Abstract: Procédé de traitement d'une maladie proliférative de la peau, telle que le psoriasis, chez un individu dont la peau présente des zones affectées et non affectées. Le procédé comprend les étapes suivantes: (1) application locale d'un écran solaire constituant une photoprotection pour les zones affectées et non affectées de la peau; (2) attente pendant une durée suffisante jusqu'à ce que la peau des zones affectées soit pratiquement exfoliée; (3) exposition des zones affectées et non affectées de la peau du patient à un niveau sélectionné de rayonnement optique. On sélectionne le niveau de rayonnement afin qu'il soit suffisant pour traiter les zones affectées de la peau et insuffisant pour abîmer de façon sensible les zones non affectées. Le procédé permet d'améliorer l'efficacité et la sécurité du traitement au moyen d'une photoprotection sélective des zones non affectées et peut s'utiliser en photothérapie, en photochimiothérapie ou en thérapie photodynamique.

Title: Solar Tracking System
Inventor: SHARAN ANAND MOHAN
IPC: H01L31/042
Filed: 1996-12-06
Abstract: The solar tracking system maintains a solar collector with its responsive surface normal to the sun rays.  It includes a shaft supported for rotation about an axis parallel to the north-south axis of the earth, a stepper motor for intermittent rotation of the shaft at a mean rate equal to the earth's rate of rotation.  A solar collector securing assembly is located on one side of the shaft and includes a bracket, collars securing the bracket to the shaft, a support for fixing a solar collector pivoted to the bracket about a pivotal axis transverse to the shaft to vary the inclination of the support relative to the shaft and stays between the support and the bracket  to maintain  the  support  at  an adjusted inclination.  A counter-balancing system includes an arm secured to the shaft and extending normal thereto and away from the assembly and a weight adjustably mounted on the shaft. This system counter-balances the assembly and a solar collector fixed thereto irrespective of the rotational  position  of  the  assembly  about  the  shaft  and  the inclination of the support relative to the shaft. Preferably, two solar collectors are mounted on the shaft, one being an array of solar cells feeding a battery which in turn feeds a stepper motor driving the shaft through a step down gear box. The sun shadow of a pointer normal to the solar collector panel serves to properly align the panel. Alternately, the current generated by the solar cells is measured and its maximum indicates that the solar panel is properly aligned with the sun.

Title: Device for coating a substrate surface
Inventor: WISARD ANDRE
IPC: C23C14/28
Filed: 1997-03-03
Abstract: Device containing a vacuum chamber 30 and situated therein a substrate 10 and a vaporisation crucible 22 filled with inorganic materials 24. Situated in the region of the vacuum chamber 30 is an electron beam or laser gun 26, the electron or laser beam 27 of which is directed at the crucible 22. The device is employed for coating a substrate surface 18 e.g. a plastic film with a thin coating of inorganic materials, such as e.g. silicon oxides, by vapour deposition of the inorganic materials 24.   The electron or laser beam 27 of the electron beam or laser gun 26 is directed at the surface of the inorganic materials 24 in the vaporising crucible 22. The electron or laser beam 27 forms an angle .alpha. of 10 to 80° to the surface of the inorganic materials 24. On vaporising the inorganic materials 24 an overhang 25 is formed in the inorganic materials 24 and, geometrically, there is no line of sight between the vaporising inorganic materials and the substrate surface 18.   The process performed in the device leads to substrates e.g. plastic films the surfaces of which exhibit no inhomogenieties such as sprayed material, particles or droplets of inorganic materials.

Patent CA-2205227-A1 (CA)
Title: Synthesis of bis(2,2-dinitropropyl)formal (bdnpf)
Inventor: HAMILTON R SCOTT
IPC: B01J27/02
Filed: 1995-09-08
Abstract: A nonsolvent process of synthesizing bis(2,2-dinitropropyl)formal (BDNPF) is disclosed. In the process, 2,2-dinitropropanol (DNPOH) is reacted at low temperature with a formaldehyde source in the presence of a protic acid catalyst, such as H2SO4, HC1, H3PO4, or HBr. To inhibit byproduct formation, the reaction temperature is maintained from about -30 ~C to 30 ~C. Upon completion of the reaction, the reaction solution is quenched with water and washed with an aqueous hydroxide ion solution. The hydroxide ion concentration should be sufficient to neutralize the protic acid catalyst during the quenching step and to solubilize unreacted 2,2-dinitropropanol as well as other aqueous soluble byproducts in the reaction solution. The BDNPF product is extracted with a low boiling temperature polar organic solvent, such as methyl tert-butyl ether (MTBE) or equivalent solvent. The organic solvent is evaporated to yield usable BDNPF product. The resulting yield is at least 60 % based on the starting quantity of 2,2-dinitropropanol.

Patent CA-2214963-A1 (CA)
Title: Pivoting spring-mounted axle suspension
Inventor: GELB HERBERT
IPC: B60G9/02
Filed: 1997-09-22
Abstract: An axle suspension suspends a rigid axle body from a frame of a vehicle. The suspension has a pivot bearing for pivotally supporting the axle body, a spring arrangement for resiliently coupling the axle body to the frame, a thrust arm extending in a longitudinal direction between the axle body and the frame, and a steering arm extending generally horizontally and transverse to the longitudinal axis of the vehicle. The steering arm has one end connected to the frame and a second end connected by the pivot bearing to the axle body. The axle body supports rotatable wheels. According to the present invention, the suspension includes a pivot stop between the axle body and the vehicle frame.  The pivot stop is coupled to the axle at a first joint which is spaced apart from a pivot axis of the axle, and coupled to the frame at a second joint. The line connecting the two joints extends generally parallel to the main axis of the axle body. During pivoting of the axle body about the pivot axis, and during spring deflection, in which the distance between the axle body and the vehicle chassis varies, the joints move with respect to each other. The pivot stop primarily limits the axial distance between the two joints and thereby limits the pivoting angle range of the axle body. Preferably, a line connecting the two joints extends generally horizontally and transverse to the fore-and-aft axis of the vehicle.
