  • Patent number: 6392739
    Abstract: The present invention relates to a system for the optimization of a copying light profile during copying of photographic originals in a photographic copier. The photographic copier comprises a light source for producing copying light, a number of light conducting means for guiding the copying light along a light path, and a local transmission modulator. An element with a known transmission profile is provided in the light path for being shone through, whereby no photographic original to be copied and of unknown transmission profile is found in the light path, and furthermore a transmission profile specific for the local transmission modulator is provided. The resulting copying light is measured broken down by area, and the profile of the copying light is measured and compared with a desired copying light profile. Based on this comparison, the transmission profile preselected for the copying process is optimized.

  • Patent number: 5739897
    Abstract: During the processing of an order in a photographic printer, a developed copy film strip can be scanned negative by negative and point-by-point in a scanning station of the printer. From the scan signals, density values for exposure time determination in three partial colors and details on the image field number of the scanned negative can be obtained, and these data are stored in a memory, coordinating the determined three partial exposure times with the corresponding image number. All negatives of the copy film strip are exposed successively on photographic paper on an enlarged scale, using the determined exposure times. In a further step, a number of successive negatives of the film strip are exposed on full-scale or reduced scale in matrix form onto a single sheet of said photographic paper.

  • Patent number: 5086213
    Abstract: The invention concerns a device for detecting variations in the physical state of the plastic material in a coupling piece used for welding pipes and incorporating a heating resistor, cavities which the softened material can enter and sensors for detecting the state of the material within the cavities. According to the invention, in order to obtain a weld of high quality, it is necessary for the distance between the bottom of the cavities and the part of the resistor nearest this bottom on the one hand, and for the linear dimension in the cross-section of these same cavities near their bottom on the other, to be less than or equal to the thickness of the material which is softened during the heating of the pieces. The invention applies to the control of the welding of sections of piping, particularly for the gas industry.

  • Patent number: 4918292
    Abstract: The invention relates to the automatic welding of plastic parts possessing a built-in winding. In order to carry out an automatic welding operation without risking damaging the parts by subjecting them to an excessive welding temperature, there are regulating means for varying the electrical energy supplied to the winding, in order, during the welding phase, to maintain the temperature of the winding between a minimum temperature, below which welding cannot be carried out, and a maximum temperature, beyond which the parts will be damaged. The invention is used particularly for the production of systems for the distribution of gas under pressure by means of plastic pipelines.

  • Patent number: 4837424
    Abstract: The invention relates to the conducting and to the monitoring, using an automatic machine, of the temperature rise of electrically heated components with which there is associated an identification chart comprising parameters which can be used for conducting and for monitoring this heating, the machine comprising apparatus for reading the chart and for initiating the determined heating program.According to the invention, the chart is divided into a number of zones into some of which are entered, in addition to the said parameters, additional data concerning some of them, the parameters and their associated data are read off using the said reading apparatus, and provision is made for at least some of these parameters to undergo conversions which are induced by some of the other associated zones as a function at least of the data which are contained therein.The invention applies particularly to the monitoring of welding together of plastic components.

  • Patent number: 4692160
    Abstract: In a part (2) comprised of a slightly elastic material, a collector structure (11) is arranged above a collecting cavity (19) provided with an outlet (7). The collector structure (11) is comprised of two side pieces (11a, 11b) in the form of zigzag-shaped prominences. The structure delimits a wet zone (22), while a moist zone (23) is delimited by the lateral regions (18a, 18b) of the border (18) together with a rear bead (17) and a front bead (15). The collector structure (11) is placed between the labia minora and labia majora of the woman, while the elements delimiting the moist zone come to lie outside the labia majora. The inventive urine collector enables incontinent women to freely move about without risk of their garments being contacted with urine.
