A sticky, plastically deformable material, particularly an adhesive bead, is cut by means of a jet-like cutting medium, preferably by means of a fluid jet, particularly by means of an air jet having a diameter of approximately 0.15 mm and a pressure of between 80 to 100 bar. The method can be used in a method of automatically applying a profiled adhesive bead to the surface of a glass pane along t...

To manufacture spherical particles out of liquid phase with a narrow grain spectrum using melting temperatures of up to 1500.degree.C by generating droplets by means of vibrating nozzles, the liquid phase, the nozzle and the drop distance for the droplets are maintained at a constant temperature of 1 to 10.degree.C above the melting temperature of the liquid phase until the spherical shape of the ...

A brake actuator has a body (8) containing a pair of brake-applying members (l0, ll) which may be actuated hydraulically to separate the friction elements of a brake into engagement with a rotatable braking surface. The members (l0, ll) are interconnected by a mechanism in the form of a shaft (l2) of which respective end portions (l3, l4) are provided with reversible threaded portions of opposite ...

The invention concerns a process for producing water-insoluble water-absorbing resins, which comprises the steps of initiating polymerization of an aquaous solution containing 30 to 80 % by weight of (a) a hydrophilic vinyl monomer having a functional group and (b) a crosslinking agent by supplying the aquaous solution together with (c) a polymerization initiator to a polymerizing apparatus capabl...

Process for preparing filter dust, dredging sludge (harbour sludge) and similar waste matter for final disposal, whereby the waste matter is mixed with a cohesive matrix material, in particular clay or loam, and this mixture is treated by an addition agent which breaks down the capillarity and, by catalytic ion exchange, the hydrophilic forces of the cohesive material, the mixture produced being p...

A process for the catalytic decomposition of chlorofluoro-alkanes commonly named as "flons" into harmless substances against destructing ozone layer of the stratosphere by using the catalyst comprising iron oxide supported on active carbon at the temperature more than 300.degree.C in the presence of steam.

A machine for wrapping substantially parallelepiped box elements, typically packs of cigarettes, comprises a push rod by which each box is directed against a respective wrapper of heat-sealable material, and directed together with the wrapper into a pocket, also folders by which the wrapper is closed into a tubular sheath around the box, and a heat-seal device by which the overlapping edges of the...

A bench ramp including a plurality of mutually perpendicular and movable bars provided with a coupling member arresting the bars in a selected position and having two threaded bars engaging one another in a locking position and a pair of rocker members swingable about a common axis extending parallel to the threaded bars.

- Improvements to filter-holders with a dispensing spout found in machines for producing instant coffee beverages, particularly of the type for domestic use, comprising a supporting structure which basically supports a boiler, a pump connected to a water supply and to the said boiler and a filter-holder designed to hold the dose of coffee powder, to be placed in communication with the said boiler ...

The semiautomatic equipment included a pair of horizontal knives disposed mutually parallel, adjustable for height, and positioned a short distance from the edge of a stack of sheets for penetrating the depth of one ream, selected previously by hand. The knives are carried slidably by a beam suspended over the stack of sheets between the rails of a frame and are therefore capable of relative movem...

The pistons 4 of the gas compressor in question each consist of a pumping element 7 slidably housed, with its rod 7a, inside a corresponding seating 8 sealingly fixed onto a cylindrical body 1 and each provided, at the opposite end to that joined to the eccentric element 5 arranged on the outside of the said body, with a sealed inlet mouth 9 and outlet mouth 10 for allowing gas to pass through; ea...

The invention concerns a biological, ecological process for aging and decoloration of fabrics in a water bath comprising a phase of sizing in water of the fabric with amidase enzymes capable of interacting with the coating substances of the fabric fibers, followed by aging and decoloration of the fibers of the fabric only with cellulase enzymes, as well as heat treatment capable of suppressing all...

The invention relates to a capacitive filter arrangement for removing impulsive shaft voltages from a turbo-alternator, being of a type which comprises pairs of or single capacitors connected in parallel between, on the one side, the supply brushes for the excitation winding, and on the other side, a ground clamp. In the inventive arrangement, said capacitors (C1,C2,C3,C4 or C12,C34) are mounted b...

The present invention relates to an improved boiler for domestic systems, of the type which is provided with a series of flat hollow elements inside which the water to be heated flows and which are arranged next to one another so as to create interspaces inside which the combustion products flow and which at the end are collected by a hood provided with a part projecting from the volume of the boi...

The invention concerns a device for supplying a fourstroke internal combustion engine that comprises for each cylinder: - one or more synchronised sealing valves (11,12) that are open during both admission and exhaust; - a single chamber in the cylinder head communicating, via two distribution valves (16,17), either with the admission pipe or with the exhaust pipe.
