Abstract: An ash tray having fire protecting activity and comprising an ash tray body (2) including an ash container (24) and an internal or external time delay circuit which is connected to an acoustic and/or optical alarm and supervising means. The ash tray is formed with a lid (3) which is normally intended to be closed, whereby the time delay circuit (25) and any other units connected thereto are disconnected but which upon opening of the lid actuates the time delay circuit, whereby the time delay circuit provides an alarm signal unless the lid (3) is closed before a predetermined set time delay has passed to an end. The lid (3) preferably is actuated by a spring (16) which tends to open the lid and against the action of which the lid can be closed, whereby the time delay circuit (25) and the alarm means connected thereto are reset. The ash tray may include a cigarette lighter (32) which is covered and non-actuatable when the lid is closed but which is exposed and can be actuated when the lid is opened.

Abstract: A flight recorder (11) for a vehicle such as an airborne vehicle is provided in which various data is recorded, along with on-board time data (from 38) in order to be processed by ground based equipment (13). The on-board time data is synchronized by using a telemetry signal (DT) which is received by a ground based tracking system so that the timing of the events recorded by the flight recorder (11) may be synchronized with the timing of events recorded by the ground based tracking system. This combined data is provided to the ground based equipment (13) in order that the data at (12) obtained on-board the vehicle can be analyzed. By the use of digital techniques, various measurements, such as acceleration and angular rate may be accurately stored and reproduced. This arrangement reduces repeat costs for multiple tests and increases reliability of test data.

Abstract: A device is disclosed for testing the resilience of a game ball. The device comprises a tubular member having an opening at one end for receiving a game gall to be tested. A striking surface on the other end of the tubular member and calibrated markings along the length of the tubular member indicate the degree of resiliency of the game ball by virtue of the distance the game ball rebounds from the striking surface when the ball is dropped from the opening.

Abstract: An element firmly connected with the drive shaft of an injection pump is locked in a predetermined rotary position, corresponding to the supply onset, by a locking device before the mounting of the injection pump to the associated internal combustion engine, the locking being effected by means of a holding bolt embodied as a reversible part. The holding bolt, locked by a fastening means in a reception bore, engages a transverse groove on the end face, in a first mounting position, via a protrusion on the element firmly connected with the drive shaft, and thus establishes a form-locking connection which keeps the drive shaft in the predetermined rotary position. In a second mounting position of the holding bolt, where the transverse groove points outward, the rotary movement of the drive shaft is unhindered.

Abstract: A permanent magnet is mounted on a rotary member via a non-magnetic holder which magnetically and thermally insulates the magnet from the rotary member. This prolongs the life of the magnetic and obviates noise outputted by a stationary pickup which is excited by the magnet passing thereby.

Abstract: A method in which a plug-in pump, controlled by oblique edges, is inserted with the aid of an adjusting device into a pump fitting of an internal combustion engine and which without subsequent correction of the supply quantity guarantees an identical supply quantity for all the plug-in pumps of one engine. With a supply quantity adjusting member held firmly in a test position, the plug-in pump is inserted into the test pedestal and rotated until such time as the supply quantity corresponds to the set-point supply quantity, this rotational position marked by a slash mark on the flange of the plug-in pump. With a governor rod, which is part of the engine, locked in the basic test position, a second slash mark is subsequently made on the pump fitting by means of a dummy pump. Once the dummy pump has been removed, the plug-in pump is secured in the pump fitting of the engine with the slash marks in alignment.

Abstract: A method and apparatus for determining the injected fuel quantity in internal combustion engines having self-ignition are proposed. A performance graph is prepared which includes the injected fuel quantity per stroke in accordance with the injection duration, with the rpm as a parameter. In order to avoid a fictive 0 point, the injection duration is shortened by a predetermined period of time and multiplicatively linked with an rpm signal, while linear rpm correction curves having a dependency of the rpm voltage on the injection duration can be assumed. At the output of an integrator by means of a sample and hold circuit, an injection quantity signal is produced whenever the rpm signal (Un) is supplied to the integrator for the integration process and the duration of the integration is determined on the basis of the injection duration signal (SD).

Abstract: A device for the scanning of objects by means of ultrasound echography comprises a first ultrasonic transducer (10) which is connected to a transmitter stage (50) for the repeated transmission of ultrasonic signals and to a receiver stage (100, 200) for receiving the ultrasonic echoes which correspond to the most important obstacles encountered by the tramsmitted signals in their propagation direction, said receiver stage comprising a first, known processing circuit (100) and, connected parallel thereto, a second processing circuit (200) which consists of a series connection of a control circuit (210) for the automatic control of the gain as a function of the distance of the echoes, a correction circuit (220) for the correction of transducer diffraction effects, a selection circuit (230) for the selection of a narrow frequency band within the pass-band of the transducer which is centered around a frequency F.sub.

Abstract: Apparatus for simulating varying levels of friction in the bearings 13 of a free rolling tail afterbody 11 on a canard-controlled missile 12 to determine friction effects on aerodynamic control characteristics. A ring 16 located between the missile body and the afterbody is utilized in a servo system to create varying levels of friction between the missile body and the afterbody to simulate bearing friction.
