Title: Sealing system for hose-shaped covers or - similar packages
Inventor: HERBERT NIEDECKER DIPL-ING
IPC: B65B51/04
Filed: 1969-03-29
Abstract: Sealing system for hose-shaped covers of similar packages. The system e.g. for sausage skins uses two sealing clamps simultaneously. Before positioning the clamps, two parallel pairs of scissor like gathering- and displacement elements close, so as to separate some of the filled-in goods. The goods are then displaced over an expanding wedge, by the elements moving in opposite directions. The wedge is moveably mounted and is driven between the elements, displacing them, by a source of power independent from the drive of the displacement elements.

Patent DE-2025948-A1 (DE)
Title: Poly ( oxybenzoyl ester) coating comps
IPC: B29C51/00
Filed: 1970-05-27
Abstract: The porosity of a film of oxybenzoyl polyesters of general formula where R1 is benzoyl, lower alkanoyl or H; R2 is H, benzyl, lower alkyl or phenyl; and p is 3 to 600; is reduced by subjecting the surface to a shearing force parallel to the surface. This force may be applied by several means, e.g. a polishing wheel, a roller or a spatula. Coating a surface with this type of polyester is best done by plasma spraying, and while adherence is good the porosity is poor and the surface is rough. This treatment provides a smooth coherent coating which has good resistance to acids and solvents.

Patent DE-2109209-A1 (DE)
Title: Producing pellets - by charged carrier beams for consumable electrode
IPC: B01J2/00
Filed: 1971-02-26
Abstract: Production of pellets for consumable electrodes, comprises melting a raw material by charged carrier beams in a vacuum or protective gas atmosphere and then solidifying each molten drop on a cooling surface. By the arrangement of the cooling surface at the shadow portion, the cooling surface becomes effective over a long usage without roughening due to electron bombardments and fusion of the melt drops. Thus the solidified pellets are easily removed from the cooling surface by vibration.

Title: Grinding disc for diamond needles - has single layer of diamond grains larger than desired radius of curvature of needle
Inventor: ALBRECHT PETER
IPC: B24D11/00
Filed: 1973-10-10
Abstract: A grinding support for polishing diamond needles or pickup devices having a sharp trailing edge, intended for use with information carriers, comprises a grinding groove having the desired cross-sectional profile of the needle and having small diamond grains embedded and party projecting from the plastics of its surface. The embedded diamond grains are in a single layer in the surface and the greatest dimensions of the majority of the grains exceeds the permissible radius of curvature at the trailing edge of the needle to be produced; this maximum dimension however does not exceed twenty times this radius. Pref., the single layer of diamond grains is pressed into the thermoplastics while it is in the plastic condition, leaving a portion of the grains projecting. The average grain size is pref. is not 0.5 mu. Pref. dimensions are: max. grain size for majority of grains is 8 mu for a radius of curvature of the trailing edge of the needle of 0.5 mu. The radius of curvature (R) of the groove of the grinding plate is 0.5-2 mu. It is found that by the use of larger grains than those hitherto conventionally employed, a sharp trailing edge can be produced on the needle ground by means of the grinding plate, without this needle edge breaking away. Considerably increased grinding speeds are possible. The grinding edge and support pref. is in the form of a PVC disc with spiral grooves.
