Patent EP-0357999-A2 (EP)
Inventor: SYDOW FRIEDRICH-WILHELM DR STA
IPC: A61M25/06
Filed: 1989-08-12
Abstract: The kit for intrapleural regional anaesthesia consists of a needle (10) which has at one end a needle connector (11) and at the other end a partly ground central opening (12), of a mandrin which fills the lumen of the needle (10) and of a catheter (30) which can be displaced lengthwise in the needle (10). The needle connector (11) is releasably connected to a Y tube piece (20) which is equipped at the end of its tubular part (21), which is coaxial with the needle (10), with a sealing catheter junction (24, 25, 40) and whose branching-off tubular part (28) is in open connection with a non-deformed collapsible rubber bulb (32). The rubber bulb (32) serves as a detector to indicate that the pleural cavity (15) has been reached, by contraction under the influence of the lower pressure prevailing in the pleural cavity, where the sealing catheter junction (24, 50, 40) on the tubular part (21) which is coaxial with the needle (10) prevents the introduction of outside air into the channel system of the set both when the catheter (30) is inserted and without the catheter. The result of this is that use of the set for pleural analgesia is more straightforward for the user and safer for the patient. <IMAGE>

Abstract: A method for automatically calibrating gain parameters of a servo control including a track position detector for a computer disk drive. The method generally comprises the step of encoding AB bursts on at least one special calibration track of a disk surface in accordance with a known off center pattern signal having a preselected frequency. Servo correction number information is also encoded on the calibration track to compensate for the off center pattern of the AB bursts. A digital signal processing technique is performed on a correction signal derived from the AB bursts and servo correction number information to detect a residual signal at the preselected frequency of the off center pattern signal. The gain of the track position detector is thereafter adjusted to minimize the magnitude of the residual signal.

In order to easily identify a pattern of time-series state changes based on measured information so as to facili­tate representation of edge portions of an image, features ex­tracted in form of expansion coefficients of polynomials from the measured information are translated into abstract expres­sions so as to derive from the measured information signi­ficant control information. Features extracted in form of ex­pansion coefficients from brightness changes in the vicinity of each pixel constituting image data are also translated into abstract expressions.

Abstract: A hydraulic pressure control valve (56) regulates the operational pressure in response to a valve operating force. The operational pressure is applied to the hydraulic clutch (12c, 13c, 14c). The operational timing of the control valve is adjusted by control means (80,82.84) in response to a detection of a condition immediately before engagement of the hydraulic clutch. 
     The operating force is set to maximum at first during shifting. It is reduced to a low value when the above condition is detected so that the operational hydraulic pressure is reduced to a pressure a little lower than engagement starting pressure at which the hydraulic clutch is kept in a condition immediately before engagement. Then, it is increased to a specified value when an input to output speed ratio becomes approximately 1.0 so that the operational hydraulic pressure is increased to a specified pressure at which the hydraulic clutch is engaged.

Abstract: An electrical connector is formed of electrically conductive traces supported on an insulating plastic support. Vias are provided through the support so that the traces are supported over the via openings in at least two positions. Most typically, the vias have parallel opposing edges, and the traces are supported across the via opening from the opposing edges. This connector design containing vias permits two types of improvements in use. First, the doubly supported traces are resistant to misalignment, and are more readily bonded to bonding points on a component, as compared with singly supported, cantilevered traces. Second, the connector can be more readily bent over angularities on the surface of a component when a via is placed in registry with the angularity, because the bending of the traces is not constrained and the overall stiffness of the connector is reduced so that less force is required to bend the connector over the angularity.

Abstract: A hydrophilic porous membrane is obtained by covering porous membrane substrate with a non-ionic, amino-acid-based or non-ionic fluorine-based surface active agent. For the covering, the porous membrane substrate is immersed in a solution containing the surface active agent and then drying the membrane substrate. A different hydrophilic porous membrane is obtained by providing the surfaces of a porous membrane substrate and inner pore surfaces with a polar group and then covering the membrane substrate with a hydrophilic polymer film. For this covering, after introduction of the polar group to the surfaces of the porous membrane substrate and inner pore surfaces, the membrane substrate is immersed in a solution containing a hydrophilic substance and then dried. In a liquid filter using any of these hydrophilic porous membrane, the porous membrane is disposed in a housing such as to divide the housing inner space into two sub-spaces respectively communicating with a liquid inlet and a filtrate outlet provided on the housing.

Abstract: Light is condensed on a recording medium (20) by an objective lens (11), and light reflected from the recording medium passes through the objective lens and is split into light along two optical paths (P,5) via a condenser lens (5) and beam splitter (6). A light-receiving surface (7) having an area smaller than that of the irradiation pattern of the returned light when the objective is focused is disposed on the inner side of a focal point on one optical path, and an identical light-receiving surface (8) is disposed on the outer side of a focal point on the other optical path. The arrangement is such that the photoelectric outputs of the two light-receiving surfaces (7,8) coincide when the objective lens (11) is focused. Preferably, the light-receiving surface is divided into four portions by a straight line, which is obtained by projecting the track direction of the recording medium, and a region having line symmetry with respect to the straight line and an area smaller than that of the irradiation pattern when the objective is focused. A tracking error signal of the objective lens (11) is obtained by correcting a difference signal between light-receiving surfaces on the inner side by a low-frequency component of a difference signal between light-receiving surfaces on the outer side.

Abstract: The driving arrangement, which is suitable in particular for a lifting device, contains a reversible pole 3-phase motor which can be combined with a friction brake, that can be raised by an electromagnet (27), to form a structural unit. The two three-phase field windings, dimensioned for different numbers of poles, are connected in a star circuit and have star points (5, 9) which are led out at the motor terminal box (3) of the three-phase motor. The electromagnet (27) of the friction brake is connected to the star points (5, 9) via a rectifier circuit (29) and, when the three-phase motor is switched on, is energised by the differential voltage occurring in this case between the two star points (5, 9) in order to raise the friction brake. Together with a controllable switch (31), likewise connected to the two star points (5, 9), the rectifier circuit (29) is housed in the motor terminal box (3), the switching path (33) of the controllable switch short-circuiting or isolating the electromagnet (27) on the DC side when the three-phase motor is switched off. The friction brake of the driving arrangement can in this manner be controlled from a remotely located switch box, containing a directional contactor (15, 17) and a speed contactor (19), without any additional connecting lines being required for this purpose in addition to the connecting lines (9, 11) which are required in any case to operate the three-phase motor. In a corresponding manner, the arrangement is also suitable for three-phase motors connected in a delta circuit.
