Title: Simple and reliable determination of curing time of polymer - by dipping needle into thermostatically controlled specimen, rotating specimen, and continuously measuring force applied to needle.
Inventor: THEOBALD REINER
IPC: G01N3/00
Filed: 1992-09-22
Abstract: In a method of determining the curing time of polymers and their mixtures a pin is dipped into the test specimen for a certain distance, the force applied to the pin is measured continuously and/or the change in that distance is measured visually. A time switch (2) serves as a mechanical drive in a container (10) and it rotates (9) about the central axis (4) at a set speed (which can be altered). The container (1) is thermostatically controlled to a constant temp.; the test specimen (7) is in a dish (3) placed concentrically on the drive (2). The door (10) of the container (1) is closed and a test pin (6) in the form of a needle is dipped through a guide (5) into the specimen (7). The drive is energised and the needle (6) moves through a certain distance. The force acting on the needle is measured continuously until it reaches a value which denotes the optimal cure time. This time is determined in a calibration. ADVANTAGE - The method is simple, reliable, cheap, and gives reproducible results.

Title: Reflective surface with pattern for advertising purposes - has cut out sections on back of surface which are fines lines or curves filled with fluorescent or phosphorus material and covered with protective coating
Inventor: SIEK NORBERT
IPC: B44F1/04
Filed: 1992-10-09
Abstract: The back of the surface has the visible pattern cut out of it and these cut out sections may be fully or partially filled with fluorescent or phosphorus material. This changes the optical characteristics of the reflective layer. Alternatively, the pattern may not be filled, so the back of the surface is just the reflective layer covered by a protective coating. The cut out sections may be fine, straight visible lines, curves and points. The reflective layer is made up of several even reflective sections put together and has a three dimensional orientation. USE/ADVANTAGE - For advertising pictures or words in mirrors, bars, restaurants etc. The pattern stays constantly visible and the environmentally dangerous products are locked within the pattern. It is possible to produce practical any picture or pattern.

Title: Applicn of hard wear-resistant layer onto a grinding roll - with pockets in the roll edge regions for retention of the material being ground.
Inventor: HABERHAUER OSWALD DIPL ING
IPC: B23K20/02
Filed: 1992-10-21
Abstract: The method for applying at least one hard wear-resistant layer onto grinding rolls (used for comminution of relatively brittle materials) uses build-up welding. A layer (3) is applied onto a shell (2) of a roll body (1). In the edge regions (4,5) the wear-resistant material is applied with the use of grid welding techniques to form patterns (7,7') with open pockets (6) for retention and compression of the material being ground. The material thus retained provides autogenous wear protection. The hard wear-resistant material in the edge regions (4,5) is applied in a regular zigzag form. Such patterns form a direct extension of the layer (single or multiple) covering most of the roll grinding surface, and they extend radially to a distance equal to the layer thickness. Alternatively, they extend into the material of the roll body (1). USE/ADVANTAGE - In mfr of grinding rolls used for comminution of minerals, ores etc. Wear-resistant layers on rolls are produced simply and reliably. Worn rolls are effectively restored to high wear resistance.
