A kit or solution for use in extension of an oligonucleotide primer having a first single-stranded region on a template molecule having a second single-stranded region homologous to the first single-stranded region, comprising a first agent able to cause extension of the first single-stranded region of the primer on the second single-stranded region of the template in a reaction mixture, and a sec...

A novel technique for determining the existence or nonexistence of a test nucleotide on a strand of DNA is provided. The determination advantageously uses an exonucleolytic agent that is capable of retaining a labeled nucleotide in a primer if there is a match between the test nucleotide on the strand of DNA and the complementary nucleotide on the primer, but not if there is a mismatch. The presen...

The surface of an article (1) is heated (2) to a temperature above 800 DEG C and molten silicon is applied to at least part of the surface to form a coating (3) thereon. Subsequent patterning may be produced by photo etching (4) of at least part of the coating (3) and a further ceramic (5) is applied to the patterning. Alternatively, a thin transparent film (7) on at least part of the coating (3),...

Self-sealing envelopes utilising pressure-sensitive adhesives possess an adhesive layer (7) and a release layer (8) to protect the adhesive layer, the release layer being applied to a portion of the envelope itself.

PURPOSE:To obtain an automatic gain control method with less distortion of the amplitude of an input signal even with a wide dynamic range by changing a feedback coefficient based on a control signal. CONSTITUTION:An output signal X' is applied with absolute value processing by an absolute value circuit 2 and a difference with a reference signal Ref is obtained by an adder 3. The difference and th...

The invention relates to a retrofit kit for accumulating roller conveyors, the clearance between the accumulating rollers of which is greater than the supporting element (8) of a container (4) to be transported, the kit for each accumulating roller (1) to be retrofitted consisting of at least one tubular rolling element (2) surrounding the accumulating roller (1), and also comprising a transmissio...

The injection-moulded links of an endless conveyor belt (4), especially designed for moving products through a treatment unit, comprise a number of flat link portions (8) with recesses (10) defined by pulling arms (9), said link portions (8) having slits (12) and said recesses (10) being adapted to receive link portions of an adjacent link so that a pivoting pin (7) passing through the pulling arm...

Buffer storage unit for accumulating and releasing, in rows which are equidistant or have a programmed timing, products which arrive from a continuous advancement line and are arranged in non-equidistant rows, including a first conveyor belt (2) and a second conveyor belt (3) which are respectively actuated continuously and stepwise, and which have respective active portions (2a,3a) extending hori...

Metallic silver is deposited upon the surface of a nonconducting substrate using a multi-step wet deposition process. The surface is cleaned, and then activated in an aqueous solution containing stannous tin. The silver is deposited as a colloidal material from an aqueous solution of a silver-containing salt, a reduction agent that reduces the salt to form the metallic silver, and a deposition con...

A gunite mass comprises chromomagnesite, pitch coke and quartzite in the following ratio of components, in per cent by weight: pitch coke 20-25, quartzite 20-30, chromomagnesite the balance.

The present invention regards a method for determining the surface weight of a mineral wool mat (26), in which the mineral wool is transported from the spinner aggregate (13) to a collector band (64, 25) worn by a gasformed transportmedium. Some property of the gas formed medium at the time of separating same from the mineral wool shaped is measured and used for controlling the speed of the collec...

In the erection of rectangular tray-type cartons from blanks of foldable sheet material, corner tabs which are to be uppermost in the erected carton are first folded up from the plane of the blank, which is then passed through a die by a punch to form the side wall. On completion of the stroke of the punch, the pair of opposed elongate panels which carry the uppermost tabs are folded outwardly by ...
