Abstract: The navigable-waterway construction contains a channel (1), which is formed by a weir sill (2) and weir sides (3), and a gate (4) which can be floated into position and contains a pontoon (5) with a support and ballast cells (15). In addition, the pontoon (5) contains a hollow space (9) which, isolated from ballast cells (15) of the pontoon (5), is open on the side facing the weir sill (2) and in the top part is provided with an annular extension (11). The support contains a stay (12) which is arranged in the hollow space (9) with clearance relative to its walls and relative to the inner edges of the annular extension (11) and is provided with a stop (13) which has a larger diameter than the diameter of the annular extension (11) and is arranged above the annular extension (11). Arranged above the stop (13) of the stay (12) is a damping element (10) which interacts with the stop (13) of the stay (12) and with the pontoon (5) in the closed state of the gate (4), the bottom end of the stay (12) lying below the bottom surface of the pontoon (5) in the closed state of the gate (4).

Abstract: Carboxyl esterase is inactivated by several chemical compounds such as naproxen or diclofop. By substituting or modifying certain basic residues of the carboxyl esterase, this enzyme shows improved stability properties during application. In this way it is possible to perform stereospecific hydrolysis reactions on industrial scale even at high substrate concentrations.

Abstract: Molecules of the liquid crystal filled in the liquid crystal display panel are orientated along the rubbing directions of the upper and the lower substrates and the orientation thereof tends to be twisted in one direction. The reverse domain that the orientation is twisted in the reverse direction occurs at portions of the liquid crystal. Though the reverse domain may be prevented from occurring by rubbing the substrates stronger, it is impossible to sufficiently rub the surfaces of the respective substrates since the substrates are provided with picture element electrodes thereon so that the surfaces are uneven. The liquid crystal display panel is heated to a transformation point so as to change into an isotropic phase after filling the liquid crystal, then is cooled rapidly, whereby there can be obtained a liquid crystal display panel in which the twisted directions of the orientation of the liquid crystal molecules are uniform.

Abstract: A detachable rear-end handle part (16) of a snap-off blade knife has a recess (30) and slot (34) which engage the front end (22) of a front handle part (14) and a used blade end-portion (28) only one way round and which, by virtue of different angles of recess walls (42, 44), allow only one direction of relative bending of handle parts (14, 16) to break-off the blade end-portion (28), corresponding to the side of the single blade surface (24) formed with the break-lines (26). Hence the blade is always bent the right way.

Abstract: A system and process for sizing wood chips to provide a flow of wood chips which are acceptable for feeding to a digester of a pulping system. A flow management screen station is rovided which divides an incoming unacceptable flow (F₀) into two fractional flows (F₁, F₂), neither of which is acceptable for feeding to the digester. One of the output flows from the flow management screen is concentrated in oversized and overthick chips compared to the incoming flow. The other output flow is concentrated in undersized chips and particles compared to the incoming flow. The output flows from the flow management screen are then fed to second and third screens (16, 14) which separate "overs" and "unders" from the respective flows to provide acceptable flows to the digester.

Abstract: A deflection yoke liner for mounting deflection coils on a cathode ray tube ; the liner has at least two interconnectable sections (30) with interengaging snap fasteners (40) in the form of a tab (50) and block (80) that position and fix together the liner sections. The tab has a stop or hook (62) adjacent a distal end for clasping over the block (80). The block (80) has an inlet groove (84) for guiding the tab (50) and thereby positioning the liner sections relative to one another. One of the groove and tab tapers inwardly and the other is complementary and tapers outwardly. Preferably the tapering sections of the groove and tab engage near a point of full abutment of the liner sections, by way of tapered shoulders (64) at the proximal end of the tab (50) and a narrowing inlet (88) taper on the block (80). The liner sections (30) are positively positioned as the tab (50) is advanced in the groove (84) until the hook (62) snaps over the abutment upon bringing together the liner sections (30). The block (80) can be discrete or formed by a continuous ridge. The block (80) and the tab (50) protrude axially above a surface of the flange (22), the tab width being oriented along a flange of the respective liner section (30). This mechanism gives an accurate and quick positionning of the supporting liner parts and finds use in deflection yokes for cathode ray tubes displays.

Abstract: The invention relates to hybrid photosensors produced on two distinct substrates S1 and S2, one carrying photosensitive elements (for example photovoltaic diodes 10) and the other carrying read circuits for transforming a photosensitive current into charge packets. The read circuit includes an input diode (region 12), an injection gate (14) overhanging a channel and a storage gate (16) establishing a deep potential well in the region 18 which it overhangs. The problem of the stability of the bias of the channel potential with respect to the second substrate and with respect to the input diode is resolved in the following way: first of all the channel (22) is doped with the type opposite to the substrate; next, the injection gate is highly biased negatively (-5 to -10 volts); finally, the first substrate is biased to a positive voltage with respect to the second substrate. The channel potential then becomes insensitive to the charge variations in the gate insulation. <IMAGE>

Abstract: The bridge serves for transferring goods between a ramp (32) and a loading surface (78) of road or rail vehicles. There is fixed on the two longitudinal sides of the loading bridge (10) in the region of its overall length (b) a U-shaped aluminium-alloy or steel section (12) which is at least partially open at the bottom when the bridge (10) is laid down. The U-shaped section (12) receives a securing arm (16) which can be pivoted, in a limited manner, perpendicularly to the running surface (46) about a rotary spindle (14) mounted at one end in the section legs (66, 67), said arm (16) being provided with a plurality of freely rotatable catches (18) these, however, not being displaceable in the axial direction (A). A protruding catch tab (34) of said catches (18) which hangs freely downwards is used to prevent a slipping of the loading bridge (10) towards the support (30) lying lower down or a distortion of said bridge, in the region between the ramp (32) and the vehicle loading surface (78). Furthermore, the catches (18), which are automatically folded round in the region of the lower-lying support (30), support the securing arm (16). <IMAGE>
