Inventor: HOEGL ALOIS DIPL ING DR
IPC: G01T1/105
Filed: 1977-10-07
Abstract: The photoluminescence is induced by gamma radiation. The device comprises a u.v light source for the glass radiation.

Title: Films prepd. from mixt. of ionomer and polyethylene - for bags and other packages with linear tear properties
Inventor: OTTEN NORMAN J
IPC: C08L23/04
Filed: 1978-04-07
Abstract: A mixt. of resins contg. 12-95% of ionomer resin and 5-88% of low-density polyethylene resin is prepd. and extruded as a film that has the property of tearing linealy in a direction parallel to the direction of extrusion. Sacks, small bags and packages made of polymer films are usually mfd. by heat-sealing opposite leaves along a common line. If they are sealed on all sides they are difficult to open by tearing. Most films tend to stretch before tearing; most don't tear along straight lines. Films formed exclusively of ionomer or low-density polyethylene cannot be torn along straight lines; those based on copolymer can. Other properties, e.g. modulus of rigidity, resistance to shock or stretching are not adversely affected. Pref. the polyethylene resin contains is not >7.5% of an ethylene-vinyl acetate copolymer; the resin mixt. is extruded by blowing in the form of a tube; the density of the polyethylene resin is 0.910-0.960. A polymer not possessing linear properties may be co-extruded with the resin mixt. to form a co-extruded film having linear-tear props. in the direction of extrusion.

Title: Meat cutter with revolving bowl - has more than three blades and hexagonal drive bush
Inventor: WEBER GUENTHER
IPC: B02C18/20
Filed: 1978-08-18
Abstract: A meat cutter in a revolving bowl with a section of a hollow toroid, cut along the equatorial plane, has >=3 pref. 6 or 8 cutter blades and in its centre a bore with drive faces, pref. of hexagonal shape. The distance across the flats is greater than that over the corresponding drive faces of the cutter shaft; the gap is taken up by a packing bush which is secured in position by distance sleeves and clamping discs. This reduces the risk of unbalance of the conventional multi-set three-blade cutters and facilitates the cutter exchange. The higher number of cuts per shaft revolution ensures a better coverage of the cross-section of the bowl.

Title: Illegal reproduction prevention for gramophone records - involves printing identification code in ink visible only in UV
Inventor: ALT GUENTER
IPC: B41F7/06
Filed: 1979-03-15
Abstract: Gramophone records are often illegally reproduced and it is difficult to prove whether records are not genuine. To assist in the detection of illegally made records it is proposed to print identification letters on the sleeve of each record. These letters are printed with an ink that is normally invisible but which fluoresces when exposed to ultraviolet light. The letters can be printed at any desired position on the sleeve by incorporating a device in the sleeve by incorporating a device in the sleeve printing machine (100). The letters are then covered with lacquer used for coating the pictures on the sleeve.

Inventor: FOCHT HARRY
IPC: G01N33/44
Filed: 1979-08-10
Abstract: The molecular crosslinking of rubber and/or plastics can be carried out during production by admixture of a crosslinking agent. Some such agents have a definite polarity which is being lost at the moment of the radicals production. During the crosslinking rate determining process the dielectric constant of the product is determined and measured prior to and after crosslinking respectively. The two values are compared and the result serves for determining the crosslinking rate. Preferably the dielectric constant is measured by determining the electric parameters in a capacitor or in a resonator chamber. The apparatus for the dielectric parameters in a capacitor or in a resonator chamber. The apparatus for the dielectric constant measuring is incorporated in the production line behind the crosslinking station. It is either provided with the empirically calibrated scale, or is connected to a recorder, or a comparator circuit.
