Patent DE-3701674-A1 (DE)
Title: Inlet port for a valve-timed four-stroke internal combustion engine
Inventor: GLANZ REINHARD DIPL ING
IPC: F02B31/06
Filed: 1987-01-22
Abstract: A plate (8) can be inserted into the inlet port (1) of an internal combustion engine, through the slot (7) beginning on that side of the inlet port facing the cylinder axis (5), preferably into the annular space (4) arranged around the valve stem (3), by means of which plate the flow cross-section of the inlet port (1) can be adjusted from the full cross-section to a predeterminable minimum size and a swirl in the cylinder thereby adjusted from a low to a high value. The movement of the plate (8) is preferably controlled as a function of the operating state of the internal combustion engine. A greater or lesser part of the cross-section of the inlet port is covered according to how far the flat plate (8) is inserted into the slot (7), thereby producing an increased swirl in the cylinder. When the plate is withdrawn, the air can also flow past on the other side of the valve stem, thereby bringing about a reduced swirl together with an improved through-flow. The increased swirl is therefore advantageously assigned to a partial load of the internal combustion engine (Fig. 1). <IMAGE>

Title: Method for controlling the regeneration of a particulate filter
Inventor: BAUER RICHARD DIPL ING
IPC: F01N9/00
Filed: 1987-07-16
Abstract: Particulate (soot) filters have the disadvantage that they become blocked during the operation of the internal combustion engine. The intention is to indicate a method for controlling the regeneration of a particulate filter which makes it possible to obtain a measure of the thickness of the coating of the particulate filter in all load universes and at all speeds of the internal combustion engine in order thereby to allow effective regeneration of the particulate filter in a manner matched to the requirements to be controlled. The value of the exhaust backpressure P and of the engine speed N is used to calculate a measure of the thickness of the coating of the particulate filter and this calculated value B-Au is compared with a predetermined maximum value B-max of the thickness of the coating, and regeneration is initiated when the maximum value is exceeded. <IMAGE>

Title: Device for determining mass fluctuations along the sliver length of a fibre sliver, especially in auto leveller drawframes of spinning preparation machines
Inventor: GUENKINGER SIEGFRIED
IPC: D01G23/06
Filed: 1987-08-11
Abstract: A known device contains a compacting funnel which is held on a supporting part and through which the fibre sliver runs. Mounted on the compacting funnel is a sensor, by means of which structure-borne sound can be recorded. The mass fluctuations in the fibre sliver can then be derived from the signal generated by the sensor. To reduce spreads which are located, for example, on the machine side and which act on the sensor via the supporting part and the compacting funnel and therefore falsify the sensor signal, provision is made, according to the invention, for mounting the compacting funnel elastically on the supporting part. The device can be used in auto leveller drawframes of spinning preparation machines.

Patent DE-3823409-A1 (DE)
Title: Drill for making undercut holes
Inventor: BOHNET HARTMUT
IPC: B23B51/00
Filed: 1988-07-09
Abstract: Drills with a widened drilling tip are known which enable the hole to be reamed at the bottom of the hole by a pivoting movement. Undercut holes can thereby be made. Since the drill shank has a distinctly smaller diameter than the drill head, the drill shank is not guided by the wall of the hole. In the transition area between drill head and drill shank, laterally projecting pins are provided which serve as a rectilinear guide and finish-ream the hole. Large hole tolerances can thereby be avoided.

Patent DE-3904530-A1 (DE)
Title: Arrangement and process for magnetic information storage
Inventor: JAEGER KONRAD DIPL PHYS
IPC: G11B27/36
Filed: 1989-02-15
Abstract: For reducing the requirements in terms of precision and speed demanded of the mechanical subsystems of information storage arrangements, in particular those which are compact, mobile and/or to be operated under aggressive conditions, the mechanical movement between magnetic head and magnetic coating is supplemented by the non-mechanical displacement of a magnetic reversal front, generated by controlling magnetic fields within the magnetic head. The recording operation comprises successive changes in the direction of the controlling magnetic fields with decreasing amplitude in each case, the difference between successive amplitudes representing a measure of the information to be recorded. The reproducing operation comprises a preferably constant increase in the absolute intensity of the controlling magnetic fields, taking place between changes in direction, at a rate of increase dependent on the relative speed of the movement between magnetic head and magnetic coating.

Patent DE-3919676-A1 (DE)
Title: Video cassette with a counter for indicating plays
Inventor: BRESSLEIN HELMUT
IPC: G11B27/34
Filed: 1989-06-16
Abstract: In the case of video cassettes it is necessary that a check is kept on the number of plays. For this purpose, known video cassettes are provided with a counter which is advanced by one increment after each playing operation. In addition, known video cassettes have blocking devices which become effective after reaching a certain number of plays. According to the invention, the checking of video cassettes by means of very simple components is made possible by there being arranged in the cassette housing a movable component which can be moved out of a position of rest and causes the counter to be incremented each time the video casette (63) is introduced into the video recorder, and by a block which prevents further playing of the video cassette (63) being able to come into effect when a fixed value is reached in the counter. The magnetic tape cassette according to the invention has simple and easy-to-assemble components which ensure an indication which cannot be falsified of the plays of the magnetic tape and reliably make a block come into effect after a certain number of plays, in such a way that, for example in the case of video cassettes, the last play before the ultimate blocking of the video cassette still reproduces clear video recordings. <IMAGE>
