Title: Circuit arrangement for setting up toll-free connections for the calling subscriber
Inventor: NIEGEMANN RICHARD ING GRAD
IPC: H04M15/08
Filed: 1981-02-26
Abstract: For setting up toll-free connections for the calling subscriber to specific subscribers by dialling a special service number followed by a number which identifies the pre-defined subscriber connections and which is converted into the telephone number of the assigned subscriber connection, a coding device (CE) is used which is connected and operated in a known long-distance dialling system the same as a meter pulse transmitter (ZIG). As is known, these devices are disposed in the node switching centre. On the basis of the special service number, the conversion device (UM) initiates the connection of the relevant connection line to a free coding device (CE). The latter converts the subsequently dialled number into the telephone number of the relevant subscriber connection and transfers this in the same way as a meter pulse transmitter (ZIG) to a register (RG). The further connection set-up is carried out in a known manner. On the basis of an instruction from the conversion device (UM), the meter pulse transmitter (ZIG) disposed in the connection transmits no meter pulses to the calling subscriber, instead of which the charge calculation is carried out in the coding device (CE) or in a special metering device (Z) on a time and zone-dependent and subscriber-individual basis.

Title: Process for producing moulding material boards during the course of production of chipboards, fibreboards and the like
IPC: B27N3/20
Filed: 1981-05-16
Abstract: The invention relates to a process for producing moulding material boards which have the same board thickness throughout within a close tolerance during the production of chipboards, fibreboards and the like from continuously scattered moulding material mats in board presses having a closed-loop board thickness control circuit. The actual values of the board thickness are measured by means of a measuring device. They are compared in a controller with a predetermined set value. Depending on the set value/actual value difference, correcting devices associated with the board press, for thickness control, are actuated by the controller. The actual values of the board thickness are measured on the one hand in the longitudinal centre of the moulding material boards, on the other hand in the region of the longitudinal edges of the moulding material boards. An integrated computer is used to form from the sum of the edge actual values an edge actual value mean value and to form from the sum of the centre actual values a centre actual value mean value. The two edge actual value mean values are for their part converted into an edge actual value mean. The edge actual value mean is compared by means of a measured-value comparator with the centre actual value mean value. The result is that a statistical actual value related to the board edges or board centre is formed. This statistical actual value is compared in the controller with the set value - and thereafter the control circuit continues to operate as usual. <IMAGE>

Title: Measuring device for testing shock-absorbing legs in the front-wheel suspension of vehicles
Inventor: NILSSON LARS-ERIK
IPC: G01M17/04
Filed: 1981-06-24
Abstract: The measuring device consists of a stand (12) which is attached to a lower component (14, 20). The lower component can be attached to the outside of the brake disc (40) with the aid of permanent magnets (24, 26). A measuring arm (30) is attached to the stand (12) in a movable fashion and is equipped a longitudinal scale and projects from the stand (12) in such a way that it forms a right angle with the plane of the brake disc (40). This arm bears a movable pointer (36) with which the centre point (60) of the upper attachment (55) of the shock-absorbing leg (50) in the body of the vehicle can be searched for. After this setting, the vertical distance (a) from the centre point (60) to the plane of the brake disc (40) can be read off on the scale of the measuring arm (30). When this distance is known, it is possible to judge whether the shock-absorbing leg (50) is deformed or not. <IMAGE>

Title: Device for producing packaging sleeves
Inventor: SAUR WALTER
IPC: B31F1/00
Filed: 1981-06-30
Abstract: A device is proposed with a shaping mandrel (20) for producing packaging sleeves (10) of blanks of packaging material. So that the shaped sleeves can be easily drawn off the shaping mandrel, one of the side walls of the latter is initially arched, so that the sleeve no longer rests tightly against the shaping mandrel when this side has returned to a single plane. To achieve this, the shaping mandrel has a concave side (29) against which the blank is placed, while the longitudinal seam (14) is being formed, by means of a roller (27) which can be pivoted about a pivoting point. <IMAGE>
Patent DE-3126867-A1 (DE)
Title: Single-channel direction-finding method with automatic correction of bearing errors
Inventor: FAST PETER
IPC: G01S3/14
Filed: 1981-07-08
Abstract: According to the invention, the accuracy of the direction-finding results, which are achieved with single-channel direction finders operating in accordance with the Watson-Watt principle, are improved by the fact that the deviation of the calibration direction-finding result from the nominal bearing angle is quantitatively determined in a repeated calibration process and used for automatic correction of the direction-finding result. For this purpose, the bearing values produced are converted into a digital form and supplied to a storage and computing unit; the corrected direction-finding result determined by the latter is then indicated. The method can also be used when the receiver is more severely detuned. The only prerequisite is that the amplitudes at the receiver output are sufficient for further processing in the memory and computing unit.

Title: Device for mounting a tool on a drive spindle
Inventor: WOZAR TIBERIUS
IPC: B23B31/113
Filed: 1981-07-23
Abstract: A quick-acting gripping device for mounting a tool shank on a drive spindle (22) is specified. The tool shank has a radial gripping flange (12) which can be axially clamped in place between the end face (20) of the spindle end and gripping dogs, set back radially to the inside, of a clamping ring (54). The said gripping dogs, together with gripping dogs (14) of the gripping flange (12), form a bayonet catch. The clamping ring (54) carrying the rotatable gripping dogs is connected via an axial bearing to the threaded ring (46) for producing the axial gripping force. A stop means (72, 78, 80) ensures that the clamping ring can assume an open position, in which the gripping dogs (14) of the gripping flange are in alignment with the intermediate spaces between the gripping dogs of the clamping ring, and a closed position in which the gripping dogs of the gripping flange (12) and of the clamping ring (54) are in alignment. To move the clamping ring (54) between these two end positions, an overrunning clutch is provided which has a clutch ball (86), the diameter of which is greater than the axial dimension of a clutch bore (84) of the clamping ring (54) and which can be moved by a stationary cam face (76) into a clutch bore (88) of the threaded ring (46) when this clutch bore (88) is in alignment with the clutch bore of the clamping ring. <IMAGE>

Title: Cleaning and filling machine for barrels with two different diameters
Inventor: WALL HANS-JUERGEN DIPL ING
IPC: B08B9/08
Filed: 1981-12-04
Abstract: The invention is a cleaning and filling machine (1) for barrels (5, 6) with two different diameters (11 and 8, respectively), by means of which machine the barrels (5, 6) which are drawn off by a roller conveyor (14) are treated with their tops pointing downward on at least one treatment lane (1a to c) with a plurality of treatment heads (3). The thick barrels (5) which occur infrequently cannot be processed on a standard machine (1) as the only type because their spacing (4) is dimensioned to be substantially larger than the small barrel diameter (8) but smaller than the large barrel diameter (11), in each case plus a safety distance (9). By using the known alternating processing of thin (6) and thick barrels (5) on a standard machine (1) even thick barrels (5) can be treated on it. At the same time, a thin (6) and a thick barrel (5) are alternately called up from separate preprocessing lines (12, 13) by means of a switching device (15) which is assigned to the first treatment head (3a) and responds to the barrel diameter (8 or 11). With a very low occurrence of thick barrels, only one common preprocessing line may also be provided, in which case either an empty space or a thin barrel follows a thick barrel in the treatment line. <IMAGE>
