Title: Linear actuator driven by an electric motor with a fixed end position.
Inventor: TIEMANN HEINRICH
IPC: F16H25/20
Filed: 1983-08-03
Abstract: When closing a final control element by means of a linear actuator driven by an electric motor with a fixed end position, excessive forces occur due to rotating masses of the motor, due to surges (within the permissible tolerance range) in the supply voltage or due to varying degrees of efficiency of the gearing. To limit the maximum actuating force acting on the final control element, the driving sleeve for the spindle nut of the linear actuator is held resiliently in the housing of the linear actuator by way of cup springs, such that it can be displaced in the axial direction, the screw bears an adjustable stop nut and the driving sleeve for the spindle nut is provided with a sprung stop bearing for the stop nut. The cup springs and the sprung stop bearing, together with the adjustable stop nut, limit the actuating force of the linear actuator acting on the final control element. A method for setting the desired maximum actuating force is specified.

Title: Electronically operated valve device for mixing fluids
Inventor: KIENDL HARRO PROF DR RER NAT
IPC: G05D23/13
Filed: 1984-03-02
Abstract: In an electronically driven mixing valve for mixing two fluids (e.g. water) for preparing a mixed fluid (e.g. mixed water) having a preselected value of a parameter (e.g. temperature) of the mixed fluid, it being possible for this parameter to be calculated algebraically in the same way from the corresponding parameter values of the feed fluids taking account of the mass flows, as in the case when the parameter of interest is the temperature, it is proposed for the purpose of reducing the mixing errors to connect upstream of the electronically driven mixing valve a disturbance variable compensator for compensating fluctuations in the values of the parameter of interest (e.g. the temperature) of the feed fluids and fluctuations in the pressure ratio PK:PW of the feed fluids, it being the case that apart from the values of the parameter of interest (e.g. the feed temperatures) the disturbance variable compensator is fed not the value of the pressure ratio of the feed fluids, which is difficult to establish using measurement techniques, but instead of this the value q of the position of the relevant shut-off part of the mechanical valve and the value of the parameter of interest of the mixed fluid (e.g. the mixing temperature).

Patent DE-3440347-A1 (DE)
Title: Mast-foot slide
Inventor: FACKLER THOMAS
IPC: B63B35/79
Filed: 1984-11-05
Abstract: This mast-foot slide serves to infinitely adjust the mast position of a surfboard. This is achieved through the use of a worm drive. The power joint, which transmits the rotary movement of a rope revolving in front of the mast to the mast-foot slide, is inserted into the worm from above. The worm wheel rolls over the guide rail, designed as a toothed rack, of the mast-foot slide. If the surfer pulls the rope, the worm rotates. The worm wheel driven by the worm now rolls along over the guide rail and thus moves along the entire mast-foot slide. The self-locking action of the worm drive ensures that the mast-foot slide cannot be moved along by pressing on it.

Patent DE-3513068-A1 (DE)
Title: Mobile undercarriage with castors
IPC: B60B33/02
Filed: 1985-04-12
Abstract: The mobile undercarriage has castors having a vertical rear trunnion and in particular is an undercarriage for a hospital bed or a trolley. The invention has the object of making such mobile undercarriages capable of fault-free automatic running over relatively long transporting distances, in particular of making hospital bed undercarriages suitable for fault-free running through automatic cleaning or disinfecting lines. The invention achieves this object by a particular design of the mobile undercarriage 1 and its castors 3, which permits fault-free automatic transporting by a "piggy-back method", in which the undercarriage 1, equipped with castors 3, is thus transported at times on the back of an automatically advanced subframe 4 or the like. For this purpose, the castors 3 are held by their rear trunnion on the undercarriage feet 2 so as to be vertically movable through some millimetres and possess a swivel inhibitor 6, which comes into engagement by means of a small vertical lowering "S" of the castor 3 when the automatically advanced undercarriage 1 is lifted out of the guiding or conducting rails 5 and, in the process, locks the castor 3 in the transporting direction, with the result that its running wheel 16 afterwards once again enters into the guiding or conducting rail 5 pointing in the correct direction. <IMAGE>

Title: Method and device for testing cigarettes
Inventor: HEITMANN UWE
IPC: G01M3/26
Filed: 1985-05-11
Abstract: A method and a device for testing the covering of rod-like articles (3) of the tobacco processing industry are described, in which a differential pressure between an inside space of the articles enclosed by the covering and a space outside the covering is generated by the application of a pneumatic test pressure. Changes in pressure due to leaks in the covering are detected so that measuring signals can be formed. The pressure of an inlet pressure volume (17), which generates the test pressure needed for testing of the cigarettes, is measured as inlet pressure. An evaluation arrangement (51, 53) forms the ratio from test pressure signals acquired by conducting measurements on the cigarettes (3) and from inlet pressure signals acquired by measuring the inlet pressure, and generates test signals in accordance with this ratio. <IMAGE>
