Title: Proportioning weigher
Inventor: TREIBEL KLAUS
IPC: G01G13/24
Filed: 1988-03-07
Abstract: The invention relates to a proportioning weigher having a weighing pan (scale pan) (2) and a weight measuring device (1) which determines the weight of a material on the weighing pan (2). A pump (6) pumps a liquid out of a liquid container (7) via a discharge nozzle 10 into a container on the weighing pan (2). Connected downstream of the pump (6) is a flow meter (5) which generates a first signal S1 when liquid flows through it. By means of an input device (15), it is possible to input a percent value which designates the quantity of liquid to be added via the discharge nozzle (10) to achieve a desired material-to-liquid ratio of the material (4). The measurement is subdivided into a coarse and a fine measurement. During coarse measurement, a pure volume measurement takes place which is stopped at a specific value before reaching the desired value. By means of a monitoring measurement and calculation of a correction value from the difference between the calculated desired value and the actual weight of the material 4 and the quantity of liquid already added, a possible error is minimised during the subsequent fine measurement. <IMAGE>

Title: Process and apparatus for the selective removal of at least one constituent from the gas mixture
Inventor: FRAHNE DIETRICH PROF DR
IPC: B01D53/26
Filed: 1988-06-03
Abstract: The invention relates to a process and an apparatus for the selective removal of at least one constituent from a gas mixture, in particular for drying a gas with a membrane (5) permeable to polar molecules and serving as a partition. A process and a corresponding apparatus are already known in which, to separate gases by the permeation principle, a membrane permeable to polar components is used as partition. The membrane in the previously known process is flushed with air or, if required, with another gas, on the side facing away from the gas or gas mixture to be treated. However, with the previously known process, only highly unpolar constituents of the gas to be treated can be retained. In contrast, in the process according to the invention and the corresponding apparatus, the membrane (5), on the side facing away from the gas or gas mixture, is bathed by a flushing liquid which has a preferential affinity for the constituent to be selected. Surprisingly, by the choice of certain flushing liquids, selections can be achieved specifically without significant losses of other components. A particularly advantageous design of the invention is that the apparatus has a plurality of permeation modules connected together which are arranged one after the other in the flow direction of the gas or gas mixture. It is particularly advantageous if the ... Original abstract incomplete. <IMAGE>

Title: Method for generating modulated single-sideband signals
Inventor: HUNECKE ERNST DIPL ING
IPC: H03C1/60
Filed: 1988-09-09
Abstract: The invention relates to a method for generating a single sideband signal by forming amplitude and phase values according to mathematical rules. The AF signal to be modulated is first split into its I and Q components according to the Hilbert transformation and the phase  phi T(t) is formed from the carrier signal. The desired single sideband signal is then formed from the root value of the squared and added I and Q components multiplied by the sine of carrier phase  phi T(t) plus/minus the associated AF phase.
Patent DE-3836327-A1 (DE)
Inventor: GRIESEMER ALBERT
IPC: B60R22/20
Filed: 1988-10-25
Abstract: The device consists basically of a guide rail, an adjustment component and a spring component. According to the invention, a leaf spring 3 is to be inserted as spring component, said leaf spring extending essentially over the length and width of the adjustment component 2 and being connected to the adjustment component 2 to form a construction unit clamped onto the guide rail 1. In this arrangement, the leaf spring 3 is not only significant for locking purposes but also generally for retaining and guiding the adjustment component 2. It thus assumes a further function and permits a particularly simple shaping of the adjustment component 2 so that manufacture and assembly of the device are more convenient overall. For the connection of the leaf spring 3 to the adjustment component 2, projections 7 in the adjustment component 2 are expedient. Furthermore, the displacement is facilitated by guide noses 22 on the adjustment component 2.
