A grouting system is described for use in anchoring a reinforcing member such as a rock bolt in a hole, by the reaction of the mixed components of a primarily inorganic grouting composition so as to form a hardened grout around the reinforcing member. The reactive components include, as a first component, a particulate inorganic cement mixed with a liquid which is non-reactive therewith to form a ...

An apparatus for data storage and data retrieval comprises a system bus (14), a bus controller (20), a memory means (16), an operating system (22), a central processing unit (CPU) (12) and an input/output means (I/O) (18), the system bus (14) being arranged to provide electrical communication between the components of the apparatus subject to the bus controller (20) and the operating system (22). ...

A method of and device for attaching a web of material rolling off to a processing machine to the beginning of a fresh web that is wound on a reel. To provide a method that will inexpensively and rapidly ensure a reliable attachment between the two webs, the first web is separated upstream of a stored section with the processing machine turned off and the separated section at least partly reserved...

The transmission is made up of a symmetrical lower body (101) intended to carry with it a tool, and of an upper box (100) containing front (1) and side (3) shafts intended to be connected to a power take-off. It is possible to swivel this upper box by 180 DEG symmetrically relative to the lower box (101) in order to adapt the transmission to various uses.

The anti-cancer compound 1,1-cyclobutanedicarboxylatediammineplatinum(II) is rendered more water-soluble by formation of its inclusion compound with alpha -cyclodextrin.

A semiconductor material comprises amorphous Si containing F (a- Si : F) together with a band gap modifying material (e.g. Ge or Sn). The inclusion of F in the material permits the incorporation of the band gap modifier without degradation of other properties due to creation of dangling bonds. H may also be incorporated in the material. The material may be doped and may be used in Schottky, MIS, P...

There is disclosed new and improved photovoltaic devices which provide increased short circuit currents and efficiencies over that previously obtainable from prior devices. The disclosed devices include incident radiation directing means for directing at least a portion of the incident light through the active region or regions thereof at angles sufficient to substantially confine the directed rad...

Diluting dosage device, in which there is a dilution-liquid cylinder (20), a sample cylinder (30), a press knob (2), and a blocking valve (21). When the knob is depressed, the blocking valve is closed and the pistons (16 and 15) in the cylinders move rearwards, whereat dilution liquid flows into the dilution-liquid duct (2), and a certain quantity of sample into the sample duct (23). When the pres...

The first of the two jaw parts (2) is fixed in the body (1), whilst the second (4) is movably located to permit the required movements to be made. This movable jaw is driven by a rotating component, e.g. a shaft, chuck etc. via transmission components (10,14) fitted on the body (1).

The invention is a procedure for determining residual voltages in cross sections through a solid body.The procedure of this invention is unique in that at least two pairs of deformation sensors (3, 4) are attached to the surface of a solid body (1) and a straight groove (2) is recessed between the sensor pairs. The sensors (3, 4) in each pair are positioned on different sides of the groove (2) so ...

The cutter guide component (13,15) has surfaces which locate against the object to be cut. The guide component is L-shaped when cardboard cartons are used so that it can locate against the cover and one side. - Connected to an edge of the guide surfaces is a blade (20) retained by a mechanism which ensures that the blade is adjustable, and that its projection relatively to the guide surface edge c...
