respective control signal to produce a corresponding filter input signal. Each filter input signal is filtered through a respective adaptive filter (206-210) to produce a corresponding filter output signal according to the adjustable filtering characteristics of the adaptive filter. Noise cancelling waves are generated by a noise cancelling actuator (28,32,36) in response to each filter output signal and superimposed on the noise. The level of residual noise following superposition is sensed and an error signal developed to represent the residual noise level. The filtering characteristics of each adaptive filter are adjusted based upon the error signal to minimize the residual noise level. Each control signal has its amplitude determined a respective predetermined function based upon the sensed engine rotational speed and each predetermined function is correlated with the amplitude behaviour of the noise components corresponding to the signal components contained in the generator output signal multiplied by the respective control signal.

Abstract: A shock absorbing disconnect latch comprises a lever, a wall for limiting travel of a longitudinal channel, and at least one vertical slot in a downwardly sloping body to enable rearward flexing of the disconnect latch for removal of the longitudinal channel. The flexing of the disconnect latch causes the lever to move counterclockwise providing space for the longitudinal channel to be disengaged. The flexing of the disconnect latch permits easy removal of the longitudinal channel, together with reliable return of the lever. When the longitudinal channel is stopped by the wall of the disconnect latch, the shock energy is absorbed using the slot by deflection of the disconnect latch.

Abstract: A coupling assembly includes a receiving tubular member (13) defining an opening (27) for receiving a first tubular member (12). The receiving tubular member has an inner portion defining an inner bore dimensioned to receive one end (68) of the first member, and an outer portion defining an internal annular cavity (22) intersecting the inner bore and projecting radially outwardly therefrom. The annular cavity (22) comprises an annular tapered wall portion (25) tapered radially inwardly and projecting longitudinally toward the opening (27), and a split lock ring (72) formed from spring material and disposed in the annular cavity between the first tubular member (12) and the receiving tubular member (13). The lock ring (72) has an outer circumferential surface portion adapted to engage the tapered wall portion (25), and an inner circumferential surface portion (73) adapted to engage an external wall portion of the first tubular member (12). The lock ring (72) is adapted to expand circumferentially into the annular cavity (22) during insertion of said first tubular member into the receiving tubular member, and to be compressed between the tapered wall portion and the external wall portion in response to relative longitudinal separating movement between the first tubular member and the receiving tubular member. The inner circumferential surface portion (73) of the lock ring defines first and second substantially parallel, spaced apart, circumferentially extending knife edges (76, 81). Also included is an annular sealing member (36) disposed in the annular cavity between the lock ring and the inner bore, the sealing member being dimensioned to be engaged between the first tubular member and the receiving tubular member. Under high pressure conditions both of the knife edges (76, 81) penetrate the external wall portion so as to prevent longitudinal movement of the first tubular member relative to the receiving tubular member.

Abstract: A current source (70) is coupled to supply an output current to a circuit node (60) proportional to a video input signal (R). A first resistor (65), coupled between the circuit node (60) and a source of supply voltage (68), develops an amplified video signal which is coupled from the circuit node to the cathode (K1) of a kinescope (20) via a second resistor (85). A capacitor (100 or 110) is provided having a first electrode coupled to the cathode (K1) of the kinescope (20) and having a second electrode coupled to the circuit node (60) via an amplifier (90). Advantageously, the combined resistance of the two resistors (65 and 85) imparts gamma correction to the kinescope (20), the capacitor (100) and amplifier (90) compensate for stray capacitance associated with the cathode (K1) without subjecting low frequency components to any possibility of distortion in the amplifier (90). Additionally, the capacitance (110) may be varied as a function of the beam current for stabilizing the overall driver amplifier frequency response.

Abstract: The appts. to fit cord handles to tote bags has a section (15,16) to clamp the edges of the bag together with a punch (20) to stamp holes in the bag edges. A feed (19) guides the cord between the stamped holes for the cord ends to be knotted (17,18). At least the feed (19) for the cord (3) is at the clamping unit or can be positioned at it. Controls operate the punch stamping and cord feed alternately. Also claimed is an operation where the appts. is passed over the bag edges for them to be clamped. The punch is activated to stamp holes in the bag edges and a guide channel for the cord is formed between the two knotting units (17,18), giving an exact positioning of the stamped holes and the cord guide (19). An air stream carries the cord through the first module (17) and the first punched hole, through the guide channel (19) and through the second punched hole to the second knotting module (18). A cutter severs the cord (3), and the free cord ends are clamped at the knotting modules (17,18). The cord guide channel (19) is moved away from the knotting modules (17,18) to tense the knots and pull them clear of the modules (17,18). The two half sections of the cord guide (19) are opened, to release the cord handle loop. <IMAGE>
