Patent DE-3222257-A1 (DE)
Title: Tension, compression or tension-compression spring which can be loaded axially
Inventor: FEDERN KLAUS PROF DR ING
IPC: F16F1/18
Filed: 1982-06-09
Abstract: The tension, compression or tension-compression spring according to the invention consists of a rod profile or flat profile, between whose straight axial clamping-in ends there is a region with multiple corrugations, and the corrugation is constructed such that, when the tension or compression stress is introduced, the quotients  Mb(z)/[E l (z-1)] which are applied along the neutral fibres in the corrugated spring part, locally as vectors at right angles to the longitudinal section plane of the projection (where Mb(z) is the local bending moment produced by the external tension or compression forces introduced as spring longitudinal forces, and E l (z-1) is the local longitudinally-related bending stiffness about the neutral fibres in the respective cross-section) form no resultant but only a moment about the longitudinal axis between the end points of the free spring length. The spring, which has not yet become known in this form, can be clamped in entirely, or at least largely, without any moment and not only can its flexibility be adjusted over a wide range at a small production-engineering cost, but, because of the shape-specific transverse deflections of the corrugated bends under load, can be used directly for damping and cancellation.

Title: Device for processing goods identification cards
Inventor: BRUENE BERNHARD
IPC: G06K13/02
Filed: 1982-06-25
Abstract: To check the goods turnover, the movements of goods and material and goods values, these are provided, when they are received, with identifications to which first the necessary data are applied, for example with the aid of a recorder belonging to a data processing system. The identifications or check cards are read by machine and evaluated on delivery or sale or in other situations such as, for example, stocktaking. For this purpose, identifications having separable check cards are preferably used, which are separated at each intermediate station, sorted and then read. For this purpose, a device is provided in which the check cards are collected and are then individually passed underneath a reader and read. To protect the individual check cards and to facilitate filing, cassettes for receiving or catching the individual check cards are provided in the collecting hopper and at the end of the housing of the device. Misreadings are avoided by allocating signal transmitters to the read head and a stopper consisting of separating part and trigger. This stopper pushes a separating part between the isolator and the last card so that this can no longer be delivered. <IMAGE>

Title: Infinitely variable vertical adjustment for a seat belt
Inventor: BIEBER HANS-GUENTER
IPC: B60R22/20
Filed: 1984-02-23
Abstract: In order to attach a loop which is fastened to a door pillar, principally of a motor vehicle, for the purpose of receiving a continuous seat belt, it is proposed to make this loop vertically adjustable. For this purpose, the loop is connected by means of a bolt (h) to a spring packet (f) which is vertically adjustable in a housing (a). Two spring platelets (e) which point to the outer faces of the spring packet (f) are convexly shaped and rest against the inner faces of the housing (a). They lock the vertical adjustment of the belt loop. When a seat belt is subjected to tensile stressing in the direction of travel, the spring packet (f) blocks the vertical adjustment. The vertical adjustability is infinite, that is to say without ratchets. <IMAGE>
