Patent DE-3063178-D1 (DE)
Title: Improved method of making diamond compacts for rock drilling
Inventor: BOVENKERK HAROLD PAUL
IPC: B01J3/06
Filed: 1980-11-07
Granted: 1983-06-16
Abstract: An improvement in the manufacture of diamond compacts is disclosed in which a cylindrical mass of polycrystalline diamond is surrounded by and bonded to an outer mass of metal which provides support for the diamond. The improvement comprises the use of seed diamond to grow the polycrystalline mass under high pressure-high temperature (HP/HT) conditions from non-diamond carbon, utilizing a catalyst metal contained in the outer metal annulus. Preferably, this improved process is carried out using a cup-shaped metal mass having a stable carbide content of at least 10% and a coefficient of thermal expansion slightly higher than diamond. It is also preferred to heat the sample (the outer metal mass and the inner graphite mass) directly by passing an electric current through the outer metal mass in the HP/HT process during which the polycrystalline compact is formed.

Inventor: DIMOPOULOS KONSTANTINOS
IPC: G08C19/30
Filed: 1982-10-05
Granted: 1987-07-16
Abstract: The display, alarm and control system detects whether a member has a first of two set positions or signal states by influencing a switch and observing the changed display state of a display member. The switch and the member that adopts the first position (closed contact) are arranged so that they close a circuit from a supply conductor via a first diode, the member and via one of two further diodes. One of the two further diodes is connected to the supply conductor whilst the other diode is connected to the second supply conductor.

Abstract: Conventionally absorbent sheets for meat packaging are made of absorbent cellulose laminations 18 with a cover sheet 14 of polyethylene. The laminations are compression bonded by means of a serrated wheel which forms a series of indentations along one or more lines. When moisture is absorbed the sheet 14 tends to delaminate. To prevent this a thermo-setting material such as a wax is applied along the line of indentations. A wax rivet 24 is thus formed which provides additional mechanical bonding and prevents access of moisture to the immediate region of the compression bond 22 by reason of the absorbed wax 24A.
