Generator consisting of a compression chamber c where the air is introduced via a funnel, equipped with blades, at its larger end, conveyed through the inside of the rotary shaft of the entire system, as far as the said chamber, the latter producing suction, via blades connected to the shaft, facilitating the entry and compression of the air inside it. The said compression chamber is connected to ...

A foam pattern assembly includes a parting line, and a surface which is intersected by the parting line and which includes a first surface portion and a second surface portion offset from the first surface portion at the parting line. The surface is leveled so that the first surface portion is not offset from the second surface portion.

The system is used in civil engineering, in particular inbuilding of buildings orientated in one direction of hotel type.It facilitates the heating of the walls lateral to the facade fromthe heated air from an accumulated space formed parallel to thefacade. The system includes an inclined air canal (1 ) located inthe walls lateral to the facade, and above it vertical air canals(2) are built separa...

The building shall be used in civil engineering. The heatedsurface of the system is increased by the inclined south-lookingroof ducts in the form of solar air collectors. The buildingbefore its south-looking wall (3) has an air space (1) whichhouses mobile lamellas (2). In closed position the lamellas (2) inthe air space (1) form an internal (7) and external (8) air space.The internal space (7), b...

The method and the installation shall find application for filling of tubular plates for lead storage batteries of armour-plate type. The installation ensures even density and optimum phase combustion of the active mass in the whole volume of the tubular elements. The method is implemented in a mixer (1 ) in which battery palette of specific phase composition is produced containing base lead sulph...

The invention relates to a binding element intended to retain the end of a boot. It comprises a body which carries a jaw (8). The jaw (8) is movable vertically and its movement is transmitted to the return spring of the jaw, which compensates for a rearward fall. The boot sole is pinched between a support plate (25) and the sole gripper (13) of the jaw. The support plate is mounted movably about a...

Le pneumatique comporte un renforcement de carcasse constitué entièrement à partir d'une bandelette 4 bobinée circonférentiellement avec un recouvrement entre 2 tours, de façon à assurer la continuité de la carcasse.

The serial digital data link monitor circuitry operates on a single wire multiplex connection linking intercommunicating signal processing devices. The level of transmitted and/or received data (D) is compared with predetermined reference levels (GR1-GR4) to test whether the signal lies within or outside of the signal limits for data values 0 and 1. The limit values of th signal are less than or ...

Another embodiment provides a biodegradable packaging material comprising an expanded, low density, closed cell starch product, the starch having at least 45% by w...

Process for recycling scrap elastomeric materials based on polyethylene or on copolymers of ethylene and of another olefinic monomer, which are crosslinked by silane, with a view to the manufacture of regenerated elastomeric materials, especially for sheathing electrical cables. Dicyclohexylcarbodiimide or a polydicyclohexylcarbodiimide, in a weight proportion of 0.5 % to 5 % relative to the weigh...

The invention relates to a process for manufacturing a multi-layer, preferable twin-layer composite of a polystyrene foam film and a coextruded unfoamed film, especially for further processing into labels or mouldings making use of the shrinking capacity of the films, in which a polystyrene material is extruded together with nitrogen as the blowing agent and a pore former from the nozzle (16) of a...

Разпенен поливинилхлориден (ПВХ) материал се получава, като се смесват 100 мас.ч. поливинилхлорид и0,5-5 мас.ч. натриев алкилсулфонат, след което полученият състав се формува и нагрява за разпенванепри температура от 190 до 3000С в продължение на 3до 20 минути. Формуването се осъществява под налягане от 0,5 до 400 МРа и температура от 20 до 1700С. Следва нагряване в затворено пространство до 140-1...
