Abstract: The device has two parallel support plates (1,2) with electrodes (3,4) enclosing a layer of a nematic liquid crystal having a cholesteric addition'  The crystal has positive dielectric anisotropy and a natural pitch, p.  The ratio of the plate separation (d) to the pitch p, is between 0.5 and unity.  The plate surfaces provide a progressive molecular twist of the crystal molecules across the layer thickness of between (Greek character pi) and 2 pi radians.  The director assumes a tilt angle of between zero and seventy degrees of arc at one surface and between five and seventy degrees of arc at the other surface. The liquid crystal displays a small energy threshold so that a pulsotary field with energy content exceeding a given threshold switches the crystal from one to another stable state. The surface of a supporting plate is provided with an orientation layer which is inhomogeneous on a microscopic scale.

Abstract: An electrical recording device for writing printing forms for printing machines is described which essentially consists of several writing units constructed as electrodes which can be individually connected to a voltage source in accordance with an image to be transmitted. In the case of a purely electrical device, the writing units consist of a stylus (20) which can be connected to a voltage source (23) via a photoconductor (21). An optical waveguide (25), in which a magneto-optical light switching module (31), which can be driven by means of current pulses (22) is interposed is used for driving the stylus (20). In one switch position, the light switching module (31) passes a light beam from a light source (28) from one optical waveguide section (27) into a second optical waveguide section (26), by which means the light rays pass through the photoconductor (21) and render it locally electrically conductive. In this manner, a potential by means of which, in conjunction with a counter-electrode (10), an electrical field (F) influencing the printing form (11) is generated is present at the stylus (20).

Abstract: This invention relates to the production of a solid oxidised coal containing humic acids. Coal with a mean particle size of less than 3mm is slurried with water and then oxidised with oxygen or mixtures of oxygen and air at temperatures ranging from 100 to 300 DEG C, at partial oxygen pressures ranging from 0,1 to 10 MPa and reaction periods ranging from 5 to 600 minutes. In the absence of catalysts, e.g. alkaline bases, the main product of oxidation is humic acids. These humic acids are not dissolved because the pH of this slurry is in the range 4 to 9. Small amounts of fulvic acids are formed and these are soluble in the water of the slurry. The coal-derived humic acids may for example find application as soil conditioners, organic fertilisers, briquettte and pellet binders, drilling fluid dispersants and viscosity control agents, whilst the coal-derived fulvic acids may be utilised for the production of fuel extenders, plasticisers and petrochemicals.

Abstract: The invention relates to a device for stacking flat articles, such as postal items. First guide means (9), which form part of a stacker head (7) and which bound a stack of articles (2) already stacked in a stacker bed (1) in a plane of stacking (D), carry out an imposed to-and-fro pulse movement between a rest position (A) and an outermost position (C) transversely to a supply line (3) and in line and level with the stack to make stack space for a short time for an article 2.2 to be stacked, which article is entering at that moment via the supply line (3). The pulse movement can be realized by hanging the first guide means (9) on the one hand by means of a first set of parallel leaf springs (17, 18) to a frame part (19, 20, 31, 32) in such a way that they can swing, and on the other hand by coupling them to the driving end (28) of drive means (25, 26) carried on bearings in the frame part. In the rest position (A) the stack pressure exerted in the plane of stacking (D) on the first guide means (9) of the stacker head (7) will (practically) completely be exerted as a sideways pushing force on the frame part. This fact can be utilized with advantage for a very accurate stack-force measurement. For that purpose the frame part is connected, on the one hand, via a second set of parallel leaf springs (33, 34) to the fixed world (35, 36, 4) and, on the other hand, via a coupling bar (37) to a force transducer (38, 39). A very small sideways displacement of the frame part under the sideways pushing force caused by the stack pressure is registered by the force transducer (39) and converted into a signal which can be used for a change of position, if any, of a stack support (8) for regulating the stack pressure.

Abstract: A main drive shaft of a power loom reaches the rated operating rpm of the loom by the time of the first beat-up of the reed, thus avoiding start-up faults in the fabric. A flywheel mass is accelerated to a start-up rpm that is higher than the rated operating rpm before it is coupled with the main drive shaft. The start-up rpm is determined automatically and iteratively, with ever-increasing accuracy in successive starts of the loom. When the main drive shaft is coupled to the flywheel mass, the flywheel mass rpm decreases simultaneously as the main drive shaft rpm increases from standstill to the operating rpm. The actual main drive shaft rpm is measured at least at the time of the first beat-up and any deviation from the rated operating rpm is evaluated by the loom control. After each start-up, a new data set is generated based on the measured values and is used to calculate an updated or modified flywheel start-up rpm in the next start-up operation so that the main drive shaft more accurately reaches at least the rated operating rpm by the time of the first beat-up of the reed.
