Patent DE-3030793-A1 (DE)
Title: Lift or elevator speed and braking control - is by comparison of tachometer signal against reference signal for all loading conditions
Inventor: GRAY JOHN EDWARD
IPC: B66B1/34
Filed: 1980-08-14
Abstract: The speed or braking control is for lifts or elevators. The control system ensures that braking and speed is regulated despite loading changes. Loading is determined by a tachometer (30) on the lift motor (10). This is compared continuously with a reference signal (REF) the reference representing maximum speed for a maximum load descent and minimum load ascent. The difference (DIF) between the two signals controls a delay to the transmission of brake and/or slow signals to the motor as pick-up stations are approached. The reference and tachometer based signals are synchronised by an input to the reference source (18). The difference output from a substraction circuit (10) is fed to two delay circuits (20, 22). These have further feedback inputs from braking (26) and stop (28) signal generators (SLOW, STOP) directly controlling the lift motor.

Patent DE-3106947-A1 (DE)
Title: Winding apparatus for winding up flat threads to form cylindrical cross-wound bobbins
Inventor: SCHIMINSKI WERNER
IPC: B65H57/16
Filed: 1981-02-25
Abstract: What is proposed is a precision cross-winding apparatus (1) for flat threads, especially slit film yarns for carpet base fabrics and the like, in which at least two flat threads (2, 3) can be wound with a predetermined overlap on a bobbin tube clamped by a winding spindle. As a result of the special construction of the traversing thread guide (11), it is possible considerably to reduce the number of winding apparatuses (1) in an installation for slit film yarn and therefore also the investment costs. According to the invention, the traversing thread guides (11) are of two-part design and can be adjusted for different widths of slit film yarn and for a selectable overlap. The bobbins (4) produced on the winding apparatus and having partially overlapping slit film yarns (2, 3) are highly suitable for the feed in a warping creel for warp-beam production. The bobbins (4) can be worked off without difficulty and can easily be transported, since the thread layers can no longer slip off on the bobbin edges, but retain one another. <IMAGE>

Title: Process for producing profiles, and apertaining composite profile
IPC: E06B3/36
Filed: 1981-07-17
Abstract: An extruded section for forming heat-insulated door frames, window frames and the like is composed of a hollow aluminium profile (2, 2') which forms the facade side and constitutes the carrier for all the mechanically loaded fittings, anchorings and the like, and of an essentially non-load-bearing plastic profile (3, 3') which forms the room side and is connected to the hollow aluminium profile (2, 2') by parts, such as grooves and strips, which engage one in the other or one behind the other. In order to achieve, with the same measures, a good heat insulation and a good grip of the profiles on one another, the plastic profile (3, 3') forms, with the hollow aluminium profile, a hollow chamber which is filled with a foamed plastic (12). The foamed-plastic filling, being supported on the two profiles (3, 3' and 2, 2'), fixes and clamps (or braces), and adhesively bonds, said profiles with respect to one another and, furthermore, the foamed-plastic filling engages between or behind the connecting parts of the two profiles (3, 3' and 2, 2') and likewise fixes these with respect to one another and bonds them adhesively. <IMAGE>
