Title: Circuit arrangement for a telephone subscriber station with a DTMF (multi-frequency) transmitter
Inventor: MOSES KLAUS DIPL ING
IPC: H04M1/50
Filed: 1985-02-08
Abstract: In a telephone subscriber station, the DTMF transmitter is connected via a control amplifier to the modulator which adds the AC voltage signal generated by the DTMF transmitter to the DC voltage present between the speech wires. The output signal of the control amplifier is monitored by a level comparison device; as soon as the signal has reached a pre-defined value, the level comparison device instigates the closure of the switching means looped in between the output of the control amplifier and the input of the modulator. It is thus ensured that, firstly, independent of the level of the DTMF signal at the output of the DTMF transmitter, the prescribed transmission level is maintained on the speech wires a/b with the aid of the control amplifier and, secondly, it is ensured by means of the level comparison device and the switching means that the DTMF signal is not forwarded to the speech wires until the transient responses in the control amplifier have died down, i.e. that the signal is immediately applied at full level to the speech wires.

Patent DE-3506841-A1 (DE)
Inventor: HERB ARMIN
IPC: F16B13/10
Filed: 1985-02-27
Abstract: An expansion dowel includes an axially extending expansion sleeve and an expansion member rolled from a section of sheet metal. The sleeve has a leading end and a trailing end and the inside surface of the sleeve is threaded for an axially extending section from the trailing end. The thread is formed before the sheet metal is rolled. To assure there is no misalignment of the thread along the butt joint, tangs and recesses are formed along the edges of the butt joint so that the edges interengage one another when the sheet metal section is rolled. By interengaging the butt joint edges, the sleeve does not expand circumferentially when a bolt is threaded into the trailing end of the sleeve.
Patent DE-3513583-A1 (DE)
Title: Capacitive sensor
Inventor: HEBER KURT DR ING
IPC: G01D5/24
Filed: 1985-04-16
Abstract: Capacitive sensors for gaseous measurands conventionally consist of a pair of fixed capacitor plates between which the measurand is introduced in a parallel flow. If they are required to contain an auxiliary medium which has to react to the measurand in order to allow a capacitive measurement, they often have a porous electrode which permits diffusion processes into the auxiliary medium. An open measuring capacitor having a fixed electrode 4 and at least one electrode 3 which is readily permeable to the gaseous measurand, does not require any flow and is considerably less sensitive to contamination. The electrode 3 can be produced in a simple manner on a metallic or metallised mesh or woven material. It is able to undertake further measuring tasks at the same time. A further electrode 13 of the same type protects the sensor mechanically and electrically. <IMAGE>

Title: Quick-acting fluid valve
Inventor: KARUBIAN RALPH
IPC: F16K31/383
Filed: 1985-06-13
Abstract: A valve for fluids such as, for example, air has an inlet and an outlet connection body, a hollow cylindrical tube running between them, and an insert which is arranged in the tube between the inlet and outlet connection, has an inlet opening and an intermediate chamber and carries a control valve. The cylindrical main valve body is arranged coaxially in the intermediate chamber; it has a flat end face facing the control valve and is tapered towards the outlet connection, an annular groove with a pressure surface being provided in the tapered end. Furthermore, the tube contains an outlet closure section through which the air or the other controlled fluid can flow out of the intermediate chamber via passages in the insert into an entry area of the outlet connection body. The entry area is shaped in accordance with the tapered part of the main valve body so that the air or fluid, acting under pressure from the intermediate chamber on the annular pressure surface, forces the main valve body into the open state, whereas the pressure on the far larger end face of the main valve body forces the latter into the closed position until this pressure is removed as a result of actuation of the control valve so that air or the fluid can escape from the end face of the main valve body to the atmosphere, and the force acting on the annular pressure surface of the tapered end of the main valve body ... greater than the ...

Title: Measuring arrangement with a multiplicity of measuring units
Inventor: MEHNERT WALTER DIPL ING DR
IPC: H01B7/08
Filed: 1986-07-07
Abstract: The measuring units (5) of a measuring arrangement are combined to form groups (16 to 22) having in each case a selection unit (25). A cable (1), into which the measuring and selection units are integrated, connects the latter to one another and to a central station (2) which, by sending out address signals, individually activates the selection units so that the latter prepare the measuring units of their group for the reception of measuring unit address signals from the central station. The address signals in each case consist of pulse sequencees which are decoded by programmed receiving circuits. The pulses for the measuring units differ from the pulses for the selection units by their length in time. The sensors (10) used are current sources which, when their measuring station is selected, are connected to a voltage supply and thereupon impress a measuring current, which is variable with the quantity to be measured, on a measuring line wire (7) of the cable which leads to the central station. The measuring and selection units comprise current limiting and buffer circuits (32) which limit short-circuit currents and even out the current loading on the cable. Signal shaper circuits (30) in the selection units condition the pulses and feed them into the next line sections. <IMAGE>

Title: Material lock with subdivided resettable sealing plates
Inventor: BLANKMEISTER WILHELM DR
IPC: B65G53/46
Filed: 1986-09-29
Abstract: In the case of a material lock, the sealing plates are divided in the circumferential direction into two regions (6, 7 and/or 8, 9) which are sealed off (11) from one another. This ensures that when the inside (3) and outside (4) of the cellular cylinder wall are subjected to different levels of wear, the sealing plate can be adapted to this and can be reset by different amounts. To ensure that the radial spokes (5) of the cellular casing (2), which are not subjected to a high degree of wear per se, do not tend to have a supporting action and prevent resetting of the outer sealing plates (6, 7), the said spokes (5) have points which are intended to be subjected to wear, which take the form of lips (14) in this case. <IMAGE>
