Title: Holding device for pneumatic screwdrivers
Inventor: SMEETS HORST
IPC: B25H1/00
Filed: 1983-06-25
Abstract: A holding device for pneumatic screwdrivers has a telescopic support which can be suspended from a fixed carrier via a universal joint and the free end of which carries a hydraulically actuable clamping holder for the cylindrical front end of the screwdriver casing. The telescopic support furthermore contains a valve device located in the compressed-air supply of the screwdriver, and a hydraulic pressure generator capable of being acted upon pneumatically and intended to provide the actuating pressure of the clamping holder. In this arrangement, the valve device is designed so that, when the screwdriver is switched on, the said valve device first frees the compressed-air supply to the pressure generator and only then to the screwdriver. The holding device is particularly suitable for ordinary screwdrivers which generate the necessary torque without impact.

Title: Direction-finding receiver with several direction-finding channels
Inventor: BREITSCHAEDEL ROBERT DIPL ING
IPC: G01S3/02
Filed: 1983-07-21
Abstract: In a direction-finding receiver with several direction-finding channels, an analog/digital converter is arranged in each direction-finding channel, the sampling of the signals in the various direction-finding channels being synchronised by a central clock generator. Each direction-finding channel also contains at least one digital filter. The filter coefficients are identical in the different direction-finding channels and are advantageously adjustable as determined by a desired filter characteristic from several selectably predetermined characteristics. The signals present in digital form enable calibration measures to be carried out in a particularly advantageous manner for calibrating synchronisation errors in analog modules of the direction-finding receiver. A microprocessor is preferably arranged in each direction-finding channel for carrying out the filtering and calibration. Another processor handles, among other things, the control of the data and the synchronisation of the clock pulses in the different direction-finding channels.

Title: Angle-measuring instrument for pluggable, rectangular frames (e.g. windows)
Inventor: STUDENT HOLGER
IPC: G01B3/14
Filed: 1983-09-08
Abstract: In order to check the rectangularity in pluggable, rectangular frames, the goniometers of the two angle-measuring instruments, which are attached to a guide rail running diagonally over a frame to be set up rectangularly, are pressed by means of spring force into the diagonally opposite frame corners. Even when the angle-measuring instruments are fixed, the horizontal mobility of the goniometers permits a change in length of the diagonals of the frame without adjusting the angle-measuring instruments on the guide rail. In order to achieve the highest possible accuracy in determining a deviation from an angle of ninety degrees, the goniometers can be exchanged for goniometers having longer limbs. The seating of the angle-measuring instruments on the frame to be set up rectangularly is designed such that a minimum frame width of only two centimetres is required.

Title: Device for detecting the movement and/or position of a pivotable door leaf
Inventor: GUDAT WOLFGANG
IPC: E05F15/53
Filed: 1983-09-14
Abstract: In a device for detecting the movement and/or position of a pivotable door leaf, for example for a door control in a means of public transport, a sensor is arranged in the region of an axis of rotation of the door leaf. The sensor serves for detecting the rotational movement between the door leaf and a part which preferably serves as a pivoting lever for the door leaf and which is also pivotable about the axis of rotation in the region of which the sensor is arranged. During a pivoting of the door leaf, said axis of rotation for the door leaf and for the pivoting lever is likewise pivoted. A relatively large rotary angle detected by the sensor is thereby obtained.

Patent DE-3412910-A1 (DE)
Title: Device for locating vehicles
Inventor: WILMS GERHARD DIPL ING
IPC: B61L25/02
Filed: 1984-04-05
Abstract: In a track conductor with centre conductor and outer conductor which meanders with respect to the latter, there is provision to lay the centre conductor (for example L1) as outer conductor and the outer conductor (L2) as centre conductor in successive sections (S1, S2) of the route. As a result, the conductor track arrangement is made symmetrical from section to section, the said symmetry leading to an approximately linear progression of the signal voltage over the route. This measure permits the length of the conductor track arrangement to be operated from a route control centre to be increased considerably with respect to an arrangement without symmetry. This is particularly significant at high signal frequencies because, here, without the symmetry according to the invention only a very irregular voltage characteristic over the track conductor can be detected. By means of an additional reception coil to be coupled to the respective centre conductor and comparative evaluation of the reception voltages introduced in the coils coupled to the central conductor(s), the passage through route section boundaries can be detected on the vehicle and thus the vehicle can be located with absolute precision. <IMAGE>

Patent DE-3417053-A1 (DE)
Inventor: REIST WALTER
IPC: B65H29/58
Filed: 1984-05-09
Abstract: An imbricated product subformation is formed from one half of the printed products delivered in an imbricated product formation by a conveyor or transporter. This subformation is guided through a deflection or turning device. The printed products are accelerated and separated or singled as they run through this deflection or turning device and are simultaneously inverted. After leaving the deflection or turning device, the printed products are conveyed against a fixed stop member and are then deposited upon a belt conveyor to form a new imbricated product subformation. A second subformation is formed from the other half of the arriving printed products and is deposited upon the first altered subformation and is then conjointly wound up with this first altered subformation to form a coil or wound product package. By dividing the initially arriving imbricated product formation into two subformations and subsequently reuniting these subformations, the winding operation can take place at a speed which is only half as great as the delivery speed of the initially arriving imbricated product formation.

Title: Springs for seating furniture, in particular seats of motor vehicles and means of public transport
Inventor: PAULISCH HEINZ
IPC: A47C7/24
Filed: 1984-05-14
Abstract: Springs for seating furniture, in particular the seats of means of public transport consist of upper springs and lower springs, the upper springs being formed by form wire spring sections. The form wire spring sections of the upper springs are bent back downwards in a direction running transversely to the crank deflections, the lower springs likewise consisting of form wire spring sections which are each clipped individually in each case to one of the form wire spring sections of the upper springs and whose ends are attached to the seat frame independently of the sections of the upper springs. The spring sections of the upper springs are guided freely, i.e. without being clipped together or to the seat frame. The free ends of the form wire spring sections of the lower springs directed towards the rear seat edge are straight, whereas the ends of the form wire spring sections of the lower springs directed towards the front seat edge run in a zigzag shape up to their attachment point. Finally, the sections of the lower springs are clipped to the sections of the upper springs at the longitudinal branches on one side of the crank deflections and the dimensions are conceived in such a way that the free longitudinal branches of the form wire spring sections of the lower springs engage below the crank deflections of the spring sections of the upper springs in each case at a transverse branch.
