For this purpose, the different density of the air/dam material mixture in a section of the conveyor duct through which a light source can be passed transmits optical signals to a photocell which are converted into electrical current and control, in an amplified manner via a control valve, the addition of water in proportion to the density. <IMAGE>
Patent DE-3233293-A1 (DE)
Title: Method for controlling pulse-controlled invertors
Inventor: GEKELER MANFRED W DIPL ING
IPC: H02M7/48
Filed: 1982-09-08
Abstract: The subject-matter of the invention is a method for controlling pulse-controlled invertors, especially those of a three-phase design and having a DC voltage circuit at a largely constant voltage, as are frequently used for supplying rotating field machines in variable-speed drives. It is based on space-vector representations for the desired and possible voltage systems and approximates a desired voltage space vector by a sequence of possible voltage space vectors. To this end, according to the invention, the desired voltage space vector is described by a magnitude signal and an angle signal. The latter is split into a sector identifying signal comprising 6 values and an angle identifying signal comprising 60 DEG . This is compared with an auxiliary angle signal whose time response is, inter alia, a function of the magnitude signal. This comparison is used to determine dwell durations to which in each case one of the possible voltage space vectors is then allocated, taking into account the sector identifying signal. The invention also relates to the generation of the auxiliary angle signal, the allocation of the voltage space vectors, the modification of various influencing variables and the type of (primarily digital) technical-circuitry implementation and use.

Title: Device for supplying high-speed railways with electrical energy
Inventor: HILLMANN WILLI ING GRAD
IPC: B60M1/34
Filed: 1982-09-25
Abstract: When supplying high-speed railways with rotary current, the problem of supplying power in a space-saving manner is experienced, for which problem contact line systems which are known from the power supply of suspended railways and the like are not readily suitable, especially since current rail-less areas have to be travelled through. For the reliable assignment of current collectors (for example 411/411'), associated (111) with the power unit, to the current rail system (31) or to the respective current rails (311, 312, 313), on the one hand a run-in funnel (36) is mounted ahead of the current rail system (31) and on the other hand the current collectors (for example 411/411') and swivel arms (411, 411') which form the components of the current collector can be rotated or swivelled with respect to the power unit about two axes which extend perpendicularly with respect to one another and contact elements (418) which form components of the current collectors are mounted so as to be rotatable or pivotable with respect to the current collector swivel arm (for example 411) about two axes which extend perpendicularly with respect to one another, in each case one axis of which extending perpendicularly with respect to the current rail system (31) and one axis extending transversely with respect thereto, furthermore, the pivot arm (for example 411) itself has limited elasticity. <IMAGE>

Title: Brake force regulator for a hydraulic vehicle brake system
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/74
Filed: 1982-10-14
Abstract: In a housing (10) an inlet chamber (12) and an outlet chamber (18) are formed for a first rear wheel brake circuit (HzI - RzI) together with an inlet chamber (58) and an outlet chamber (64) for a second rear wheel brake circuit (HzII - RzII). A deceleration-related valve (22, 24) with valve seat (22) fixed to the housing is arranged between inlet and outlet chamber (12, 18). The outlet chamber (18) is defined by a piston (46) which supports a spring (50). This spring (50) generates a return force acting on a slow-acting element (36), which force increases as the distance of the piston (46) from its stop (56) increases. The slow-acting element (36) is fixed to a pendulum (34) which controls the deceleration-related valve (22, 24). The vehicle deceleration at which this valve (22, 24) closes, thereby first reducing and then limiting the further rise in pressure in the associated rear wheel brake circuit (HzI - RzI), is greater the more heavily laden the vehicle. <IMAGE>

Title: Method and device for measuring the refractive index of liquids and gases
Inventor: MAECHLER MEINRAD
IPC: G01N21/45
Filed: 1982-12-03
Abstract: In order to measure the refractive index of liquids or gases, the substance is put between two light-transmitting plates which are arranged parallel to one another and whose spacing is varied in a defined fashion during the measurement. Reflection of light at the interfaces produces interference, and during the variation of the plate separation the number of the interference maxima and/or minima (orders) passing through is measured. Given a known variation in the plate separation, the refractive index can be determined therefrom. Illumination is done by white light in order to determine the spectral variation of the refractive index (dispersion), and the number of orders passing through is determined using a diode row spectrometer for numerous wavelengths.

IPC: A61J3/06
Filed: 1983-03-22
Abstract: A dragée drum (2) is provided with a stream distributor (3) which is connected to a fan (5) through a switching device (4). The drying air from a supply conduit (21) is introduced into a lower segmented channel (14) through the conduit (18), wherefrom it flows through the granulated bed (11) upwardly and is again introduced in the fan (5) through the upper segmented channel (15), the conduit (19) and the section conduit (22). This may take place in principle outside in a completely closed air circuit. Little before the polishing of the coating layer, the switching device (4) is switched so that the drying air may then flow from the top through the granulate bed towards the lower channel (14). The higher bearing pressure enables to obtain a better compaction, hardening and smoothing of the outer layers.

Title: Cleaning device, in particular for underground operations
IPC: B08B5/04
Filed: 1983-04-26
Abstract: The invention relates to a cleaning device, in particular for underground operations, having a partial vacuum generator to which a suction line is connected, and having a collection vessel which is connected into the suction line. Hitherto, said vessel was mounted on a movable frame together with the partial vacuum generator and, if appropriate, also with a filter. The collection vessel was open at the bottom so that the dirt could fall into an attached bag. This had to be emptied very frequently, which required the partial vacuum generator to be switched off. The difficulties associated with this can be eliminated according to the invention if the collection vessel is constructed as a portable device and provided with a closeable floor. The collection vessel can then be easily emptied by means of a mechanical transport means. The floor of the collection vessel can be formed by a flap which opens automatically when a predetermined weight load is reached.
