The adhesive members (106) are dispersed along the inner surfaces of the substrates (102, 103) at a rate of 100 members/mm² or less with an average adhesion area per member of 1.25 x 10⁻³ mm² or less so as to satisfy the relationship of: 
S A /S B  = 2.5 x 10⁻² - 1.0 %, 
wherein S A  denotes the total area of adhesion given by the adhesive members (106) and S B  denotes the area of display given by the liquid crystal device. Spacer members (105) may be further disposed between the substrates (103, 102). The spacer members (105) may preferably be in the form of rods having a length in the range of 1 to 25 µm.

Abstract: Es war Aufgabe der Erfindung, ein wirtschaftliches Verfahren zur Herstellung von 1.1-Diphenylethan mit guter Geruchsqualität auf Basis des Destillationsrückstandes der Ethylbenzolproduktion zu finden. Die bisher bekannten Verfahren, z. B. Umsetzung von Styrol mit Benzol oder Umsetzung von Benzylchlorid mit Toluol oder die oxidative Kupplung zwischen Ethylbenzol, liefern nur geringe Ausbeuten und benötigen teure Einsatzstoffe. Gelöst wurde die Aufgabe dadurch, daß man den Destillationsrückstand der Ethylbenzolproduktion zunächst einer Destillation unterwirft, das Destillat dann mit Schwefelsäure behandelt, die Schwefelsäure-Phase abtrennt, die Ölphase mit Natronlauge und Wasser wäscht und die so erhaltene Ölphase einer zweiten Destillation unterwirft. Das Produkt wird auf dem Riechstoffsektor angewendet.

Abstract: A screening device, in particular for charging excavator- and wheel-loaders, has a screening trough  (2) the base (3) of which consists of at least one flexible, curvedly sagging mat (4) provided with screening openings (19), the ends of which mat (18, 18') are designed so that they can be lifted and lowered relative to one another. Arranged below this base is a conveyor belt (25) which catches and carries away the screened material. The screening trough has a pregrating (29) through which the earth is fed into the trough. One end (18) of the mats is fastened to the charging side of the trough. The other end (18') is guided via supporting rollers to a drive mechanism (14) which lifts and lowers the mats. The lifting and lowering speed and the displacement are chosen in such a way that the material to be screened is set in rolling motion. By suitable inclination of the screening device, the screening residues travel to the end of the trough and fall out there. The material which is capable of being screened falls through the mats onto the conveyor belt and is carried away. <IMAGE>

Abstract: This invention relates to balancing thrust on rotors. For example the invention relates to balancing the thrust on the rotor of a compressor. 
     A single stage compressor (10) with an overhung rotor for process gas having one end of the compressor rotor exposed to atmospheric pressure and the other rotor end exposed to suction pressure can incur an extremely large unbalanced load on the thrust area of the rotor as a result of the imposed pressure differential between atmosphere and suction pressures. At low operating speeds, such as at startup or shutdown, the imposed loading is known to exceed the load factor for which the thrust bearing was selected. For that reason, it has been necessary to improvise in order to allow low speed operation when excess thrust load is being incurred.

Abstract: A non-volatile memory comprises an array of ferroelectric capacitors (202A, 202B,.....) each connected to one row and one column select line (R₁, R₂,..., C₁, C₂,...) through a network of four diodes (D₁, D₂, D₃, D₄). The select lines are connected to a power supply (V) or ground to access one of the cells. The diodes (D₁, D₂, D₃, D₄) are configured to provide a conducting path between a power supply (V) and ground including the accessed cell while isolating all other cells from the power supply (V) and ground. Each select line (R₁, R₂,...; C₁, C₂,...) comprises two control lines (R₁₊, R₁₋,...;C₁₊, C₁₋,...) driven by a respective row or column driver circuit (12₁,...; 18₁,...) which includes two bipolar switching transistors (Q iA , Q iB ,) respectively controlling the two control lines. A read operation consists of writing logic 1 into the accessed cell to obtain an output voltage from a resistor 204 of a current sensor 22, and then writing the read-out bit back into the accessed cell if that cell stored a logic 0.

Abstract: The apparatus is composed of rollers of axis (a), (d), (e), (b) and (c) which are horizontal and parallel and are supported between two rails (20) and (21) mounted on feet and assembled by the cross-members (27), (28), (29). The grading is effected by the diverging translational motion of the conveying wire, guided by grooves, from the roller of axis (a) to the roller of axis (b). The wire is wound in two sets of turns circling alternately, one the rollers of axis (a), (d), (e), (b) and the other the latter rollers plus the roller (c). Looped over itself and held taut by the screws (54), the wire forms three layers and intersects without touching. On the rollers of axis (d) and (e), the grooves are off-centred in order to cause the wire to oscillate and to facilitate the grading, the graded product being recovered in receptacles beneath the layers. The apparatus according to the invention is intended, in particular, for the grading of table mouldings. The model described has a space requirement of 0.15 m<3>, weighs 20 kg and has a power consumption of 50 W for a capacity of 400 kg/h. <IMAGE>

Abstract: The panel, transported by the plane conveyor (A), passes under an assembly of electric sensor (B), already arranged in advance according to the working code, as required by the relevant manufacturing, which establishes the setting to work of the master injection groups (either C or D) as well as of the secondary ones (E or F or G) concerned in the above manufactur­ing. When in position, the glue is injected in quantities and at set times established by the working code. As soon as this operation is accomplished, all groups that have been working are set to zero. When a pre-stored program has been carried out on a panel, the passing of the panel under an electric sensor (3 or 4), annuls the code and prearranges the assembly of electric sensors (B) to form a new code for the subsequent panel.

Abstract: In a short-trajectory projectile, the projectile body (11) will, if possible, have the same properties within the practical attack distance as the corresponding normal projectile. To reduce the trajectory of the projectile while it is in flight, the following means can be employed:
 a) The projectile tip (13) is produced from a plastic, the surface of which varies as a result of air friction during flight to such an extent that the air resistance is increased and the trajectory reduced, above all in the subsonic range.
 b) The projectile surface is covered at least partially with a plastic layer (17). As a result of the air friction, this layer is sharply modified, with the result that the air resistance increases and the trajectory is reduced.
 c) The projectile surface is roughened or provided with grooves and is smoothed by means of a plastic layer. As a result of the air friction, this layer disappears and the original projectile surface causes a reduction of the trajectory.
