Patent DE-2340276-A1 (DE)
Title: Holing concrete or brittle materials - shear stress applied to small hole within outline of large hole
IPC: B28D1/18
Filed: 1973-08-09
Abstract: Holing concrete or hard rock starts from a small hole contained within the outline of the large hole. The material is exposed in a ring region round the rim of this inner hole toward the axis of the hole to a static shear stress of such magnitude that it breaks up between the area of maximum shear stress and the small hole. This annular maximum shear stress zone should be displaced parallel to the axis of the eventual hole during holing operations. The inner or small hole should lie centrally within the outline of the eventual hole and be made by a percussive tool. The tool should consist of body and blade rim of the same outline as the tool and of the same section as the hole being drilled.

Title: Support strip for row of flash bulbs - has protective shields between bulbs to prevent two bulbs firing together
Inventor: WINKLER ALFRED
IPC: G03B15/04
Filed: 1973-11-27
Abstract: The flash bulbs are attached to a strip for a magazine feed into the flash gun. The bulbs are fired inertially with each bulb fitted with a detonator. The close stacking of the bulbs can lead to two bulbs being fired at once due to heat flashes but this may be prevented by protective strips between the bulbs on the strip. The bulbs are secured to the strip by glass nipples formed on side of each bulb and pushed into a flexible recess on the supporting blocks spaced along the band. The band can be slightly flexible and can be arranged as an endless loop over transport rollers.

Title: Filter cloth of composite weave - with double interlocking weft strands flattened at their points of intersection
Inventor: FRIEDRICHS DIETER
IPC: D03D1/00
Filed: 1975-07-16
Abstract: A woven filter cloth has warp threads of greater dia. than the weft threads. The weft threads are formed with flats at the point where they cross each other so that the distance between them is less than the space formed by the intersection of two crossed weft threads with a single (thicker) warp thread, the latter determining the fineness of filtration which can be achieved. The fibres may be metal or plastic. A controlled fineness of filtration is achievable (as measured by the 'glass bead' test) in a construction which gives freedom from cloth blockages.

Title: Horizontal cylindrical reversing frame - has radial location slot for accepting flat panel for half turn before return to conveyor
Inventor: KNOOP HANS
IPC: B65G47/24
Filed: 1975-12-20
Abstract: The cylindrical frame (2) is held in a horizontal position by two circular bearing rings (7). The frame is used to turn flat panels through 180 deg. during a production process.

Abstract: Material for electrically insulating a section of an energy transmission line, esp. for insulating an end section or connection of a paper-insulated cable, by introducing into a housing around the section, consists of (1) a dry, water immiscible, non-volatile, free flowing, organic liq. having a dielectric strength of at least 6 kV/mm at a gap of 2.5 mm a dielectric constant of less than 10, and a dissipation factor of less than 0.2, and remaining in the liquid state at 0 degrees C. and (2) at least two reactive components that are uniformly dispersed in (1), each component contg. 1-3 co-reactive gps. per molecule. Components (2) react with each other at room temp. to form a thermally stable, highly viscous thickening agent that remains uniformly dispersed in (1). Before components (2) are reacted the material has a viscosity of less than 5000cP at room temp. and after the reaction the material remains capable of flow, so that it assumes the shape of its container, and has a viscosity of at least 50,000 cP at room temp. and a viscosity charge of less than 10,000 cP over a temp. range of 25-100 degrees C. Remains stable during storage, as it is stored in two separate parts. Easily mixed and applied to cables, before reaction occurs, as a result of its low viscosity at room temp. Remains within the housing after reaction, and does not tend to leak. End sections or connections contg. the material can be handled without use of heat.
