Abstract: PCT No. PCT/EP90/01861 Sec. 371 Date Sep. 4, 1991 Sec. 102(e) Date Sep. 4, 1991 PCT Filed Nov. 7, 1990 PCT Pub. No. WO91/07591 PCT Pub. Date May 30, 1991.The micropump comprises a silicon wafer (22), glass wafers (2, 24) and a control element (26). The wafer (22) is machined to define an inlet valve (36), a pump chamber (34) and an outlet valve (48). The inlet valve (36) comprises a membrane (40) defining an upstream compartment (38) and a downstream compartment (62), an orifice (42) and a sealing ring (46) surrounding this orifice. The orifice (42) is pierced at a location in such a way that, during the priming of the micropump, the fluid arriving in the downstream compartment reaches a specific and unique part (60) of the downstream compartment wall before reaching other parts of the wall. The fluid is then propelled along the wall on both sides of the part (60) by pushing the air away ahead of it and thus guaranteeing that no air bubble can be formed in the downstream compartment.

Abstract: In the process, a finely divided gypsum binder and fibres are mixed and the dry mixture is made up with mixing water. The made-up mixture is moulded to give a preliminary product. The preliminary product is pressed in a press to give the gypsum fibre board, which is hardened at the same time and thereafter, dried and optionally reworked. It is worked with a gypsum binder which consists of at least 60 % by weight of calcium sulphate alpha-hemihydrate and additionally up to 35 % by weight of calcium sulphate beta-hemihydrate and, optionally in the remainder, of inert constituents. 100 parts by weight of this binder mixture are mixed with at most 20 parts by weight of fibres. This mixture is made up with the mixing water until free from press water. The made-up mixture is introduced into a circumferentially closed mould and moulded in this to give the preliminary product. In the circumferentially closed mould, the preliminary product is pressed true to form so that the finished gypsum fibre board has a raw density of at least 1.5 g/cm<3>.

Abstract: A socket for an electric part has an electric part accommodating space, and a plurality of contacts arranged in parallel relation along at least two opposing sides of the space. Each contacts has a contact arm portion to be contacted with a contact of the electric part accommodated in the electric part accommodating space under pressure, and a curved spring portion for biasing the contact arm portion inwardly in order to exert a pressure contacting force to the contact arm. The socket also has a pivotable lever vertically pivotably supported along a row of the contacts, an operating portion formed on one end of the pivotable lever and adapted to operate the pivotable lever upwardly and downwardly, and an acting portion formed on the other end thereof and adapted to exert an outward force to the contact. When the pivotable lever is pivoted downwardly by the operating portion, the acting portion displaces the contact arm portion of the contact outwardly against the resiliency of the spring portion so that the contact arm portion is separated away from the contact of the electric part.

Abstract: Continuous production of sugar crystals from syrups following the process consisting of a first stage (10) where the crystallization is carried out by evaporation while supplying heat and a second stage (14) where crystallization is carried out by cooling. 
<??>In accordance with the invention, the first stage is conducted so that the cooked mass produced has a low solids content (Brix) and a low supersaturation coefficient and this cooked mass is subjected to a pressure reduction, in a tank (12), which causes the rapid evaporation of a certain volume of water and a notable increase in the supersaturation, before the second stage.

Abstract: Device intended for viewing three-dimensional television transmissions, or three-dimensional video recordings which are available in video cassette form, the objective being to compensate the flattening and apparent reduction in the size of the image through a smaller screen, or enlargement and stretching through a screen larger than the standard screen for which the programmes were made. The two views, left and right, are offset by delaying either the line synchronisation, or the video signal, by means of a delay circuit (1) and, moreover, the signal is held at its blanking level by means of a freeze circuit (2) for a period defined by a clock circuit (3). The invention can be applied to a television which may or may not be equipped to receive three-dimensional programmes, or to an accessory external to the television, connected into its antenna circuit or through its television peripheral socket. <IMAGE>

Abstract: An airspring U-bellows of elastomeric material has a high-strength support layer of two intersecting cord fabric layers. When the U-bellows is in the operating state, a rolling lobe forms which changes with the spring actions. In order to reduce the required installation space of an airspring U-bellows, an additional, rubberised fabric double layer of two intersecting cord fabric layers is arranged in the bellows wall of the U-bellows. This additional fabric double layer connects with the constrained end region which is opposite the rolling lobe (17) and extends in the direction of the longitudinal axis of the U-bellows, entirely or partly over the non-rolling region of the airspring U-bellows. The filament angle of the additional cord fabric layers is smaller than the filament angle of the high-strength support layer.
