Patent DE-3043732-A1 (DE)
Title: Tilt control for tailgate hoist - has ground sensing switch and tilt sensing switch connected in alternate layout
Inventor: WIELOCH DIETER
IPC: B60P1/44
Filed: 1980-11-20
Abstract: The ground sensing control is located in the linkage which lifts the platform hoist and operates when the linkage has dropped the platform sufficiently. An attitude sensor on the platform provides a feedback control and both switches are interlocked into a safety circuit which ensures the correct operating sequence at all times, i.e. the platform is not tilted during lifting/lowering. The ground sensing control operates independently of ground contact so that the platform is correctly tilted even when a conventional sensing switch is ineffective due to holes in the ground. The interlocked control ensures that the load cannot slip off due to inadvertent tilting.

Title: Method for utilising the reaction enthalpy of exothermal heterogeneously catalysed gas reactions
Inventor: SCHOENEMANN KARL PROF DR PHIL
IPC: F01K25/14
Filed: 1981-03-12
Abstract: In the case of exothermal, heterogeneously catalysed gas reactions, the temperature, and thus for a given reaction volume the pressure, of the reaction mixture increases. Said pressure is directly converted, via a pressure gradient and by means of a heat engine, e.g. a turbine or a piston machine, into mechanical drive energy. By utilising the reaction enthalpy in this manner, the reaction temperature is maintained in the range of the suitable reaction rate. The compression of the gas mixture required for reactions at elevated pressure is achieved by means of a compressor which is driven by the utilised reaction enthalpy. Expediently, reaction turbine and compressor are arranged on a common shaft. Example ammonia synthesis.

Title: Apparatus for electrochemical measurements, particularly pH measurements, having a device for cleaning the measuring electrode and/or recalibrating a measuring cell
Inventor: GALSTER HELMUTH DR
IPC: G01N27/38
Filed: 1981-05-12
Abstract: The invention relates to a sensor for electrochemical measurements, in particular pH measurements, having automatic cleaning and calibration of the measuring cell. In order to minimise the consumption of cleaning agent and calibration solutions, the measuring cell is installed in such a way that it is immersed in a small recess which promotes flow and which serves as cleaning and calibrating vessel after the test solution has been drained. The cleaning agent and calibration solutions are fed into the recess so as to displace the residue of the test solution in accordance with an individually specified program. As a preparation for cleaning and calibration, the test solution is drained from a flow sensor after the circulation has switched off automatically. In an immersion sensor, this is effected by compressed air in conjunction with a downcomer tube, so that the automatic cleaning and calibration can also be applied to this type of sensor.

Title: Method and apparatus for drawing off the thread from thread feed bobbins, especially from conical sewing-thread bobbins
IPC: B65H59/06
Filed: 1981-05-27
Abstract: In sewing or suchlike thread-processing machines (1), the thread feed bobbins (12) provided with a hollow bobbin tube (13) are slipped onto bearing plates (3) arranged fixedly relative to the machine, the drawing off of the thread (14) taking place from the outer circumference of the thread feed bobbins. In order to avoid a thread balloon forming, the thread (14) running off on the outside from the stationary bobbin (12) is drawn off first over the top edge (13'') of the bobbin tube (13) through the cavity (13''') of the latter, then radially outwards between the bobbin tube (13) and the bearing plate (3) located underneath it, and finally in a manner deflecting it upwards. During its passage of the bearing plate (3), the thread (14) to be drawn off is at the same prepared. In order further to improve the thread run-off, there is slipped onto the lower end of the bobbin tube (13) a foot disc (9) which possesses a thread run-off edge projecting radially beyond the circumference of the winding-thread package (12) located above it and which is to be placed flat onto the bearing plate (3). <IMAGE>

Filed: 1981-07-20
Abstract: A description is given of a lens assembly having a single operating element which is set up such that it can be operated to carry out both the focusing process and the zoom process. Furthermore, a rotation-inhibiting device is provided which prevents rotation of the single operating element during its axial displacement for the purpose of carrying out the zoom process, in order to avoid the preset range from being varied. The rotation-inhibiting device has a mechanism which builds up a friction or spring force between the single operating element and a mounting element of the lens assembly, in order to prevent relative rotation between these two during the zoom process. The rotating force is built up by a retaining element of the lens assembly which can be operated by hand.
Patent DE-3134804-A1 (DE)
Title: Steam-release and relief valve
Inventor: SAMADELLI RENATO
IPC: F16K24/00
Filed: 1981-09-02
Abstract: The steam-release and relief valve has an axially movable valve element (27) which is mounted in a valve housing (4) and is pressed onto an annular valve seat (11) of the valve housing (4) by a spring (29). To open the valve, the valve element (27) is raised from the valve seat (11), counter to the pressure of the spring (29), by means of a rotary handle (18) or by an excess pressure in the pressure vessel. The valve element (27) has a coaxial cylindrical hole (31) which is open towards the interior (3) of the pressure vessel and, at its other end, opens via a through opening (32) into a steam release channel (16) connected to a steam release branch (14). A ball (37) retained by a ring (38) is arranged in the hole (31) with the ability to move freely in the axial direction. When the pressure vessel is put into operation with the lid and the valve closed, the air in the pressure vessel can initially escape via the hole (31), the through opening (32) and the steam release channel (16) into the open due to the steam pressure which builds up when heated. When the steam pressure rises, the ball (37) is pressed against the through opening (32) counter to the force of gravity, thus closing this passage. It is thereby possible to achieve automatic venting of the interior of the pressure vessel before the actual boiling process. <IMAGE>

Patent DE-3147771-A1 (DE)
Title: Valve for controlling and regulating the volume flow or the pressure of a preferably hydraulic medium
Inventor: WITT PETER
IPC: F15B13/044
Filed: 1981-11-30
Abstract: A valve for controlling and regulating the volume flow or the pressure of a preferably hydraulic medium has an actuator with at least two different effective positions which are in each case allocated to a specific volume flow or to a specific pressure value. By operating an operating element which is preferably constructed as an electromagnet, the actuator can be changed over from one effective position to another effective position, so that, using the valve, an accurately repeatable changeover is possible between, for example, two volume flow rates or pressure values. The limit positions of the lifting movement are both adjustable so that both effective positions can be set. This can be done by the entire operating element (electromagnet) being adjusted with respect to the valve body in order to set one limit position, while the other limit position can be set by adjusting the return movement. The valve can replace two flow control valves and one switching valve.
