Abstract: In printing devices which are to print automatically readable script in particular great value is placed on an entirely accurate and clearly readable printing script because otherwise the reading devices recognize erroneous characters or the documents are rejected. In order to produce easily readable characters and in order to increase the life of the corresponding type wheels it is proposed either to move the document (8) by means of a step motor (SM) with micro-step control (MP, D/A.sub.1, D/A.sub.2, V.sub.1, V.sub.2) and to arrange the characters, which are to be arranged flush right or flush left, according to convention, in the center (FIG. 2A) and to bring about the flush right or flush left printing by means of the micro-step control. In addition, it is suggested, according to the invention, to also control spoke type wheels (1) with different pitches by means of a type wheel drive motor (M) provided with a micro-step control (MP, D/A.sub.1, D/A.sub.2, V.sub.1, V.sub.2).

Abstract: The proposed plug-in connection provides that the wheel revolution counter itself or its free end, respectively, are constructed as a plug-in connection part with exposed contact paths, the wheel revolution counter being fastened e.g. at a rim of a vehicle wheel, and the counterpart of the plug-in connection provided e.g. in a hand-held device serving for the data take-over. Reciprocally acting catch members and the contacts which latter are assigned to one another, are constructed in such a way that it is possible to connect the wheel revolution counter and data take-over device regardless of position and in such a way that a reciprocal rotation is enabled which serves for making contact.

Abstract: A mounting or carrier for data communications units configured as hand-held units suitable for heavy duty in a motor vehicle, and which permits simple handling of the hand-held units and affords a high functional security as far as the line connection and attachment is concerned. A head pin or lug is mounted to a flange surface on the carrier or support, which engages a keyhole-like aperture in the hand-held unit. A flexibly supported guidance part projects from a console molded at the carrier and cooperates with a recess in the hand-held unit. The electrical line connection points of the carrier are shielded by the guidance part when no hand-held unit is present thereon, and the guidance part additionally functions for actuating a switch.

Abstract: A vehicle information apparatus for recording, computation and display of data ascertainable from the driving performance of a motor vehicle. The apparatus includes a transmitter module for providing data concerning a trip, a central unit with internal program and data memories and a display device. The vehicle information apparatus is coupled with the operating mechanism of a radio cassette set for playback of data information stored on an audio data carrier. The transmitted data are separated in a signal input and output stage of the apparatus, stored and displayed. The audio data carrier is repeatedly loaded with topical information and serves particularly for the distribution of instructions prior to the start of a driver's shift in a taxi or transportation vehicle fleet.

A dual sleeve assembly is arranged within the tank having an inner sleeve with a lower end in fluid-tight connection with the tank and an outer sleeve arranged to define an annular space between itself and the outer wall of the tank and an intermediate space between itself and the inner sleeve. Fuel is introduced into the tank through an aperture so as to flow into the annular space between the tank wall and the outer sleeve and then to pass through the intermediate space so as to overflow the inner wall and to flow into an interior space of the tank within which the float is located.

Abstract: An arrangement is described for the selection of a tariff level "n" by repeated actuation of a key T1 or T2, which can be actuated in series, whereby the desired tariff level is adjustable by forward switching or reverse switching. Each selected tariff level is displayed immediately after detecting the key actuation by an allocation sentinel (27) in a display (10), and the start of a waiting time, which can be preset, can be triggered in each tariff selection. After the expiration of the waiting time, a parameter assigned to the last selected tariff level appears in the fare display field (26) and, accordingly, signals the acceptance of the last selected tariff level including the activation of all of the rest of the parameters assignable to the selected tariff level. It is possible, thereby, to select a tariff level by skipping over undesired tariff levels without the fare display being changed during the selection process.

Abstract: A method and arrangement for providing a continuous visual check on the operation of a standard liquid crystal display by superimposing a checking signal upon the operating signals applied to the individual segment and back electrodes of the LCD through individual impedance paths substantially higher than the individual impedance paths carrying the operating signal to the segment and back electrodes so that the operating signal overrides the checking signal under normal circumstances but the checking signal overrides the operating signal when the latter is interrupted due to a fault. The checking signal causes the segment electrode or back electrode whose signal is impaired to blink at a visually perceptible rate. Preferably, the frequency of the checking signal is in the order of 0.5 Hz to 2.0 Hz.
