Abstract: In order to influence areawise the density of a copy (P) that is to be produced of an original (N), the copying light of a copying light source (6) is attenuated areawise by a mask (11) having different density areas. The selection of a suitable mask area is performed by analysing the locally varying density characteristic of the original (N) and by comparison with the locally varying density characteristic, filed in matrix form in the computing and evaluating unit (5), of the mask (11) in accordance with prescribable criteria. In the exposure station (2), the associated photographic copier has a mask (11) arranged on a sliding device (12). The sliding device (12) can be slid, in accordance with control signals determined and generated by comparison in the computing and control unit (5), in a plane (E), parallel to the transport plane (T) of the original (N), in the beam path (L) of a copying light source (6).

Abstract: A falling film concentrator composed of alternately stacked feedstock plates (10) and steam plates (20) for concentrating a highly heat-sensitive liquid feedstock at a high concentration ratio with heating steam without impairing its flavor and quality, in which the width of a heating flow passage (18) is gradually reduced from an inlet (12) for the feedstock toward an outlet (13) for the concentrated liquid. Thus, no scorch occurs even when the feedstock is reduced in quantity after the water contained therein has been evaporated and separated therefrom. For preventing the speed of the concentrated liquid flowing toward the outlet (13) from being increased by steam generated from the feedstock, the plate-to-plate distance between the heating flow passages (18) is gradually increased from the feedstock inlet (12) toward the concentrated liquid outlet (13).

Filed: 1992-02-13
Abstract: Devices for freezing fluids in pipelines, in order to be able to carry out repairs for example, consist essentially of a sleeve which surrounds the pipe section and through which a fluid or gaseous cooling medium flows. The gaseous cooling medium is obtained by evaporation of a low-boiling-point liquefied gas such as nitrogen. In this case, very low temperatures are used in an uncontrolled manner, which temperatures are undesirable for some pipe materials. In order to be able to carry out the freezing using a gaseous cooling medium at defined higher temperatures as well, the cooling medium in the circuit is passed through the sleeve by the connections (4, 5) for the supply and extraction of the cooling medium being connected to the pressure side (7) and suction side (10) of a fan (8). Provided in the pressure side is a device for the controllable supply of low-boiling-point liquefied gas, for example a spray nozzle (11), which is connected via a control valve (12) to a reservoir (13) for the liquefied gas. Located in the suction side is a pressure relief flap (18) for the removal of gaseous cooling medium. The inlet and outlet temperatures of the cooling medium can be detected on the sleeve by means of temperature sensors (14, 15) and are held constant at a predetermined value by means of a temperature controller (16) which influences the control valve. <IMAGE>

Abstract: The present invention provides a level detector to sense whether the level of a liquid having a nonambient temperature such as a cryogenic liquid has reached a predetermined point. A stainless steel type T thermocouple probe is provided for generating a temperature signal referrable to absolute temperature. The type T thermocouple probe is adapted to be mounted so that it submerges in the liquid when the level of the liquid has reached the predetermined point. A high thermal conductivity tube is, at one end, in good thermal contact with a thermocouple contained within distal end of the thermocouple probe and, at the other end, is exposed to ambient conditions. The high thermal conductivity tube acts to conduct heat between the ambient and the thermocouple. A thermally insulating tube encapsulates the copper tube between its ends so that heat is not dissipated along its length and the temperature signal will be a function of a sum of the nonambient temperature of the liquid and a constant divided by a convective heat transfer, which will increase in the liquid. As a result, the temperature signal will change upon submergence of the thermocouple within the liquid to indicate that the liquid has reached the point level detector.
