Title: Multi-layer wall for a safe
Inventor: HERMANNS HORST
IPC: E05G1/024
Filed: 1981-06-12
Abstract: The invention relates to a multi-layer wall for a safe with an outer wall and inner wall made of concrete and with an intermediate wall made of a filling arranged between metal sheets and having bodies of hard material embedded therein, the outer wall and inner wall being connected to one another by means of ties. In order to improve the break-in safety of a wall of this type, the bodies embedded in the filling (6) of the intermediate wall (3) are made multi-part, namely from bell-shaped inner caps (9), which are welded at their free edges to the metal sheet (5) of the intermediate wall (3) facing the inner wall and onto which rotatable outer caps (10) are attached on the side facing the outer wall. The filling (6) of the intermediate wall (3) preferably consists of a foam material which makes no connection with the outside of the outer caps (10), so that, when a drill strikes an outer cap (10), the latter is taken up by the drill and further drilling work is no longer possible. <IMAGE>

Title: Spinning machine with drafting units
Inventor: BARTLING GERHARD ING GRAD
IPC: D01H13/18
Filed: 1981-09-19
Abstract: In a spinning machine with drafting units for high delivery speeds, such as are used, for example, in wind-round spinning processes, the lower rollers (3) are assigned individual upper rollers (14) which are held in links (11), which are under spring force (12), by supporting and load arms (8) arranged pivotably and lockably in stays (7). Each stay is fastened on a supporting-rod portion (6) which is mounted rotatably on the machine and which can be rotated by an associated adjusting means (16) into a load position for the upper rollers (3) and into a position lifting them off from the lower rollers (3). The adjusting means (16) is switched, by means of a monitor (32) assigned to the material (31) running out of the drafting unit, in such a way that, in the event of a material break, the adjusting means (16) rotates the supporting-rod portion (6) out of its load position for the upper rollers (14) into the position lifting them off from the lower rollers (3) and at the same time switches on a clamping device (36) assigned to the roving (131) at the entrance of the drafting unit. Favourable preconditions for repiecing are thereby afforded. <IMAGE>

Title: Method for determining the quantisation distortions of transmission devices, particularly for PCM
Inventor: SCHWARZ CHRISTIAN DIPL ING
IPC: G01R23/20
Filed: 1981-11-17
Abstract: In this method, a quasi-stochastic noise signal is used at the transmitting end and the noise signal and the signal components produced by distortion are evaluated in two measuring branches at the receiving end. To achieve a short measuring time with high accuracy of the measurement signal, the quantisation distortion is determined in three measuring phases by means of a quotient analog/digital converter QAD, after the signal components Az(t), An(t) have been integrated together in the two measuring branches, the quantisation distortion is determined from the reverse-integration time by reverse integration of the output variable Ana(t) of the second integrator IN as reference variable. The invention can be mainly applied in the testing of telephone lines. <IMAGE>

Patent DE-3148924-A1 (DE)
Inventor: LUGTIGHEID ARNOLD
IPC: A22C15/00
Filed: 1981-12-10
Abstract: Heretofore, the loops for the transport of meat were made with a string which was passed through the meat of which the end was suspended to a hook. The industrial treatment of this type of transport loops creates frequent and serious problems of the knotting machine caused by clogging upon passage of the loop through the meat. The transport loop according to the invention is made of relatively resistant and smooth plastic material and the lower portion of the loop has at least one lateral protuberant support portion (10), so that an independent passage of the loop portion and a subsequent connection of both portions are not required anymore. To this aim, the support portion (10) is integrally connected to the upper portion (5) of the loop and is arranged into a rigid element perpendicular to the main direction of the loop so as to prevent any sliding of the loop through the meat, respectively outside the meat.
Patent DE-3149002-A1 (DE)
Title: Device for delivering and discharging objects stored in racks
Inventor: JAGOB KARL
IPC: B66F9/18
Filed: 1981-12-10
Abstract: The invention relates to a device for delivering and discharging objects, such as containers, from racks by means of a movable and arrestable conveyor. Normally fork-lifts are used here, onto the supporting plate of which the objects to be transported in each case are pushed by hand. This activity is strenuous and also not altogether safe, because the objects often have to be pushed across the gap distance, the supporting plate and racks. According to the invention, the delivery and discharge of the objects can be facilitated and permitted largely without accident if the conveyor is provided with a liftable and lowerable bearing block to which an oscillating pair is linked at the end, to the other free end of which a support suitable for taking hold of the objects is fastened. With an oscillating pair of this type, virtually any point inside the rack can be reached and then, when the objects are attached to the supports, the conveyor can be actuated without the objects having to be lifted or displaced by hand.

Title: Device for fastening the upper deflection fitting for a three-point safety belt to the body of a motor vehicle
Inventor: KLUETING BERND ING GRAD
IPC: B60R22/20
Filed: 1981-12-23
Abstract: A device for fastening the upper deflection fitting for a three-point safety belt to the body of a motor vehicle has a metal profiled rail which is to be connected to the body, a slide guided in the profiled rail so as to be longitudinally displaceable, with a connecting element making the connection between the slide and the deflection fitting, and a locking device for securing the slide in the selected position. Notches are provided at a distance from one another in the profiled rail in the longitudinal direction of the latter for the engagement of two blocking elements which are actuable by means of an actuating member. The width of the notches (8), as measured in the longitudinal direction of the profiled rail (2), is larger than the width of the blocking elements (18), as measured in the same direction. Moreover, the latter are mounted in the slide so as to be offset in the longitudinal direction of the profiled rail (2) to such an extent that, in any position of the slide (9), at least one of the two blocking elements (18) is aligned with one of the notches (8) and can engage into it. <IMAGE>

Title: Clamping device for flexible data media
Inventor: LANSSKY SIEGFRIED
IPC: G11B17/028
Filed: 1982-01-22
Abstract: The invention relates to a clamping device for flexible data media in disc form, the clamping element of which comprises spring arms which are arranged rotationally symmetrically about a pin and have centring faces and bearing faces for the frictional carrying along of the data medium. What is essential about the invention is that the spring arms are provided in alternating sequence on the one hand just with centring faces and on the other hand with faces without any centring function and with bearing faces for the frictional carrying along of the data medium, the radius of rotation of the centring faces being greater than that of the faces without any centring function. As a result, the ending of the centring of the data medium takes place by means of spreading open the spring arms already before the beginning of contact being made by the bearing faces with the data medium for the frictional carrying along of the latter.

Title: Regenerative heat exchanger of a gas turbine
Inventor: KINAST KARLHEINZ
IPC: F28D19/04
Filed: 1982-03-12
Abstract: The heat exchanger disc of a regenerative heat exchanger for a gas turbine consists of a ceramic material. Arranged in an annular space between the rim of the heat exchanger disc and a metal toothed rim surrounding the latter coaxially at a distance are leaf spring elements which are each supported with end sections on the inside of the toothed rim and with a convex centre section in a depression, which is concave in longitudinal section, on the top side of a driver plate. Said elements are each situated with a curvature which is convex in cross-section on a concave depression extending in the circumferential direction on the rim of the heat exchanger disc. The underside of each driver plate and the rim of the heat exchanger disc are each provided with an adhesive layer. The shape of the driver plates produces a favourable transmission of the spring forces and, in cooperation with the adhesive layers an effective and gentle transmission of the driving torque on to the heat exchanger disc, which is sensitive with respect to mechanical loads.
