Abstract: The apparatus consists of a first system (40) for marking on the object a first set of surface targets (10a) and a second system (42) for marking a second set of surface targets on a heat-conducting structure located in the surrounding medium (10). An infra-red waveguide (20) has one end (22) which is placed successively in contact with each surface target and which is used to transport the infra-red radiation emitted by the surface target in contact with this end. An infra-red pyrometer (2) is fixed to the other end of the guide and is provided with a lens which focuses the infra-red radiation transported by the guide on to a pyroelectric detector (8). This detector delivers an electrical signal proportional to the number of infra-red photons emitted by the surface target in question. A circuit (14) processes the electrical signal so as to determine the temperature of each surface target with a view to establishing the thermal print (P) of the object. <IMAGE>

Abstract: HSA crystals are provided in the form of tetragonal plates having the space groups P42₁2, the crystals being grown to sizes in excess of 0.5 mm in two dimensions and a thickness of 0.1 mm. Growth of the crystals is carried out by a hanging drop method wherein a precipitant solution containing PEG and a phosphate buffer is mixed with an HSA solution, and a droplet of mixed solution is suspended over a well of precipitant solution. Crystals grow to the desired size in 3 to 7 days. Concentration or reagents, pH and other parameters are controlled within prescribed limits. The resulting crystals exhibit a size and quality such as to allow performance of x-ray diffraction studies and enable the conduct of drug binding studies as well as genetic engineering studies.

Abstract: The plastic pipe has an outer wall layer (1), an intermediate layer (2) and an inner wall layer (3). The outer wall layer (1) and inner wall layer (3) contain polypropylene or polyethylene. The intermediate layer (2) contains two phases. One phase is polyethylene and the other phase is reutilised ground polypropylene reinforced with long glass fibres. The polyethylene phase of the intermediate layer allows a bond between the intermediate layer (2) and the outer wall layer (1) and inner wall layer (3) respectively. A selection of the particular fraction of the reutilised glass-fibre reinforced polypropylene phase makes it possible to determine properties of the multilayered plastic pipe, such as its elasticity. Waste material is therefore reused and moreover also employed to determine technical properties of the multilayered plastic pipe. <IMAGE>

Abstract: The invention concerns a rail fastener on concrete ties (4) or the like including resilient tension clamps (6) of steel rods in the form of a W and angled guide plates (3) for the rail base (1a). This so-called HM rail fastener is inventively improved by a special shaping of the tension clamp and angled guide plate, to simplify the securing of the rail on the concrete ties, in that the rotation of the elastic strainers which was previously necessary in HM construction when passing from the preassembly to the assembly position is omitted. This is achieved in that the angled guide plate (3), which is provided with a rib (3a) extending longitudinally to the rail foot for abutment on the rail foot (1a), contains in this rib special recesses (3b) for the reception and retention of the free ends of the tension clamp in the preassembly position. A tension clamp (6) has outer legs (6b) which with expansion of the spacing from the inner legs (6d) against the rail foot (1a) become broader and their free ends (6a) end outside the middle portion (6e) and wherein the inner legs (6d) of the tension clamp (6) which surround the tie screw (5) are designed so that in the preassembly position they abut with their center portion (6e) the shaft (5a) of the tie screw, while the head (5b) of the tie screw (5) overlaps the inner leg (6d) in the assembly position. In a special embodiment, the tension clamp is so designed that its center portion permanently surrounds the tie screw (5), and its inner leg portions are brought together except for a small spacing.

Abstract: Process for the preparation of urea in which 
- in a reaction zone a carbamate and free ammonia containing urea synthesis solution is formed from carbon dioxide and an excess of ammonia, 
- in a stripping zone at least part of the carbamate that is present is decomposed with carbon dioxide as stripping gas, 
- the carbamate decomposition products together with part of the excess of ammonia and the stripping gas are removed from the stripping zone as gas mixture, 
- part of the gas mixture obtained is supplied to a condensation zone, in which it condenses, after which 
- the carbamate containing mixture is supplied to the reaction zone and the stripped urea synthesis solution is processed into a urea solution or solid urea. 
     The carbamate containing solution is caused by gravity to flow out of the condensation zone to the reaction zone and from the reaction zone to stripping zone, placed at the same or virtually the same height, and the heat required for the formation of urea in the reaction zone is generated through condensation of at least part of the remainder of the gas mixture discharged from the stripping zone.

Abstract: The clutch comprises a driving part 12 and a driven part 20, engageable by respective sets of teeth 24, 26. The driving part is shiftable axially to engage or disengage the clutch by introduction of fluid pressure through ports 64, 66 into a chamber 62 at opposite sides of a piston 72. The clutch is held in its engaged condition by radially-extending springs 32 which act through rollers 34 on a camming surface 50 of a hub 10 of the clutch. The rollers 34 and camming surface 50 co-operate to define detent positions corresponding to engaged and disengaged conditions of the clutch. When engaged, the fluid pressure in the chamber 62 can be relieved, so that disengagement at the limiting torque takes place when the bias of the springs 32 acting on the camming surface is overcome. An epicyclic output stage of the clutch is shown in Figure 3. This allows selective adjustment of the output phase relative to the driving part.

Abstract: Il s'agit de prolonger la durée de vie du filtre d'un récipient de stérilisation comportant une région perforée que recouvre ce filtre, la séparant ainsi de l'espace intérieur du récipient; ce filtre est agencé sur le récipient et peut se déplacer contre la force d'un ressort de telle manière qu'en déplaçant le filtre contre la force du ressort, on libère un passage d'écoulement passant de l'intérieur du récipient à travers la région perforée et le long du filtre. A cet effet, on a prévu un disque de recouvrement entre le filtre et la région perforée, qui recouvre l'ensemble du filtre et qui se déplace parallèlement au filtre. En outre, un ressort maintient séparés le filtre et le disque de recouvrement, qui, dans leur position la plus rapprochée possible, sont juxtaposés de manière étanche. On a par ailleurs prévu sur le côté inférieur du récipient un élément de couverture fixé au récipient et qui recouvre le filtre; un ressort sépare le filtre et l'élément de recouvrement, le filtre pouvant être positionné de manière étanche contre l'élément de couverture, en sens opposé à la force du ressort; enfin, des ouvertures de passage sont prévues dans l'élément de couverture, en dehors de la région d'étanchéité où le filtre est recouvert.

Abstract: Disclosed is a system for producing a full color enlarged reproduction of a color transparency or negative (3) on a photographic paper. The system makes use of a continuous tone scanner (1) having a given contrast range to produce enlarged color separation negatives of the original transparency or negative (3) on a continuous tone photographic film (5). Prior to producing these enlarged color separation negatives, the continuous tone scanner (1) is adjusted to condensate its contrast range to accommodate the photographic paper. The color separation negatives that are so obtained may be used, after development, for producing the requested full color enlarged reproduction on the photographic paper, using a three color printing system (9) to do so. The color print that is so obtained has an excellent definition and color reproduction.
