A void in a mine is backfilled by a backfill slurry comprising water, an inert filler, e.g. mine tailings, and a binder, e.g. cement, lime or slag, to which a gelling agent, e.g. sodium silicate, is added just before placement.

A composite sheet stock for microwave heating comprises a susceptor sheet (30) having a dielectric support layer (36), a heater layer (34) of microwave interactive material and a heat-conducting microwave reflecting layer (130). A receptacle with a self-supporting configuration for combined microwave baking and cooking of a food article, such as pizza, is constructed from susceptor stock and compr...

The invention relates to a process for labelling a nucleic acid in a nucleic probe comprising a nucleic-probe sequence suitable for hybridising with a nucleic-complementary target sequence, in which the labelling of the said nucleic acid is carried out by chemical bridging with a disclosing system to permit a subsequent detection of the hybrid thus formed. The disclosing system is based on the gua...

A transmission system in which a suitably modulated speech or data signal is combined with a low bit rate (100b/s) spread spectrum signal and transmitted simultaneously on the same channel with the modulated speech lying within the bandwidth of the spread spectrum signal. At a receiver the modulated speech or data signal is demodulated and the modulated speech or data signal together with the spre...

The invention is related to a system of identification of the location of a matrix-like sample tray on a plane (2) in an equipment for the treatment of the samples. The sample tray is placed in a frame having an L-shaped electrically conductive piece (8). The equipment for the treatment comprises a number, corresponding to the number of vertical lines of the tray, electrically conductive strips (9...

The invention relates to an instrument for sailing, which, when tacking with oscillated direction, indicates the appropriateness of the tack in an analogue manner, and a method of adjusting it. The instrument according to the invention comprises a member for sensing the direction 1 of the terrestrial magnetic field which controls the position of at least one indicating member 2, along the range of...

The chain part (1) is formed by a row of rotation-symmetrical pick-up bodies (5) joined to each other by connectors (4). The guide part (2) guides the chain part in both height and lateral directions since it has slide surfaces which conform to the pick-up body cross-sectional shape.

An arrangement for fixing an object to a mast consists of an elongate support 2 in the form of a suitably U-shaped beam, which has two guides 11 which each have two bent clamping members 14, 16 which are located one above the other and grip around the mast resiliently. The object, such as a Christmas star, is fastened to the upper part of the support and a cable 10 for power supply to light bulbs ...

In a process for covering an object by means of at least one flexible piece, a fluidized bed of particles (8) is covered by a flexible cloth (10), the flexible covering piece (12) is placed above said cloth, the object (13, 14) is placed above said cloth, pressure is applied to said object, deforming the flexible sheet and immersing the object in the fluidized bed until a mating imprint is formed ...
