Patent EP-0128539-A2 (EP)
Inventor: SCHYMA MICHAEL DR-ING
IPC: F02B75/04
Filed: 1984-06-07
Abstract: The process is for a four-stroke combustion engine having a piston connected in the usual way to the crankshaft and also a movable auxiliary piston. The operation of the said engine comprises the known four strokes of expansion, exhaust, induction and compression. In the case of known engines of this type which are operated with auxiliary pistons, the compression chamber is enclosed by piston and auxiliary piston and, if appropriate, taken along downwards with its size remaining constant beyond the upper dead centre position of the piston, the ignition already being able to take place at the upper dead centre position. This produces a more favourable angle of rotation at the crankshaft and consequently a better torque. However, such engines produce highly polluting exhaust gases and operate with poor efficiency, so that in spite of the proposed measures they do not perform well in terms of torque and power as well as consumption and emissions. If the known four-stroke process described is taken as a basis, this can be improved by making the compression chamber of the auxiliary piston at least approximately zero at the end of the exhaust phase, and at the latest at the upper dead centre of the main piston, and maximising it during the subsequent induction phase until, at the latest, the lower dead centre of the main piston. During the following compression phase, at the upper dead centre of the main piston the said piston encloses with the auxiliary piston a compression chamber which, during the following downward stroke to a desired angle of rotation of the crankshaft, is quickly reduced to a desired size before ignition takes place. <IMAGE>

Abstract: Aufgabe der Erfindung ist es, einen mit gewichteten Konstantstromquellentransistoren arbeitendnen D/A-Wandler zu schaffen, der einerseits eine kompakte Integrierung auch bei einer größeren Anzahl von Wandlerstufen erlaubt und dabei temperaturunempfindlich arbeitet. Erreicht wird dieses Ziel, indem die vorgesehenen Wandlerstufen in zwei Gruppen unterteilt sind, wobei die zu der ersten Gruppe gehörenden Stromquellentransistoren sowohl bezüglich ihrer Emittervorwiderstände als auch bezüglich ihrer Emitterflächen dual gewichtet sind, während bei der den niedrigen Bitwertigkeiten angehörenden zweiten Gruppe von Wandlerstufen sich die duale Wichtung auf die Emittervorwiderstände beschränkt, während die Emitterflächen der Stromquellentransistoren dieser Gruppe alle gleich bemessen sind und dem Stromquellentransistor der niedrigsten Bitwertigkeit in der ersten Gruppe von Wandlerstufen entsprechen. Um dennoch die Temperaturunempfindlichkeit zu erreichen, werden von dem Referenzstromkreisausgang die Basen der Stromquellentransistoren in unterschiedlicher Weise gesteuert, wozu jeder Gruppe Vermittlungstransistoren und je eine Konstantstromquelle zugeordnet sind.

Abstract: 57 A multi-microprocessor implemented data processing system (10) having a single cycle data transfer capability for its memory mapped peripheral devices (16) is described. A host of controlling microprocessor (12, 14) provides address and control signals for memory (24) accesses. In addition, it also determines that a peripheral (16) operation is desired. When this occurs, a command is sent to the selected peripheral and a memory cycle, fetch or store, for the data transfer is initiated. The address bus is provided with the memory address for the needed data and a special decode that indicates the unique nature of this memory access. Logic circuit means (28) are provided to detect the special decode and to intercept the data bus (22) at the appropriate point in the bus cycle in response thereto. The logic circuit means is adapted to then responsively apply the correct control signals to the peripheral (16) to enable the desired data transfer after the data bus has been intercepted.

Abstract: The apparatus or the measuring head (26) comprises a housing (30), in which a light source (32) and a light-sensitive element (34) are arranged. From the light source (32) light energy is directed via optical fibres over a profile (24) to be monitored. Light energy is picked up by optical fibres (44), which direct the light to the light-sensitive element (34). Due to the arrangement of optical fibres, the measuring head can be made very thin, so that it can be arranged directly in the hold-up area ahead of a calibrating device. In order to eliminate disturbing light effects from the surrounding area, a filter (46) is arranged in front of the light-sensitive element (34). The fine setting of the measuring head (26) is performed by means of a stepping motor and the controlling of the hauling-off device of the extruder is performed with a delay after detecting the tendency of a proportional change in the profile ahead of the calibrating device. <IMAGE>

Abstract: The device is intended for the selection of certain sound-image recordings even when the recorder has been in use for any length of time, by picking up signals proportional to the tape travel and evaluating them by a pulse processor. A sequence of numbers transmitted by remote control sets the pulse processor to the number corresponding to the desired point on the tape, which determines the position at that instant and switches by fast forwarding or fast return just before the desired point to fast search mode with the magnetic heads applied, only switching over to normal playback when a black code is received via the recorder's own video socket at the beginning of the desired point on the tape. It then passes the video signal on to the monitor and at the same time sets the processor to the exact code number corresponding to the respective point on the tape, as a result of which any counting error arising due to different tape winding is corrected to zero.

Abstract: To control with precision and repeatability the amount of fluid dispensed or aspirated by a pumping system, a volume disk rotates with the output shaft of a DC motor that drives a reciprocating dispensing pump. A sensor detects indicia on the disk and provides periodic signals spaced-apart in time: (1) an amount proportional to the volume of fluid pumped; - (2) proportional to the angle between indicia; (3) an amount less than one-third of the length of the total stroke of the piston as the piston moves linearly in its working portion of a cycle; and an amount necessary for the piston to sweep out a volume of less than five milliliters. The speed of the pump is controlled by a second disk having equally spaced indicia that are sensed to provide signals proportional to the motor speed. During dispensing or aspirating large volumes, the motor speed is increased to a high speed, run at the high speed and then decreased before stopping and during dispensing smaller volumes, it is maintained at a constant lower speed.

Abstract: The invention relates to a method and to a circuit arrangement for converting a HDB3 data signal into an MCMI data signal and is characterised by the fact that the HDB3 data signal is separated into two binary bit streams which, on the one hand, only contain the positive pulses and, on the other hand, only contain the negative pulses in inverted form. The bit streams are sampled with the aid of clocked memories and the second bit stream is delayed by half a clock period and inverted. The latter bit stream and the former sampled bit stream are multiplexed half clock period by half clock period and thus produce the desired MCMI data output signal (Figure 2). <IMAGE>
