Abstract: A thermodilution catheter has electrodes in electrical contact with the blood flowing adjacent to the catheter. A potential difference applied to the electrodes causes electrical current to flow in the volume of blood in the region of the electrodes, thereby creating a bolus of blood at elevated temperature suitable for measurement of blood flow by the thermodilution principle.

Abstract: An apparatus for the automatic release of passenger protection devices in motor vehicles in the event of an accident has a sensor (35) having a mass (10) secured outside the center of mass (11). This mass (10) generates a comparably high torque in the suspension in the event of both positional change and rotational acceleration. These torques are detected with known measuring methods and split, with the aid of a high-pass filter (36) and a low-pass filter (40), into a high-frequency and a low-frequency portion. The high frequency portion corresponds to the rotational acceleration, from which the rotational velocity is obtained by means of an integrator (38). The low-frequency portion corresponds to the position of the motor vehicle. Thus both measurement variables that must be detected for releasing a roll bar are obtained with a single sensor (35).

Abstract: To provide an unambiguously representative signal responsive to the speed of a vehicle wheel, an inductive pick-up (1a. . . . 1n) is coupled to a suitable star wheel or the like of each one of the wheels, the pick-ups then providing their signals to amplifiers (3a. . . . . 3n) having hysteresis characteristics. At low speeds, an offset signal is superimposed on the voltage from the inductive pick-ups so that the amplifiers respond and provide output signals only at higher amplitudes of the pick-up signals, thereby eliminating inaccuracies or disturbances occurring in the sensor which might simulate changes in speed of the respective wheel.

Abstract: A bracelet assembly for carrying identification information. The bracelet assembly has an elongated flexible band with fastening means for fastening the band in a closed loop fashion around a patient's limb. There is a transparent portion on the flexible band through which the user can read the identification information. A permanently deformable layer is interposed between the transparent portion and a base layer. The base layer and permanently deformable layer are of contrasting colors. The permanently deformable layer is deformed by lines of force applied by mechanical pressure means such as a typewriter or credit card imprinter which deforms the deformable layer along the lines of force which correspond to the identification information. This renders the base layer visible through both the transparent portion and the permanently deformable layer along the lines of pressure.

Abstract: A robot joint has a support carrying a rotary robot arm. An electric drive motor is mounted on the support and its drive shaft is coupled to the robot arm by harmonic drive-type reduction gears. The reduction gears include an elastically deformable, externally toothed ring whose elliptical shape is rotated by the drive shaft. The externally toothed ring itself is stationary and is firmly connected to the support by a flexible sleeve provided at its free end with a rigid mounting flange. The annular mounting face of the flange and the opposite mounting face on the support is each provided with radial teeth, preferably in the form of Hirth-type gears, which guarantee an accurate centering of the sleeve and safeguard the same against turning. Preferably, the flange is fastened to the end face of a steel bushing which is pressed into a bore in the support and secured against turning by knurled serrations.

A mechanism for preloading and interlocking the base and the platform is also provided. The mechanism includes a shaft passing between the platform and the base and two channels formed in the platform. Elements disposed in the channels urge the shaft in opposite directions or selectively locking and disengaging of the platform and the base.

Abstract: A tire pressure sensor for motor vehicles comprises a pressure switch which is actuated by the tire pressure for monitoring the tire pressure. The pressure switch has a reference pressure chamber which is closed in the direction of the tire by means of an electrically conducting diaphragm and carries a contact pin which is contacted by the middle area of the diaphragm in order to close an electric circuit when there is sufficient air pressure in the tire. In order to trigger an alarm signal during a leak in the reference pressure chamber a leakage check of the reference pressure chamber is realized in that an air gap is located between the contact pin and the middle area of the diaphragm when there is equal pressure on both sides of the diaphragm.

Abstract: An arm splint with a hand receiving portion formed on the forward end thereof includes upper and lower layers which are detachably secured together at the rearward ends and which are integrally secured together at the forward ends through a fold in the material of the device. Conventional retaining bands extend between the layers to hold the arm splint to the forearm of the patient. A separate elongated slot is formed between the two layers adjacent the forward ends to receive the support arm of a selected thumb and finger support element. A pin is provided in an aperture extending through the slot member for detachably holding the support arm of the thumb and finger support element within the slot. Each support arm has one or more apertures for receiving the pin.

Abstract: The commutating poles of vehicular-type d-c motors, for example for trolley buses or trolley cars, are made by winding, on edge, a copper strip, permitting the wound copper strip to resiliently, spring-like expand so that the individual spiral loops thereof will be slightly spaced from each other, and then exposing the copper strip in a fluidized bed to an insulating powder, for example polyethylene or polyurethane, which is subsequently cured in a hardening or sintering process.

Abstract: To determine the optimal location for a magnetic field sensor in a navigational system in a vehicle, the field sensor is preliminarily and releasably secured at a first location in the vehicle, and then the vehicle is rotated by 360.degree., for example by moving it in a circular course. An evaluation circuit is connected to the field sensor which determines the maximum or minimum value of the entire field vector (H.sub.x, H.sub.y). The level of the disturbance field (Hs.sub.x, Hs.sub.y) is determined by carrying out the calculation by adding half of the respective maximum and minimum values in the respective vectorial directions. The steps are then repeated with a different location of the sensor and, when a minimum disturbance field is determined, the sensor can be secured to the vehicle.

Abstract: In a fuel injection system with an acceleration enrichment and a deceleration leaning, in which the transition compensation is determined by means of the throttle valve change speed in connection with the throttle valve change path. By means of the measurement of the throttle valve position the cause for the change of the air quantity is determined so that the information concerning a change of the operating state is present more quickly and a fuel leaning or fuel enrichment can accordingly also be effected more quickly. An intermediate injection threshold, which activates an intermediate injection calculation when exceeded, is built in, in addition, for the acceleration enrichment.

When the volume of product quantities is too large it is compressed, wherein bulky portions of the product break; when the volume is too small, a small quantity of product is added to the main quantity. In addition, an addition device (52), which supplies addition articles (53), is assigned to the conveying device.

Abstract: Device for injecting of fuel into internal combustion engines with an injection jet is provided with a stretched tension wire as a locking spring element for an outwardly opening valve locking member. The pretension of the tension wire is influenced by the current flow in an electrical current circuit which is fed to an electric resistor element being installed into the injection jet. The resistor element may be formed by the tension wire itself or by coil of an electromagnet, whose anchor is coupled with the tension wire. Thus, the opening pressure (P.sub.o) of the injection jet or the injection process can be controlled in a simple manner or may be formed accurately in accordance with a predetermined principle.
