Title: Automatic repeat dialling circuit - has subscriber command digit to store or not store dialled number
Inventor: BARTHOLOMAE HENRIK ING GRAD
IPC: H04M1/272
Filed: 1980-03-26
Abstract: In a central exchange control station (ZST) is provided a number storage unit (SP) in which one storage word sufficient for an n-digita dialling number is reserved for each subscriber- individual equipment set. To enable the subscriber to decide whether a particular call if not immediately successful should be stored for automatic repeat dialling the dial number receptor set (WAS) contains an additional digit position which can store a command signal from the subscriber, and which, on transfer to the central exchange, also loads the subscriber-owned storage line in the store (S). An alternative enters all the dialled numbers into the sbuscriber-owned storage position for repeat dialling and the subscriber has the option to cancel the storage. Or, by a prefix to the dial number the subscriber inhibits the writing of the call number from the number repeater (WAS) to the dial repeat storage unit (SP). In doing so, the last-but-one call would be abandoned as far as the aut. re-dialling function is concerned.

Patent DE-3110074-A1 (DE)
Title: Device for testing modules containing electronic circuits
Inventor: HARTMANN BERND
IPC: G01R31/28
Filed: 1981-03-16
Abstract: Test instruments for electronic components generally exhibit contacts to which the specimens under test are clamped or onto which they are plugged. To establish that proper contact has been made, it is proposed to connect a test voltage generator (PSG) individually via a current discriminator (DIS) to the contacts (K1, K2 ... Kn) with the specimen under test (PR) plugged on, and to monitor the test current flowing during this process. If this current drops below a predetermined value, the current discriminator (DIS) outputs an indicating signal. The main field of application of the invention is test instruments, particularly logic analysers. <IMAGE>

Title: Steam power plant with complete waste heat recirculation
Inventor: GENSWEIN GEB SCHMITT
IPC: F01K19/04
Filed: 1981-06-06
Abstract: A so-called "gas-steam cycle" is proposed which can be operated between the superheated and saturated states of a superheated or cold steam and thus avoids the heating and vaporisation of the feed liquid via the boiler or vaporiser. The compression and hence recirculation of the working medium including the waste heat can thus be carried out virtually without problems by means of a turbocompressor, spiral compressor or piston compressor (Figs. 1 and 2). Complete utilization of the primary heat fed to the cycle is possible here because, upon expansion, the working process makes a transition from the gas phase to the vapour phase (1->2, Fig. 4) and, during the subsequent compression (2->3, Fig. 3), the wet steam can be compressed isothermally and then adiabatically (isentropically) and the heat of compression in the range of the isotherm ( chi  = 1) can be absorbed by the working medium itself in the form of heat of vaporisation, i.e. does not have to be carried away to the environment. It is hence possible to state the following "new finding": heat can be converted completely into mechanical work. It is irrelevant here whether the temperature of the heat energy to be converted is above, at or below the ambient temperature level. This gives an intrinsically continuous (perpetual) circulation of the energy in the two states:       Heat -> mechanical work -> heat With multiple resuperheating, a high heat transformation in the superheating region and hence a high performance per expansion stroke are achieved even at relatively low operating temperatures (practical application in particular in cold-steam power plants). <IMAGE>

Patent DE-3133922-A1 (DE)
Title: Wheelbarrow
Inventor: KLEBER JOHANN
IPC: B62D51/00
Filed: 1981-08-27
Abstract: The invention relates to a wheelbarrow. For the transport of loads, wheelbarrows require a considerable amount of physical force. With large loads, long distances and difficult terrain, the person wheeling the barrow becomes tired easily and, as a result, the efficiency of transportation decreases. According to the proposal of the invention, high efficiency of transportation can be achieved, even under difficult conditions, namely by a drive which can be switched on and acts on a running wheel, the drive essentially comprising a motor, optionally with a gear mechanism, a power source and a device for power transmission. A wheelbarrow according to the invention can also be manoeuvred freely, as previously, and is thus capable of being used anywhere. Expediently, the motor and at least part of the device for power transmission are mounted on a pivotable frame underneath the loading area. The device for power transmission advantageously has a frictional wheel. <IMAGE>

Patent DE-3138557-A1 (DE)
Inventor: HEINLE GEORG DIPL ING
IPC: G01R31/34
Filed: 1981-09-28
Abstract: The machine flux of a rotating-field machine is determined from the digitized values of the machine stator terminal voltages and conductor currents averaged within a sampling period of an associated digital evaluation system. In order to form each component of the machine flux, the average value of a stator terminal voltage of the same phase, reduced by the ohmic voltage drop in that phase of the stator winding of the rotating-field machine, is multiplied by the clock period of the digital evaluation system and by a scaling factor and the average values so formed for each clock cycle are summed up. From the integral so obtained, the digitized value of the conductor current of the same phase averaged within a sampling period of an associated digital evaluation system and appropriately scaled, is substracted. The simulation of the machine flux can thereby be accomplished digitally. Because averaged values of the terminal voltages and conductor currents are used in the method, there are no sampling problems in digitizing the values.

Title: Method and apparatus for cold forging
Inventor: RAMNESTEN IVAN
IPC: B21J13/10
Filed: 1981-10-05
Abstract: Grooves are produced on the inside of metal tubes by hammering the workpiece in a cold forging machine, such as a rotary die forging machine, over or around a mandrel provided with a screw thread. In the production of internal profiles of great depth, for example in the production of ball bearing nuts made of sintered carbide, grooves and gearwheels with internal toothing, considerable shear stresses occur between the mandrel and the workpiece. The invention provides a method and an apparatus for avoiding unwanted shear stresses on the mandrel and the workpiece by means of a rotatable mounting for the connecting rod, which can in addition be braked, in order in this way to obtain a controllable slip at the friction surface (11) between the workpiece (8) and the connecting rod (10). <IMAGE>
