Abstract: In processes for reducing the dissolved inorganic and organic impurities in aqueous bases in the Bayer process for the preparation of aluminium hydroxide, additives are used which require complicated process procedures and an increased consumption of base, which causes increased production costs and does not always ensure good product quality. These disadvantages can be prevented by subjecting the contaminated base Pv to electrodialysis using at least one unit consisting of an anion- and a cation-permselective membrane with the formation of an alkali metal base component Pr which is added to the cycle base of the Bayer process and a contaminated component V which is removed from the process and discarded. <IMAGE>

Abstract: An alignment means for a light source (10) emitting invisible laser light intended, for, example, as a guide beam in a laser alignment agent. The means includes a monocular (5,6), a reflecting prism (4) for deflecting part of the emitted laser light and reflecting it to the objective (5) of the monocular, and an image converter (19) for generating a visible image of the reflected laser light. 
     The problem with a heavily deteriorated monocular image due to the image converter is avoided by the converter (19) being spaced from the optical axis (7) of the monocular and by the reflected laser light solely being taken through the image converter (19), subsequent to which the now visible laser image is superimposed on the ordinary monocular image.

Abstract: In order to eliminate as far as possible leakages caused by sealing material flowing away where sealing strings made of extruded, stretched polytetrafluoroethylene are used, such leakages occurring in particular in the case of flange seals having high screw forces and narrow sealing surfaces, the sealing string contains a particulate filler of glass material. Although this filler does not impair the special properties of sealing strings of stretched PTFE, the thickness a sealing string retains after compression is doubled. This is particularly desirable in the case of flange seals which exhibit not inconsiderable distortions. Such distortions are less likely than before to lead to the material giving way at points where there is a little distance between the sealing surfaces.

Inventor: SLOB ARIE
IPC: G11C11/407
Filed: 1989-03-30
Abstract: In dynamic memories, generally a fluctuation of 10 % of the nominal value of the supply voltage is allowed. Since when reading, the input gate is applied to the supply, this fluctuation in the supply results in 20 % of fluctuation in the charge packet formed below the input gate. In order to eliminate this fluctuation and hence to increase the permitted interference margin for other interference sources, a voltage stabilization circuit is arranged between the source zone and the input gate so that the fluctuation in the supply also occurs at the source zone, as a result of which the size of the charge packet becomes independent of the supply. For the voltage stabilization circuit, use may advantage­ously be made of a band gap reference.

Inventor: BERGEMONT ALBERT
IPC: H01L27/115
Filed: 1989-01-20
Abstract: The invention relates to erasable and electrically reprogrammable non-volatile memories (EEPROM), with floating-gate transistors. The need has been perceived to provide in series with each floating-gate transistor a selection transistor which suppresses the leakage currents from the floating-gate transistors, which leakage currents may be sizeable following an operation of erasing a memory-point owing to the positive charges which may be stored on the floating gate. However the selection transistor is bulky. The invention proposes to limit the leakage currents with one global selection transistor for a complete line rather than with one selection transistor at each memory-point. This transistor (TSL1, TSL2) connects a single source line to earth at one time (SC1, SC2), that of the transistor line selected with a view to programming. The selection transistor is in fact controlled by the same word line as the floating-gate transistors of the same line. <IMAGE>

Abstract: Unbleached paper and paperboard for use as outer packaging material is coated and printed on a printing press. The unbleached rawstock must be relatively smooth and non-­porous prior to coating and printing with a Sheffield rough­ness less than about 300 units for linerboard and less than about 330 units for folding carton material. The coating formulation preferably comprises a mixture of temperature insensitive binders and pigments having a viscosity lower than normal paper coatings, and is applied in layers of about 1.5 lbs./1000 square feet up to a total of about 5 lbs./1000 square feet. Best results are obtained when the coated sur­face is doctored with a blade or fixed roll after coating and before drying to achieve a smooth surface for printing on the same or a different press.

Abstract: For the packaging of products, which are filled into tray-like containers (2), with a soft plastics film (4), a piece of film is placed around the container (2) and the film edges are folded over at the bottom. In order that as little pressure as possible is applied to the filled products (3) and the tray-like container (2) by the film (4), the film (4) is gathered at the side. This takes place by means of gathering elements (24-27) and subsequent clamping of the lateral film edges by clamping tongs (5). This gathering of the film means that it lies around the tray-like container (2) and the products filled therein with virtually no tension. <IMAGE>
