Title: Method and device for obtaining milk samples from a flow conduit
Inventor: MIETH HANS OTTO DIPL ING
IPC: G01N1/20
Filed: 1988-11-05
Abstract: The invention relates to a method and a device for obtaining milk samples from a flow conduit leading from a first to a second container, in which, in each case during the transfer of a volume of milk to be tested, a volume representative of the transferred total volume is diverted out of the flow conduit, collected, and a partial volume as a sample is removed from the collected volume at the end of the transfer. By means of a method of this type and a device for carrying it out, it is ensured, inter alia, that the partial stream removal can be carried out at any arbitrary place from the flow conduit and, in all phases of the transfer of the milk volume to be tested, the diversion of a representative volume is provided. According to the proposed method, this is achieved, inter alia, by removing the diverted volume from the flow conduit continuously in a quantity dependent on the backpressure in a way known per se, by aligning the static pressure in the diverted volume without delay to the static pressure on and over the liquid in the vicinity of the point of removal, and specifically without the transport of liquid caused by a pressure equalisation into or out of the diverted volume. A device for carrying out the method provides for this purpose, inter alia, that a pressure equalising conduit (6) opens into the head-space of a container (17), and that a dip tube (17b) is provided, which [lacuna] in ...

Title: Level control device for vehicles with a pneumatic spring system
Inventor: SCHOENFELD KARL-HEINRICH DR IN
IPC: B60G17/052
Filed: 1989-01-17
Abstract: In known level control devices, the pneumatic springs of each side of the one axle and the pneumatic springs of the other axle together can be connected to the pressure medium source or to the atmosphere. As a result, it is possible to execute even level movements which virtually only occur when a vehicle-symmetrical load distribution occurs. The new level control device is intended to permit all customary level changes which occur during practical operation to be compensated with a lower degree of outlay. The valve device (6, 8, 9) has two-way valves (8) and (9). By means of the directional control valve (8), on the one hand, an inlet (10) of one pneumatic spring subsystem (2, 3) and on the other hand an inlet (11) of the other pneumatic spring subsystem (4, 5) can be connected to a pressure medium source (1) or to the outlet to the atmosphere (7). By means of the directional control valve (9), it is possible to connect on the one hand the pneumatic spring (4) of the one side of the vehicle and on the hand the pneumatic spring (5) of the other side of the vehicle of the other pneumatic spring subsystem (4, 5) to its inlet (11). The level control device is suitable for all vehicles with pneumatic springs. <IMAGE>
Patent DE-3903765-A1 (DE)
Title: Quick-clamping device for disc-shaped working tools of electric tools
Inventor: EISENHARDT ARMIN DIPL ING
IPC: B24B45/00
Filed: 1989-02-09
Abstract: In the case of known quick-clamping devices for the said purpose, the clamping flange bearing on the working tool is relieved of the clamping force for the tool by the fact that supporting means designed as rolling bodies are movable, as desired, into an alternative space. The new quick-clamping device is to make possible a lower overall height while avoiding rolling supporting means movable into an alternative space. The loading and relieving of the clamping flange (14) with and of the clamping force for the working tool is effected with the aid of corresponding entrenchments (17, 18) provided on the clamping nut (10) and on the clamping flange (14). These entrenchments are prevented from a movement relative to one another in the clamped state of the working tool by blocking elements designed as toggle joints (11). By turning the adjusting ring (13), the toggle joints (11) collapse, so that a relative movement between clamping flange (14) and clamping nut (10) is possible and occurs under the effect of the axial force. <IMAGE>

Title: Device for determining the E-modulus (modulus of elasticity)
Inventor: EHRLER CHRISTOF
IPC: G01N3/34
Filed: 1989-02-10
Abstract: The invention relates to a device for determining the E-modulus of earth materials and constructional materials, such as especially road-making materials. The object according to the invention is achieved in that a spring element and, above this, a falling weight of adjustable mass and height are arranged on the base plate. The usefulness consists mainly in that it is possible with such a device to reduce the pulse of the oscillation excitation to the amount just necessary and, together with the preferred matching of mass and height of the falling weight and the loading mass of the base plate to an approximately constant ratio of static and dynamic stress in the sole surface, to reduce the influence of the dynamic impulse transmission to the "static" measured value and, at the same time, to keep it constantly small. On the other hand, a plurality of impulses of the falling weight, which is bounced back upwards by the spring and strikes again, enter into the determination of the average oscillation period of the oscillations of the system which can be evaluated, that is to say which can be raised relative to the noise level, the said impulses always re-stimulating the oscillations so long as the recoil height is sufficient. The impulses, reducing in this case, have a favourable effect on the accuracy of the measuring result, via the average value formation.
