Abstract: (I) R=H, lower alkyl opt. substd. by aryl, halo, halo-aryl; or aryl opt. substd. by halo or CF3 Z=-CH=CH- or -CO-CH2- Z=-CH-CH2-, R=H, Me, Ph and p-F-C6H4 Z=-CH=CH-, R=Me, Ph and p-F-C6H4 I are antiandrogens useful in the treatment of such conditions as hyper androgenic acne. They may be formulated as capsules or pills. The dosage varies from 0.1-500 mg/kg. 3-Oxa-A-norpregnane-5beta-ol-2,20-dione (II) is heated with ethylene glycol in an acid medium to form 3-oxa-A-norpregnane-5beta-ol-2,20-dione-20-ethylene ketal (III). This, on reaction with R-NHNH2, gives I (Z=-CO-CH2). Reduction e.g. with LiAlH4, gives I (Z=-CH=CH-).

Title: Transistor operated electrolyte level indicator for battery - has electrode in one cell connected to transistor base
Inventor: MUTO EIJI
IPC: H01M50/569

Title: Automatically operated hinged roof light with frame - has wind and rain sensor for activating the closing mechanism
Inventor: ESSER KLAUS
IPC: E05F1/00
Filed: 1973-12-21
Abstract: The roof light consists of a framed, transparent or translucent shell which is hinged on a frame which in turn is held on a roof. These roof lights are opened for ventilating purposes and closed automatically. The actuating automatic system has wind and rain sensing elements which are coupled to the actuating system in order to ensure that the roof light is closed in the case of high wind or rain which may cause damage if the roof light is left open inadvertently. The pulses from the wind and rain sensor are transmitted along a conductor to a switching unit which triggers the actuating mechanism via the conductor and interrupts the connection between two conductors as long as wind and/or rain persists. This prevents opening of the roof light. The roof light is actuated pneumatically by solenoid valves. In the case of fire the roof light is automatically and independently opened by compressed carbon dioxide in a cylinder which actuates the pneumatic actuator.
