Abstract: Known systems which are made up of stereometric building blocks and are defined without separate coupling are usually multi-structural (for example the "stud/hole connections") and often permit only vertical extensions. In addition, the profiled surface regions are often disadvantageous from an aesthetic point of view. The aim of the invention is constituted by stereometric building blocks without separate coupling, having:     1. mono-structural and enclosing coupling profile 2. invariant congruence of the profile with respect to 90 DEG -turns     3. horisontal extensions with cyclic interlinking in certain cases   4. finger-push coupling   5. centring of the coupling guide   6. latching attachment   7. low material outlay   8. aesthetically pleasing surfaces.   Requirement 1. gives rise to the problem 9. of the sealed attachment of structural elements on concave-orthogonal surfaces and of the sealed insertion of structural elements into concave-orthogonal interspaces of the same sise. Requirements 1. and 3. give rise to the problem 10. of orthogonal countersinking of the local depth profiles into the overall surface profile of the mating building blocks at the potential extensions. The building-block system represented here takes as departure point a "self-complementary coupling profile" which fulfils the abovementioned properties 1-8.

Title: Method and device for driving a motor at a variable rotation speed
Inventor: KESSLER HERMANN GERHART
IPC: H02M1/084
Filed: 1993-06-12
Abstract: A method is described for driving an asynchronous motor (4) at a variable rotation speed, in the case of which method a control electronics device (2; 102) of a frequency converter (1; 100) produces a number N of control pulses (S0-S15; S0-S31), which are in each case separated by one clock interval, in order to vary or regulate the rotation speed of the asynchronous motor (4). These control pulses are fed to a power section (3), which supplies the asynchronous motor (4), of the frequency converter (1; 100) which emits an output signal at the frequency fs, the mean value of which output signal is essentially sinusoidal [sic]. According to the invention, it is in this case provided that the pulse width of each control pulse (S0-S15; S0-S31) is defined independently of the rotation speed of the asynchronous motor (4) which is to be varied or regulated, and that the time duration of each clock interval which separates two control pulses (S0-S15; S0-S31) which follow one another in time is varied as a function of the rotation speed, in such a manner that the power section (3; 103) of the frequency converter (1) emits an output signal at the frequency fs, the mean value of which output signal is essentially sinusoidal. <IMAGE>

Title: Drive of a storage and retrieval unit for tall storage racking
Inventor: SORG HANSPETER
IPC: B66C9/14
Filed: 1994-03-10
Abstract: The subject matter of the invention is the further development of the wheel and running mechanism with the aim of using a friction-wheel drive of uncomplicated design in order to obtain increased acceleration of the unit on the floor rail (1) even during considerable loading of a storage and retrieval unit. The essence of the invention consists in the fact that the load carrying and acceleration are uncoupled. The mass of the storage and retrieval unit is carried by one or more load wheels (2) which run on the top flange (1a) of an H-girder. A friction wheel (3) or advantageously a pair of friction wheels, driven in opposite directions and acting on both sides on the web (1c) of the floor rail (1), transmits the drive torque from the motor (5) via gearing (4) to the wheel and running mechanism. A swivelling bolster is especially convenient for setting and adjusting the pressure force of the friction wheels (3) on the web (1c). <IMAGE>
