Title: Pneumatic stowing line with front discharge
Inventor: PAWELSKI LUDWIG
IPC: E21F15/08
Filed: 1985-11-27
Abstract: For transporting and placing pneumatic stowing in underground mining, a pneumatic stowing line is provided which in the face area consists of individual pipe sections which have coupling devices arranged at a distance apart. These coupling devices are designed to take up little space and yet are at such a large distance apart that in each case sufficient track widths for the pneumatic stowing to be placed are achieved. The advantageously simple pneumatic stowing coupling, in addition to the annular seals in the front annular grooves, is sealed off via a sealing sleeve. Here, this sealing sleeve is pushed over one of the two pipe flanges and is connected via a fork to the locking piston or the locking device so that, upon engagement of the locking device or its locking pin, the sealing sleeve is advanced and as a result is pressed onto the annular seal accommodated in a front annular groove. Through the simple design and only the single sealing element, namely the annular seal, only slight wear occurs, which in addition can easily be overcome by simple exchange of the annular seal. <IMAGE>

Title: Directional antenna arrangement
Inventor: KANDLER ERICH DIPL ING
IPC: H01Q19/02
Filed: 1986-03-13
Abstract: The undesirable cross-polarisation component at the direction-finding minimum of the difference polar diagram, which is produced by a dipole aerial system (19) in front of a curved reflector (1), can be prevented by the dipoles (15 to 18) which are provided with two straight limbs which enclose an angle of 180 DEG , being rotated as an entity through an angle ss with respect to the actually provided polarisation direction, which angle ss produces additional radiation which is matched in terms of magnitude and phase and largely compensates for the cross-polarisation component. A directional antenna arrangement according to the invention is particularly suitable for use in the case of a secondary radar system which interacts with a primary radar system. <IMAGE>

Title: Electromechanically operated displacement device, especially for opening and closing a motor vehicle window curtain
Inventor: KIMIAIE BAHMAN DIPL ING
IPC: H02K7/06
Filed: 1986-06-28
Abstract: Window roller blinds or window curtains driven by electric motors are being used to an increasing extent as dazzling protection and sun protection in motor vehicles. In order to operate window roller blinds, the pushrod can be coupled to the electric motor in a frictionally engaged or positively locked manner, via a drive device. In the case of the frictionally engaged coupling, the traction cable runs between a friction wheel, which is driven by the electric motor, and a contact-pressure wheel which presses the traction cable against said friction wheel. High contact pressure forces on the traction cable are required in order to reduce the slip, so that, in consequence, large bearing forces are produced and the friction drive can nevertheless be adversely affected by the penetration of dirt during relatively long use. In order to achieve a frictionally engaged drive of the traction cable via a drive device with little slip, said drive device has a second contact-pressure wheel, the two contact-pressure wheels being arranged offset with respect to one another on the circumference of the friction wheel, in such a manner that the path of the traction cable as it passes through the drive device is deflected from a straight line. The shafts of the contact-pressure wheels are guided in a bearing block which is mounted such that it is spring loaded and can tilt. The displacement device can be used widely, for example also for feeding the welding wire in shielded arc welding.

Title: Bonded pole construction for small motor - comprises ribbon wound ring core which is cut and has faces forced apart before consolidating
Inventor: BESTAENDIG NORBERT DIPL ING
IPC: H02K19/10
Filed: 1986-08-19
Abstract: In the manufacture of a pole piece with a ribbon wound core, the core material is wound around a cylindrical former (1) to produce a packet (2). At one position clamps (4,5) are  applied, a small distance apart, and the packet cut through (3). A recess in the former (1) provides the necessary clearance for the cutting operation. The clamped core is then  removed from the former and, by a wedging process, the pole faces produced by the cut (3) are forced apart. The overall core thickness (D) is held constant at the cut faces by the clamps (4,5), but is allowed to extend gradually to a larger dimension (D2) at the mid point of the core. Injecting and curing a resin sticker then consolidates the core laminations and the clamps are remvoed. To reinforce the free ends (3) the faces can be machined to produce a number of narrow slots in which fibre filled resin is inserted and cured. ADVANTAGE - Eliminates need for making and assembling specially formed laminations.

Title: Arrangement and method for identifying displacement of the internal layers of multilayer printed circuit boards
Inventor: MERKENSCHLAGER HANS-HERMANN DI
IPC: H05K3/46
Filed: 1986-12-16
Abstract: The invention relates to an arrangement and a method for identifying displacement of the internal layers of multilayer printed circuit boards before the through-plated holes are drilled, by means of copper test tallies outside the printed circuit board blank's contour. In this case, the invention proceeds from the fact that, in the case of a known method, each printed circuit board core has at least one test tally, as well as the conductor pattern, which, in production-engineering terms, is a component of the conductor pattern, the test tally consisting of a strip of electrically conductive foil in which an etched-free trench is arranged. The respective electrical contact between the drill and the internal layer is then determined, with respect to a reference point, by means of staggered test holes in the centre of the etched-free trench in the test tally, and the position of the test holes is then electrically interrogated. However, particularly in the case of multilayer printed circuit boards with a large number of layers, this leads to a large test outlay since a dedicated display instrument must be used for each layer. In contrast, the present invention achieves the object in that the test tallies are copper surfaces which have at least one edge (measurement edge) which runs at a predetermined angle, preferably at right angles to the direction in which the displacement of the internal layer is intended to be tested, the measurement edges in all the internal layers being disposed from the same point. The evaluation is in this case carried out optically. <IMAGE>
Patent DE-3643724-A1 (DE)
Title: Strain gauge
Inventor: LECHNER KARL
IPC: G01B5/30
Filed: 1986-12-20
Abstract: Strain gauges having two sensors which are spaced apart are equipped with sharp blades and are pressed against the material sample. The shape and arrangement of the prior blades entail a high outlay on assembly and errors in measurement. The new gauge, by contrast, permits simple assembly and exact measurements without the risk of slippage of the sensors. The sensors are provided with two blades arranged in a V-shaped fashion, with the result that a self-centring, nonslip two-point contact is achieved between the sensors and material sample. U-bolts which draw the blades against the material sample by means of tension springs are suspended near the blades in order to apply the contact pressure. The strain gauge is suitable for measuring strains and displacements of material samples, in particular at very high temperatures.
