Abstract: A method for combining individual road transport and railway transport with a rapid transfer from the one mode of transport to the other is described. Articulated lorries are used as the transport units of the individual traffic, and only their load-carrying and transportation material-carrying semitrailer is transferred onto the low-level carriage of the railway transport in accordance with a transverse-rolling method known per se. The traction unit only serves as a power unit and supports the docking manoeuvre. After this, said unit is available again for other individual traffic transport duties. The movement energy is supplied by the traction unit to the semitrailer by means of removable current or air lines which are uncoupled after the docking manoeuvre. In order to secure the semitrailer in position on the low-level carriage, blocking devices are provided which can be actuated in self-service mode. Technical means which prevent the low-level carriage from tipping over during the load transfer are provided on the ramp and/or on the low-level carriages. These technical means consist for example of bolts which can be pushed forward on the low-level carriage and engage in corresponding profile strips on the ramp.

IPC: G09G3/28

Abstract: The invention provides voltage potential differences for selectively discharging cells in a plasma display device, with greater brightness and reduced power consumption. The plasma display device has orthogonally related electrodes sealed in an atmosphere of neon gas. When a predetermined potential is applied between two intersecting electrodes, the neon gas glows at the intersection. The predetermined potential is achieved by applying two pulse trains which have opposite phases and therefore oppositely going voltage polarities. The difference in the oppositely going peak voltages of the two pulse trains provides a firing potential at the selected intersection. To decrease the voltage causing an erroneous discharge, a short period of an extinction mode is introduced before an address mode. In another embodiment, to reduce power consumption, the cell at the intersection is fired at a high potential during an address mode and thereafter held in a glowing state by a greatly reduced voltage. Another embodiment produces a similar result by changing the frequency of driving pulses in the firing and the holding modes.

Abstract: An older measuring device (according to EP-A2-0,267,381), in which polarised light is coupled into a fibre optical (LWL) sensor and the change in phase difference occurring in the event of a change in length of the LWL is determined, consists of the following parts connected in series: transmitter, LWL, phase sensor, LWL, receiver and measuring device. This device is to be developed in such a way that it is capable of carrying out an exact determination of measured values. Furthermore, the aim is to specify an alternative cable connection between the phase sensor at the measured object and the measuring device in the control room. The solution consists in that three receivers (71-73) replace the one receiver, the light beam coming from the LWL sensor (4) is subdivided by means of a beam splitter (grid (16) or optical block) in three partial beams (18), and partial beam 1 impinges onto the assigned receiver directly, while beam 2 does so through a  lambda /4 plate (17) and an analyser (52), and beam 3 does so through an analyser (53). Furthermore, instead of the LWL connecting cables, it is possible to use Cu connecting cables (19), the light transmitter and light receiver (1 and 7, respectively) being integrated in the phase sensor instead of in the measuring device.

Abstract: A radio transmitter includes a bank of pre-distortion circuits (8, 10, 12) each of which is selectively connectable between the mixing stages (2) of the transmitter and the final linear power amplifier stage (20) of the transmitter. The pre-distortion circuit to be connected is determined by the RF frequency of the signal to be transmitted. A method of analysing the distortion produced by a linear power amplifier (20) is also described. In this method two tones are applied to the amplifier and the resulting down-mixed signal is subjected to a FFT in order to derive the spectrum and plot the amplitude and phase distortion against the two tone amplitude. Analysis of the results of such testing allows the pre-distortion circuits (8, 10, 12) to be designed to compensate for distortion produced by the amplifier over the complete operating frequency range of the transmitter.

Abstract: An apparatus for casting an agarose gel and for conducting an electrophoresis process is disclosed. An electrophoresis tank (106) supports a gel casting deck (202) having open ends (210) which are sealed by wedge dams (302) to form a cavity for containing the molten agarose as it gels. The wedge dams (302) are pulled downward by gravity into wedge-shaped slots. The weight of the wedge dams (302) in the wedge slots presses the wedge dams (302) against the open ends (210) of the gel casting deck (202) so as to provide a substantially fluid-tight seal. The gel casting deck (202) has sidewalls whcih are slanted toward one another in the upwards direction so that when the gel is submerged in buffer solution during electrophoresis, the gel's tendency to float is substantially impeded. The combs (408) which form wells in the gel are referenced to the sides (208) of the gel casting deck (202) itself so as to ensure uniformity and accuracy of well depth. Safety features prevent the electrophoresis tank from functioning if removed from its protective housing.

Abstract: A data processing system processes a data stream based on the structure of a font file which can be varied by a user or application of the processing system. The font file not only contains the pel patterns for a range of graphical symbols, but it also contains the rules for interpreting a data stream having a particular syntax. The rules for interpreting a data stream are referred to as the processing model for the data stream. 
     The structure of the font file contains an index array to the range of graphical symbols. Each byte in the data stream is used to generate an index into the index array. In each element of the index array there is a value and control bits. The control bits indicate whether the value is an offset to a graphical symbol or whether the value is a modifier. If the value is a modifier, it is used to increment the next sequential data byte in the data stream through the range of graphical symbols. The modifiers can be use recursively to access an unlimited number of graphical symbols.

Abstract: A method of controlling supercharging pressure in an internal combustion engine based on a basic control amount determined in dependence on operating conditions of the engine. The basic control amount is corrected in response to a difference between an actual value of the supercharging pressure and a desired value of same when the engine is in a feedback control region. The basic control amount is corrected in accordance with the change rate of the supercharging pressure when the engine is in an operating condition immediately before the feedback control region. The supercharging pressure is controlled based upon a second basic control amount when the supercharging pressure is below a predetermined value determined by the engine rotational speed and the change rate of supercharging pressure in the above operating condition. The feedback control is started on condition that the actual supercharging pressure has increased above a second predetermined value set depending upon operating parameters of the engine and a parameter representative of an environmental condition of the engine. The feedback control is started when a predetermined period of time has elapsed after the supercharging pressure has increased above the second predetermined value. The feedback control is effected when the supercharging pressure is in a steady state, while the supercharging pressure is controlled in open loop mode when it is in a transient state.

Abstract: The invention indicates on the one hand a method for actuating a heating apparatus, in particular a vehicle additional heating apparatus, in which combustion air and fuel are supplied to a burner, and a flame is produced in a combustion chamber. In this connection, the air ratio, which is significant for the stability of the combustion operation and the harmful substance content emitted, is determined on the basis of the flame temperature measured in the combustion chamber. With a desired value for the air ratio predetermined, regulation is then preferably carried out to the effect that the quantity of combustion air and/or fuel supplied is changed in such a manner that a predetermined desired value for the air ratio and a corresponding desired value for the flame temperature are achieved. Also indicated is a heating apparatus which has in the flame region of the combustion chamber a flame temperature detection device which is associated with a device for determining the air ratio. As temperature detection device, use can be made of a spatially integrating sensor, such as a resistance thermometer, or a locally active sensor such as a thermocouple. <IMAGE>

Abstract: A method is proposed by means of which the consumption of ink in an offset-printing machine can be determined. The consumption is determined from the settings of the ink gap openings. These ink gap openings form the ink film thickness (sF) which is transferred to the ink ductor roller. Furthermore, the width (bF) of the ink stripe, which is determined by the speed of rotation of the ink ductor roller, and the length (lF) of the ink stripe corresponding to the length of the ink ductor roller are decisive for the consumption of ink. The data are fed to the computer of the control panel of a printing machine. Additionally in the calculation both printing machine related and ink related values, such as, for example, ink temperature, type of paper etc., are to be taken into consideration. The accuracy of the determination of the consumption of ink can be optimised from proportions of surface covering of the plate and ink film thicknesses on the printed sheet, which are determined via the printing plate reader and ink film measuring apparatus. …<IMAGE>…
