Title: Device for changing the size and direction of propagation of vortex rings
Inventor: LIPPOLD ANDREAS DIPL PHYS
IPC: A63J5/02
Filed: 1987-05-27
Abstract: The invention relates to devices with the aid of which the size and direction of propagation of vortex rings can be changed. The change in the direction of propagation is produced by pivoting the outlet diaphragm. The latter is coupled to the vortex ring generator in a gas-tight and movable fashion. The change in the size of vortex rings is produced by changing the diameter of the outlet opening. Both the variation in diameter and the change in the direction of propagation are driven electrically or pneumatically and can be controlled via signal generators.

Title: Circuit arrangement for pulse counting circuits
Inventor: HOFFMANN JUERGEN DIPL ING
IPC: H03K21/18
Filed: 1987-05-29
Abstract: Circuit arrangement for pulse counting circuits which are equipped with one or more 4-decade up/down counters and one BCD 7-segment decoder and uses, for driving a LED display, the multiplex outputs present for this purpose on the counters by connecting control transistors downstream and BCD outputs. The invention attempts to solve the problem of achieving a suppression of the first or most-significant LED position if the corresponding zero information is present at the BCD inputs at the BCD 7-segment decoder. This is achieved by the collector of the control transistor connected to the most-significant LED position also being signal-connected via a resistor to the base of a further transistor which is connected to the RBI input of the BCD 7-segment decoder by its collector.

Patent DE-3818252-A1 (DE)
Inventor: GIESEN KARL
IPC: D04H13/00
Filed: 1988-05-28
Abstract: A padded member consists of a filling which contains a nonwoven, around which a covering material is placed on one or both sides. In order to produce an inexpensive, form-stable product having good support properties, it is proposed that the filling be formed from a so-called voluminous nonwoven, in which there are binding fibres made of material which is capable of thermofusion. This binding-fibre nonwoven is compression moulded with the covering material to form an integral padded shaped member and a relief is thereby generated at least in some regions on its face side. In accordance with the relief profile, the binding fibres are deformed in the interior of the nonwoven and are thermofused both with one another and with the covering material, by which means the relief is permanently fixed in the padded shaped member. For this purpose, a special method for producing a padded shaped member of this type is also proposed. <IMAGE>

Title: Contactless potentiometric angular position or displacement transducer
Inventor: FRENK HELMUTH DR
IPC: G01D5/165
Filed: 1988-06-28
Abstract: The invention relates to potentiometric angular position or displacement transducers operating with alternating current, in which to date only the amplitudes of a plurality of pickups of the same phase of a transmitter (sensor) have been used as measured values. According to the invention, the previous pickups are excited as transmitters by means of phase-shifted voltages in such a way that they generate rotating (rotary) fields or continuous fields and the phase angle of the tapped measurement voltage is the measurement information. Simple circuits for generating precise transmitter voltages are specified for inductive transmitters. Capacitive transmitters are particularly simple and economic and are stimulated using delta voltages. They can be filled with a dielectric liquid which upon being replaced by an electrically conductive liquid produces a contactless resistive potentiometric transmitter.
