Title: Method for the use of optical fibre bundles of non-parallel light-guiding fibres
Inventor: EIKELMANN ECKARD DIPL ING
IPC: G02B23/26
Filed: 1993-06-01
Abstract: For image transmission in endoscopes or similar devices, optical fibres which are arranged in parallel have been used until now. The production of this type of optical fibre bundles necessitates a complex procedure. Bundles of this type have a reduced flexibility. They permit, if need be with high outlay, an integration of additional optical fibres. To remedy these disadvantages, a method is provided of using optical fibre bundles, made up of non-parallel light-guiding fibres, for visual and measurement purposes, the light being coupled (launched) at a coupling-in side into the optical fibre bundles and being coupled out (extracted) therefrom at a coupling-out side. In this process, the individual light-guiding fibres are marked at the coupling-out side and their coordinates are determined. The light-guiding fibres established at the coupling-out side are then determined at the coupling-in end and their coordinates are likewise determined. Finally, the positions of the individual light-guiding fibres at the coupling-out end are converted into the coordinates of the corresponding light-guiding fibres at the coupling-in end.

Title: Gear shift control system for vehicular automatic transmission - enables hydraulic valve to be operated directly from gear selector lever, or indirectly via interposed drive unit
Inventor: MOROTO SHUZO
IPC: F16H63/08
Filed: 1993-07-20
Abstract: A drive unit (3) and a connection/sepn. device are introduced in a working connection between the gear selector lever (21) and an actuating slide-valve (50). This connection consists of a control arm (22) and rod (23), a lever (24) rotating the actuating shaft (15), a latching lever (26) and another rod (27). For changes between positions with the vehicle at rest, the drive unit is deactivated so that the selector lever acts directly on the valve. ADVANTAGE - Simple and smooth gear changes can be made manually with the drive unit isolated, without requiring any increase in bulk of the appts.
Patent DE-4325751-A1 (DE)
Title: Method, lock and welding device for the liquid-tight connection of diaphragm sections of a trench wall
IPC: E02D31/04
Filed: 1993-07-31
Abstract: The invention relates to a method, a lock and a welding device for the liquid-tight connection of the lock halves, lowered into a suspension, of successive diaphragm sections of a trench wall. Put in a flat-spread manner into the one lock half, consisting of an outer profile element, of the one diaphragm section is the other lock half, consisting of an inner profile element, of a following diaphragm section. An inner groove extending essentially over the length of the lock is made in the wall of the inner profile element. The groove cuts through the wall of the inner profile element and extends right into the wall of the outer profile element in order to weld the inner and outer profile elements to one another in a liquid-tight manner by applying welding material to the groove walls. In order to keep the groove walls free of seepage liquid and other impurities until the welding operation is complete, provision is made to seal off the profile-element wall area accommodating the groove from the trench-wall suspension by a sealing agent before the profile elements are welded.
Patent DE-4327090-A1 (DE)
Title: On jet or rocket propulsion unit in which the gas is used repeatedly after the inner thrust nozzle
Inventor: SCHAEFER ALEXANDER
IPC: F02K3/10
Filed: 1993-08-12
Abstract: It is known that the momentum of the reactive flow is equivalent to l = mV, and the force of the flow can accordingly be denoted as a derivative of the momentum divided by the time differential:  F = dl/dt = (m(V + dV)-mV)/dt = ma It follows from the statement that the reactive force is a function of the acceleration of the reactive flow which, where the thrust nozzle is used, is negative. In this case the action of the reactive force will be counter to the direction of flow. Due to the fact that the reactive force is a function of the acceleration and the mass of the flow in the jet or rocket propulsion unit, the thrust nozzle can also be used inside the jet or rocket propulsion unit. As a consequence of the use of the thrust nozzle inside the propulsion unit, the reactive flow or gas can be re-diverted into the combustion chamber for generating a greater mass of the reactive flow flowing through the thrust nozzle. An embodiment of the invention is shown in the drawing and is described in more detail below. <IMAGE>

Title: Start up method for ring spinning machines - relates start of yarn delivery and traverse movement to balloon size to reduce end breaks
Inventor: WOLF HORST
IPC: D01H1/34
Filed: 1993-08-24
Abstract: A ring spinning machine has a drive and control mechanism for the various components so that during start up the delivery of yarn (11) from the drafting system (6) is related to the growth of the yarn balloon. Pref. a ring spinning machine has spindle driven by individual motors (10) and drives (14) for the ring rail (4). Sensor lines (19,20,21) provide performance feed back to a controller (22) with a data store (18). The start up procedure is tailored to the conditions in which the machine as shut down and programmed or emergency shut downs are treated similarly. The ring rail is first moved a small distance from its last position to straighten out any yarn loops. The spindles are then started to build up the yarn balloon with no yarn delivery and a stationary ring rail, so that twist is inserted to strengthen the yarn. Yarn delivery and traverse motion is started once the balloon is fully established. USE/ADVANTAGE - For reducing end breaks during starting of ring spinning machines, esp. after an unscheduled stop. Removes yarn loops from threadline and inserts extra twist before starting traverse motion.

Patent DE-4418731-A1 (DE)
Title: Control and regulation of processes in motor vehicles
Inventor: ADLER WALTER DIPL ING
IPC: B60T8/175
Filed: 1994-05-28
Abstract: A method for controlling/regulating processes in motor vehicles is useful for example for controlling/regulating combustion processes, gear shifting processes or braking processes. The process uses a characteristic field. The characteristic field is defined by working parameters of the relevant process and is represented by a number of nodes (30). The corresponding controller contains information on the value of the characteristic field at the position of each node (30). When the process is controlled/regulated, at least one characteristic field value decisive for a given point of operation (31) is determined from the characteristic field and taken into account when establishing a controlling variable for supplying a control signal. The characteristic field is automatically adapted to changes in the process. For that purpose, a correction value for a specific phase of operation of the characteristic field is determined. The process further provides information on the position of each node within the characteristic field, so that the nodes (30) may be input into the characteristic field independently of a fixed grid. A plurality of nodes (30) of the characteristic field located around the determined correction value are selected for adaptation of the characteristic field. Said nodes are then adapted, the nodes being corrected as a function of their distance from the position of the determined correction value within the characteristic field.
