    Abstract: A gyrocompass including a first gimbal, a gyro motor mounted in the first gimbal and including a gyro rotor mounted to rotate about a horizontally alignable spin axis, a pendulous body in which the first gimbal is mounted to be rotatable about a vertically alignable axis of rotation, a housing in which the body is rotatably suspended, a verticality device associated with the body for allowing the body to assume an orientation in the housing in which the axis of rotation is vertical, and a follow-up device including a pickup mounted for sensing the angular position, about the axis of rotation, of the gimbal relative to the body and a drive connected for rotating the body relative to the housing about the axis of rotation in dependence on the position sensed by the pickup. The drive can be constituted by a stepping motor constructed to rotate in highly uniform steps and simultaneously serving to provide an indication of the angular position of the body relative to the housing about the axis of rotation. Alternatively, the drive can be constituted by a stepping motor constructed to rotate in highly uniform steps, the follow-up device can include a restraining circuit and a torquer connected between the pickup and the first gimbal for restraining the first gimbal at a defined angular position, about the axis of rotation, relative to the body, the restraining circuit providing a signal representative of the angular velocity of the first gimbal about the axis of rotation, and the gyrocompass can further include a unit for determining the direction to true north from signals representative of the angular velocity.

    Abstract: Defects in the sealings of closures are located and measured by rotating the sealed closure and directing a light beam to the sealed area. The light beam reflected from the sealing mass is compared to a prespecified rated value and any deviation resulting from the comparison results in actuation of an ejecting device for ejecting the defective closure from the testing station.

    Abstract: The invention relates to a process for the preparation of 1,5-dihydroxyanthraquinone and 1,8-dihydroxy-anthraquinone and of their mixtures. Alkali metal salts or alkaline earth metal salts of the corresponding anthraquinonedisulphonic acid are treated, in an aqueous medium under pressure and at elevated temperatures, with lime, buffer substances and, if appropriate, oxidizing agents, a surface-active agent is added to the resulting reaction mixture and the mixture is then acidified in a continuous process with mineral acid at temperatures of 50.degree. C to 150.degree. C and a pressure of 1-3 bars, and the dihydroxyanthraquinone which has precipitated is isolated. Compared to the known procedure, the process according to the invention is distinguished by a substantially improved space-time yield with at least equal purity of the reaction products.

    Abstract: A blood glucose sensing system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes stabilization circuitry. The stabilization circuitry causes a first voltage to be applied to one of the electrodes for a first timeframe and causes a second voltage to be applied to one of the electrodes for a second timeframe. The stabilization circuitry repeats the application of the first voltage and the second voltage to continue the anodic-cathodic cycle. The sensor electronics device may include a power supply, a regulator, and a voltage application device, where the voltage application device receives a regulated voltage from the regulator, applies a first voltage to an electrode for the first timeframe, and applies a second voltage to an electrode for the second timeframe.
