IPC: G01N21/956
Filed: 1993-05-10
Abstract: A method is described for testing the uniformity of continuously moving or stationary surface structures with periodic ordering, in particular for all types of textile materials such as lattice work, filter fabrics and other wire meshes etc. Known methods are only partly suitable for assessment of uniformity and are limited to thread-like structures. In order to carry out the method, use is made of a transmitted light measuring arrangement with slit optics or a slit diaphragm between the light source and the detector, the intensity of the light beam being measured and the spectral density being determined as a function of wavelength by spectral analysis. The spectra obtained are evaluated as a measure of the uniformity. <IMAGE>

Title: Dialogue-oriented programming device and method for generating control programs for CNC machines
Inventor: MONZ JOACHIM DIPL ING
IPC: G05B19/4093
Filed: 1993-09-07
Abstract: The invention relates to a dialogue-oriented programming device and to a method for compiling control programs for CNC machines having screen and keyboard to enter and to change the desired functional sequence and control sequence of the machine. In a central storage unit and processing unit, the input data are processed to form control data for the machine control and are output as a control program for the machine. In order to configure such a programming device to be flexible and more configurable for the user or programmer, it is proposed to arrange, in the central storage unit and processing unit, a dialogue macro interpreter for describing the processing sequence and dialogue sequence (functional description unit), the sequence description and the allocation and assignment of program parameters to the desired functions of the machine being input to this unit in the form of a functional control matrix, together with the sequence description. The data thus prepared are fed to a program editor unit (functional control unit), in which the data prepared in the dialogue macro interpreter unit are connected to current parameters and further applications and are processed to form program running times (run-time programs). From these, a dialogue-oriented machine control program is then compiled.

Title: Sterilisation, pre-drying, and drying of raw cocoa beans and cocoa nibs
Inventor: SCHMID HELMUT
IPC: A23G1/02
Filed: 1993-12-03
Abstract: To sterilise and dry green (raw) cocoa beans, or cocoa nibs (split kernels), pref. in a single vessel (1), firstly live steam to sterilise, and then hot air to dry, is blown in. The vessel is also heated, by a steam jacket (2), assisting the drying process.  Pref. the steam used has a pressure of about 2.5 bar and a temp. of 138 deg C. To pre-dry, immediately following this steam-sterilisation, the vessel and contents are also subjected to evacuation for a short time; about 1 min. suffices. A water ring pump pulls an adequate vacuum for this stage. Hot air drying then achieves the required moisture level. All this precedes the stages in which the contents are crushed and air-classified to remove the shells. Air for drying is induced through an inlet filter (18), is heated in an indirect heater (16) to 140-150 deg C before passing to the dryer (1). This air is circulated through the content to reduce their moisture to the desired residual level, which is determined from the wt. change in the prod., as measured by a vessel weighting system (3). Recirculated drying air is passed through a condenser (26), where it is partially dried.
