Title: Plastics bottle code marking - using bottle movement for relative movement between bottle surface and divided laser beam bundle
Inventor: LEHMANN MARTIN
IPC: G06K1/12
Filed: 1991-08-29
Abstract: To apply a code marking to plastics bottles, using a divided laser beam bundle, the bottle is moved to give the relative movement between the bottle surface and the laser beam bundle. Pref., the code marking on the bottle, esp. of a PET material, can be read to assess the number of times it has been used and for a code to be applied to show that it has gone through another usage cycle. If the code shows that it has been used a number of times which would lead to the material becoming too brittle, then it is marked for removal at a later stage to be diverted to recycling by melting down into new bottles. ADVANTAGE - The code marking is applied easily and accurately, at a given part of the bottle surface

Title: Detection of partial discharges in enclosed HV switchgear - requires vibration sensor with signal frequency analysed and inspected for discharge patterns when voltage is above threshold
Inventor: HEUBERGER MICHAEL DIPL ING
IPC: H02B13/065
Filed: 1992-08-05
Abstract: In a procedure for detecting discharges within enclosed switchgear, a vibration sensor is used to monitor mechanical movement of components, the sensor signal being frequency analysed and then inspected for signs of a discharge having occurred. An indication is only given if the value of the voltage at the switchgear exceeds a certain threshold. Therefore the vibration sensor signal is only used when the voltage is above this threshold. Alternatively, the sensor is used continuously as input to the frequency analyser, but a blocking element only allows comparison of the result with known discharge patterns for voltages above the threshold. ADVANTAGE- High reliability; system only active for relevant switchgear voltages.

Title: Measurement of molecular weight etc. of polymers etc. using light scatter method - whereby sample is passed to photometer via micro-capillary so that there is delay between the arrival of large and small molecules at detector
Inventor: EIKEREN GEB TILLMANN
IPC: G01N15/02
Filed: 1992-11-17
Abstract: In a new procedure using light scattering tests to determine the mean molecular weight, the second virial coefficient and the radius of inertia of polymers and poly-electrolytes, and the particle size of lattices, a sample of the material being tested is passed to the light-scatter photometer via a micro-capillary in such a way that there is a delay between the arrival at the detector of small molecules and large molecules. In this way by measuring a single solution a series of concentrations can be recorded free from the disturbances which would be caused by the presence of accompanying small molecules. The sample used has a volume of about 20 microlitres. The bore of the capillary is between 0.025 ad 0.25 mm and its length is between 0.5 and 100 m. USE/ADVANTAGE - In determining the properties of large molecules in solution. The molecular weight is derived by measuring the light scatter at various solution concentration and extrapolating to a theoretical zero concentration solution. Samples of small volume are used and the concentration of the molecule in the sample is determined during the measurement. Special measures for the preparation of suitable samples are not required.

The program controller is activated if the detected position is less than the reference value.  The clamp position of the holder during each changing process is specially detected and stored as the reference for the ejection position. USE/ADVANTAGE - Abnormal positions and states of an inserted or replaced tool are reliably detected and correct and timely control measures taken before tool changer damage occurs.
