Disclosed are novel xylanases, a process for producing the enzyme, a microorganism capable of producing the enzyme, a method for the treatment of pulp with the xylanase enzyme, and a process for producing xylose or xylooligosaccharide using the enzyme.

The connection element is known as a lyre. It is particularly, but not exclusively, applicable for use in connector housings for use in the auto industry. The connector has a central insert slit (7) which separates two arms (8). The slit (7) is formed to receive a tongue which is held by elasticity between the two arms (8). The connector element has at least one such lyre with two arms (8). Each a...

According to this invention a flexible or elastically deformable ring device 4 is constructed, which can be applied to the core A to form overturned cisterns C supporting a plate 1 supporting the base of the cistern, so that they can then be disassociated from the said cistern base C, also releasing supporting plate 1 when the base of cistern C is free from core A and is sufficiently consolidated....

Process for the inerting of sludges and solid wastes containing sulphates and heavy metals, which comprises a stage of neutralisation and a stage of anaerobic reduction of the sulphate ion. A combination of sulphate- reducing bacteria and lactobacilli, with whey as the source of carbon and nitrogen, is used.

Process for the treatment of liquid effluents containing heavy metals, based on the use of a combination comprising sulphate-reducing bacteria and lactobacilli which are capable of multiplying using whey as the sole source of carbon and nitrogen.

A description follows of a catalytic composition comprising a mixture of Y zeolite and pillared clay and a process which uses this catalytic composition for the alkylation of aromatic hydrocarbons by means of long-chain linear olefins. The aromatic alkyl compounds thus obtained are useful for the preparation of biodegradable synthetic detergents.

A device for wiring solenoid valves (11) to air-distribution subbases (10), comprises a tubular member (15) housing the electrical leads (14) provided with means (17, 18) for removably connecting at one side of subbase (10); the tubular member (15) has a longitudinal slit (21) closed by an elastically yielding seal member (24) so as to allow the electrical leads (14) to pass through the slit (21) ...

The invention is realised in the final portion of the guide of containers of circular magnetic autodistributors, apparatus used to distribute small items with T shaped cross section, such as screws. The new mechanism makes it possible to eliminate jamming caused by defective or intersecting elements in the exit segment. In the segment where the parts are placed in the final portion, there is situa...

Pack of hollow radial magnetic plates for rotary electrical machines in general, consisting of a plurality of plates, equal in dimension and each one having an external perimeter at least partly different from a concentric circle with the axis of the central hole, said plates being packed in rotated position about the axis of the pack, one relative to the next one, by an angle equal to the angle b...

A skate with in-line wheels, including a shoe that is associated with a frame supporting a plurality of aligned wheels connected to the frame by means of pivot members. A pair of brackets are rigidly coupled to respective lateral sides of the shoe and are associated with front and rear pivot members.

Innerboot for sports shoes in general, including a lower part (102), that affects the foot, and an upper part (103), that affects the tibial region. The innerboot includes, at the lateral regions that are adjacent to the malleoli, wings (110) that provide a region where the lower part and the upper part overlap and slide with respect to each other. $$

The mould for casting thin slabs with improved surface quality consists of two cooled broad-side walls and two narrow-side walls. In the region of the pouring pipe entry, the broad-side walls have a speed-out which gradually and smoothly, with maximum possible radii, merges into a rectangular mould cross section over a distance downwards equal to about 75% of the mould length. The maximum ratio of...

The invention refers to the apparatus for reinforcement of the sole portion of the foot of a knitwear product manufactured in a circular knitting machine which produces hosiery articles. The machine is provided with needle heels 2, 3 which are divided into two groups, one short and the other long. In the knitting system, there is a knotting cam 1 opposite the knotting edge 5 of all the heels 2, 3 ...

A snowboard binding with step-in function holds a boot by means of front and heel brackets. The heel bracket is preferably coupled to a driving element that moves the heel bracket in the direction toward the other bracket and simultaneously downward, namely in the direction toward the snowboard surface, during the movement from the open position to the closed position. A spring piston locks the dr...
