Title: Prodn. of moulded plastic pointer - by thermo-forming transparent plastic film to shape, and injecting shot of polymer, with provision for illumination if necessary
Inventor: HEINRICH KURT
IPC: B29C70/78
Filed: 1991-09-09
Abstract: Injection moulded transparent plastic pointer is produced by first thermoforming a plastic film into the shape of the exterior of the pointer and then injecting the transparent polymer into this.

Patent DE-4218638-A1 (DE)
Inventor: WEICHERT REINER PROF DR ING
IPC: G01N15/02
Filed: 1992-06-05
Abstract: In order to determine fine particle size distributions by scattered light measurement, a collection of suspended particles is exposed to coherent light, the scattered light pattern reproduced on the photosensitive multi-element detector of a recording device is converted into electric signals and the particle size distribution is calculated by a computer from the digitalized luminosity signals. In order to simplify the design of the device and to improve the precision of the calculable particle size distributions, the recording device is a video camera and the computer calculates the particle size distribution from the luminosity signals of the pixels of the video image by solving a Fredholm integral equation. The video camera is preferably a CCD camera. In order to modify the light exposure intensity, a rotating disk with grey filters that reduce the light intensity in various degrees is arranged in the path of the measurement rays, or the video camera is provided with an electronic shutter having a variable exposure time. Various particle size fractions may also be detected by modifying the angle between the angle of exposure to light and the optical observation angle.

Title: Process and appts. for continuous monitoring of fluid level - within a container such as the coolant level within a nuclear reactor
Inventor: RUNGE ERNST-GEORG DR ING
IPC: G01F23/22
Filed: 1992-09-24
Abstract: A process for monitoring the fluid level (10) within a container (1). The process uses a primary element (2) positioned at a fixed height (hm). The element (2) is heated to a maximum temperature, in a corresponding electrical quantity being measurable. The element is then allowed to cool to a certain minimum temperature. The measurable heating and cooling times are longer and shorter respectively, if the element (2) is covered with liquid and shorter and longer respectively if it is dry. A number of elements (2) or a single long element can be used if the fluid level is required to be determined at more than one level. Pref., the primary element (2) can be a thermocouple in which case the electrical quantity measured is the voltage. Alternately, a thermistor can be used and the electrical resistance measured. In order to measure a varying fluid level rather than whether the fluid is above or below a certain level one long element can be used, in which case the electrical output is proportional to the fluid height on the element. USE/ADVANTAGE - The process is intended to be used continuously in industrial processes. It is especially suited for monitoring the coolant level within a nuclear reactor. The precise control of the primary elements (2) temperature permits high measurement accuracy.
