Abstract: A spreading station, in particular for spreading the top layers of particle boards, is proposed in which the material to be spread, which is conveyed from a storage bin (1), is divided up into several fractions of different particle size before being deposited onto the forming belt (7). For effective separation of even the finest particles, the material to be spread, coming from the storage bin (1), is first deposited onto an intermediate belt (6), the belt speed of which is many times greater than the belt speed of the forming belt (7), and is then thrown down onto the forming belt (7). <IMAGE>

Abstract: A self-venting rapid connection-release coupling for pressurized gas lines, and in particular compressed air lines, has a coupling socket (1) and a coupling plug (2). The coupling socket is provided with two locking devices (22, 23) for the coupling plug (2), and these devices can be released in succession by a motion, in the same direction, of a slider sleeve (30) on the coupling socket (1). Moving the slider sleeve from a start or coupled position to an intermediate position, a first locking device (22) is released, but the slider sleeve (30) is arrested by a locking element (47), and the plug is held by the second locking device (23). The lockig element (47) is controlled as a function of the gas pressure in the coupling plug (2), until the gas pressure in the coupling plug (2) and the line to the severed compressed air line has been reduced by venting through venting conduits (51, 53). Only after the pressure has been released and vented, can the slider sleeve (30 ) be moved to a position permitting release of the coupling plug (2) from the socket (1).

Abstract: In the case of the sealing insert (1), produced from elastomeric material, for the socket (10) of a ring-sealed pipe plug-in connection between a socket and a spigot end (16) of pipes, in particular consisting of mineral materials, the axially inner-lying lip of a double-lip ring (2), forming a seal on the outer casing of the spigot end due to lip spreading, a careful fixing of this double-lip ring and an improvement against internal pressure are achieved by there being formed on the axially inner-lying face of the axially inner-lying and, before the pushing in of the spigot end, radially inward-pointing second sealing lip a third bead ring (22), which engages positively in an axially inner-lying position behind a second bead ring (25), which is formed on the holding-ring section of the sealing insert and projects radially inwards from the holding-ring section, while at the same time a first bead ring, which is formed on the base region of the V-shaped double-lip ring to project radically outwards, engages in an axially outer-lying position behind the second bead ring. In this way, an as it were positive fixing of the axially inner-lying sealing lip of the double-lip ring is achieved, both against axially outwardly directed tensile action and against axially inwardly directed tensile action on the double-lip ring.

Abstract: To meter liquid pumped from a well (24) through a long tube (20), changes in the strain in a portion of the tube carrying the liquid are measured and used to determine when the liquid has reached the portion. Pumping cycles are counted to determine the amount of liquid that flows past the portion. The determination is based on an increase in the amplitude of the pulses indicating liquid is approaching the pump. Gaps in the pulses may be sensed and accounted for in the measurements.

IPC: B65B31/02

Abstract: Certain liquid to pasty products, used especially in the field of beauty care or pharmacy, are particularly easily damaged by contact with the ambient air. Consequently methods have been developed with a view to presenting them in vacuum packages. However, they are aimed more at the removal of the air which may remain in the package filled with product at the time when the said package is closed (by welding, by leaktight fitting of a dispensing valve, etc). In addition, no special precaution is taken during filling of the package which, taking place in the open air, cannot but give rise to the trapping of undesirable bubbles. 
<??>The present method makes it possible to rule out any inclusion of air in the product. To this end, the package which consists rather of a reservoir (R) of variable capacity, is filled while in its configuration of maximum capacity inside a hermetic enclosure where an air void prevails. More concretely, the enclosure is advantageously formed from a small cup (110) receiving the reservoir (R) and on which a bell element (210) is fitted in a leaktight manner. The bell element (210) is then connected to a vacuum pump system as well as to a reserve (250) of product (80). Communication takes place preferably by means of a non-return valve (220) arranged at the exit of an injector (200) while a dispensing cylinder (240) makes it possible to isolate a volume of product (80) equal to the maximum capacity of the reservoir (R) and then to expel it (drive it back) via a three-way valve (230).
