Title: Method for processing the fluidised-bed ash discharged with the flue gases or arising in the filters
Inventor: ACKERMANN MANFRED DIPL ING
IPC: C04B18/02
Filed: 1987-06-01
Abstract: Fluidised-bed ash which arises, in particular, in the combustion of washed dirt (rejects) and is conducted away together with the combustion gases and retained in the filter, can be fed to an economic utilization by mixing it with a portion of cement below 15% and then adding it to a porous material in coarse pieces of low bulk density, previously moistened to saturation. The product of fluidised-bed ash, up to 70% arising below 63 mu , and cement aggregates in this case to form a water-saturated core material in relatively coarse pieces, forms a solid coat around this and leads to a specific volume enlargement, so that such a material can then be discharged from the mixer, hardened, stored and finally used as a low-density aggregate. As a low-density aggregate, this mixed product can be used after hardening, for example, as a substitution product for natural pumice in the manufacture of expanded concrete, building blocks or hollow building blocks. <IMAGE>

Title: Drive circuit for a bass loudspeaker
Inventor: KOKES MICHAEL DIPL ING
IPC: H04R3/04
Filed: 1987-06-01
Abstract: A drive circuit for a bass loudspeaker, particularly an electronically controlled bass loudspeaker, is proposed by means of which the lower cut-off frequency is changed as a function of the excursion of the loudspeaker. This means that with a high volume, the lower cut-off frequency of the loudspeaker is raised or, conversely, at low volume, the lower cut-off frequency is lowered. This is achieved by means of a number of first-order high-pass filters. This provides the possibility of optimally utilising the loudspeaker and of modulating it independently of the drive frequency up to the maximum excursion of the loudspeaker diaphragm.

Title: Keyboard for entering commands
Inventor: GROZ PETER
IPC: G06F3/023
Filed: 1987-07-10
Abstract: When commands are entered via a keyboard into a programmable device, e.g. a home computer, CD player or washing machine, the operator, who generally has no special programming skills, is forced to acquire the necessary knowledge, with difficulty, from the operating instructions. To make correct entry of commands easier for the operator, and to prevent wrong operation as much as possible, the permitted or not permitted command keys, depending on the program sequence in the control or arithmetic unit, are identified optically in each case, according to the program sequence. This can be done, for instance, by illuminating the currently permitted command keys. The keyboard is suitable for all devices and systems with a keyboard for entering commands, e.g. computers, CD players, video recorders, industrial plants, power stations, etc. <IMAGE>

Patent DE-3818591-A1 (DE)
Title: Process for the production of reduced cholesterol fat products with simultaneous removal of contaminating substances with the possibility of obtaining cholesterol
Inventor: HERRMANN MARTIN PROF DR ING
IPC: A23C15/06
Filed: 1988-06-01
Abstract: Attempts to reduce the cholesterol in butter oil have shown that reduction rates of 20% can be achieved relatively easily. With a cholesterol reduction of 88%, adsorption on silica gel, this process was particularly noteworthy. The possibilities of reducing cholesterol by washing out with monoglyceride-containing water, which gave reduction rates up to 22.1%, can likewise be further optimised. In this case, the number of possible solubilisers is far higher than that taken into account in attempts to date. It has furthermore emerged that contaminating classes of substances can be removed simultaneously with the cholesterol from fats and from fat-containing substances preferably by suitable adsorbents such as, for example, silica gel, active carbon or aluminium oxide. The cholesterol present in the adsorbent can be recovered by a polar solvent. This can be removed by distillation to isolate the cholesterol.

Filed: 1988-06-18
Abstract: A viscosity measuring device has a pair of externally toothed disks A, B arranged alongside one another, but secured one in relation to each of the two ends of a driving shaft the viscosity related torque on which is to be measured as a drum mounted thereon rotates in the liquid whose viscosity is to be measured, changes in the viscosity giving rise to changes in the torque which give rise to changes in relative angular displacement of the disks which are detected optically using a light beam transmitted through the toothed disks. According to the invention, the circumferential width of the teeth 120 of one of these two disks is smaller than the opening existing between the adjacent teeth 110 of the other disk and at all torque values each smaller tooth 120 lies in register somewhere within its associated opening, so that for measurement purposes the displacement D between like edges of the optical signal C corresponding to the respective teeth 110, 120 (e.g. the respective leading edges) can be measured. <IMAGE>

Title: Antilock control system for motor vehicle brake systems
Inventor: SCHULZE BERND GUIDO DIPL ING
IPC: B60T8/58
Filed: 1988-12-10
Abstract: In known antilock control systems the wheel slip is generally used as control variable or as auxiliary variable. In order to determine the wheel slip it is necessary to know the speed of travel which must be measured extremely accurately with an error of < 1%. The new antilock control system is accordingly intended to manage with low-cost measuring methods but nevertheless to provide a usual quality of antilock control. For this purpose, the control electronics perform a rotational speed control for any braked vehicle wheel on which a risk of locking is detected, a reference variable, which corresponds to the rotational speed of a braked vehicle wheel rotating with a predetermined slip, initially being preset as rotational speed set value, and the reference variable thereafter being continuously varied until the speed control circuit attains its stability limit. <IMAGE>

Title: Cable drum
Inventor: KROSCH JOHANN DIPL ING
IPC: B65H75/18
Filed: 1988-12-15
Abstract: Cable drums consist of the drum body and side walls attached radially thereto, said side walls produced from dual-layer boards having a covering outer ring at the outer edges. Said outer ring must be joined together when it has been fitted onto the outer edge of the side walls, which is possible largely independent of tolerances due to the fact that the U-shaped outer ring comprises a U-shaped fitting piece in the end region of the ring. Said fitting piece and the outer ring are fixed together on the side walls or their outer edges, specifically on the one hand by a circumferential attachment bead and, on the other hand, by the connection between the outer ring and the fitting piece, preferably by end-point welds or corresponding bead construction. Considerable advantages in terms of production and assembly are achieved by the prefabrication of the outer rings which is largely independent of tolerances. <IMAGE>
