Abstract: A self-activated and load-independent level regulating device for connection between two relatively movable parts includes a pump having a pump chamber and a piston. The pump chamber is connected to one of the parts and the piston, which is operable in the pump chamber, is engageable with the other of the parts such that the relative axial position of the piston in the pump chamber correspond to the relative position between the two parts. An elastically deformable spring chamber containing a hydraulic fluid is disposed between the two parts, and a supply chamber containing a hydraulic fluid supply is also disposed between the two parts. A first passageway is connected between the pump chamber and the supply chamber means, and a first control valve is disposed in the first passageway. A second passageway is connected between the pump chamber and the spring chamber, and a second control valve is disposed in the second passageway, whereby the pump is actuated upon relative movement between the two parts to effect a pumping action of pressure and suction pulses between the supply chamber and the spring chamber via the first and second passageways to thereby provide load-independent, level regulation between the two parts.

Abstract: Photographic images are recorded by picking up a group of photographic images recorded in horizontal and vertical positions in substantially equally dimensioned frames (12a) to store in a storage medium (201) video signals representative of the photographic images in the order of the group of photographic images. One of frame orientations inclusive of at least the vertical and horizontal positions of the images recorded in the respective frames (12a) is selected. Then, out of the group of images, those which are in the selected orientation are selected. For the images in the vertical position, a magnification for forming a video signal which is smaller than that for the images in the horizontal position is set up. The selected photographic image is picked up to store a video signal representative of it in a store position (206) of the storage medium (201) assigned thereto. The selection, pickup and storage are caused on all the photographic images which are in the selected frame orientation. Thereafter, the above procedure is repeated on the remaining necessary frame orientations.

Abstract: Finely divided water-insoluble solid particles free of ionic charge, of about 0.01 µm upward, for example paint pigments, are uniformly encapsulated by admixing them, in an aqueous medium, with a water-insoluble monomer polymerizable to form a water-insoluble polymer free of ionic charge, in the presence of a non-ionic surface-active stabiliser, preferably a polyethoxylated alkyl phenol (at least C 8 -alkyl and preferably at least 40-50 EO groups), and then Initiating polymerization, usually with heating, with a redox system free of anionic groups. Naturally agglomerated particulate materials are effectively dispersed in situ during polymerization, thus eliminating preliminary grinding and/ or dispersion. Normal emulsion polymerisation conditions may be used, with usual emulsion-polymerization monomers free of ionic groups. The product is a suspension of polymer-encapsulated discrete particles exhibiting remarkable stability against flocculation or settling. White paint pigments, e.g. TiO., thus encapsulated exhibit increased hiding power, and colored pigments exhibit greater brilliance and color-depth in dried paintfilms. In both cases, the film has improved abrasion-resistance, and improved stain- resistance due to reduced porosity, as compared with conventional latex paints.

Abstract: In this process, the cracked gases hydrogen and carbon monoxide obtained from a catalytic methanol cracking process and carbon dioxide are admixed to the nitrogen gas or a nitrogen/hydrogen gas mixture and the methanol is admixed to the nitrogen preheated as a carrier gas and/or carbon dioxide, hydrogen or cracked gas, the mixture is completely evaporated in a evaporator and the resulting methanol vapour/nitrogen mixture is cracked in a reactor filled with a catalyst at a process temperature of 270 - 300 DEG C to give mainly CO and H2. Before admixture, the cracked gases pass through a heat exchanger for preheating the nitrogen carrier gas and, in order to remove CO2, two heat exchangers which can be switched on and off alternately and are operated with liquid nitrogen and in which alternately carbon dioxide can be frozen out in one heat exchanger, while the other can be dried and flushed with preheated nitrogen can be incorporated in the process sequence. <IMAGE>
