Patent GB-8604391-D0 (GB)
Title: Stable nitrate/slurry explosives
IPC: C06B47/14
Filed: 1986-02-21
Abstract: Explosives that are sensitized blends of inorganic nitrate. e.g., AN, particles, such as AN or ANFO prills, and an aqueous slurry comprising a thickened aqueous solution of an inorganic oxidizing salt, preferably AN, are rendered storage-stable by keeping the slurry's water content low enough, and its viscosity high enough, that the slurry is water-retentive. Water immobilization in the slurry, a requirement for storage stability, is achieved despite the slurry's flowable consistency at the time of blending. A blend containing about 25% slurry or less, is essentially in the form of a granular mass of free-flowing, high-density, slurry-bearing prills, and the slurry is sensitizable by the prills alone. As the slurry content exceeds about 25%, the blend takes on the characteristics of a thick slurry, requiring a supplemental sensitizer in the slurry perse. Slurries containing a nitrogen-base salt of an inorganic oxidizing acid, preferably monomethylamine nitrate, are preferred because this additive affords a saturated solution with lower water content, and also can act as a sensitizer.

Title: Fluid treatment
IPC: B01F3/04
Filed: 1987-06-24
Abstract: A carbonation method and apparatus is described in which carbonation is achieved by forcing carbon dioxide in gaseous form from an atmosphere thereof downwardly into a body of water to be carbonated. This may be achieved by a vaned rotor (3) rotatable about a horizontal axis or other means. The carbon dioxide atmosphere is preferably maintained at a pressure of about 100 psig (6.8 bars). The degree of carbonation may be varied by varying the time for which the carbonation operation is carried on. A flavour concentrate supply means, containing various flavours (46,48,50), is pressurized for the supply of the concentrate utilizing what would otherwise by waste carbon dioxide gas from the carbonation chamber after completion of the carbonation operation.

Title: Video image processing
IPC: H04N5/14
Filed: 1992-12-18
Abstract: The appropriate one of a list of possible motion vectors is applied to each region of a video image. An image value for that region is determined for each of four successive fields, for each of the possible motion vectors. The values for these four fields are compared and when the values are substantially the same for a given vector it is assumed that is the vector appropriate to that region. The vectors appropriate to regions of obscured or revealed background can also be assigned by comparing inter-field differences and determining regions where the inter-field differences are high for the central pair and one outer pair and low for the other outer pair of fields. To generate regions corresponding to obscured background only information from the earlier fields is used and to generate regions corresponding to revealed background only information from the later fields are used.

IPC: F42C19/08
Filed: 2000-03-10
Abstract: A method for firing electronic detonators in an electronic detonator system, said detonators being connected to a control unit via a bus. A firing command or a test firing command is sent from the control unit to the detonators, which start countdown of a delay time stored in each detonator at a synchronising point which is delayed relative to said command. On completion of the countdown, the detonators are caused, in the case of a firing command, to detonate, and in the case of a test firing command, to give a response at the point where they should have detonated if a firing command had been involved. The delayed synchronisation allows checking and control of the detonators after said command has been received. The invention also comprises an analogous method in a system with a plurality of slave control units, to which a plurality of detonators are connected, and a main control unit, the system being controlled at the command of the main control unit.

Abstract: There is disclosed an interrupt arrangement for use in a multiprocessing system where it is desired to specifically direct interrupts from one processor to any other processor. The arrangement treats the interrupt signal as a data communication between processors. In this regard, common address space is set aside, on a system basis, for interrupt signals. A sending processor first contends for the system bus and then addresses a message to a specific target processor. The message is received at the target processor over the regular communication channel and stored in a FIFO memory. Interrupt messages filter through the memory in order of arrival and cause interrupts to occur at the target processor. The information at the output of the FIFO memory controls the processing of the interrupt.
