Title: Electronic ignition system without ignition distributor for motor vehicles
Inventor: MUELLER HERMANN
IPC: F02P5/155
Filed: 1989-01-10
Abstract: The electronic ignition system without ignition distributor replaces the conventional mechanical high-voltage ignition distributor in motor vehicles with internal combustion engines without automatic ignition. In order to realise this, an electronic system is developed which permits the ignition process and ignition sequence to be configured in an optimum way in each speed range and power range without the customary mechanical transmission elements. The evaluation of pulses by means of inductive sensors on the crank shaft and cam shaft is characteristic of the electronic system. The electronic system controls the emission of signals in the correct sequence to the 4 ignition coils and switches them on and off appropriately. The displacement of the ignition time with increasing engine speed including the respective load (partial load operation/full load operation) is corrected or adapted by means of the intake partial vacuum. The drawing "electronic ignition distribution" shows the principal mode of operation and design of the electronic system. The main advantages of the electronic ignition system are:     - adjustment of the dwell angle is omitted, - single adjustment of the ignition time and maximum ignition displacement,   - greater availability and reliability,   - higher control precision,   - better combustion, economy and power generation of the engine,   - no maintenance,   - saving in costs. The electronic ignition system is primarily intended for use in motor vehicles without self-igniting combustion but fundamentally ... the use in ... previously with mechanical ignition ...

Title: Measurement device
Inventor: BLAUTH WALTER PROF DR
IPC: A61B5/11
Filed: 1989-03-06
Abstract: The invention relates to a measurement device for determining the active and passive mobility of the shoulder joint. The measurement device comprises an electromechanical and a computer-controlled unit. The electromechanical unit is firmly connected to the seat of the patient and to his/her arm in such a manner that the arm can point at any angle in space that is possible for the shoulder joint. The electromechanical unit has two axes of rotation which are coupled to one another via a bracket and whose axial extensions meet in the centre of the head of the humerus imagined as a ball. The computer-controlled unit represents the extreme angular positions in space which can be attained by the stretched arm serving as indicator as a closed curve in a surface projection.
Patent DE-3908646-A1 (DE)
Title: Drill stem
Inventor: KLEMM GUENTER DR
IPC: E21B17/07
Filed: 1989-03-16
Abstract: The drill stem has a first drill rod (10) and a second drill rod (11) arranged coaxially in the first drill rod (10). The second drill rod (11) is telescopically displaceable in the first drill rod (10). When the second drill rod (11) is retracted, a borehole is drilled up to the length of this second drill rod. The first drill rod (10) is then retracted while rotating against the direction of rotation during the first drilling step, as a result of which the drill stem is lengthened by the second drill rod (11) being extended from the first drill rod (10). In a second drilling step, the hole drilled during the first drilling step is lengthened. The telescopic drill stem enables a borehole to be drilled whose depth is greater than the feed distance of the drilling implement used without drill rods having to be coupled to one another. <IMAGE>

Title: Tear-off lid for a container
Inventor: WIPPERFUERTH WILFRIED
IPC: B65D17/347
Filed: 1989-03-24
Abstract: An attachment section (7) of a tear-off tab (5) is fixed on a plane (2) of a tear-off lid (1) by a rivet (10) moulded out of the lid plane (2). A pivoting safeguard prevents the tear-off tab (5) being pivoted relative to the rivet (10). This is brought about by the fact that a rivet opening (8) of the attachment section (7) and an opposite section of the shank (9) of the rivet (10) are designed to be non-round. <IMAGE>

The suction heads are mounted on a ring which is driven so that as it rotates its axis of rotation rotates about a fixed horizontal axis. This double motion results in the tangential velocity of each suction head being zero at the instant at which the suction head comes into contact with the sheet of packing material so that the sheet is lifted vertically from the stack of sheets. USE - Packing machines.

Title: Cardio-version and defibrillation procedure - applying at least three electrodes on breast and back of patient for ventricle or auricle palpitation
Inventor: HALLSCHEIDT PETER
IPC: A61N1/39
Filed: 1990-10-22
Abstract: Electrical current pulses are introduced into the patient by applied electrodes. Near the heart, at least three electrodes are distributed over the front and back of the patient. An electrical potential is applied to at least two of these electrodes so that at least one electrical field is generated and maintained for a short period. All the electrodes are connected to a central control. The latter can switch on various electrode pairs or groups. A vector loop corresp. to the natural physiological sequence can thus be formed by change over of switching. The heart areas stimulated by the electric field can thus be sequentially depolarised. ADVANTAGE - Reduced electrical loading of patient and hence lower risk.
