Patent FR-2013221-A1 (FR)
Title: Glass drill for boring of holes into glass components
IPC: B28D1/04
Filed: 1969-06-06
Abstract: High-speed boring of holes into glass components or plates, partic. as used in cars and vehicles, such as screens, front/side or rear light/indicator glass lenses etc., by one or a pair of constant-speed drills of improved life span. When drilling with a pair of drills, the glass component is clamped and secured on a frame with a drill arranged on either side to affect simultaneous drilling at equal speed into component from both sides and opposite each other. Boring is terminated when drill head bits have reached at least the middle of the glass thickness. The boring speed of the bits is maintained constant by a suitable motor to advance approx. 0.14 centimeter per sec. at approx. 3450-3600 revolutions per min., of the bit, which increases the life span of this drill. In comparison to customary drill bits, operating at constant pressure but with decreasing speed when advancing into the glass, which last for approx. 46000 bore holes, this constant-speed drill enables a life of approx. 260000 bore-holes for the drill bit.

Title: Magnetically stored data shift - uses soft magnetic strips saturated parallel to preferred magnetisation axis
IPC: G11C19/08
Filed: 1975-01-06
Abstract: The data is stored as magnetic domain structures in the soft magnetic strips. Non-magnetised, dynamically stable regions are formed in the strips in anti-parallel to the surrounding magnetisation direction. To shift these unmagnetised regions, the resultant of the magnetic vector field of the position dependent magnetic field configuration must be directed in parallel to the preferred axis of magnetisation and must have a gradient, along the length of each shifted region, whose magnitude can be greater than twice the domain wall coervicity field strength. In no case must the mean value of the effective magnetic field strengths of adjacent domain-walls reach the domain extinction field strength, and within the non-magnetised region the effective field strength must always be less than the nucleus formation field strength.

Title: Appts. for treating rock surrounding a well bore - has axially floating nozzles for engaging and forming perforations of predetermined size in well casing
Inventor: TAGIROV K M
IPC: E21B43/112
Filed: 1976-04-08
Abstract: Appts. for treating rock surrounding a cased well bore includes an elongate hollow housing carrying a set of radically-oriented nozzles, each communicating with the interior of the housing to receive abrasive-laden fluid supplied to the housing. Each nozzle is slidably supported by the housing so that it is pressed into contact with the casing under the influence of the fluid and its central flow passage is enlarged adjacent its downstream end. Each nozzle also has branch passages communicating with the enlarged portion of the central passage and opening to the exterior of the nozzle. Fluid initially supplied to the nozzles escapes into the well bore via the branch passages but erodes the areas of the casing isolated by the outer ends of the nozzles to form perforations of a dia. equal to that of the enlarged portions of central passages of the nozzles. Once the perforations have been established, fluid subsequently supplied to the nozzles enters the surrounding rock to effect the desired treatment, e.g. fracturing and acidising. Appts. provides for formation of perforations of a predetermined size, which ensures that virtually the entire kinetic energy of the treatment fluid is available for forming fractures.
