Patent DE-3726715-A1 (DE)
Title: Device with a gathering-type slatted blind
Inventor: NEUKOM HANS
IPC: E06B9/32
Filed: 1987-08-11
Abstract: The gathering-type slatted blind can be lowered and raised by rotating a winding drum (37) and unwinding or winding up a band-type pulling element (9). The winding drum (37) is coupled, via sliding-clutch means (61a, 63), to a pivot element (61) which can pivot about the rotary axis (13) of the shaft (15) and by means of which the slats of the gathering-type slatted blind can be pivoted when said blind is lowered and raised. An intermediate pivot position for the slats can be fixed by means of a stop of the pivot element (61) and a locking member (51) which is retained movably in a stationary housing (23). A generally U-shaped triggering means (41) which can be controlled by the pulling element (9) has two legs (41a, 41b), which are guided such that they can be displaced radially with respect to the rotary axis (13) in the side walls (33b, 35b) of the winding drum (37), and a portion (41c) which connects said legs, in the form of a web and on which a helical spring (43), pressing the triggering means (41) away from the rotary axis (13), acts. When the triggering means (41) is pushed by the helical spring (43) into its outer displacement position, it can, on the rotation of the winding drum (37), displace the locking member (51) temporarily into a release position in which said locking member releases the stop which fixes the intermediate pivot position. The device permits disruption-free pivoting of the slats and can be cost-effectively produced. <IMAGE>

Title: Selective cooling device on a tool holder of a machine tool which offers a choice of additional machining means
Inventor: BERGER ZOLTAN
IPC: B23Q5/00
Filed: 1987-11-19
Abstract: This selective cooling device not only provides a simple and effective solution to cooling and lubricating problems on machine tools, but also permits additional means of machining workpieces. The object of the invention is to carry out, for example, axial and radial machining operations on turned parts. This object is achieved in that the tool holder drives a tool by a cooling medium under pressure. Thus, eccentric bores, internal and external polygons, positive and negative grooves, threads, etc, can be made, for example, on turned parts. Axial and radial movements can thus be carried out in a superimposed manner by this solution.

Title: Method and appliance for intimate mixing of liquids with gases
Inventor: STAHL HANS DR
IPC: B01F5/00
Filed: 1987-12-10
Abstract: It is known that, for intimate mixing of liquids with gases, in particular of a flotation pulp which is fed to a flotation cell, the liquid is passed through a duct under pressure and at the same time admixed with gas. Intimate mixing and uniform dispersion of gas in a liquid, particularly in the case of admixing gas to a flotation pulp containing very fine coal or ore particles (below 20  mu m) often presents major problems, in order to cause it to adhere to said fine granular solid particles and cause them to float up. Mixing of alkalis with gases may likewise, owing to the sometimes quite high viscosity of the liquids to be treated, present difficulties and be uneconomical. According to the invention, however, intimate mixing of liquids having variable consistency with gases, especially of a flotation pulp which is fed to a flotation cell, is achieved in a simple manner by the liquid being passed through a duct (1) having annular discs (7) which are arranged at relatively large spacings and project inwards, a displacement body (8) running axially being arranged inside the annular discs (7), which body deflects the liquid in a meander-like manner. <IMAGE>

Patent DE-3810829-A1 (DE)
Inventor: SCHULZ ALFRED DIPL ING
IPC: F02D41/14
Filed: 1988-03-30
Abstract: In a process for pilot control and regulation of the lambda value of an air/fuel mixture to be supplied to an internal combustion engine, a delay time is determined in function of the values of the operating barometers corresponding to the actual operating condition. The delay time is essentially equal to the time-interval between the change in an operating parameter and the moment at which the exhaust gas produced by the air/fuel mixture formed at the moment at which the change occurs in function of a new value of pilot control parameters reaches the lambda probe, the new value of the pilot control parameters having been determined at the moment of the change in function of new values of the operating parameters. The comparison between the target and actual lambda values is retarded by the delay time. As a result of this delay, errors of regulation due to the fuel flow times are then limited solely to the deviations between the actual and target lambda values. Devices which operate on this principle are therefore less prone to hunting.
