Patent DE-3126552-A1 (DE)
Inventor: KUPKA DIETER
IPC: G01N11/14
Filed: 1981-07-04
Abstract: The method allows an automatic control by means of an electronic data processing device (46) of all the parameters of a mixture process in a mixture container (10) provided with an agitator. The power absorbed is so adjusted as a function of the viscosity of the product to be mixed, measured continuously, that the mixing action is just kept up. The continuous measuring of the viscosity of the product is effected by a successive approximation based on measured values of the rotation torque of the agitator and of the number of revolutions of the agitator, as well as from the empiric relationship between the Reynolds number and the Nusselt number. To calculate the Reynolds number, a viscosity value based on experience is first taken; then, from the Nusselt number which is part of the calculated Reynolds number, the rotation torque value of the agitator corresponding to the estimated viscosity is calculated. Said value is compared with the effective rotation torque. If the two values of the rotation torque diverge, the estimated viscosity is corrected until the two values coincide.

Title: Covering, in particular roof covering
Inventor: STAEBLER KARL
IPC: E04D3/366
Filed: 1981-07-17
Abstract: The invention relates to a covering, in particular roof covering, which is made up of elements provided with longitudinally directed cavities and in the case of which said elements are provided, along the mutually facing sides, with connecting elements for pushing neighbouring elements one into the other in the longitudinal direction. In order to design the covering, with simple parts and simple mounting, in a self-supporting manner and such that it is possible to walk on it, the invention provides that the elements are designed as individual plastic tube portions, on the outer connecting lines of which the connecting elements are integrally formed, that the ends of the plastic tube portions are braced in clamping bearings which run parallel to one another and are at a spacing which is smaller than the length of the plastic tube portions, and that the inclinations of the clamping bearings are aligned with the curvature of the upwardly convexly arched plastic tube portions.

Title: Running roller, in particular castor, for apparatuses, furniture and the like
Inventor: SCHROEDER DIETER
IPC: B60B33/02
Filed: 1981-07-30
Abstract: The invention relates to a running roller for apparatuses, furniture and the like, in particular a castor, the wheel axle of which, which is mounted on the supporting part, bears a wheel essentially in the form of a shell at each end, with an operating lever mounted swivellably on the wheel axle and intended for adjusting a braking member which inhibits the rotation of the wheels and, in the braking position, makes contact with the insides of the shell wheels, the braking member, which is arranged such that it can move counter to the action of a restoring spring supported against the supporting part, pressing against the operating lever. In the roller according to German Offenlegungsschrift 3 030 772, the braking member, which is subjected to load by a helical compression spring, and the mating braking surfaces have closely stepped toothings which disadvantageously can easily be "levered out" when overcoming the braking torque. This is avoided according to the invention by virtue of the fact that at least one flat dog or recess (47) is arranged on the braking member (31) and a plurality of recesses or flat dogs (45) matched thereto is arranged on an inner circumferential surface (43) of the wheel (11; 12), the steep flanks (46, 48), which can be brought into engagement with one another, running essentially parallel to one another and also essentially in the direction of movement of the braking member (31). A further improvement of the braking member results from the fact that the braking member (31) is provided with a preferably integral elastically resilient tongue (38) which presses against the supporting part (10) counter to the action upon it of the operating lever (26). <IMAGE>

Patent DE-3222106-A1 (DE)
Title: Hydraulic control arrangement
Inventor: OLBRICH GOTTFRIED DIPL ING
IPC: F15B11/17
Filed: 1982-06-11
Abstract: A hydraulic control arrangement (10) with two pumps (15, 16) is proposed in which a first directional control valve (11) can control a combined flow of both pumps to a connected servomotor, the delivery flow of the second pump (16) being switched on smoothly. A restrictor (29), the pressure difference of which controls the operating valve (25) short-circuiting the second pump (16), lies in a neutral circulation passage (18) between a linking point (21) and the first directional control valve (11) as well as parallel to an inflow passage (33). A pressure relief valve (34) protects the neutral circulation passage (18) between the restrictor (29) and the first directional control valve (11). The pressure drop caused at the restrictor (29) by the neutral circulation short-circuits the second pump (16), by means of the operating valve (25), in the centre position (36) of all directional control valves (11 to 13). During lifting in working position (38), the neutral circulation is closed in a controlled manner, and the second pump (16) together with the first pump (15) delivers pressure medium to the first directional control valve (11). The pressure relief valve (34), together with the restrictor (29) and the operating valve (25), permits pressure separation in working position (38) when the servomotor travels against a stop. The differential pressure valve (39) permits parallel operation at a higher pressure level in the second directional control valve (12). <IMAGE>

Title: Method and device for transferring long stock, in particular elongated rolling stock
Inventor: ERP JUN MANFRED VAN
IPC: B66C19/00
Filed: 1982-08-06
Abstract: Transfer methods or devices of this type serve to feed and remove long stock (4), e.g. to and from the side-by-side arrangement of furnace grates (3) of annealing furnaces (1) in which the long stock (4) is deposited at distances (4a) apart and after the treatment is picked up again and deposited again on a roller discharge table (9) for further transport. In order to avoid the inaccurate positioning of the long material (4) by means of gripper devices, it is proposed that the long stock (4) first of all be lifted on the roller feed table (5) in each case into a predetermined position, that it then be picked up in such a way as to bear against a reference surface (11), formed in the transport direction, of the transport means which consists of supporting elements (12) with angular, roughly L-shaped arms (15, 16, 17) set down on the largest cross-section of the long stock (4), and transported perpendicularly to its longitudinal extent by a distance predetermined on the basis of the reference surface (11) and the respective cross-section (18) of the long stock, and that it then be delivered to the treatment station and/or to the roller discharge table (9). <IMAGE>

Title: Method for controlling the temperature and measuring the heat emission of radiators, and a device for carrying out the method
Inventor: BRODERSEN DAGMAR
IPC: G05D23/19
Filed: 1982-12-31
Abstract: A method and a device for controlling the flow temperature and the inlet valve of one of a plurality of radiators connected to one or more heat sources are described. The heating system has room temperature sensors and outdoor temperature sensors (46, 48). The special feature is that, on the one hand, the measurement sensors and control devices of one or more heat sources (12-28), hot water and industrial water reservoirs (32, 34), mixer valves (44) and outdoor temperature sensors (46, 68) are connected to a central control apparatus (10), while, on the other hand, the room temperature sensors and control devices of radiators are also connected to said central control apparatus (10). The connection of the latter takes place via the wiring (50) of the building. Using such a heating system, the heat emission to a room can be controlled in that the control signals of the room temperature sensor also influence the flow temperature and the control signals of the outdoor temperature sensor (46, 48) also influence the opening and closing movements of the radiator inlet valve. <IMAGE>
