Patent DE-3726352-A1 (DE)
Title: Method and arrangement for the automatic determination of the particle size distribution of coarse single-component material systems
Inventor: HOFFMANN JOERG DIPL ING
IPC: G01N15/04
Filed: 1987-08-07
Abstract: The invention relates to the field of particle measurement technology. Possible fields of application of the invention are quality determination or quality control and laboratory investigations of products particularly in the building industry and the chemical industry. Particle sizes which have hitherto been almost exclusively determined by sieve analysis can be measured more quickly, more accurately and in substantially more finely stacked continuously variable classes. The computer-supported measuring facility immediately gives the result in the form of plotted curves of the particle size distribution, mass distribution etc. The principle of the invention is based on the masking of a representative section of sedimenting particles without disturbing the sedimentation of these particles themselves, with use of a pure run-time measurement (covering method), the optoelectronic cyclic counting of these particles and also a pre-processing facility which is characterised, in particular, by coincidence recognition. <IMAGE>

Patent DE-3735362-A1 (DE)
Inventor: BUERKLIN WERNER
IPC: C05F9/02
Filed: 1987-10-19
Abstract: A method for composting waste or refuse, in particular coarse refuse, such as bushes or the like, in which the waste is comminuted and transferred to a storage site, is to be improved in that the comminution of the waste takes place during its collection into the transport vehicle (10), and the comminuted refuse is directly passed by the said vehicle to a dumping gang (70). In addition, the comminuted refuse is to be conveyed to an impact chamber (86) which is enclosed all round, open at the bottom and projects upwards from the storage location - preferably by centrifugal force - and distributed therein to form a composting layer, after which the chamber is lifted by the height of the composting layer (M1) and additional building up takes place on the surface thereof to produce a further layer.

Title: Soil-loosening appliance
Inventor: RITTER GEORG DIPL ING
IPC: A01B1/06
Filed: 1988-05-19
Abstract: The soil-loosening appliance according to the invention brings about an outstanding loosening, tilling and intermixing of preferably upper layers of topsoil 19 with only little expenditure of force and time.

Inventor: CARDANO ROBERTO
IPC: H03K17/082
Filed: 1989-09-27
Abstract: The device includes at least one power transistor 15 whose collector-emitter path is in series with the motor of an electric fan, between the two poles of a direct-voltage supply 7. A drive circuit 14 receives a variable control signal Vc in dependence on which it varies the collector-emmitter voltage of the transistor 15. A negative feedback circuit 16 is connected to the collector of the transistor for closed-loop regulation of the motor speed. A threshold circuit 18 cuts off the drive circuit 14 when the signal provided by a temperature sensor 17 indicates that the temperature of the transistor 15 exceeds a predetermined value. The signal provided by the temperature sensor 17 is also available at an output terminal 12 of the device to enable external processing. When the control signal Vc exceeds a given level, circuitry 19-21 bypasses the transistor 15 to increase the motor speed. The device may be part of a vehicle air-conditioning system. <IMAGE>
