Title: Thermally stable diamond abrasive compact body
Inventor: MARTELL TREVOR J
IPC: B24D3/10
Filed: 1989-08-02
Granted: 1993-12-14
Abstract: A B S T R A C T            A method of producing a thermally stable diamond compact having a metal layer bonded to a surface thereof is provided.   The thermally stable diamond compact comprises a mass of diamond particles containing diamond-to-diamond bonding and a second phase  uniformly distributed through the diamond mass.   The metal of the metallic layer is molybdenum,  tantalum,  titanium or like high melting refractory metal,  nickel  or  an alloy containing a dominant amount of any one of these metals.   The method includes the steps of:            (i)      preparing an assembly of a metallic layer, a mass of diamond particles on the metallic layer and a layer of the component or components necessary to form the  second phase on the diamond particles, this component or these components having a melting point lower than that of the metallic layer;  and (ii)     placing the assembly in a canister and subjecting the assembly to conditions of elevated temperature and pressure for a period sufficient to produce the diamond  abrasive  compact,  the  temperature  being first  raised to a level where  the  component  or components for the second phase are molten allowing their infiltration into the the diamond mass and the compact to be produced, but the metallic layer is not molten, and thereafter raising it to a level where the metallic layer bonds to the thus formed compact.

Abstract: ABSTRACT     The invention relates to a method of controlling productivi-ty disturbing microbiological deposits, e.g. slime, on paper mak-ing equipment, which method is characterized by applying to any locus or surface of said equipment a deposition-controlling amount, preferably at least about 0.1 parts per million of dilu-tion water, of a cationic polymer or a cationic surfactant or a mixture thereof.      Said application is preferably performed by spraying an aqueous solution of said polymer or surfactant directly onto the equipment to be cleaned.      The invention also relates to the improved paper prepared by such a method.

Title: Optical fibre with fluorescent additive
Inventor: AINSLIE BENJAMIN J
IPC: C03C4/00
Filed: 1993-05-28
Granted: 1995-02-07
Abstract: An optical fibre for use in fibre lasers has the lasing additive, eg Er3+, concentrated in centre of the core.  Preferably the core has an inner region which contains the additive and an outer region which is dopant free.  The concentration of the dopant reduces the pump threshold for a laser and improves the gain performance for a given pump power.  The fibre is conveniently made by MCVD.  The use of Al2O3 in the inner zone appears to reduce loss of dopant during tube collapse.

Abstract: The bidirectional transmission apparatus contains as an essential element a wire matrix utilized in a two-fold or dual manner. The wire matrix comprises two groups of column conductors, each group being provided for one of the two signal transmission directions, and one group of line conductors common to all column conductors. A control unit forms a component of a microprocessor and cyclically controls the line conductors and the column conductors are synchronously scanned and activated, whereby signal transmitters and signal receivers connected to the intersection or crossing points of the wire matrix are detected and controlled in a pulsed manner. The frequency and scanning ratio of the cyclical scanning operation are selected such that even the shortest contact periods to be expected are reliably detected and that, when opto-electronic indicator or display elements are activated, a continuous light or radiation of sufficient intensity is visually discernible. Due to the functional two-fold utilization of the line conductors as well as due to the cyclical operation a high transmission capacity is ensured even if the electronic and installational expense is highly reduced. Using, for example, an 8 by 16-wire matrix there thus can be detected and activated a maximum of sixty-four call and limit or terminal switch signals as well as sixty-four signallings which are simultaneously present at the wire matrix.

Abstract: An anti-syphoning valve (12) which is suitable especially for incorporation into sanitary fittings comprises, in a housing (1), a chamber (10) into which a water inlet conduit (9), a water outlet conduit (8) and a ventilation channel lead. A resilient closing flap (16) comprises a fastening portion (18) and a closing portion (19) connected hinge-like thereto. Normally, that is, provided there is no negative pressure in the inlet conduit, the closing portion covers the opening of the ventilation channel leading into the chamber, so that, on the one hand, no atmospheric air can enter and, on the other hand, no water can escape. If, however, a negative pressure arises in the pipe system connected to the inlet conduit, the closing portion of the closing flap pivots through a certain angle until it seals the inlet point of the conduit leading into the chamber and, on the other hand, frees the ventilation channel to the chamber. In this way, no more water can flow back into the inlet conduit and to the pipe system connected thereto; on the other hand, the water passages downstream of the chamber are ventilated. The sucking back of contaminated water into the drinking-water system which is connected to the inlet conduit is thereby reliably prevented. The anti-siphoning valve is of such small construction that it can be accommodated especially in the bottom region of known sanitary fittings.
