Title: Circuit arrangement for controlled voltage supply of remotely powered terminal devices in telecommunications systems, in particular telephone systems
Inventor: DRAGOTIN ALEXANDER DIPL ING
IPC: H04M19/00
Filed: 1982-02-09
Abstract: The voltage for the terminal devices (E), which in particular represent digital telephone terminals, with different power requirements determined by different operating conditions, is fed in via a switching controller (SR) disposed in the exchange. The latter is controlled in such a way that the feed voltage supplied by it is equal to the sum of the voltage on the peripheral device and the voltage loss on the line resistor (R1). A voltage stabiliser (LR) with a serial controller element (T2) is provided in the respective terminal device. This controller element is used exclusively to enable the depicted control process. As a result of its response to fluctuations in the voltage on the peripheral device around the desired value, the voltage stabiliser (LR) provides the switching controller in the exchange with the information required to increase or decrease the feed voltage supplied by it. The switching controller is pulse-width controlled. The control information is coupled into a potential-isolated control circuit from a voltage-frequency converter (SF), which in turn is controlled by the voltage drop on a measuring resistor (R1) connected to the feed-in point in the line. <IMAGE>

Title: Logic game
IPC: A63F9/08
Filed: 1982-04-16
Abstract: This application, as a patent of addition, relates to logic games in a planar arrangement. Like other logic games, this challenges the player to determine the moves, and the sequence thereof, which result in a particular final configuration, arranged by colours. These games consist in principle of intersecting rows arranged flatly in a body, which rows can be moved individually in any desired sequence. By using balls and cylinders, or cylinders with tiles, each of which possesses two semi-cylindrical recesses positioned perpendicularly to each other, rows are formed whose cylinders can either always be moved in the lengthwise direction only and are blocked in the transverse direction, or alternatively can be moved in both the lengthwise and the transverse directions. As a result, obstacles are formed, and the game takes on a unique degree of difficulty. <IMAGE>

Title: Central suctioning of apparatuses for cigarette strand formation
Inventor: DRABNER MANFRED DIPL ING
IPC: A24C5/18
Filed: 1982-10-04
Abstract: The central suctioning of apparatuses for cigarette strand formation is used on machines where a negative pressure is generated by means of an air stream at strand-forming mechanisms, for example for the production of cigarettes. By physically separating the entire ventilation and dust-removal equipment of machine and working area, the nuisance caused by dust and noise in the working areas is to be reduced and the amount of wear on units of the installation lessened. For this purpose, a central fan, immediately preceded by a central dust separator, is installed outside the working area. The central fan generates an air stream which, by means of a central network of pipes, produces a negative pressure at the strand-forming mechanisms of cigarette strand machines, there being arranged between the connections of the network of pipes to the individual cigarette strand machines control elements which avoid any mutual influencing of the negative-pressure conditions between a number of cigarette strand machines at different load stages.
