Patent DE-4305149-A1 (DE)
Title: Displacement-compensating load sensor
Inventor: LAUNHARDT GEORG
IPC: F16L3/20
Filed: 1993-02-19
Abstract: The load sensor is used for the stationary sensing of uniform loads which are moved by external influences such as, for example, expansion through temperature change or controlled level changes for height compensation at processing machines and transport equipment. The problem of the invention consists in creating a load sensor with force-compensating curve guidance of a spring, which load sensor has small dimensions and a low weight, a large load-dependent adjusting range as well as low friction losses and thus high functional reliability. According to the invention, the problem is solved by virtue of the fact that a spring (3) located in the load-sensor housing (2) is loaded by means of a supporting element (8) such as a cable or band via a circular-segment part (7) and a lever rail (6) located on it, the pressure point of the spring (3) being guided by means of a sliding piece (4) or roller along a guide curve on the guide-curve part (5). The symmetrical design of the load sensor according to the invention, as a result of a favourable load distribution, permits a dead-weight reduction of about 50% as against comparable embodiments of load sensors. <IMAGE>

Title: Method and arrangement for semi-and fully-automatic completion and mounting of the caps, springs and in particular additional, integrated extendable hangers for Christmas-tree balls, which cover the blowing opening and are used for hanging, and modified forms
Inventor: STROBEL FRIEDRICH
IPC: A47G33/10
Filed: 1993-05-18
Abstract: The mounting of the caps for covering the blowing opening and attachment of a hanging loop on Christmas-tree balls, and modified forms, are still predominantly carried out by hand. Semi-or fully-automatic mounting devices require a high outlay for the separation/sorting of the unstable components, some of which are three-dimensional, the outlay for the additional equipping with extendable hangers being even considerably greater. Through the method according to the invention of loading the mounting device with magazined, merely initially worked caps, springs and, if necessary, extendable hangers or merely with their semi-finished products and of effecting completion immediately before mounting, the complicated part of the feeding work is dispensed with, while the required precision, e.g. for the optimal hanging point of the extendable hanger, is necessarily achieved.

Title: Push-in system for roller-blind-casing covers
Inventor: PASCHKE THOMAS
IPC: E06B9/17
Filed: 1993-08-21
Abstract: Roller-blind-casing covers may be fabricated from various panel materials. In particular in the case of sandwich panels with a polyurethane rigid-foam central layer and in the case of covers which can be painted or wallpapered, it is inappropriate to place the screw-connections on the front side. In the case of the polyurethane rigid-foam panel, a depression is produced in the region of the screw-connection and, in the case of a cover which can be painted, the paint or the wallpaper is damaged when the cover is opened. In order to overcome the problem with the cover screw-connection, the cover is held at the top by an angle and is fastened at the bottom by an angle profile. The screwed top and bottom angles ensure that the cover is pressed, over the entire length, onto the sealing strip. The receiving angle at the top is suitable for receiving all panel materials and panel thicknesses. <IMAGE>
