Title: Method of forming a diamond impregnated cutting structure
Inventor: LOCKWOOD GREGORY T
IPC: E21B10/46
Filed: 2005-10-10
Abstract: A method of forming a diamond impregnated cutting structure such as a cutter insert, involves placing uniformly coated diamond particles in a mould, cold pressing the coated particles and then heating the compacted coated particles with a matrix material to form the diamond impregnated cutting structure. The matrix material can be selected from various metal carbides and nitrides. The heating step may be at between 1500 F and 2100 F and may be a high temperature, high pressure process or an isostatic pressing. The heating step may also comprise a hot-pressing process followed by a high pressure, high temperature process. Also claimed is an insert for a drill bit characterised by a thermally stable shearing portion on a diamond impregnated body, where at least one of the structures has a thermally stable coating.

Title: Induction pre-heating apparatus and use thereof in welding
Inventor: RATHOD ARUN
IPC: B23K37/00
Filed: 2007-09-11
Abstract: An induction pre-heating apparatus for use in welding a first object to the exterior surface of a second object is described. The apparatus comprises at least one elongate electrical conductor having at least one active length with a non-circular transverse cross-section. The non-circular cross-section is typically a flattened cross-section, with a height shorter than its width. The first and second objects may typically be pipes, and the induction pre-heating apparatus may be used in a subsea, hot-tapping procedure. The apparatus may also include an EM field focussing means (typically comprised of a plurality of laminations), which serves to direct the EM field to a required area, which may be adjacent to the induction pre-heating apparatus as opposed to underneath it. Advantages include that the pre-heating can be applied directly to the weld zone, whilst preventing over-heating of other neighbouring areas.

Filed: 1975-03-12
Abstract: 1495459 Automatic control SIEMENS AG 12 March 1975 [29 March 1974] 10205/75 Heading G3N The speed of a magnetic tape is controlled by a time varying reference having a portion that is triggered by a tape start signal rizes linearly to a nominal tape speed, and a part that is triggered by a tape stop signal and falls at a greater rate. In the embodiment, tape drive motor MO is controlled according to the difference between an actual motor signal # from tachometer TA and the speed reference from device ST via potentiometer p which sets the nominal tape speed. The device ST, described with reference to Fig. 4 (not shown), is triggered by a binary start/stop signal S, to charge a capacitor at a given rate e.g. corresponding to the maximum permissible tape acceleration to give the rising speed reference, the capacitor being discharged at a faster rate by a switching transistor to provide the falling characteristic. The motor MO, and thus the tape, may be reversible. The above system minimises gaps between adjacent blocks of stored data on the tape.
