Title: Circuit de detection de charge dans une soupape de commande de direction sensible a la charge
IPC: E02F9/22
Filed: 1985-05-13
Granted: 1993-01-13
Abstract: Circuit de détection de charge dans une soupape de commande de direction sensible à la charge (16A) comprenant un dispositif (55A) servant à détecter des signaux de pression de charge, à identifier ces signaux de pression de charge comme étant positifs ou négatifs et à transmettre ces signaux de pression de charge identifiés comme étant positifs ou négatifs aux organes de commande de compensation d'étranglement (16B) de la soupape sensible à la charge, tout en transmettant à la commande de la pompe (13) le signal positif de pression de charge. L'identification et la distribution des signaux de pression de charge aux commandes (16B) du circuit sensible à la charge peuvent avoir lieu lorsque le distributeur de commande de direction (19) se trouve dans sa position neutre. Ce circuit de détection et de transmission de pression de charge peut par conséquent anticiper la fonction de commande indiquée par le signal de commande.

Abstract: A coupling sleeve (3) pushed onto the plastic pipe (1) and provided with barbs (3a) is drawn over a driving shoulder against the connecting piece (2) by a union nut (4). The opened-out pipe end (1a) is clamped between a curved end face of the connecting piece (2) and the coupling sleeve (3). Possible leakages caused by the flow of the pipe material are prevented by a spring (6), and the pipe (1) is prevented from turning during assembly by a sliding ring (5). The device used for assembling the pipe connection has grips (13) for fixing the pipe in position with a toggle lock (16) and a press ring (26), which can be displaced in sliding manner on a stop (25) acting as a centering arbor, and can be actuated by a hand lever (31). With only a few manipulations, the coupling sleeve (3) can be pushed onto the centrally held plastic pipe (1). Owing to the omission of the supporting sleeve required hitherto, the through-flow cross-section of the plastic pipe (1) is not reduced by the installation of this pipe connection. Heating up the end of the plastic pipe is no longer necessary during assembly. The pipe connection, which can be made cost effectively, is uncomplicated in its construction and absolutely liquid-tight.

Abstract: The present invention refers to a method for controlling the vertical adjustment of a levelling and compacting plank drawn by a road-construction machine. During the working procedure the level of the plank, which is in floating contact with the material, is adjusted automatically. The present invention aims at preventing undesirable lifting of the plank caused by material which is located ahead of the plank and the flowability of which was changed due to an interruption in the motion of the machine. Hence, the invention employs the feature that, when the travelling mechanism is switched on, lifting of the plank, which is blocked against lowering when the machine is standing still, is blocked as well and that the blocking is eliminated only after a predetermined period of time.

Abstract: A pipe wrenching tool adapted to be powered by a hand held power drive mechanism is formed with a support for a drive wheel and an idler wheel with the idler wheel being movable with respect to the drive wheel to adjust the tool for differing sizes of pipe. The tool is adapted to interface transversely to the axis of the pipe to be wrenched with the drive wheel engaging the pipe without requiring a part of the tool to circumscribe the pipe. The rotational axis of the idler wheel and rotational axis of the drive wheel are off-set with respect to each other to cause the pipe being wrenched to be forced into the tool. The tool is adapted at both sides to have the drive source attached at the side of the tool away from the pipe so that the tool may be used to engage and wrench pipe in confined spaces. Only the wheels of the tool are rotated; the tool need not rotate with respect to the pipe.

Abstract: The disclosed invention is for use in extracting more accurate information from signals employed in pulse oximetry. Basically, pulse oximetry involves the illumination of arterial blood flowing in tissue with light at two wavelengths. Upon emerging from the tissue the light is received by a detector (38) that produces signals that are proportional to the intensity of the light received at each of the wavelengths. Each signal includes a slowly varying baseline component representing the attenuation  beta (t) of light produced by bone, tissue, skin, and hair. The signals also include pulsatile components representing the attenuation  alpha (t) produced by the changing blood volume and oxygen saturation within the finger. The signals produced by the detector (38) are converted by an analog-to-dig                      ital (A/D) converter (72) for subsequent analysis by a microcomputer (16). The microcomputer (16) extracts the following information from the signal corresponding to each wavelength. V H is determined to be the signal magnitude at a second pulse diastole. V L is, similarly, the signal magnitude at systole of the same pulse. A term  DELTA V is identified equal in value to the difference in signal magnitudes at the adjacent systoles. Finally, values are determined for  DELTA ts and  DELTA tp, being the interval between an adjacent systole and diastole and the pulse period, respectively. The microcomputer (16) then determines a value for R OS in accordance with the relationship: <MATH> Empirically derived oxygen saturation curves are used to develop an indication of the oxygen saturation from the value of R OS computed.

Each cylinder of the engine is provided with an inlet valve (2) to which the compressor (5) of the turbo-compressor (4) delivers air through an inlet pipe (6), and also with an outlet valve (3) from which gases are passed from the cylinder to the turbine (7) of the turbo-compressor (4) through an outlet pipe (8). According to the invention each cylinder is further provided with a pressure control valve (9) which is connected to the outlet pipe (8) by means of a pressure control line (10), between the outlet valve (3) and the turbine (7) of the turbo-compressor (4). The pressure control valve (9) is intended to open when the piston, during the compression stroke of the engine cycle, is located in the cylinder in a first predetermined position (D) at a distance from the bottom-dead-centre position (C) of the piston, and is intended to close when the piston, during the compression stroke, is located in a second predetermined position (E) at a greater distance from its bottom-dead-centre position. The air flowing through the pressure control line (10) can be heated in a heat exchanger (23) by hot exhaust gases downstream of the turbine (7) such as to recover heat from these exhaust gases.

Title: Method and switching arrangement for the compensation of offset voltages in a focus and/or track-following circuit
IPC: G11B21/10
Filed: 1989-07-13
Granted: 1992-09-23
Abstract: A method for compensating offset voltages selectively in a focusing circuit that focuses a beam from a source of light on a recording medium and in a tracking circuit that positions a beam of light on data storage tracks on a recording medium. A beam of light reflected from the recording medium is directed onto a photodetector which has a plurality of photodiodes. The difference of the output voltages from the photodiodes is taken for generating an error signal which is stored as a reference during a first stage in open or closed state of the circuit selected. The selected circuit is then closed and a compensation parameter is supplied in a second stage to controls in the selected circuit. The compensation parameter is then varied until the error signal is substantially equal to the stored reference. The compensation of the offset voltages is independent of the tracking circuit, and the offset voltages in the focusing circuit can be compensated when the tracking circuit is closed.
