Title: Circuit arrangement for telecommunications switching systems, in particular telephone switching systems, with devices for functional capability testing of switched connections
IPC: H04M3/24
Filed: 1985-04-12
Abstract: In PCM telecommunications switching systems, a double connection is in each case set up to monitor connections or sections thereof, the routes of both arms of which are selected independently of one another in the route search via the switching network(s) and, if necessary, via PCM routes. The data stream passes from the branching point concerned via both arms, and the two data streams arriving at the other end of the double connection concerned are compared here with one another. A comparison in each case monitors isochronous sections from the branched data stream and begins with PCM words which are identical in terms of their time-slot pattern in relation to the consecutive pulse frames. In the event of non-correspondence, further comparison procedures follow in which the relevant sections from the branched data stream have a time-slot pattern difference of one or two pulse frames, a pulse frame difference being defined in both one temporal direction and in the other temporal direction. <IMAGE>
Patent DE-3513379-A1 (DE)
Title: Quick-acting manipulating valve with drive element and controllable stop device
Inventor: MESINA MARIAN DR ING
IPC: F15B13/02
Filed: 1985-04-15
Abstract: The invention relates to a novel quick-acting manipulating valve which is equipped with an oscillator drive and a controllable stop device. A special feature of the valve conception presented is that the task of designing a quick-operating valve is reduced to the tasks of designing a rapidly oscillating drive element and a rapidly reacting, controllable stop device. On the basis of the conception presented, it is possible to reduce the operating times of the valves or to also improve the flow rates. In the process, virtually identical on and off operating times can be achieved. The control signals, irrespective of type, act only on the controllable stop device. This action counteracts the blocking of the movement of the drive element and the operating cycle is thereby initiated. Since the controllable stop device needs distinctly less energy and power for its actuation than is necessary for carrying out the operating cycle in the valve, the dependency between the operating pressure and the control pressure can thereby be reduced in pneumatically controlled valves. In the same way, the demands imposed on the electromechanical valve components in electrically controlled valves can also be clearly reduced.

Patent DE-3519291-A1 (DE)
Title: Process for homogenising and cooling the plastics melt, in particular a plastics melt treated with a blowing agent, and extruder for carrying out the process
Inventor: LANGECKER GUENTER DR ING
IPC: B29C48/605
Filed: 1985-05-30
Abstract: A process for homogenising and cooling a plastics melt in an extruder is specified which is suitable in particular for influencing a plastics melt treated with a blowing agent and takes place during the helical transport of said plastics melt through the screw barrel effected by the extruder screw. A constantly predetermined volume flow of plastics melt is transported in an even number of melt strands. During the transport movement the cross-sections of in each case two directly adjacent melt strands are varied in an inverse ratio to one another and these cross-sectional changes are effected in repeatedly successive alternation. A corresponding partial amount of melt taken in each case from the melt strand subjected to the cross-sectional reduction is fed to the melt strand undergoing the cross-sectional enlargement and the melt in the melt strands is rearranged by the helical transport movement during its cross-sectional change. The invention also relates to the design of the extruder for carrying out this process.

Title: Emergency ignition key for motor vehicles
Inventor: WILHELM FRANZ DIPL ING
IPC: E05B19/00
Filed: 1985-10-24
Abstract: The emergency ignition key for motor vehicles is a special ignition key which is stored secured constantly in the motor vehicle against unauthorised use in a key holder. It fulfils its function only in motor vehicles which are equipped with the device for unlocking locked motor vehicle doors (File No. P 3415355.1). If, despite the absence of an original ignition key, an engine is to be started, the code number is initially to be input with the number wheels and subsequently the switching fork is to be swivelled out to its limit stop. The car door is then unlocked and can now be opened with the door handle. At the same time, the key catch is released so that the emergency ignition key can be removed from its holder. The authorised person is then in a position to switch on the ignition at any time and thus to start the engine of his car, irrespective of the availability of an original ignition key.

Title: Flow rate monitoring device for liquid or gaseous substances
Inventor: STUDZINSKI GEORG
IPC: G01F1/24
Filed: 1986-03-13
Abstract: The flow rate monitoring device for liquid or gaseous substances has a flow duct which is arranged in a housing or basic body of the device and is connected to the line of the substance to be monitored. Provided in the region of the flow duct are electrical devices which detect and display the flow and/or the state of rest in the flow duct and thus in the line. The flow duct or central bore (2) communicates with a duct (bore 5) provided in the basic body (1). The duct (bore 5) accommodates an automatic valve. The sealing member (ball 6) of this valve closes or opens the flow duct (central bore 2) depending on the state of motion of the column, located in the flow duct, of the substance to be monitored. The sealing member is arranged in the region of the opening (10) of the bore (5) into the central bore (2). Furthermore, there is provided in the region of the opening (10) an electrical measuring sensor (proximity switch 7) which controls a signalling device as a function of the position of the sealing member (ball 6). <IMAGE>
Patent DE-3609200-A1 (DE)
Title: Tiled stove
Inventor: STACHEL FRANK-PETER
IPC: F24B9/04
Filed: 1986-03-19
Abstract: The patent application concerns the improvement of tiled stoves for simultaneous air and water heating, whereby a heating box intended for further heating is provided. According to the invention, provision is made for the unit for water heating to be assigned directly to the heating box. The essential advantage results from the fact that the heating box of conventional design can be exchanged very simply for a heating box with which water heating is possible. In other words, contrary to what is known, not the actual, expensive heating insert is exchanged, but the relatively inexpensive heating box. Quick and cost-effective retrofitting of a tiled stove for producing hot water is thus also possible.
Patent DE-3609481-A1 (DE)
Title: Method and apparatus for the clinch joining by punching of thin plates, especially sheets
Inventor: ZIMMER ERNST
IPC: B21D39/03
Filed: 1986-03-20
Abstract: The invention relates to the clinch joining by punching of thin plates (1, 2), especially sheets. For this purpose, limited areas of the plates are punched out along perforated lines and pushed out of the plane of the plates by an amount corresponding to their combined wall thickness. Squashing the punched-out projections (6) formed in this way gives an interlocking plate joint. According to the invention, the punched-out projections (6) are formed towards the rear side (12) of the plates and squashed by a force opposite to the direction of punching. For this purpose, use is made of the energy derived from an excess motion of the elements (21, 22, 23) which perform the punching operation. In the process, the die (4), into the cavity (5) of which the punched-out projection (6) is deformed, is moved counter to and simultaneously with the pressing movement of the punch. <IMAGE>
