Title: Limiting errors in sending selected number over telephone network - by delaying transmission in intermediate store until calling subscriber has finished dialling
Inventor: QUINTENZ REINALD ING GRAD
IPC: H04Q3/42
Filed: 1980-01-17
Abstract: The application is to automatic telephone systems which do not employ a code for indicating the end of a selected number transmission. It reduces the possibility of incorrect connection. The number dialled by a subscriber is held in an intermediate store, and the final digit not released for onward transmission until the subscriber has ceased dialling. The cessation of the number selection process is established by a period, e.g. six seconds, during which no dialling pulses are received from the calling subscriber. Typically, the exchange contains a control unit (ST) which detects a lifted handset (T) through the subscriber line end equipment (TS). The subscriber is connected through the switchboard (KN) to a number receiver circuit (WAS) which retransmits into the line (Ue,V) and sets up the connection. The time delay is typically determined by the control unit (ST).

Title: Noise generator preventing eavesdropping on telephone conversations - assigns one generator to each conductor core to increase operating availability
Inventor: GRUENER PETER ING GRAD
IPC: H04K1/02
Filed: 1980-11-26
Abstract: A background noise generator is connected to telephone lines to make it difficult or impossible to overhear conversations. Where a single central generator is used its failure leaves all lines unprotected. It is proposed to use one generator (RG1a,RG1b...RGna,RGnb) for each telephone line (1a,1b; ...na,nb). The generators are connected with one pole to a core and the other to earth. On the failure of one generator the other on the core pair still provides some measure of security. The generators are typically Zener diodes operated at their break over point, and capacitatively coupled to the core to eliminate any d.c. bias. Limiting resistors prevent excessive diode current.
Patent DE-3105369-A1 (DE)
Title: Circuit arrangement for a voltage regulator with monolithically integrated voltage regulators for correcting an unregulated direct-voltage source
Inventor: GLAS JOSE
IPC: G05F1/573
Filed: 1981-02-13
Abstract: The invention relates to a circuit arrangement for a voltage regulator, a higher voltage being regulated down to a lower voltage by means of monolithically integrated components, in which arrangement the circuit arrangement should not be damaged even with a short- circuited load. This is achieved by the fact that when the load resistance is too low, a diode, due to the change in the potential ratios across this diode, becomes conductive and an additional voltage regulator acting as variable load resistance is added. The result is that the circuit arrangement is not destroyed even in the event of a short-circuited load. The use of the circuit arrangement is of interest to telephone exchangers where a lower voltage is to be obtained from the direct voltage of 60 volts present in most cases.

Title: Device for displaying and storing merchandise of different types on merchandise shelves
IPC: A47B96/02
Filed: 1981-05-14
Abstract: The known merchandise shelves, on which merchandise is displayed for sale in shops, have only a few possibilities of variation. However, a versatile, different range of merchandise is to be displayed. For this purpose, refined possibilities of use must be provided. The subject-matter of the invention is a display device in which the merchandise shelves are suspended by suspension means at their ends in perforated stands or in a rear wall of shelf units, a support rail being arranged at a slight distance from the shelf stands, which support rail can be suspended with suspension hooks in holes in the shelf stands, and the suspension hooks of the merchandise shelves being designed in such a way that they can be suspended directly in slots in the transverse rail and in holes in the shelf stands, and brackets with rows of slots or holes placed against one another being arranged at the ends of the merchandise shelves, into which rows of slots or holes the suspension hooks can be hooked so that the merchandise shelves can be inserted obliquely into the slots in the support rails. Merchandise stands or merchandise shelves of the most varied constructional design can thus be hung up adjacently. In particular, the intention is for merchandise shelves with different suspensions to be able to be hung up adjacently, irrespective of the axial dimension of the shelf stands. In this case, it is possible with an axial dimension of 62.5 cm to suspend the merchandise shelves with ordinary known suspension hooks and, at the same time, the same shelves can be used with a double axial dimension of 125 cm with the hanging or suspension construction. <IMAGE>

Patent DE-3122026-A1 (DE)
Title: Apparatus for separating off liquids and solids from gases
Inventor: CHRISTIAN PAUL
IPC: B01D47/06
Filed: 1981-06-03
Abstract: The abovementioned apparatus has a construction in which the scrubbing liquid carries out the air wetting and gas wetting without interference in the water circulation without spray jets by a spray pump (25) which is situated in a separation chamber (21). The gas flow and/or air flow is produced by the apparatus itself by means of a rotor (19). The act of separation is problematic, if the gas and/or air must be separated from the entrained suspended matter which is composed of solids or liquids. A centrifuge (14), which surrounds the rotor and is mounted without direct drive on the drive shaft (13), is brought into rotation by the radial flow of the rotor (19), a pull being exerted by it on all suspended matter situated in the gas and/or air and the suspended matter being taken up into it. The suspended matter is discharged in the direction of the expanded centrifuge shell (15). The purified gas and/or air leaves the centrifuge through the outlet orifices (16). This apparatus can be used for flue gas purification (SO2) and dedusting, as well as in recycling processes, the type of the scrubbing liquid playing no role. If gas and/or air are to be separated from entrained liquid, the apparatus can alternatively also be used without a spray pump (25). <IMAGE>
