Title: Object-monitoring method
Inventor: SCHUBERT PETER
IPC: G08B13/186
Filed: 1989-02-27
Abstract: A method is specified for monitoring objects while using an optical waveguide, whose backscattering characteristics are changed due to mechanical deformation as a result of respectively moving in each case one of a large number of objects arranged at distances along the optical waveguide. The optical waveguide is supplied with short light pulses which are reflected back as light signals containing deviations corresponding to the backscattering changes. The light signals are converted into electrical signals whose corresponding deviations are evaluated as alarm signals.

Inventor: SANYA OLUFEMI DIPL ING
IPC: H03J1/00
Filed: 1989-08-23
Abstract: If previously stored transmitters (channel numbers) allocated to certain programme settings in an entertainment electronics appliance are to be reallocated to the usual programme settings, for example because of changed transmitter distribution (channel number) due to a change of location, reprogramming is necessary. This programming process is very time consuming. The aim of the invention is to obtain a simple sequencing process for reallocating previously stored channels to the desired programme setting number. To this end, a microprocessor (5) receives a command, within a time window predetermined by the command, to read previously programmed data concerning two selected programme settings from a main memory (8) into an auxiliary memory (2/3), from this auxiliary memory (2/3) into another auxiliary memory (4), interchanging the channel numbers, and from this auxiliary memory (4) into the main memory again (8), keeping the same programme numbers.

Patent DE-3930958-A1 (DE)
Inventor: CONRAD ARMIN
IPC: H02K29/12
Filed: 1989-09-16
Abstract: DC motors without collectors require position sensors, which recognize or identify the angular position of the rotor, in order to supply a pulse for control of the current in the coil at a suitable point in time. Hall probes which, as a rule, are used as positional sensors, involve a series of disadvantages, such as for instance sensitivity to temperature and radiation. In order to avoid these disadvantages, coils with a magnetic core through which alternating current is passed are installed in the stator-rotor air gap in accordance with the invention. The rotor comprises in the axial segment opposite the coils a magnetic portion and a nonmagnetic portion. This generates a change in the voltage drop at the coil during each rotor revolution.

IPC: A61K6/884
Filed: 1990-02-15
Abstract: The invention relates to filler-containing, swellable bead polymers, to their preparation, and to their use in polymerisable dental compositions. It is known, for example from US 4,396,377, to employ crosslinked, swellable bead polymers based on methacrylates in dental materials, in particular for the production of artificial teeth and prostheses. Since these bead polymers are not reinforced by inorganic fillers, the materials produced therefrom have inadequate mechanical strength for some areas of application, for example use as filling material in the area of the buccal teeth (cheek teeth, posterior teeth).

Abstract: In a window or door construction comprising, arranged in a casement 1, multi-pane glazing in the form of a stepped double glazing unit 10, a shoulder 14 of a profiled part 13 of the casement engages under the shorter pane 11 of the stepped double glazing unit 10. The shoulder 14 has a receiving groove 18 for the insertion of an inner leg 20 of a holding piece 19, the holding piece engaging by a shorter, outer leg 21 round the outer edge of the double glazing unit. The outer leg runs at an acute angle and the inner leg at an obtuse angle with respect to the web 22 of the holding piece 19 which connects them, so that as the inner leg 20 is pressed increasingly into the receiving groove 18, the clamping force pressing the unit 10 against, on the room side, a bearing leg of the casement profile 13 increases. The web 22 is strengthened increasingly to the inside, so that, when the holding piece is fitted, an increased clamping force is also obtained in the plane of the unit. <IMAGE>

Inventor: KRONSEDER HERMANN
IPC: B65B21/18
Filed: 1990-07-31
Abstract: The inventions concerns a packing device for filling and/or emptying bottle crates (36), etc. The device has an arm (8) on which a gripper head (22) is mounted and which is hinged at two points (13, 14), forming a hinged-rod system which is guided by guide rods (6, 7, 9) to move in the same way as a parallelogram linkage, the arm (8) being moved by means of a cam (18) in a substantially horizontal direction. The invention calls for the guide-rod system to have a two-element guide device whose elements can pivot with respect to each other. The two elements of the guide device can be pivoted with respect to each other by means a second cam (19), and hence the effective length of the device made up of the two guide elements is altered and a substantially vertical motion is superimposed on the horizontal motion of the arm, thus producing a suitable gripper-head trajectory.
